Things that go ‘Click’

My favorite street snapper

As much fun as it gets.

Leica M10, 35mm f/2 Canon LTM and 75mm f/1.9 Voigtländer Ultron.

When I bought my first Leica M3 in 1971 it was about as fast a street snapper as there was. Later autofocus, anti-shake and auto exposure were added to more modern cameras by the great Japanese camera makers and the Leica went from hero to zero when it came to operational speed. Only the stealth factor remained, something I always believed was enhanced by the amateur looking silver finish. For some reason that attracts less attention than the black favored by most camera makers today.

And speaking of stealth, no-one needs the stock red ‘Leica’ dot which screams ‘Steal me now’, so here it has been replaced with a faux silver ‘screw’ – you know, the one Leica charges $1000 more for on the M10-P. ‘P’ for ‘Professional’, you understand.

Yet the M body, now in digital form and, with the M10 and M11, finally identical in size to the film bodies of old, remains a favored street snapper. With the 35mm lens, stopped down a bit, zone focusing is as close as you get to fast autofocus, the shutter is quiet and the whole package is small and unobtrusive. With the 75mm lens, when detail is sought, a more contemplative approach to focusing is called for, especially with the unforgiving nature of the sensors in the M10 and M11. In turn these sensors will ensure you will never use film again. The M10’s sensor is as noise-free at ISO 6400 as Kodak Ektar film is at ISO 100, which is 6 stops faster. As for color rendering, the magicians at Leica have seen to it that colors are rendered every bit as well as that fine Kodak film delivers, but without dust, scratches and interminable processing delays. And film is not film any more. It’s all digitally scanned. Enough with the ‘film look’, already.

For street use I set the aperture priority exposure measurement to Auto and the film speed selector likewise, limiting the slowest shutter speed to 1/4f where ‘f’ is the focal length of the lens. That pretty much ensures an absence of movement blur, even when pixel peeping. Both lenses are 6-bit coded (by me!) which ensures that the correct focal length is communicated to the body, allowing proper determination of that 1/4f factor.

You can read more about the 35mm Canon LTM here with the 75mm Ultron profiled here.

Don’t for one moment think that there is any concept of value with a modern digital Leica M. Even a beater M10 will set you back over $4,000 and only the truly insane – or insanely wealthy – spend the $3,000 and up demanded for a used current Leica lens. The ancient Canon LTM and Leica lenses I use, over 50 years old, and the modern sensor in the Leica body makes these optics sing. Simply stated, those old lenses are better than ever. And Voigtländer fills in the gaps with its modern Leica clones at 21 and 75mm.


TOBEM* lens.

Sure, you can take street snaps with any number of modern, inexpensive digital cameras for a fraction of the cost of that digital M body. So why use the modern Leica? Well, nothing feels quite so perfect in the hand or so satisfies with its fit and finish. The optical finder – which shows details outside the frame – is a sheer delight, now made even better with LED illumination of the finder frames and with a higher eye point for the eyeglass wearer (me!) than the finders found in the film bodies. Further, my history with the Leica M goes back over 50 years and its use is second nature to me. So there are elements of familiarity and nostalgia in my choice. The only thing I had to unlearn when moving from the M3 to the M10 is film winding. There is no film winding lever and, strangely, I rather miss it.

The M10 remains my favorite street snapper and while the M11’s 60mp sensor is tempting, I don’t need that sort of pixel density. Plus I would rather stay solvent. The 24mp sensor in the M10 delivers perfect, noise free prints at 13″x19″ at pretty much any ISO setting, and if you want to print larger the viewer will be forced to step back to take it all in. So if it’s perfect at 13″x19″, it’s perfect at any size you want.

Here is a handful of recent street snaps, all taken with the M10 and the 35mm f/2 Canon LTM:



Artcise NB36 ball head

A remarkable value.

When I documented Carmel’s gorgeous Christmas windows with the monster Nikon D3x body and the exceptional resolving power of the 35mm f/1.4 Sigma Art lens in 2014 I uses a Sirui ball and socket head on my ancient but sturdy Linhof tripod. On completion of that project I sold the Sirui as I do not do landscape photography and in the studio strobes permit the camera to be hand held rather than mounted on a clunky tripod.

Recently I have again developed a hankering for some more night time photography and needed a competent ball and socket head to mount on my old Bogen/Manfrotto 3016 monopod. While old it has only three sections, meaning just two levers to undo and tighten, and is made of light alloy. Even 1/15 second exposures with the monopod are sharp for the device removes any possibility of vertical motion, the bugbear of sharp images. The 3016 is readily found on eBay for $30 or so and is recommended without reservations. If the locking levers loosen with age they are easily adjusted and a monopod is a great deal easier to use than a tripod. It’s also a handy weapon when on the wrong side of the tracks ….

My tool of choice for nighttime street snaps is the Leica M10. Not a fast to use camera by modern standards, no AF or IBIS, but it’s a small package, inconspicuous and comes with fast lenses, my street favorites being Canon’s 35/2 and 50/1.4 offerings.

The Artcise NB36 ball head comes with two Arca Swiss QR plates to attach to the base of your camera(s). The female socket is 3/8″ so a small adapter is required if your tripod or monopod uses a 1/4″ size screw.

The head has no fewer than three spirit levels if that’s your thing, two in the top plate and one in the knob which fastens the QR plate. Good luck seeing these at night.

But the real appeal of the Artcise head is the price, which is under $20! It’s a remarkable value for a device which is nicely made, all operations are smooth and the weight capacity is a claimed hefty 33lbs. Not as much as the Sirui’s but hardly a limitation with modern 35mm and digital cameras. None of the three knobs can be fully unscrewed/removed/lost, a nice piece of engineering design. And at $18.70 it’s a keeper as the resale value is precisely zero.

Highly recommended, and some nighttime pictures from the Leica M10 should be available soon.



As delivered. The Arca plate has anti-slip rubber on the side which abuts the camera’s baseplate.


Attached to the M10. Because of Leica’s slavish devotion to a dated removable baseplate, the Arca Swiss style plate must be removed to swap the battery or storage card. The plate may clear the battery door on the M11 if mounted transversely – I don’t know. not having an M11 (I wish!)


Mounted on the Bogen/Manfrotto 3016 monopod.

Keks M-meter for Leica M – in use

Finally here!

For an index of all Leica-related articles click here.

I ordered the Keks meter for Leica-M the day I profiled it here on March 8. It finally arrived today from Hong Kong, 18 weeks later.

Why buy this? To my knowledge this is the first meter since the Leicameter – discontinued in its various guises decades ago – which offers coupling with the shutter speed dial of the Leica M for speedy shutter priority readings. Users of older Leica M film bodies have been waiting for this every bit as long and, as what follows discloses, I doubt they will be disappointed.

Nicely packed, the first impression of build quality is better than that of the Leicameter M/MC/MR/MR-4 from Metrawatt, meaning up to the standard of the contemporary Leica M2 or M3. The coarse and incorrect satin chrome of the various Metrawatt meters is replaced with a beautiful smooth finish in the Keks meter, done as it should be, and very close to that of the Leica M. Just a tad grainier. And the color match with the camera’s satin chrome is well nigh perfect. That’s close to as good as it gets. Well done, Keks.

Weight: The meter weighs 1.6ozs.

Charge as received: As received the state of charge was 40%, and rose to 90% just 15 minutes after plugging it in using a USB-C to USB-A cable. 90% to 100% took an additional 15 minutes. Not at all bad. (Keks claims 60 minutes for a full charge from flat). As the image below shows, the meter ships with a short USB-C to USB-C cable. I prefer to use a USB-A wall mounted power socket with a USB-A to USB-C cable, which is nice and fast, but the meter should charge nicely from a modern laptop or desktop computer equipped with USB-C, if maybe not as quickly.



Boxed.



Unboxed.



Connected to USB power. Just 20 minutes
from 40% to 90% charged. The state of charge
is displayed when the rear button is depressed.

Setting variables: A host of variables can be tailored. You can see how to do this by downloading the manual here. Here is how the meter is shipped, with parentheses showing my preferred setting:

  • Exposure compensation: 0 stops (Same)
  • Apertures: 1/3 stops* (1/2 stop)
  • ISO stops: 1/3 stops* (1 stop)
  • Display brightness: 50% (Auto)
  • Display on time: 15 seconds (Same)
  • Max aperture: f/1.0 (f/1.4 for my 50mm Canon LTM lens)
  • Min aperture: f/128 – rather silly really (f/22)

    * Using 1/3 stop settings with a film camera is confusing precision with accuracy.

    The last setting allows the user to dial in the 1, 1/2, 1/5, 1/10, 1/25 etc. steps for early Leica M3 bodies. Wonderful that the manufacturer thought of this. (Check my Comment, below, how to do this). As I said in my initial review, Keks is going to sell a lot of these meters and I see they are already on backorder at B&H.

    The claimed replaceable battery: At this time I have yet to summon up the courage to remove the baseplate to discover what sort of (purportedly replaceable) battery is used. The specifications state only that it is a 220mAh cell. Suffice it to say that the base is retained with four Allen head bolts and these fit a 1.5mm (tiny!) Allen wrench. Update: See the conclusion of this piece, below.

    Coupling with the camera’s shutter speed dial: The shutter speed coupling dial turns to ‘B’ smoothly whereupon it is lifted and turned further CCW to a stop. The meter can now be slid into the camera’s top plate mounting shoe, with the camera’s shutter speed dial first set to B. The process is identical to that with the earlier Metrawatt meters. The knurled ring on the meter is then turned CW until the pin drops into the corresponding slot on the shutter speed dial of the Leica. The meter is now coupled to the shutter speed dial and offers far superior ergonomics for shutter speed setting owing to the larger diameter of the meter’s knurled knob. The Keks meter engaged perfectly on my 1959 single-stroke Leica M3.

    Use with long shutter speeds: The Keks meter can display shutter speeds as long as 30 seconds. To access these you set the shutter to ‘B’, lift the knurled knob and keep turning counter-clockwise. Coupling is lost but the shutter speed dial is set at ‘B’ where you want it, and you can count the indicated seconds long exposure when making the exposure using a cable release. This function is identical to that in the various Leicameters.

    Acceptance angle: Using a point light source and a protractor I measured the horizontal angle of acceptance of the meter at 36 degrees (Keks claims 30 degrees), which is close to the 27 degrees (=90mm lens) claimed by Metrawatt for the Leicameter MR/MR-4, meaning that with the 90mm frame line invoked on the camera semi-spot readings of the area indicated by that frame line are possible with the Keks meter. Now I’m getting the sense that some real Leica M enthusiasts were involved in the design of this meter.

    Design errors: Five boo-boos, and none is a big deal.

    First, the meter displays Exposure Values (EVs) below the ISO setting, as shown below. Who on earth uses these with a Leica M, which is not equipped to display them?

    Second, why show EVs (to two decimal places!) when no decimal places are used in practice with EV equipped cameras like certain Rolleis, Retinas and Hasselblads? It would be nice if the EV display could simply be hidden as it adds useless clutter. Perhaps a piece of black insulating tape is called for?

    Third, it would be nice if the aperture was indicated as f/4 etc. not 4.0F.

    Fourth, the display sometimes indicates 1/50th (the flash setting) when it should display 1/60th, especially when moving from a slower to a faster shutter speed. This error is accounted for by sample-to-sample variations in the Leica shutter speed dial’s detents and is not Keks’s fault. Keks is to be applauded on delivering a fix – see “Shutter speed calibration”, below.

    Fifth, on one or two occasions I got wildly inaccurate readings on a first press of the rear button (the readings come on instantaneously), cured by a second button press. The errors are so egregious that you are not about to be fooled. Just press the button again.



    The EV display is below the ISO. ISOs can be changed with the two top plate buttons.

    Continuous exposure readings: A double press of the rear button is required to enable continuous readings – a ‘C’ will appear on the display to the right of the battery charge indicator. A single press will lock the reading, exiting continuous reading mode. Beautifully implemented.

    Shutter speed calibration: The shutter speed dial click stops are equally spaced on the Leica except for those between 1/30th and 1/50th and between 1/50th and 1/60th. 1/50th is the electronic flash synchronization setting and the click stops between the adjacent speeds of 1/30th and 1/60th are half the spacing of all the others. As shipped my Keks meter could not distinguish between shutter speed dial settings of 1/50th and 1/60th, showing 1/50th for both settings as the shutter speed dial was rotated toward shorter shutter speeds. So a speed of 1/60th was incorrectly shown as 1/50th. Keks includes a useful calibration function to address the issue of the set speed and the indicated speed differing, as here.

    With the shutter set at 1/60th but the meter indicating 1/50th press the power (rear) button and the ISO ‘-‘ button to enter Settings. Then use the ISO ‘+’ button to cycle to ‘Reset’. Press the power button then press the ISO ‘+’ button until you see ‘Calibrate SS’. Press the power button. The display will read ‘Shutter: B-2’. Using the ISO ‘+’ button keep pressing the button until you see ‘1/60’, then press the power button once more. What was formerly displayed erroneously as 1/50th second is now correctly displayed as 1/60th second. This calibration function works for all shutter speeds, though in my case only one shutter speed was being displayed incorrectly. Given that there will be sample-to-sample variations in Leica M bodies Keks can only be applauded for adding this function. Clearly the designers are avid Leica M film camera users. Ingenious.

    Tech specs for the sensor:. Keks uses the Vishay VML7700 sensor and you can see the full technical specifications by clicking here.

    Setting shutter speeds with the meter off: You cannot set shutter speeds on the camera when the meter is off. It must be on for these to be visible. But it’s just a quick press of the rear button to illuminate the display so, again, not a big deal.

    Battery level: This is disclosed as shown at the lower left in the image above. 4 bars = 100%. The Leicameter MR/MR-4 uses a front panel battery level check, notorious for mechanical failure. The Keks approach is better, acting as a continuous reminder in use, with no buttons to press.

    Clearance for a rewind crank: Unless your camera is one of the M4 variants with the angled rewind crank, you may prefer to fit your earlier Leica M with a rapid rewind crank, as I do. In this case clearance with the side of the meter’s case is important as you really do not want to have to remove the meter to rewind the film. As the image below shows, clearance is more than adequate:



    Clearance with the rewind crank installed.

    Use in poor light:. Far superior to the older Leicameters as the Keks meter’s OLED display is internally illuminated. I just wish it was black on white rather than white on black.

    Beyond the limit? If the light is below the meter’s sensitivity range the aperture display simply changes from an f-number to three dashed lines. Fine with me.

    Sensitivity: Keks claims EV1 at the lower end, which is 1 second at f/1.4 with ISO100 film or 1/4 second at f/1.4 with ISO400 film. My tests suggest this is fairly stated. The upper limit is stated as EV20 which is jolly bright sunshine! I could get it as high as EV21 in the brightest setting.

    Accuracy: I compared readings from the Keks with those from my Leica M10 (built-in meter) and from my Gossen Luna-Pro F under a broad variety of lighting conditions. Used properly the Keks was in agreement with both.



    On my 1959 Leica M3.

    The Keks meter for Leica M is recommended without reservation, especially at the price asked.

    Battery replacement: I screwed up my courage and decided to take the top cover off to see about battery replacement.



    A 1.5mm Allen wrench is required. A German
    Stahlwille seems appropriate!



    The four screws around the periphery of the black
    plastic plate are removed. While no thread locker
    appears to be used they are a snug fit.



    The nicely machined top plate comes off
    along with three free-floating buttons –
    power, ISO up and ISO down.

    Battery location?

    The battery is not immediately visible after this first stage dismantling. I suspect it’s under the right hand assembly – last image above – but fear that dismantling that will make reassembly difficult as it houses the shutter speed dial/rotator. So I called it quits at this point. (Check the Comment by Keks, below).

    So my suggestion to Keks – their comment below suggests they read this blog – is to publish the battery replacement procedure for those mechanically adept. The economics of sending the meter in for battery replacement likely do not solve. Now, sure, that battery should last many recharge cycles and several years, but as a legacy product – and a fine one at that – it would be nice to know that the meter can be kept functional in the long term.

Leica M10 sensor cleaning

Easily done.

For an index of all Leica-related articles click here.

Fairly recent Nikon DSLRs (D700, D800) have an effective ‘sensor shaker’ which can be set to operate when the camera is powered on or off and helps remove all but the most stubborn dust particles from the sensor. This is particularly important with Nikon lenses which are poorly dust sealed – such as the the 16-35mm and 28-300mm AF-S versions which I use. These pump mighty quantities of air into the camera’s innards, along with any airborne dust, when the zoom ring is operated. It’s so bad you can feel the air rushing in if you remove the lens and zoom it close to your cheek. Quite why Nikon does not have its lens designers vent this blast of air to the outside beats me.

The Leica M10 has no sensor shaker, possibly because the compact body is already so packed with electronics and mechanical parts that there is no room for one. It’s probably the same reason that precludes installation of an IBIS system, which would be nice to have. But Leica has a clever workaround when it comes to sensor dust detection and removal. Go to the last page of the Main Menu on the LCD and click on ‘Sensor Cleaning->Dust Detection’. You will be directed to mount a lens stopped down to f/16 or f/22, defocused and pointed at a plain evenly lit surface. I used the 21mm Color-Skopar at f/22, focused on infinity, with my test wall just inches from the camera. Take a picture and you get this on the LCD screen:



Sensor dust disclosed. Click the image for a (yecch!) larger one.

Quite a bit of dust, something which can become visible in large plain areas in images, like expanses of sky. The picture on the LCD screen is rendered in the same orientation as the camera, as the red lens mounting index at left indicates.

Now go to Main Menu->Sensor-Cleaning->Open Shutter, first making sure your battery is fully charged. You do not want the shutter to close for lack of power when you are poking around in there. If the battery charge is below 40% a warning message requesting the battery be recharged will appear. Holding the camera upside down, LCD to the ceiling, blow in some air using a rubber blower bulb, directed at the sensor, being sure not to touch the surface protective glass, and redo the sensor dust image. Do not use compressed gas of any sort. The goal is to loosen dust particles so they can drop off, not blast them further into the innards of the camera. I got this:



Sensor dust gone.

Nice implementation by Leica and very easy to work with. The sensor is now clean as a whistle. If things had not improved I would have cleaned the sensor with an antistatic brush. Had that failed I would have resorted to a wet cleaning solution. I have used this product with success, and it leaves no residue, but despite the listing it does not come with a microfiber cloth, so make sure you have one. I cut a business card in half lengthwise and wrap the cloth around it. This makes for a flexible ‘wand’ and I spritz the tip of the cloth a couple of times, no more – you want moist not wet – with the solution and gently swipe the sensor’s cover glass this way and that. (I avoid Q-tips, finding them far too inflexible, meaning they risk damage to the protective glass on the sensor). Then a couple of puffs of air from the rubber bulb and you are done. This works for any digital sensor, not just the one in Leicas!

Because Leica M mount lenses do not have a zoom feature (the relatively benign variable focal length feature of the two Tri-Elmar lenses notwithstanding) the need for such sensor cleaning should be fairly rare. Further, when the lens is removed for changing, the sensor is protected by the shutter blades. So it’s not that easy for dust to get in there.

I had not checked for sensor dust since buying the camera second-hand 3 weeks ago, so only just got around to this, after noticing an out of focus blob or two in large smooth tone areas in LRc in this image, where the small aperture and short focal length of the lens emphasized dirt on the sensor.

If the surface you use to take the dust image is not evenly lit you will get a message ‘inhomogeneous (sic) image’. I got this more times than seemed right, despite using a flat, evenly lit, wall. Removing and reinserting the battery cured the issue.

A Leica M shoulder bag

Small, unobtrusive, cheap.

For an index of all Leica-related articles click here.

After the camera’s shoulder strap – and most vary from useless to down right dangerous – few accessories are more important than a carrying bag, if you propose taking more than just the camera and one lens on a photo outing. You can easily spend hundreds of dollars on a camera bag and it will almost certainly come with an aura (and labels) proclaiming ‘steal me now’.

Well, there is one born every minute.

Now that my small Leica M10 outfit is complete, meaning 21, 35, 50 and 90mm lenses, it was time to find a suitable shoulder bag to carry this hardware around. A little research discloses that the perfect Leica M outfit camera bag can be had for pennies. The dictates for the ideal shoulder bag are that it should hold a Leica M with, say, three or more lenses, one of those on the body. It should therefore have two dividers, be some 8″ long, 6″ tall to accommodate the M vertically and 4″ across for a like reason. Closure should be with a velcro flap like the one on the Thinktank.

Amazon lists over 30,000 bags (!) and the closest I could come to the specifications above is the oddly named Besnfoto. It has only one velcro divider but I have a bunch of these – so many years, so many bags – and unfortunately it does have a zippered cover underneath the outside velcro flap, but that can be left unzipped in use. Not a big issue. For the paranoid there’s a Velcro ‘anti-theft’ belt latch, illustrated below.

And did I mention anonymity? The color must be drab grey or green and the Besnfoto comes in either. Forget fancy leather and forget anything which says ‘Billingham’. Come to think of it, any label on the outside is just a bad idea. Quite the dumbest camera bag I have ever seen came from the Red Dot company. Notice anything? These were bought by the same people who like to park their BMWs with the car keys in the ignition and the doors unlocked in south central LA. But, you know, German cow full grain leather, grass fed, no antibiotics:



An invitation to theft.
The ‘legs’ are pure Schwabian silver.

Mind you, the Besnfoto is not much smarter in stock trim:



The loud label says ‘foto’ on it.
Yes, the ruler is a German Staedtler.

And they really do not want you removing that label as it’s both stitched and riveted. Whose idea was that? A few seconds’ work with pliers and a sharp blade and the label was gone. I can attest to the quality of the stitching:



No more advertising. I rather like the moth eaten look.

Here is the interior with one additional divider added:



Leica M with 35mm lens at left, 50 and 90mm
lenses center and right. A small front pocket
allows storage of spare batteries and a charger.

I do not keep any front or rear lens caps on any of the lenses. The fronts are protected by UV filters and the rears are sufficiently recessed that they will not suffer abrasion damage. In this way the lenses are immediately ready for action when a swap is called for.

In use I have the nice, broad shoulder strap on the Besnfoto slung over my head and the bag hanging at my left hip bandolier style, with the camera with its Upstrap over the left shoulder an inch or two above the bag. It must not rest on the bag as that will induce slack in the camera strap prompting the camera and lens to go crashing to the ground. This approach – bag strap on the right shoulder, camera on the left – also distributes weight nicely.

The rear of the bag has a velcro strap for attachment to your belt on those occasions when the belt is actually accessible – a nice ‘anti theft’ feature’ – along with a small carrying handle. Note the broad shoulder strap:



Belt attachment.

What if you want to stash more lenses in that bag? Goodness knows, there’s lots of room given their small sizes. Well, Leica used to make a double sided ‘lens coupler’ for just this purpose, and it is abundantly available on eBay for pennies. It permits attachment of two lenses back-to-back and works for all Leica M mount lenses other than those with deeply protruding rear elements. And there’s no need to align the mounting index on the lens with the red line on the coupler. The lens will fit in any of the four positions dictated by the bayonet mount:



The Leica M lens coupler, code #14836.
A very handy storage tool for small lenses.

The rear element of the 21mm f/3.5 Color-Skopar does not protrude enough, even with the lens focused at infinity, to strike the rear element of any other lens fitted in the coupler. However, do not try this with the earlier 21mm Color-Skopar f/4 or any early Leitz ultra wide lenses like the 21mm Super Angulons (f/4 and f/3.4) or the 21mm f/2.8 Elmarit. All of those have deeply protruding rear elements and you really do not want to use them on digital Leica Ms in any case, as they perform poorly. Here it is in use:



The 21mm f/3.5 Color-Skopar and the 35mm f/2 Canon LTM
lenses fitted to the Leica M lens coupler.

Stacked and in the bag. And there’s still room for an energy bar and a bottle of water:



35mm on the camera, 21+50mm center, 90mm at right.

This bag will not provide heavy duty protection against knocks and falls. That is not its intent. Rather it is in keeping with the Leica ethos of “small camera, small lenses, easily carried”. The Besnfoto camera bag is recommended.
