Don’t be ripped off.

It’s no great secret that the sensors in earlier DSLRs can get awfully dirty, the resulting blobs of black on your image testifying to the need for lots of retouching. Just like in the film days when you received your precious emulsion back from the processing place only to find that they had a party during which they stomped on your images with hobnailed boots.

So those of us not blessed with the latest in sensor dust removal technologies (meaning 5D Mark I and like vintage camera users) have to subject their camera to a nervy-dervy sensor cleaning to get the muck off and obviate the retouching. In the Canon 5D the sensior is protected by a sheet of quartz crystal – both hard and dust attracting. Now you can play into the hands of those marketers selling you Genuine Sensor Cleaning Kits for hundreds of dollars and what do you get?

A fool and his money are easily parted.

Why, a brush with some mumbo jumbo about how it’s grease free and assembled by Chinese virgins, and a bottle of isopropyl alcohol. Enough for ten cleanings.

Well, let me introduce you to Dr.Pindelski’s $15 DIY Economy Sensor Cleaning Kit. Enough for 10,000 cleanings.

The Dr. Pindelski $15 Sensor Cleaning Kit. The moiré pattern on the sensor is caused by the point-and-shoot used to take this.

Start with a Pearstone brush for $10, add a bottle of 91% Isopropyl Alcohol (you want the most concentrated, to avoid water deposits) and some Q tips from the bathroom – the genuine soft ones, not the hard generics. Do not use Kodak Lens Cleaner – this is a very poorly thought out product and is guaranteed to leave water stains on your sensor and those will be clearly visible, and near impossible to retouch, in your images.

Go outside, take a snap of the sky at a small aperture (set the camera to manual focus if the shutter refuses to fire) and load your CF or SD card into Lightroom. Increase contrast to the maximum and all the dirt blobs and deposits will show up clearly. Remember that what you see at the top right of the picture indicates dust at the lower left of the sensor and so on, as the image on the sensor is flipped and reversed once it has passed through the lens.

Now moisten a Kleenex (use plain ones, not those infused with lotions) with the Isopropyl and dab a Q tip in the moist area of the tissue, so that the Q tip is just moist. Do not touch the cotton on the Q tip with your dirty, greasy fingers. Sensors don’t like grease – or maybe they love it too much. Set the camera to Sensor Cleaning, remove the lens and dab the area concerned based on the sky picture you just snapped.. Then, holding the camera upside down, sensor pointing to the floor, brush the sensor with a flicking action using the brush. Reinsert the card and lens and take another picture. Repeat until clean.

My last cleaning dictated no fewer than four passes, the sensor cover glass being simply filthy after a couple of days snapping at the beach.

How hard to press on that Q tip? Well, the cover glass on the sensor is very tough and it would take a Mack truck driver to damage it, but pressure is not the answer. Gentle application in the right area is the secret. You want to dab and flick, not scrub. What I studiously avoid is using a blower brush on the sensor. All that does is stir up any existing dust in the body cavity only to propel it at 100mph+ into your sensor. You don’t really want to do that, do you?

Now you can apply that $245 saved to that new lens you were dreaming about.

If all you do with your images from that wonderful DSLR is to place them on the web at some 640×480 pixels, well, you can dispense with sensor cleaning as the dust spots will not show. Your DSLR is just like the Ferrari of the guy who runs it to the supermarket to be seen and to get some milk. Feels nice. Waste of money. Probably can’t drive either.

Warning to Leica M8 users: Early versions of this faux pas of a camera came with an unprotected sensor, under the guise of superior image quality or some such rot. If you have one of those, enjoy paying Leica $500 for a sensor cleaning because I doubt I would try that on an unprotected sensor in a $6,000 body. Later M8s come with a protective glass (New! Improved! etc.) once the factory realized its error, so the above technique should be fine. You will have to do something because the chances of Leica coming out with a self-cleaning sensor are about as likely as a black man in the Oval Office. Hey, wait a minute ….

The first classic of the digital age

The Canon 5D was the first camera to bring semi-affordable full frame sensors to digital photographers and, I believe, will go down as one of the great classics of the early digital photography age, much as, say, medium format was defined by the Rolleiflex and 35mm film by the rangefinder Leica. The leap in image quality it offered from 35mm and the ability to regularly match medium format film for definition and detail with none of the pain of operation make it the greatest camera design of its time.

The new 5D Mark II is slated to arrive in the US around December and yet there is already a slew of lightly used 5D Mark I models for sale on the web. Maybe it’s the economy, but I would think the price will soften further once Mark II generates some serious upgrade volume.

Check the eBay and you will see that completed auctions average about $1,300 for a mint condition lightly used body.

But I want the 21+ megapixel sensor in the new 5D Mark II, I hear you say, which begs the question why?

Do you propose making prints larger than 24″ x 30″? Do you want to use the movie mode? Is cleaning the dust off the sensor a real pain? Well, if you answered Yes to these, you may need the Mark II. No one else does.

Two classics – Canon 5D and Leica M3

From the Canon 5D Mark II.

Vince LaForet’s work with the new Canon 5D Mark II at 1600 and 3200 ISO confirms that, for all practical purposes, grain is dead.

Click the picture for large JPGs at high ISO speeds from the new Canon body. In many you will see color fringing near the corners suggesting Canon has some way to go to better Leica in its optics, albeit even L lenses are mostly chump change compared to those from Germany. The fringing (correctable in post processing in Lightroom or Aperture) is especially noticeable in the snaps taken with the 45mm TS-E and the 15mm Fisheye (which I own and love). High time Canon started adding in-camera processing to fix this sort of thing. Obviously, the body ‘knows’ which lens is mounted and it’s not like Canon is ignorant of the aberration patterns in their optics. Adding a lens ‘map’ for each lens doesn’t sound like nuclear physics.

What you will not see is grain.

It would seem that the resolving power of Canon’s latest sensor significantly exceeds that of many of its lenses. I would suggest that use of any of the consumer zooms on this body is a complete waste of time – the proverbial Coke bottle lens on a Hasselblad. The cheaper non-L primes are fine (I love the fisheye, the 50/1.4 and the 85/1.8) but ‘kit’ lenses are a no-no. Garbage in, garbage out.

So, if you want grain, you are going to have to add it at the processing stage!

A real user – that I trust.

I haven written before of the exceptional commercial photography of Vince LaForet.

Click the picture to see LaForet’s first impressions of the still and movie modes of the 5D Mark II.

When a great commercial photographer extols the image quality of a camera, (“The 5D MKII camera produces the best stills in low light that I’ve ever seen – what you can see with you eye in the worst light (such as sodium-vapor street lights at 3 a.m. in Brooklyn) – this camera can capture it with ease.“) I tend to be somewhere between belief and skepticism. Is the writer conflicted? Does the manufacturer pay him with free gear or hard or soft dollars?

In LaForet’s case I trend to the belief end of the scale. He has too much great work out there to risk his reputation.

The intriguing thing about his blog entry is that he seems most enthused with the movie mode of the new camera. Who would have thought it? If he is right, then it is indeed a game changer – 1080p HD video from a DSLR! I don’t make movies (though the genre fascinates me) and don’t need the awesome low light capability, but for many these facets of the new body may put them on the upgrade path.

No more speculation.

Hop over to DPReview for all the details you could possibly want on the new Canon EOS 5D Mark II.

The new camera looks less well balanced than the old, looking top heavy to my eyes

I speculated about the features a few days ago and was dead wrong in some important ways.

• The sensor is 21 mp, similar to that in the top of the line 1Ds Mark III. Wonder how they are addressing the cannibalization of sales?
• Price. $2,700 in the US, not $3,000. This will clobber used prices for the 5D, making that a very attractive entry into full frame digital.
• Full weather sealing. Seems like they added it.

Here are some other features which add value:

• Movie mode. If you don’t like it, don’t use it. Nice to have.
• Highlight tone priority – cuts down on burned-out highlights.
• An allegedly improved LCD screen. Given how awful the one in the 5D is it’s hard not to believe Canon on this one.
• Three Custom modes, up from one. Great. Especially as that Print button is still there and still useless, though it now doubles for Live View.
• ISO 25,600 maximum, which may work well with the improved sensor. We will see. If so the expense of ultra large aperture lenses can largely be avoided, as this is three stops faster than the 3,200 on the 5D.
• Wireless file transmission using the new removable handgrip. Great for studio previews.
• The ability to fine tune the focus setting for up to 20 lenses – a great way of keeping lens cost down by forcing the user to tune the lens to the body.

And yes, Canon has still to Fix that flap!

All in all, a worthwhile update and a boon for those looking to get a 5D whose used price will likely head south of $1,500 with the glut of amateurs updating for the latest and greatest. Don’t knock them. These gear heads are your friends. If you can live without the new features (sensor dust removal is nice!) then save $1200 and get a 5D.
