Canon’s landmark full frame camera

Excuse me while I examine my Portlait setting through the Glid

Either someone at Canon has a great sense of humor or they need better English-speaking programmers

I checked out the Canon software that came with the 5D; it’s not bad but doesn’t seem to add much to my preferred working method which is to drop all the files into an iPhoto ’06 album (RAW included), preview them in iPhoto, then fix the best ones in Photoshop for saving in Extensis Portfolio 7 in PSD format – the industrial strength, bulletproof cataloging application I use.

Here’s what I saw in a couple of menus in Digital Photo Professional, a Canon application far less competent than iPhoto for quick image manipulation, and very slow in converting from RAW:

Now do these guys at Canon have a sense of humor or what?

By the way, a RAW file saves as 8.4 mB in JPG, 36.4 mB in 8-bit TIFF and a whopping 72.8 mB in 16-bit TIFF.

Digital Dust

Or I’ll be blowed!

Mooching around some of the Canon digital fora out there one recurring complaint seeems to be how much dust the EOS 5D attracts to its viewfinder.

Now while most of my pictures over the years have been snapped on rangefinder 35mm film cameras, with few dust bearing surfaces between subject and film, every SLR I have used has been plagued with the occasional speck of dust or a hair in the viewfinder. The 5D is no different. I suspect the increased use of plastics in modern cameras makes matters worse as they seem to retain static charges more, but when I did get some dust in the 5D’s viewfinder the last thing I was going to do was blow it away.

When the maid vacuums the carpet she does just that – she vacuums. She does not blow. Blowing on dust in your camera seems the exactly wrong thing to do. You are a) Hoping to dislodge it, and b) Praying it magically exits the camera rather than getting embedded or relocated elsewhere inside. Ideally what is called for is something like those suction gadgets dentists use to remove waste water from the patient’s mouth. Until something smart like that comes along – and imagine the liability issues in a country whose residents have long ago ceased taking responsibility for their actions – you can blow (!) your money on one of the Digital Camera Cleaning Kits. For your eighty dollars you get a small bottle of Miracle Solution, probably 2 cents worth of isopropyl alcohol, a 5 cent rubber tipped blower and a Digital Brush. The latter, you should understand, grows on Digital Camels only, hence it’s price.

Me? I’ll continue using the $5 anti-static film cleaning brush I have used for years when scanning film, holding the camera just so to let gravity do its thing with the dust, and I’ll continue to avoid changing lenses in the middle of the Sahara in a sandstorm. I hate to admit it but the dust in my 5D didn’t know any better and exited stage left after I gave it a gentle shove. Oh! yes, and I’ll keep the change.

Hearst’s Castle

The only good thing to come out of yellow journalism

If the state of American journalism was headed solidly downwards in the 1930s, publisher William Randolph Hearst made sure that the pace to the bottom of the cess pit was accelerated. His populist, sensationalist brand of reporting bequeathed to the modern consumer prime time television news that focuses exclusively on the latest murder/rape/divorce, or the tribulations of some famous sports figure who has taken one steroid too many. Bread and circuses.

However, you can glean more useful information from one page of any American newspaper than from one hour of the so called prime time ‘news’ on television. Unless, that is, you read the New York Times or Washington Post, whose reporting sources tend to be Hollywood stars, supremely qualified to report on geopolitics and the fiscal state of the nation.

Thank you, Mr. Hearst.

However, Hearst’s millions did leave us with one fine attraction, namely Hearst Castle on Highway One in central California, some 20 miles from my home. Taken as a whole it’s something of an abomination, the ultimate in ‘check book collecting’, but digested in smaller pieces each of the many rooms packed with antiquities is a fine thing to behold. The Castle was Hearst’s lifetime hobby, and his architect Julia Morgan was adding to it throughout his life. Hearst would buy a medieval ceiling on one of his European jaunts (he probably wanted to read the British press to see what was really going on), bring it home and tell Morgan to build a room around it. Now that’s thinking big!

Driving by the other day on the way to see the elephant seal pups a few miles north on the beach, I took a picture from Highway One with the castle rising magnificently in the distance on top of the hill some mile and a half away. I had despaired of ever getting this right on film, as the long lens required only emphasized the atmospheric haze, but as I had my 400mm Leitz Telyt with me I gave it a shot anyway. I finally get to try RAW, I thought.

So I set the EOS 5D on RAW, the film speed at ISO 400 and the f/8 setting on the lens yielded a 1/500th second shutter speed. The result, after dropping the snap into Adobe’s Photoshop CS2, which automatically opens Adobe Camera Raw (ACR), was disappointing. The haze had washed out the picture, and the Telyt lens, I know, does not lack for contrast.

However, a few tweaks of the sliders in ACR made things look better so I saved the file in PSD format and added the usual unsharp masking and a small tweak to the levels control and look what emerged:

Now I must confess that, so far, I have not found the Canon EOS 5D’s Fine JPG images lacking in any way. The quality is outstanding, large prints a breeze and whatever JPG processing the camera does appears unobtrusive. Digital artifacts are invisible. Best of all, the file size is relatively small – some 4 mB or so. By contrast the 5D’s RAW file is 14 mB and the processed PSD version balloons to a ridiculous 73 mB. Now that is large. So RAW appears to have a place for challenging subjects that need a lot of manipulation, but the extra processing time is not justified, for this user, on the average photograph. JPG Fine quality equals or exceeds anything from medium format and processing is fast and easy.

Still, it’s nice to know RAW is available in the overall tool kit. Now I want to retake this picture early in the morning with the castle rising from the mist as California’s sun gradually makes it visible.

Taking Rube Goldberg for a spin

That’s Heath Robinson to British readers

Having written about the complexities of getting my old Leitz 200mm f/4 Telyt to work on the Canon EOS 5D, I took the Rube Goldberg collection of lens, adapters and digital body combination for a spin yesterday, in that wonderful afternoon light you get right before a storm. Ergonomically the outfit handles unbelievably well and, mercifully, there is no wobble despite all those adapter rings.

I had the 5D set on ‘Av’, meaning I set the aperture (the lens is manual so you have no choice in the matter) and the camera sets the shutter speed. Anyway, at ISO 200 and f/5.6 the camera said 1/750 so I pressed the button. Here is the result:

I checked the screen preview on the 5D’s LCD and it looked two stops overexposed, so I took another at f/11. Now this did not smell right. Years with manual cameras have done a decent job of calibrating the exposure meter in my brain, and f/5.6 looked about right to me.

Getting home I dropped the snaps in iPhoto and, sure enough, the original at f/5.6 was right, the other two stops underexposed. What gives? Well, I had cranked up the brightness of the Canon’s screen to maximum in a vain attempt to make the thing visible in daylight. As a result, everything looks over exposed. So I have now reset the screen to the factory default.

The picture above is about half the original, yet is wonderfully well defined on a 13x enlargement. So those magicians at Leitz Wetzlar had it all right some forty years ago when this lens was first sold. A 40 year old lens on a 4 week old camera…. OK, so it’s not auto-anything, but I mostly use long lenses on landscapes, which tend to be fairly stationary beasts. I’ll leave sports photography to those far more expert than I will ever be. Or want to be, in that genre.

As for that LCD screen, I have adopted a one hundred year old technology to solve the problem. Diving into my 4″x5″Crown Graphic kit, I borrow the well worn black T shirt which I use to see the focusing screen on that behemoth and stick it over my head and the camera. This actually makes the LCD screen visible. Some things never change.

On the way home I spotted this gaggle of $1mm homes perched on a cliff overlooking the Pacific. Anywhere else these would be slum dwellings but here in California these are considered luxury weekend getaways. Right dead on the San Andreas fault.

Whatever you think of the architecture, you may agree that this old lens still does the job.

Here’s the center section at a 30x magnification ratio:

Leica or Leicaflex lenses on the EOS 5D

About the time I was ordering the Canon EOS 5D it dawned on me that it would be nice to be able to use my Leica Telyt long focus lenses on the digital body. I have a 200mm f/4 which is quite decent and a 400mm f/6.8, the one with the trombone focus action, which is very good. Both were made for use on the horrid Leitz Visoflex mirror housing for the Leica M body, but I had been using them on my metered Leicaflex SL SLR (now sold) with a Leitz M to R adapter, code 14127. I finaly got around to selling the Visoflex, but it wouldn’t go without kicking and screaming, as the first eBay buyer was a certified retard who decided he didn’t want to pay. How do these losers get through life? Mercifully, eBay recognized this nut for what he is and deleted his slanderous, retaliatory feedback. A small nod in the direction of decency and honesty!

Sniffing around the internet, it became obvious that there was quite a number of adapter manufacturers who promised that Leicaflex lenses could be mounted on an EOS body. Prices ranged up to some $200. I bought one from Kiev Camera in the USA for $50, but promptly had to return it as it had a faulty lens locking pin. The folks at Kiev Camera sent me another one and that one works really well.

As you can see, the order of events is Telyt lens, M to R adapter and then R to EOS adapter. The 200mm Telyt shown here, being a truly ancient design, also has a Leica screw to Leica M adapter, # 14166. Despite all these adapters, the whole thing feels rock solid once assembled.

While the Telyt lenses are manual, indeed the 400mm does not even have preset stops, use is easy with the 5D on aperture priority. Indeed, that’s the only way you can use it as the camera has no idea what is fitted, as there are no electronics to feed it the information. So you set the shutter and the camera choses the shutter speed. Focusing is also manual, as once again the lack of electronics defeats the focus confirmation light ordinarily seen in the viewfinder. No matter. The standard screen in the 5D works just fine with these long, slow lenses. For this very occasional long lens user the setup suffices, even though Rube Goldberg might be proud of the design! Both lenses preserve full focus to infinity with this arrangement.

You can see some snaps taken with this combination here. For results with the magnificent 400mm Telyt, please click here.

But wait. The plot thickens. In going through all my gear trying to sell anything that was no longer used, I came across a near new El Nikkor 50mm enlarging lens which I had last used in those mercifully long past, dreary darkroom days. That would be 29 years ago. As any Leica user will tell you, sooner or later you end up in adapter hell, as Leitz made adapters for seemingly everything. They must love the art of machining in Wetzlar and, indeed, their adapters are things of mechanical beauty. The El Nikkor uses a Leica thread mount. A few seconds later and it’s converted to Leica M bayonet with an adapter from the dark recesses of the cupboard where all my remaining junk hides. A separate adapter, # 16596 if you must know, converts my old Leica Bellows II, another remnant of the Visoflex years, into Leica M mount. Attach the M to Leicaflex to EOS adapter on the back and you have a free macro lens:

This gives larger than life images and, of course, infinity focus is not possible. Still, have you tried to sell an enlarging lens recently?

A better use is with the superbly sharp 135mm Leica Apo Telyt lens which gives images 2/3rds life size and also affords a far greater lens to subject difference allowing for better illumination of the subject. Nice to give these old warhorses a new lease of life.
