Ergonomically the outfit handles unbelievably well and, mercifully, there is no wobble despite all those adapter rings.<\/p>\n<p>I had the 5D set on &#8216;Av&#8217;, 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:<\/p>\n<p><center><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/www.pindelski.org\/Blog\/StormS.jpg\" width=\"681\" height=\"1014\" alt=\"\" \/><\/center><\/p>\n<p>I checked the screen preview on the 5D&#8217;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.<\/p>\n<p>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&#8217;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.<\/p>\n<p>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&#8230;.  OK, so it&#8217;s not auto-anything, but I mostly use long lenses on landscapes, which tend to be fairly stationary beasts.  I&#8217;ll leave sports photography to those far more expert than I will ever be.  Or want to be, in that genre.<\/p>\n<p>As for that LCD screen, I have adopted a one hundred year old technology to solve the problem.  Diving into my 4&#8243;x5&#8243;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.<\/p>\n<p>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.<\/p>\n<p><center><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/www.pindelski.org\/Blog\/MorroBayS.jpg\" width=\"1014\" height=\"681\" alt=\"\" \/><\/center><\/p>\n<p>Whatever you think of the architecture, you may agree that this old lens still does the job.<\/p>\n<p>Here&#8217;s the center section at a 30x magnification ratio:<\/p>\n<p><center><img decoding=\"async\" src=\"http:\/\/www.pindelski.org\/Blog\/MorroBayDetail.jpg\"><\/center><\/p>\n","protected":false},"excerpt":{"rendered":"<p>That&#8217;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.
