The photos I brought to our meeting were made with two brands of cameras, three brands of lenses, both film and digital. No doubt there were aesthetic factors involved as well, but the prints he selected for the gallery were all made with the DMR, all made with Leica lenses (mostly the 280mm f/4 APO). Steve Appel might only represent 0.000001% of the population, but he represents the portion of the population I'm marketing to. > You can buy NINE Nikon 50mm f1.4s for the price of one 50mm Summilux and > 99.99999% of > the population of the world would be unable to understand any > justification you may care > to make for that, particularly when the difference in resolution is > difficult to detect > on ultra fine grain film let alone a digital sensor. The cost comparison is meaningless unless the two lenses perform exactly the same. If only one lens meets my needs, it doesn't matter how little the alternatives cost. Even if resolution and other optical properties were identical (they're not in my experience), ergonomic factors often make the difference between the photo I wanted and one that is 'pretty good but not quite'. For example, the tall tripod foot on many long lenses: an ergonomic disaster. The tall foot not only makes a longer moment arm for the camera's vibrations, but it also prevent the left hand from supporting the lens while using the focusing ring. With this kind of lens I found I had to use faster shutter speeds than with a comparable Leica lens (short tripod foot) for equivalent lack of camera motion blur. Another example is viewfinders: the typical DSLR viewfinder has numerous focus points, which if the subject's eye and the active AF sensor coincide (and the sensor is functional and accurate at f/4 or smaller aperture), all is well. However my subjects are frequently all over the viewfinder with the plane of optimum focus changing from one moment to the next as the creature shifts its weight, scratches an itch, grabs a snack or reacts to an unexpected sound. Focus-lock-recompose doesn't work at the narrow DOF I'm often encountering (even Canon recommends against this technique) so my choice (as Canon suggests) is to focus manually at any point on the viewscreen or alter my composition to suit the camera's focusing aids. I've chosen to focus using the entire viewscreen and a camera optimized for manual focus. Doug Herr Birdman of Sacramento http://www.wildlightphoto.com
