As a lot of you will know by now, I do a lot of archaeological air photography. A private pilot has recently offered to take pictures for me at times when I can't fly and I want to lend him a fairly decent film camera in preference to his own less than brilliant 4MP digital. I offered an old EOS 650, but he thinks it too big, but is prepared to take something like my Canonet QL-17 GIII. I'd lend it happily, but the 40mm lens is a bit too short to give good images of small features from 1500 - 2000 feet. Can anyone suggest something like this camera: a compact rangefinder with a good, fairly fast lens and shutter priority auto, but with a slightly longer (more 50 than 40mm) lens and a maximum shutter speed of at least 1/500th? I'd prefer a rangefinder, but auto focus would be OK so long as you can switch it off and still focus on infinity (from the air everything is at infinity, except bits of the aircraft).
