I think it really interesting to get the views of such a diverse range of photographers. As a bit of background I'm now in my early fifties and when I was asked to leave skool I worked in a central London camera shop for about 3-4 years before becoming a working photographer ever since. Working in the shop gave me the chance to use pretty much all the 35mm systems that were around at the time. In the end I plumped for Nikon and have stuck with it ever since. At the time the fact that the FE/M/2's had both aperture and shutter speed in the viewfinder was a big factor for me.
I have always found it interesting the reasons people make that initial commitment to a system. A friend of mine said in the late seventies he would of chosen Nikon FE's but because the meter is turned on by putting the winder on lever into the stand off position and he's left eyed he would of had his own thumb in his right eye. So he bought a Canon. When I worked in the shop I sold a man a camera who was so crosseyed that he put the camera viewfinder on the bridge of his nose !!
I always had a soft spot for the OM's Minolta XD7 & XE1 and pentaxes but nikons did it for me personally. I've now had F2,3,4,5's FE/M FM2 FE2 F100, D2X,3,4s
I've got 4 young adult children and they all shoot film none of them seem to want AF cameras. I think the tactile quality of the manual focus generation of cameras is very appealing to the digital generation
