Greg's Mustang GT
Nikon D100, Nikkor 24mm f2.8 AF
My good buddy's Mustang GT. We went for a fun drive one day, up north as far as Calistoga, then west to Bodega Bay, then back south. I took him here in the Marin Headlands to get some shots of the car. This is my secret car photo spot.

Warren,
Nice shot of a nice car. I like the perspective of the shot. This shot reminds me of a question that I have been thinking about for some time now.
When we use film lenses on our cropped sensors, it seems to me that the old wide angles like the 24mm used in this photo will still provide the wide angle perspective (i.e level of compression/perspective distortion) that we had using film, just with a smaller frame area and more normal field of view. Is that correct? If I am right, the normal focal length for cropped digital (about 35mm) will yield a normal field of view but a wide angle perspective in terms of compression/perspective distortion. What do you think?
That leads me to my last question. The even smaller sensors use very short focal length lenses like 7mm on my Canon s500. how do they maintain normal compression with a lens that short?

Thanks Steve.
I always get a headache when i think too hard about crop factors, field of view, and perspective, etc. :).
You are right in terms of field of view (35mm is on a dslr is roughly equivalent to a 52mm fov on a 35mm film camera).
Perspective is purely a function of the relationship between camera to subject distance. In the case of this picture for example. If I had a 35mm film camera with a 35mm lens attached to it, and I compose the shot so that the car is the same size in the frame as this shot, the apparent perspective would be identical (to my 24mm on a the D100).
That's my non-technical explanation of this. I hope it makes sense :).
I just did a test. I had my 50mm lens on my Nikon F3hp, and my 35mm lens on the D100. I aimed the cameras at an object and framed it to the edge of the viewfinders in both cameras. I was just about the same distance from the subject with both cameras, and the perspective appeared identical (if I had taken the pictures, the two imnages would be identical).
This is why I have been using my 35mm manual focus lens on my D100 so much lately. I want a "normal" lens for my D100, but I don't really want to buy another 35mm lens (i already have two mf versions).
