So everybody knows about the 1.6 and 1.3 crop for smaller censors.

What I'm proposing is that the focal length doesn't actually change so you quite clearly are not brought closer to your subject. And your image is not actually cropped as per say but this is the best way to explain it really.

This is really what I think, your angle of view thru the lens is actually less. So if 35mm is supposed to give you a view of 90 deg on a full frame, on an APS is is reduced to 60 deg. Hence the feeling of wanting to say its a 58mm.

I just feel it's wrong to call it a different focal length when your subject is not actually in all realist brought closer to the frame but it is simply 'viewed less'...

What do you think?
