Hi, I have recently bought a new nikkor 50mm 1.4g lens, and since reading about it on various forums have been confused by what some people have said. I bought this lens under the impression that using it with my D80 would produce photos similar to what the eye sees - similar focal length etc. But I have since been told that with a D80 specifically the focal length would be more like 75mm when using this lens, something about not being full frame? I don't know what means. If this is the case - out of interest, what nikon cameras are 'full frame' and would produce true 50mm photos? Really lost on this one, I hope this post made sense. Thanks in advance.
