Rafael's post about effective focal length shots thread has my brain twisting once again.
My M4/3 G1 has a crop factor of 2x so I think that means it has a reduced field of view compared to a 35mm film camera. I do not see it meaning a 50mm lens will have the magnification of a 100mm lens only the view of one . The way I see it, a 50 is a 50 but with a reduced field of view on a crop factor body. The adapters we use set the lens to focus on the sensor as though it was film i.e. the same offset as it would have on a film camera. The camera body is not changing the focal length of the lens. Am I incorrect in my thinking?
