[QUOTE="bandit993, post: 442778, member: 16598"] I was told that an fx lens on a dx body was 1.5 times the focal length. So a 200mm fx lens is 300mm on a dx body. Is that correct? But what I tried today slightly disproved that. I have the sigma 70-200mm f/2.8 lens. I also have the Nikon 55-300mm f/ 4.5-5.6 lens. I took a picture of an object from the same spot with both lenses at full zoom. I found the 300mm picture to be a little closer than the 200mm one. I shot both at F/8 with the D5200 . Anyone else ever tried that? I would say that it seemed more like 1.4 crop factor. I may be wrong or missing something but just wanted to mention it. Thanks [/QUOTE]
