[QUOTE="BackdoorArts, post: 159061, member: 9240"] It would actually be a 66mm lens on a DX (to get from DX to FX divide by 2 and add that to the original focal length). There are 2 ways of looking at the question... Method 1: Both cameras have the same lens, so in order to take the exact same photograph you have to stand further away with the DX camera than you would with the FX camera. The increased distance from the subject also increases your depth of field...

The different lenses will produce different DoF at the same apertures. [IMG]http://tonycorrea.com/blog/wp-content/gallery/posts_misc/85dxvs135fx_wp.jpg[/IMG] [/QUOTE]
