[QUOTE="BackdoorArts, post: 347572, member: 9240"] This is one of those rules where there is absolutely no difference between FX and DX. Think about it - DX is just the center 44% of the FX sensor, so why would it need a faster shutter speed? The difference is [I]effective[/I] focal length, not [I]actual[/I] focal length. And yes, Dave, it's 1/focal length as a minimum. That said, as the pixel density increases you may need to ramp that up some as you go longer. I'm hearing guys saying things like on the D800/810 they need to go 1/(2-or-3 x focal length). [/QUOTE]
