I should know this but I don't. I have heard people talk about it but I don't understand the difference between a DX body and a FX body. Which cameras have the DX and the FX body? Thanks!! :smile:

the sensor size on an FX is a full frame (ie same size as 35mm film) wheras a DX is smaller, so you get a cropping effect... with this effect the lens length changes... on nikon DX bodies its a factor of 1.5 sooooooo... a 200mm len on a DX body will give a focal length equal to a 300mm on a FX body

the FX... is the full-frame sensor... the same size as a 35mm camera the D700 and D3 are the only NIKON cameras with a full-frame sensor, AT THIS POINT DX... is a smaller sensor more data crammed in a smaller area... all other nikon DSLRs are DX-sensor based
