Something that I didn't know until a couple of weeks ago...
Anyone like to guess [ maybe this is common knowledge
Do you get more or less DOF using the same lens with a FF or APS-C sensor with the same "framing" ?
(i.e. you need to walk closer with the FF camera)
Or, if you had an FF camera with a 300mm lens at f4, and a APS-C camera (1.5 crop) with a 200mm lens at f4 (so same focal length), do they give the same DOF, or is one more than the other?
