[QUOTE="Woodyg3, post: 424598, member: 24569"] J-see, from the very link you posted with the macro depth of field calculator: "Depth of field defined based on what would appear sharp in an 8x10 print viewed from a distance of one foot" The 1:2 shot would have to be printed at FOUR TIMES the size of the 1:1 print for objects to be the same size, that's where you lose depth of field. If this weren't true, we could take an f/1.8 shot with our trusty 50mm lens of a flower 20 feet away, crop the picture and have the entire flower be in perfect focus. It just doesn't work this way.
