Close enough for my needs: For Me, this is a very useful stat for lenses. As a thumb rule---this is slightly larger than awaist up portrait, so when determining if a lens would suit my needs I look at the distanceI would have to be away from the subject to achieve a waist up portrait. So, on a 7d with a 135 F2l, I need at least 24 feet (15.42x1.6) to get this approximate framing, Less if I am doing a head shot.


Is my logic correct?





Thanks
