Hey wjk :) Thanks a mil. I’m using a Nikon D200 at the moment with the 18-70 lens. In studio i tend to meter for f11 for portraits and for that lens it works pretty well to give a greater depth of field and keep everything in the frame as sharp as possible (need we discuss the circle of confusion :shock: ). f11 isn’t going to be the sweet point in every lens but a general rule for me is never to go past f16 in studio. I shoot RAW too so my images require a bit of sharpening.
