Re: Guessing the DOF scales on the Wife's S100?

Website looks great! I added it to my "Photo Tools" favourites. Lots to experiment with but in a quick trial I set the S100 Manual gauge at the 2.5' Hyperfocal length and ISO 80/f 5.6 and the foreground is sharp beginning at about 1.8 feet but beyond about 12 feet to infinity it still looks soft. It could be sensor imaging limitations? Maybe aspherical lenses do unusual things at smaller aperatures. It may be an optical anomaly, in that the ray trace uses a different path through the aspheric figure and therefore results may be different from spherical figures? I am looking into that tonight.
