Contrast

I lack the courage for 'guess' focus, but there's no doubt, those Perkeos deliver the goods.

Really nice contrast and detail! There's something about the decay of human effort, be it urban or rural, that just begs to be put on B&W.

HiHo, it really isn't that difficult. The later zone-focusing folders like Gerry's Perkeo 2 have the helpful feature of a depth-of-field scale on the lens, so you really have a lot of control over what will be in focus.
