here is an interesting thread I put up on photo.net awhile back about the Kodak Pony 135 with some sample shots and some interesting discussion that followed about the quality that such a modest camera was capable of.
I had bought the Pony in a complete package of manual, bulbs, flash head, camera and case from a Antiques Mart south of Barrie Ontario for if my memroy serves $25. the zone focusing was no problem. in the thread there are shots followed by a kind of full scan zoom in section to show detail. Pretty good results.
Sadly the cat in the shots passed away at age 17, he was my little zen master, the Sundance Kid
