Just finished printing a shot taken with an ancient Monitor. Wow! I'm extremely impressed. Granted "at f-22 all lenses are great", but these shots look really good. Very sharp with much better local contrast than I would have expected. I cleaned the glass, cleaned the shutter, patched the bellows leaks with fabric paint, and loaded it with Efke 25 and I have to say that some fairly serious photographic horsepower you can put in a pocket. 25 bucks.

the two lower right hand pics were done with this combination. The files you see are scans from the neg. The prints look much better.
