the original Ql17 is quite big. It was replaced by the compact model in 1969 or so. The Canon QL17 GIII is widely available, and is compact
Sorry, I thought it was only Canon QL17 GIII, I didn't know Canon QL17 was a different model...
So, if Retinas are more compact and have sharper lenses there is no need to look for a Canon.
Now a few more questions... Schneiders are very good lenses as far as I know. What about Heligons or Ektars? Should I look only for IIc or IIIC?
And last but not least, do they have any other problems except for the week pint in the cocking mechanism?
