Well, I just received the 55mm Auto ... and there was oil in the lens barrel when extended (it almost dripped out).
It was clearly a junker that someone bought cheap, re-furbished, and tried to pass for a 'mint' version. (Should have known by the smaller pictures than usual.)
One interesting thing came out ... it felt a little lighter, and less sturdy, than the 55m-P-Auto ... which came out later.
Anyway, I may wind up keeping the P-Auto because it is such a clean copy and they're cheap enough.
I typically don't keep anything I won't bring with me 70% of the time though, as I am not a collector.
This will be a good, lightweight choice to bring with me to work as an investigator, as many times I have to photograph wounds, or material damage, and don't need to bring the CV 125, and don't need bokeh, but would like very sharp resolution.
