Bonjour,

I bought this lens over a year ago on a LBA whim ... it had very oily blades that would seize and/or move erratically. Finally found the time to clean ... my first endeavor here and it took some time, but learned a lot.

First post cleaning tests look promising and I'll conservatively rate as a "7" across the board with the promise to test further once the bright sunny spring weather arrives ... indoors tests seem "OK" for their limited extent.

Allez et à plus tard, John le Frog

Below are additional photos of this lens ...
