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 plus tard, John le Frog

Below are additional photos of this lens ...
