Bought a lens on EBAY, but it didn't work, here's what I did.

This video shows all of the steps in great detail on how to fix a stuck aperture, and an oily aperture so that you can get the full use back out of your old manual lenses.

This particular lens was purchased from a good seller on ebay, the lens was listed as being completely functional, however when it arrived the aperture did not work at all. I was a little disappointed, but decided that I liked the lens and since it only costed $20, I'd try to fix it rather than return it.

I've tried to include every step of the process, including before and after photos! it is a long video so skip the steps you don't feel that you need to see using the timestamps below..

I hope you find the video helpful so that you can can be confident in doing the same repair.

Also, one correction, this lens was made in the 70s.
