Canon FD 70-210 Ghost effect?
1

Hi everyone,

I recently bought a Canon FD 70-210 on eBay. After testing out the lens, I noticed that my recordings have some kind of weird bleached out spot in the middle. Strangely, this spot disappears after zooming in. If I had to make a guess, I’d say this effect appears between 70-100mm.

Could anyone explain to me what causes this artifact? I’ve added a video below.

(I use the lens on a camera with an MFT sensor)

Thank you
