Canon FD Lens Aperture Lock

A quick follow-up on the “Old Canon Lenses” vlog I posted a few weeks ago…

Those over-exposed pictures really bothered me and I realized that the aperture blades in the lens were not moving when I moved the ring.

Canon FD aperture blades will lock at 5.6 if you don’t manually unlock them or make sure you have an adapter that has an unlocking mechanism. The K&F Lens Mount Adapter does have this feature.

Even though I figured out the issue, I am not sure if these manual lenses are for me. But I am learning more.

This video also has detailed instructions on how to unlock Canon FD aperture blades:

Playing with old Canon Lenses

I found a two Canon FD lenses that I bought on ebay a while ago. I wondered if they would work with my Sony E-mount cameras, so I ordered an adapter ring and started playing around.

The lenses:

  • Canon FD 50MM 1.8
  • Canon FD 35MM 2.8

I took pictures indoors and out, and did some talking head video indoors.

My general conclusion is – while it is nice to play with old lenses, the new technology is far superior and makes life so much easier. You can not self-film/vlog with old manual lenses. I also really needed a ND filter outside.
