Adapting Canon FD lenses


Recommended Posts

I quiet often use Canon FD lenses for filming with my BMPCC. It's not brilliant but gets the job done and a M43 to FD adaptor was easy to find and works quiet well.

 

I was recently going to try and use the FD lenses on my Bolex EBM (super 16) so I ordered an FD lens to Bolex Bayonet adaptor. However, it has no mechanism to affect the aperture control lever inside the lens. Has anyone dealt with one of these before? Is there something obvious I am missing?

 

I guess my option is to machine something up that holds the manual aperture lever in for me? Thats the only way I can manually set the aperture on the lens.

 

I'll try and attach some photos to demonstrate my question.

top on is FD to M43 and works well because it has the mechanism to hold the arm in.

bottom is FC to bolex bayonet and it doesn't have the same mechanism.

 

thoughts?

 

throw it in the bin?

bah. my apologies ... did another search and found this thread which is slightly helpful. i didn't realise how much easier it is to google things on this forum than use the internal search

I used to shoot with a ton of FDs on my DSLRs. Great for the price, but the ones with a real price saving difference are so soft you can't mix them with other sets. I've actually wondered myself why the aperture wouldn't change when I rotated the iris ring.

 

Nevertheless, love the external materials for the price.

You need to make a little 'widget' that you push open the lever with. At its simplest it can be a toothpick or section of q-tip but its better /safer to make something that will stay in place. Have done this many times. Don't chuck the lens, FD lenses are great, especially the L-Series.

The lever is fairly strongly spring-loaded so it would need to be quite robust.

If you are confident with a drill you could drill a hole and insert a tight-fitting metal peg. A bit of bicycle spoke would do.
