Correcting for infinite focus on Rollei 50mm f1.8 HFT Planar lens

Ғылым және технология

A common problem fitting conversion adapters to SLR cameras is that sometimes infinite focus is not possible to achieve.
I will add that not all lenses are as simple to correct as the Rollei, indeed some are impossible.

    Thank you so much - that was an excellent advice! My Sonnar 2.8 85 now works on my Sony A7II as it should.

    Interesting film. If I remove the focusing barrel , I suppose that I could relub it. Is that the reght process ? Thanks

    Thanks for the video. Stopping down could also give you infinity focus.

    Indeed, But it's nice to have the wide aperture option at infinity.

    Hello! Smart solution! But can ask you, do you have any information about possibility to mount this lens to FF Canon 6D? I see that rear lens significantly protrudes when lens is set on infinity. If the rear part of lens can hits the mirror of camera? Thanks!

    I might well be very close to the mirror , but not sure if it would impact. I know the efs lenses can touch and i don't think it extends that far.

    Viktor, yes it will slap the mirror on a 6D. I have it with M42 mount, and it is an issue. Your best bet is it to use it at close focus only thru the viewfinder, or you can use it on Live View mode only to avoid mirror contact, where it should also hit infinity - more or less. Even with this issue, it spends a lot of time on my 6d. It is an exceptional lens.
