shower thought: If you think about it, the contaxRF mount is technically the easiest mount to adapter other lenses to because the focusing helicoid is already on the camera!

so this is the result of it, M42 to contaxRF adapter

Currently have a hankering for Nikon DE-1 plain prism for F2...

I just bought an early, Made in Germany, ROLLEI 35 in as new condition. Other than all of the slow shutters behave like BULB.
2, 4, 8 and 15 all behave the same as B.
From 30 onwards it seems to be working fairly accurately.
Is this something I can address at home with some basic tools or do I need to go looking for a repair shop?
I'd appreciate any help...

I am awaiting delivery of a Tokina made Vivitar that has 5 elements in 5 groups.

Could someone share with me what type of lens this may be? Is it a Heliar formula? Would this relatively low element count excel at low light?

Lastly, which sites are best for researching the various formulas and their history.

Thanks

Greetings all,

I was in the process of selling this lens when the buyer pointed out there's a screw missing from the aperture ring.

Can't see it being difficult to replace the missing screw with the appropriate screw driver, so has anyone got idea where I can find one or know the screw size or type?
