Summicron-R 50mm upgrade to 3 cams

Hi,

I have documented the "upgrade" that I've done to my Leica Summicron-R 50/2 from 2 cams to 3 cams: https://tertuliadelmanuela.wordpress.com/2021/01/13/leica-summicron-r-50-2-upgrade-to-three-cams/

It's quite an amateur work, but I think it could be interesting to the people using the R system, specially for understanding a bit more how the 2nd and 3rd cams work, specially considering the lack of information about it in the net.

Of course, any comment/feedback is absolutely welcome.

Best regards and stay safe,

Augusto

Well done! I converted my Summicron 50mm R cam to 3 cams to use on my Leicaflex SL2 as well as my R4S, and used the Elmarit Macro mount as you did. I ended up filing the cam a hint at a time (you can take it off easily enough but you can't put it back), and all the holes were there already. I am not very good at any form of precision DIY, so I was very pleasantly surprised at how easy it was.

That's great to know!! So the addition of the first and second cam is also possible and easy using the Elmarit Macro tube!! Thank you.

Hi everybody!

My name is Marco from Italy and I need to modify my lens Summicron 50/2 with 2 cams in 3 cams.

I've just read the interesting post of Tranquilo67 and I want to made the same modification. But I don't understand what kind of mount of the Elmarit 60 I've have to buy... and where to buy it. Somebody could help me?

Best regards

Use the 3 cam extender for 60mm f2.8. The 3 cam is designed for f2.8 you need to find a 50mm f2 3 cam to measure the size and file off the extra.
