Different 50mm summicrons...

[-vin-]

I found at least five different versions of this mithical lens:
-collapsible
-Dual Range
-Rigid
-type 3
-type 4
(according to dcolucci's site)

why don't you tell me what are the main differences between these lenses? could you post some shots that make me notice them?

I think this could be an interesting thread for many...

Stephen Gandy has them covered pretty well on his website: Cameraquest M-lenses

As for the DR, there is even a separate page on it: Summicron 50mm f/2 DR. The DR and Rigid are by most people considered to have the same optical formula but the DR have a more precise focal length (51.9mm).

The optics module of the DR and Rigid are interchangeable. It is the most over-engineered optics module that I've dealt with. The DR cannot be used on some modern M-Mount cameras.

The Collapsible Summicron went through a change early on, the thorium glass was replaced at about SN 1 04x xxx (I forget the cutoff. around that number).

@Emil and Rafael: I've already seen those threads, but there are no pictures in them...

Great lens. Works on all M bodies except the M8. The "goggles" are only required for focusing closer than 1m. Built like a fine watch.

THANK YOU, venchka!

so is it possible that it'll decrease in price, in the future?

Why wait?

Maybe. Maybe not. They are dirt cheap now. Get one and enjoy it.

Yes, it works on M8, but only on close focusing modus. 🙂
