Rangefinder Sonnar 1.5/50 on EOS 5D, lens of late 40s or early 50s, used with hand on a M39 adapter and a protection of tin foil around the base of lens to stop light coming from the hole:

First a series of four, progressive from stopped down (not completely) to wide open:

1

2

3

4


a bit stopped down:

5


now two, one a bit stopped down then wide open:

6

7


another two, first stopped down then wide open:

8

9


Finally Melissa, wide open:

10



Used (necessarily) as a macro, I would classify this lens as "Impressionistic", definitely at wide open, but also down to about f/5.6 or f/8. This of course depends from the extreme proximity of the subject.
WHen most or fully stopped down, the lens reveals itself as very sharp.

Yes, the Jupiter-3 is the Soviet replica of this lens.
The oldest exemplars are likely to be made with original Zeiss components stolen from Jena.

Stolen from me you mean Crying or Very sad I want that lens (and a Contax III for the matter Razz). So lenses for the Contax rangefinders are in M39 mount, that's interesting (I'm waiting for a Zorki Is to come).

No, they have the Contax bayonet. I used a M39 adapter to reduce the surface of the hole of the 5D.
The base of the lens is very tiny - it's like half of the front lens and if you consider that the front lens has a diameter of (I think) 40mm more or less...

The russian copy, the Jupiter-3, was made on both, Contax and LTM mount.

True. If someone is interested in an impressionistic macro lens, can buy a J-3 with a M39 adapter. The total cost should be below 100 Eur.

My advice is to not get a M39-M42 ring, because if they are screwed tight into either the adapter or lens, they will never be removed. Better invest in a M39 adapter directly. You spend a little more, but you have a normal adapter that you can take easily on and off without cursing all the saints in the paradise Wink

Is there an SLR (registration ~ 45 mm) version of this lens ? From what has been said I guess that there isn't.

Nope and it was never been done because of the physical limitations of the Sonnar scheme, at 50mm the rear lens would hit the mirror in a SLR, so they had to use the Sonnar scheme just for teles.

Thanks for the explanation.
