This is a great user in excellent condition. Some paint loss on the finish, but nothing serious. It comes with the original caps and case. Focusing is smooth but a little dry (no surprise, eh?) and the diaphragm is clean and very snappy. There's a very small ding on the front ring (you can see it in the photo).

The only other problem with this lens is that the diaphragm does not open completely at the f/3.5 setting; it's closed just a by a very tiny amount (this is a f/3.5 lens, I think it becomes a f/3.55 lens this way Smile)

All in all, a great user. Price: 60 Euros, shipping to anywhere in Europe included. Elsewhere please ask; PayPal please add 2,70 euros.

If by this you mean that just the very edges of the aperture blades remain visible, I think it's normal for this lens; mine does it too.

Interesting, maybe our copies were made by the same DDR comrade Smile Thanks for your reply!

I consulted this issue with my repairman some time ago - he showed me on the testing device, that if the real amount of light should be equal to f/3.5, the lens should be adjusted in this way. If he ajusts the aperture to be fully opened, the amount of light is higher than it should be at f/3.5.

It is realted only to MC 135/3.5 Sonnar.

Thanks for your comments, Jiri. It must be said: the CZJ lenses have interesting quirks I was not aware of. This is a great forum, I always learn something new!

@Milano: PM replied! Very Happy
