Contax G2 - troubles with biogon 28 f2.8 ?

[piero_piero]

Hi all,

I've just bought an used Contax G2 with 28 + 45 + 90. I am very happy

with my new G2 but I think the f-stop ring of my 28 is too hard to

turn. Sometimes it's hard but sometime it's ok. I didn't realize it

when buying but the seller told me he almost never used the 28. The

lens looks quite ok with none stripe.

 

What do you think about ? Is it possible for a f-stop ring to become

hard to turn with no use ?

 

Thanks for your answers;

Most lenses today use one or more small ball bearings to control the click stops on the aperture scale. If the ball bearings have slipped out of position, then that MIGHT make the aperture scale tough to turn, depending on where the ball bearing is now.

 

Or it might not have anything to do with this, and it could be a different problem altogether.

Piero,

My Biogon 28mm has had lots of use over the last year and the aperture ring is as smooth as silk. Sorry to say it but yours sounds faulty. Good luck with the return or repair.

thanks for your answers.

45 and 90 are quite ok. For the Biogon 28mm, I will use it for the moment and see what happens. Maybe the aperture ring will become smoother. If not, repearing ... :(

I agree with the other replies: it sounds like a fault. But as long as it works I wouldn't worry

too much. I have almost all of the Contax G-Lenses and the aperture ring 'feels' the same

on all of these lenses.
