35 GT Aperture problem...please help.

[j_r_bernstein]

Hi everyone,

 

I've got a Minox 35GT with a "slow" aperture. That is, when I open up the

aperture, it moves very slowly (when it moves at all) and often stops well

short of wide-open.

 

I'm pretty sure that I can see some oil on the aperture leaves, but I have no

idea how to get at them. I've taken off the focusing ring, hoping that the

front element would be removable from there...but it wasn't (that I could see).

 

Do I have to get at it from the back? How *does* it open? Anyone have a

service manual?

 

I don't want to take it to be serviced, as that will cost me the price of an

other second-hand 35GT, and I don't mind doing it myself.

 

Thanks very much for your help!

Jordan

Lighter Fluid (Ronsonal) may help in removing contamination, as a last resort. Regards.

Thanks...but HOW do I get the lighter-fluid on the aperture?!?

 

My problem isn't what to use to clean it, it's how to get at it.

 

Thanks.

Assuming there is no mechanical failure in the aperture adjustment mechanism, some fluid placed around the external adjusting ring while moving it back and forth might "do the trick". Regards.

And as a first resort? ;-)

@j r bernstein did you find a way to get inside the lens ? I have an almost mint Minox 35 GT-E but the Aperture ring

doesn't make the blades go open and closed.

 

I hope I can fix this myself any info on getting intonthe lens would be great.

 

Happy shooting and a fine weekend
