I picked up another FX-3 Super 2000 at a swap meet recently and was disappointed to find that the mirror hits the back of the lens. The lens is an ML 50/1.9, and the mirror touches the back of it and hangs there at any distance setting between infinity and about 7 ft. Below 7 ft. the mirror completes its cycle. Someone told me the cement holding the mirror in place had softened, allowing the mirror to slip forward slightly. Could that be true, or is it a problem in the mirror actuation mechanism?

I'll receive a camera with the same problem in about a week. I'll be glad to talk about it then

Excellent! Let me know when you've had a chance to look at yours.

Someone told me the cement holding the mirror in place had softened, allowing the mirror to slip forward slightly. Someone was right. In fact, this is a well-known issue with many Contax and Yashica SLRs. I would advise you to wait for a warm, sunny day, expose the cam to the sunlight for half an hour or so, then gently try to push the mirror up again. At least that's how it worked for me. Some repair instructions on the net also suggest using an electric fan to warm up the mirror unit. Michael

same problem with my FX3 Super and FX-D. Put speed dial in Bulb and press shutter. whit mirror up, use hairdriyer to warm the glue, and gently push the mirror in original position. now release shutter and put your camera on the back in a cold place for one night.

Sorry, hairdryer -- not fan -- is the correct word, of course. Thanks, Doc, for this clarification and your further hints.

I was afraid that might be right. It was a warm day when I first noticed the problem. Unfortunately, I live in central Florida where they're almost all warm days, so I suspect this may be a recurrent difficulty. And word that the FX-D might show the same symptoms is discouraging; I have one in the mail to me.
I wonder if a change of cement type might be in order.

IMHO, not simple to change the glue ...mirror it's prone to brake and, when removed, the carrier must be cleaned thoroughly (the surface must be perfectly plane). Otherwise, when you paste mirror with new glue, there may be focus flaws. see this diy of contax 139 at "Replacing the Mirror" www.contax139.info/diy

It seems we're talking major surgery, requiring a thin blade and a steady hand. I'll see how the hairdryer works on the FX-3 Super 2K, and I'll keep my fingers crossed that the FX-D doesn't need this kind of work when it gets here.

The FX-D arrived today. It's obviously been used, with some nice brassing on the top and bottom, but the mirror doesn't stick and the meter and shutter seem to be working accurately. Still haven't taken the hairdryer to the FX-3, but it's in the queue.

on FX-D the problem it's more rare instead of FX-3 Super & Super 2000 (made by Kyocera and Cosina)

My FX-D arrived as well. The mirror clearly sits lower by a couple of milimeters. I'll try to push it without disassembly.
I did it as you suggested, although I used hot air soldering station. It has a smaller nozzle - not a particularly necessary feature but makes the repair a bit more controlled. It took me 2 minutes to get the glue soft enough. I pushed it very slowly, not even all the way up, just so much, that it closes, because I didn't want too much strain on the mechanism. I used a small piece of paper not to leave a fingerprint on the mirror. Now it seems fine.

Created an account to thank you guys for your help on this issue! I recently picked up two FX-3 Super 2000s (my first Yashicas), and a Carl Zeiss Planar 1.4/50. The first body had a cracked top plate, wobbly film advance lever, quite a bit of grime and peeling leatherette but worked just fine. The second, almost mint in original box, serial number in the low 5XXXXXXs, and only $15, was having issues. The shutter would fire with the ML 44-75mm kit lens, but became stuck every time with the Planar mounted. Since I had to remove the lens each time to get it to cycle, I figured the issue had to be with the mirror hitting the lens – and sure enough I could see it was crookedly glued in, overhanging by 3-5mm. Following your instructions I had the mirror set properly and working in no time.
I will say this, however – after warming and gently pushing the mirror into place, I noticed a gold/bronze discoloration in one corner of the mirror appearing on the silvered back. This was on the glued side, not a smudge on the mirror surface. I have a feeling that some of the mirror silvering came away with the glue when I moved it, possibly because I overheated (or underheated?) the whole thing. Has anyone had this problem? I notice no change through the finder, so it shouldn't pose any practical issue.
Anyway thanks again, I'm looking forward to getting out with my new piece of kit.

gold/bronze because mirror is laminated. maybe you have overhated..20-30 seconds it's enough

Figured as much. Today it looks like the mirror has slid partway back, would it be inadvisable to use a dab of superglue to secure it? Is there a type of cement I can get at a hobby shop?
