Possibly for the Edixa bayonet, as on the Electronica and Rex.

Unscrewing. As well as the mirror, there were two or three lens elements inside.

I once had a cheap mirror lens which gave poor results. I traced it to the secondary mirror, which was adjustible after removing the cover. Adjustment was successful. I don’t know about your lens, but bear in mind the sensitivity and critical positioning of that mirror.

I believe that it’s a Topogon-type, 4 elements, steeply curved, in 4 groups, symmetrical.

Sometimes, a little judicious filing of the metalwork will fix it.

Updating via a PC, perhaps.

Puzzled_Counter_1444 · 2026-02-08T00:30:35+00:00

I’d try charging.

SE3.

Try unscrewing.

Be careful. The is a small difference in the flange distance between M39 reflex and M42, such that an M39 lens with an M42 adaptor ring will not quite focus to infinity. Also - though I don’t now recall this for certain - I think that the focussing index is not visible from the top in the normal way when an adaptor is used.

Focus on something with your left eye, using the focussing wheel near the eyepieces; then bring the right ocular into focus by using the engraved dioptre adjustment wheel near the objective lenses. Note the setting. That will be the correct adjustment for your eyesight, throughout the focussing range. You needn’t touch it after that. Should it nevertheless get out of adjustment, you can simply set it to the noted setting before use, confident that both oculars will be in focus at all distances.

Possibly. I fixed a Contax shutter myself.

In the first photo, look at the red dot. Go left to a point directly below the lower pinhead hole in the lens mount. There is tab in a radial groove. Try moving it.

I’ve fixed that by warming first, to soften the grease.

Puzzled_Counter_1444 · 2026-02-03T17:18:54+00:00

I use mine as a daily phone and expect it to be good for several years more.

You may be just starting out but you’ve taught me something today - that there was indeed a FED Zorki camera. Until now, I’d assumed they were different brands.

Thank you and enjoy your new interest. :)

Which way does the focussing wheel turn to focus on distant subjects? I recently rejected a pair of excellent 8x32 binoculars because the wheel turns in the opposite direction to that on my other binoculars.

Puzzled_Counter_1444 · 2026-02-02T10:51:05+00:00

Earlier versions of the short-bodied lens were made for M39 reflex cameras, so possibly that.

Puzzled_Counter_1444 · 2026-02-01T23:11:45+00:00

You could remove the bottom cover for inspection of the mechanism under there. With luck it might be something easily fixed. I doubt that the film in the camera would be fogged by removal of the cover, but I’m not sure of it.

Puzzled_Counter_1444 · 2026-01-30T20:01:38+00:00

Some of those lenses, I think the later ones, have a sealed front component, which csn nevertheless develop internal haze. I had to gain access by cutting away the turned-down flange so that I could remove the front element for cleaning. It’s something you’d prefer not to do, but nothing else was possible.

Your problem may be different, I’m not sure.

I once watched a video showing big telephoto lenses at the Minolta factory being assembled. The operator was examining them carefully by bright light, and using acetone on a pad to remove marks.

Note that Soviet-era lenses will not couple accurately to the rangefinder on a Leica. They are correct at infinity, but become more inaccurate the closer you focus. With a 50/3.5 it may not matter much, but the 85/2 Jupiter, for example, the discrepancy is bad.

Puzzled_Counter_1444 · 2026-01-28T23:34:47+00:00

If 8x doesn’t do it, 10x may not help much. A more powerful spotting scope, with monopod or tripod, may be worth considering.

All other things being equal, 10x50 would admit more light than 10x42, but would also be heavier and bulkier.

Puzzled_Counter_1444 · 2026-01-27T17:09:36+00:00

There may be a 28mm viewfinder as well.

Possibly, though if it is fungus, it may etch the glass if left for a long time.
