Screw-in eyepiece / correction lens tend to become loose

[Samoreen]

Hi,

I can confirm this problem which has been already noticed by others. I lost my correction lens on a small trail where a lot of people were walking and riding bikes. I had luck because I found it again on the way back, in the middle of the trail, after about 15 minutes. Intact.

Another problem are the lens caps of the Zeiss lenses which are prone to be lost one of these days (no doubt that this will happen). This is the worst cap system that I had to use until now.

Otherwise, I like this camera very much, although the shutter speed LED display is too often hard to see and too far away on the left of the viewfinder.

Would surprise me if it is not exactly the same thread and size of the R-D1 and Bessas. In which case I can confirm it is very easy to loose them on the run, no matter how much you keep on tightening them.

Eyepiece correction: how about a dab of Loctite?

Zeiss Ikon lens caps. Very true. From http://www.rogerandfrances.com/subscription/zeiss.html

Lens caps -- the worst feature

The lens caps are of the 'pinch' clip-in type and are fiddly and easy to drop. The really bad news is that the ridges that should make them easier to grip are moulded in the wrong direction, parallel to the optical axis instead of at right angles to it. Several times we dropped them, and it was pure luck that none went down a drain or over a wall. However, if one is going to have a 'worst feature', this really isn't too bad. They can be fitted and removed (with difficulty) with the lens hoods in place.

Or from the 18mm Distagon review, http://www.rogerandfrances.com/subscription/reviews 18 zeiss.html

A lens cap adds about 6mm or 1/4 inch to this -- the usual poisonous, easy-to-drop pinch-grip type

Or from the 1,5/50 C-Sonnar review, http://www.rogerandfrances.com/subscription/ps firstlook sonnar 50.html

The lens cap is the standard, truly horrible ZI/Voigtländer pinch type, which jumps out of your fingers at the slightest provocation and can easily break once you drop it: we've lost two to breakage, over the range of ZI lenses we've tested.

I hasten to add that the horrible lens caps are our ONLY real gripe with these lenses, both of which Frances and I like very much. Even so, we use Op/Tech HoodHats with them: http://www.rogerandfrances.com/subscription/review optech shower cap.html

Cheers,

Thanks. However, I'd like to be able to switch to the standard eyepiece : I can use the 50mm lens with my glasses but when using a 35mm, I have to shoot without glasses and with a correction lens.

Try clear fingernail polish for a easier to remove bond, but MUCH better than Loctite for easier removal.

There are various grades of Loctite, some MUCH weaker than others. Weaker, I suspect, than nail varnish.

Counterintuitively, a tiny amount of thick grease can sometimes increase the resistance of a thread to vibrating loose. As can a tiny dab of spittle (yes, gross, but those damn' things are EXPENSIVE).

Cheers,

R.

The rubber edge on my eyepiece is wearing out. Does anybody know where replacements can be had?

The eyepiece is identical to that on the Nikon FM-10, which Cosina also built. Most camera repair guys have a stash of FM-10s which they use as parts cameras since few are economically repairable.
