Hi everyone - brand new user here. I've been reading the forum for a while and really appreciate all the information and knowledge about rangefinders and photography that everyone shares.

Anyway, I have a problem with vertical misalignment of the rangefinder patch in my Ikon that I wondered if anyone could shed some light on. I just bought the camera, brand new, about 3 weeks ago, and except for this issue I love the thing.

The issue popped up two days ago. I had been shooting away and it came time to change film rolls. I loaded a new roll and put my eye to the finder and noticed that the vertical alignment in the patch was suddenly off. I was on a long weekend away and couldn't immediately take the camera in to the dealer, so I just kept shooting, trying to focus as best I could with the distraction. I shot a couple of rolls like this. Then, yesterday, I suddenly noticed that the rangefinder was back in alignment - perfectly so, it seemed. I can't recall exactly but I think this might have happened after changing lenses. This went on for a while, but then this morning I picked the thing up and the patch was off vertically again, just like before! This final change was not related to a lens change.

So I'm a bit baffled. I certainly don't baby my gear, but I don't trash it either. The ZI goes with me on my bike, it gets jostled a bit on the crowded streets, it takes the occasional bump, but I haven't dropped it or done anything else to it that seemed worrisome at the time. I thought I had to be imagining the in and out of alignment dance, but I checked exhaustively every time it seemed to change and sure enough, focusing on a dot (for example), the two dots would never converge (with the dot in the patch passing over the top of the dot in the main finder) when the finder was out of alignment. Then, for no apparent reason, the dots would align perfectly again.

I've searched the archives and it seems there have been a number of issues with horizontal misalignment (even from the factory), but not all that much about vertical problems. I did see the thread a few weeks ago showing a DIY fix, but I wasn't quite sure if it was conclusively shown which screw adjusts the vertical alignment of the rangefinder. At any rate, the camera is brand new and I'm going with it to the dealer tomorrow. But I'm a bit worried if this is going to be a recurrent problem. In others' experience, how much does it take to throw a rangefinder off? Is it a frequent occurence? And has anyone every experienced the on-again, off-again phenomenon? If what I'm experiencing is abnormal, is there something that can be done to stabilize the finder at all (e.g. apply varnish to the adjustment screw, which I've read about)? Or could this be a sample variance issue (i.e. a problem with the rangefinder mechanism in my camera specifically) that can only be solved via exchange?

I certainly don't mean to sound panicky. I can still use the camera with the vertical alignment off, it's just that it's a bit difficult to be sure I have the focus right, it's tiring to the eye, and it's a bit irritating. I still love my Ikon, and in fact I just want to solve the problem so I can use it without worry. Any advice or information is greatly appreciated. Thanks,

Ian
 
The alignment - vertical or horizontal, will inevitably have to be corrected after some time and several bumps, but I'd say I am expecting this kind of maintenance due about once a year, depending on how much you use the camera, and on the handling. This strange "on and off" vertical misalignment sounds to me like a loose screw, or something similar, it is not normal, and I would definitely demand this to be fixed under warranty asap. I have used my Ikon for about a year before having to realign, and at this point I'd do it myself, because the repairmen are often unreliable on this point.
So, to sum up, you do not have to worry (too much) about Ikon's reliability, but in the long run, you will find (like most of the seasoned RF shooters here) that a DIY periodical RF fix makes part of the normal care of these precision instruments.

Thanks for the reply, and that's good to hear. I've been wanting to try a rangefinder for the last six or so years, and am really loving it now that I finally have. Annual DIY adjustments don't bother me at all, but this seems strange. I'll definitely have it looked at.
 
There was recently a long thread on vertical alignment, the long and short of it was no one knows how to adjust the vertical alignment, horizontal is easy.

The misalignment of my patch is vertical. Sometimes obvious, sometimes not. The angle of view through viewfinder has a very slight effect. As does distance. Have you noticed anything particular, which lens? far away / near? pointing up or down as opposed to camera being level?

Yeah, I saw the thread on vertical alignment and came away with the same impression (i.e. that there isn't quite a definitive answer as to how to adjust it, at least in that thread). Bummer...here's to hoping someone figures it out (and documents it here).

I also notice that distance has an effect on the degree of perceived vertical misalignment - close distances make it more noticeable. Viewing angle seems to have a very slight affect, but not enough to really be sure of. I thought that the patch was most aligned if I viewed something head on (i.e. no vertical tilt) but I'm not actually sure - if there's a difference it's minor. As for lenses, I've had the problem with both lenses I have (CV 35 1.2 and ZM 50 Sonnar). Does this jive with what you've seen?

Well, I took the ZI to the dealer yesterday, who is going to send it out for warranty adjustment/repair. The guy said that in addition putting the rangefinder back in alignment he'd have the repairman look at the mechanism overall to make sure it was tight and to see that it would stay in alignment as much as possible. As mfogiel said, it doesn't seem that it should fly out quite that easily.

The only bummer is that it could take up to 3 weeks...argh. I just got the ZI 3 weeks ago and having it disappear so soon is harsh. I don't have any other rangefinders, either. I suppose I should have a backup body for times like this (since I'm sure there will be more, though I hope infrequently)...it seems like most users here have more than one M-mount body. Maybe it would be a good idea to have a Bessa around...
 
Mine took three and a half weeks! I took it to the shop where I got it in Yokohama on 31st August and finally got it back on 25th September. The good news is that the horizontal and vertical alignment of the RF image at infinity is now perfect.

In comparison, just a few months back I took a Nikon SP 2005 into the Nikon Service Center in the Ginza on a Saturday for exactly the same thing and got the camera back the following Thurday.

5 days vs 25 days .... hello Zeiss! You gotta lift your game!

Out of interest. If you point the rangefinder patch at a bright led on the front of some electrical device about 2.5 metres away. Maybe slightly above or below you, does it line up perfectly vertically? I have considered sending mine away, but don't know if I'm expecting too much?

Thanks in advance.

Didn't before. Does now!
 
Yep, mine is still in the shop... I wonder how the repair program works. It didn't sound like they were sending they camera back to Zeiss itself, but rather to some kind of authorized repair shop. At any rate, I agree that it would be nice to have faster service available (and you would think it'd be easy in the country that makes the cameras).

In the mean time I picked up a Bessa R2A for cheap. I figured that it'd be smart to have a backup body anyway, and the idea of getting thrown off for 3 weeks right as I was getting a feel for rangefinders was pretty depressing. The Bessa is a nice camera, but using it does make you realize how nice the Ikon really is...
 
The paperwork I got back with the camera shows that the camera went from Kimura Camera to Nikken Techno (a camera repair service) and then to Kenko who did the actual adjustment. Seemed odd so I asked the guy at the shop what the story was, and he said that Cosina and Kenko are part of the same group. That was news to me ...
