Youxin works on Leica's because he enjoys it, and really likes them. Same as Kim Coxon working on J-3's and J-9's.

Lens is back. As agreed, Brian did not accept the parcel: so the postal services had to return it to me at no charge. YY should have posted the M2 nine days back, so it should reach me any day now.
I now have a fundamental question about optical devices. Travel is said to help humans by broadening the mind and so on. Is it good for lenses too?

That lens has been around a lot. Russia, India, Britain, the US, and back again.
It will refuse to do lens chart tests. It's seen the world.

YY replaced the curtain with a "good used" one, apparently on the day he got the camera. The R/F is now accurate at 1 metre.

Youxin has a surprisingly fast turn around time. With a correctly focusing rangefinder is there still a need for an eyepiece magnifier?

A magnifier cannot but be a help -- but I don't think I need it badly enough.
Brian: "Youxin works on Leica's because he enjoys it, and really likes them. Same as Kim Coxon working on J-3's and J-9's." There's a difference. Kim fixed my J-3 for me and did not accept even the return postage that had been agreed upon. Youxin took nothing either, and paid the return postage -- but then the camera had been bought from him and had had a bad curtain from the start.

No one is perfect. I've sold cameras that had a defect, and have taken them back. Same with lenses- fixed lenses, missed something, took it back and fixed it or refunded it. I've had cameras repaired professionally, paid a lot more than Youxin charges. Came back, worked for a few rolls, seized up. If you could not detect the problem in the curtain visually, and thought the lens was the problem, I would have probably missed it as well.

All is well now, Brian, and I have no complaints. But there's no doubt that much trouble and some expense could have been avoided.

Payasam,
sorry to learn your troubles are not yet all past with the camera. I feel both you and the M2 deserve better.
So, shutter curtains will have to defy gravity when you shoot, am I correct?
Might be another issue with shutter spring tension then.
I just read the whole thread and found your earlier post proposing to shoot a blank wall to sort out the earlier problem.
You might possibly identify the problem by shooting half the roll with the shutter release up using various shutter speeds and documenting, while shooting the other half of the roll with the release button at down side, again various shutter speeds and documenting.
If spring tension is in any way involved, this should expose it, I reckon.
You might be able to negotiate a full CLA at reduced price with Youxin Ye if it needs to be shipped out again, so any lurking future problems can be addressed right away?

Thank you, Johan. It cannot be anything to do with spring tension, because in a horizontally travelling focal plane shutter that would have affected the entire width of the negative. The light leak runs along the long side of the negative close to one edge. The only time I have faced such a problem was when the lower light shield of a IIIc was not re-installed correctly. If the camera goes anywhere, it goes to my trusted man in Calcutta (now Kolkata). I know that until then I should not change lenses except in low light -- or else skip the frame in the gate because it may well be a fogged waste.

Payasam,
Very sorry to hear of your distress. I'm not an expert, certainly not with Ms, but this may not be entirely unexpected behavior. I'll check my Leica Manual tonight or tomorrow. I know I've read in a couple of places that lenses should not be changed in bright light. If I have to do it with my IIIf, Fed, or Bessa, I always hunch over and turn my back to the sun. That way I can at least create a little shade in which to change the lens. As I said, I'm not an expert. I'm sure somebody who knows more than I do will be along shortly.

Of course you are right, Bill; but one does not need to be any kind of expert to have a modicum of common sense. Besides, all of us learn from what we see older people doing.
From 1975 to 2005 I used two Canon SLR bodies with several lenses. From 1985 to 2002 I had a Leica M3 and a Canon VT Deluxe, also with several lenses. I was active as a photographer, and I changed lenses when I needed to do that, often in daylight in open places. Not once in all those years did light leak past a shutter on to the film. But here is what I am told:
"If the light leak only happens after you change a lens, it is normal. As new Leica camera instruction suggests to keep camera under shade to change lens. Also Leica manual advised change lens in day time may cause light leak."
Does the fellow think I hold the open mouths of cameras up to direct sunlight when I change lenses?

To me it seems that light is creeping around the lower edge of the shutter curtain. I assume you are shooting negative film? The light seems to come from the front, otherwise it would have the colour of the film base.
Also the problem you posted yesterday seems different from the one on your first post in this thread. It was probably worth having the curtain replaced, the hole is gone either way.
Incidentally I like the portrait shot you lost, it would have been a good one.
At this point it's probably worth wasting a cheap roll of film trying to reproduce the problem. Can you try and shoot a number of pictures in strong daylight, changing lenses regularly, so that you can check:
- whether it happens only before cocking the shutter, after cocking it, or in both cases;
- whether the light needs to come from a particular direction (you could try changing lenses with the lower edge of the curtain in direct sunlight, and shaded off by the bayonet mount).

Thank you, Philipp. I have done pretty much what you advise, except that I used a flashlight. Must wait for results until the roll is finished. The earlier problem and the present one are entirely different from each other. The curtain had to be changed, of course, but my undoubtedly selfish view is that it was perhaps not necessary to introduce a light leak.

I hope your test roll comes out OK. I checked the '62 Leica Manual, and it does say not to change lenses in bright light because film fogging can result under certain circimstances. I'm sure you already know that, but maybe you've just chanced upon one of those odd circumstances. Good luck.

Given that film is sensitive to light, it follows that it must be protected from unwanted light from all possible sources. This is what all camera manuals emphasise. Nearly all shutters are light tight in normal use, but their light tightness is not absolute and cannot guard against stupidity of a high order. Experience may not eliminate stupidity completely, but in general it does tend to lessen it.
Of course the leak could have been a one-off thing: but its severity makes me doubt that.

Do you use slide film? If so, it could theoretically also be the back cover that is at fault. Is the back cover tight on the camera?
payasam
a.k.a. Mukul Dube
Negative film, Philipp. The back cover is fine. As the camera has no case, a leak from the rear would have manifested itself many times; but there were no problems in the year and a half before this one showed up after a curtain change.
The "one off" argument is supported by two facts. First, the camera is seldom used outdoors in bright light. Second, I do not nowadays change lenses as often as I did earlier. However, as I said before, I am inclined to consider this a fault of re-assembly.
