Just came back with my M2 from the check-up. The guy said the problem was casued by the fact that the winding went a bit too far, partially due to too fast and too harsh winding, and partially due to the fact that some winding gear there inside (I don't knwo what it is called) that has worn off a bit. Changing that gear (if a replacement can be found at all) would likely cost about 200 euros!!! But for now, if I do not wind the frames too fast or too harsh, all the shots should turn out fine. Let's see.

Thanks for all the reponses.

 

Just developed three rolls of TriX.

Have not gone throught them thoroughly as they are still drying.

 

One roll with Voigtlander Ultron 35/1.7 only on a Leica IIIf body.

 

Going through the wet negatives briefly, I cannot notice blurred images on this roll with Leica IIIf. This means there is possibly nothing wrong with the lens.

 

Two rolls taken on newspaper with a tripod.

M2 with Voigtlander Ultron 35/1.7, Elmar 50/3.5, jupiter 35/2.8

Shots were taken with different shutter speed and aperture values. Some of them were taken handheld.

 

Some of the images taken with Ultron show blur on the usual left side. The other lenses do not seem to show any. The blur tend to come much more often when the shutter speed is 125 or 250. This is also true among all the other blurred images I have found.

 

I will probably have a closer look at the negatives and scan them to enlarge them on the computer screen. But then now I wonder hwo that could be possible that the combination of M2 and the Ultron gives raise of those blurred images, and especially when shutter speed is 125 or above.

The case of Bj�rn is something that I kind of hope to be true. If the warraty is still valid at all, I find it rather troublesome to send the lens back to London. Or then I would need to spend some substantial amount to get a new lens.

 

Going through the pile of contact sheet again, it looks like the blur comes around almost in every roll of 60+ rolls. But then sometimes there are only 3-4 shoots affected in one roll. This makes me kind of wonder, if there is a loose element in the lens, how does it work so that sometimes there are more and sometimes there is less shoot affected? And would this defect get worse?

Thanks again for the replies and the comments. One question is the warranty usually one year? I bought the lens from Jessops in London, would it be possible anyhow I could get it fixed without sending it back to London (if there is really something wrong with it)?

 

Should there be any sound at all if you shake the lens?

 

Just did two rolls of test photos. Should develop them tomorrow. The blur in the photos definitely have been caused by either the lens or the camera. Goign through the contact sheet, they show up in a rate of about 1/4 to 1/3 among 60 rolls of films. And they also show up as they are when scanned from negatives. Many of them are visible even on negatives without magnifiying.

Thanks for the comments.

 

If it is the lens or then the lens mount, how come 2/3 of photos in a roll are usually perfectly sharp all through? One possible explanantion is that there is some lose element inside the lens that sometimes it moves and sometimes it does not. But then again, if that particular element is proned to be shaken, it would be kind of hard to get any totally sharp shot then? I will carry some thorough test with newspaper as suggested. Let's see what happens.

 

As mentioned, more photos and a little bit bigger ones can be seen in the webpage listed above.

I have been taking a lot of photos with my M2. Recently I have

noticed something rather disturbing in the photos taken with the

camera. A substantial portion of photos have the left half blurred.

The difference can be seen in the some of the photos in this page.

First I thought it might be the way I often shift the camera when I

rewind the shutter after each shot. Last month when I was travelling

I paid special attention to that habit and held the camera pretty

steadily for every shot. And today among the freshly developed

negatives I can see the same kind of blurred halves among the photos.

 

However, I do not believe the blur is a result of my hand shaking.

Otherwise, there would not be such a uniform pattern of blur

appearing ONLY on the left half of many photos. Some of the blur is

even more obvious and severe than others. The blur appears even when

the photos were taken with a shutter speed of 125 or 250 with

aperture at 8 or 11. These are the usual settings I use with the M2.

 

Apparently the shutter curtain travels from the righthand side to the

left. This means any shaking after the shutter is released that could

a blur should affect the right half of photos more readily than the

left. However, the blurred half is on the left of the photos, which

is apparently the right half of the camera body, the side right under

the rewind lever, AND the side that the shutter curtain covers first.

 

One thing I have also noticed is that I do not remember seeing such

blur in photos before I started using this Voigtl䮤er 35mm/1.7 lens.

Before that I only used the Russian made Jupiter 35mm. I cannot see

any defect in the glass of the lens. But then again, how could there

be something to do with the lens? Especially when not all the photos

have been blurred, and the area blurred can be betwen 1/2 and 1/4 of

a photo.

 

Anybody have any experience or advice on this particular issue?

Could it be something to do with the shutter release? Or that the

shutter is over senstive with certain speed, such as 60/125/250

(which I use most of the time), that causes tiny vibrations inside

and cause the blur?
