The Leica IIIs are hard to focus , and slow.

<p>

Try screw lenses with the Bessars. Much faster and more accurate.

Roger, I held the camera in portrait format, so I believe the shutter

slit would be perpendicular to the image. Therefore, the stripes are

perpendicular to the shutter slit and parallel to the image.

<p>

As to whether the stripes are parallel to the film , i dunno. As

IMAGE FORMAT may differ from FILM FORMAT.

See the stripes?

Hi guys, looking back at my previous posts about Streaks on my M3, I have discovered that even my M4P and new M6 classic have some perculiar performance in bright sunlit sea scenes.

<p>

When I shoot with the later 2 bodies at 1/1000 at about f8, there seems to be BLACK STRIPES running parallel to the film ACROSS the image. I dun get this with SLRs or Bessars.

<p>

These black stripes occur mostly in scenes with the clouds as background, and in very sunny days.

<p>

I believe the M curtains, with their horizontal shutter slit moving across the film during exposure may be UNEVEN in speed and width, even in new Ms, causing uneven exposures across the frame in high shutter speeds, HENCE THE BLACK STRIPES ACROSS the pic. Slower than 1/1000 speeds are FINE, in my experience.

<p>

I would like to seek your experience with these scenes.

<p>

I will post some sample pics if there are enough collective evidence to my point.

<p>

Thanks.

Glenn, excellent photo .

<p>

What filter did u use? UV?

<p>

The Elmar was good, but u were better here. ;)

<p>

Keep posting.

Sait, got it.

<p>

Thx for finally solving the mystery.

<p>

Really appreciate it.;)

<p>

At least I know now why I had to part with it.

Jim, YES the streaks are there in the color pic. That was the last

time I used the Bumpy M3. I used it to test the DR 50 before letting

it go. That M3 has a very very soft shutter release, but sigh, too

bad I guess.

<p>

Anyway, the elmar pic was shot using Bessar R. NO STREAKS!.

Randy...yea..I know;)

<p>

sucks doesn't it??;)

This is the Elmar 3,5 photo.

Hi guys, I recently traded in a BUMPY (pls read my thread and Sait's thread on Streaks on M3) M3 for a DR and elmar 3.5 LTM. This is the first time Im using both lenses.

<p>

The DR is brilliant. Positively glowing and sharp. Although heavy, it is a joy to see the results.

<p>

BUT the ELMAR 3,5 is undoubtedly the closest to a Leica Glow I'd ever imagined of getting.

<p>

It , at mid apertures, produces prints better looking than the asph 35 cron that I have.

<p>

No light fall off, no flare . Lightest changeable lens I've used.

<p>

I know many have used this lens, and I think everyone should have one.

<p>

It is not staggeringly sharp like the asph cron 35. It is not even contrasty in comparison. But the GLOW and Roundness it gives cannot be understated. The later lenses do not have this in my experience.

<p>

In low light, the asph cron is the one to go for. But in normal use, I think this is as good as it can get.

<p>

Shot with Bessar R.

Sait, I seriously think you have gotten the REASON for the streak

problem. How did you learn of this, and what did u do to correct it?

<p>

It seems very logical, the bump/pimple theory.

<p>

Randy, credit goes to u too! Brilliant.

Question is, if there are BUMPS, how do I pry open the two shutter

and then smoothen the edges???

<p>

damn.;)

Thx Sait.

<p>

Jack, the streaks run PARALLEL to the length of film in all problem

pics. So, the BUMP ON SHUTTER EDGE theory HOLDS.

<p>

Just to clarify that I understood what Michael, Randy and Sait said

earlier in my thread

<p>

I believe that if there is a BUMP on the upper shutter edge of one of

the curtain cloth, then as the shutter slit travels across the film,

the track of streaks will be formed in line with where the BUMP spot

is, BECOS LIGHT WILL BE BLOCKED. aM i RIGHT?

<p>

SO, according to my pics, I think there are a FEW BUMPS on the upper

edge.

<p>

I hope i know what I just said!;))

<p>

DR 50. FUji Color 400. Good lens, but its heavy. The later 50 crons

are nicer to handle, abeilt harsh in contrast.

Sait, thx for the info. But it still doesn't (I think) explain the

pattern of streaks, which is running the LENGTH of the negative and

not perpendicular to it, as would happen if it is a shutter slit

problem.

<p>

Anyway, noone in my area knows why the problem arise, and of cos how

to solve it.

<p>

Camera is TRADED. Life goes on. My bessa R has no such shutter

problems. But hey, its also not 50 years old ;)

<p>

Thanks guys for all the input. Greatly appreaciate it. ;)

Michael, say its the processing. But its on the negs. So the

developing is at fault too?

Horizontal shot uncropped. Same scene, about f8 1/1000. COntrast

added to show circled streaks.

Michael, excellent description. But that doesn't explain the pattern

of the streaks in my case, does it?

Steve, thats very noble of u. Im very grateful.

<p>

But Steve, I have recently traded back that M3 for a dual range and

3.5 elmar. Im very happy about the switch.

<p>

I just thought some folks here might have experience this problem.

But as I can see, there could be many reasons behind this. Im pretty

sure Lab is not the problem because the streaks were there when I

developed the film myself, abeilt less often.

<p>

Thanks againg for the lovely gesture, Steve.

uneven slit width :

<p>

Randy, what is that?

Randy...I would hazard a guess that most of the problems occured

during F8 and 1/500-1/1000 as would be needed in brightly lit sea

scenes.

Michael...this is a vert pic, uncropped. The streaks occurs on the

upper horizontal section OR aka the right vert section of the

viewfinder. That is, the lower horizontal section OR aka the left

vertical section of the FILM .

Preston. Color and B&W of various brands. The self developed b&w

however, seems less affected.
