M8+40mm Summicron-C framline problem?

Hi,

 

I am not sure if there is a problem with the lens or its just the way it supposed to be.

 

I just started to use my M8 with Leitz 40mm Summicron-C f/2. When i look through the viewfinder, I realized my frameline aren't perfectly squared (top, bottom, left and right). for example, the TOP line isn't perfectly vertical/90degree with the framline on the RIGHT. Instead, there is about a 100-120 degree angle between the Top & Right framlines.

 

Therefore, some pictures that i took are somewhat tilted.

 

What could went wrong here? please help!

 

Thanks!

 

All the best!

Do framelines look the same when you use other lenses or you move the lever of the frame selector?

 

yes, they look the same when i move the lever of the frame selector. Unfortunately i do not have a second lens to try if there is problem with my lens!

 

thanks!

The framelines have nothing to do with the lens, the mount communicates just the focal length to the camera which then slides a mask in place. It may be, although I have never heard of it, that there is a faulty mask in your camera, in fact that is the only explanation I can think off. I am very confident that this would be a free-of-charge replacement.

How do they look with no lens attached? If the framelines are tilted then, it would suggest that the masks are out of alignment and the camera needs checking. :(

 

 

Hi,

 

they look the same while no lens attached. I should probably contact leica and find out what went wrong. hopefully its part of their warranty!

 

thanks guys!

try this: try looking at a plain wall with the camera in vertical orientation. Make sure the camera is square (parallel) to the wall. Then tip the camera until you are almost looking at your feet. You should see the difference in the framelines.

 

You can also tape a rectangular piece of paper to the wall to check the framelines.

 

Also, it is normal for the framelines and patch to move as you turn the focus ring.

I agree with the others:

1) There's no way a lens can cause the frame lines not to be square.

2) Because of the way they're made, it's virtually impossible for the framelines not to be square.

 

Simply try taking pictures. My guess is that you're not used to using a rangefinder. You need to get used to how the frames frame the image; then all the misalignment you think you're seeing will disappear.

 

Only problem I see is that none of the M8 frames are exact for the 40/2, so your initial learning curve may be a bit steeper at the outset. :(

I think it is just literally perspective. Like when you shoot the focus chart at 45 degrees it makes it look like the framelines are not rectangular.

 

BTW I have an r-d1 with a patch cutout that is irregular.

 

Let us know how it turns out E.

The M8 35mm frame lines are more accurate with the 40/2 than with 35mm lenses as long to medium distance when the flange of the lens is filed for this purpose. You know it of course Howard but maybe not the OP. How to modify a 40mm Summicron-C (with photos) - Photo.net Leica and Rangefinders Forum

i tried placing a rectangular paper ro the wall and still, the framelines are still un-perfectly squared............the right framline is still tilted to the Right..... gradually.

hi, i did modify my lens to make it fit into the lever and a 50mm framline is showed.

 

however, i don't think lens has anything to do with the irregular frameline........cuz when i took off the lens...result is unchanged

 

thanks!

Did you file the flange to bring up the 35mm frame? If so, there is definitely something wrong with your camera i'm afraid.

 

yes, i file the flange but, i brought it up the 50mm frame.

 

well, its still the same when the camera is without the lens

Emilu--

Have you taken pictures with the combination?

 

Do they look like what you'd expect?

 

 

Can you take a picture thru the finder and post it here so we could see what you're seeing?

 

 

BTW--

The 40/2 C was designed to bring up the 50mm frame in the M camera, so if you're seeing the 50mm frame, you're either filing the wrong flange or you haven't filed it enough.

 

But without the lens, the camera should show the 35mm frame; so if you're seeing the 35mm frame with the lens, you've filed enough.

 

:confused:

 

I think we need more information before we can actually help. :(

I'm really curious too. I thought he said only the right side 50mm frameline is bowed, and when he moves the preview lever in either direction, he still sees the 50mm frameline.

I'm intrigued too. I had thought originally that the whole frameline mask might be tilted and out of alignment, but the later information sounds more like some confusion related to perspective.

 

Emillu, please would you be so kind as to post a couple of example pictures, or diagrams (As requested earlier by Howard.) so that we may be better able to help you? :)
