M8+40mm Summicron-C framline problem?

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.

 

 

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

 

 

Hi,

Thanks guys for helping! and sorry for not explain myself clearly.......i meant to say that i am seeing the "35mm frame" with the lens clipped on. I can still see the problem (irregular frameline) even when i move the frame selector up to show the 50mm framline.

 

Yes, I have taken pictures with this M8+40/2 combination.

I have attached a simple drawing of what i see in the 35mm framline. The reason why i would care about this so much is because it affects my perceptions on a image and my shots would tended to tilt to the right.

 

thanks again!

Therefore, some pictures that i took are somewhat tilted.

Sorry, I missed this when I asked whether the pictures looked like what you expected. My error.

 

I don't know how far off "somewhat tilted" is.

 

I often find that my pictures with any camera are tilted a bit, maybe a degree or two. Don't know why, maybe it's my sloppiness, maybe my inattention, maybe my astigmatism.

 

But because of perspective, you don't normally use the framelines to line up verticals or horizontals; you do that just by looking thru the camera at the subject.

 

Is the M8 your first rangefinder camera? What camera did you use before?

 

Could you post one or two of the pictures that show the problem? It's possible that you're over-reacting to a surprise that may be easy to explain.

 

 

You've got a number of us interested, so feed us more information!

Emilu, somehow I got completely out of synch. I didn't see your post #21 until after posting my #22. Just not paying attention, I'm afraid.

 

Believe it or not, your diagram looks fine to me. With Leica's framelines, where your eye is relative to the frame can make a slight difference, particularly keeping in mind that the framelines move diagonally as you focus.

 

But there's a real problem here: Because of the way the framelines are made (holes cut out of sheets of metal), it's impossible for the top and bottom lines to be horizontal and the side lines not to be vertical.

 

So the only thing I can think might be causing the difficulty is an optical problem. It could be from the angle at which you're looking at the frames, or the fact that you're looking through another part of your glasses (since I wear glasses, I figure everyone does ); or it could mean that there is a problem in the viewfinding system of the camera. Could be a loose diopter not properly installed, or (very unlikely but possible) it could be a problem with the viewfinder prism.

 

 

Here I'll go out on a limb and say you need to quit looking at the finder frames. They're just there to help you visualize the subject that the camera is looking at. It's like looking through a window: You don't pay attention to the window frame, but to what's on the other side of the window (unless you're planning to tell your partner he needs to repaint the frame ). Pay attention to the subject, just be aware that the framelines are only there to guide you.

 

It's like driving a car in the rain. You pay attention to the traffic; you're aware of the windshield wipers, but they're just in the background of your consciousness.

 

Just my opinion, based on what you've said. I may be completely off track and I'm not saying you're doing anything wrong. I hope something I've said here helps.

yea, first i thought that i didn't put my eye ball at the centre of the viewfinder. in fact that's not the case. yes, i should not pay attention to the frame line, instead i should be looking at what's inside the frame!

 

If you say there is no way for the frame lines not to be horizontal and vertically displayed, there is gonna be a problem!
