Having just bought a Summicron-c 40 for my M2, I was wondering if there was a way to add '40' framelines to the viewfinder? Would it be possible to place a piece of plastic with the lines in front of the window? Thanks.

No the mask must be put inside, just use the 50, or the 35 frameline, it's good enough

This is my favorite lens and focal length. I know it will drive you bonkers in the beginning, but it will pass as you get used to using the 50 framelines as a tight frame for the 40mm. You can flip the frameline lever between 50 and 35 to see the inbetween you're missing. I usually try to put all the "must be in picture" subject matter inside the 50 framelines, and so far it seems to work for me. This lens is usually stuck on my M4-2.
If you must, there is a 40mm external VF available from Cosina Voigtlander, or just get a Bessa R3A/M. I've tried it on the R3A, and it is a match made in heaven if you like this lens. And you will, you will...

I have this combo on its way to me. My first RF camera so it'll all be new and interesting. Can you set the frame preview lever to 35 and have it stick? I don't want to modify the lens

You can kind of hold with a piece of card or something, but it's awkward. It's also better in my view to shoot it as a 50 and expect a bit more, rather than cut things out using it like a 35. It's nice to hear of somebody who doesn't want to modify the lens anyway, eventually most of them probably will be.

I think you're right. I used my M-Rokkor 40/2 with my M2 for the first time yesterday, and I came to the same conclusion. Very nice combo, BTW.

Hm, I'll see. I wanted to be closer to the correct framing, but maybe you're right. Might be safer to have too much in the frame than too little.It's also better in my view to shoot it as a 50 and expect a bit more, rather than cut things out using it like a 35.
I just don't like doing permanent modifications to things. If making the lens bring up the 35 framelines was just moving a little screw or something I'd do it. Once I read it was filing down part of the mount, forget it.It's nice to hear of somebody who doesn't want to modify the lens anyway, eventually most of them probably will be.

Rangefinder cropping will never be perfectly accurate so stop worrying about it!

This is a photo taken with the 50 Elmar-M:
These are 50mm M2 and M6 framelines with the same scene:
40mm is 20% wider than that. Just to quantify the difference. I would rather use 40mm framelines with my 50mm lens, than vice versa

Thanks, Roland -- I've been looking at that sentence and the pictures for awhile. Did you write what you meant or did you mean "I would rather use 50mm framelines w. my 40 lens than vice versa". That's what the VF pictures seem to suggest.

Thanks for the replies everyone. I've been using the 50mm framelines and it seems to work well - at least I'll never cut off someone's head/feet! The lens is absolutely beautiful to use; so compact and much better built than the Summicron v4 that I used to own.

Think of 40mm as a 50mm lens with freedom for composition.

the framelines show less than what seems to be on the picture, so it's more "accurate" to use wider framelines than the focal length suggests. I think he got it right.

Thanks, SSS, I felt sluggish when I wrote that; now I see I was asleep. Of course, you're both right.
