CV 40mm Nokton Frameline

If anyone is using the CV 40mm f/1.4 Nokton on an M8 can you please tell me which frameline comes up when this lens is mounted? I like this lens on my R-D1, but don't have my M8 yet and I'm curious about performance with the M8.

It brings up the 50/75mm frame set on the M8 (or at least mine does ). For scenes that are 4 to 5 feet away the 35mm frame is a much better approximation. However the area covered by the 35mm frame is very slightly more than that of the 40mm lens so there is no safety margin.

 

Although the 40mm brings up the 50mm frame it is possible to have a small amount of the 40mm lens mount removed so that it will bring up the 35mm frame. You can verify this is so by rotating the lens slightly as if you were dismounting it, the 35mm frame will appear.

Yes, Tom Abrahamson (of rapidwinder fame), did this for me a few weeks back. My 40mm now brings up the 35mm frame on the M8 and it works like a dream.

 

Cheers. Terry.

I have both the 40 'cron and the 40 CV, they both bring up the 50. I personally like the 50 frames over the 35, so that i always have a safety net if I forget what lens is up. It helps me focus on the action a little better.

I filed the mount on my CV 40/1.4 so it would bring up the 35mm lines. Using the 50mm framelines was just too much of a crop for me. OTOH, I have to remind myself to stay inside the 35mm lines... In any case the 35mm lines are closer to the lens than the 50mm lines. As a bonus, I really like the uncluttered view of the 35mm framelines.

Cheers, David.

i did the same. i spent a few days shooting with both the 35 and 50 framelines and decided i liked framing inside the lines instead of out. otherwise, i think i'd be too tempted to crop all my pictures to fit the 50mm field.

 

it's an easy modification if you're careful. just remember it's not easily reversible.

For the record, a 35mm lens has a 64-degree angle of view, the 40 is 57 degrees and the 50 is 45 degrees, so the difference between the 35 and the 40 is 7 degrees, and between the 40 and the 50 it is 12 degrees. Having said that, I prefer on both my M7 and RD-1 to use the 40 with the 50 framelines because I'd rather frame looser than tighter.

Thanks all for the replies. I'll go with the default 50 frameline first and mod the lens mount if that doesn't feel comfortable.

Carl, remember that you can also use the frame preview lever to see the 35mm frameset if you wish. (Quicker than loosening the lens as Bob suggested, but maybe no more practical.)

The other option is to use an external 50 mm finder such as the Voigtlander. The 40 on the M8 shows about a 53 mm EFOV and the frame lines on the external CV 50 finder (like most) run a bit tight (probably close to 53 mm at most distances). I've just requested that finder for my 40 Nokton test but my guess is that its FOV will be well matched the CV 50 external finder. That finder also has a 1:1 mag. which is nice for those of us who like to view at life size.

Thanks Sean. I like the 1:1 mag with my R-D1 and R3M so the CV 50 external finder on the M8 might give me a familiar view when using the 40mm Nokton, as well as a close FOV match.
