Shooting 75mm on an M3

[nome_alice]

I have a Bessa R2A and just picked up a 75mm Color-Heliar, please forgive me, but...

I have an M3 on it's way (obsessively watching tracking right now) mainly for shooting 50mm but on inspecting the 75 and 90 framelines on the Bessa there's such a minute difference i got the thought that I might be able to use the 90 framelines on the M3 for use with the 75mm Color-Heliar without too much of a problem, remembering i can probably let things go right to the 90 framelines and be safe. (i just need to get a 90mm adapter)

do you think this would work ok? as i'm shooting a lens slightly wider than the framelines i don't think i'll be in danger of cutting heads off, a fair assumption?

anyone tried this?

cheers.

Guesstimation isn't an exact science. You can either do it or not.

There's a 75mm finder from Voigtlander that's widely available.

IMHO it should be no problem and you can easily compose with the 90 frameline. And as you said - you can compose right to the framelines and even a little out without fear of cutting somebody's head off.

the vf on the r2a is x0.7 , while the m3 is x0.91. so while the difference between the 75 and 90 framelines might not appear much on the x0.7, it would be magnified a little on the x0.91.

framelines on the m3 are 50-90-135. so you can either use the a "smaller 50" or a "larger 90" to approx the 75. i would prefer the latter with the m3, esp in minimizing the risk of "cutting off heads". else another possible solution should be the r3a, with a x1.0 vf and 75 famelines.

I prefer a separate finder -- I use a Tewe.

I've been using an M3 since I got a 75mm. Not a problem.

thanks for the info guys, b&w yeah i had a suspicion i'd have to factor in the differences in magnification. hopefully it's not too drastic.

i just have to have a play around with it.

I will often simply toggle between the 50mm & 90mm frames & guesstimate that way. It also helps that I routinely use an M6 TTL & M7 & can pre-visualize the 75mm frames inside the 50mm. If you're considering using the CV 75mm accessory finder, I have 1 caveat: it is apparently designed to be used w/the smaller "Barnack"-style thread mount Leica bodies, so the parallax correction marks are not accurate for use on an M-mount body (due to the difference in height).

One version of the VIOOF finder by Leica has 75mm framelines. They are relatively common and not expensive but they are bulky being a multi finder.
