So far, the 90mm framelines seem to be perfect for the Nikkor 10.5cm F2.5. I've been using the inner portions of the framelines, and get very good agreement with what shows up in the stored image. I've been using the inner portion of the frame. This agrees with what I found on the M3: the 90mm framelines show about 100% of what is on the Negative.

They are too "loose" for the 90mm Summicron, and you simply envision about a 10% margin.
 
The 90 Summicron has significantly shorter min. focus than the LTM 105/2.5 Nikkor.

Focal length changes quite a bit for tele lenses when you get close. Which is why the M3 90mm framelines work well for the 105/2, a 1m 90mm summicron, and a .7m 75 summilux :), depending how far away your reference point is.

Ah Ha! I see it. The M8 framelines are optimized for closest focus, on the 90 Summicron that is 103.28mm

So- at working distance the Nikkor is "Just a Silly Millimeter Longer"...
 
I can report the same, using M8 + Canon 100/2 is no problem when it comes to framing at "normal" working distances
 
I don't want to hijack the thread, but I was wondering if anyone had any ideas that would help me focus a 90 lens on an M3. That little rectangle sure looks tiny after using the SLR cameras! Magnifier perhaps? The idea that the 90 frame lines on the M are actually LARGER than the film negative is amazing.

Try with both eyes open. Not so tiny really, to me they feel like 50mm framelines in an M6.

M3 I usually do without magnifier, which does help on .72 finders.
 
As you may know, the M8.2 frame lines (also available with M8 upgrade) are better optimized for longer distances.

I know the optimization for the 8.2 is for longer working distance. However, I like the way the M8 is working out. I plan on keeping the LTM adapter and Hot mirror filter on the 10.5cm F2.5, one of my favorite lenses.

I bought a 1.25x magnifier for the M8 for use with the longer lenses. Works great.

Focus is spot-on.
 
This is one reason why I'm jonesing for a Canon 100mm at the moment--it should work perfectly for those framelines. At the moment my canon 85/1.9 is a little wide!
 
spare 50/75 adapter?

If you have one of these lying around, might be interesting to see how your 85 works in the 75 lines?

I've got the 50 LTM adapter on my M8 now- and will try the Nikkor 8.5cm F2 with it. At 6ft, I'm betting the inner border of the 75mm framelines are good. Look at Roland's chart for the 75 lens at 0.7m- it's at 84mm EFL.
 
Just to follow-up: I used the Canon 85/2 with the 75mm framelines. At 5ft, the framing is very good. I will use my 85mm lenses with the 50/75 adapter from now on. At 4ft, I used the inner framelines and it looked good, but would advise anyone to check on their camera.

Got everything in the 75mm framelines with this shot,Serenar 85/2 on the M8:

So, the M8 framelines worked out for me. It's those people that insist on using the wrong focal length with them that have the problems...
