Hi Brian
That's pretty much it. The film M's for half a century were accurate at 1m and this was fine for most folks.
When they designed the M8, many more lenses were focusing closer than 1m, and more photographers were shooting at minimum distances, so in order to take the conservative position, and not allow for framelines cutting off edges, they went tighter to 0.7m.
M8 owners couldn't take this, since all distances except beyond .7m were "loose" so they went to 2m with the 8.2. This was too severe, and causes "data loss"
The M9 is back at 1m, and all seems well again.
I am fine with the framelines of the original, agree that 40 fits 35 better than a 1m close focus 35 though. With 50, you'll want to use the insides of the lines at distances.
75 corners work fine for me, but my 75 close focuses to .7m, so I wouldn't want them optimized for 2m and beyond.
90 was fine, but is small in the .68 VF, there are no 135 lines.
Never tried framing with the 24 lines paired with the 35, but do use a 21 with the whole area of the VF which is still tight, but I can get level shots.
With a 15, I need an external VF (21).
I read up on what the issue was. The framelines for the original M8 were optimized for closest focus, meaning they cover the lens at a slightly longer actual focal length. Works for me, a lot of my shots are close-up and wide-open. The marked focal length for a lens is for infinity focus. The margin for the framelines is different, and on some focal lengths the actual image is stated to be smaller than that shown by the framelines when used at infinity. However- for the 50mm framelines, the view at infinity still has plenty of margin in my experience. Roger's solution of using the outer portion of the framelines serves to match things up. The M8.2 shifted the framelines to match FOV mid-distance at ~7ft. Better for many applications, but not all.
I'll try the 9cm F2 Summicron on it. If it's off, I'll just use the Nikkor 8.5cm F2 with it for my longest focal length. Ya think that's what they had in mind...
