Thanks Jeffery. I feel confident that an external 35 would be very close. I 
don't think that the lines are desperately accurate,
anyway, are they? Danged if I can compose that accurately. I always have to 
crop off about 5% due to the proportions of an A4 print,
anyway. That and adjust for an apparent one degree tilt that using my left, 
master eye induces! I guess a quick test with the 28
lines brought up in the M8 finder would tell you how close it is to that one.

It does highlight one issue for me with the M8, though. I do know that this 
isn't new, of course. Just to achieve my favourite
travel FoV, the 28, I'd have to fund the 21. Or the new T-E wide. And THAT 
one costs about AUD 5,500 here (without the finder, I
think). Let's see, right now we have our best exchange rate for a long time. 
1x M8 plus the T-E wide (no finder, I think) just about
exactly USD 10,000. Yikes. Still I guess the 28 would act as a nice 35ish 
standard, and the 50 asph ought make a good portrait lens.
I'm going to stop thinking about this right now.

Cheers
Hoppy

I did this in Excel a week or so ago.

35mm    M8
15      20
21      28
25      33
28      37
35      47
40      53
43      57
50      67
75      100
80      106
85      113
90      120

So, the 25 would be an odd-ball for which there are no external finders. In
a pinch, I'd probably use a 35 finder a realize that it was a bit wider in
reality.

Jeffery, I've read and marvelled over those quoted figures from Zeiss as
well. Not likely to see this sort of resolution in any normal situation, let
alone print, though! Still I've read nothing but positive reviews on this
lens. Don't know that I would be keen to take a file to it for frame-line
reasons, however. An external finder seems a little more civilised solution.
What should it be on the M8, very close to the FoV of a 35 on an M6? 
Hasn't Tom A got this lens and an M8? I'm sure that he can fill us in.

Cheers
Hoppy

As I recall, the Zeiss Biogon T* 2.8/25mm broke some sort of record for
sharpness (400 lines per mm?). That seems incredible, considering that there
are only 1000 micrometers in a millimeter. Does that mean it can resolve an
object the size of a red blood cell?

It has been, so far, my standard lens.
Amazing lens. Great value (in the Leica scheme of things)
