Dominique,

What I want to point is that the Tri-Elmar is better (in my opinion) than what
CI say about it.
And the same for the APO 90/2 ASPH.
There is more difference between the former 90/2 and the APO than what they
said IMO.
But maybe they tested two below average lenses in both those tests.

Dominique,

I'm reading CI since more than 20 years now, and I never missed one issue.
I know perfectly well they are not sold to any company.
But they are sometimes biased by there own beliefs.
And that's part of their strengths.
They have strong beliefs and that's great.
But they are certainly not not omniscient.

By the way, I cannot read MTF graphs like you do.
All I can do is take pictures and look at it with a loupe or project them on a
screen.
And there I can see that the Tri-Elmar is really a great lens.
It's really an achievement when you realize all the constraints they had in
order to make it happen.
It was much more difficult to design it than a Reflex zoom.
