Leica R vs M 90 Summicron?

How different are the looks of the two 90 Summicrons? (pre ASPH)
They go for around roughly the same price

Hello,

If you mean those 2 Summicron 90mm:
http://www.summilux.net/r_system/Summicron90.htm
http://www.summilux.net/m_system/obj...cron90-II.html

I have used both in R and M, never seen differences in photos.
...with same same optical cells by Doctor Mandler himself.
Only R mount focus closer to 70cm ( M focus to 1meter).

Portrait images very nice from these lenses.
Some softness wide open and "better" close down a bit.

In practical photos there's not much between them, however there are subtle differences between the Summicron M v2, v3 and Summicron R.
The first is the best for wide open photography - is the sharpest at F2.0 and with the smoothest bokeh, v3 is better at smaller apertures and in the field, so if you are after a landscape lens, this would be the version to get. The R version is on paper the least sharp of the three, yet it delivers great images all the same, and has the advantage of through the lens focusing for closer images with off centre subject. Overall, this is one of the great Leica classics.

These are all from the R version:

It is the heavy version with a built-in lens hood. It is softer when used wide open, but I love it overall.

No, version one is SOOZI-M(11127) or SEOOM/11123 produced between 1953 and 59. It was looking like Summarex.

Yeah, I think I'll go with one of the different big bertha versions if I decide to pick one up- it'll have to go on my Sony A7 for now

After seeing this shot, I want one! The ASPH is smaller, but the spherical versions make lovely images in their own way!

The hood that looks like a collapsible drinking cup? I always liked the looks of that one--always wanted one.

Yes Raid, there's a good description on this lens in the Puts' Leica Compendium.

Erwin Puts has compared the performance of the M vs. R versions of the 90mm Summicron. On pages 175-76 of his Leica Lens Compendium, he says ". . . at full aperture [it is] not as good as the M-version from 1963. At full aperture contrast is low to medium, with coarser detail recorded with fuzzy edges. . . Flare is somewhat less well suppressed. Stopped down to 1:2.8, image quality improves markedly and from aperture 1:4 there isa gradual improvement until 1:5.6, where an excellent quality is attained, comparable to that of the M-version. Vignetting is more pronounced, with one and a half stops, and distortion too is more visible than with the M design."

Now here is where I'm not sure what he is saying. "The R lens was given better performance at the closer distance range, on the assumption that the R-system would be more frequently used in that range."

I think he means the R lens was given better performance in the close range than its performance in the far range; and that the latter (the far range) is less good than that of the M lens, perhaps having been sacrificed in order to improve the near range. But he could have meant that the R lens has improved performance in the close range, without meaning or implying that the R lens is any worse than the M lens at infinity.

I wonder how he meant that? User experiences on this point?
