what is the Summilux 35mm pre-asph? how it acts on the M-P 240?

by damonsong, on FlickrI can compare with the 35mm v4 CRON and Zeiss 35mm f2 (which is equal in performance to the Leica 35 asph f2, albeit with better distortion).
The 35/1.4 Lux pre-asph (German made version) has no problem with using on a M digital. The profile exists in Leica M bodies => coding is not an issue at all.
At f/1.4 the pre-asph lux image is finely defined but with some glow in the finest structures.
At f/2, it's much better and already sharp, not as sharp as the summicron v4. However it will still equal the previous 35mm summicron versions.
At f/2.8 it's not as clinical sharp as the summicron v4 or the Zeiss, but not much to split them. Despite being less sharp (on a M digital), I prefer the summilux image because it won't bring moiré as much as the other lenses : lots of time saved in post processing.
At f/2.8, not much for the pre-asph summilux user to complain. Will remain less sharp than the cron v4 and Zeiss but not enough to justify one over the other.
From f/4, the summilux has a better resolution than the Cron v4, but not as good as the Zeiss and I suspect not as good as the Cron/Lux Asph.
A great advantage of the pre-asph lux over the modern asph is their zero-distortion.
Drawback: 35 lux (as well as 50 lux) lenses will exhibit a focus shift on M9/M240/M depending on the aperture and the distance. Each lens may behave differently depending on how the designer or serviceman has set up the sweet spot of the lens. This wasn't a problem with film-M's but definitely is with a digital M. I can confirm this from my renewed experience on a M9 serviced less two months ago service at Wetzlar.
Only solution not to be bothered, use summilux FLE lenses or digital-orientated summarit lenses.
I did a comparison recently between a early version 2 Canadian Summilux (in fairly poor condition including a couple of meaningful scratches on the rear element) and a version 2 Canadian ...
I found the v1 render overall better than v2
Yes, I agree, but the v1 is therefore much more expensive.

Erik,
I have the V1 and V2 but never did side by side comparison (did not intend to anyway).
Although I did sometimes feel that when I use V1, but I have never been sure. so I got that feeling mostly based on your post, your posted photos from v1 was very nice.
Also saw it was said that v1 has 9 elements? Are you aware of anything like that?

Would you kindly do a quick comparison? I can't find any information out there to compare the result of them in detail. Very interesting!
Careful! Some examples of the pre-aspherical Summilux cannot be used on some Leica digital M bodies. If it has the thicker rear element shroud, it can scrape against the inner baffles of an M9, when focused toward infinity.
What are you looking for?
I could do it but I need to know what kind of detail are we targeting.
