You said the "last generation Lux" which means the Summilux-M 35/1.4 asph FLE in my book, and i say no indeed. And you said the "35 Cron" which means (i guess) the Summicron-M 35/2 asph and i say no again, see above.

I am currently selling a 35mm summicron ASPH, so have one again at home. I have just experimented to compare with other 35's and see no focus shift close up ( just under 1m away)

 

F2-f5.6, full image at f5.6 M9-P and then f2,2.8,f4,f5.6 with an old tripod I only use for things like this

Sean Reid reported that his 35 Summicron asph shifted focus at f2.8 and f4. I tested mine and it exhibited identical performance. Focus shift on fast wide lenses is not limited to those like the 35 Summilux asph, although that one gets more attention.

 

However, as a practical matter, i.e., in prints, I don't have any real problem with the Summicron.

I am surprised and disappointed to see definite softness in the image center at the f 4 - 5.6 range. The image is fine away from center all the way into the corners. At larger apertures it seems OK and it is fine again at f8

Hi Frits, can you post a photo of that just to see?

thanks!
