Phillip - I also really enjoy what you're doing with the CV15. The last indoor image has a great feel to it too!

Derek, I do enjoy the rendering of the Luxes wide open and/or close to. The OOF is so very Leica-ish
me too, it's quite a unique look that i've always been fond of.
i'm still getting a handle on how the lens performs it seems to have very little change in exposure or dof stopping down from f/1.4 to f/2, rather the glow just changes a bit. it does have significant focus shift at medium distances. i've been surprised to find out that it's actually pretty sharp wide open at infinity across the frame with none of the field curvature issues that the 40 cron has (at least on aps-c ). at near and medium distances sharpness seems to drop off a cliff outside the central third. at some point i'll have to compare it to the 40 cron and c/y 35/1.4 but my initial impression is that it has a very different draw than both. the lux stronger SA that doesn't go away until the lens is stopped down considerably more than the other two would need to be. it also never seems as bleedingly sharp as the other two centrally though that may be more of a contrast thing than a resolution thing. on the other hand it seems much better behaved across the frame than either of the other two and is thus probably the best landscape lens of the group.
Derek: interesting observations. I also like the look you're getting from it. Maybe there is something to that supposed Leica-glow after all?
My only Summilux experience is with the newer ASPH lenses but there seems to be some consistency to them as well. Infinity performance, even wide open, seems to be quite good for the class. I've read that many of these lenses are infinity optimized. I also find they're 'dual personality' lenses. Wide open character tends to be sharp but somewhat gentle, while stopped down resolution/contrast is extremely good. The 50 Lux ASPH, for example, also exhibits a fair amount of SA at 70cm, despite being a floating element design. I've found the CV50/1.5 and ZM50/2 outperform it at this distance. It could be some non-ASPH Summiluxes share similar traits, but perhaps more extreme. It might also be a matter of design to match imaging technology of the era - film stocks, printing and reproduction techniques, etc. Not sure if you follow discussions about the Leica Monochrom, but it seems many are finding older lenses offer a gentler image quality that allows for a lot more flexibility in post compared to modern, very high contrast lenses...
On another tangent, here's an image with the NEX-7 and 90 Summarit. Toronto Union Station.
