Shots of a test chart at f:1.0 were shown side by side. *If* the shot with the Canon lens was *really* taken at f:1.0 (which is what they claimed), the Canon lens was clearly superior to the Noctilux at full aperture. It exhibited much less vignettation and showed fine details with more contrast. At 5.6 they were about equal. Beeing a former Noctilux-owner, the test chart of the Noctilux at 1.0 looked very authentic to me. I was not surprised to read that the Canon lens was appearently better. After all it is a very recent design that employs not only more lenses, but also aspherical lenses. And it has a significant larger diameter. Thus, it seems reasonable to me that in the Canon lens optical abberations are better corrected and vignetting is reduced as compared to the Noctilux. Nowadays, I prefer the Summilux-Asph. to the Noctilux, as I often needed a wider angle. When I compared pics which I took with the Noctilux with f:1 and 1/15s and with the 'lux-Asph. at f:1.4 and 1/8s, the Summilux pics were always better. The DOF of the Noctilux at f:1.0 is so shallow that the slightest move of the camera between focussing and the release of the shutter results in some unsharpness. So even if the Noctilux would perform great wide open, it would be very hard to get the same results without tripod. Of course the same is true for the Canon lens.
