Thanks a lot for the images Jan. I miss a bit a full detail shot of ā shifted corner, your shot show sky in the corner. This might be for most practical purposes not so important sometimes it certainly is. Stopping down to f16 isnt such great deal with the canons for their great long exposure possibilidades and for blurred people you can probably use f11 and iso800, but its clear that a rodenstock hr lens is the better choice, but the price. I will buy the 17& 24tse probably too as backup system at least its great now.
I don't think anyone is claiming this will rival a rodenstock hr or digital lens, a pancake style view camera, and a P45 or similar. It is a huge improvement though for dslr based work.
I've attached a corner crop showing the upper right corner of the right hand file that made this image
. 12mm shift to the right in this case. It's screen res, 100%, processed in Aperture with no additional sharpening added. You can see it gets a touch softer in the corner itself but it's a very small area of the frame if the image were to go to print. Nothing that couldn't be reclaimed with some localized sharpening, if that's needed at all.
