With my reference to the earlier comments I made on EOS 1Ds (Canon digital camera,in case someone who don't know) and ND (Contax digital camera), ND is still the best in terms of colour reproduction (despite it has reaches the end of its production) and free from chromatic aberration,thanks to Carl Zeiss optics. EOS 1Ds leads ND in terms of image resolution because it has higher pixels.
It would be nice if someone could tell us the result of matching EOS-1Ds with Zeiss manual lens thro' the adaptor ring(with the loss of automatic diaphragm mechanism}. I believe it could produce images with even higher resolution and colour reproducibility than EOS-1DS with canon lens.
If Contax is still using the N-series to race with others,she has to produce a digital camera with a higher pixel comparable with at least the 1Ds. Although Contax is always slow in the developments of the "pixels-electronics",at least she is always ahead of the others with the optics. Good optics take a lot longer to develope than good electronics.

I'm going to get off subject here. The post Kaisern just made about Zeiss glass and Canon L glass reminded me of something I read on a web site recently. I don't know if this is true, but I can see some logic in the idea. The site owner said that in the early days, Canon tried to more closely emulate Zeiss glass, while Nikon was trying to emulate Leica. That might explain why if I have to choose glass other than Zeiss, I do prefer Canon L series glass. (Had L series for many years before selling it and loved it). I've had Nikon, but didn't care for the characteristics my photos showed. While on the other hand, my good friend loves Leica and also collects old Nikon gear. We do not share opinions on what makes a photo look pleasing 
I wonder if there is some truth to the assertion about Canon following Zeiss, and Nikon following Leica? Anyone? -Lynn L.

After reading Kaisern Chen's experience,what I predicted could be right. Mr Chen mentioned about colour fringing on Canon lens but less obvious on 85/1.2,100/2 and 135/2.I suppose the last three are Zeiss C/Y lens. It does suggest Canon L-lens have the problem of chromatic aberration and this is not found in Zeiss lens. Chromatic aberration in 1Ds could be solved by changing the lens to Zeiss. Zeiss lens owner should be pleased.

I somehow had the impression that one of the problems in using standard film lenses with digital sensors was the fact that the mechanical structure of the digital sensors (Foveon excluded) in which each sensor element is slightly recessed in a little box doesn't respond well to light reaching it from other than head-on, that is normal incidence. Is this a factor?
