Thanks, that was a quick response. Also a brief answer to a long question (no bad thing). I use a Minolta 5400 scanner and this gives me the equivalent of a 39 MegaPixel image from 35mm slides and negs.
I use Contax and Zeiss because I don't want my equipment to be the reason I take poor pictures. Don't know too much about Canon except my perception is a bit plasticky (maybe true or not) and heavily reliant on button pushing (which I hate), nevertheless Canon have good reputation when it comes to performance and can take my Zeiss lenses.
I would be looking for full frame DSLR, I'm more interested in wide than tele and wouldn't want to lose angle of view of my wide lenses. Also looking for high MegaPixel count as I'm used to same from Minolta scanner (yes I accept there are losses from capture on film, through processing and then scanning, but 20 MegaPixels is about as low as I would go).
As you can see, I've spent too much already and would probably use the sale of either C/Y or N system to pay for DSLR. But this means that I don't have unlimited resources, so I'm looking at 20 MegaPixel minimum, full frame and hopefully, comfortably under Â£2,000. (Don't mind secondhand at all, most of my gear was purchased secondhand).
Will have to look into mirror issue on 5D MkII as I know this raised certain issues with Bo Ming's N mount Conurus conversions. I understand however, that these were all resolved.
As far as C/Y mount on 5D MkII, is this an issue dependant on which lens you use, or is the type of adapter an issue?
The main question is, bearing in mind what I might like to do in the future, which of the above kit would you keep if you were me?
