Personally, I think more than the body, you should be looking for the best lenses. I can only comment on Contax. I had a Contax 139Q that I worked pretty hard until it died on me. I can't attribute that to any Contac unreliability as it was right after a house fire and house fires wreak havoc on electronics. But the 50mm f/1.4 is a superb lens. I currently have a Contax 167mt, which actually seems to fit my hands better than the 139Q, and isn't as heavy as one might suspect with its motor drive. But if you decide to go for a lens line, your next problem will be ensuring you get one that is still good. My two Contax 50mm lenses have held up well. But so have all my Fujinon lenses.
I am surprised that you would want to use 35mm for portraiture, especially since you only want 28mm and 50mm. I know you can use any lens for anything, but some are pretty well acknowledged to work better for different things. Above suggestions for a longer lens for portraiture are at least worth considering imho. I would also wonder why you would not want a MF for both landscapes and portraits. What do you use now?
But that said, I have used 35mm cameras for everything you can imagine at different times myself. Not knowing your style or clients, I have to guess you know very well what you are doing.
