I am really new to the idea of getting a digital camera. I've been using a Contarex for almost 50 years, so it may be a while before I get a digital. I realize that the cost of 24x36mm sensors is very high, but I would like to know what current models are available in "full frame". And what models might be produced in the next 2-3 years. Is there a chart showing the full frame models currently available, along with the multiplier for all other current (and older) models? I am specifically interested in getting a DSLR. The reason is that I would like to use my Contarex lenses on a DSLR, so of course a full frame model would be ideal. There is also a problem with adapters; the only one available, apparently, is for the Olympus cameras, and they have a 2x multiplier. (By the way, why do they call them 4/3?). I would like to communicate with people who have used vintage lenses, especially the Contarex lenses on the Olympus E-330 or similar. I realize it won't provide autofocus, but I would like to know how they work in actual practice, and what other difficulties have been encountered. In advance, thank you for your comments and suggestions.
