If I decided to give the 645 a try would I find that anything was lost in comparison to the 35mm in practical use. Landscapes, travel, product photography? The Pentax 645N is so reasonably priced now that I have been seriously thinking about giving it a try. This is one of those questions where I may not be asking the right question. I am a digital shooter that started shooting 35mm and now i am thinking about MF.
