Ok, so after attending Nicole's workshop in Toronto, and feeling very inspired, I have decided to take the big leap and use film exclusively - not only for personal work, but also for my business (believe me, this is no small decision). I've been wanting to do this for a while but after attending Nicole's workshop I finally feel ready to really "shoot from the heart." So...I currently use my Hassey for most of my personal portrait work. Now that I will be shooting film with my clients as well, I would like a non-square medium format camera as well. I do not want a 6x7 format as those cameras are simply too much for me to carry. I do have a Mamiya 7II but that is not, for me at least, an ideal portraiture camera. After seeing Nicole, I am leaning towards perhaps a Pentax 645NII. However, before I make the leap, I also would love to hear of others' experiences with the 645 format - I also am considering the Contax 645 and the Mamiya 645 (the AFII or III). I'd love to hear some feedback from those who have any one (or all!) of these cameras. Thanks in advance!
