I love shooting medium format, but I'm getting tired of the 6x6 format and looking to get a 6x7 format camera. I'm looking for something that comes as a system, is fairly lightweight for travel/walking around, and is very handhold-able (I rarely, if ever, use a tripod). Right now, I shoot with a Hasselblad 500cm with 80mm lens, and it's about the perfect weight for me, and I carry it around everywhere. I did try a Pentax 6x7, but it was so huge and unwieldy that I ended up selling it. So right now I have it down to a choice between a Mamiya 7 and the Pentax 67II. I do prefer the closer focusing and dirt cheap lenses of the Pentax, but the Mamiya has the advantage of less weight and size, superb glass, and leaf shutter lenses. Unfortunately, I have no way to test out the cameras before I buy. For those who have tried both, which would you recommend as a travel camera, especially for landscape or street photography? Is the size and weight of the Pentax 67II much greater than that of the Mamiya? Any input would be appreciated.
