Hello, I am considering a project in which I will need a camera that can shoot vertical (or square format) shots from stomach height while walking, has a lens with an approx. 90 degree AOV on the long dimension (about like an 17 - 20mm lens on 35mm), and has a flash synch that will allow fill flash in daylight. I am willing to use small format, but medium would be preferred. I could also use large format, I suppose. This is what I am thinking of so far: - Speed Graphic w/ 65mm or 75mm lens, hung sideways from the flash brackets with preset focus. Would need to purchase 65mm lens and board. I already have a 75mm Mamiya press lens that I could try to mount. ( I don't mind some vignetting.) The 75 would give me about the horizontal AOV of a 21mm on small format. Not too shabby. - Rent Hassy SWC. Still not very wide at about 75 degrees AOV - 35mm lens on Mamiya M645 held sideways. Kind of a hassle to have to hold sideways instead of letting it hang, and 35mm is not quite wide enough for what I think I want. - Blackbird, Fly (33mm lens) with accessory wide lens. Which accessory wide lenses might work? - Rollei Wide 55mm with accessory wide lens. Which accessory lenses might work? - 17mm lens on 35mm SLR held vertically. '60 flash synch is a likely problem. - Borrow a friend's EOS 1 and 17-40 zoom. Flash synch speed is better on this one, and at least it has a vertical grip and can be hung vertically. The problem is zone focusing with this lens, which, like any AF lens I've ever used, has a near-useless focusing/DOF scale. I also have Mamiya C and RZ systems. Is there a rectilinear lens for the RZ that is wider than 50mm? Their 30-something would be perfect, but it is a fisheye. Super sharpness is not necessary, but I also don't just want a totally fuzzy image.
