    The 37mm rb fisheye is excellent and will work on the rz. Way more than 90 degrees!!! But if you crop down to 90 you'll not be disappointed! An especially good solution if you are open to electronic corrections later.

    Let's see, the rb 50mm on the rb with 6x8 back might get you close to 90 on the vertical, probably just short.

    The mamiya 645 28/4.5 will get you past 90 and I suppose that you could mount it on a pro or similar with waist level. Very pricey lens, that.

    I guess you could scale focus a crown graphic with a 90mm lens, using either 4x5 film or a 6x12 rollfilm back.

    Actually, 37mm lens on 60 mm of film only gives a 78 degree angle of view. The 28mm lens on 60mm of film does get you to 94 degrees though.

    Not when it is a fish eye lens.
    Will be more like 112 degrees over each side, won't it?

    A rectilinear 37 mm lens on 6x7 will just be short of 90 degrees over the long side. It will only take 1 mm less: a 36 mm would be there exactly.

    Another thing I could do: rig up my own Sinar Handy- type thing using a back, carrier frame, lensboard, and shims with the 75. The only thing I would have to procure would be a Sinar lensboard with an extension. Too bad I don't have a 65, but I will see what the 75 looks like.

    I am looking at obtaining approx. 90 degrees on the long dimension of the frame, not diagonally. That means on a vertical shot, 90 degrees top to bottom. Any more would be too much, and I don't want a fisheye. The pictures will be printed analog with frame edges, and there will be a lot of them.

    It would be really great if there was a way to rig a wide accessory lens to my Rollei Wide or to a Mamiya C-series 55mm lens. A 0.5x on the Wide (or the Blackbird, Fly) would work perfectly.

    Hmmm, interesting. I guess I don't really understand the geometry involved with a fish-eye lens. How does that work?

    Brad, the fisheye gives roughly 180 degrees on 6x7.

    I use the lens a fair amount and like it a lot. It's shockingly good.

    Good morning 2F,
    My choice would be the Graflex XLSW with the 47mm lens. My second choice is the Hasse SWC with the 38mm. It hangs well on your midsection and is very compact in size.

    The only lens I own that gives a true 90 deg. AOV is my Schneider 47mm SA with a 6x8mm Graflex RH-8 film holder (not exactly a true 6x8 format, it's 5.75 x 7.8 mm).

    Thanks for all the thoughts.

    I temporarily rigged up my Mamiya Press 75mm lens to the Speed today. At six feet from a 6'2" friend, with the camera just above waist level, he was in the frame head to toe, and plenty sharp even at f/5.6. The lens covers 4x5 quite well. Couldn't get a great view of the corners just holding the lens in place. I have a gross or more of Press 25B and G.E. # 5Bs I may use.

    I used a 5x7 Hobo camera with a 90mm lens and it worked quite well the way you describe. Fixed focus and walking around shooting from the hip. I have a 65mm Super Angulon that covers 4x5 that I am trying to sell, but if it doesn't sell I was thinking of making my own version of the Hobo to use it on. Or I could put it on a Speed Graphic, but then I'd be tempted to focus.
