Subject: Anyone using Ultra-Wide lenses
Date: 2011-06-15 11:33:58
From: coronet3d
I'm curious to see if anyone is using a very wide lens for MF3D, like for instance Hassy's 38mm kit, on a slide bar or twinned. I would think it would be hard to twin these monster lenses, but again I'm curious to see if anyone out there is doing it.
Thanks,
Steve

Hmmm. I'm shooting mamiya 55mm lenses, but that doesn't
really count as ultrawide.

If you wanna set me up with some Hasselblads, a pair of 38mm
lenses, a suitable tripod, and a sherpa to help carry it, I
have some images I'd like to try :)

If you do shoot 'em, do you have any special plans for
viewing 'em?

    Well, I’ve played with a LEEP camera and I have a 40mm lens for my Hasselblad, but very wide-angle stereo is MUCH harder than one thinks it should be…

    Some time ago, I shot some single-camera slide bar stuff for a client using a 58mm Grandagon on a 4 x 5 Sinar view camera (field angle comparable to a 25mm on a Hassy, if you could get one).   I was startled at how well it worked, exceeding my expectations.   One of the products shot had a long metal bar protruding, and it came way out into negative space, while the background some 300 feet away (an after-hours factory with big machines, sans people, in a large building) was a very comfortable low parallax to view.   In fact, the amount of apparent depth attainable, consistent with the very small amount of measurable screen parallax was really surprising.   I shot a variety of stereo bases (I also wanted to use them for lenticular, as well as stereo pairs).   The circle of the field of the Grandagon on the 4x5 just covered corner-to-corner, such that if I shifted the lens center by only a couple of millimeters, there was vignetting.

    Sure, I shoot with twinned Mamiya 7's with 43mm fl lenses, I linked them electronically
    and have a single exposure button. They are by far my best MF shots.... the lenses record
    about half the deviation of normal 80mm lenses, but min. taking base of 165mm records 3x
    more deviation than a standard 65mm base, so you get a bit more punch than normal, (about
    1.5x factor) but not so much its difficult to fuse....
    I also shoot with my 47mm fl digitar stereo camera..

    Bob, what is problematic about WA lenses? Yes, Super WA creates some problems, such as my
    16mm fl on 35mm.

    Well, I guess I was remembering when I was using 17mm on 35mm SLRs...

    And, the LEEP is quite hard to compose for - you really don't believe just
    how close you have to go in!

    I'm pretty sure that any lens for an MF SLR shorter than 30mm is a fisheye. Of course there are some oddball lenses like that Goerz one with the spinning wheel in front, but those are exotic rarities.
