Hi All. It's been a while since I checked in hope you are well. I have some
practical experience with what is proposed here re: trying to come up with
inexpensive WA lenses on 4x5, if that is the thread, and there is not much
of a free lunch here.
The 55 or 65mm lenses TLR mentioned will work, however the circle of good
definition- somewhat smaller than the max image circle- will prob. not cover
6x9 , more like the 6x6 they were used on. Might cover 6x7 adequately
stopped way down but I doubt it if there were any tilt or shift.
Of course the lenses made for the older "23" graphics will cover 6x9 and
even give you a little room for basic tilt and shift. You can occasionally
find a 65mm Angulon made in the 50's-60's for 6x9 but they are difficult to
focus, they were meant for press type use on Linhof with rangefinder more
than ground glass work. A bright screen or fresnel is a must although
sometimes makes it hard to focus with a wide angle....You occasionally find
a generic German 65mm 'Weitwinkel' on Ebay, apparently a pretty good 65mm
lens for 6x9.. they were sold by the NY discounters at the time.
The best thing I found that I think you guys are after is an 80mm Heliogon
or better yet, Planar off a Graflex XL. I don't know if that is wide enough
for you... it would be almost like a 24mm lens on a 35mm format camers.
They have a HUGE image circle, relative to the 6x9 format of that camera;
will paint a nice stripe across a 4x5 sheet almost edge to edge the long
dimension and to the top in the center and out some distance....in other
words every thing but the corners. I had some XLs once and tried it to see.
If you don't need a large image circle you could use a focal plane shuttered
"23" speed and the stripped, non-shuttered optics from an RB67 lens, or
maybe a Zeiss DDR lens off a Pentacon like a 50mm, they are quite sharp! and
much cheaper than the Mamiya 55....
Regards, S

Jim,
I think that I can save you a lot of trouble if what you want is an
ultrawide lens on a 4X5.
A police officer friend of mine takes Mamiya 6X6 twin lens lenses and
separates the viewing lens from the lower taking lens, (just unscrew the jam
ring from the rear of the lens and remove it from its lens board), and
mounts the lens on a blank 4X5 lens board. This way you have the leaf
shutter intact and can use any 4X5, Crown or Speed Graphic body with all of
the front standard's tilt, shift, and rotations. There was even a 55mm
f/4.5, or 5.6 lens available, which on a 4X5 is pretty much a 15mm or so
lens!! Attach a 6X9 rollfilm back and you have something.
I have a 2 1/4X3 1/4 Century graphic wiyh a graphlock ground glass back,
as well as a 6X9 rollfilm back. The standard 101mm lens fully covers the 6X9
format with no vignetting!!
The nice thing about the Mamiya twin lens, lenses, is that they can often
be found cheaply, because oftentimes the viewing lens is FUBAR, but thye
taking lens is OK, and that is the lens that you are really after.
I told you guy's that I'm an incurable gadget freak.
