Wista-Mamiya DIY Hybrid – getting closer to the perfect wide-angle camera (2013)

As you may have gathered already, I am rather a wide-angle photographer…
To get on with my search for an ideal wide-angle camera, I have even put down my requirements and what the different camera concepts have to offer as a table - but since it is in German it is of not much help to the English speaking part of the world (it didn't help me much either...)

I went a long way to come closer to the ideal, I have e.g. converted a Graflex Century Graphic to the
Mamiya Press mount

Too flimsy and restricted to 6x9 (6x12 was always in the back of my mind)

I then tried to modify a Shackman oscilloscope camera

Please note the nice instruction “This part may be rotated in either direction”
This beast offered enormous shift capabilities, but was very heavy and a little inelegant.

I Eventually gave myself a Wista VX 4x5 camera, with which I spent my summer vacation:

The Wista is a 4x5“ field camera, a foldable flatbed camera, which I operated with a 6x9 (2x3”) roll
film back and a 150mm Schneider Xenar, a 65mm Schneider Super Angulon and certainly my trusted
50mm Mamiya Press lens. To be able to see at least something on the ground glass, even with the
wide-angle lenses, I fitted a special Fresnel screen from Ebony, which improved the situation a little,
but not by much. A bright image “from corner to corner” seems difficult to achieve.

Still a very pleasant photographic experience! Relatively easy to carry, very solid, a fine way of taking
pictures – with the one exception that operating lenses with a small register is tedious or even
impossible, and those tend to be the (wide-angle) lenses I love… 

To be able to use at least some movements on the 50mm Mamiya and on the 65mm Super Angulon, a
wide angle bellows is needed, which is (or was) available for sale … in theory. In practical terms, this is
an accessory very hard to get. The leather wide-angle bellows I fabricated myself indeed allows for
those movements at very small extensions, but happens to be too bulky to allow closing the camera
properly, unfortunately…

As likable as the Wista is, this is not perfect, again.

So, what would eventually be my ideal?

* Being able to use international 4x5” backs, including a 6x12 back (the largest format I
am able to scan).

* Being able to use Mamiya Press lenses

* Tilt and Shift possible even with lenses with registers a small as that of the Mamiya
press lenses

* Reasonably priced and rugged enough to be taken outside

Since the Wista can easily be dismantled, the use of the rotatable back was an easy choice, as well as
that of the front lens standard, which allows generous movements. Mamiya Press lenses can also be
mounted, in a lens board made from sheet aluminium and a Mamiya Press close up ring.
Unfortunately, the – beautiful – Horseman cameras cannot be used for that, because their lens board
size is too small to take the Mamiya Press bayonet. 

The „In Between“ I had to make…

There even was a Lego brick fixture, again…

The flange for the rotatable back of the Wista is pretty ingenious, and cannot be replicated at home (at
least not by me), so I had to look for a simpler solution. Eventually, after numerous brainstorming
sessions, I went for a “slotted” opening, made from 3mm aluminium sheet metal.   

After inserting the back, the top opening is closed with an interlock, pushed into place. It remains
possible to turn the back, for an occasional portrait format shot, and the back certainly doesn’t fall off.

On the other side, the wide-angle bellows has its place, and the two angular rails (filed with love) wait
to take on the Wista lens standard.

The lens standard does not need to be moved very often, since the Mamiya lenses have a focusing
helicoid. All that is needed is a mark on the rails.

I have tried to make the wooden body as shallow as possible, to be able to access and operate the lens
movements as good as possible. This is as narrow as I could get it, and it indeed allows relatively easy
operation as opposed to the original Wista, where I almost broke my fingers.  

The whole thing is is still pretty heavy, 2200g with 65mm lens and screen, which means that with two
additional lenses and some accessories, your bag weighs over 5kg. But at least the weight is less than
that of the Wista, one third less for the camera alone. Even the occasional handheld shot seems

I own three Mamiya Press lenses currently, all of them allowing sufficient movements on a 6x9 format.
The 50mm does not quite cover the 6x12 format (it vignettes a little in the corners), the 75
has no problem at all.

On a 6x12 format, the 50 mm lens offers an enormous angle of view (equaling a 15mm lens on 24x36),
but even the 75mm lens offers the view of a 23mm lens on 24x36 (horizontally).
