[LargeFormat] Reflex viewer question

[Jim Hemenway]

Gents:

I really like shooting with a fisheye lens and wanted to try a larger 
format than 35mm and medium format, but couldn't find a lens which will 
give me fisheye effects on large format.

So, with the encouragement of Glenn Barry, I built this with a lens that 
I had in a drawer. <http://www.half-fast.com/Fisheye/4x5-Fisheye-L.jpg>

It's a 4x5 Fisheye camera with an 85mm image circle.

I used an old beat-up Speed Graphic which I stripped down to just the 
box and the focal plane shutter.

Then I killed an ailing Kiev 60 to harvest its body parts.
<http://www.half-fast.com/Fisheye/Kiev60.jpg> to get a lens mount for 
the 30mm fisheye lens which I then installed on a piece of wood which 
fits tightly into the camera box.

This is what it looks like from the side:

Here's some of the first photos from the week before last:

You can see that the "ears" of the built-in lens hood, interfere with 
the 180 degree sweep of this lens when used with this "camera".

So I used a pair of tin snips to remove them:

These photos are from this past week without those pesky "ears":

I had forgotten just how much "real estate" is seen at 180 degrees, so 
this is me, not part of the lens hood at the top:

I've just received a Graflok bought on ebay to replace the decrepit 
existing spring back. I've already installed it and now I don't have to 
use heavy duty rubber bands with the Polaroid back.

Now I have to do some shooting with it to determine how to get the best 
photos out of it, versus a square or rectangular fisheye format.  Maybe 
someting like this:

OKAY, now for the QUESTION:

Does anyone know if these Sinar reflex viewers will work with the 
Graflok back?
