Hi George,
As always, there are plusses and minus:
1.  Lighter than the Hassy kit
2.  I had no synch errors between the lens and the back; something that 
happened with the Hassy (both Flexbody and 501). So the workflow was very 
3.  Wonderful to have horizontal shift and VERY easy to do with this body. 
just slides right over and has a click stop in the middle. Perfect!
4.  Using the LCC capabilities in Capture 1 Pro completely took care of all 
light falloff from going so wide. Wonderful addition to the RAW workflow.
5,  I cannot find ANY chromatic aberrations or purple fringing. How do it do 
6.  Leveling is easy with the built in bubbles.
7.  I've never been able to go so wide. Imagine a 35mm on a 6x6 and then to 
able to go 18mm wider on either side. And they make a 23! Crazy.

1.  Focusing using the Flexbody ground glass unit and Rmfx is not easy. 
not easy using any ground glass. I understand that you're best served using 
Leica laser range finder, but that seems pretty over the top to me.
2.  The hyperfocal markings on the lens are for film and not for digital. I 
to do testing to find out the true hyperfocal distances for various 
with my back and each lens. Not a big deal; just need to do it once...
3.  I will probably end up having to do some kind of focus stacking to get 
sharp from near ( 0.4m) to infinity. I'm not real happy about that. Would 
have tilt, but you can only start using tilt with an 80mm or greater. That 
an 80mm with about 10mm shift on each side turns into about a 55mm on 6x6, 
4.  The tiff file size with stitched images is big; over a gig... I can see 
where I'm going to need to cull and delete a lot of the bad images. Not sure 
this is a plus or minus.

Overall I'm completely thrilled. The dynamic range is impressive. The image 
showed is not an exposure blend; each of the 3 stitched frames is exposed 
the highlights with the shadows drawn out in RAW processing. That's pretty 
darned impressive if you look at that scene: it's about as contrasty as it 
Pointing into a sunset with the shadows on my side of the grasses.  And the 
detail and fidelity are just as impressive.

Next step is to get the hyperfocal distances nailed down and figure out how 
focus blend (probably Helicon Focus). I'm hoping that I'll still be able to 
sharp grasses in the foreground, unlike exposure blending where you can 
that sharpness due to movement between frames.

Thanks for asking. Good to put it in writing for me to see.

appears you and the gear get along quite well

so how does this solution "feel" in the field
compared to what you imagined
