The Mirex came, the Mamiya 50mm Shift came, and the Novoflex came - it was like an early Christmas here in Miami :-)
I am very impressed with the Mirex. It is their latest version (recently updated and upgraded) of the Mamiya 645 to EOS. The machining and manufacture of the adapter is very high end. Quite impressive. Gears would be nice, but the product is top notch.
I then adapted the Mirex with the Novoflex EOS-NEX to fit on my Sony A7rII.
The Mamiya shift lens is a nice lens to hold in the hand. The gear driven shift mechanism works smoothly. There is a tiny bit of wiggle when it is mounted to the Mirex, but nothing serious I think.
I had a pretty busy day, so I couldn't devote a ton of time to this test, but I had to give it a whirl. I attached the camera in the portrait orientation, and took it to my front yard, and aimed it at my neighbor's house across the street. The camera was leveled, and the shift mechanisms were zeroed. I shot the center frame, followed by a frame shifted to the right 15mm on the Mirex, then to the left 15mm on the Mirex, next, I shifted the Mamiya lens itself to 10mm, and added that to the 15mm on the Mirex and shot two more frames, one extreme left, one extreme right.
The aperture was f/16.
In lightroom, I post produced the files as I would normally. A bit of clarity, sharpening, white balance, the usual set. I also removed some green and red fringing using the tools in Lightroom. Next, I used Photoshop's auto align, and auto blend functions, and that was the end of the experiment.
The results are a file that measures 16238 x 7787, basically a 1:2 panoramic. The field of view on this 50mm lens after all of this crazy shifting and stitching is a touch wider than my 25mm Batis FE prime lens.
When pixel peeping, this is not the absolute finest image quality I have seen, but I must say, it's pretty darned good! That, when considering the extreme amount of shift, 25mm in either direction, is saying quite a lot. The Cambo Actus gives 20mm of shift, and most tech cams will not shift this much. I think I have found the tech cam solution on a shoestring budget. $1000 for the 3 items, and I have a 127 megapixel image on the Sony A7rII.
I saved the file and loaded it for any of you to view and download in full res. Here's the link to download the full res version saved to JPEG level 10 in photoshop:

When I get some time, I will take this to a cool location where I can shoot some architecture and do a more controlled test, seeking for the optimal sharpness with aperture, and get a more interesting image. I have to say, if you want to print large, the combo of the Mamiya 50mm shift and the Mirex looks like a match made in heaven.
I now want to see if I can get an image as sharp as one of my older shots on a Hasselblad 501 camera, Hasselblad 50mp digital back and Hasselblad wide angle lens (I had the 50 and the 40 IF back in the day). I've printed those to 44x60 inches, so as long as I can best that, I will be quite thrilled! More to come...
