Introducing the Mamiya 50mm f4 shift
( sorry for the various badly taken shots )
Here is the Mamiya 50mm f4 shift on my Mirex T/S adapter. Even though the lens is pretty heavy, the Mirex adapter holds it quite well
No automatic aperture on the setup which is to be expected really.
Light falloff is extreme at extremes of shift. Double shift with the Mirex to the extreme is not useable. Lens itself shifts 15mm to edge, the Mirex adapter makes another 15 mm shift giving a theoretical 30mm either ways which is huge. But practically speaking, I will only go up to 25mm max in total. I usually centre the lens unshifted and shift to the maximum on Mirex, then extend the shift on the Mamiya to add on if any.
Ok at f4, but shines at f8 +. For tilt at f4, sharpness is satisfactory, the 85mm f2.8 PC is a little better wide open
Here is a quick and dirty pano of my neighbourhood, which is what you get at full shift on both adapters and the lens. I have not had a need to do such a long pano so far.
True value of setup is it allows independent shifts when the lens and the mirex adapters are fixed with their shift axes perpendicular : eg, you can shift by a certain amount on x axis and a certain amount on y axis.
Here is a recent example taken in Macau:
I was a little too positioned to the right, and i shifted horizontally leftwards to centre on the scene, and an upward shift to align the tower
As like the other old Mamiya lenses i tried adapting for tilt shots, they typically produce softer oof blur compared to my previous experience with Nikon 85mm PC and 24mm PCE.
