I just shot a stack with it at 3x using an MFT camera (FF camera would have toppled my setup-- a vertical view camera at full extension clamped on a marble vertical support, with a tall tower of shaky extension tubes between holding the MFT camera above the back of the view camera). Looks pretty good, especially after processing. I can do better with other tools at 3x on MFT, but it is staggering to think that this level of detail is actually present throughout the giant 100mm+ aerial image. On medium format this would be an exciting lens at or below its rated magnification.
PS. Robert, pardon the dust (er, astigmatism detectors jeje).
