 I am thinking of a field test for this defraction question. I have a Zeiss S-Planar 120mm F5.6-32 with a Hasselblad C mount and an adaptor to the D600. With the camera on a tripod ISO 100 and set to liveview, to avoid mirror shake, and arpeture preferred, a series of 5 exposures will be taken, one at each f stop using fine jpg. and raw mode, with the camera settings to their least enhancement mode.

I would appreciate some input on this test design and some ideas about what type of scenes, backgrounds etc. might be defraction prone as this high quality medium format lens in itself shouldn't be a problem, meaning any degradation of the images should be a result of sensor pixel density.
