Tilt and macro work with Nikon PC 85mm
A quick test of tilt with the large PN-11 extension tube on the Nikon 85mm f/2.8D PC-Micro-Nikkkor was surprising: even at full tilt (12mm), there was no sign of vignetting at f/8. Apparently the tilt mechanism keeps the optics centered enough so that even going down to 1:1 allows full use of the tilt function.
