My Carl Zeiss Contax 85/2.8 has so much "Zeiss 3-D effect" that over the course of focus bracketing during a test at f/5.6, it forcefully emancipated my ISO 12233 test chart from the cramped confines of two dimensions.

This'll make it difficult to test my other lenses...

The shape it formed is a hyperbolic paraboloid: for those without the benefit of such an awesome lens you can make this shape manually based on the instructions at this link:
