The Minolta AF 1.4/85mm has rather pronounced spherical aberrations. Wide open, the lens displayes lots of detail, but the overall microcontrast is quite low.Stopped down to f2.8 the contrast increases to normal values, and the focus slightly shifts backwards - this is a consequence of the undercorrected spherical aberrations. For portraiture, these characteristics can be quite useful. Skin details have a pleasant appearance - they are visible, but they don't distract from the overall image.
	The Zeiss Planar T* ZA 1.4/85mm is slightly harsher wide open, and stopped down we observe a slight front-focus.
	The Minolta AF 2/100mm has well corrected spherical aberrations and a characteristics similar to the Zeiss 1.8/135mm. Detail resolution and contrast are very good at f2, and excellent from f2.8 onwards.

The two following series are details from St. Peter in Rome (Italy).

We can see that the remaining spherical aberrations of the Minolta AF 1.4/85mm are stronger than those of the Zeiss. Nevertheless the Minolta images look more pleasant to me: Used wide open, the lens causes highlights to "glow" from inside; the Zeiss images at f1.4 look somehow dead. Stopped town to f2, the Minolta AF 1.4/85mm is at least as good as the Zeiss, and the Minolta AF 2/100mm. At f4.5 all three lenses are simply outstanding.

	Images of the Minolta AF 1.4/85mm can have a very pleasant, shiny look ("The Glow") if the lens is used wide open. Stopped down to f4.5 the lens becomes outstanding, both regarding detail resolution and microcontrast.
	The Zeiss has much less spherical aberrations, and much less Koma as well. Nevertheless, at f1.4 the Zeiss doesn't look as pleasant as the Minolta. At f 4.5 the Zeiss images are as crisp and detailed as the Minolta images.

BOKEH: It is quite a surprise to see that the Zeiss 1.4/85mm bokeh wide open is clearly better than the Minolta 1.4/85mm bokeh. In the past, Zeiss lenses often were criticized beacuse of their harsh background blur, but obviously they know now how to do it better.

Stopped down to f2.8 and further, the bokeh of the two lenses becomes very similar.

COMA: The Zeiss 1.4/85mm is clearly better than the Minolta 1.4/85mm - especially wide open and, to a lesser extent also at f2.
From f2.8 on the differences are neglectible.
