FA24-90

Vignetting very moderate, well controlled chromatic aberration, very good distorsion for a zoom, performance OK at 24 and 90mm but very acceptable. High performance between those focals.

Rating 4/5

FA* 28-70/2.8

Vignetting not negligable at 28 and 35mm, very slight chromatic aberration, very good distorsion, Very good shrapness at f/2.8 and exceptional at other focals.

Rating: 5/5

FAJ 75-300

Vignetting almost inexistant, chromatic aberration heavy from 200mm and very noticeable at 300mm, good distorision. Sharpness: focussing difficult at longer focals, f/11 is a minimum to have acceptable results at 300mm.

In general, it is no match for the K20D: to avoid !


FA35/2

Vignetting: very good even at f/2, chromatic aberration very slight, distorion very slight, Sharpness amazing: soft at f/2 (some focussing unpreciness), good from f/2.8, excellent at f/4 and up.

Rating: 5/5

FA50/1.4

Vignetting present at f/1.4 but almost inexistant from f/2, moderate chromatic aberration, distorsion almost nonexistant, Sharpness amazing: decent from f/1.4 (precise focussing), very good at f/2 and excellent from f/2.8.
