They ask for an SDM version. Superb lens but mechanical quality so-so...

Rating: 5/5

FA*85/1.4

Very noticeable vignetting at f/1.4, less at f/2, never null but negligable upward. slight chromatic aberration, performance OK at f/1.4, very good at f/2 and excellent from f/2.8

Rating 5/5

FA 135/2.8

Vignetting negligable, amazingly low chromatic aberration, no distorsion at all in practice, excellent performance from wide open, diffraction dimishes performance at f/22. They like it very very much

Rating 5/5.

Please Pentax, give us DFA 135/2.8!!!

The anti terror squad really didn't appreciate my argument that fetching my copy of chasseur d'images could well be worth the risk

I think Pentaxian are a group of fanatics they have not considered yet...maybe they will start to do that now
