DA*200/300:

Precise focussing, exceptionnal performance, almost no vignetting, chromatic aberation or distorsion at all. Performance level exceptionnal. Very good mechanical quality.

They say it can not be compared to a high level bright zoom: those are much better.

Rating: 5 stars or out of 5 for both lenses.

DA21:

Marked vignetting until f/5.6, chromatic aberation visible but OK, distorsion visible but workable (forget architecture pictures), performace OK wide open, excellent by f/5.6 and up.

Rating: 4 satrs out of 5

DA35 macro:

Vigneting visible wide open on bright background, this is the only negative point of this lens. Very sharp, focussing ring very smooth, very good mechanical quality.

Well simply they love this lens. 5 stars out of 5.

DA40

Moderate vigneting, no chromatic aberation, very moderate distorsion. Very sharp performance from wide open to f/22. Nice smooth focussing ring.

5 stars out of 5.
