I just received my copy of issue 300 (18 Dec 2007 - 18 Feb 2008) of Chasseurs d'Images from France today in the mail.
There are tests of three DA* lenses, the 16-50/2.8, 50-135/2.8 and 200/2.8. The 16-50 and 50-135 were rated 4 stars (out of five maximum) and all the flaws we have discovered and discussed here were what kept the two zooms to just 4 stars: CAs and distortion in particular.
The DA* 200/2.8, however, received the top 5 star rating. The very loose translations and extracts of the high points follow:
Vignetting: Negligible.
Chromatic Aberration: Present, but weak, detectable at 0.12mm (< 0.008 in) on a 30x45 cm (12x18 inch) print.
Distortion: Absolutely negligible. Bravo!
Resolution: This lens offers top level results, that only ask for tighter autofocusing by the camera body. As is, this lens will satisfy the most demanding users.
They also note that the SDM in the 200 is an annular or ring motor. I suspect that this means that only the K100D Super and K10D can use the lens in AF mode.
Predicted release: January 15th.
