So dear to me was my first version, this is better.
Even at full aperture as sharp as I could expect for the elderly most at aperture 5.6 to 8. FIG.
Fade Out brings the image quality was not much then except to the edges, the pick of a very high level already open just a tad bit towards the middle.
The sharpness reached a level that I'm used to from my 70-200 / 2.8 IS II or 135 / 2.0, or by 35 / 1,4 dimmed to 2.8 to 4. FIG.
(No, my Me Fixbrennweiten. Aperture 1.4 or 2.0 open a completely different chapter for me!)
For design: plastic, namely quality, but plastic. Already feels different.
It is shorter, noticeably; The extra thickness falls haptic not on, but very well in the wallet: filter with 82mm diameter are required.
(For me so a new polarizing filter due ...)
The sun visor liked better the old lens, by the length of the front lens was better protected.
In summary: excellent, clear picture quality with gebsserte almost unpleasant sharpness, a high-quality plastic frame that is lighter and shorter than its predecessor.
Expensive, very expensive, but also an excellent lens.
For me, despite the price 5 Stars.
