What excites me about the lens: It is absolutely sharp, if it is properly focused. Even in Aperture 2.0 is well used to beat from Aperture 4.0 barely.
The Bokeh is beautifully soft and you can freely post items outstanding.
The CAs are hardly noticeable and even without sun visor I have hardly found reflexes.
The Innefokusierung is very pleasant and the macro range excellent.
Visually therefore a real highlight !! Here I would give full marks.
* For me unacceptable: The focus, both manual and auto ~.
- First, to autofocus. In my test shots, he was more than half of all shots next. For example, when I Focused on the eye, was once the ear, sometimes the chin or neck "knackescharf" but the eye itself at most in 30% of cases. (Diagonally positioned to the image plane) Even with a ruler, photographed with a tripod, the sharp area was usually much beside the point focused (spot focus setting). At almost the same shooting situation, I received significantly different results.
Also, the speed of AF in many standard situations (eg portrait, nature, architecture ...) absolutely unacceptable. Even my cheap lens "Tamron AF 18-200mm" is always much faster. The "Tamron SP AF 60mm F / 2.0 Di II Macro" sometimes takes 5 seconds or more until it focused. And then there is often still focused wrong. In part, it also pumps back and forth and found absolutely no focus point.
- The manual focus should really make a AF OK signaling in the viewfinder or display when was focused properly. But He does not always, and if they do, it is often wrong.
Since neither of the opt. Selectors of A550 is still focusing owned the display to 100%, I have "MF CHECK LV" used with zoom function to focus properly - then the photos were also absolutely top.
As I mentioned above Manual Focus on duration is much too complicated, I'll send back the lens and order on the occasion of another copy - in the hope that I caught with the current one "Monday Model".
Just a note for manual focusing: The adjustment affects unfortunately with a slight slip of about 5 ° to the optical system. So you have the back and forth a little game before the focus changes.
. So visually 5 points, focus 0 pts -> usefulness for me 2 pts
