Not really good - certainly not for the price

I was looking for a good always-top lens for my A6000. On the A77 there is the 24-70 / 2.8 Zeiss: very expensive but the best money I've ever spent. The same should apply to the A6000. I had already bought the body with the excellent E-35 / 1.8 and now wanted a little more flexibility. The choice after a long search on the SEL-16-70 / 4 Z, because there are a lot of little else choice. The reviews are mixed: Reviewers do not find it so hot, private commentators love it. I realize that I seriously Level a zoom, the image quality of a fixed focal length and the much smaller, much lighter SEL-1670Z also can never keep up with the big SAL-2470Z. Should not there also. And I assumed that the reviews were based on the first batches that apparently had variations in quality. Unlike the difference between reviews and critiques not explained to me.

Said and done. The SEL-16-70 / 4 bought. It acts processed very valuable, is very small, fits comfortably in your hand ... and it was clearly a Dezentrierungsproblem: The entire left side was much less sharp than the right. This can be seen not only when photographing stone walls, but also in everyday photos. Well, it seems as if there are still quality problems since 1.5 years.

Lens exchanged, a new has arrived ... well ... it's still not centered clean. Slightly better than the first, but still a page is blurrier than the other. Overall, the definition is not good. And it's not bad, because the center is as sharp as some claim, but because the edges (or corners) just very, very bad look. And that does not go away even if you stop down. Well, one can cut away (the problem is that there is no alternative).

But in the more than one hundred test images that I have made, noticed that many photos not just came across the correct focus, which I'm accustomed. Sometimes you can see that the focus is just a few centimeters behind. Also on focused infinitely it is not really sharp. Not at all photos, but on very many (50/50 I would say). It is particularly problematic when the subject is in motion. Since the focus sits maybe 20% of the images.

I expect not at all that Zeiss can outwit physics and beloved 24-70 / 2.8 builds my in 1/3 the size and weight, and I will miss only slightly luminous intensity (by the way in retrospect not a good decision on my part, because a flexible always-plan should be flexible) and the light and depth of field. But here I get for 800, a lens with a clearly visible edge blur, focus and quality problems that already had 1.5 years time, the teething rid of them. On the plus side, however, is a small, well-made lens with a focal length suitable for everyday use and fair-weather light intensity.
