I am very pleased with the lens.

I tested this lens against the SEL-16F28 in the test setup with tripod.
Fundamental question which has been put to me, I sat in the future on a high-quality Zeiss zoom or fixed focal length lenses from Sony and Sigma.
The camera was always fixed on a tripod, as a photo opportunity served me a real wood cabinet with grain and a variety of everyday objects such as Wettersation, photos in picture frames, stuffed animals, etc.
All photos were shot with open aperture, ISO same values ​​and the same shutter speed.

The optical performance of this lens Zeiss is a Sony fixed focal lengths and Next to visibly superior.
Similarly, the colors are more intense and especially sehbar natural.
And the difference between open aperture 2.8 when compared to the 4.0 when Sony Zeiss was really not serious, so in terms of brightness.

So for me it was clear, if I 2-3 "favorable" fixed focal lengths and the "favorable" standard Zoom Sony buy me, or this one, as is the total price here is not really much difference. Vorallen as this objective is likely to be relatively stable in price.

But what I just miss in this price range, is a ausgewießene Adichtung against dust and moisture.
The easy part is when the price and I would have liked.

Otherwise, I would highly recommend this lens highly enough.

PS: And if you check it out on the bigger picture, what cost quality zoom in Canon, Nikon, Olympus, etc., then you realize pretty quickly that these are located in similar region in terms of price.
Yes, you have more open aperture, but the lenses are usually much larger.

Außnahme here makes Samsung with its new premium lenses, however, that trump the Zeiss priced still noticeable! Fuji is at full aperture and a little brighter, but the whole package even more expensive.

I am completely satisfied, use the lens with an Alpha 6000th
you get what you pay, and that's ok.
