Summary: This was my first Carl zeiss lens and it is worth every penny I paid for. It delivery very sharp images from wide angle 24 to 70mm. Its super sonic wave motor is something else. Fast and quite. Highly recommended.
Summary: Yes, it's big and heavy. Yes, it's expensive. But you don't get first quality glass without making a sacrifice. I've used Zeiss lenses for over 40 years and this one hold up well against any of them. This is my normal working lens. It's as good as any top lens from any manufacturer.
Summary: Just fantastic, this lens is extremely impressive. When used with an a65, a77 this lens is king. If you are a pro looking for a good mid zoom lens this is it. I wouldn't recommend it for portrait shots but it is pretty versatile. This is a great choice for a rental lens because it is a little expensive for most of us to buy. renting it is probably a good choice if you know what period of time you might use the lens for.
Pros: fast 2.8f, fast autofocus for the glass, smooth manual focus ring, large front glass, 72mm filter size, looks good
Summary: I took the plunge with Sony and the A850 & A900 bodies in 2009/10 after decades with Nikon (D2x). As a full-time pro, with 4 kids and being a single income family the D3x was out of my range (due to the financial crash) and I needed 25mp fast for a ongoing print retail project. This lens, with the A850 and A900 bodies, has fed my family for the past 3+ years without a hiccup. I shoot for mid-level ad agencies and travel North America.
Pros: Very tough, sharp, good contrast, good CA control
Summary: This is the finest AF zoom lens that I've ever owned. It's heavy, but I use it as my primary lens due to the versatility and quality. I would purchase it again without hesitation. You won't be sorry if you buy this, except if you're climbing Mount Everest and need to carry as light a pack as possible! This lens is heavy!
Pros: Excellent workmanship, speed, and performance
Summary: The images you get from this lens are amazing! The lens performs better than expected. Color and sharpness are beautiful. Buttery smooth bokeh. Great build construction. (I would not call the weight of this lens a Con. Good glass is heavy. If you want this level of quality, the glass is going to be heavy.
Summary: I have used this lens for over five months and it rarely leaves my camera. This is a great lens to walk around and take your picture perfect photo. Although this is a zoom lens, the quality of photos is breath taking. The only down side to this lens is the weight; however, the weight is worth the pictures that it takes. The lens is great at taken pictures at night and indoors. I have many friends and family members that choose the pictures I take with this lens to print.
Summary: I bought this lens as an upgrade from the SAL-1680Z, which I gave to my wife. Compared to the 16-80, this lens is slightly sharper, with slightly better color, slightly better flare control, no vignetting, and no distortion (although it's not as wide as the other Zeiss' 16mm). The SSM focus is faster and quieter, and the build quality is better overall. How do I know this?
Pros: Sharp, rich colors, nice bokeh, tight build, good low-light performance, fast and silent focus
