Excerpt: I bought this for my A7 to use as a walk around/travel lens. It's a compact and has a nice quality to it. Only thing that would make this lens better is if it were black and matched the finish of the A7.
Pros: Easy To Use, Lightweight, Quality Construction
Summary: Some people complain about this lens because it is not a pro lens. It does a good job for the price, just don't expect it to be the same as a $1,000 lens. I paired it with a wide angle converter lens to give me two options. On its own, it is relatively short.
Great for wider view. Severe stretching at edges. Fun lens to use.

Summary: This lens is great IF you have the 16mm and it will get you to 12mm. If you have the 20mm it will also work, but will get you to 16mm, which begs the question why you would not use or get the 16mm in the first place.
Excerpt: This is great if you're looking for the lightest weight option. Photos are just like others have said, best if you stop the lens down to f8 or so. Although using it wide open for most people is fine. I use this lens mainly with the wide converter, which adds size and weight.
Summary: This lens by itself doesn't really produce shots that are any wider than when using the kit lens (16-50mm). But it does really decrease the size of the camera when it's on, and when combined with the VCL-ECU1 ultra-wide converter, the results are great.
Excerpt: It's so light that you just must have it. I love taking photos wherever I go and hate carrying heavy things with me. I have a NEX3F which is really light already, but with this lenses, it's even lighter. Amazing!
Pros: Easy To Use, Improves Performance, Lightweight
