Summary: It's an okay pancake lens. The size is really the best part about it. For the money you can buy better lenses, in that size or other sizes. Really soft wide open. Stopped down to F4 it's significantly sharper, but you by an F2.8 lens to be able to shoot that fast. I recommend the Sigma 30mm (which is cheaper) or the Sony 35mm which runs about the same price.
A significant improvement over the older 16mm ƒ/2.8

Summary: As far as fixed, pancake, wide-angle lenses go, this one is pretty spectacular. I used own a Sony NEX-5 with the 16mm ƒ/2.8 and it was fun, but was super soft and had tons of edge distortion. When I decided to buy a Sony A-6000 I decided to pick this lens up to go with it and WOW! It's a remarkable improvement over the older 16mm but in a similar form factor. If you're looking for a travel landscape lens this is the one.
BEWARE IF YOU WANT TO USE THIS LENS WITH THE NEW SONY ALPHA 7II...MODEL ILCE-7M2

Summary: Incompatible with Sony's new and highly raved about Alpha 7II...just go to this web site and have a look...http://support.d-imaging.sony.co.jp/www/cscs/lens_body/index.php?area=us&lang=en&mdl=ILCE7M2...absolutely incredible that this is a suggested lens for that camera...Sony states on the site: "The angle of view will be narrower down to that of APS-C size."...and that goes for just about every lens listed on it's site..
Sharp, Very sleek design, and excellent build quality!

Summary: As of right now, this is my favorite walk around lens on my A6000. I mainly purchased this lens because I bought the body-only, and thought this would be a great lens to have. I was right, and find myself using it a lot of the time. It truly looks sleek on my camera and without the lens hood on, it becomes very compact. I would imagine on an NEX 5t or a5100 it would make the camera very pocketable.
