Excerpt: great lens! super large aperture catches low light and gives a great shallow DOF. small enough to "live" on the nx300: the whole package is practically the size of a point and shoot. Amazing results from this lens, rivaling the top of the line nikon and cannon lenses. I would recommend to anyone to buy as a standard kit item when purchasing the nx300.
Pros: Durable, Easily Interchangeable, Fast / accurate auto-focus, Great in Low Light, Lightweight, Rugged, Small, Strong Construction, Well Conceived
Excerpt: All the benefits of a 30mm zoom without the drawbacks of a higher f-stop. I've had great success using this for portrait shots for 3 reasons. 1) 30mm zoom allows for a close cropped shot without getting into someone's face 2) 2.0 f-stop achieves a very shallow depth of field which I love. The low baseline also helps in low light situations 3) The smaller lens is less intimidating to your subjects allowing them to be more comfortable.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight
