Compact Design
With its pancake design, the lens only extends 0.8" from the mount, resulting in a compact and lightweight camera system.
Portable design makes this a go-to lens for everyday carry and street shooting needs and the wide-angle field of view presents a natural perspective for a variety of shooting applications.
Bright f/2.8 maximum aperture suits working in available lighting and also contributes to the sleek size and lightweight design.
Optics and Focusing
Three aspherical elements are incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.
The lens uses a rear focusing design that contributes to faster autofocus performance as well as a minimum focus distance of 7.9".
Rounded seven-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.

Perfect One-Lens Solution

This is a great lens for travel, walk-about or street if one is looking for an ultra-light single lens solution. The lens is super lightweight, decently sharp and features a perfect (for me) focal length for general photography (I don't do video). Auto focus is accurate, however it's great just to set it to f8 and 3m focus distance and just snap pictures since everything from 1.5m to infinity will be reasonably sharp. I can't even tell I have a lens when it is attached to my A6700. If packing light is your priority nothing beats this lens.

Tiny lens that delivers. Took it as the only lens for our park days at Disney and it did fantastic.
