Thank you, It's a good lens. But this is a crop. For full-frame, Sony ar7ii you can use, but on 16 mm you see a crop when you change mode 35mm, you don't see a crop, but you see about ~20-35mm.

Fit and finish are very good. The lens appears to be clad in metal, and has a metal mount, but is extremely light-weight and almost seems like it could be a mock-up, with no glass or internals. At first I was hesitant because of some reviews that i had read online about its poor IQ overall.

Got this lens to use on a gimbal. It's smaller than the kit lens with a wider aperture.

Good Points: Excellent quality - good combination of automatic features - easy to use menus Bad Points: Yet to find any

I bought this lens for wide angle indoor an architectural shots and also as a platform for fisheye and ultra wide convertors from sony. The image quality is just fine. Considering the price its better than that. The colors are crisp and clean, with good contrast.

Very very light weight; good image quality for the price; fast accurat focus and makes your nex camera truly pocketable

Corner sharpness

high quality lens that complements the Sony Nex package. Was part of the Sony promotion.

Easy To Use; Great Addition To Package; Quality Construction; Lightweight

Decent lens for the price. Together with the ultra-wide and fisheye converters, this a great deal but image quality is average at best. Videographers can get away with the quality although there's no hybrid AF (contrast+phase detection) support so AF is a little slow (at least it's smooth).

"It is not comparable to those $1K+ prime lenses, but it is good enough for overall shooting. If the goal is to go up one full F stop for better low light performance than the 16-50mm F3.5-56 kit lens offers, this is the cheapest way I know, to achieve it.

It came with Nex kit.. and it is sharp centrally. It is light weight with full metal build.

Price; size; central sharpness

Uniformity of sharpness

The AF performance is pretty good for a contrast detection system (albeit highly dependent on the base camera). AF operations are basically noiseless. Manual focusing works "by wire" so the focus ring is not directly coupled to the focus gears but to the AF motor.
