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.

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.

I have had the lens for about 3 years. When I first got it, the lens was okay. Not perfect by any means but it was small and a bit faster than the kit lens at 16mm. Trouble is the lens started to die a few months after the warranty expired.

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

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).

Well, there's a reason lenses are expensive and you get what you pay for. The main draw for this lens is the size and weight. Build quality's good, too. Thin aluminium and smooth focus ring. It's incredibly convenient and if you're a casual photographer who's put off by heavy equipment, a good buy.

I bought to use on a Sony a6500 along with a Sony E 35mm F/1.8 Oss lens. This lens is way too soft in the images and video. Compared to the 35mm, it's not even close. The 35mm is razor sharp for pictures & video with very quick focus. The 16mm will most likely be my first B&H return.

"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.

This light weight short focal length lens is a must for the NEX-5 camera and the ultra wide adapter lens VCL-ECU1 as well as the Fish eye converter VCL-ECF1 makes this combination a "must have" to complement the other NEX lenses.

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