The build quality is fairly similar to the Zeiss ZA 16-80mm f/3.5-4.5 DT (shown to the right in the product image gallery below) - it's decent but nothing to rave about either. The outer shell is made of good quality plastics. The broad, rubberized zoom ring operates smooth but also a little stiff.

Advertised as f/3.5 - 5.6. At 16 mm focal length, the maximum aperture is f/3.5. However, at 24 mm focal length, it jumps to f/4.5, and at 35 mm focal length, it jumps to f/5, which is disappointingly "slow", This information is not available in the "specifications".

Overall this lens is my favorite next to the 50mm f/1.4, I take this lens on all my shoots and have used in in most all weather conditions as well as indoor without flash. I find the versatility of this lens remarkable and really the best in class for the price.

A general purpose 6.5x zoom lens for APS-C sensor Sony and Minolta digital SLR cameras offering a wide-angle equivalent of a 24mm lens on a full-frame camera.

Useful zoom range; Good build quality; Good centre resolution at the shorter end of the zoom range

Resolution towards edges of the frame from 50mm onwards; Barrel distortion at 16mm; Prone to flare

I'm just getting used to this lens. I mount it on the sony a65. Previously I've had the 16-50 fixed f-stop. (which I Love) on my a65. The 16-105 is a fast focus and very sharp. It increases the range, and is a well-built lens. I will use it for landscape and possibly portraits.

Good general purpose zoom, nice and clear.

Consistent Output; Durable; Easily Interchangeable; Lightweight; Quick Focus; Sharp Focus

I thought the autofocus would work with my A7Rii camera with adaptor but I was wrong, I was reimbursed very quickly by them thanks.

I bought this lens to go with my Alpha 57, which was stolen, alas. I now use it with an Alpha 65. It gives good performance throughout the range and is good value money. It is an excellent replacement for the kit zoom, giving a step up in image quality. A bit heavy though.

Not many standard zooms extend to focal lengths in excess of 100mm, and the fact that this lens manages such a feat in a package that is no larger than Sony's companion 16-80mm ZA makes it worthy of serious attention.

Good short-end resolution from f/5.6

Poor resolution at longer focal lengths after f/11

Great lens!
