Nikon introduced the AF-S Nikkor 16-35mm F4G ED VR back in 2010, as an alternative wide angle lens for users who want a professional quality lens without the weight and price of F2.8 glass. While the AF-S 14-24mm F2.8G and AF-S 17-35mm F2.8D IF are great lenses, they are both heavy and expensive. While the 16-35mm F4G VR still would not be considered cheap, it does come in at a lower price point than the current F2.8 wide angle Nikkors. In addition, the 16-35mm F4 has a feature the that none of the other wide angle Nikkors have, vibration reduction (VR). While VR might not seem like an exciting feature for a wide angle lens, in the real world it can be extremely useful for landscape or architecture photographers who don't always want to lug around a tripod.
The AF-S 16-35mm F4G VR has received mixed reviews, some praising and some bashing the lens, from professional reviewers and users alike. From the get go I want to point out, that I think the lens performs extremely well for the price. I am not going to dive into things like resolution charts or anything like that, those do not mean much to me, so I wont use that to measure the lenses quality. If you are looking for a technical review of the lens, I recommend checking out the review on Photography Life.
The zoom ring on the lens turns smoothly throughout the zoom range. Note that the front element of the lens extends and retracts while zooming. The manual focus rings on the lens feel well dampened, and manual focus is reasonably easy to achieve, for a modern auto focus lens. There are rubber grips over both of these rings. The included lens hood (HB-23), which also ships with several other wide angle Nikkors, firmly snaps into place via a bayonet mount, and it seems unlikely that it would fall off. The lens features a 77mm filter thread, making it ideal to use along with other professional glass.
