Review VerdictViltrox continues to release quality lenses at prices that can't be matched by the traditional players - it's not even close. This also applies to the Viltrox AF 9mm f/2.8 Air XF. It's an amazingly sharp lens despite the extreme focal length. Some other players should be ashamed in comparison (I'm looking at you, Fujifilm ...). Lateral CAs are very low, and image distortions are quite easy to live with as well. If nice sun stars are your thing, the lens can do that for you. There's one obvious flaw, though - vignetting, but it's not a showstopper. In terms of build quality, the Viltrox lens is nothing special, neither in good nor bad terms. The plastic quality is quite decent, and the assembly quality is flawless. It's good consumer-grade quality. The AF is snappy. You can forgive the lack of weather sealing. Given the very low pricing, you may think of the Viltrox AF 9mm f/2.8 Air XF as a bottom feeder, but this doesn't do justice here because, at least in terms of sharpness, it is up there with the very best - and far better than most. So it's more than just a simple value recommendation here.
