I’ve been impressed with the growing range of Viltrox Air lenses for both APS-C format and full-frame cameras. The former includes the Viltrox AF 15mm f/1.7 Air, Viltrox AF 25mm f/1.7 Air, Viltrox AF 35mm f/1.7 Air and Viltrox AF 56mm f/1.7 Air. Full-frame contenders include the Viltrox AF 20mm f/2.8 Air, Viltrox AF 40mm f/2.5 Air and Viltrox AF 50mm f/2 Air. I’m also keen that, especially in the APS-C camp, the lenses have such a unified design, all sharing the same aperture rating and handling characteristics, and all being virtually the same size and weight.
The newest pair of Air lenses are ultra-wide-angle primes for APS-C and full-frame cameras respectively, this APS-C format AF 9mm f/2.8 Air again being a very similar size and weight to others in the range but having a narrower aperture to enable the same level of compact and lightweight build. And let’s face it, f/2.8 is pretty fast for such an ultra-wide-angle lens.
