Review VerdictThe Viltrox AF 15mm f/1.7 Air XF is another welcome addition to their ever-increasing prime lens lineup. At least on 26-megapixel sensors, the sharpness is fine from f/1.7 and great from f/2.8. At f/1.7. Image distortions are on a low level, albeit a bit wavy. The vignetting is a bit on the high side, which doesn't come as a surprise given the compact size of the lens. Sun stars aren't a big strength, if that's your thing. The build quality follows the tradition of the other Viltrox Air lenses. The engineering plastics are of good quality, and everything is tightly assembled. While it doesn't have any kind of weather sealing, the internal focusing mechanism should provide at least a bit of protection against dust. The AF uses an older-style STM motor. However, it's still pretty fast and essentially silent. It may not be the most fancy lens around, but budget-oriented users may certainly appreciate a lens that is decent, surprisingly fast, and which still doesn't cost an arm and a leg If you'd like to support our work, please consider shopping for this or other lenses via one of the following partners: * Viltrox Store * Amazon (Europe) * B&H (US) * Adorama (US)
