Lately the Chinese Viltrox company has been showering us with launches of new lenses. In just 024 they managed to launch five models and in the first three quarters of 2025 they showed as many as nine instruments.
Among them you can find a very interesting Air series, consisting of small, lightweight primes (each construction weighs less than 200 grams), equipped with autofocus. Currently, they are offered as Fujifilm X, Nikon Z, and Sony E mount variant. What's more, producers decided to be competitive when it comes to aperture fastness and, despite a moderate weight and physical dimensions, they are able to offer an aperture as fast as f/1.7.
The portrait Viltrox AF 56 mm f/1.7 Air was presented as the first, in April 2024. In December the same year they showed a standard lens, the Viltrox AF 35 mm f/1.7 Air, and in 2025 there were two launches of wide angle models, namely the Viltrox AF 25 mm f/1.7 Air and the AF 15 mm f/1.7 Air. The following chart presents a comparison between basic parameters of these lenses.

It's also worth mentioning the fact that the Air series has been developed simultaneously in the full frame segment. So far, they have launched the 20, 45, and 50 mm models. As if it wasn't enough, on 19th September 2025 we saw a night launch of two really wide angle models. That day two Air lenses were showed – the full frame 4/14, and the 2.8/9, designed to cooperate with APS-C sensors.
Tests of these instruments we started from the newest, so the Viltrox AF 15 mm f/1.7 Air, then we decided to take a closer look at the 25 mm lens, and now we go back in time when it comes to date of launch and we are going to test the 35 mm instrument. It was made possible courtesy of the Fototechnika company that sent us one specimen of this instrument for testing purposes very quick and now we can present the results of our test in the following chapters – enjoy!
