Introduction
On the same day that Viltrox introduced the AF 14mm f/4, an affordable autofocus ultra-wide-angle lens for full-frame cameras, they also announced a 9mm f/2.8 autofocus lens for APS-C cameras — the widest AF prime lens for crop sensors and another addition to their compact, lightweight Air series.
I tested this lens on a Nikon Zfc via a Megadap adapter (Sample images were taken with a Sony a6700)
