The Chinese company Viltrox recently has released several AF lenses in native Z mount. I got the AF 23mm f/1.4 STM ED IF (their designation, not mine) for the Z fc. This is a small, quite compact modern 11 elements in 10 groups design with ED and aspherical elements. Plus of course it has the electronics to allow the lens to communicate with the camera and conduct AF. It is made for the DX format.
Price was very reasonable and the lens shipped fast as well, apparently from a facility in the Netherlands. I got it this afternoon so just a few quick shots.The workmanship and build appear to be excellent and the lens itself delivered very sharp and contrasty images.
First example, of the fruiting rowan, is at f/1.4 and done in strong wind. I just pushed AF-ON and hoped for the best.
Second example is at f/5.6. NEFs are run through Photo Ninja with default settings.
I probably will open a dedicated thread for this lens, however it seems pertinent to sketch its potential here as it evidently is designed with Z fc (and similar cameras) in mind. The entry of new and competent lens makers is of course always welcome, no matter what camera their products target.
