The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Viltrox AF 16mm f1.8 L and the Samyang MF 14mm F2.8 Z for their suitability to various photography scenarios:
Size and Weight Comparison
The size of a lens is a crucial factor to consider when comparing two lenses. Samyang MF 14mm F2.8 Z is the longer of the two lenses at 124mm. The Viltrox AF 16mm f1.8 L with a length of 103mm, is 21mm shorter. Besides being longer, the Samyang MF 14mm F2.8 Z also has a larger diameter of 87mm compared to the Viltrox AF 16mm f1.8 L's 85mm diameter.
The weight of a lens is equally significant as its external dimensions, particularly if you intend to handhold your camera and lens combination for extended periods. Viltrox AF 16mm f1.8 L weighs 550g, which means it is 260g (32%) lighter than the Samyang MF 14mm F2.8 Z which has a weight of 810g.
Lens Mounts
The Viltrox AF 16mm f1.8 L has the Leica L lens mount whereas the Samyang MF 14mm F2.8 Z has the Nikon Z lens mount.

Viltrox AF 16mm f1.8 L is a prime lens with fixed focal lenght of 16mm.
On the other hand, the Samyang MF 14mm F2.8 Z is a prime lens with fixed focal lenght of 14mm. When it is mounted on an APS-C sensor camera with 1.5x crop, it provides a 35mm (FF) equivalent of 21mm.
