The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Viltrox 14mm F4.0 and the Sony E 10-18mm F4 OSS 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. Sony E 10-18mm F4 OSS is the longer of the two lenses at 64mm. The Viltrox 14mm F4.0 with a length of 56mm, is 8mm shorter. Besides being longer, the Sony E 10-18mm F4 OSS also has a larger diameter of 70mm compared to the Viltrox 14mm F4.0's 65mm 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 14mm F4.0 weighs 170g, which means it is 55g (24%) lighter than the Sony E 10-18mm F4 OSS which has a weight of 225g.
Lens Mounts
Both the Viltrox 14mm F4.0 and the Sony E 10-18mm F4 OSS has the same Sony E lens mount. Some of the latest released cameras that are compatible with the Sony E lenses are Sony FX5, Sony A7R VI and Sony A7 V.

Viltrox 14mm F4.0 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.
On the other hand, the Sony E 10-18mm F4 OSS has a focal range of 10-18mm and 1.8X zoom ratio which has an effective (full-frame 35mm equivalent) focal range of 15-27mm when used on a APS-C / DX format camera.
