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 Venus 15mm f4.5 for their suitability to various photography scenarios:
Size and Weight Comparison

On the other hand, the Venus 15mm f4.5 has a larger diameter of 70mm compared to the Viltrox 14mm F4.0's 65mm diameter.
