The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 12mm f1.4 and the Venus 12mm f2.8 MF for their suitability to various photography scenarios:

Besides being longer, the Venus 12mm f2.8 MF also has a larger diameter of 77mm compared to the Sigma 12mm f1.4's 69mm diameter.
