The Sigma 14mm f1. 8 DG HSM Art lens is the fastest aperture wide angle lens that you can currently find on the market, and it's perfect in so many ways for the photographers that do astrophotography as well as those who photograph interiors in low lighting.

It's very difficult to do despite many lens options on the market finding ways to make this easier. At the same time, photographers can argue about how modern day sensors are so good at getting the image that you may not need those filters.
