Awesome astro lenses: Comparing the Sigma 14mm f/1.8 against Rokinon lenses for night sky photography

When shooting star photos, there are multiple aspects of a lens to consider. Primarily, you typically want a wide-angle lens. Not only does the lens need to be wide, it also needs to be fast. A lens like the new Sigma 14mm f/1.8 lens stands out as a good choice, for example, and Rokinon makes numerous fast wide lenses. The Rokinon (and Samyang) lenses are manual focus, which makes them less useful for some types of photography, but that does not matter for shooting the night sky as you would never want to use autofocus in that situation.
Photographer Matthew Saville has created a new video for NatureTTL in which he considers the best lens for star photos. He compares the new Sigma 14mm f/1.8 Art lens with Rokinon's 14mm f/2.4 and f/2.8 optics by looking at factors such as vignette, distortion, sharpness and more.
