Planning to shoot for some stars? Use this page to quickly find which of your lenses might capture the best results, in terms of their light capturing capabilities.
Is your 24mm f/2.8 going to capture brighter stars than 28mm f/1.8? Find out below. Also find the approximate maximum exposure you can use before the stars start trailing. Higher the Astro rating, better would be your chances of getting brighter stars!
The page calculates the ratings as described by Ian Norman. This is based on only the lens mm and f numbers, and does not consider the lens quality. For comparing lens quality check out the great resource at DxO Labs
