In reply to Okiedrifter • Mar 23, 2015 Finally blessed with a clear night so I tried out the 24mm. The Canon EF-s 24mm f/2.8 STM is a tiny and super-sharp normal to wide lens for Canon's APS-C cameras. It makes an excellent replacement for any 18-55mm zoom, saving size and weight and adding a fast f/2.8 speed for use in dim light and making your viewfinder brighter. Canon EF-S 24mm f/2.8 STM – Build and handling In keeping with its predecessors, the EF 50mm f/1.8 STM is a small and lightweight lens, weighing 30g more than the EF 50mm f/1.8 II. If you're wanting this specifically for astro, I would say that instead, take a look at the Samyang 24mm F1.4 manual lens. It has excellent coma handling compared to Canon equivalents. Stop down to F2 for sharpness. Still a very fast lens. Just search for comparison reviews of that lens vs a Canon lens and see the examples. vKxsmRt.
