The Rokinon Reflex 300mm f/6.3 ED UMC CS Lens (Black) is a mirror lens designed specifically for use on Canon EOS M mirrorless cameras. The lens' Cassegrain design enables it to achieve a 480mm 35mm-equivalent focal length perspective within a compact and lightweight lens design that is significantly smaller than a traditional 300mm lens. It features a fixed f/6.3 aperture and utilizes manual focus operation for focusing as closely as 2.95'.  One extra-low dispersion element and the inherent mirror construction of the lens work to eliminate chromatic aberrations while providing notable image sharpness and clarity. Furthermore, the UMC (Ultra Multi Coated) coating has been applied to reduce surface reflections, lens flare and ghosting while also contributing to improved overall contrast.

Given this is a manual lens, focal depth is extremely important.  Unfortunately, when taking pictures of deer standing within 3 feet of one another, one was in focus and the other out of focus.  When attempting astro photos from a tripod, I could not get the moon or stars to properly focus either.

Razor thin focus

as stated in the title this lens represented a point on the compromise curve: very low cost, good physical construction, mediocre image quality. When shooting against any light background the vignetting is strong enough to make post processing a hassle. Sharpness in the dead center is also visibly worse than premium super telephoto lens. The other problem is the sheer difficulty of getting a good focus. I was trying to put it on infinity when shooting the moon, and it felt like that the focus ring needs to be placed with very high precision. I needed to do a 'focus bracketing'. Because of the low cost, I have to give this 4 stars rather a lower score reflecting its image quality. before you buy, check out all the reviews on the internet and think about your priority.
