The affordable Samyang 16mm F2.0 ED AS UMC CS is a sharp, fast wide-angle lens for APS-C SLRs and mirrorless cameras.

    Nice price. Quite sharp. Focuses to 7.9 inches. Available for multiple systems.

  • -

    Doesn't cover a full-frame image sensor. Manual focus isn't for everyone. Omits optical stabilization. Some fall-off at corners.

This lens is sharp with low coma for night photos.It takes a little bit to get used to the manual focus but once you do its fast and sharp.It is better than the 14mm and other lens that cost more.

I bought this lens to enable better night and astro photography. I needed a faster wide-angle lens and I am not disappointed. But you must do a lens test before going out into the dark. The focus wheel is not calibrated very accurately, but that doesn't mean you can't find the sweet spot.

Absolutely fantastic lens. Ok, so it's not thousands of dollars and honestly if your a professional, my opinion may seem uneducated and uninformed. However, I'm not going to drop thousands into a lens and this lens preforms spectacularly on my Samsung NX500, as well it outperformed other lens...
