Review on Rokinon 12mm F2.0 NCS CS Ultra Wide Angle Lens 📷 Sony E-Mount (NEX) - Black (RK12M-E) | Enhanced Photography & Videography Tool by Viswanath Lopez

Build Quality: The lens is well built and relatively small. The mount is metal and the front of the tube and focus ring are plastic. Has a 67 mm filter thread; my UV filter fits well and looks good. The aperture ring is a bit small, but gives a nice click when adjusted about half a step. The aperture and focus rings are well dampened and require both fingers to turn. Close focus is a little less than 0.66m and focuses a little further than infinity, but there is an infinity marker. The lens hood is a bit cheap and also has a little play when installed. Overall, the build quality is good and can withstand rough use. Performance: The lens performed very well for my use. I will only take landscapes and night shots with this lens. The center is sharp at f/2.0 with a peak around f/5.6. The corners are a bit soft wide open but sharpen sharply at f/4.0. When focusing on the stars at infinity, the corners opened surprisingly well. The coma was also well controlled. It can be exposed for up to 25 seconds without leaving any star trails. There are few distortions and there should be no problem correcting them in post. It has strong vignetting at f/2.0 but improves at f/2.8. Overall, it has excellent performance for a $400 lens. Other thoughts: I set the C2 button on my A6000 to zoom so focusing is easy. It looks well balanced and is only slightly heavier than the Sony E 50mm f/1.8. This lens is very aesthetic and looks even better on a black camera. Update March 2016: I mainly use it for seascapes and nighttime lapses. He has been crushed by sea waves many times and is still going strong. Compared to other wide-angle lenses, this one is very small and light. Ideal for hiking if you want to take as little gear as possible. I use a 3-stop Tiffen ND filter for waterfalls and the sea.
