I use this on my canon 70d for landscape and night pictures and I am very happy with the purchase of this lens. Landscape pictures come out beautiful but this lens shines when used for night & astrophotography! Well worth the investment!

Brilliant lens. The only drawback is that there is no communication with the camera for F numbers used, all you get in the exif and on the display screen is F00 which is fine for me but others should be aware of this.

Gary Wolstenholme reviews the Samyang 16mm f/2.0 ED AS UMC CS lens.

Very good value for money; Excellent sharpness in the centre from maximum aperture; Good build; Very good sharpness towards the edges stopped down to f/4 or beyond

No hyperfocal scale; Petal shaped hood is a little loose

The Samyang 16mm F2.0 ED AS UMC CS is a fast manual focus wide-angle prime made by the Korean lens manufacturer Samyang. You might also find identical clones of this lens sold under the Rokinon or Bower brand names, among others, depending on where you live.

Fast F2.0 aperture; Pleasant bokeh; Exceedingly sharp across the frame; Minimal barrel distortion; Great contrast; Ghosting and flare resistance; Great starbursts in daylight; Aperture ring control and automatic aperture control (supports M; A/Av; S/Tv; and P; Affordable at $479 or less

Difficult to fine focus in viewfinder due to wide-angle and large depth of field, Prominent vignetting up to F2.8, Sub-optimal flare control in harsh light, No in-camera lens correction profile, Swirl bokeh when used wide open, 1 year U.S; warranty

This is a great bang for the buck lens. Great performance and the best part is it is rectilinear and not fisheye.

The 16mm F2.0 ED AS UMC CS ($499) is just one in Samyang's line of affordably priced manual focus lenses for SLRs and mirorless cameras . It covers a very wide field of view, and opens up all the way to f/2 for low-light photography.

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

Manual focus only. Quality of pictures is poor.

Handling and features This manual focus wide angle lens for APS-C format cameras, offers a fast f/2 maximum aperture for a budget launch price of around ￡419.

Perfect Lens for Video !

Very sharp; good Angle; PERFECT Value for Money!!

No

The Samyang hit the market as the overall widest aperture 16mm lens, but Tokina later dampened this claim with the release of their 14-20mm zoom lens also providing the same f/2 max aperture.
