Combining a wide-angle perspective with a fast maximum aperture, this 21mm f/1.4 Lens from Rokinon is designed for Sony E mirrorless cameras and provides a 31.5mm equivalent focal length. One extra-low dispersion element and a trio of aspherical elements are incorporated into the lens construction, and help to control aberrations and distortions for increased clarity and sharpness. The bright f/1.4 maximum aperture excels in difficult lighting conditions and also enables greater control over focus placement, which is further complemented by the manual focus design and rounded nine-blade diaphragm to produce a quality of bokeh. Additionally, an Ultra Multi-Coating has also been applied to all lens elements to reduce lens flare and ghosting for increased contrast and color fidelity when working in harsh lighting conditions.

Rokinon 21mm f/1.4 Reviews
Defective mount ring
Optically the lens is quite good. But the mount ring is defective and the lens is not securely attached once placed on the camera. Unfortunately I noticed the problem past the return deadline. Sending it back to the US from Spain to be repaired is more expensive than buying a new lens. And in Spain, Samyang is not responsible for the warranty and does not have the spare part anyway.
Great lens for the M50
I’ve had this lens for a couple of weeks now, and it is my first new lens outside of the efm 50-200 and kit lens (15-45) I got it for it’s wide aperture capabilities, size, sharpness, and medium wide focal length. The lens is quite sharp and pretty easy to focus with focus peaking turned on, and the whole lens feels much, much higher quality than the kit lens, though it is quite a bit heavier so if you like to go backpacking like me, keep that in mind. The infinity marking seems to be correct on my lens, but it is frustrating that I can’t focus beyond infinity and come back to it to ensure that I’m at the perfect point for very distant objects. It appears to be only marginally sharper than my kit lens at infinity but has better colors and contrast. The lens appears to be sharpest at around f5.6 but is still quite sharp on closer subjects even wide open at f1.4. The amount of detail you get on close/medium distance objects is awesome, and the bokeh look great in my opinion. I went with the 21mm instead of something wider because I wanted a lens that was narrow enough to still take pictures of people, but was wide enough for landscapes and some astrophotography, a good compromise for backpacking trips. If you’re going for taking pictures of big Milky Way scenes, you’re probably better off with a wider lens, though this one still works fairly well in my opinion. Overall, this is a great lens as my first prime and I’ve really enjoyed using it the past couple of weeks for everything from pictures of people, landscapes, close ups of objects, and astrophotography. Having f1.4 is a huge step up from the kit lens.
