[FUJIFILM X] This was one of the first lenses I bought for my GH4 and it's been one of my most used. Renders beautiful colors and flares (if you're into that sort of thing), is wonderfully sharp even wide open, and has a very responsive and smooth focus ring. It's a beast in low light, which makes it especially useful for Micro Four Thirds shooters. A really nice normal prime focal length, especially when paired with the GH4, as this lens comes out to about a 48mm full frame equivalent with the 4K crop. So if you're coming from full frame system with classic 50mm f/1.8 setup, you'll feel right at home with this lens. The body is a metal frame with a tough plastic exterior. It feels well built and and sturdy, and it's stood up marvelously to about a year's worth of consistent use. The construction on all the Rokinon lenses I own has been solid, and I definitely find it better than the all-plastic builds of the budget Panasonic and Olympus lenses. The only real downside some may find with this lens is that it's fully manual. If you are predominantly a video shooter like me, this probably isn't a huge loss, but some photographers may find it unideal. In addition to being fully manual, the focus ring also does not hard stop at infinity, going a few degrees beyond it. So that's important to keep that in mind if you want to use this lens for landscape or astrophotography work. This issue is pretty common on lenses in this price range, and I still prefer a manual ring to wire focus when it comes to trying to nail focus on distant objects. Whether you're a photographer or videographer, this lens has a lot to offer, and for the price it's tough to beat.

[T22] In over 40 years of industrial and feature film making, the Irix primes are my favorite series of prime lenses, favored over the big name lenses that cost 4-5x. They are fast, sharp, have very natural-looking out-of-focus highlights, and the sealing is a bonus for those like us, who shoot a lot of exteriors. Hopefully Irix will soon offer something in the 65mm-85mm range so we can relegate our current short telephoto to the B camera lens set.

[T22] I purchased this lens for my sony FX9 and I shoot with the raw extension. I mostly use the 28/135 F4 sony cine zoom lens. I needed something a bit more wide with a fastest aperture. My dream came true. this lens is excellent, extremely sharp and delivered stunning results. I have tried also the sony 16/35 GM master f2.8.. . but sometimes a real cine lens is better when autofocus(es) has their limitations and when manual focus is required for creativity. highly recommended

[FUJIFILM X] bought this under a slew of positive reviews, i love the focal length in my sony e mount cameras apsC sensor. I have nothing but positives to say about this lens. Clarity, nearly perfect even for pixel peepers. Very nice bokeh at f1.4 easy lens to use more often than not. aperture and focus smooth. Its my second of 4 rokinon/samyang lenses and they are all first rate in quality both build and image. If you can live without AF and this is a focal length you like i cant think of a better choice.

[58 mm] I received the lens on estimated arrival time and the lens look good and work perfectly. I love to buy more with B&H because I feel safer with the quality and guarantee. Thank B&H.

[FUJIFILM X] I have owned this lens for about 6 months now. I absolutely love it for video on my xt3 as it produces images with a special cinematic quality. Smooth as butter focus and aperture rings, solid build quality. Very little to no distortion for a 21mm. Decent bokeh for a WA lens, and very fast for the price, also sharp in the centre wide open. I highly recommend it and am surprised more Fuji shooters don't seem to know about this hidden gem of a lens.

[1.1 lb] This lens is truly a gem. Superb craftsmanship, sharpness and color rendition., it's a wide angle lens with very little distortion. Pulling focus is a breeze with this lens. With added accessories it has turned my BGH1 into a full-fledged cinema rig.

[T22] This lens is sharp and has very nice/strong bokeh wide open. It is also compact and perfect on the a6000. Very solid construction and has a smooth focus ring with much better feel than the focus-by-wire sony lenses. Paired with the mirrorless manual focus aids like the zooming and peaking (you'll need to map a button to do the focus zoom because it won't be able to sense that you've started zooming) this lens is great for street photography. This is a lot of lens for the money.

[T1.5] Loving this lens, small, compact, well made. Focus and aperture rings are nice and smooth, optics are sharp. Works perfectly on the X-T3

[1.1 lb] Purchased this lenses at B&H for my Sony A6000. Keep in mind -this a fully MANUAL lense - No complaining please. Construction - Excellent, a little too well-built for the A6000. For it's size, it's heavy. Mount fits snugly, will notice minimal shifting when jerking the camera, but it's expected - weighs more than the camera. Lens cap good; Mount cap garbage. A true wide angle. Very easy to get the whole frame in focus and sweet subjects isolated when needed. Focus ring is great - for my liking. Aperture is clicked. Center starts sharpening best at F2.0 Corners Best from F4-F8. Better Contrast than the Sony 50mm 1.8, 55mm-210mm, Sigma 19MM, 30MM, 60MM, Can sometimes can be sharper than all of the above. If you really want a quality FULLY MANUAL wide angle lens, then buy it. Otherwise, Touit, Rokinon 12MM F2 (ULTRAWIDE). WARNING: A. Bad lense shadowing when using on-board flash on the SONY A6000. B. Will have to set a custom key to use Focus Magnification. (I used the center dial key - lost Eye AF) Will not automatically pull up this feature like other supported Sony lenses. C. Goodbye Quick Hybrid AF features.
