[f/1.2] I use this lens with a Sony alpha 6000. The Lens is incredibly sharp, with little to no barrel distortion or chromatic aberrations. It is a prime lens, and it does not connect electronically to the camera -- this means manual focus only and no EXIF information stored on the shots as to the lens and aperture used. If this is OK with you (it is with me), then this is a great lens. I now use only Rokinon / Samyang prime lenses in addition to the 55-210mm Sony zoom lens for wildlife shots with the a6000. Some people have noted that there should be a distance scale to help with estimating the deapth of field, but after having had the lens for a while you will develop a good intuition for this anyway. One thing that could be an issue some months / heavy usage down the line: f numbers and focusing distances are painted not etched into the lens, so they could wear off after a while I guess.

[Manual Focus] I purchased this Lens so that I could use it for wide field Nebula shots. It has delivered in all aspects. I will be using it with a Monochrome camera next.

[9, Rounded] i had this one for a month barrowed from a friend  but man I compare it.Yes it sharper than xf 56 . but 56 has the magic ( blur)

[f/1.2] I've owned the 56mm f1.2 before and this lens was clearly made to be a much cheaper alternative to that lens. Some comments based on categories:�
- Cost: Got it on a holiday sale for $380. The Fuji 56 used is around $750. That's almost half. I could buy another lens with that money. And I did.�
- Focusing: Manual focusing with focus peaking and focus checking I've found is so much more accurate, reliable, and enjoyable than autofocus in portraiture.
- Weight: Almost 1/3 lb lighter than the Fuji 56. I mean...why bother going mirrorless if you prefer more heft.�
- Build: Mount is metal, which for me is all that matters. I like that the barrel is plastic rather than metal because for one, it's much lighter, and two, I don't feel like I have to baby it as much. Plus this is clearly a portrait lens...why would I need for it to be able to withstand getting dropped when I'm standing still? Just don't drop it...
- IQ: Sharpness is dumb at 1.2. Dumb good. I've never NOT had to apply sharpening in post. It's that sharp.

If you're wondering why you have to pay such a premium for excellent optics for Fujifilm cameras, you don't. Try Rokinon. You won't regret it.

[f/16] I've seen a review of this lens that states it's sharper than Fujifilms own 56mm f/1.2...I don't know for sure but this is a very nice sharp lens (as they say, for the money)....or for any amount of money..Try it, if your not happy with it just send it back..

[f/1.2] Great lens. Really nice images even wide open. Build feels good, focus and aperture rings are smooth, well damped, and don't have excessive play.

[Manual Focus] I bought this along with the Sigma dc dn art 30mm 1.4 for my a6300. Optics wise I would choose this over the Sigma. The Rokinon is heavier with a plastic body and yet still nice feeling .There is little purple fringing wide open on high contrast scenes and it is completely gone between f2-2.8. The sharpness and contrast throughout is fantastic. I was surprised how well it did at 1.2. There is no noticeable distortion. The colors are great. The bokeh is very smooth. One of my favorite lenses I have ever owned. I plan I using this for Product shots, video and portraits. Remember if you buy this it is for apsc not full frame. Also manual focus only, which is very smooth. I would 100% recommend this lens. I posted a photo I took with it!!!

[62 mm (Front)] Solid build quality and sharp details are just about a portion of what I could say. I love it!
Don’t buy it if you are after a light and compact 50mm. This is a huge beast.

[Manual Focus] Images from this lens look outstanding. The sharpness wide open is very respectable, and you be hard-pressed to complain about it from f/2.8f/8. There is some color fringing in high contrast areas, but still very well controlled. Shooting plenty of video, I have noticed that there is slight focus breathing on the lens, but its only apparent if you rack focus from infinity to a close subject quickly vice versa. Build quality is solid. Using the focus/ aperture rings are a pleasure and I'm a huge fan of the look of that metallic red ring :P infinity focus is not at the hard stop but thats not an issue for me. The lens fits snuggly on my a6500. The only complaint would be that the lens hood and rear lens cap are pretty loose.
