[62 mm (Front)] 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.

[Manual Focus] I have both the Rokinon 35mm f/1.2 and the 50mm f/1.2 for my Canon M5. Both lenses are rockstars. While they require manual adjustment of the aperture and focus, I actually appreciate that level of engagement when shooting with prime lenses. This lens is usably sharp at f/1.2, much more so than the Canon 50mm f/1.2 (roughly the same focal length when mounted on their respective native cameras). The richness of the colors and contrast is on par with the EF-M 22mm, which is good. This lens also gets top marks for bokeh and build quality. If you're looking to add fast primes to your M kit and know how to shoot on manual with manual focus, this lens will deliver.

[APS-C] 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.

[Manual Focus] The Rokinon 50 1.2 surprised with top-notch performance wide open, little chromatic aberrations and no vignetting. It's the best performing 50mm I have used on the a6300 so far. If you can deal with the lack of AF go for it! Manuel focus feels smooth and built quality is excellent.

[31.7°] 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.

[APS-C] The Rokinon SP 1.2 series is honestly the most underrated glass I have used. This lens and the others in the series are some of the best full frame glass I have used. I can see why Samyang is now adapting them for the Meinster series. Though they should have picked a different name. I have used Zeiss, Sigma, and Canon L lenses of the same focal lengths. When it comes to sharpness and character these do a great job balancing it all.

[FUJIFILM X] I bought this lens with some experience using manual lenses before. Once mounted on my EOS M3, the lens feels solid and focusing was not a problem using the integrated magnifier and peaking focus option. The use of Canon EVF-DC1 viewfinder is also strong recommended. Lens focus ring is a little tought and it has a long travel from minimum distance to infinity, but enough to focus with precision. With that on mind, I purchased this lens only for adult portraits and pics of static objects. It's not suitable to shoot children or action photography. Prior to this lens, I had been using a Canon EF 50mm f/1.4 USM with EOS EF to EF-M adapter. The 50mm 1.4 was fine an easy to use but its image quality is average to my taste, specially with apertures below 2.8. This rokinon shines in IQ from f2. Sharpening and contrast are aceptable at wider apertures, and always better than the Canon and with smoother bokeh. Vignetting is also visible, but nothing to worry about it. Overall, is an excellent performing lens and optically superior to use than the Canon standard lens.

[f/1.2] 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)

[62 mm (Front)] This really is an amazing product. Extremely sharp, even wide open and capable of some really artistic shots. The sun stars it creates are beautiful and the light turns buttery soft as it's opened up. Astrophotography is crisp edge to edge at f1.2 with very little vignetting, coma, or astigmatism issues! Overall a stout performer regardless of your intentions. Be wary if you don't have a steady hand and watch your shutter speed to avoid shaky images since it doesn't have any stabilization. But, for the price and the speed it's worth the sacrafice.
