However, this can be almost perfectly corrected by turning on the default “Remove Chromatic Aberration” tool in Adobe Lightroom or Camera Raw, and fine-tuned using the manual “Defringe” sliders if necessary. Unfortunately, the Rokinon 12mm f/2 does suffer from some pretty wicked chromatic aberration in the corners, even when stopped down to f/5.6 or f/8. (Indeed, the “Cine” version of this same lens is, in fact, T2.2.) Color Fringing/Aberration In other words, you could consider the lens to actually be an f/2.2 or f/2.4 lens, as far as actual light transmission is concerned, instead of an f/2 lens. Rather, most of the image (everywhere except the dead-center) is not an entire EV brighter than f/2.8. The extreme corners don’t get too severely dark. Not bad, considering the focal length and aperture, but neither is it impressive. Your best bet is to use the lens profile that is available in Adobe Lightroom and Camera Raw (Bridge), which can correct distortion perfectly. However, it’s worth noting that the Rokinon 12mm f/2 has decently low distortion, but its distortion has a “mustache” shape, so it’s not easy to correct manually. I’m not shooting real estate interiors or too many scenes with lots of perfectly straight lines. I usually never worry about distortion, because it can be easily corrected with a lens profile (for still photos, not so much for video). Surprisingly, not only is the Rokinon 12mm f/2 impressively sharp, even wide-open at f/2, but it also boasts very decent image quality in other aspects as well. The same thing goes for very affordable lenses there’s no free lunch, right?Ĭonsidering how tiny and affordable this Rokinon 12mm f/2 wide angle lens is, you might expect it to have relatively terrible image quality. When any lens is extremely compact, oftentimes it sacrifices quite a lot of image quality and/or build quality. Autofocus (or Manual Focus & EXIF, for manual lenses)ġ00% Crop (Extreme Corner) | Fine-radius Sharpening Applied | (Maybe this could be sharper, but it’s much more detail than some “kit” lenses).Here is the rest of my lens review criteria: With that said, almost all photographers do have certain things in common when it comes to lens shopping: for example, sharpness is usually towards the top of the list. (You may have to go into your camera’s menu and turn on the function that allows images to be taken “without a lens mounted”, by the way.) So, unfortunately, the camera doesn’t know what focal length or aperture you are shooting at. In addition to lacking autofocus, the aperture is controlled mechanically via a ring on the lens, not through your camera’s command dials. If such details are a deal-breaker for you, then let’s make sure everybody is aware of this before we go any further: The Rokinon 12mm f/2 is a manual focus wide angle lens. Of course, different photographers have different priorities when looking for the perfect lens.įor example, sometimes autofocus is absolutely required, while other times, manual focus is actually useful, or even preferred.
