The first image is shot at F 2.8, ISO 1600, shutter speed 15 seconds and focus set at my infinity pencil mark.  Practically, this means that almost everything in front of the camera will be in the frame. I have two other Rokinon lenses (14mm and 35mm) where the markings are pretty far off from the true distance. The body is the typical mix of metal and engineered plastics, but it has a very handsome finish. The Canon compatible version that I have weighs 515g, and balances nicely on my Canon 5D III Camera Body. The f/2.8 maximum aperture is effective in low light situations and enables some measure of shallow depth of field control. Infinity focus is reached quickly after 4 ft. If you can adjust to their quirks, the image quality can equal or even exceed that from lenses several times their price. Rokinon 12mm F2 SC is about 1/2 times more expensive, however it's massively available on the used lens market. The Fuji 14mm f2.8 is also smaller and lighter than the Rokinon 14mm f2.8 and besides landscape shooting it makes an excellent travel and walk about lens. Samyang/Rokinon 12mm f/2.8 ED AS IF NCS UMC Fisheye Rokinon 12mm f/2.8 at a glance: EF Mount/Full-Frame Format Aperture Range: f/2.8 to f/22 Three Extra Low Dispersion Elements Two Aspherical Elements Nano Crystal and UMC Lens Coating Manual Focus &… The fish-eye image mapping can be seen clearly as my trees are not really curved. The Rokinon 12mm F2.8 ED AS NCS Fish-eye Lens provides a 180º diagonal angle of view on full-frame cameras for an ultra-wide angle, distorted perspective that is useful for architectural interiors, landscapes and creative experimentation in any photographic application. Interior Architecture is a potential use for an UWA lens; however, Fish-eye lenses are not going to be a hit for architectural photographers because of the extreme distortion. The f/2.8 maximum aperture is … Sturdy metal barrel with removable petal-shaped lens hood. You will see a lot of curved lines and bent shapes in images but that is the intended image mapping for this lens. For now, its just something I will be aware of when using wide aperatures. For astrophotography, coma is an important parameter and one that Rokinon (and lately Sigma Art Lenses ) has excelled at in the past. The second interesting thing that happened with this sequence of images is that using aperature priority mode on the camera (camera set shutter speed and I manually set F-Stop), the images get brighter and brighter overall moving up from F 2.8. The first is from the upper Right corner, the second is from the upper Left corner, and the third is centered on the upper edge. The Rokinon 12mm f2.8 fisheye for Nikon is definitely sharper than my manual focus Nikon 16mm f2.8 fisheye. This instantly disappears if you click the box “remove chromatic aberrations” box in the lens corrections section of LR. The top center crop is not showing any visible coma. Nano crystal coating and ultra multi-coating on the lens elements improves light transmission and reduces ghosting and flare. I ask that you respect my images and only download for personal, non-commercial use; no reposting or printing permitted of the complete image or any derivative of the image. This will never become your Macro lens, but it is able to produce sharp images of objects close to the glass. The aperture ring moves nicely and has well defined clicks for each half step (full stops are labelled on the ring). Toes and tri-pod legs can also get in the way. I’m posting some photos for you to decide for yourself if the lens meets your needs. Above is a quick, hand held shot off my deck using thru the view finder focus (so its a little soft). I suppose I should mention I've a Samyang 8mm f/2.8 and a Rokinon 12mm f/2, both black in X mount.  I put a pencil mark on the focus ring at true infinity focus so I can find it quickly without actually having to go through the live view procedure. Another question is how accurate are the markings on the focus ring? There are no electronics in the Canon version of this lens and no electrical contacts on the rear face. This is a beautifully designed little lens. If extreme corner sharpness is important, then shooting at F 5.6 or F 8 will produce outstanding image sharpness over the entire frame. The stops at both ends of focus are slighly soft, like coming to a stop against a compliant pad. It clicks firmly against the lens mount with no noticeable side to side play and only a slight amount of rotation play, no more than any of my other lenses. ​The 12mm f/2.8 ED AS IF NCS UMC Fisheye Lens from Rokinon provides a 180º diagonal angle of view on full-frame cameras for an ultra-wide angle, distorted perspective that is useful for architectural interiors, landscapes and creative experimentation in any photographic application.

It is very compact at only 2.33″ long (59.1mm) with a diameter of 2.85 inches (72.5mm). One way to focus is to  estimate distance and to simply set the focus ring using the distance scale (prefocus) . But from this admittedly small sample, flare does not seem to be a major issue. With the closeest part of the door about one foot away and the fartherest part of the door about 7 feet away, I was’t sure that light reflected at these extreme angles would give me a good measure. Rokinon 14mm f/2.4 3.  Also, the sun is behind some light clouds with blown-out highlights in the clouds. The lens cap provides adequate protection of the bulbous front element of the lens. Rotation is damped just right and has consistent resistance throughout its travel. The Rokinon 18mm F2.8 AF Sony E ($399.99) is a svelte lens with a big, wide view. Also easily corrected.

Indeed the measurement did not make any sense. Although specifically designed for crop sensors, this lens can be used on full frame sensor and micro 4/3 cameras, but with a different effective focal length. The Rokinon 12mm fisheye lens takes us to another level of lens performance and user experience. The 12mm is a great match for the latest cameras like the Fuji X-Pro2, X-T2 and Sony a6300. Its tight, but will twist off. The first result was a measured vignette from center to corner of about 1 1/2 Stops at F 2.8 and gradually improving to about 1/2 stop at F 8. I did not make any contrast or clarity adjustments. Extra low dispersion and aspherical lens elements reduce aberrations for sharp, color-accurate imaging. Two times more expensive Rokinon 12mm F2 or four times more pricy Fujinon XF 14mm F2.8 will definitly deliver significantly beter image results. I set up on a tripod and exposed through the F-Stops using aperture priority and manually setting the stops. Below is a shot (at ISO 100) of an interior with wood beams.

Here is the order in which they will appear below: 1. Shooting at F 4 did not change things much, except for losing the stop of light. Focus is achieved without any lengthening or rotation of the front lens element, Low Chromatic Aberration: All colors to come into focus in exactly the same place for reduced color fringing and increased sharpness, Helps prevent haze, lack of contrast and artifacts scattered throughout the image from bright source(s) of light, Helps prevent a blur that looks like a comet's tail that can occur at a lens edge, State of the art antireflective technology utilizing ultra-low refractive index Nano particle coatings for optimum contrast, light transmission and control of ghosts and flare. I checked this lens at 3 ft (measured from sensor plane to target plane) and at 1 ft. The lens has such a broad DOF that it is difficult to tell where focus is sharp when looking through the viewfinder. The Rokinon 12mm F/2 performs very well; especially for the price. It feels rather dense for its size, presumably from the 12 element design. But my Rokinon lens doesn't focus properly with the viewfinder focus indicators.  It’s probably too soon to make a sweeping conclusion here, but so far, so good. The lens is designed to give a non-rectilinear image mapping so it would be difficult to separate out any unintended distortion. Photographers can now appreciate high image quality with quiet, silky smooth and … I was able to get a gray patch of fog that fit from center frame to a corner, and the spot light meter was telling me that there was only about 1/3 of a stop of brightness difference in the fog over the expanse of interest. The lens is somewhat smaller than I expected for a F2.8 UWA. But, the watch face itself is very sharp. Some exposure adjustments were made in Adobe Light Room so the brightness was fairly close in each expansion. The closest competitor to the Rokinon 12mm f/2.0 was the Zeiss Touit 12mm f/2.8. Circles around the center of view will remain circles. Most of the focus turning range occurs between about .66 ft (minimum focus distance) to about 4 ft on the scale. The Samyang / Rokinon 12mm f/2 is a good example of how a lens can be a good investment, no matter how old it is.
