Rokinon 12mm F 2 8 ED AS IF NCS UMC Fisheye Análisis | 54 Datos comparados

The Rokinon 12mm f/2.8 Full-Frame Fisheye Lens is an ultra-wide manual focus prime lens designed for specialty fields like urban exploration, astrophotography, extreme sports, and interior architecture. Retailing at around $492 to $499, it stands out by offering a massive 180-degree diagonal angle of view that squeezes in more vertical and horizontal space than competing fisheyes. On the plus side, the lens delivers exceptional, tack-sharp image performance with nearly perfectly flat field curvature from the center all the way to the extreme corners. It also boasts remarkably low coma, minimal vignetting, nice sunstars, low flare dots, and provides a highly budget-friendly, high-quality alternative to options that cost thousands of dollars. However, the lens has several design and feature drawbacks. It relies completely on manual focus, making it a "one-trick pony" that may alienate photographers who require autofocus capabilities. The physical construction also leaves room for improvement; its barrel is mostly plastic rather than metal, which may not satisfy users who heavily abuse their gear. Furthermore, the removable hood causes almost the entire body of the lens to spin, making it...

The Samyang 12 mm f/2.8 ED AS NCS Fish-eye is a full-frame manual-focus lens designed around stereographic mapping, an optically complex projection method rarely offered by contemporary manufacturers. According to the LensTip review, this unique mapping is highly prized because it produces a more visually pleasing 180-degree image, moderately curving straight lines and preserving original proportions in the corners better than other distortion-heavy mappings. The evaluation highlights an unbalanced optical profile, delivering exceptional sharpness alongside significant color and edge flaws. The prominent pros of this lens include its unique stereographic mapping capabilities, an impressive builds-quality, and a sensational image quality and resolution in the very center of the frame. Conversely, the primary cons consist of noticeably weak image quality on the extreme edges of the full-frame sensor, a high and distracting level of lateral chromatic aberration, and a less-than-impressive, busy bokeh presentation filled with concentric rings in defocused regions.

This full-frame 12mm f/2.8 fish-eye lens (sold under names like Samyang, Rokinon, and WalimexPro) offers a breathtaking, 180-degree viewing angle that compresses the physical world into an amazing spherical panorama. The reviewer praises its solid build quality, which features a durable metal lens barrel and a satisfyingly smooth focus ring. Functionally, the lens yields exceptionally sharp images, and while it is manual-focus only, it contains an electronic chip to transmit exposure data directly to the camera body. It proves to be an affordable, high-fun-factor tool that excels at capturing vast open architectural structures, tight stairwells, and dramatic, symmetry-driven landscapes. However, the lens has several distinct limitations due to its niche design. It relies entirely on manual focus, and verifying image sharpness through the viewfinder can become straining over time because the fish-eye effect heavily compresses details in the center of the frame. Because of its bulbous front glass element, photographers cannot attach standard screw-on filters, and the inclusion of a red aesthetic stripe on the barrel looks a bit odd when mounted on a Nikon body. Finally, the extreme distortion...

This Samyang 12mm f/2.8 fisheye lens review evaluates the manual-focus full-frame optic on a 50MP Canon 5Ds, emphasizing its unique stereographic projection geometry which creates a less compressed, more visually appealing 180-degree diagonal field of view compared to traditional equidistant fisheyes. The reviewer praises its robust, all-metal build quality, heavy 515g weight, smooth focus ring action, and a bright f/2.8 viewfinder image. Optically, the lens delivers high contrast, excellent flare control even with the sun directly in the frame, and complex aberration control that yields highly detailed images across the frame, especially when stopped down to f/5.6. The primary drawback highlighted is the lack of electronic contact pins, meaning the lens transmits no EXIF data to the camera and requires full manual settings for exposure, focus, and aperture control. The reviewer also notes that chromatic aberration (CA) is quite obvious in the corners at 100% crops, though easily fixable in editing software, and that vignetting is noticeable wide-open at f/2.8 before disappearing at f/4 <<...

The Samyang 12mm f/2.8 ED AS NCS Fisheye is a fully manual full-frame prime lens highly praised for its unique stereographic image projection, making it the widest diagonal fisheye lens available. This advanced optical design offers a less distorted, flatter image with minimized bulging in the center compared to traditional equisolid fisheye designs. Optically, the lens delivers high-quality, crisp results, featuring excellent sharpness in the center even when shot wide open at f/2.8, alongside good color and contrast. Its compact build (77x70mm) and light weight (515g) make it highly portable. Furthermore, its extremely deep depth of field allows for effortless zone focusing; for example, stopping down to f/11 ensures everything is sharp from 0.5 meters to infinity, completely bypassing the need for critical adjustments. The lens has notable drawbacks, primarily its lack of electronic components. It offers no autofocus, no automatic aperture control, and lacks an electronic autofocus confirmation chip to assist the photographer. Additionally, it can present light metering challenges on entry-level Nikon camera bodies. The physical lens cap fits loosely, and the extreme 180-degree field of view requires...

The Rokinon 12mm f/2.8 ED AS NCS FishEye is a solidly built, manual-focus lens with a metal body and a wide 180-degree diagonal field of view, utilizing a stereoscopic projection design that retains angles while compressing the center and expanding the edges. The reviewer notes several strong advantages, including excellent center-frame sharpness that remains crisp from f/2.8 through f/8, high contrast, and very minimal flare and chromatic aberrations. Additionally, the manual focus ring is well-damped, and the lens performs well for astrophotography at f/2.8 due to its well-controlled coma in the extreme corners. However, the lens comes with notable drawbacks, primarily its completely manual nature, which lacks electronic communication and causes exposure metering inaccuracies on Canon bodies where the camera underexposes by up to one stop below f/8. Its extreme 180-degree view makes it easy to accidentally include hands, shoes, or tripods in the frame, and the bulbous front element prevents the use of standard filters. Furthermore, there is noticeable sharpness softness in the extreme corners when shot wide open at f/2.8, requiring the user to stop down to f/5.6...

The Fstoppers astrophotography review highlights the Samyang 12mm f/2.8 Fisheye as a high-performing full-frame manual lens that offers a massive 180-degree diagonal field of view, making it an excellent tool for dramatic nightscape photography. A major pro noted in the field test is the lens's exceptional control over coma and astigmatism; even when shot wide open at f/2.8, the resulting star streaks are minimal and barely noticeable on a full screen. Furthermore, the lens boasts an excellent build quality, a spot-on infinity focus marker that simplifies nighttime operation, and stereographic distortion that is relatively straightforward to "defish" in post-processing compared to complex mustache distortion. Facebook ·Institute Conversely, the review identifies several notable cons stemming from its specialized fisheye design. The ultra-wide 180-degree field of view introduces extreme curvature distortion that can easily become a creative gimmick if not handled intentionally. Optically, the lens suffers from a distinct focus flaw across its frame: while the center remains sharp, you must focus beyond infinity to achieve sharp corners, resulting in softer edges in standard landscape shots. Additionally, its short minimum focusing distance...
