Neither the camera nor the tripod were moved between shots. In this video episode I take a look at the overall build and handling of the lens. Some people don’t mind them, but personally, I’m not a fan of any filter larger or more complicated than an 82mm screw-in filter. (On Canon 6D). I did that to simulate the technique of focusing on a faraway object (like a star, for instance) while shooting at night. Although I am a Technical Engineer and I am constantly explaining to my students how to do technical laboratory tests, I thought that if it was just to submerge readers in technical data, the various brands are there to do that, so I am going to carry out a real comparison between the Irix and the Samyang, or at least I am going to try to. Whether you’re a landscape photographer, a nightscape photographer, or an in-your-face portrait or action sports photographer, you might be in the market for an ultra-wide prime lens. Two of these Rokinon 14mm lenses are extremely portable compared to any other lens (DSLR or mirrorless) that can hit such a wide focal length and fast aperture. I was extremely careful not to touch the focus ring at all after achieving critical focus. If you hate seeing “wings” on your stars in the corners of your nightscape images, get any of these lenses. Still, it’s a great alternative to any of the ultra-wide zooms out there. However, there are 19 sunstar points and they’re still not the classic, thin, sharp-pointed stars that I like to see. But is that enough? Rokinon 14mm f/2.8 ED UMC, Canon 6D | Vignetting & Distortion Sample: The noticeable mustache distortion is not just at the very edges. With any 14mm lens, shallow depth is not easily achieved unless the subject is very close to your front element. If you think about it, moustache distortion causes objects in the middle of the frame to arch upwards slightly. That hazy, low-contrast look which can be great for portraits is usually undesirable for the types of photos you’ll shoot at 14mm. Next came the more exotic Rokinon/Samyang 14mm f/2.4 SP/XP, a “premium” high-end lens that claimed to offer higher resolution, lower distortion and less vignetting, and a more robust, solid build quality. Clearly the Rokinon 14mm f/2.4 SP has a problem with the right side of the frame. The Rokinon 14mm f/2.8 AF is somewhere in the middle. Slightly different fields of view (FOV), despite both lenses being 14mm, which could have to do with…. Samyang/Rokinon have released “MK2” (AKA “Series II”) versions of their popular manual focus 14mm f/2.8 and 85mm f/1.4 lenses. The photos below are both completely boring (it’s Oregon in the winter, what can I say?) As mentioned before, the Rokinon 14mm f/2.4 SP  retails for $999, versus $299 for the old f/2.8 version. ), Lastly, we’ve just seen the release of Canon, Nikon, and Sony mount Rokinon 14mm f/2.8 AF lenses, part of Rokinon’s dive into the realm of autofocus! Regardless, we’ve gotta wrap this up with something. I will be taking photos of my home town with the two lenses and will compare the experience of using one agains… It’s incredibly sharp, has low vignetting, low distortion, and only a faint bit of coma. Rokinon 14mm f/2.8 AF, Canon 6D | Coma Test, 100% crop of upper-left corner – Again, essentially none. Here’s where things get weird. Less distortion, for sure, but we don’t know if that means less astigmatism for star photography yet. I proceeded anyway, with the following photos, both taken at f/2.8, ISO 100, 1/250th of a second. It can be cool, but it’s not the classic “sharp point” sunstar look. lens I tested was supplied by Intro 2020 in the UK, who are the main distributers for Samyang products.Buying the SP/XP 14/2.4 All three of these 14mm lenses are impressively sharp, even wide open at f/2.8, from the center to past the rule-of-thirds area. The brightness may be partly due to the vignetting on the older f/2.8 being so extensive, which leads to my next point…. Nightscape and wide-angle astro photographers have a number of choices for lenses and gear that they didn't have before and NatureTTL has put … Fortunately, that seems about to change, and leading the charge is Korean lens maker Samyang (also sold as Rokinon) with this lens – the Samyang AF 14mm F2.8 lens in an RF mount. Rokinon 14mm f/2.8 ED UMC, Canon 6D | Vignetting & Distortion Sample + Correction Profile | Significant vignetting and mustache distortion, Rokinon 14mm f/2.8 AF, Canon 6D | Vignetting & Distortion Sample + Correction Profile – Significant vignetting, minor barrel distortion, Rokinon 14mm f/2.4 SP, Canon 6D | Vignetting & Distortion Sample + Correction Profile – Significant vignetting, minor barrel distortion. In case it wasn’t obvious, the sheer diversity offered by Rokinon’s trio of 14mm lenses is impressive and commendable. As you might expect, the Rokinon 14mm f/2.4 SP has the least vignetting at f/2.8-4. Their very first optical design was the “nifty fifty” of ultra-wide primes, the manual focus Rokinon 14mm f/2.8 UMC. (On Canon 6D). It’s got image stabilization, too, something that no other ultra-wide ~14mm lens has unless you count sensor-based stabilization. (Source: Samyang.) Mark this one “unresolved.”. Rokinon 14mm f/2.4 SP, Canon 6D | Coma Test, 100% crop of upper-left corner – To date, the best coma performance of any 14mm prime lens ever? Milky Way over Eastern Sierra, California, 2014 | Rokinon 14mm f/2.8 ED UMC, Nikon D800e | 277 sec (earth) 30 sec (sky) at f/2.8 ISO 1600. I have to see improvement in these wide apertures to justify making a purchase like this. All photos were exported as web-res jpegs with no output sharpening. Metering, for example, would sometimes be off, due to a lack of electronic com… (On Canon 6D), In the extreme corner, the oldest Rokinon 14mm f/2.8 ED UMC is a bit soft until f/5.6-8. Or is this how this is supposed to look? Which begs the question: Is there also something wrong (just not as badly wrong as the right side) with the part of this lens that renders the left side? Here’s an approximate 100% crop from the area that I focused the lenses. Even in bad light, it still nails focus just as consistently as a name-brand lens. In one corner, we have the Rokinon 14mm f/2.4 SP which is built very solidly. This is an autofocusing lens (and one that autofocuses very well on the Canon EOS R that I tested it on) along with having a beautiful, weather sealed build. *Update*  I never did follow up to receive a second copy of this lens after sending the first one back. All three Rokinon 14mm ultrawide primes are what I’d call “ridiculously sharp” in the center, wide-open at f/2.8. But again, not true at f/2.4. From an aesthetics standpoint, which I honestly care almost nothing about, the 14SP is a nice-looking lens and was clearly designed with Zeiss’s external look in mind. Samyang 14mm F/2.8 ED AS IF UMCがSamyang Premium MF 14mm F2.4よりも優れている理由は何ですか? 無限にフォーカスすることが出来ます 239g より軽い 552g vs 791g Autofocus on an ultrawide lens isn’t very necessary, though, for many types of photography. The ultra-wide-angle Rokinon 14mm F/2.8 is useful when shooting videos at night. On this copy, f/2.4 seems to resemble f/2.8 on my old Rokinon lens pretty closely as far as vignetting and sharpness go, although the new lens has better color and contrast. The sunstars (at f/~4) are impressively close to the classic sunstars of yesteryear’s un-rounded aperture blades. (Do your own testing!). Less astigmatism: Maybe? I should probably preface this review by saying that I loved the Rokinon 14mm f/2.8 when it first came out. Irix 15mm f/2.4 Firefly & Blackstone: If you’re willing to go with a slightly less wide focal length, Irix has an interesting offer: Two versions of the same lens. That’s 2/3 of a stop difference in shutter speed. These two photos were taken about two and a half minutes apart, so it’s entirely possible that the scene lightened or darkened slightly in that time. With that in mind, if you’re doing wide-angle macro photography, any of these lenses will have decent bokeh. Even though they’re duller at f/8-16, I found myself reaching for the AF 14mm f/2.8 for any urban or cityscape scenes that had pin-point lights in the image. A brighter overall frame (less vignetting). Unlike the older f/2.8 version, the SP version doesn’t have a manual aperture or manual aperture ring: The aperture is controlled electronically via the camera body. A reduction in astigmatism/field curvature, which was my main criticism of the original Rokinon 14mm f/2.8. The SP 14mm f/2.4 has nine aperture blades, and therefore its sunstars are a little more pointy. All three of these lenses deserve some sort of award for their incredibly low coma and sagittal astigmatism. Samyang 14mm f/2.8 Vs Samyang 24mm f/1.4 for milkyway in Canon EF and EF-S Lenses Approve the Cookies This website uses cookies to improve your user experience. See the full review here. A usable wide-open aperture. The optical construction is 14 elements in 10 optical groups with 3 high refractive index elements, 2x ED element, an aspherical hybrid element plus a aspherical glass element. Well, I’m a star photographer, and this would primarily be a “star photography lens” for me. The products in this post may contain affiliate links. The Rokinon 14mm f/2.4 is still decently portable, despite being the biggest and heaviest of the trio, and its build quality is absolutely worth the heft. (Note: The crops don’t line up exactly because the field of view and distortion in each lens are slightly different.). All 14mm lenses have a lot of vignetting wide open. Solid at f/2.8; fantastic at f/4. Truly, only star photographers hope to use these wide-open apertures. Sigma 14-24mm f/2.8 Art: This rather new ultra-wide zoom lens from Sigma is utterly monstrous, but it also offers more than just 14mm. The SP stands for Special Performance. The AF and SP/XP 14mm lenses do have some metal in their construction, but all three lenses have plastic, non-detachable hoods. Rokinon/Samyang's first autofocus lens for Canon EF-mount is the 14mm F2.8, a variation on the company's existing 14mm F2.8 FE for Sony with a different optical formula. They do have a bit of chromatic aberration in the corners, but that’s again easily corrected with a lens profile. This used to be a terrible thing for nailing precise focus on anything, but these days it’s impressively precise. Still, for the purposes of this comparison, we have to draw the line somewhere. A primary reason to want this lens is because it has a 14mm focal length and the focal length largely determines the type of photography a (or any) lens is used for.The ultra-wide 114° angle of view presented by the 14mm focal length is both very useful and extremely fun to use. However for some weird reason, at f/4 or so the sunstars are awesome, sharp pin-points! There are a lot of other lenses that hit 14mm and f/2.8. Unfortunately, all of them do have quite a bit of vignetting at f/2.8. The decision is all about your priorities as a photographer, and it should already be clear: if you rarely even use 14mm, and just want to “cover the bases”, then get the Rokinon 14mm f/2.8 UMC.
