Samyang 14mm f/2.8 overview

  • 1Description

A bright and versatile ultra-wide prime, the Pentax K-mount 14mm f/2.8 ED AS IF UMC from Samyang features a bright f/2.8 maximum aperture and is well-suited for subjects ranging from landscape to architecture to astrophotography. The optical design incorporates a pair of aspherical elements and three high refractive index (HR) elements, which control spherical aberrations and distortion. Additionally, two extra-low dispersion elements are used to reduce color fringing and chromatic aberration for improved clarity and color accuracy. An Ultra Multi-Coating has also been applied to limit flare and ghosting for improved contrast and color rendering in strong lighting conditions. This manual focus prime has an 11" minimum focusing distance and also features a built-in petal-shaped lens hood to guard against flare and protect the front element.

Wide-angle prime is designed for full-frame Pentax K-mount cameras, however can also be used with APS-C models where it provides a 21mm equivalent focal length.
Bright f/2.8 maximum aperture suits working in a variety of lighting conditions.
Two aspherical elements and three high refractive index elements control spherical aberrations and distortion in order to produce greater sharpness and accurate rendering.
Two extra-low dispersion elements minimize chromatic aberrations and color fringing for improved clarity and color accuracy.

    Samyang 14mm f/2.8 reviews

    14mm f/2.8 ED AS IF UMC Lens for Pentax K is rated 4.8 out of 5 by 5.
    Rated 5 out of 5 by from Sharp for the price In deciding which wide angle lens to buy, I read quiet a alot of reviews online before making my decison.This lens is sharp from 2.8 across the frame. I was quiet impress with the quality when I compared it with glassess of above $1000. It upheld the popular opinion and I am a testimony to that. It is sharper than my tam 90mm, fa 31mm, zeiss 85mm.On the slip side, there is high vigenetting at max aperture, but that is not a show stopper. by 5.6 it is almost free of this con. Aberation is really low.But the main worry is the distortion. It is a prominent feature of this lens. The distortion is wavy and will difficult to correct. For me, it is ok since mmy primary use for this lens is land scape, I can use PT correction to bring my photographs to a acceptable level in term of distortion.The front element does not take filters and can easily get scratched. Getting a filter a lee or fotodiox filter is almost or even more expensive than the lens itself. The front element also calls for caution because of its bulging nature. I will also like to say calibration is perfect on my K5. Although it has no auto focus, focusing is easier than my zeiss glass.

    Rated 5 out of 5 by from Awesome lens at bargain price! What is there not to like about this lens? If you have never used a manual focus lens brave. The focus confirmation chip will be of enormous benefit to begin with, but honestly, with a 14mm focal length, the focus scale on the lens is all you need. The results from f2.8 all the way to f16 are astonishingly sharp (f22 only very sharp)! Minor vignetting wide open is corrected by one click in Lightroom (if needed) and is not apparent once you stop down to f4. Both of these minor issues are explained by the laws of physics and apply to lenses 4 to 5 times the price. Build quality is as good as any lens I have owned over the last 40 years, with a smooth as silk focus ring. This is an incredible piece of glass for the price! Thanks to the B&H team for the equally great service. Phil, Hobart, Australia

    Rated 5 out of 5 by from Sharp beyond my expectations I got this for my Pentax K1 and to do all my ultra wide work. The first copy had a mis-allignment issue so I sent it back. Thanks to B&H's no hassle exchange policy. I got a second copy that is simply superb. The image quality of this lens is pro-class, hands down. Yes it does have a distortion issue but the fix is a simple click away in Photoshop or Lightroom.

    Rated 4 out of 5 by from In the end a great lens. First copy of lens was misalaigned. B+H promptly replaced it with one which was properly alaigned, but would not focus to infinity. I guess I could have returned that one to. But apparently this issue is common for this lens and I performed a simple callibration procedure to get it to focus to infinity. OK, so thats pretty terrible in the quality control department. This latter issue may be particular to the Pentax K-Mount variety of the lens. I'm not sure. However.... Once I got the lens to focus to infinity... it turns out to be a very decent lens. At f/2.8 is a bit soft, and there is some vignetting visible. However even at f/3.2 it sharpens considerably and contrast increases considerably as well. From f/3.5 - f/7.1 this lens is very sharp I would say that f/5.6 is the sweet spot. With these super wide lenses focusing is always a challenge, I think once you do some initial tests / callibration to get the distance scale to make sense, its VERY easy to use. Pretty much any subject beyond 10 feet may as well be infinity, as at 14mm the hyperfocal distance is very close. But the distance scale ON the lens is somewhat useless the way it came. The build quality is very high, it feels very solid, everything is very smooth and tight. So not a cheap feeling lens, just an inexpensive lens with good optics. In testing this with a star field, at f/2.8 there is some degree of comatic aberation. This greatly improved with stopping down to f/3.2. And at f/3.5 was vertainly better than most lenses I have. I think if you can forgiv the journey to getting a working lens... it should be a great lens for the demanding work of astrophotography. Again, for the price needs to be added to these comments. In terms of CA, purple fringing, and flare, its minimal, by f/3.5 CA is not really noticeable. As for distortion, there is distortion, but nothing I could not completely correct with fulla - which is all I care about given I use the lens for panoramas made with Hugin. For little planet panoramas, I have had very good success with this lens and using Hugin for the panoramic workflow. Just 8 or 10 shots to get the whole world sphere. However, Samyangs inattention to the easy to get right finishing touches, such as callibrating the hard stop at infinity, and having a distance scale which is accurate for the camera mount, is really unforgivable. Letting the first lens leave the factory is a sin as well. Obviously a lot of work went into getting the glass right, then only to fall over with poor QA on what should be easy the mechanical aspects of the lens.

    Rated 5 out of 5 by from Just Buy It! I've been considering this lens, and it's variants (Rokinon, Vivitar and Bower), for several months. I've researched many reviews on this lens prior to purchase. I shoot a Pentax K-50. Common issues were lens distortions, the distance scale being inaccurate and quality issues, where some users needed multiple copies before finding a good one (largely dealing with edge sharpness). Though I should mention that as for lens distortion it's less on a APS-C sensor. Well I bought the lens with the intention of putting it through a test before the B&H return policy expired. I took the lens to the Washington National Cathedral and the Balitimore Railroad Museum. In short, I was blown away by it's performance. It was incredibly sharp, even in corners, wide open. The distance scale on my copy seemed fairly accurate. The color and CA was excellent. Yes there is some lens distortion particularly indoors, but I found this easily correctable with PTLens. Focusing through the viewfinder, at other than infinity, can be somewhat challenging, but the work around I found is to use live view and magnify the image to get a precise focus. While the lens doesn't take filters per se, for outdoor landscapes I use a Lee 4 X 6 .9ND Graduated Neutral Density filter. In short, just buy this lens! It has a a few nuances, but it's cheaper, faster and sharper than comparable Pentax versions or other brands.
