The Samyang 14mm f/2.8 Aspherical Wide Angle Lens is an excellent addition to any photographer's collection. It allows users the ability to expand their creativity and capture incredible scenes from a truly unique perspective. This manual focus lens creates images with an expanded perspective and sharp focus that extends throughout the entire frame.
Optical construction is based on 14 elements in 12 groups. 2 ED low dispersion lenses, one hybrid aspherical element and one glass aspherical element combine to minimize distortion and chromatic aberrations. Advanced optical construction allows this lens to deliver razor sharp images even in the corners. The 14mm f/2.8 works perfectly even with latest high resolution, full-frame sensors. The lens is optically corrected, which is especially useful in architecture and landscape photography, and the 114 degree angle of view allows the user to create extremely unique and interesting pictures.

Top customer reviews
I had read so many positive things about this lens (the price, sharpness wide open and lack of coma - which is so essential for astrophotography) but also some negative reviews as well (most frequent and notable the number of copies exhibiting decentring of lens elements causing uneven sharpness across the frame and the sloppy calibration of the focus scale). It was with apprehension and a nervous optimism that I opened the box when the package arrived a few days ago.
There are many online resources that will help you with how to test a new lens so I will not bore you with it here. However, it is definitely worth noting that the sharpness/decentring test went very well, eventually. Working with such a wide angle lens is not easy, so if you end up with one of these arriving through your letterbox take note... Test twice, return once. Initially, there appeared to be some decentring when viewing images of a flat wall at 100%, so like any good new lens owner I went back to the tripod and tested again. It appeared that I had not aligned the camera horizontally to the plain of testing the first time as corners were much sharper the second time around. Not perfect, but better.
Next came the focusing scale calibration test... set up on a tripod and focus (using Live View) on various objects at different distances on the scale. Surprisingly very accurate at short and mid distances - a lovely surprise considering some of the reviews I had read. Next came the most important test for astrophotography... infinity focus. Many of the bad reviews I had read stated that infinity focus was way off the mark on the focussing scale of the lens. So I focussed on a distant tree using Live View. Hmmm, initially I feared that my new lens, good so far, was not quite focussing at infinity. In fact it felt like true infinity would occur AFTER the focussing stop (contrary to the reviews I had read which suggested that some copies focussed at infinity way BEFORE the infinity mark on the lens) A 100% check on the monitor was inconclusive. This left me with only one option - go and shoot some stars. Well, to cut a long story short, a day after this lens arrived I found myself on top of a hill in the pitch blackness of night with my tripod, new lens and shutter release... heaven! Using Live View (and the appropriate camera settings) I focussed on a bright star next to the Milky Way (achieved only slightly past the infinity mark on the focussing scale), released the shutter, zoomed in on the image on the back of my camera and was blown away. When I got home and viewed the image at 100% I could see some slight decentring in two extreme corners at 100%, but it was nothing to worry about at all. The importance of the lens' ability to focus on infinity (the stars) had been proven. It's sharp and it's wide enough to capture a large portion of the Milky Way.
In short, this lens is not perfect. But it is easily good enough to become a long term keeper for me. I have tested it and I know it will make the images I want it to make. It has my confidence. If you are like me and have read all the reviews and done all the research (and are reading this review now to try and help you make a decision) just go for it. My guess is that Samyang have acted on the feedback regarding infinity focus and have introduced a process into their quality control workflow to make sure they are shipped with accurate focussing scales.
I'm usually the first person to pay the extra money and stick with OEM kit but I'm glad I went for this. Good solid build quality, a beautiful big bulbous front element, and an integrated hood. The focus ring is smooth without being too light, and its great having a proper aperture ring (for when I use this with an adaptor on my NEX 7).
As anyone who is considering this lens should know, using a wide angle like this does need care. You're more likely to use this in a slow methodical manner and often on a tripod so i consider manual focus not an issue. Do note however that the distance markings on the lens for focusing are way off. Also, the throw of the focus ring is so long that for a good portion of the turn the focus indicator in your viewfindee will tell you you're 'good to go' but in reality you are only fully in focus at one end of this indicated "in focus" movement. So, 'chimping' will be required to make sure you're fully happy until you get used to this. Again, I dont consider this a major issue for how i'll be using this lens but its still a bit annoying which is why i knocked off a star.
The reported and dreaded (hard to fix) moustache distortion is evident if you take shots with clear horizontal lines going across the frame. By my standards, you dont notice if for 'natural' landscapes but if you go taking shots of buildings it could well cause a problem. I believe it is now possible to download a correction profile for this but please check this yourself though. You will NOT be able to fix all of the distortion by simply applying a bit of "pincushion" like you could do with reasonably good results on some other wide angle lenses.
Relatively cheap (I believe the cheapst way to go this wide on full frame)
- Very good build quality and it looks good (doesn't look like a cheap peice of crap on the front of your camera)
- Good image quality
- Aperture ring
- No good for taking quick shots. You'll have to carefully optically focus AND zoom check afterwards to fine adjust.
- Dodgy distortion if you mainly want it for architecture
- Like the Nikon 14-24, the design of the front element does not allow the use of any round or square filters (unless you pay hundreds for the special Lee custom set up)
Hope this helps
Of course it's fully manual but for most landscapers thats no big deal. I use manual focus and exposure all the time and so should you if you want make the most of your images. This lens pushes you to think which for me helps with creativity.
