Yongnuo YN 14mm f/2.8 Super Wide-Angle Fixed Focus Lens Autofocus for Canon EF-mount EOS Cameras

There really isn't much to say, it's already been described in detail in the other reviews. Super sharp, great value for money, a bit difficult to focus, but it doesn't bother me much, since I use the good piece in landscape photography anyway, where the focus ring almost always remains at "infinity". On an APS-C camera (Canon EOS 600D), the image distortion is within limits and can be quickly corrected with two clicks in Lightroom. I'm completely satisfied, unfortunately the weather isn't cooperating at the moment... :) UPDATE: I was now able to test the lens on an EOS 6D. Sharpness is still good, but not at the edges, is also related to image distortion, the full format makes a difference in terms of focal length, and vignetting has also increased significantly compared to APS-C. A lot can be ironed out with Lightroom, digital photography just doesn't work without post-processing and the lens isn't designed for snapshots anyway. Be that as it may - I stand by my recommendation, even if some of the "professional photographers" have expressed themselves very negatively - if you are looking for laboratory quality, you are in the wrong price range here. PS: The outdoor pictures are HDR's composed of 3-5 photos, with minimal (standard) sharpening in Lightroom.

Now that I've used it once for my work, I can comment on it in my opinion. I use it for photos of interiors, cider houses, restaurants... also for close-ups of people where I need it to appear quite deep (a chef with a plate for example). The first couple of times I used it with a tripod so manual focus isn't a problem, use the Liveview to focus (everything looks so sharp no matter what parameters you use, it's hard to tell the specific focus point), i close the aperture at 7.1 or 11 and that's it, everything in the picture is perfect. For handheld photos it's easy to get the point by using an approximate hyperfocal and just closing in at f/5.6, a few extra shots just in case and no problem. It's not as comfortable as my 17-40L, with its ultrasonic focus of course, but at this price point let's see what other ultra angle you have...none. The brutal sharpness really surprised me. Very good picture quality for what it costs, impressive. The colors are very good, like any other good lens. Chromatic aberrations... What is it? I haven't seen any of them yet. The geometric distortion is very moderate for the angle as long as you take the photo from the right angle. For my work, many cider houses, not being able to put a good UV filter in front of it bugs me (there can always be accidents with people and drinks), but hey, extreme caution is required. It's slightly lighter than the 17-40 mentioned above, has a relatively small size and is very portable. The focus ring is very good, too long for close objects, and it rotates well and tightly, it doesn't move by itself. The aperture ring is the same. Since I'm used to using old manual lenses (with my analog cameras), it's not that awkward to use either. It doesn't have the plastic feel that other lenses give, it's well built without being a black leg, but it doesn't feel like you've just bought a toy. Due to the case's shape, which serves its function well and is easy to put on and take off, the built-in sunshade will soon be covered in scratches, but hey, that's nothing. Of course, I hesitated for a long time before deciding to buy it (it was the historically low price that made me do it), but I don't regret it in the least. For its characteristics, not for constant use or to "tie it to the camera without removing it" but for whatever use I give it and at this price... I can hardly ask for more. Nice birthday self gift :)

use the lens on my Canon 5d II full format camera - I am very satisfied with the imaging performance. Of course there is vignetting with an open aperture of 2.8 - but you hardly take pictures with it anyway. There are certainly better lenses - but you have to put down at least twice as much and therefore I can only recommend the lens to everyone who wants to use it from time to time. Anyone who needs a UWW professionally should take a look at the 11 or 15 mm from IRIX.

I started with astrophotography and was looking for an ultra wide angle lens with an aperture below 3 for milky way photos. On some websites this was recommended for beginners and for the price it is also affordable for hobby photographers. I am very happy with it and would recommend it to anyone

Bought in 2023, after a long time I feel like giving a review because it is the best lens of my kit. It has been used on Canon APS-C and now full frame Sony and has allowed me to take great shots home. Since it's wide-angle (so with a wide hyperfocal) you don't have to spend money to buy the autofocus version and the focus ring allows you to set focus very precisely and fluidly, but I'm sure that You will keep it in an infinite position 90% of the time. The other ring of the cone port is very useful and well made, with clicks that are easy to "hear". The sharpness is great, it loses slightly in the corners in full frame, but still remains excellent. Vignetting isn't a problem at all and closing the aperture at f/4 isn't as noticeable. I didn't notice any discrepancies in any of the many recordings. The aperture of f2.8 allows this lens to be used even in low light conditions or for those who want to take their first steps in the world of astrophotography. The downsides are minor and negligible: the outward weight distribution, the fixed lens hood, and the aperture ring partially covered by the built-in flash. I think this is the first lens to buy for those who want to "ditch" the kit. You will always carry it with you.

For the price you can't complain. I use the lens on my Sony A7S2 with an adapter and I find the imaging quality very good. It's also good for videos to be easy to trade. A little tinkering with the software and the results speak for themselves. The processing is good I am satisfied. I can recommend it.

bought this lens with some apprehension. I'm a bit of a purist when it comes to my lens collection and apart from one Sigma item I only own Canon glass. I own a Canon 550D and have never felt I could get a wide enough lens (that was also compatible with a full frame camera) for a reasonable price. A friend of mine owns the Canon equivalent of this device and it has always made me jealous. Since it's only about 15% the price of a Canon lens, I didn't have high hopes for the quality of the stills (or movies) this thing would be capable of. How wrong could I have been. For the money, this lens is just amazing. Wide but also very sharp at 100% crop. I am quite amazed at how good this product actually is. At this point (a week of extensive testing) I don't regret buying this lens at all. It works very well for pictures and videos (which is what I mainly use my camera for). Build quality feels solid, my only downside is that the focus ring on my device is a little rough in places. I also don't think this unit will stand the test of time as well as my Canons, although I'm not sure why I think so. In fact, using the lens is also a bit more complicated than its more expensive counterparts - as you've noticed in the description is the full manual; focus and aperture. I can understand that this isn't for everyone, but it didn't pose any major problems for me. Focusing can be a little tricky at times, but having Magic Lantern on your camera can really alleviate that difficulty. When you factor in the price of this kit and the price of its closest competitor, it's a no-brainer. At least it is for me. Looking at the comparison shots of this and Canon's 14mm counterpart, there's only a negligible difference in favor of the Canon. For a £1700 difference it's really not worth it in my humble opinion. If you need a wide angle lens, get this lens. You will not be disappointed.

Very good lens from K&F Concept, highly recommended. Really very sharp and has a good image quality, super combo with my Canon 600d. Processing top, you can focus super manual.

I'd like to provide a brief explanation to this review to put things in context: First, I'm an experienced photographer with years of practice, experimentation, and mastery (or at least attempted mastery) of various areas of photography. I know how equipment works and how to test a lens in my own home. Second, I'm not an impulsive buyer. In fact, I prefer to examine every aspect of something before hitting the buy now button. I'm sure there is a name for this condition. For these reasons, when I ordered this lens I was fully aware of both the amazing and disappointing experiences other people have had with it. However, when ordering through an Amazon (Fulfilled by Amazon) retailer I was confident that should I be able to test it properly and it appears faulty I would be able to exchange it for another copy. I had read so many positive things about this lens (the price, the sharpness wide open and the lack of coma - which is so important in astrophotography) but also some negative reviews (most common and notable the number of copies show decentering of lens elements causes uneven sharpness across frames and sloppy focus scale calibration). 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 to help you test a new lens so I won't bore you here. However, it is definitely worth noting that the sharpness/ decentration test ended up going very well. Working with such a wide-angle lens is not easy. So if you arrive through your mailbox with one of these, please note... Try twice, return once. Initially there seemed to be some decentration when viewing images of a flat wall at 100%, like any good new lens owner I went back to the tripod and tested again. It appeared that I did not have the camera aligned horizontally to the plane of the exam the first time, as corners were much sharper the second time around. Not perfect, but better. Next came the focus scale calibration test... set up on a tripod and focused (using Live View) on various objects at different distances on the scale. Surprisingly very accurate at short and medium ranges - a nice surprise given some of the reviews I read. Next came the most important test for astrophotography... infinity focus. A lot of the bad reviews I read stated that the infinity focus was way off the mark on the lens focusing scale. So I focused on a distant tree using Live View. Hmmm, at first I was worried that my new lens, which has been good so far, wasn't quite focused at infinity. In fact, it felt like true infinity was occurring AFTER the focus stop (contrary to the reviews I'd read which suggests some copies were focused in an infinity way before the infinity mark on the lens) A 100% review on the monitor was inconclusive. This left me with only one option - go shoot some stars. Well, to cut a long story short, the day after this lens arrived I found myself on a hilltop in the black of night with my tripod, new lens and shutter button... Heaven! Using Live View (and the appropriate camera settings), I focused on a bright star next to the Milky Way (reaching just a little past the infinity mark on the focus dial), released the shutter, zoomed in on the image on the back of my camera, and was blown away. When I got home and looked at the image at 100%, I could see some slight decentrations in two extreme corners at 100%, but nothing to worry about at all. The importance of the lens's ability to focus on infinity (the stars) had been proven. It's sharp and wide enough to capture a large portion of the Milky Way. In short, this lens is not perfect. But it's easily good enough to become a long-term keeper for me. I've tested it and I know it will take the pictures I want it to take. It has my trust. 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 K&F Concept acted on the feedback regarding the Infinity focus and implemented a process in their quality control workflow to ensure they ship with accurate focus scales.

If you can live with a purely manual lens, you can get a very nice, sharp and high-contrast lens here for little money. You have to stop down a bit so that the edge is sharp, but that's a really small downer.
