I was recently given the opportunity to test the 14mm ultra wide angle lens buy Yongnuo. I wasn't really sure what to expect because I have never used a Yongnuo lens before, and they aren't as well known as the bigger players such as Canon, Nikon, Tamron, Tokina , sigma.
What struck me straight away when I first opened the box was how heavy the lens was. I wasn't expecting it to be as heavy as it is, but it is made from metal rather than plastic, this gives the camera a fairly decent balance when hand-held, and on a tripod it sits rigid and firm.
So I went on a trip to the north west of Scotland, around the Durness Area. While up there I used this lens as much as I possibly could, and let me tell you it was no hardship. I really really enjoy using this lens. Having not used a lens by Yongnuo, I was worried about softness. I find it extremely sharp at a lower aperture, while using it wide open at f2.8 does reveal some softer areas out of the edges, though the subject focused on is pin sharp.
The Autofocus is really quiet, and quick, even in low light. In fact I have attached an image taken at night, so you can see the quality. There is a small amount of lens flare when shooting into the sun, or into lights, but nothing unmanageable.
I was also worried about Distortion, on such a wide lens, but it actually handles these angles really well, especially after some lens correction in post. I will attach some sample images for reference. The diagonal angle of view is about 114° , so an unbelievable amount of width in a frame.
The only drawback, is that it has large lens petals so that no filters can be attached, so I have been getting creative with my shooting.
All in all, I am really happy with this lens. I have used Ultra wide lenses before this one, by various manufacturers, and this one is right up there with the best. Ever since I took delivery of this lens, it has rarely been off of my Camera.
