Sigma 14mm T2.0 Canon EF Mount Lens

I just purchased this lens and it is far better than what I expected of it. The quality of the body is well built, strong and durable. It is a little heavy to carry but at the same time it gives you a sense of of having a better lens compared to those built of plastic.

I am using 2 Sigma 14mm lenses for time-lapse photography in our earthquake test lab. They provide a view of the entire lab without fisheye distortion. The quality of the images, using Canon 450D cameras is good.

The Sigma 14mm f2.8 is a great lens. It does a good job of keeping line straight. As others have stated you need to stop down (5.6 or higher) to keep sharp focus. That's the case with most very wide angle lenses. It is difficult to focus as others as said.

My copy of this lens gives good image quality, though it does have slight barrel distortion (things near the edge of the field of view bulge out very slightly). This is typical for this wide of a lens, and isn't noticeable unless viewing something with lots of straight lines near and parallel to the...

flare is a problem if you use dxo for correction its a great lens for cloudy days as flare makes it unusable, if you can afford the canon version 2 i would buy that instead its Better than the samyang and better than nothing which is the alternative, did i mention the flare updated this as i have...

Bought this lens brand new when it first came out, using it on a Nikon F5, then the original D1. Hadn't used it much in several years, but pulled it out recently upon finally getting a FF sensor camera (D4)--still works like a champ, and built like a tank.

This is for a Canon mount. All the other reviews pretty much sum up this lens. On APS-C it crops out the ugliness of the smeared corners. I can't get a sharp pic in any corner at any aperture on FF. On APS-C it's a different story. Just use f5.6 for everything and you will be ok.

I own the Sigma 14mm F/2.8 in a Nikon mount, and it is quite fantastic on my D600. I'm surprised that Sigma no longer makes this prime, especially considering how Nikon and Canon are creating lower cost full frame cameras these days.

An older lens of this type I had was better - this suffers flare more and isn't so good in the corners at apertures wider than f4.5. Its distortion characteristics aren't as sound, either.

Definitely one of the better sigma lenses. Sigma has always been hit or miss for me. This lens is a hit. Very sharp and very wide. Barely under fisheye. oh did I mention it is very, very wide? I love it.
