Sigma 10-20mm F/4-5.6 [Review]

A lot of people have been asking me to do a quick review on the Sigma 10-20mm lens. First off, the build quality. The way this lens is built is perfect. It seems very solid, stable and durable. It's built with a metal lens mount, which adds to the solid feel to the lens when you hold it while it's mounted to a camera body.

At 10mm, this is one of the widest lenses on the market. This allows you to get some very wide shots, getting a lot more in the frame than other lenses. Even when zoomed into 20mm this lens is still very wide. Although the lens only has an F stop or 4 at 10mm, it's still pretty fast, and when combined with a strong tripod, produces some sharp pictures!

Here is the lens itself. As you can see, it does come with a lens hood, which is standard for all Sigma lenses. This is something Canon & Nikon should start doing, as the lens hoods is a great feature that reduces lens flare and also adds a bit of contrast to your images.

With such a wide angle lens like this, you will notice some distortion in your images. Because of this, this lens may not be ideal for shooting portrait work. But when shooting landscapes, seascapes, and skylines, it does the job perfectly. If you have PTlens (An application used to correct lens distortion) you will be able to shoot some pretty spectacular work, and if you're brave enough and know what you're doing with correcting lens distortion, you might even be able to do some portrait work with this.

The minimum focal length of this lens is 0.24 Meters, which is great. You are able to get really close to a subject, but because of how wide this lens is, your photos will not appear as close as you really were. With most new Sigma lenses, this lens also hosts an AF feature, as well as a Manual focus feature. AF is pretty standard with most cameras / lenses on today's market. The AF speed is pretty fast, not as fast as some Canon L glass lenses, but for the price of this lens, it's good enough.

Overall this lens is awesome for shooting landscapes, and could even be used for portrait work with a little knowledge! Here are some examples I've shot in the past week with this lens. I'm loving it so far!
