Sigma 12-24mm f/4.5-5.6 II DG HSM

I recently bought my first non-Canon lens, the Sigma 12-24mm f/4.5-5.6 II DG HSM ultra-wide angle lens. Below are some of my first images, all taken on a Canon EOS 5D Mark III.

The Sigma 12-24mm lens is one of the widest rectilinear (i.e., non-fish eye) lenses on the market – considerably wider (and cheaper!) than Canon’s EF 16-35mm f/2.8L lens. I’m hoping to use it for dramatic landscape shots, although a problem is that, because of the way it is constructed, the lens doesn’t take filters or filter holders, so a bit of DIY may be required.

In the meantime, though, to get a feel for the lens, I’ve been using it around town (Tokyo and Norwich). It’s a lens that definitely requires a fair amount of practice: my results so far are pretty hit and miss, but when a shot does come off, the effect can be quite spectacular – as in the photos of the skyscrapers in Shinjuku or of Norwich Cathedral below.

In terms of the optics, I’m actually very pleased. On the internet, I’d seen images with very soft corners, but looking at my own shots, I’m actually quite impressed with the corner sharpness. Very happy so far! A great lens for a great price!
