Product ReviewsSigma 12-24mm f/4.5-5.6 II DG HSM Lens for Canon

A must have for affordable but sharpwide angle work on a full frame camera.

What a wonderful lens this is! My copy is sharp from f6.3 onwards and is stunning around f11-f13. Absolutely my favourite landscape lens. Funnily enough it performs best at the 12mm end, the opposite of all my other wide angle lenses. That said, it is no slouch at 24mm, just a tad softer at the edges. There is no obvious light fall off, although I have lens vignetting profile enabled in my Canon 6D. This lens is a worthy full frame replacement of my Tokina 11-16mm which I sorely missed when moving to full frame. Yes it is a bit slow, but hey who cares when you get huge real estate and superb performance. Flare is reasonably well controlled but needs to be considered when shooting towards the sun. All in all, I love this lens.!Read full review...
