I have no trouble at all focussing in low light with my Canon (450D) with Canon lenses (like my cheap and cheerful 35mm f2). But with my Sigma 18-50mm f2.8 EX DC things look a bit different. In low light, things are fine... but in really low light, it does struggle.

I find contrast focusing on Canon cameras sluggish and inaccurate under low light conditions. Phase contrast is fine.
