Well I just HAD to have the Canon version of my old nifty-fifty (50 1.4 - arrived today from B&H). It really is the perfect lens for around the house natural light shots. Sharpness is a real challenge with a fast moving bugger since it takes ISO 1600 and f1.4-2 just to get the shot (no room for error with that DOF). Here's Luke having a little ice cream (a rare treat so he eats it in no time flat) - 20D - 50 1.4 @ f2 ISO 1600: I'm a big boy, I'll feed myself. - 20D 50 1.4 @ 1.8 ISO 1600: And here's Mom brushing his teeth just before bed - 20D 50 1.4 @ 1.8 ISO 1600: Thanks for looking; comments always welcome.
