I got myself a nice new toy this morning, a Canon EF 24-70 f2.8 L USM lens. It's beautiful. Up to now I've bought EF-S lenses and they served my needs well but with my wedding coming up and a friends wedding before that where I have to take photos I thought I'd make the leap into pro lenses. My walk around lenses were good but when i zoomed in the aperture would go up and they never worked well in low light. I've played around a little this afternoon and have been impressed so far. We had to go to a wedding fair this afternoon so my opportunities to test the lens have been limited but hopefully I'll get out tomorrow and put it through it's paces.
