All right, I'm getting one. What impresses most is how sharp and contrasty it is wide open at f/2.8 without too much loss compared to stopping down. I was waiting until we could make sure this wasn't a f/2.8 lens that's really a f/4 lens for any serious use.
It makes me wonder if we are seeing the start of a new trend. Higher ISO in the camera and slower lens.
The last 3 Canon lens have been f/2.8 - and they are all quite modestly priced.
Has anyone got hold of the 24/28 f/2.8 so we can compare?
