I bet 90% of the time I don't miss the 2.8. Especially since it is that much lighter. I have used the 2.8 IS mark 1, but not any of the other third part lenses.
Maybe it has changed, but i'm pretty sure the f4 non-IS is NOT weather sealed? I don't have a 1D so my body isn't weather sealed so I still baby everything in the rain.
It was my first L lens and i've been happy with it. I can't go back to variable aperture lenses!
