I can already hear the wailing. The 50mm won't be small enough compared to the competition. Or it won't be big enough. If the 70-200 lens aimed at video can't take a TC, the cries will be heard at the corners of the Earth. Its a fixed zoom that isnt as compact as the collapsing design - this display of Canon's continued wanton malice towards its consumers, and continued compliance with the laws of physics will force many to Sony or Nikon.
I'm sure in use they'll all be quite good. I have the 24mm 1.8, which I like for is small size and macro function. But I'll have to see what this 24mm L has to offer. Still rocking my Sigma 50mm Art - no reason to upgrade that one. Maybe some good deals will be had on the external zoom 70-200s and I'll finally add one to my bag.
