Quote:f/5.6 at 600mm? We're looking at a front element at least the size of that from a 300/2.8. Are there any screw-in filters larger than 105mm available? (because it's going to be at least 110mm)I suspect they might use the same rounding trick as Sigma did on the 120-300 f/2.8 and 105mm filter. Anyway, for bigger lenses like this, isn't it more traditional to have either a drop in filter, or lower cost still, a gel filter on the back?
As a random thought, what is the biggest non-L lens DSLR Canon have made? Anything bigger than a 70-300 zoom?
