Bokeh is not better on the f/2.8 IS L II than the f/4.0 IS L

Would you consider the added weight and expense of the EF 70-200mm f/2.8L IS II USM unnecessary?

The wider aperture is unnecessary for me, and now that the latest cameras shoot clean images at ISO 6400+I don't see why anybody needs f/2.8 to freeze subject motion.

So for me the question was "Is slightly better Bokeh wide-open worth double the price and twice the weight"

Bokeh is the same - exactly the same in fact (I tested this). You get more blur with the faster lens @f/2.8 which the slower lens cannot match - but that's something else.

For bokeh the two lenses are (as always) best wide open. So bokeh @f/4.0 is somewhat better on the f/4.0 lens than the f/2.8 lens - because its stopped down and you can see the adverse effect of the aperture blades on the bokeh.

After f/4.0 its a tie between the two.
