Q: 4. How would you say the 400 f/4 DO II compares to the 300mm f/2.8 in terms of sharpness & bokeh? Trying to decide between the two and am inclined to more reach available in the 400mm.

A: The Canon EF 400mm f/4 Do IS II USM lens is so new there are no real world reviews on it yet. It is at this time in pre-order. So there is no comparison made yet on that and the Canon 300mm f/2.8 lens, a href= http://bhpho.to/1xyjxIi. target= _blank http://bhpho.to/1xyjxIi./a In general a shorter lens can be sharper than a longer lens. And a lens with a wider f/stop usually has more bokeh effect unless it is a very wide lens.
