Thou shall not divert energy from Canon's R&D department from
DO-elements to IS-systems....:))
While we are at it, I want a 200/1.8 DO-IS that weighs less than 2kg,
with the length of a 200/2.8....there surely must be a reason why
the old 200/1.8 still has no IS-successor....;))
Hmm....a 400/4.0 divided by 2 is a 200/2.0....okay, that will
do....:
