Build and handling
The lens is compact for its specification, but is still chunky enough to suit a range of EOS bodies up to the EOS-1D and 1Ds. The focus ring is smooth and precise, with positive feedback thanks to its direct connection to the lens barrel. Although it is useful for manual override, the ring’s central position means it can be knocked when accessing the zoom ring.
It seems a little basic for a branded professional lens to have an extending zoom barrel, but it is understandable for a lens of this size and looks solid when extended.
