Instead of upgrading my Canon 100-400 f4-5.6 version I
with the new version II, I purchased the new Sigma 150-600mm
f/5-6.3 DG OS HSM Contemporary Lens which has received highly
positive
reviews
.
Gear: Sigma 150-600 set to 600mm atop my Canon 1D Mark IV with Canon 1.4x III, hence
a calculated 840mm, but with the 1.25x crop of the
camera body, the equivalent focal length is 1050mm. All shots
were taken hand-held or with a monopod tucked into my belt. The selected
pictures were culled from ~1000 shots taken within a 2 hr period- this was
a particularly lucky day with very active kites and the hawk.
