What We Like
+Constant f/2.8 aperture throughout entire zoom range – first and only 100-400mm equivalent lens with this brightness
+Exceptional 5-axis Sync IS providing up to 7 stops of stabilization for handheld telephoto shooting
+Remarkably lightweight at 1,075g without tripod adapter, with excellent balance and portable design
+Excellent image quality with minimal chromatic aberration, distortion, and edge-to-edge clarity
+Versatile 0.78m minimum focusing distance enables macro photography at 0.5x magnification without teleconverter
+High-speed autofocus supporting 50 fps continuous tracking for wildlife and action photography
Worth Knowing
Premium pricing at $3,699 USD, significantly higher than competing telephoto options
Light fall-off in corners at maximum f/2.8 aperture requires stopping down 2+ stops to fully eliminate
Bokeh quality becomes fussy in some backlit scenarios, with polygonal edges when stopped down
Macro performance with dedicated macro lenses falls noticeably short compared to dedicated macro optics
