I just got this beautiful 100-400mm zoom L-series and I have for the moment only superlatives about him ... Price well below the market delivery "lightning" in 24 hours: thank you Amazon! Beautiful, pretty heavy, meticulously manufacturing, I have already been able to test it with my EOS 5D in my garden (birds, plane, etc.) indoors with my super Speedlite 550EX, and also on my Manfrotto tripod. You get tired pretty quickly freehand when one remains in a position to "shoot", but the result is worth it, anything not 100% perfect but excellent (we forget to office multiplier 1.4X and 2X III III. ..): normal at this price compared to fixed focal length optics of this! The IS is effective and essential without a tripod. I râté a beautiful closeup of a perfectly lit red throat because I had set the zoom button on 6.5m-oo, and the time to swap in the 1.8 m-oo, this beautiful bird had flew (he was 3-4 m me on a branch ...). Unable to find Used in good condition, so do not hesitate to invest in this beautiful zoom "for life", even if the great price / quality ratio is not within the reach of every budget.
