So maligned even before its release, this objective was indeed surprising: accommodate within a 70-300 L series usually reserved for amateurs while maintaining its slippery opening it as rare in this category, it was a risky bet Yes ... but suddenly this objective benefited from all the knowledge of Canon and its latest technological advantages: It remains surprisingly compact and very well finished externally. Its handling is fun. His focus quickly and formidable point accuracy. The stabilization is very effective +++ The results are actually worthy of the finest telephoto zoom lenses of the mark (at the first shots, we understood that it was a good investment). For a relatively contained price is finally an objective capable of competing with the elite of the Canon white. Despite its limited opening, the background blur are really beautiful. Overall a very good versatile and relatively compact with a remarkable Piqué goal. I regret (besides its limited opening and the "weighting" of -inabordable- foot necklace), the fragility of the internal drive me already won two passages SAV (fault my copy?). Fortunately repair is fast via barrel (1-2 weeks).
