LensTip has completed their review of the Canon EF 100-400mm f/4.5-5.6L IS II lens. As if we needed more reasons to buy this lens!
I think those who were waiting patiently for the Canon EF 100–400 mm f/4.5–5.6L IS II USM won’t be disappointed. Its predecessor was optically very good but the new lens is better in every single category. The evenness of performance, no matter what focal length you use and what place of frame you take into account, is truly impressive. The lens remains sharp even on the edge of full frame and doesn’t have any resolution slip-ups. If you add to that the much-improved stabilization, a huge step forward when compared to the older model, you get practically a lens as close to perfection as it is only possible; its flaws, connected to vignetting and flares, aren’t anything serious.
