Canon EF 200-400mm f/4L IS USM Extender 1.4x

Summary

When the Canon EF 200-400mm f/4L 1.4x was first announced it set a lot of buzz within the Canon universe and thankfully the lens doesn’t disappoint. After testing it in many environments and under many different situations around the globe I can say that I have yet to be disappointed by what this lens can produce. Optically, it is extremely sharp throughout its range, telephoto prime level sharp which isn’t something you can say about most zooms. Even with the internal extender engaged the image quality is superb. There is virtually no chromatic aberration, very little flare when shooting against the light and the vignetting is well controlled. Probably the most surprising element is how well the lens can keep focus when photographing erratic subjects as well as shooting in low light situations. In fact, it does so in a way that makes you completely forget that you are shooting with a zoom lens. From my point of view, the EF 200-400mm f/4L is the best lens I have in my bag, one that gives me the kind of flexibility and durability in the field that no other lens has ever given me and for that, it receives my highest recommendation.
