    After recieving this lens in July and mounted it on a Canon EOS 1DC, I’ve got the ultimate tool (in my opinion) for wildlife photo and video. I am studying behavior of primarily deer in Scandinavia with focus on red deer and moose. I use 4K video (with Canon-Log) as the basic documentation. From that I can retrieve resonably good photos by framegrabbing (up to A3 (A3+)). Videos are downscaled to 1920x1080p.
    The shapeness of this lens is the best I’ve ever seen from a zoom lens. It produce very good contrast and the dynamic range is OK.
    It’s a very versatil lens to work with and using the extender is straight forward and fast. There is basically no decrese in picture quality with this internal extender. The effective focal range is very large and you can add on even external extenders and get a tremendous tele effect.
    I have also used this lens on a EOS 5D MkIII (not 4K) and on a EOS 7D (in order to use the 1,6X crop factor).

    Since I very often have to work in low light environment I would love to have an 2.8 aperture, but that would be a tremendous big and heavy lens. It is heavy enough as it is. There is always some compromises in every lens.

    For wildlife documentation I find this the best you could get today, and I give it 5 stars.
