Canon 200-400mm First Usage: Bighorn Sheep, Sampler

See previous notes on the EF 200-400mm f/4L IS USM Lens with Internal 1.4x Extender.

Written at 10,500' up in the mountains. My analysis of the fine points of image quality have to wait for my home system on which I am “dialed”.

I’ll be writing up field usage notes in my review of the Canon 200-400mm when I return home. So far I am very favorably impressed with the Canon 200-400mm. The built-in teleconverter is just awesome in its ease of use, as is the core 200-400mm zoom range (the 1.4X applies to whatever focal length is used).

Image below was at 560mm at f/5.6 (wide open) and had about 1/3 of the frame cropped at left and top. These sheep have a certain comfort zone; staying near ones’s vehicle helps, but they generally want to maintain a buffer of 150 feet or so. With that buffer, they just keep grazing with little concern other than the occassional “checkup” on the observer.

October is never warm at this elevation but last week’s snowstorm cooled things down and it was dropping below freezing before the sunset.

Contrast seems to be very high wide open.

I shot a variety of bokeh shots and I’ll be presenting some very interesting variants at various focal lengths and apertures.
