A quick test with the new Canon 2X III

February 08, 2011  •  Leave a Comment
First quick test with the Canon 2X III mounted on a 300mm f/2.8L

Context: photographing my good friend the maple fox(1).
              On tripod and using a trigger, IS on, ISO 100 with the 1D MK IV
              2 exposures demonstrated here: f/5.6 & f/7.1
              focus had been made right under the eyes and righ in the center of the fox nose

Full frame image at f/5.6, iso 100

Full frame image at f/7.1 iso 100
Crop 100% f/5.6, iso 100
Crop 100% f/7.1, iso 100

At f5.6, the focus zone is pretty short and we do not see much in focus other than some surface hair. I cannot say it is real sharp.


f/6.3 is a little better.

But at f/7.1, the zone in focus is larger and allows to observe the sharpness of the shot. Almost all the
hair is sharply in focus.

The fox eye not being in the focus zone is a little blur…normal.

As for the speed of focus, it is similar to the version II…not fast and this make me conclude that the kit
cannot replace a 600mm f/4 for birding or wildlife.

I do not have my old 2X II anymore to compare head to head but I remember the shots and they were certainly not as sharp as the ones taken with the new version III.

I was astonished by the sharpness or, if you prefer, the lack of disturbance created by the extender.

This new 2X III seems to be a real killer and usable for sharp shots

I will do some more test next weekend with a different and more revealing target.

Best of light !
