6D autofocus is a revolution

Yes, thats true, but the second photo of the far off squirrel was really dark amongst the trees, thats why the camera went to ISO12800. The other squirrel photos I could have taken with the 40D, I have lots of better squirrel photos taken with the 40D. The ones that really impress me are the birds amongst the twigs, thats difficult, especially with a teleconverter slowing down the lens.
