Canon 7D AI Servo mode evaluated for BIF tracking.
Canon EF 2X II teleconverter mounted on lens. Images were shot hand held
and with IS active. When the teleconverter is installed on the
Canon EF 70-200 f/2.8L IS USM, the combination is not the sharpest
tack in the box. Much better sharpness can be obtained with the 1.4X TC.
Image #2 in series.
