Last week I rented the Canon 2x extender from the folks at Lumoid with the goal to capture some Bald Eagles on the Skagit River in WA state. I combined the 2x extender with my 70-200 f/2.8 to create a 140-400 f/5.6 lens(more about the switch to f5/.6 in a moment). The eagles were few and far but I still had fun using the lens. Watch the video and review the chart below for compatible lenses.Lenses Compatible with Canon 2x III Extender -Notice that when using this extender your maximum aperture is halved. A f/2.8 becomes f/5.6.
