Canon Extender RF 2x Reviews

New posibilites!

This x2 extender has allowed me to get some really video shots and still photos with my 70-200 RF USM L lens. Also been able to do a little bit of birding. How cool is that!?

Extended Zoom

I would have given this a 5 if Canon's engineers had been able to allw the full zoom range on the RF 100-500mm f/4.5-7.1L IS USM (it can only be used within 300-500mm range). As a practical matter, it makes the 100-500 mm lens a 600-1000 mm so it does extend the reach of the zoom, but it limits cropping flexibility.
