New Canon 400mm F/2.8 Could Feature Built In 1.4x Extender
People all over the globe drooled over the built in 1.4x extender on the latest Canon 200-400mm F/4. It appears that the attention caught Canon’s eye and they could be looking to bring the feature to their next 40mm F/2.8 lens.

A new patent uncovered over on Canon Watch shows the plans for a new 400mm F/2.8 lens with the addition of a 1.4x extender. This would be big news for sports and wildlife shooters, as it would give a nice range boost and a much better quality increase over external 1.4 extenders.

The downside, of course, is that Canon tacks on quite the pretty penny when including features like this, so if a lens such as this does ever come to fruition, don’t expect it to be cheap. I can definitely see this being a highly requested feature for some though.
