Does the built-in 1.4x extender make the lens 280 - 560mm or is the extender to get the 200-400? Thanks.

The lens is a 200-400 is a 200-400 is a 200-400 and will always be a 200-400. It can not change its physical focal length after being made. The 1.4x gives it the appearent AOV of a 280-560.

A 1.4x Extender simply multiplies the effective lens focal length by 1.4x.

Or to put it more familiar terms: The [effective] focal range of the lens/extender combination is 280-560 mm. (I say this with no intent to denigrate Ernie's often-expressed preference for AOV as the figure of measure. It just isn't the way most users are programmed to see it.)
