Hi all.

Looking at getting a longer lens, say a Canon L series 70-200 f4 for landscapes, I'd like something longer but with a crook back I'm always thinking weight vs anything else.

So my question is.......using say the L 70-200 normally with the rare use of an L 2X extender vs say a 100-400 with the added weight all of the time.


What's best?


Cheers,

Mark.
