I'm planning to get the 300mm f/2.8 L II next and have saved up for the most part. I'm confused whether I would need the 100-400 after I do get the 300. That said, should I sell the 100-400, I might just be able to give myself an early Christmas present or else I have to wait a few months.
All you guys who have used the 300, have you needed the 100-400 after getting the 300 f/2.8 L II? If so, why?
They differ in portability, so the question is how would would you get close to a portable solution to 400mm. A couple possible options are
1. selling your 70-200 f/4 and your 100-400 for a 70-300L, which is compact and portable but you lose some range.
2. selling your 70-200 f/4 and your 100-400 and using a 2x III with your 70-200L, but this is a heavier, bulkier solution.
