wickerprints, that's an interesting point you've made.


I've used my 70-200 f/2.8 at 70 mm, 200 mm, everything in between, from f/2.8 up to f/11. These are my anticipated shooting conditions, and I would think anyone using this lens would never be limited by one f stop or distance, etc.


So, I'm just curious what is the big deal for anyone to find precise focus for such a lens.
