Thanks for the 600mm shots. I'm looking into the Tamron 150-600 G2 as well. Pricey, but it's down to that or sigma's 100-400. For a couple hundred more I might as well go for the extra reach. 600mm and a boat race would yield some amazing shots! Course 400 wouldn't be bad either...
Anyway, I still have time to decide as I don't currently have the funds for any kind of new glass. BTW, that 70-200 you picked up I bought that lens last year. Great lens! Stupid sharp on my 80D and I never MAFd it! As it happens 200mm is about perfect for NHRA events, if not a little long at times. Of which I'll be attending and posting subsequent photos in just about 2 weeks!!!!!
