Hio all,
I have ordered this lens and will be using it for birds with or without TC and also for sports and portrait when I'm not leading tours in my place.
My questions is :
Has anyone tested this with the TC2III ? Do you need to stop down at f8 to get the sharpness or at 600mm f5.6. is it sharp ? My current body is D300s and will be using the Velbon 830 carbon tripod and Manfrotto 502 video head for this combo
How about with TC1.7 ?
Advice and comments are appreciated :king:
