I am having trouble deciding between the following:
1.Sigma AF 70-200mm f/2.8 EX HSM DG
2. Sigma AF 100-300mm f/4 EX HSM APO
3. Canon EF 70-200mm f/2.8 USM L
4. Sigma AF 50-500mm f/4-6.3 EX HSM APO (Bigma)
I will be purchasing a 1.4X TC at some point also.
I am looking for a fast, sharp lens for shooting some surfing, mountain biking, kite surfing, and a lot of shots from a boat of the shore line (houses and beaches) I would just like some help from people with first hand experience. I've seen all the archieves of pictures and read tons of reviews but I'm still undecided. Please help.
