What would be the best considered site for photo storage? I see a number of people using Flicker yet I also see many using Photobucket. I am new to this and very naive in these issues.
Second question: I am seriously looking for a 70-200mm lens and would like some experiences on the new Sigma 70-200 APO with OS compared to the Canon 70-200 IS F2.8. Prices are a 'no comparison' but I am interested in performance.
