This is true. I thinkasachoice for sports the 70-200m F2.8L would be best, I would prefer the IS version though.


The 100-400mm F4.5-5.6L is in the mix though. If it could be in the mix of possibles, it looked to me so could the 70-300mm. I think the compact 70-300mm might be a very good lens to take to Disneyland or on safari. Personally though, if I didn't have a suitable lens alreadyand were going on a real Safari that I had paid thousands of dollars to go on, I wouldn't take any of these lenses. I am thinking lensrental.com for that one.
