I am going to be traveling a lot this summer and I am looking for a good telephoto lens, I have narrowed it down to these two:
Canon EF 70-300mm f/4.5-5.6 DO IS USM
vs.
Canon EF 70-200mm f/2.8L IS USM
I like the 70-300 for the size but I know the 70-200 will be better...so which one do you think I should get?
I think its going to come down to your "travel constraint" issues. I think that from an optical perspective, the 70-200 f/2.8 (with 1.4x when necessary) will beat the 70-300 DO IS (...it definitely stomps my 75-300 IS predecessor...) but there is a pretty hefty weight difference between the two.
Two years ago, I carried my 75-300 IS and a WA lens and body on a 20+ mile hike on the lowlands Inca Trail to Macchu Piccu ... that was a pretty reasonable upper limit. OTOH, when it comes to urban cities, I generally like to lighten up to just a point-n-shoot in a fanny pack.
I'll be packing soon for a trip to Tanzania, and we have a 33lb weight limit. Nevertheless, my 70-200 2.8 IS w/1.4x will be going, even if I'll only be able to pack a thong for clothing. Everything's trade-offs. FWIW, I did think long & hard about the 100-400 IS lens for this trip, but decided to trade some focal length for low light capability.
