If you pre-focus as advised, then no problem, the 70-300G would serve your purpose... note that the 70-200G is twice the weight of the 70-300G. Also twice the price when new. BUT the 70-300G second hand is quite a a steal at $900+. Do look out for it on the Buy & Sell forum. Worth the money. It's an excellent telephoto for travel, basically good at everything but not stellar... I love the colour and the sharpness. Plus it's quiet and light (relatively speaking).
