This was my first thinking once I had my camera for a while. After handling these three heavy lenses and thinking about carrying all of them plus other stuff I realized the weight would be too much, I do lots of outdoor stuff and like to carry lots of gear. This is one of the reasons I plan to stick to the L f4 zooms (might get one faster one) and get a set of fast primes.
That's a good point. I originally was going to buy the 70-200 2.8 IS, but then I held it and realised it was too heavy for me. So I ended up with the F/4 version. I still plan one 2.8 lens (Sigma 24-70 2.8) becasue it's about the same weight as my 70-200 F/4, but I am trying to avoid any lenses more then about 1.7 lbs or so. I am still worried about the wild life aspect of things, as I want to get into wild life photography, but all the lenses, but the Tokina 80-400 seem heavy (the 80-400 seems iffy though.) The one I'm eyeing is the 300 F/4 which is a heavy lens (2.6 lbs I believe), but maybe it won't be so bad considering it will almost always be on a monopod.
