I'm tired of poor results from my antiquated 70-300 lens I've had for years. I'm going to throw it on Ebay for giggles and upgrade to something much, much better.
My problem is deciding which lens to go with. I've read fabulous things on this and other forums about the 70-200L ( both 4 and 2.8 ). However, I have a 28-135 IS and just feel the two lenses would have too much overlap to justify the price. I love the 28-135, and it's my "go-to" lens more often than not. It small size and weight would still allow it to get more daily use than a 70-200L.
I'm going to be using the new lens for things like professional baseball games, my son's t-ball and soccer, and wildlife photography. The 100-400L is probably the top of my list, but the size...wow. It's a big lens. Probably too big. The last thing I need is to be at my son's soccer game and be mistaken for someone who knows what they're doing. It would be a bit hard to explain to parents that I'm really not a good photographer when I'm shooting with equipment like that.
Anyway, I'm open to any suggestions as to a replacement for my 70-300. What would you go with if it were your purchase to make?
