This lens looks pretty fun, but I can't figure out if we would have too much overlap. My wife and I are both hobby type photographers, and enjoy taking pictures of our kids, the outdoors, and my wife does pics for her blog.
We have a T1i with the following lenses:
50 1.8 IS II
40 2.8 pancake
18-135 IS
Sigma 17-50 F2.8 HSM
Since we have purchased the Sigma, it has pretty much lived on the camera constantly. The richness and sharpness it has provided has been awesome. The 28 2.8 pancake looks like fun, and would be a nice walkaround, but besides weight and size, what advantage would I have?
Thanks!
