My wife is pregnant and I want to be able to capture really nice, sharp photos while inside of the baby once it arrives.

Here's what I currently have:
  • Canon 7D
  • Canon Canon EF 70-300mm f/4-5.6 IS USM (I want to upgrade to Canon EF 70-300mm f/4-5.6L IS USM)
  • Canon 24-105L f/4
  • Canon 50 1.8 II
  • Canon EF-S 10-22


The 50 1.8 is nice, but I don't like being stuck at 50 or in my case ~70 while inside. I am interested in the lens in the title due to the flexibility in range and that it's at f/2.8 for inside use and low DoF.

Does anyone use this lens for what I want to use it for? If so, can you post some examples? I'm hoping to get the lens for less than $1000 if possible.

Thanks and Happy Thanksgiving!
