Thank you for your reply ham;

What's everyone's opinion on which lens is better for the topic I started with? The thread highly recommended Canon EF-S 17-55mm f/2.8 IS USM or the Tamron SP 24-70mm F/2.8 Di VC USD. The lens with either be on the 7D or the 60D and it will be used for indoors shots of my newborn, and family portraits.

Thank you all once again. This thread has been a lot of fun and very informative.
