Please excuse me if this has been discussed to death already - I'm a newbie. Almost 3 years ago I bought myself a Canon Rebel XTi for Christmas to take better pictures of my daughter. A 430EX flash, 50mm 1.8 prime lens, and 55-250mm f/4-5.6 IS Telephoto Zoom Lens later I'm looking to upgrade the camera body. I have around $1K to put into the new camera (can be persuaded to go a little higher if it's a big difference in quality). My primary subjects are my kids and my main focus is improving image quality indoors. I had some great moments last weekend in front of the camera but the images turned out grainy which was extremely disappointing. I'm not a "for hire" photographer but will take pics for friends and I want to take really good pics of my family. I'd love any and all advice you have. Thanks!
