That's a wide open invitation for help... if she's serious about it, she could get some serious revenge for your CVO purchase with this hobby!

I have one lens that cost $2300!
I'm a Nikon guy, but the basics are all the same.
THis is a pretty good price for a basic telephoto with image stabilization. DO NOT PAY $299 for it!! If you go to the right side under "more buying options" if you buy it through Amazon, it is $213.

They must be getting some serious kickback from the other folks at that much of a price difference!
