Thats the nice thing about my setup for your parents, they wont NEED to borrow anything.
There is a Zoom Lens, a Portrait lens, and an everyday lens, as well as a Flash.
Anywhoo.. Im done whoring my shit out..
If you are shopping for them, then shop for them and THIER needs, IMHO. What does your mom want out of camera? You obviously want your glass to work on thier camera, so you need to get them somethign that uses the AF-S motors (i assume thats what you have)
Do they really want a big DSLR?
Or would they want something a bit more portable like a Panasonic Lumix G1, where they wont have to worry about lens and what not.. (this camera has some REALLY great reviews on all teh photography webites i read, as well as the magazines and was rated as the #1 non full DSLR camera last year) Its the P&S that photographers use, when they dont have their gear with them.. (yah like that ever happens)
