2nd Lens For My Canon EOS Rebel Xs

{This post might be a bit off-topic, but I figured this is the most logical forum (as opposed to General Discussion) for it. If I figured wrong, just let me know!}

My teenage daughter has become interested in photography. She has her mother's 1980s point-and-shoot camera, which she is learning how to use and enjoying taking pictures with - mainly people, animals, and nature scenes.

But she would also like to learn how to use a DSLR camera, so I'm thinking about buying a second lens for my Canon EOS Rebel XS, which I purchased for coin photography. I don't take photos of coins everyday, so sharing the camera seems like an economical way to go.

A Canon Knowledge Base document, Specifications of the EOS Digital Rebel XS, specifies the following under "Compatible Lenses":




and it recommends a Canon EF lens mount.

Naturally, a company ought to recommend its own products, but if y'all have recommendations for any specific lens mount and/or lens for this camera, Canon or otherwise, please let me know.

I'm also interested in any recommendations regarding best place(s) to purchase these items.

Thank you!

P.S. My camera does not currently have a memory card, which I assume I will need to purchase as well. If you have any suggestions for an SD card, I'm all ears. The Canon Knowledge Base has a document titled, Estimated memory card capacities for the EOS Digital Rebel XS if that's helpful.

I found a memory card on Amazon.com that seems to fit the bill, but please let me know if not (remembering that I am quite the noob when it comes to photography).

¡Gracias de nuevo!
