Canon EOS-REBEL-K2 Film Camera

you must read the used description. Some seller have 2 lenses coming with the camera some will sell the body only. Always click on the USED link and read what you buy when it comes to used.

There is a wireless remote like wireless shutter for this series of cameras and i'm sure you can find it on amazon. Search for: Canon Rebel K2 remote.

Yes, your T3i can use EF-s and EF type lenses. This K2 comes with a EF type lens, so it can be used on your T3i. However, if you have an EF-s lens on your T3i (usual kind) that newer EF-s lens cannot be used on the K2 camera. Hope this makes sense for you.
