I JUST UNPACKED my XL2 today!
What a BEAUTY! I so look forward to putting it to good use.

The MAJOR REASON I went with the XL2 over the Panasonic DVX-100A was expandability. I'm not just stuck with the camera as it came out of the box. It can grow and expand with me.

My question is, what are some KILLER TOYS (accessories) that you all recommend for the XL2? These don't have to be Canon parts. I'm just looking for the best add-ons and gadgets you guys have stumbled across.

Cheers!
Luke

Hmm, I'd say the best killer toy for the XL2 is the M-203 grenade launcher.

It'll mount under either the manual or the auto lenses and pretty much garuantees you a good shooting position at any media event.

Gotta agree with Dylan, mine works flawlessly
