WTB: Sigma Rear Lens Cap for Canon Rebel XT

[wrx2k4blue]

Looking to buy a rear lens cap for my Sigma 70-300mm f3.5-5.6 lens. I'm not sure if just ANY rear lens cap would work, but I have a Canon Rebel XT with the Sigma lens. So, the rear lens cap needs to fit!

Check www.keh.com. They have lens caps.

Any rear lens cap for an EF mount lens will work fine, if you have any local shops I'd call them up as the shipping will probably cost as much as, if not more, than the cap itself.
