Greetings,
I picked up this Canon EF lens and am trying to purchase a cap and rear cap for it.
Usually a lens has that Greek symbol showing what size it is. Am I missing it?
Also, where might be the best place to search for the caps? B&H? KEH? Do they sell kits with front and back caps or do you have to buy them individually?
Any help is greatly appreciated.

Google the manual for the lens and it will tell you the front cap filter size. Then buy one that size, as well as a rear lens cap for that particular mount.
 
Thanks, that's a great idea.

Or you can measure it with a ruler. It's the inner diameter of the front of the lens (where you screw in filters). Typically a small Canon lens tended to be 55mm, but if you can look it up or measure it, there's no point in guessing.
 
I've only seen them sold individually. Any larger shop, online or local, should have them.
