Front lens cap for 350d

[ConfusedChicca]

What size thread lens cap do I need? Lost my front lens cap (no idea how) and need another ASAP.

what lens is it? The lens itself should have a size on it, probably something along the lines of 55mm or something

It is usually written on the trim around the front glass of the lens.

The kit lens from my 20D is 58mm

Apparently its 58mm, I've managed to track one down on ebay, and the guy also sells UV filters which is very handy for me!
Thanks for replying.
