Summary: I take an extra Cap for either end of each of my lenses. If two lenses share the same cap size then I only take a single extra, as I don't plan on losing TWO on the road, at least not the same day... You could always go with an off brand and pay a little less, since let's face it, by all rights, this thing should be about 4 bucks, MSRP! I still haven't tried Adorama's house brand, but will probably try one of those next time if it's half the price of Canon's.
Summary: I gave it a 4 star rating because though it works as advertised, its missing one very important feature (the reason i lost it in the first place)...It needs a strap or a string so that you can attach it to the camera.
Summary: I'm not sure how much more there is to say about this lens cap. It comes packaged in a plastic bag stapled to a cardboard card. It snaps securely in place, which is a nice change from the stock cap on my Powershot S5IS. I do miss the leash, and will probably be buying an aftermarket tether soon for it. You can probably buy one for cheaper in another brand, but I decided to get the Canon so I could be sure it would fit properly on my Canon adapter tube.
Summary: The Canon 58mm lens cap fits the Canon conversion lens adapter very well and stays on well on my S5is. A complaint on the S5 is that the lens cap falls off too easily, but that is a safety precaution to not damage the lens if the camera is powered up and forgetting the cap is still on. With the LAH-DC20 adapter in place the camera is extended past the lens when powered on so a much more secure cap can be put on. This is the cap for that job!
Good but could be better (string attachment ring would be nice)

Summary: Camera: Canon S3 IS Used with 58mm adapter for camera. I do admit that a cap that locks into the threads of the 58mm adapter that I have is great and all, but is it really that much to ask for them to put a ring on the side with a string so that it can be attached to the camera in some form or fashion so that it wont get lost or put through the washer because it was still in the pocket.
Summary: I am using this on a Canon S3IS digital camera. In order to put filters, a lens hood or this lens cap on the camera you have to buy an adapter kit from Canon. The Adapter kit works fine and the cap works fine but using them both is inconvenient. The adapter kit comes with a lens hood. The lens hood does not have the threaded ring to accept attachments. So it you use the lens hood you have to remove it to use this, or any lens cap. I now rarely use the lens hood.
