Conclusion: A necessary evil... and a godsend...
Review: I always take an extra one of these (and all my lens/body caps) with me wherever I go just in case I lose one on the road. You can of course get an off-brand cap for a little bit cheaper, but they are sometimes harder to find for some reason. You can find Adorama's version by looking for "Adorama Rear Lens Cap for Canon EOS Lens Mount." (including the period ('.') symbol). But I'm sure a lot of people want to stay in house to ensure that their very expensive lens is very protected. However, I can't truly speak to the off-brand lens caps because I don't have any. All I have are couple Bower caps that came with some of their lens filters, which aren't as sturdy as Canon's. So I think for many the branded caps are a necessary evil (price-wise) and a godsend (functionally). There is just one gripe I have in particular with the rear lens cap: it is very loosely attached. That is, it stops threading after just a slight turn, and thus comes off almost as easily. I know that this is a result of the lens design, but I would think that canon would have designed a simple system of ensuring that your rear lens cap will stay on even if bumped ever so slightly, like indentations on the lens joint that would be filled by plastic bumps on the cap and thus not affect the lens/camera joint.

Conclusion: rear lens cap rip-off
Review: again canon seems to like to charge a little more for their plastic. no need to pay 6-10 bucks. just go get an off brand rear lens cap. sure it doesn't say canon on it, but I am sure it will protect your rear lens just the same.

Conclusion: Fit perfectly
Review: Needed this cap for months. Bought it and works/fits perfectly with my Canon EOS 20D and its lenses.

Conclusion: You gotta have protection
Review: The Canon rear lens cap is included with the purchase of your EF lens, extension tubes, and tele-extenders. If you happen to lose the lens cap, you need a new one. This protects the rear elements from damage while your lens tele-extenders, or extension tubes are off the camera. To save some money, look for an off brand version at a local camera shop. There are no special parts to this cap. Don't risk damage that will end up costing more than a replacement cap.
PROS:
Protects your equipment
CONS:
Expensive for a piece of plastic (but you gotta have protection.)
