Canon Lens Rear Cap for Canon EF SLR Lenses
Filed Under: Canon Cameras



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.

I use lots of lenses and have three different XX-to-EOS Lens mount adapters. To protect them I purchased this cap. It goes on the EOS end (obviously) and protects the chipset for the assisted focus feature.
When I purchased this item the total cost with shipping was under $5 so I don’t see any reason to complain about price – to me it seems a veritable bargain – I probably should have ordered an extra or two at this price!

I bought an extra one of these for modification into an erecting eyepiece, for converting Canon long telephoto lenses into spotting scopes (in particular, my 100-400mm). The project went exactly as planned, and resulted in a very useful eyepiece that fit snugly into the lens, eliminating the necessity of buying a spotting scope to match the optical quality of my 100-400mm, and eliminating a heavy spotting scope from having to be dragged along on birding trips.

Canon’s lens caps are well-designed, and provide a snug tight fit, with a minimum of effort. They work perfectly with Canon lenses, as well as with Canon compatible lenses by Tokina, Tamron and Sigma. The same can’t be said for some Tamron lens caps, which are fine on a Tamron lens, but loose on some Canon lenses. Tokina’s caps may not be as easy to grip, but might fit even tighter than Canon’s.
While functionality is not an issue, cost is. Like many photo accessories, this Canon cap is overpriced, unless you think seven dollars for a piece of plastic is not ridiculous. There are alternatives. Manufacturers in Asia, expert at copying products, sell comparable lens caps on eBay, for a for a dollar or two. The Canon cap is great, but if you can get an equivalent product much cheaper, does it really matter who’s name is on it?

What do you want? It covers the rear of lens. Nice to have a couple around so you don’t have to dig in the bag for a cap.
