Will the new Canon ones hold onto a thin filter? I use a thin/slim filter on the 16-35 and have only been able to use a press fit cap.

On another topic what glue will hold one of those plastic elastic cap keepers onto a cap? I tried super glue and it popped off a day later...

Superglue is only good for gluing fingers together.

I haven't tried this, but I would dab a little PVC cement or model glue on there.

Here's another current thread on centre-pinch caps,

Which eBay store did you get the center pinch caps with Canon logo?

quick ebay search found this

http://www.ebay.com/itm/77mm-Center-Pinch-Front-Lens-Cap-for-Canon-Lens-Filter-/190779334264?pt=LH_DefaultDomain_0&hash=item2c6b559e78

I went to a local camera show/swap meet a few weeks ago. A couple of the vendors had boxes of Canon lens caps on the counter, including the center-pich caps. The were $3 each, or two for $5.

I wonder when more sizes of the official Canon center-pinchers will be widely available.

If the fleabay pinch caps came on Canon lenses I'd of never noticed any difference, they'll work fine and have the Canon logo on the front!

I have a dozen or so Tamron caps. They are a bit bulkier than the Canon, but good for hooded lenses

I order mine off eBay and got 7 for a descent price and was able to tell them what sizes I needed and that's what I got with the Canon logo on them

B&H has the OEM Canon pinch style caps, but in only 2 sizes that appear to only fit mirrorless EF-M lenses:

"The Canon E-43 Lens Cap for 43mm Diameter EF-M Lens is a protective cap that fits on the front end of EF-M lenses with a filter diameter of 43mm. It works with the EF-M 22mm f/2 STM lens. The EF-M lenses are compatible with the EOS-M mirrorless digital camera"

The eBay ones are likely counterfeit, but if they work, and Canon refuses to make them...

I notice the other day when I finally got around to using the ones I got off eBay that they had a small hole for a lanyard just like a thumb drive. Not the I used it.

I ended up picking up the pro master versions at the local camera shop. 6 bucks or so. They work great.

I too use the pro master ones , cheap and work well!

I use the Bower brand from B&H. I think I have 10 of them and they all work fine but the one I have on the slim filter on my 17-40 does have a propensity to fall off but I can't really blame that on the cap.

Here, for example, is the 77mm version:

You need epoxy to hold onto the plastic cap. Why not just put it in your pocket?
