My Canon 28mm F1.8 focus ring rubber has turned sticky. Where is the best place to order a replacement in the US? I think the part number is ya2-2235-0000.
Do they just roll on or is there an adhesive?

I don't know about the 28 1.8, but I know on many other lenses they just slide on and off with a little effort (no adhesive.)

When I took a lens in for repair at Midwest Camera Repair, they replaced the rubber grip as well for an additional five bucks. My guess is that they would sell you one mail order as well. I think you can find them for a lot of lenses on ebay, but no guarantees that it will be a genuine Canon piece of rubber, if that matters to you. A third party one, if they make them for this lens, will probably have a little bit different feel and/or surface texture.

Canon sells them, you can sometimes buy them on ebay, lots of places will get them for you, but you might pay more.

They are basically a big rubber band, you can stretch them to get them off and reverse the process to install a new one.

Awesome. I guess I'll try Canon directly. (or try and find someone else who'll sell me just the ring)

Midwest wants me to send the lens back for them to put it on for $130. I'd rather buy and install it, it's just a fancy rubber band. I don't blame Midwest for having a minimum price for handling it, but I don't need that much hand holding...

Lots of people do it themselves, its easy and just takes a minute. I've removed and reinstalled the bands many times when I needed to open up a lens to clean it. My Sigma 600mm mirror lens has a band about 4 inches wide, that takes more time and effort to get on and off.

The Canon parts department at 866-481-2569 took my order for $26 and change shipped. Yay!
Lensauthority would have sold me one if they'd had happened to have them in stock.

FYI: For anyone trying this - you have to disassemble part of the lens!

For this lens, it does NOT take just a minute.
The original ring was rubber coated hard plastic. This coating has turned sticky. The new replacement omits the coating (yay!).
It might be that it could be removed if you could use a cleaner that doesn't get in the lens, or if you pull the ring and clean it separately to be safe.

Replacing it required removing the lens mount and circuit board, 3 flat flex connectors from to get those out, then the middle lens barrel section. The optics section didn't need to be touched. There is a small metal ring that needs to be moved to the new focus ring. You'll need a couple of small screw drivers and tweezers to get the job done. It takes about 45 minutes if you're slow and keep referring to the one youtube video on the lens. Delicate but not hard work. I spent the most time searching through my small Phillips(- and like) screw drivers to find good matches as the screws are small but firmly seated and I didn't want to strip any. I suspect at least the mount screws may be one of the cross type heads that aren't actually phillips, but I had a driver in my collection that exactly matched.

I did my 85L II..

bought directly from canon..
it was about $15...I forget the price

if you have part number..talk to a person.
they were very nice and helpful..

someone posted the part number but I also looked it up somewhere..
haha.. I am not febble minded.. just cant remember the details

the 85L had rubber already part of a shell that came off with 3 / 4 screws..
clever part replacement...took 5 mins total and a small phillips..

I sold the lens later but it looked new..

not sure if yours is similar..
plastic shell with rubber glued on...

call canon first maybe?

good luck

There are indeed a few that have a coated ring rather than a band. Fortunately only a few.


All the screw heads in Camera lenses that look like Phillips are JIS (Japanese Industrial Standard). Don't use Phillips drivers, they are designed to cam out, and can ruin the heads of hard to remove screws. JIS drivers do not cam out. Good ones are a bit expensive, but nothing like the cost of dealing with a screw that can't be removed because the head is ruined.

Yep, that sounds right. I searched through my pile of small screw drivers that came in kits until I found one that matched exactly once I saw it wasn't a phillips match.

TommyLee - Yes, the folks at Canon were very helpful. The fiddly bit with the 28mm was the limited access to the flat flex electrical connectors. The lens mount is in the way when you remove and replace them, so much so that you need tweezers for one.
