EOS 5D Mark II USB cover tether broke and fell inside

Hello,

I'm a bit worried but not overly worried about this but figured I'd ask the experts.

Recently my USB Cover Tether broke on my camera and I bought a replacement.

Yesterday the replacement came in and when I tried to extract the tether from the hole it is situated in it fell in. Not ideal, but it doesn't appear to have gotten anywhere that it can damage anything on doing some testing at as many angles as I could think of.

Is the shutter or sensor in danger of being damaged by this part, and do I need to open the camera up to get it out, or should it be safe to leave in? I just can't tell from any of the videos or schematics I've seen if this cavity for the tether has uninterrupted access to the mechanics and optics of the body but I'd imagine not, since this kind of thing is something that isn't that unrealistic to happen.

Thanks in advance!

Greetings,

Given the cameras age (17 yrs old), I don't think I'd try too hard to extract that piece. It's unlikely to cause a problem but I'm not saying it couldn't or won't. I'd fit the new piece and go with it. Start saving for a new body. It's time to upgrade. 😉 A lot has changed in the last two decades.

I was concerned about the same thing with my 7D. Happily, I was able to pull out the tether completely.

I"m guessing that there's nothing mechanical or optically that would be interfered-with by it falling in.

Thanks for the reassurance, though I was actually gifted the camera for Christmas last year, so still pretty new to me! My dad has a Mk III which is already better so I can imagine that there's quite a bit of improvement, but if you think it's unlikely to cause issues I'm happy to hear it.

It doesn't seem that way from what I've seen, but I'm still pretty new to all of this so I like to check!

Well, I'm not ever going to try disassembling my DSLRs, and have not looked for internal views of them. It's just looking at where things are and where I think are places where nothing is likely to be moving inside.

Why don't you test it by using the camera in different orientations and shaking it around to see if the shutter is being interfered-with. If it is, I would be inclined to have Canon or a professional open it up. Sure wouldn't be myself doing it!

So far testing has not produced any issues, so I think I'm in the clear!
