EOS 550D What is this piece?

Atheer — Wed, 02 Nov 2022 12:42:49 GMT

I removed the lens to clean the sensor and this piece fell of. I do not know if it fell from the lens or sensor

My camera is Canon 550D

Hello Atheer Welcome to the forums. The part that you show in the picture is most definetly from the camera body and not the lens.

I don't see anything remotely like that inside my mirror box. It looks like the contacts for the SD card, but there is not enough of them.

Agreed. I am sure it's not from the lens. Either way your camera needs to the attention of a sercice tech. Canon is unlikely to touch it - it's way out of service life.

Does the camera still function correctly? If so your cheapest option is to use it until it does not, then consider a replacement.

That looks like a part from your lens. Your lens will not work properly without that part and it is probably cheaper to buy a used lens rather than repair. Lenses often have flexible ribbon cables but they also have contact strips to keep electrical contact on the barrel as you focus or zoom in and out. Which lens or lenses do you have?

How can it possibly get past the rear element and mount? I know "weather sealing" is more of a marketing term, but it is not *that* bad. 8^)

Many consumer lenses are open at the back and it's not uncommon for broken parts to fall out.

Mike that is a huge chunk of hardware to come out of the back element of a lens! I have found a site that might be better able to answer this question: Here .

That piece may be big, but so is the opening around the rear element on these consumer lenses.

Here us a video showing disassembly of an 18-55. That part is called the "focusing brush" and can be seen at 9:40 in this video.

Wow... You appear to be spot on. It's much smaller than I thought, even given the image of the OP's hand. Well, one wonders how that came adrift! I would suspect it might be cheaper to get a replacement 18-55 (this time an STM version) than to have the lens disassembled and fixed. Given this has come out, I would guess the lens has had a serious knock at some stage, so the optics might be out too.

That brush in the original post doesn't look like it came from an 18-55. I'd be curious to know what lens or lenses the OP has.

Here are more examples of "brushes".
