To whom it concerns I have this camera and need to replace the focus screen.  Do you have the model number or link.  I see several but I do not see where they are comparable.  Thank you for your help

Actually, mine is also my focus screen that has a scratch on it. and mine shows up on my photos as well. I can clearly see the scratch on the focus screen as well as someone who has helped me fix my focus screen.

As shown in Waddizzle's post, it is physically impossible for a scratch on the focusing screen to show up in your images. The focusing screen is blocked by the mirror when recording an image.

If, as Waddizzle asks, if you are in Live View and viewing the image on the LCD then you have a hair, thread or scratch on your sensor.

The sensor does not have lines, dots or arrows on it.

The LCD does not have lines, dots or arrows on it, but the camera can display various icons on the LCD when in Live View.

This is incorrect. The focusing screen is in fact replaceable. For my Canon Rebel T7, it uses the "Canon CY3-1833 Focusing Screen" and it is in fact user replaceable. I know this is an old thread, but figured I would chime in as your response is not accurate for all the Rebel series.

Thank you! The one that my dad's friend was trying to replace mine with did not work. I'm going to see if I can find this one.

“ This is incorrect. The focusing screen is in fact replaceable. For my Canon Rebel T7, it uses the "Canon CY3-1833 Focusing Screen" and it is in fact user replaceable.”

The focusing screen is not part of the light path to the image sensor.  You have entirely missed the point in more ways than one.  

First.  If you can see a scratch in the viewfinder that also shows up on images, then the focusing screen is not the issue.  The problem is the lens because it’s the only common denominator.  

If you are using Live View, then the issue is either the sensor or the lens.  Small debris or scratches inside the lens are generally too unfocused to be seen clearly.

Second.  Just because a spare part is available for sale doesn’t automatically mean that the part is “user replaceable.”  The phrase “user replaceable” only applies when no tools are required to effect the repair.  

For example, the camera battery is user replaceable.  The screen might be “you replaceable,” but most people cannot.  

The user replaceable screens from Canon include a handling tool.  Your replacement does not.

" ... it is in fact user replaceable. I know this is an old thread, but figured I would chime in as your response is not accurate for all the Rebel series."

Yes it is an old thread but my fellow responders are correct. Any part on any camera is replaceable. Some are meant to be user replaceable but the focus screen is a part that most would not deem as user replaceable.

I have done it several times and I have also done it on my 1 Series cameras which is far easier than a Rebel. I am not sure but I think all Rebels are the same not simply the T7.

User-replaceable components, like the battery, are those that users can easily swap out with minimal effort and no tools required. On the other hand, non-user-replaceable components require specialized tools or technical expertise to replace. 

You're welcome to do whatever you want to your equipment! Head to https://canon.us/repair for all your repair options, including information on parts availability. If Canon USA still repairs your Canon gear, we'll happily restore it to factory specifications.

"User-replaceable components, ..."

It does fall on one's own definition of the term. IMHO, to the average person would not deem this as a user-replaceable part. Most I am sure don't even know what it is or that it even exists. All the ones I ever did came with a special tweezer to complete the task.

No, you have missed it completely. I just took my camera to someone local with the information that JSPhotoRI gave me and the camera repair person said on my camera it is exactly the part that needed replaced and is doing it for me. So kindly stop acting like you know everything, as I now believe you do not know anything. My camera repair man also said you don't know everything and that you are not entirely correct yourself.

"My camera repair man also said you don't know everything and that you are not entirely correct yourself."

Well, I certainly have been a critic of Mr. Waddizzle but I can assure you on this he is way more correct than not. If your repair tech said differently then you need to find a different guy because he knows little about cameras.

I too would like to know where these lines and arrows are.
