T7i is 7 years old and having issues, should I get it fixed, or upgrade?

Lets talk about your general usage of lenses....
Do you swap them quite frequently? Are the lenses noticeably older than the camera? Is the issue on all lenses or just a specific one?

Here is the deal, the camera has pins that touch the lens contacts. Either side of the connection can be scuffed/brassed/ or just dirty.
The first simple approach would be to use a small swab and a touch of rubbing alcohol that dries instantly and try to clean the dirt off the pins and contacts. Some people say an eraser helps but i feel that can actually ad abrasion to the brass so be careful. You can watch some youtube on cleaning. You should be able to identify if its a lens or the camera deepening on if it impacts all lenses or not. You probably do not need to change gear, a cleaning is the place to start.


Neither of them should be having communication problems with average use after 7 years in my opinion. Cross my fingers i have not seen this issue even on my old gear yet. Maybe you got some bad luck or there was wear an tear on the mount, its hard to say. Considering sending in for repair will cost a few hundred bucks, I can see the idea of upgrading as the better investment. If you think the camera body is the culprit that is. Also, at that point I would step up from the rebel line and get a more featured filled camera from the mid tier bodies while you are at it.
