EOS 80D Lens stuck

[usdharris]

I have no idea how a student did this, but the EOS 80D has a EF 70-200 lens installed and it will not detach. The lens release button depresses normally, it seems anyway, the lens has a tiny free movement, but it will not turn for removal. The camera also does not recognize the lens or any of the functions fail to operate. I'm sensing it got put on wrong, somehow. Is there a trick or process I can perform to get it reseated properly?

Thanks

If you cannot free it by turning counterclockwise (looking down lens to camera) I would recommend you send it to Canon.

I only bring this up because I got bit by this, but Nikon and Canon's turn in opposite directions to remove the lens.

EF user since 1987, so now it is just by muscle memory. Your post made me check. Yes, CCW looking down lens towards camera to remove. 😃

I said what I did in case the teacher is a Nikon guy.

Greetings, usdharris

I'm sorry to hear that the lens is stuck on the EOS 80D camera to where it cannot be removed. We do not recommend applying too much force to remove the lens. If the lens release button on the camera is unable to be pushed down all the way then we would suggest to send the camera and lens to our service facility where a technician can work on separating the two units.

Did you turn off the camera when tried to remove the lens. Try taking some photos with it on your 30D and make sure the lens is functioning properly, autofocus etc. and then try. You could also try changing the f-stop to see if that helps.

Greetings,

Sadly, the camera's power state does not affect one's ability to mount or unmount a lens.  Mount and unmounting are a physical action.  The OP stated the body is not communicating with the lens so taking a picture is not possible, nor would it change his situation.  Since the lens is the real investment here, I agree... I'd send it in to Canon.  It might be helpful for them to inspect the camera and mount once the pieces are separated.  

@usdharris..  hope you find a solution.

If you are in fact turning it the correct direction 🤔 it needs to go to Canon service.
