Hi,
I have a fairly new Canon 77D (probably only taken about 1000 shots). Everything works fine when I am in one of the automatic exposure settings. As soon as I switch it to manual, it will not take a picture without me pushing the shutter button twice. I am not talking about pushing halfway and then full, I am talking about two full. I push the shutter release to half and hold it to compose the picture, press full, and the shutter comes down and never comes up again. I can walk 30 feet and press the shutter again, and I will get a picture of whatever the camera was looking at then, not what I first aimed it at.
The viewfinder and the back of the camera screen both go completely black and I can't see anything to make adjustments to the composition.
This happens on both auto and manual focus.
I have confirmed it has nothing to do with the lens (tried two, and there is no problem with them on my other camera) and I have reset the camera to factory settings without that solving the problem.
Googling has only yielded a lot of descriptions of camera functions and how to press the button halfway, which is not helpful.
Can anyone help with this? At this point I'm guessing a defective mechanism, but if there is something that will save me sending it in for repair, I would appreciate it. Thanks.
