Canon EOS 70D 故障排除

In SCN mode, I cannot change out of Handheld Night Scene. It is like it is stuck

Canon seems to have changed the importance to quality that it used to distinguish it. I still have an Elph 300S that is about twelve years old and a T2i which i bought in Radio Shack and both are still working fine. I'm disappointed because i bought a 70D in second hand from a seller in a famous online store and it looked like new and working fine. But, suddenly it's impossible to turn it on. I tried everything recommended with no avail because I've seen a lot of people with the same problem and Canon seems to give no importance to it and don't care about it. That has made me change to another brand that I'm considering.

Canon eos70d ISO & aperture increases automatically while changing shutter speed in manual mode. Please

I think the arrival of MILCs and success of Sony made them lose their calm and brain. These days Canon is not producing quality cameras anymore, even good lenses are becoming increasingly rare. Perhaps it’s time for Canon users to think seriously about other brands.

Problem with EOS70D: shutter stays open on first shot. It is not a lens issue as lenses have been swapped. Lens must be turned to disconnect contacts and then reconnected. The shutter completes the shot when the lens is electrically reconnected and then the camera goes back to regular shooting. A time lapse of approximately 1min will restart the error.
