Let camera sit idle and wait 2 minutes view finder clears up. Suspect the shutter is sticking. If i turn the shooting mode knob the problem corrects itself.</P> Fri, 16 Dec 2016 00:56:32 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/70d-Viewfinder-blanks-out-when-turned-on-all-shooting-mode/m-p/194899#M35227 elephant316 2016-12-16T00:56:32Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/70d-Viewfinder-blanks-out-when-turned-on-all-shooting-mode/m-p/194909#M35228 <P>See if you have the mirror up. &nbsp;This could just be from being in live view mode, or from having set a really long shutter set. Or if mirror is in lockup mode. &nbsp;Is the camera taking a photo?</P> Fri, 16 Dec 2016 02:20:47 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/70d-Viewfinder-blanks-out-when-turned-on-all-shooting-mode/m-p/194909#M35228 ScottyP 2016-12-16T02:20:47Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/70d-Viewfinder-blanks-out-when-turned-on-all-shooting-mode/m-p/194917#M35229 <P>Movie mode.</P> Fri, 16 Dec 2016 03:30:40 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/70d-Viewfinder-blanks-out-when-turned-on-all-shooting-mode/m-p/194917#M35229 Waddizzle 2016-12-16T03:30:40Z
