I would like to give you a detailed explanation of the shutter issue during the real-time scenario of the Canon 7D camera.
Analysis and sharing:
In real-time scenario, the shutter is always open, so the shutter speed at that time is actually the speed of CMOS instant reading, and the shutter sound is also simulated. Of course, no viewfinder shutter is refreshing.
The official explanation is as follows. This is a normal phenomenon and is closely related to the design principle of a live video camera.
EOS 7D real-time display the mute shooting uses Canon's unique electronic front curtain shutter, and uses the electronic shutter inside the CMOS image sensor to implement the action of the front curtain shutter.
Because the mechanical front curtain shutter does not act, so until the end of the exposure (after the curtain shutter falls instantly), there will be no sound and vibration produced by the shutter drive.
Therefore, a good effect can be achieved if you do not want to make a shutter sound or want to avoid jitter when using a low-speed shutter.
The electronic front curtain shutter is an advanced technology developed based on the CMOS sensor and shutter unit developed by Canon.
All right, the above information is the detailed analysis of the shutter issue of the Canon 7D camera in real time for photography enthusiasts. You can see all the photography enthusiasts here, I believe that you are now very clear about the issue of the shutter in real time. I hope that the shutter information provided by the small editor above will be helpful to you.
