Canon eos700d, when shooting with the display screen, the semi-secure shutter clicks.

There is still a big difference between viewfinder and monitor shooting. It's easy to understand if you know the following principle.

The most fundamental difference between the two is the difference in framing and focusing methods.

When using the optical viewfinder, the naked eye directly observes the picture produced by the light from the lens, and uses the phase difference focusing method to focus.

When the LCD screen is used for framing, the optical viewfinder is black, and the light enters from the lens and shines directly on the CMOS for imaging, and then the processor analyzes the contrast of the picture for contrast focusing.

Because the design purpose of SLR camera is mainly to find the field of view through the optical viewfinder, the contrast focusing performance of SLR camera is very general and the speed is slow, which is not conducive to snapshot. However, when focusing with a faster phase difference, an optical viewfinder must be used, so it is difficult to find a special angle of view such as a high position or a low position.

Sony's single battery is handled very well in this respect, and there is no such problem.

So if you shoot with a 700D-d monitor, the focus will be much slower and the reaction will be on the lens. This situation is more obvious when recording video, even in invincible rabbit. Or focus manually, this will not happen. I hope the answer will help you ~
