Can a 70d SLR set a square photo?

Yes, you can. A single-lens reflex camera can take square photos. There is a setting of 1: 1 in the menu of the single-lens reflex camera. Then, you can take a square photo by setting it to 1: 1, but it is usually more beautiful to take a photo at 3:2.

The SLR has only one lens, which is used for shooting and framing, and the parallax problem is basically solved. When taking a view, the light emitted by the object is focused by the lens, reflected by the oblique mirror and focused for imaging, and then reflected by the "roof prism" raised at the top.

Maintenance measures of 70d SLR camera;

The lens is the most critical and fragile part of the camera, so when using the camera at ordinary times, we should pay great attention to the protection of the camera lens, and don't get contaminated with dust easily, and don't let the lens be "dirty" by dirty hands. Only when it is absolutely necessary should we clean the lens.

When cleaning, it is best to blow off the dust with a balloon or gently brush it off with a soft brush. If you encounter stubborn dust, you must gently wipe it with special lens cloth or lens paper. Remember not to use soft-looking paper such as paper towels to clean the lens, because these papers contain wood pulp that is easy to scratch the coating, which will seriously damage the key coating on the camera lens.
