Can I take a DSLR on a plane?

SLRs can be brought on board the plane. It should be noted that if it is a camera with a camera, it is not allowed to be turned on midway on domestic airline flights.

Single Lens Reflex Camera, also known as SLR camera, refers to a camera that uses a single lens, and the light shines on the reflector through this lens, and the view is taken through the reflection. The so-called "single lens" means that the photographic exposure light path and the viewing light path use one lens. It is not like a rangefinder camera or a twin-lens reflex camera that has an independent lens for the viewing light path. "Reflective" refers to a flat mirror inside the camera that separates the two light paths. The first SLR camera was developed in 1909. Since the 1970s, this technology has been widely used, and SLR cameras have become the new favorite of advanced photography enthusiasts and professional photographers.
