Can SLR cameras be controlled by Bluetooth?

At present, all SLR cameras on the market do not support Bluetooth, but many of them support wifi to connect to the local area network, and then control it through the mobile APP. For example, Canon's 70D/7D/6D, after opening the corresponding settings in the camera, download the corresponding mobile APP and you can connect. Oh, it is easy to use.

I hope I can help you, wish you a happy life, and remember to adopt when you are satisfied!
