3.3ft Shutter Release Remote Control with 11.4ft Extension Cable 2.5mm, AFUNTA RS-60E3 Wired Remote Control Switch Cord Replacement Compatible 70D 100D 1200D Digital Camera DSLR

Yes! My Canon EOS Rebel T6/1300D camera is in excellent working order. It also has a 1/2 shutter release feature, which allows you to set the focus by partially depressing the shutter release. This is one of my favorites and I use it all the time. I hope this has been of assistance.

I don't think there's any reason why it shouldn't be done.

It will begin and end the video as if you were taking a picture with the shutter button. At least on my Canon camera, you only need to press one button to start and stop recording.

Is it a Canon camera that you're using? If your Canon has an E3 socket (read your instruction book to find out), does it have "The shutter release remote control is compatible with Canon E3 socket cameras"br> This accessory is compatible with my Pentax K-SLR camera. 50, which has a socket that is similar. A Canon model T7 is something I've never heard of before. "Extension System Terminal: T7" is a specification from T7. RS-232C Remote Switch 60E3 is a type of terminal. According to my Google search, it appears to be compatible with a Canon T7.
