When it comes to remotes, regardless of camera brand they all generally have proprietary remotes you can purchase fro your camera. If not there are always 3rd party ones you can pickup as well, the best part is you can get remotes for under $10. However with the advances in camera tech, most cameras these days come with Wifi included so they generally come with an app to control your camera from the comfort of your phone.
Now as far as setup goes, it’s super easy! frame your shot, test the lighting and make sure it’s exposed correctly. Then all you have to do is pose and shoot. If you are running the remote from your phone you’ll be able to see the frame on your phone screen and frame it as you shoot and you can get the exact shot you want. Alternatively you can also pickup an external monitor and have it face you if your camera doesn’t have a flip screen on the back. I recommend Neewers field monitor, I’ve been using it for a while and enjoy it quite a bit.
Give it a go and let me know what works for you guys!
