True, Olympus had backlit buttons on their entry level DSLR E-620 nearly a decade back. Even I end up using a headlamp(since I dont shoot landscapes/Astro I can get away with normal white led to setup camera for camera trap) while working in dark.Nice feature but slow to arrive. I have been using a small red beam flashlight for night photography when looking at buttons. This would be useful for me.
Really? I switched this summer from Canon 5D4 to Nikon D850 and I find the backlit buttons indispensable. This is assuming the user does lots of night photography, which I do. it's one of those things like (for us older folks) a microwave oven. I grew up without it but once I got one I don't know how I lived without it. Canon should have put it in the 5D4 because this is one of several features that makes the Nikon D850 superior to the Canon 5D4 in my opinion. (Yes it's an opinion, but having used both extensively I feel it's an informed opinion).The illuminated buttons on my Nikon weren't much of a help for me. They were ok, but mostly to advertise as a feature. Maybe Canon's will be better??
Nuh, the rest of the buttons illumination will be available via a service centre upgrade at charge.Gotta save something for the EOS-1D X Mark IV
It's really helpful for night photography when it's cold. If you can't feel the button through your gloves and can't see it either, it's really easy to hit the wrong one regardless of how well you know your camera.Backlit buttons is for noobs. A good photographer knows where the buttons are in pitch dark.
