A bit skeptical. The biggest advantage for me is the burst rate and live histogram, but the newest Canon 90D, released last year, matches mirrorless FPS and also has a live histogram. The weight's advantage isn't as big of a deal as a lot of people have claimed because many of us have to deal with big lenses anyway.

The low/night light features are cool, I think, but my "mentor" who's a professional night photographer, thinks it's all a gimmick. It definitely lowers the bar for entry in this field for people who don't do a lot of night photography. The vast majority of my shots are under full sunlight or heavy stadium lights, so it's not that big of an advantage for me.

There's going to come a time where mirrorless will reach beyond what mirrors can do, but I don't think we're there yet.
