What compels me to stand up on the Mount and shout this for all to hear?
It's because I've shot with a Dual Pixel sensor for more than three years now. :-D
Granted, I was more than a bit skeptical with the idea of the dual pixel sensor before I took the leap and purchased the 70D back in 2013. Not just a new sensor, but an entirely new technology in that sensor. Well to say that I was pleasantly surprised would be a vast understatement. It performed beyond all of my wildest expectations.
I immediately realized that Canon held in its hands a technology that could shift the entire Paradigm,
across the complete scope of Digital Photography. I vowed then and there to never buy another camera without a dual pixel sensor. OK, I did sneak in a couple of 1" sensor cameras in the meantime, he he

. But I fervently wished that Canon would incorporate this technology in All of their new releases.
So yes, admittedly it's been a long wait to see DPAF finally reach the M-series (I give a nod to Sony and Fuji with their AF advances in the interim). But for those of you who haven't had the experience of using DPAF coupled with that excellent and intuitive touchscreen interface, you are in for a real treat. Be it Stills or Video. Just ask any of the 70D/80D folks out there about it. It really works.
Sure, I know the M5 doesn't tick all of the boxes on everyone's wish lists (no camera can of course), but I truly believe this camera is going to make a lot of people very happy, by way of that wonderful dual pixel sensor.
Put me on that short list. Happy shopping all!

ps. For those curious, here's a (full size) sample from the 70D's older lower-resolution 20 MP dual-pixel sensor. Shot at ISO 800 with zero sharpening or noise reduction...
