This is their chance I think to save people from going into the Sony a7r4. That camera is a beast. It's coming in September so I hope canon will announce something for their RF system, even if it means waiting past September for a better R model.
They better get to it. That new SONY a7m4 is THE camera that is going to push me to the dark side, especially after I have gotten a taste using the badass rx1rm2. (Sorry, Canon, you had nothing even comparable to that tiny badass that scores 97 on dxo, or I would have gladly given you that $4k that went to SONY and SONY periphs.) Ever since I started shooting SONY, I put my 5DSr away, except for commercial or forensics jobs or where I am doing 3D or auto-focus stacks. I even adapted all of my strobes for SONY, since even they sync better and more consistently, and hey- don't get me started on how STUPID the WIFi interfaces for Canon are. They have been stupid and unusable since the 6d or longer. Canon plus WiFi equals MIGRAINE, Sony plus WiFi works instantly every time.
As it stands, all of my L glass will work on Sony adapters just as well as a Canon adapter-to-RF, which was a pathetic solution, IMHO. An adapter was a real way to make my EF L glass collection feel obsolete. A native EF solution was the only way to go. RF completely negates the EF-M line. What, so will there be an adapter for that too? An adapter to make a RF lens fit a mirrorless APSC is the stupidest thing I can think of, but I bet Canon is working on one. Smart, guys.
Besides, go look at DxO scores, and see who scores the highest on lenses and sensors. I LOVE the colors my CANON produces, but those colors are looking less and less attractive with such great post options and getting to use GEAR THAT HAS NOT BEEN INEXPLICABLY CRIPPLED!!!!!!!!!!!!!!!!!!!!!
I would love to have a reason to stay with Canon after using them for the past 5 years and spending many thousands of dollars on only them, preferring even their peripherals, which are expensive but well-made. However, day by day I lose more and more interest with the direction they are going, with releases that come out 5 years behind SONY and others, with features I don't want or appreciate. I recognize the "RF Adaptergate" as my perfect jump-off point to leave Canon with minimal investment loss, and I CANNOT be the only serious, working, established professional considering this.
I am trying very hard not to be a troll with this one, guys, but I have definitely failed again. But when you pick up a APS-C g1m3, set it to RAW burst continuous, and it does one or 2 VERY SLOW shots before the buffer hangs, then you pick up a full frame SONY rx1rm2 no bigger than a cigarette pack, and the thing shoots 18 RAW faster than I need them, so fast that I want to slow it down, so fast that it outbursts a 1dx, it becomes a no-brainer: better colors mean nothing when all else is trumped; better colors are meaningless when you want decisive moments, sharpness, AF speed, RAW burst speed, processing and buffer speeds, insane plethora of options for buttons.......I could go on and on.
