I’d think most people were pleasantly surprised with the release of the EOS RP. Full-frame mirrorless cameras were getting increasingly sophisticated, which is a good thing, but they were getting increasingly expensive along the way. After all, it’s the enthusiast and prosumer crowd that wants mirrorless cameras more than anyone else.
Top tier professional photographers are still largely sticking with traditional DSLRs, for now. The only full-frame mirrorless options for that growing crowd of serious but not seriously paid photographers were the now-5-year-old (time is really flying) Sony A7 II or the even older and clunkier A7. Anything with current tech would run you $2,000 minimum, namely the A7 III. I’m not saying this camera wasn’t an absolute steal considering what it can do, but $2,000 is still a lot of money for most people who do not shoot full-time for a living and leaves little room for modern, mount-native glass. If only there was something to fill that gap.
