I'd say they haven't succeeded yet - and the signs aren't great. They needed to produce a knockout offering with the EOS R and RP I think - they were so far behind that unless they did, they would struggle to build market share. I don't know how many more chances the market will give them to get it right, sadly.
I disagree. Given their history and given their capability, I give them an excellent chance to hang on to their current dominant position. They're still producing drool worthy glass.. the RF 28-70 F/2.. the RF 50mm 1.2 is the tits. The new 600 F/4 III is sublime.
