I'm not one of the bemoaners.Just a fun poll if you've read this far: what is the most recent purchase you've done of EF glass? Personally, it was getting the 50/1.2 and 8-15 fish in 2011. Anyone buy new EF glass more recently than that? Anyone buy new EF glass since RF came out?
But I did buy a 100-400 II L either in late 2019 or early 2020 (but it was before the RF 100-500 came out). Not all that long before that I bought some of the low-rent primes. I'm new enough to this that every single lens I own (other than maybe a rebel kit lens) is after your cutoff date.
No I did NOT throw a fit when an RF replacement came out shortly afterwards, because I have, and will again in the future, use the lens on my M series cameras, and I can't do that with the RF model. I would probably buy the EF today, in fact, had I not done so in the past. (And as far as I know this one hasn't been discontinued, yet.)
