Please note: the original post mentioned the EOS R6 Mark II, that was obviously nonsense…
Canon appears to be rather active in discontinuing their EF and EF-S lenses at fast speed. Latest reports state that more lenses have been retired.
asobinet.com reports a tweet by photographer Kimio Tanaka, stating that Canon is discontinuing EF and EF-S lenses (machine translated):
CANON’s EF / EF-S lenses for SLR cameras are “low in stock” and “discontinued” at a tremendous speed (that is, production has been discontinued, and the rest is only in market stock).Nozomi Tanaka (@thisistanaka) October 12, 2021
Currently, about 70 are “on sale”, but about 25 of them are treated as discons. I don’t want to think of a single-lens reflex camera as a light in front of the wind, but the remaining expectation is PENTAX. I want you to do your best.
The EF 40mm F2.8 and EF 85mm F1.2L II show up as discontinued, according to asobinet.com (the latter is not in stock at B&H). it seems Canon’s stock of EF and EF-S lenses is shrinking pretty quickly. The future is the RF mount, that seems ascertained.
