Thank you all for your feedback.

I'm going to try it!!

I haven't had any issues since I upgraded the firmware. I have used the 200-400 several times after the upgrade with M50, 7D mk ii and 1DX mk ii bodies without problems. I have probably not seen any improvements though I think the 7D mk ii behaved slightly better than I remember. However, that is probably just imagination. Note: All usages were normal usages and not test of the firmware upgrade. In fact, I didn't think about the firmware upgrade until I saw your last post.

Oh no! He should know by now that "equivalence" is a forbidden word for APS-C but perfectly allowed for 1” Sonys, compact cameras, smartphones and maybe even for M43s.
