Not an issue, just a review is now a little bit not complete or deceiving for a potential buyer. Yes, optics are most important, but in 2016 to have a lens with poor AF performance is a disaster, embarrassing, sad. People were returning this lens and I don't argue with that, it was sad little slow lens, not really usable in many conditions. I wouldn't want it without this firmware, at all.

 

Remark about existing firmware update which solves (serious) AF problem sounds like a reasonable idea, doesn't it?

 

Thanks.
