Let's say that's not the most explicit and clear response.
To be honest I think I don't care it isn't like my K3 can't do thing it was able to do before or even I could not put the best Pentax lenses on it. There a single consumer grade lens involved with a KAF2 variant still sold and another variant that can be got used for 1/3 of the price.
In a sense, it is more annoying to get many lenses that focus on FF pro market that I don't care of at all because I target more sub $1000 lenses that are also reasonably small/light.
But even, that, I can't really complain and that not really reasonable to complain about that. I have quite decent body that has access to decent lenses. That's all I need.
Sure... it could be better, but what could not ? And it could be much worse too... Like all the recent DFA lenses and the 16-85 being KAF4 and incompatible or the KAF4 mount bodies not accepting KAF2/3 lenses. This isn't the case. There no weird path that would end up with un-happy crewed customers except insisting on getting the 55-300 RE instead of DA/DAL/HD DA 55-300 on K3 or older hardware. But doing that you have either to be sloppy or stubborn.
