Just been to the Photography Show 2018 at the NEC, Birmingham, UK. Nice to get the chance to handle the K1ii and DFA* 50. The Pentax/Ricoh guy was saying they had been briefed about 1.4x and 2.0x TCs on the road map... ...and probably before any new limiteds. Shame that road-map was not on display!!! ;-)

I was sort of tauht in the old school---to keep your TC's away from zooms on the theory that the zooming had already pushed the optics to the limits
Generally true but I have found the HD 1.4x RC works fine with the DA*60-250 and the DFA 150-450.

appreciate the FA feature added I have the older manual ones.
That was probably true until at least the 80's. Any star quality tele zoom will do fine with a TC. I remember seeing a pop photo article mid 8s and 3 of the top 10 rated lenses at that time were zooms.

I've had as many issues with older primes as with older zooms. The CA and purple fringing of those older lenses can be magnified to un-acceptable standards, but manu on consumer glass. The F -70-210, A-400, come to mind.
