Today I bought a Z TC 2x converter, to be used with the 100-400 that is arriving in the next days.
I was surprised a bit by hearing that there is something ticking/rattling inside if I shake it. I know that the old F-mount converters could rattle due to the aperture coupling lever when not mounted. But why does a Z converter have this rattling sound, if there is no coupling lever?
Could someone of you kindly try if your Z TC 2X rattles too?
