Never heard of anyone doing what I am looking at doing; I hope it works. I have a couple of camera stores in the my area that may let me test it our in store. Thanks for the idea.
I purchased a Z6ii and have using my older 70-200 2.8 VR II successfully. Later this year I am traveling to Antarctica and need a longer lens but I don't have the $ and want to travel light. I am contemplating using the 70-200 on the Z6ii with FTZ and a Telecoverter to yield 140-400 2.8.
How...
