Using Canon 5d Mark 4, 70 to 200 zoom - 2.8 with Teleconverter 2x Mark 3.
Question: is it possible to add (stack) additionally a 1.4 Mark 3 Teleconverter to the above set up?
Understand this will narrow aperture, but this will be day light shot. Due to very infrequent use, I do not want to buy another telephoto.
Will appreciate advice. Thanks
Definitely possible, with primary caveats being loss of autofocus and requirement of absolutely impeccable photographic technique.
Check an October 2018 article by George Lepp in Outdoor Photographer titled "Keeping Your Distance and Claiming Your Space." Sorry I can't provide a link, but a search of Lepp and the article title quickly brings it up.
