I would like to see a review between the ef 100-400 and the rf 100-500. I have a bad case of GAS; however i don't have a bad case of CASH. Camera body is the R6
I would keep the EF 100-400mm.
Unless you have a lot of cash or credit.
I have debated this for when I get a RF camera and have come to the conclusion that the EF lens and my 2X TC will do just fine as that combo is so sharp and will supposedly be better on the RF camera.
