Yes, except the best TC’s are made for mirrorless. Using a TC with the 180-600 lens on my Z9 is one thing. When I tried the 1.4 TC with the 200-500 on my D500 the results were disappointing. And what nobody has mentioned is that the Nikon TC won’t work with the Sigma lens. It would have to be a Sigma TC and it would bring the maximum aperture to f/9 which will cause focus problems with the D500.
I dont disagree. The better TCs are the optically newer ones made for the optically better mirrorless-designed lenses which have optical designs meant to work with these TCs. Combined with better-sensor mirrorless cameras, this combo results in professional quality TC images in my real-world experiences.
Cheers and best to you.
