The Tamron's focus accuracy is fantastic ..... never any front or back focus
Actually I'm not sure if the the A9 stops down for autofocus ..... the size of the AF sensors will give the DSLR that edge in low light, for sports matches that's an issue ...... most birders don't wan't 25,600 ISO images anyway.
Does the Z7 Af at full aperture?
