Hi just bought a used but 10/10 condition Laowa 100mm f2.8 Macro. This is my first macro, manual lens and that too from a third party. Unless I missed something I am unable to take a shot when I press down on the shutter button. I have it set to manual operation mode, and using focus peaking to focus, the aperture is set to 2.8 but the R6 is reading it as F00. Do you think I need to update the firmware on my R6, or the lens or both?
