Question about Tamron AF 150-500mm F/5.6-7 Di III VC VXD Fuji X

Did I get a bad version of the Tamron 150-500 XMount because it focuses back and forth in low light conditions. Or is the Tamron designed to focus correctly and quickly only in bright conditions?

The Tamron doesn't have a firmware update yet, the one for the Fuji came out recently. In that case it has to do with the camera, I just don't understand why my other lenses: 56/1.2, 33/2.8 and the 8-16 focus quickly. Would love to see a comparison between the 100-400, 150-500 and the 150-600. My a7iv with the 200-600 is just faster, no matter what the lighting conditions.

A low-light zoom will no longer function optimally in poor lighting conditions. And the AF comes from the camera. The problem is more likely to be found there. Not all Fuijis are known for fast AF. Is there a firmware update for the Tamron?
