Question about Tamron AF 18-400mm f / 3.5-6.3 Di II VC HLD, Canon EF-S

Good day
The Tamron AF 18-400mm with the Canon EF mount can be used on a Sony, you just need a mount converter. I have the Sigma MC11 converter which works very well on the Sony. The autofocus works very badly or not at all. It always depends on what focal length you use, with tele it works very badly. But all the Exif data is transferred, which is very good. With this lens on the Sony I only shoot with FOCUS PEAKING then the pictures are just great. But if you want to work with autofocus and that's all you want to use, then it's not a good choice.
