Tamron 70-300mm & LA-EA3

I'm looking to purchase the Tamron Di SP 70-300mm f/4-5.6 to use on a Sony a7 II with the LA-EA3 adapter.

Unsure about what the image quality and AF performance will be like. Any information is appreciated.

Also hypothetically if using this lens on an a7R IV and cropping to 520mm equivalent focal length, would the image quality be close to the Panasonic GX9 + 100-300mm?
