Which Focus Motor??

[Gazbag]

This may seem a silly question to some, but it is one I need to know before I look at replacing a lens

My sony has an inbuilt focus motor, and the lens I want also has it own focus motor (HSM), which focus motor will drive the lens when on the camera

Thank you.

the in-lens (HSM if it's a Sigma)
