Problem with sigma lens and k-70

Hello, I'm currently in possession of both a k-50 and a k-70. I recently bought a second hand lens from eBay which is a Sigma DG150-500mm (APO HSM). The lens works perfectly on the k-50 but for some reason, it doesn't work on the k-70. Whenever I attach it to the k-70, the camera completely freezes up and you have to remove the battery for it to turn off. I don't believe the issue is with the k-70 as all the other lens still work perfectly when attached to the camera.

Any idea why this problem is occurring and what's the best way to solve it?

Kind regards,
