Minnolta Maxxum 5 w/ 16-80mm Sony Carl Zeiss

So, I dug out an old Minolta max 5 and started playing around with it. I got my hands on a Sony 16-80mm Zeiss and all the pictures taken looked like this - what looks like some sort of extreme vignetting/framing issue.

You're using an APS-C lens on a full frame camera, so that's the expected result.

I also have a Minolta 50mm prime and a sigma 28-300mm lens and they do not have this framing issue - they produce full unobstructive images.

Those are lenses designed for full frame cameras.

I was not using a hood. So, I am wondering is this a compatibility issue between camera and the Sony lens (camera too primitive for the lens) or is it a mechanical issue with lens?

The lens wasn't made to cover the full 35mm frame. It was made for digital cameras with APS-C sensors.
