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. 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. 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?

Welcome to the forum .

The lens your using is designed for an APS-C digital camera , designated "DT" lenses .

The sensor is about half the size of a full frame camera , or in this case a film camera . The projected image circle isn't big enough to cover the film , as can be clearly seen .

You need a lens that is either for a film camera or full frame DSLR .

Sony A mount lenses work fine on a Maxxum 5 and later camera ( including the Maxxum 7 ) if they have a motor in the lens . Lenses that are focussed by the camera body will work on any Minolta A-mount  SLR , providing it's a full frame lens .

Something like a Minolta 28-105mm , Minolta 24-85mm or Sony/Minolta 24-105mm will work fine and give good results .

Most of the shots I've taken with my full frame Sony a900 and Minolta film SLR's are taken with one of these lenses .

Since buying a Sony a99ii I've also bought a Carl Zeiss 24-70mm f/2.8 , which is also compatible with your Maxxum 5 , but would likely be too big and bulky for comfortable use , even with the battery pack attached .

.

If you went for the 16-80mm as you wanted the wide end , you would need something like a Minolta 17-35mm to cater for that .
