Finally figured out the problem.

It is a diaphragm problem causing Err99.

If you are having this issue, this is the diagnostic:

At f/2.8 aperture is wide open, so no problems there, but stop it down to f/22 or smaller and press the DOF preview button and if your diaphragm is stuffed, then you will see the problem through the viewfinder - it won't open and close smoothly or properly.

Anyway, it's off to Tamron repair centre. I've been told it will likely be a AUD$150 or thereabouts repair...
