I know nothing about the Tamron 200-500, so can’t help you there. And I agree that the Pentax 150-450 is outrageously expensive (for a 3x zoom).

But which version of the Sigma 50-500 did you have? I am very happy with my  50-500mm DG OS HSM version. It is my go to lens for wildlife ‘Big’ and ‘Small’.
