My Sigma 150-500 arrived today,

as soon as you crop it, things start looking pretty dire.

The lens looks faulty but there is a a chance that 1 of two issue could be the cause

First is the lens is unfocussed, Look at this from the bigma pretty sharp ? but look again at 1:1 at the beak which is outside the field of focus and you see similar haloing

The other possibility is vapour left coating the lens elements after manufacture , I had an 18-50 DC that had the same was pretty poor out of the box but a quick wipe on both front and rear elements with a decent cleaner like 'Eclipse' and it was like a new lens sharp and contrasty with no hint of haloing
