Well, pentaxman, if the results come out as I've got them here, they seem unacceptable to me whether or not others have similar results at f/2.8 200mm, particularly as the corner sharpness does not improve impressively even at f/5.6.
What I was getting at was returning for exchange vs. refund. I would return it one way or another.
Since shipping is so expensive to Aus. I would seriously consider getting a refund instead of an exchange.
I bought 3 Tamron 70-200 F2.8s from B&H. The first one was decentered, the second one had a sticking aperture and the third one was decentered. I eventually gave up. The second lens (with the sticky aperture) was astoundingly good at all apertures and focal lengths - I wish I could have kept that one.
B&H was fabulous about exchanging lenses and eventually giving me a refund. I did not pay any shipping.
