Query: Disappointed

I recently purchased this lens after realizing I need an all in one for an event coming up. After hooking it up on a Sony Alpha 100 I was pretty disappointed, took about 20 test shots and everything seemed fine while viewing them on the computer until I looked at the actual size. Ghosting all over the images, blades of grass blurred and lost quite a bit of detail. Further tests all got the same result, slowing down and speeding up the shutter didn't help. Just to make sure my camera hadn't just broken I put on a 70-210mm Minolta lens and experienced none of that blurriness associated with the Tamron.
