Where do you get the information that the lens is a re-badged Tamron?
To my understanding only the Pentax FA 28-200mm f/3.5-5.6 superzoom was attributed to be a Tamron design, though this was never publicly acknowledged by Pentax.
lastdodobird, for this focal length, there were 2 different lenses from Pentax, the faster f3.2 version and the more common f/4 version. The former gets the better reviews while the f/4 version is an average performer. Please note that there were several iterations of the f/4 version.
