-Great focal range

-Screw-driven AF (as opposed to SSM)
-Hood could be sturdier
-Full frame construction takes out wide end on APS-C
photos are a little soft wide open, stopped down to f/6.3-10, they become almost 3 dimensional. Detail resolved is excellent, IQ is well above regular consumer lenses, definitely worth of Tamron's SP designation. Sure, it's not the same quality as the most expensive G or CZ lenses, but it's also a fraction of the cost.
the color coming from this lens is very nice. Contrast benefits from a slight boost in PP, color from a very slight vibrancy increase in Aperture 3, though this will be more to individual photographer's tastes, IMO. Either way, colors are accurate and well saturated.
Build is very good. Plenty of metal, nice weight and heavily damped zoom and focus rings. Zoom creep is non-existent. The only thing that irks me about the build is that the second zoom extension is plastic, while the first is metal. Still, it's better built than cheaper lenses. Front and rear elements are very obviously coated, as shown by the conspicuous bright green tint.
Distortion & Flare:
Distortion is well controlled. Flare appeared when pointing directly into the sun with the sun near the edge of the frame. Also, i had no issues with vignetting on my A200 at any focal length/aperture
a great lens, worth of being called professional grade. I would've paid the current new asking price of 399.99, but getting it for only 220 makes the whole deal even sweeter. A great walk around lens for FF and APS-C alike, though APS users will need something wider, as 24 becomes an equivalent 36mm.
With my own review system, it scored a 97/120, while the Sigma 18-125 scored 65/120 and the Tamron 28-105 scored 56/120. For comparison, the Sony 18-70 scored a 37/120.
