Verdict
Early user comments already suggested that new Tamron AF 18-250mm f/3.5-6.3 Di II LD Aspherical [IF] macro
does not only offer a longer range but also a higher quality over the old Tamron AF 18-200mm XR and the
lab results confirm these impressions. The results may not touch the sky but the new AF 18-250mm
delivers a very solid performance for most of the range. Unsurprisingly the weak spot is at 250mm @ f/6.3 -
stopping down to f/8 is a good idea here. Nonetheless the resolution characteristic is fairly amazing
regarding the extreme zoom range. Typical for such lenses the Tamron exhibits a quite extreme level of barrel
distortions at 18mm but at longer focal lengths to the problem isn't overly significant. In critical situations
you need to take care about vignetting at 18mm @ f/3.5 (~1.2EV) and less so at 250mm @ f/6.3 (~0.7EV).
Lateral CAs (color shadows at the image borders) are on a medium level except at 250mm where the problem can
get more disturbing. As to be expected for a zoom lens in this price league (<450€/US$)
the lens body is mostly made of plastic but the build quality is fairly decent. The AF speed and accuracy
are Ok. All-in-all the Tamron is a decent allround/travel zoom lens. Just be a bit careful regarding its
rather slow max. aperture at the long end. Unless you've a DSLR with built-in image stabilizer
(Sony, Pentax) you'll often find yourself choosing ISO 400 although this isn't really a problem with
the low-noise Canon DSLRs so far.
