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. Vignetting is a problem at 18mm f/3.5 and in critical situations you should generally stop down a bit. … 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 is quite slow on the D200 whereas the AF accuracy is generally fine here. All-in-all the Tamron is a decent all-round/travel zoom lens. Just make sure that you can live with its rather slow max. aperture at the long end which requires quite a bit of light or high ISO settings for stable hand-held photography. “¦ READ FULL REVIEW
