Tamron's new 18-270mm...  ...and the previous version.

Tamron has introduced an updated version of its 18-270mm travel zoom lens, the Tamron 18-270mm F3.5-6.3 Di II VC PZD model B008TS. Unlike the previous version (model B008), the B008TS features a fluorine coating on the front lens element, in addition to the existing Broad-Band Anti Reflection coating. With the fluorine coating, Tamron says the lens element is water and oil-repellant and less likely to be harmed by dirt, fingerprints, moisture, and dust.

While the fluorine coating is the new model's biggest change, the folks at Imaging Resource have pointed out some minor cosmetic changes, as well. The gold trim ring found on the previous lens model has been replaced with a silver ring; as well, the overall lens design has been simplified, with both the zoom ring’s and focus ring’s styles being altered. According to Tamron, these changes ‘create an external design with a high-grade feel.'

According to Tamron’s website, the new lens will launch tomorrow in Japan with Canon and Nikon mounts for ¥83,000 before tax.
