Making a lens with such an extraordinary range is always gong to require some pretty clever engineering, and Tamron's design team have clearly been burning the midnight oil on this one. The optical formula features no fewer than 18 elements in 13 groups, including three aspherical elements and two Low Dispersion (LD) glass elements for the control of aberrations. A 'double-trombone' mechanical design allows the lens almost to double in length between 18mm and 270mm, whilst keeping the overall size and weight very similar to competing 18-200mm lenses. The 18-270mm F3.5-6.3 VC will compete head-to-head in the 'stabilized superzoom' market with the Canon EF-S 18-200mm F3.5-5.6 IS, Nikon 18-200mm f/3.5-5.6G IF-ED AF-S VR DX, and Sigma 18-200mm F3.5-6.3 DC OS, but offering the benefit of substantially extended telephoto range. Tamron hails it as 'The Ultimate All-In-One Zoom: Longest, Steadiest Lens On Earth', and while it seems likely that this phrase may have lost something in translation, it does give a good impression the lens's appeal. But can such a general-purpose optic actually be any good?
