The latest design to emerge from the stable of superzoom experts Tamron, the AF 18-270mm f/3.5-6.3 Di II VC LD Aspherical (IF) MACRO was announced in July 2008. The length of the zoom range is almost as remarkable as that of the lens's name itself, with the 15x ratio covering everything from a 28mm...
Remarkable 15x focal length range; Impressive image quality in the normal to short telephoto range; Excellent resistance to flare; Effective vibration correction system; at least 3 stops benefit; Reasonably compact despite the long telephoto range
Slow and occasionally indecisive autofocus; Geometric distortion across much of the zoom range; Significant chromatic aberration at wideangle and telephoto (especially 270mm; Macro performance rather compromised (very soft at F6.3; focus shifts on stopping down; Uneven zoom action; zoom creep when
