Conclusion: First things first; the AF 18-270mm f/3.5-6.3 Di II VC LD Aspherical (IF) MACRO undoubtedly represents an impressive feat of optical engineering, and Tamron has to be applauded for producing a superzoom that has significantly longer telephoto reach than its direct competitors without further compromising image quality. That's not to say the lens is in any way perfect, indeed it has much the same optical problems as the other superzooms we've tested.
Pros: 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
Cons: 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 not locked, Slightly sub-par build quality
Hands-on Review: Tamron AF 18-270mm f/3.5-6.3 Di II VC LD

Excerpt: Tamron is the master of extremely long, complex lens names and the Tamron AF 18-270mm Di II VC LD Aspherical (IF) MACRO is no exception. Be aware, however, that the last part of the lens's name ("MACRO") is a misnomer. Although this lens allows close focusing, it is not a true macro. Nonetheless, the 18-270mm has a remarkable 15x zoom range. It retails for $1,100, and is available in Canon and Nikon mounts.
Summary: A competitively-priced, general-purpose lens with the longest current zoom range and effective image stabilisation.Designed specifically for DSLR cameras with 'APS-C sized' imagers, Tamron's latest ultra-zoom lens, the AF18-270mm Di-II claims to offer the world's largest zoom ratio of any current lens. The 15x zoom covers angles of view that range from the equivalent to a 28mm wide angle to a 419mm ultra telephoto in 35mm format.
Pros: You don't like changing lenses, or have a camera body without built-in dust removal, and want a single, all-purpose lens that covers most shooting situations., You require an affordable 'walk around' lens for travelling or everyday photography., You want a long zoom lens with effective image stabilisation for both the viewfinder image and the capture system.
Cons: You have a camera with a 'full frame' (36 x 24mm) image sensor., You need a fast lens across the focal length range for shooting action in dim lighting., You plan to print your images to A3 size or larger., You need a distortion-free lens., You want macro versatility and performance.
