At nearly 14x, Tamron’s lens is the world’s most powerful zoom and delivers all the photographic freedom of this enormous zoom range in a single, compact lens.

To prevent the lens from becoming bulky, the design concept of the AF18-200mm F/3.5-6.3 XI Di-II LD Aspherical (IF) Macro (Model A14), a popular lens among the world’s digital SLR users since it is the ideal high power zoom lens, was the basis for this new lens that features an expanded focal length to 250mm at its tele-end.
What are the downsides of a Tamron 250mm?
The only downside is the lack of IS, OS or VR (whatever Tamron wants to call it). At the wide end, with good sharpness at even f4, the lack of IS is no problem even in shady or heavily overcast areas. At 250mm, with a need to stop down to f8 or f9, means good natural light or a flash is needed for use without a tripod or other support.
