Simon, the DPReview photographer, made the following remarks about the Tamron 18-270 PZD:
In use this versatile lens is impressive: focus is snappy and is almost completely silent, you can get surprisingly close, and the image stabilization helps keep things sharp at the long end. Although at a pixel level the results betray the optical compromises involved, I see little to complain about at normal viewing magnifications (something you can hopefully judge for yourself using this gallery of raw converted images). More importantly, the value of a single, small and light lens covering such a huge range more than makes up for the slightly fussy bokeh, visible CA, and distortion at the wide end.
Accessories and add-ons
