Tamron announced a new lens— the 18-200mm f/3.5-6.3 Di II VC ( Model B018) for APS-C D-SLR cameras. This lens opens up varied photographic possibilities attributed to its optical and mechanical design in sync with modern times and technology. With a zoom range of 18-200mm, photographers need not go through the hassle of changing lenses while taking wideangle pictures or long distance telephoto pictures. From portraits to group photos and so on, this lens is an ideal choice. Keeping the aspects of portability and convenience in check, this lens weighs about 400 g. The lens also features Tamron’s Vibration Compensation technology. The lens offers quick and noiseless focusing in comparison to models with the usual DC motors. Constructed with 16 elements in 14 groups, the 18-200mm utilises an LD ( Low Dispersion) element to reduce chromatic aberrations. The lens’s circular seven-blade aperture diaphragm offers an appealing bokeh with point light sources blurring into naturally rounded shapes. The lens is also moisture-resistant. It further comes with a Zoom lock that helps in preventing unneeded barrel extension when the lens is pointed towards the ground.
