E PZ 18?200 mm F3.5-6.3 OSS APS-C Telephoto Power Zoom Lens with Optical SteadyShot

Description:

This "Powered Zoom" lens produces smooth constant-speed zooms that can be difficult to achieve manually. Other features that make this lens an excellent choice for moviemaking as well as stills include a wide 11x zoom range and Optical SteadyShot image stabilization that can keep your subjects sharp at all focal lengths, even when shooting handheld.

Circular Aperture

When changing your aperture to defocus the background, the light sources appear blurred. This 'bokeh' effect of the blurred background can be enhanced with circular aperture blades used in this lens. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. ? lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result.

ED (Extra-low Dispersion) glass

As focal lengths get longer, lenses built with conventional optical glass have difficulties with chromatic aberration, and as a result images suffer from lower contrast, lower color quality, and lower resolution. ED glass dramatically reduces chromatic aberration at telephoto ranges, and provides superior contrast across the entire image, even at large aperture settings. Super ED glass provides enhanced compensation for chromatic aberration.

Features:

• Lens-based optical image stabilization
• Gyro sensors built into the lens detect even the slightest movement, and the stabilization lens is precisely shifted to counteract any image blur that might occur. The use of precision, quiet linear motors and technology inherited from high-end Sony professional camcorders results in exceptionally quiet, effective image stabilization that contributes to high-quality movies as well as stills.
