The 18-200mm f/3.5-6.3 DC Macro OS HSM Lens For Digital Cameras is an
all-in-one lens covering an 11x zoom from wide-angle to telephoto, with
a 35mm equivalent focal length of 27-300mm. An optical stabilizer (OS)
system is built into the lens, which reduces the appearance of camera
shake. This can be especially helpful when shooting at long focal
lengths or up-close macro shots. OS also allows you to use slightly
longer shutter speeds, making it possible to shoot hand-held in
low-light conditions. The built-in Hyper Sonic Motor delivers quick and
The 18-200mm's optical design incorporates double-sided aspherical
lenses which enable this extended super-zoom lens to be housed in a
compact and lightweight construction. Special Low Dispersion (SLD)
glass, correct chromatic aberrations, and Super Multi-Layer Coating
reduces flare and ghosting, to provide sharp, high contrast images even
in backlit conditions.
With a minimum focusing distance of 15.4" (39 cm) and a magnification
ratio of 1:3, the lens also acts as a macro lens. The maximum
magnification for each focal length is indicated on the lens barrel. The
product name on the front of the lens has been engraved, rather than
painted, so that when shooting reflective objects up close, the letters
will not show up in the image.
Thermally Stable Composite
TSC has the same level of thermal shrinkage as aluminum, with little
elasticity, especially in temperature changes. This gives the lens high
affinity to metal parts, and results in slimmer mechanical parts.
7 Blade-Rounded Diaphragm
The diaphragm creates aesthetically pleasing bokeh, or out of focus
areas in images.
Brass Bayonet Mount
The bayonet mount on this lens is made from brass, which is highly
accurate and durable, making this lens ideal for long-term use.
Compatible with the Sigma USB Dock, which can update the lens firmware
and adjust parameters such as focus.
