Objavljeno 8 okt, 2007

Podjetje Sigma, ki se ukvarja z izdelovanjem foto opreme, je predstavilo nov objektiv Sigma 18-200mm f3.5-6.2 DC OS HSM. Nov objektiv je namenjen vsem, ki želijo veliko fleksibilnost, hitrost in majhnost v enem. Objektiv se ponaša z več kot 11-kratno optično povečavo, hitrim in neslišnim ostrenjem tipa "HSM", popolnoma notranjim ostrenjem "IF" in sistem premikanja leč "Optical Stabilization", ki poskrbi za kristalno čiste posnetke tudi v slabši svetlobi. Objektiv nosi oznako "DC", kar pomeni, da je prirejen za digitalne SLR kamere z manjšimi tipali.
Objektiv je kot nalašč za vse popotnike, ki potrebujejo majhne dimenzije in veliko uporabnost, hkrati pa želijo dobro kvaliteto slike, ki jo nov Sigmin objektiv premore.

Compact, Lightweight Superzoom lens, with high zoom ratio 11:1

Sigma Corporation is pleased to announce the launch of the new 18-200 F3.5-6.3 DC OS lens.

11.1 high zoom ratio lens is designed exclusively for digital SLR cameras and incorporates Sigma’s original OS (Optical Stabilizer) technology.

This high ratio zoom lens incorporates Sigma’s original OS (Optical Stabilizer) function and exclusively designed for digital SLR cameras. It is perfectly suitable for low light conditions, indoors, at dusk and telephoto range. SLD (Special Low Dispersion) glass and aspherical glass provide excellent correction for all types of aberrations. This lens has a minimum focusing distance of 45cm (17.7”) throughout the entire zoom range and has a maximum magnification of 1:3.9. The inner focusing system is suitable for using a petal-type lens hood supplied and also circular polarizing filters.

Sigma’s own unique technology OS (Optical Stabilizer) function
The 18-200mm f3.5-5.6 OS is equipped with Sigma’s own unique OS (Optical Stabilizer) technology. This system uses two sensors inside the lens to detect vertical and horizontal movement of the camera by moving an optical image stabilizing lens group, to effectively compensate for camera shake. It also automatically detects panning movement of the camera and compensate for camera shake when shooting moving subjects such as motor sports.

Excellent Optical Performance
A Special Low Dispersion (SLD) lens and three aspherical glass elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range. The super multi-layer lens coating reduces flare and ghosting while producing the best color balance.

Enables close-up photography
This lens has a minimum focusing distance of 45cm through entire zoom range with a maximum magnification of 1:3.9 making it very convenient for taking close-up pictures.

Inner focusing system
Because the front of the lens does not rotate, circular polarizing filters and a petal-type hood can easily be used.

Magnification scale
A magnification scale is displayed on the lens barrel, ensuring ease of use.

Zoom lock switch mechanism
A zoom lock switch mechanism is provided to prevent the lens from creeping due to its own weight.

*Vignetting will occur if the lens is used on digital cameras with image sensors larger than APS-C size or with 35mm SLR cameras.
