New 18-200mm F3.5-6.3 DC OS

Equipped with Sigma’s own unique technology OS (Optical Stabilizer) function.
Two SLD (Special Low Dispersion) glass elements and two aspherical lenses provide excellent correction for all types of optical aberrations.



The Sigma Corporation is please to announce the new 18-200mm F3.5-6.3 DC OS lens. This high zoom ratio lens is exclusively designed for digital SLR cameras and is capable of covering a wide range of focal lengths from wide angle to telephoto. It is equipped with Sigma’s own unique technology OS (Optical Stabilizer) function. This function uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilizing lens group, to effectively compensate for camera shake. It automatically detects movement of the camera and compensates for camera shake when shooting moving subject such as motor sports. Two SLD(Special Low Dispersion)glass elements and two aspherical lenses provide excellent correction for all types of aberrations. The super multi-layer lens coating reduces flare and ghosting. This lens provides superior image quality throughout the entire zoom range. An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using circular polarizing filters and the petal-type lens hood supplied.

Did TCW mention about the price?

[maxheadroom]

do let me know the price....

i have a few sigma lenses, and this one, for some reason, still have its focusing ring turning when it's focusing. dun why sigma still dun want to make those dual focus or DMF mechanisms.

[ortega]

satay16 i don't think you have the OS version right?
it might be different from yours

must wait and see

100% sure this lens's focusing ring rotates. you look at the focusing ring, can see the distance markings on it.

[ortega]

are there lenses where the focusing ring does not rotate?

for sigma, they sometimes use this dual focusing mechanism that slides in and out when you want to disengage focusing. for most of their HSM lenses, theirs is the same as canon's DMF, it doesn't rotate unless you turn it.

[ortega]

ah i learn something new

but i do not own a sigma yet

[maxheadroom]

Anyone getting it..??? Can confirm the price?

[maxheadroom]

Call the Camera workshop and CP, they said not arrive in Sore yet....
Got me excited awhile. Thinking buying it after work.

[satay16]

my guess for this lens is that it will be pretty noisy, but dun buy this lens too quickly. so far, the other lens(and only too) with OS has suffered pretty bad reviews about its OS causing a significant shutter lag.

[ortega]

i have tried the other one
and i only turn on the VR when I need to use a slow shutter speed
so i can live with the slight delay for the VR to kick in.

meaning... still best to stick with the VR of nikon... or the IS of canon...
