Gives you the option of both in body SR as well as in lens OS, plus it's HSM (e.g. SDM) which I am addicted to now.


Product Description

For the camera have anti-shake function in the camera body, this lens's Hybrid Optical Stabilizer provide not only anti-shake function for the camera body compensation, but also provide the function to compensate the image shaking in the view finder of the camera like anti-shake compensation built in the lens. Incorporating four Special Low Dispersion glass elements and three Aspherical lens elements provides excellent image quality throughout the entire zoom range. This lens has a minimum focusing distance of 45cm (17.7 inches) at all focal lengths and a maximum magnification of 1: 3.4 reproduction ratio, making it ideal for close-up photography. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarizing filters and the supplied petal-type hood. Incorporating super multi layer coating reduce the ghost in the backlight photography.

When the heck is it going to be available??? Amazon is selling it but the footnote says "Usually ships within 1 to 3 months."

1-3 months shipping. Sounds like the Pony Express is making a comeback.

You'll love Sigma's OS. I tried it out in a 150-500mm and I'm actually able to frame pictures at the long end rather than shooting and hoping to get something with good composition.
