How do you use Sigma OS?
I have the same lens and have shot BIF using OS mode 1. Position 1 compensates for movement along both the horizontal and vertical axes, and position 2 along the vertical axis only which allows for panning the camera.
On your Sigma lens are using OS 1 or OS 2?

What are contemporary lenses?

Are Sigma lenses stabilized?
It includes a petal-shaped lens hood and has a close-focus distance of 9.5 inches. The 18-50mm F2. 8-4.5 DC OS HSM lens is one of just a few from Sigma to include image stabilization (which Sigma brands as OS for optical stabilization), a technology that counteracts camera shake to cut down on blur.
Is image stabilization necessary for video?
Having a stable image is even more important in video because people can see any shakiness. With a still photo, stabilization is only needed for the fraction of a second that image is exposed, but with video it needs to stay stable for the entire length of the clip.
