Re: questions about sigma lenses

1) autofocus performance in night depends mainly on your camera, but the f2.8 will focus better than an f4 or f5.6 lens

2) if you are shooting at true life-size macro for static objects you would normally need a tripod and patience to compose the shot so the OS does not seem a key feature. If you can manage to get close to live bugs at near life magnification you might want OS.
