Alex,
The aperture makes a
huge difference in low light. When I went to Focus on Imaging a few years ago, and was doing some research on Sigma long lenses for Lello I had major problems with focus hunting on some of their long zooms. Test were in the exhibition hall lights. On the Nikon stand Foxy and I had a play with some Nikon excotica (fast lenses but same light) and the difference was incredible.
