Sigma 17-70 apperture

Good day from down under,

I'm looking for a faster mid-range zoom to supplement my Sigma 18-200 . This will mainly for in door photography, family gatherings and the like.

While I've enjoyed the 18-200 it's quite slow. ie: it's about f4 at 20mm and is already f5.6 at approx 60mm. And my Kx sometimes struggles with the autofocus.

The new sigma 17-70/2.8-4 seems quite interesting and may fit the bill for what I am looking for. The reviews that I have seen are universally positive, got a wide zoom range and is not too expensive.

However, does anyone know what are the maximum apertures at various points in it's zoom range?

Are there other affordable (< $600) zoom lenses that could be recommended for indoor shooting?

Cheers
