Tamron 28-75 f2.8 or Sigma 17-70mm f2.8-4?

I want a decent lens for everyday, but firstly for a wedding. I enjoy taking candid portraits but also like getting decent bokeh and nice sharp images.

I've found my K5 picky in low light, and I'm drawn to the Sigma's fast and quiet AF, but the Tamron's quicker speed even at a slightly longer reach means it has an appeal.

Do you have either? - What do you think?

Which would you go for?

The tamron is not fast to focus in low light, the sigma probably focuses faster but you lose the wider aperture at the long end....

I have the older version of the Sigma 17-70 f2.8~f4.5 and it focuses quick enough for me, plus, I think it offers more flexibility for a wedding photographer at the wide end when in a tight space such as a chapel or register office. I love mine and prefer it even to my Pentax 18-135, though some might think me a Philistine for saying that....

What you need are lenses, more lenses, bigger lenses, better lenses, faster lenses, and when you have these, your pictures will be perfect!
