I'd love to hear from anyone who has these lenses, good or bad.
My two cents - 28mm indoors, RESONABLE low light with enough room is wide enough. Where I got into trouble with that range was in a room full of people and not much wiggle room. The lens IMHO is exceptional quality
Because of this and other interests I went for the Pentax 12-24 as well. Lots of snaps with the 12-24 , not so many people / portrait shots, however Xmas is coming with the traditional family get together so I will have an opportunity there. The 12-24 is f4 so conisder that as well.
Not sure on the Sigma 17-70 but others seems to be very happy with it. I alos ues a 50 f1.7 a fanstatic portraint lens in low light - again given enough wiggle room.
