Welcome to PentaxForums! Let us know a little more so we can make a recommendation that works for you. What types of photography do you prefer doing? Do you have prior DSLR experience? What's your approximate budget? How important is weather resistance to you? I'm going to assume you want zooms for versatility.
Ultrawide: Tamron 10-24. I like mine. It's reasonably sharp (no ultrawide zoom will be tack-sharp) and, even though all ultrawides have distortion, the 10-24's distortion shows as stretching in the corners rather than a fisheye effect (it's a matter of personal opinion but fisheye looks unappealing to me). The Pentax 12-24 and Sigma 10-20 are also viable options. All 3 have reviews on the forum.
Normal: Pentax DA* 16-50. It's the "fastest" (wide aperture) zoom for low light and is weather resistant. Tamron and Sigma have similar zoom lenses but they are not weather sealed.
Telephoto: 2 ways to go here. The Pentax DA* 60-250 is the far superior lens, but it's a difficult decision because the Pentax 55-300 is so good for its price and very compact.
