Flickeroo tells truth about why that zoom isn't suitable for indoor available-light use.

There's good advise above about the A50/1.7 lens. It is a jewel and a joy.

Duz that just mean its made by another company for pentax?
It means that it was built by a third-party lensmaker for Pentax-mount cameras. Vivitar and other marketing firms (such as Sears, Porst, Soligor, et al) contracted with such lensmakers (including Tokina, Kino/Kiron, Tamron, Sigma, Tomioka, Chinon, Komine, Samyang, et al) to build lenses which could be fitted with bases to mount on many camera brands (such as Pentax, Canon, Nikon, Minolta, Olympus, Konica, et al). And lensmakers (such as those I mentioned, and Zeiss, KMZ [Russian], Hoya, et al) might produce Pentax-mount lenses as part of their regular production lines.

Such lenses, often (but not always) of good quality, might be made particularly for Pentax; or made so that they could be adjusted at the factory for any particular camera brand; or they might be fitted for use with adapters such as T-mount, T2, T4 or Adaptall. A photo shop would then only need to stock one set of lenses, but many adapters. If a Miranda user wanted the lens, the shop would fit a Miranda adapter to the lens, and everybody is happy.

These and other camera and lens forums are filled with discussions on the merits and qualities and lineage of third-party lenses. The 3rd-pary lens review database here has much information about many of these lenses. If you think of buying any particular lens, read the reviews, and don't be afraid to ask questions here.

I guess the first thing Ill be doing with It Is taking peoples photos, in mostly low light. thats why am really trying to figure out what lens would be inexpensive and right for that situation
Neither of the kit lenses are low light lenses (unless you use them with flash). For low light, you need f2.8 or faster. That's why some of us have recommended the old 50 f1.7, because that's the least expensive, high quality fast lens that you can use with the K-x. This is a lens capable of professional quality results (which, generally speaking, can't be said of the kit lenses). Pentax produced two manual focus versions of this lens: the A-series and the M-series versions. Optically, they are identical; the difference is that the A-series allows the camera's automatic exposure functions to work with the lens, whereas the M-series does not. This makes the A-series easier to use with K-x; but it also means you'll have to pay more for the A-series version.

Incidentally, having a fast lens isn't necessary merely for low light photography: it's also useful for achieving a narrow depth of field, so that only a very small portion of the photo (the face of the subject) is in focus. Professional portrait shooters generally shoot with fast lenses regardless of the light, because they want only the subject to be in focus, so that nothing else in the photo distracts from the subject. The more out-of-focus the background is, the more the subject of your portrait will stand out, producing a better portrait.

In terms of an inexpensive low-light lens which is good for taking pictures of people, a Pentax 50mm lens is hard to beat. The "M" 50 f/2 is just about the least expensive, and will still give you very nice results if used correctly. I suspect you can get one for about $20-30. The "faster" lenses (with a larger maximum aperture as described above, f/1.7 and f/1.4) are higher quality as well, but with more cost and thus diminishing returns. An "A" series lens will be easier to use, and again the "A" 50 f/2 is not very expensive, almost certainly can be found for under $40-50, and will also give nice results.

It would be a very reasonable approach to just get a camera body with an 18-55 zoom, and a book about photography, then see what else you might need later. This website has some handy tutorials, as does photo.net

A little more knowledge about how photography works, either practically acquired practicing with an inexpensive kit or via book-learning, will likely inform your next lens more than we all can. Good luck!

You can also go to keh.com. You'll pay slightly more than you would at ebay, but it's safer to buy from them.

If it's from a reputable buyer and you want it, go ahead and buy it. However, there's always an element of risk, regardless of how slight, when you buy something used sight unseen. New stuff has warranties and is easier to return.
