Originally posted by ekim12987 I'm new to dslr's, but have a *ist DS and was interested in getting a better lens for it. I don't know a whole lot about whats good and what isn't. I found a few lenses that fit my budget, but I wanted to get others opinions on. I'm looking for a lens with decent zoom, I plan on shooting indoors where lighting may not be very good. I understand that my budget is limiting my decision. If there are other lenses that are recommended, please let me know. The lenses that caught my eye are:
Pentax SMCP-DA 50-200mm F4-5.6 ED Auto Focus (I found that for $199) and the
Sigma 28-200mm f/3.5-5.6 DG (I found that for $289). $289 would be the most I would be able to spend. Does the $100 difference between the 2 lenses justify itself? Any thoughts or comments are appreciated.

Do you need the full 200mm for your indoor shots? If not, for your budget I'd consider:
SMCP-FA 50mm f/1.4 ($180 - $220) Simply the best bang for the buck low light lens available
SMC-M 135mm f/3.5 ($30 - $120, generally $60-70) Having f/3.5 at 135 mm is very useful, I've found. And this lens is sharp as a tack.
If you feel that you would occasionally like more reach than 135mm, you could get a used Tamron, Kenko or sigma TC (Teleconverter) that extends your focal range by 1.4, 1.7 or 2.0. You would lose speed when extended, but it would give you a good useful 200-270mm for outdoors or well lit indoors. they'll run you between $40 and $120 used.
You could also find a pretty good off-brand 135mm fast prime f/2.5 or f/2.8, something like a Sears or Tokina for $30-$40. That extra stop gets you a surprising number of 'keepers' in low light situations.
(and don't be put off by 'off-brand' - these lenses are often made by reputable manufacturers . For example, I just bought a nice Sears 135mm f/2.8 in the marketplace forum that's very sharp, close focus, etc, for $40.)
