Can you share some of you techniques?
I know, it must sound strange, but this is the way I shoot. I do not have any secrets to share.
If I'm not shooting people or moving objects, there is no problem since I can simply do longer exposures. If I am shooting people, then, to the extent it is possible, I maximize available light, bumping ISO as high as needed to get the shot. I do not think everyone uses ISO 3200 on the K20, but they should. No, you can't make 30 x 40, award winning posters at ISO 3200, but you surely can get printable shots which preserve the memory, sometimes with very surprising quality--it does take practice and exposing as far to the right as possible is essential. I have to believe %95 of prints are smaller than 8 X 10.
Sometimes I will manually focus in low light, but often the K20 AF more than does the job for me with my Tammy 17-50mm. I have faster primes too, like the Pentax Auto tak 85mm f 1.8 which can help too. But I guess I just go to the shot with the mindset that I am not using flash and will do all I can to get the best shot I can. Here is AF in low-light, in the dark of the woods, with only a lantern which was, BTW, low on oxygen and dimming down a lot. From the deep & dark back woods of New Hampshire, with no PPing at all, just raw to jpg and resampling. Wide open, ISO 100 and hand held:
