I seem to be finding that even in fairly ok lighting my camera wants an extremely high ISO (6400) and if i manually lower it then the pictures are either really dark or the shutter speed gets lowered. Is this just because it is actually poor lighting and i shood wait untill the summer when there is lots of light. Bearing in mind i was in a large studio room in my school where the lighitng isnt the greatest.

Hi James, what settings are you using? ie, shooting in auto, shutter priority, aperture priority?
I use a k -X and rarely go above iso 800(unless I'm in dark interiors etc)
i use shutter priority, it with around 1/100 for portraits, and then the f/stop would be 5.6 and then the ISO kept going to ISO and me or my "teacher" couldnt figure out why.
I work inside doing pic,s of flowers or portraits. i use pg or av mode at 1250 or less , many times hand held. yes useing a kx camera.
sorry you didn"t say what lens you are useing. that could make a big change in out come your haveing in pic,s.
If you are shooting indoors and not using flash, then I think that 100th sec shutter speed is a little optomistic. If your subject is static then use lower shutter speeds with the image stabilisation on.
The Pentax KX is a great camera for low light situations.
okay, i was using the 50-200mm kit lens, and if 100th sec shutter speed is optomistic then thats all i need to know, i didnt know if there was a problem with my camera or there was infact too little light. It was hard to say because i dont have a device that measures the amount of light, i dont even know if there is one!! so thank you, i have just come back from walking my dog on a very sunny day and i was able to go up to around 2000th sec shutter speed with ISO around 200-800
I keep the camera on 100 iso as far as possible, occassionally go to 200, It sounds like you've got the auto iso feature selected which will keep increasing the iso until the camera likes the shutter speed, you can restrict the upper limit within the menu.
Personally I'd up the iso manually as required for each situation, keeping it at the lowest possible, prefer using a tripod / monopod for support rather than increasing iso.
okay, thanks for the tip but the lowest ISO on my camera is 200 and ive read that it can be extended to 100 but dont know how.
The iso is set to iso 200 for a reason. Base iso has a lower dynamic range than 200. ISO 200 hundred is the optimum minimum iso on your kx.
