problem with pentax optio s12
Welocme to the forum - please only post a message once in one section. I've deleted the other one. I would try cleaning the battery contacts and seeing if that solves the problem. If not, then it looks like a repair is needed. Is the camera still under guarantee?

Changing the battery creates uniform performance!
After the battery expired during serial shots at low light, I replaced it; then the camera produced the same result after every change I made in terms of both program and value. Has any one had a similar problem with his/her K20D? Could it be a result of sensor warming?

Exposure problems with new focusing screen
It's a known problem with split-screen focusing screens. Here this how every thing is placed inside of the camera. #1 is the exposure meter #4 is the focusing screen #7 is the AF sensor. I believe the rest is quite clear. As you can see the exposure meter must meter though the focusing ...

A setting not working
First you could try cleaning the contacts on the camera body and the lens with a soft dry cloth. That might be all it needs.

A setting not working
Hi Steve, I have experienced similar problems with older Pentax lenses (I have no Sigma lenses) As with your case they communicated with an older camera in my case a Z1, but not with an MZ6 or K10. In my case it was contacts inside the lenses that needed cleaning and adjusting. Regards - Stev...

K20D 'Chugging' - Help!!!!
The noise definately sounds like the sensor moving around, try doing a sensor clean and see what happens. But it does need to go back for repair or replacement, personally I would want the latter so I would insist on that from the supplier first.

K20D 'Chugging' - Help!!!!
It's not camera shake, the camera was resting on the table with a cable release. I do think it's the sensor moving around. But I've no idea why it should do that as no menu settings were touched. I did try a sensor clean, but the problem persists.

K20D 'Chugging' - Help!!!!
Actually I did a dust removal. I've now tried a sensor clean and that is exactly the same noise and feel. So I'm pretty sure the sensor clean is kicking in each time I take a photo.

K20D 'Chugging' - Help!!!!
The lens is fitted fine. Took hundreds of shots with it, no problem The firmware was updated at a previous repair. I did not really mean update but replace to make sure no faults are in the firmware. Like you said when you press the button it looks like the sensorshakes/cleaning goes on so does...

How do you keep your end clean
...of your lenses! I've just been looking at the pictures I took yesterday, had a wander along Brighton seafront (down for the day on work) with the 12-24 (Hood & Hoya Pro1 CPL) - and I'm very bored with seeing the same marks on every single shot. Argh! Obviously I had some dirt on the lens I ...

How do you keep your end clean
and I'm very bored with seeing the same marks on every single shot Its more likely the marks on your images are from dirt on the sensor, a lens would have to be really grubby or have a large spot of dirt before it affected image quality to that extent. Of course theres no harm in keeping lenses c...

I agree with Fatspider - a little dirt on the lens will not affect image quality. See: http://www.lensrentals.com/news/2008.10.30/front-element-scratches Much more likely to be dirt on the sensor that's causing marks on your images.

How do you keep your end clean
Thanks for your advice all - I will do some test shots tomorrow if the weather improves - have already had a good puff of the sensor, didn't see anything. The camera is set to auto-shake everytime I turn it on, so I'd expect dust to move about if it was on the sensor. The worst offender is in eve...

the photos show evidence of dust on the sensor. try a rocket blower and failing that the pentax sensor cleaning kit.

ok thanks. Had already used the rocket blower before posting, didn't see anything, but will do some test shots tomorrow to be sure. Finding those two adjacent shots at different appature made me think it was the sensor... although the CPL was filthy by the end of the Prom, so the Top Tips about spec...

This is the K-x? If so I think it has a dust alert system like the K-7. It should be in the setup menu, probably screen 4. Once selected point the camera at a blank white wall or a uniformly bright subject (I usually zoom in to a bit of bright sky) and press the shutter. The resulting display ...

Flossie, from http://www.bythom.com/cleaning.htm using a small aperture shows up the dust better than wide apertures. "The Test, Want to be appalled by how much dust is already on your sensor filter? Using a physically small aperture (e.g., a big number, such as f/16), take a picture of a pl...

The 'blobs' at top left of your photo's is sensor contamination. My recommendation is to get yourself an Arctic Butterfly from Visible Dust. IMHO it's the best sensor cleaner there is. It's all I ever use. I've never wet cleaned my sensors in 2 - 3 years. Using a blower to clean dust from a senso...
