K-x SR in Cold Weather

I recent used the k-x in the outdoor cold weather(-25C or -13F), alot of the pictures came out blurry, even at 1/125s, Does this have to do with the SR system? I didn't try to disable the SR. But I never experience this issue at warmer weather, and the shutter speed is much slower. Does the cold weather affect the SR system?

Weather that cold can definitely affect the inner workings of a K-x. I've used my K2000 (K-m) in -20F weather, but only for a few minutes to make a critical shot. The picture came out decent/repairable, although there was a large amount of noise even though I only used ISO 400.

Unless you're using the K-7 (cold resistant) I wouldn't suggest using a Pentax DSLR in that kind of weather. For all we know, your SR system might have even frosted over (if that's possible).

Happy shooting

Some users have reported shake problems at around 1/125 second with the K-x.

Is it possible that you were going repeatedly inside and outside while shooting? Sounds like you might have gotten some condensation either in the lens or on the sensor...

There is also a possibility that the photographer himself is affected by the low temperature and shakes more than usual.

I guess it is the cold weather affecting the SR so that is not as quick as it should be to compensate. I would go out again and setup my camera on a tripod and disable SR.

I find that if I don't bundle up properly, the cold certainly affects my SR system.

At speeds like 1/125 second and normal focal lengths, you shouldn't really need SR unless you're shaking from the cold, in which case SR isn't really meant to counter that kind of shaking anyways. Concentrate on good technique and try a couple different solutions (SR on or off), and you should be able to find a way to get sharp pictures.

Yeah, I was going to say this.

In the cold, I find blurry pictures are often due to my own shivering and not any fault of the camera.
