This picture was taken in the middle of a frozen lake, shortly after midnight on January 1, 2013, using my blue Pentax K30 and the DA 18-55 WR. A tripod was used so I could use the camera timer and get myself into the picture (far left). I don't have a flash, and the onboard flash would have ruined the picture, so we laid our headlamps down in the snow and pointed them up to illuminate us.
The temperature was -12 celsius. The camera buttons were sticky, and the camera itself was responding kind of sluggishly, I'm assuming from the cold. Nevertheless, it powered through and helped deliver one of my first shots of 2013.
The K30 performed admirably during the entire two days I spent in the frozen wilderness. I could not be happier with my camera!
