k-7: dark horizontal lines live view? bad sensor?
So after recording video for a long time on a hot night I noticed that the video I was recording had a dark line at the bottom of the frame. Live view has the same issue. Granted it was night and it was probably max iso and I was getting the temperature warning, but I've never noticed this until now. When the sensor is hot shooting at 3200 is quite noise with lots of horizontal banding, but it seems well controlled @ 1600 and disappears @ 800. Should. I really worry? Does anyone elses live view have darker areas @ high iso in low light? I've heard that banding and noise issues were common in k-7's sensor in low light anyways. I'm just kind of worried my sensor is dying now or something. I couldn't tell you how many clicks I've rang up...30k or so? I'll have to look for this in better light. Just a little worried now.....
