Longer exposures tend to help since they push pixels to a higher temperature. It's super simple and takes like 10 seconds to check. Make sure you shoot Jpeg in camera because most RAW converters remove hot pixels, which makes it a total non-issue.
I really feel this is another DPR making an issue out of nothing. I've lost all faith in their reviews since they don't print images, they just look at them on monitors which never tells you the quality of the camera and the images it takes.
Hey Chris, I find I either strongly agree or disagree with you... not a lot of middle ground. And usually it is agree. But here I am confused.
Have I misunderstood the issue? I thought it was looking like a 'live view' issue. Which of course could be related to temperature too, but not the same way long exposures are. In long exposures the cameras do a Dark frame subtraction to deal with hot pixels for the increased sensor temps. In a live view mode, isn't the sensor is always on? But the pics you take may be at very fast shutterspeed and not subjected to DFS. So if the sensor is getting too hot during live view that may be what is happening. So just taking long exposure test shots will do little if it is a live view issue.
But where I disagree is about DPR
About them making an issue out of nothing. If they have two copies experiencing some issues, how is that nothing? Do you honestly think they are making it up?
Can you link me to other instances where they made something up of nothing? My experience only goes back a few years, but I think the times they have sent cameras back to mfgr's in the middle of a review there were real problems that did exist.
As far as DPR only looking at monitors and not printing the images. Do you really want to bring all the variables of printers/inks/paper into the mix? The complex cameras of today have enough variables for them to address IMO.
I am as confused as anyone as to what they are seeing, that the majority of K20 owners here are not. But I don't think they are making it up.
Maybe I am reading you wrong here... Which I have be guilty of in the past.
If so, my apologies and feel free to fire away...
