I don't know why people keep comparing apples to oranges.
That's a stupid comparison.
I've compared a 2012 Panasonic video camera, top of the line, to my 2010 Pentax K-5. The K-5 wins hands down in everything but sharpness. Low light? Pentax is better (though it isn't particularly good). Dynamic range? No comparison, AT ALL. The Panasonic fails at scenes with little dynamic range, getting the colors wrong because of the lack of dynamic range.
Granted, that thing had a 1/6" sensor (3 of them, they are monochrome sensors). But I was still shocked by how bad it is.
The Sony has comparatively large sensor for a video camera, almost being reasonably sized already.
As to why the K-3 lost... a) settings perhaps, you can get a bit dynamic range by tweaking the image settings and b) The K-3 (and K-5) does a ton of line skipping. It may even only take 1080 lines out of the 4000 pixels there are. Granted, some of them would be lost anyway because of the different aspect ratio, but there are still roughly 3400 rows of pixels left when shooting 16:9... and it takes only 1/3 of them. It probably won't do any binning either with all the pixels in that row, so you can imagine how tiny the pixels that are actually used are going to be. Tiny pixels with a ton of space around them.
Modern DSLRs, for example ones by Nikon are significantly better. They tend to read all pixels within the 16:9 crop (the Samsung NX1 does, for example), and downsamples the image to the 2 MP Full HD image. That way you get huge pixels, and good dynamic range.
Originally posted by TER-OR If you want to take good video, get a videocamera. Some DSLR do OK for video - some are set up fairly well. None will be as good as a videocamera of the same cost. Use the right tool for the job. Sony does make some nice midrange videocameras.
Which is why Lauren is shooting corporate videos on bunch of K-3s. Which is why my company is shooting corporate videos (also for other international big name companies) using a 6D and a 600D. Because they suck compared to a consumer camcorder. Right.
Or why Mercedes Benz hired two videographers to shoot a video for their latest car using a Sony A7S II.

But yeah, these people and many more should have just used small consumer camcorders... right.
Btw.:
This is the Sony mentioned here vs the Panasonic that I've had access to... you can see how bad the dynamic range of the Panasonic is. Plenty of clipping pretty much everywhere. Just look at the skies, how the colors shift there because the sensor can't handle the "brightness". Plus that everything in focus look you get from small sensors.
