[I'm not sure if this is the right forum, so please move if not]
I have spent the last few days using a Panasonic GH4.
This camera allows you to shoot video at 4k, [which equates to 24 x 8mp files a second, any of which you can extract from the video feed], so a 40 minute walk down your high street with indiscriminate shooting could give you up to c. 72,000 frames to choose from.
Cameras like this could herald a new era in documentary / street photography (although not necessarily for the better).
With more discriminate use, this technology could dramatically increase the yield of quality street photography - no more closed eyes..catching that decisive moment etc. The quality is also only going to get better with time.
I've written more at http://picabroad.com/panasonic-gh4-t...t-photography/
and will update this page as I get used to this very new and exciting technology.
Oh...and it's an excellent stills camera as well !
Below are a few examples of the video grabs from the camera and a couple of full sized jpegs are on the website.
