DV Info Net - RX100 Mk IV Impressions

First impression: Holy crap! This thing is amazing! ... with a couple caveats.

4k recording is limited. Not just in length (5 mins max) but also in frequency. I recorded two 5 minute videos at 1080/120p at 100mbps (which is an awesome format) followed by two sets of 5 minute 4k clips. By the second 4k clip the camera reported overheating about 2 minutes in and shut down 3 minutes in. However, even sony says those modes are time limited due to overheating... so it shouldn't be surprising that doing several of these in a row can cause a lot of heat.

But then there's the 240 fps HFR mode. Wow. With both start and end-trigger support, this is pretty much game changing. It supports up to 2 seconds (in best quality) high frame-rate recording and it looks amazing. This, combined with SLog2 support, picture profiles and the ability to do timelapses (an extra $9.99 app on the device... which I already owned because I bought it for the RX100 and the license works on both devices.) makes this a near perfect B-camera to my A7S or even a great stand-alone option while traveling. (I did use my RX100 Mk II for several TV shows as a B-Roll camera and it worked good...this will be a lot better.) I can definitely see myself setting this camera to go do a time-lapse by itself while I'm still shooting primary.

Yes, it's not cheap. Especially after adding a leather case (I ordered the Gariz case. The Sony Mk II case is slightly too large) and extra batteries. But nothing else I've seen can do what this tiny thing can do at the level with the quality it can do it.
