    On the p4k, which already eats batteries like crazy, I'm using the included BM and some RavPower LPE6 batteries, and they seem to last the same. I haven't...

    The current compression rate in the r5 seems to be around 4:1 (scaled from the 6k figures of the p6k to the 8k sensor in the r5). So, there's some good compression there already. If they take it all...

    Bigger sensors are waaaaay slower than small sensors. Making a bigger version of a similar design completely screws the thermal budget, and if you don't make it run a lot slower you have to put a...

    And loads of phones too. But that's all pretty recent: for the first six or eight years of its life, H.265 wasn't used at all, and one of the big reasons was the licensing mess.

    That Sony interview sounds really bad to me: they are aiming to match the specs of the S1H (4k 60fps 422 10-bit internal, still working on raw which is probably external), and they're coming out one...

    ARM CPUs are great in terms of performance-per-watt but not so much in terms of just performance, so I guess this is good for the Macbook Air, has pros and cons for the Macbook Pro, and is bad for...

    Sometimes ADC bit depth matters a lot for dynamic range, sometimes it doesn't. Dpreview often checks this:

    This is just a Sony RX100V with mic in and a screen that folds to the side instead of up (where a hot shoe mic would block it). It's not a bad camera by any means, I still have my RX100IV (which is...
