TechRadar say they use equipment and software supplied by DxO to do the testing. You'd think after a result like that they would stop and check their methods. Clearly some kind of operator error!

54 mentions of video vs 32 of photos in Nikon D810 press release
Andrew Reid replied to Andrew Reid's topic in Cameras
Interesting thanks. Unfortunately the interpretation of the SDK in that article is wrong. It is for software development on a PC for example, that interfaces with the camera. It will not allow custom software to run on the camera let alone custom firmware. The SDK has already been available for a wide range of other Nikon DSLRs so is not even new... https://sdk.nikonimaging.com/apply/ And thread here on Nikon Hacker is worth a read https://nikonhacker.com/viewtopic.php?f=4&t=2096 -
Yeah 24p on this camera is in a faux cinema aspect ratio with the crop forced on you in-camera, 1920 x 810. 30p otherwise. Nothing about the image is better than the G6 and the codec is FAR worse so beware!

Nope. Please read the patent for the answer. "Hayato Wakabayashi proposes to read 4 rows simultaneously, while keeping a smooth progression of the rolling shutter" The ramp DACs 142 and 152 work with a delay to have a smooth shutter curtain advance http://image-sensors-world.blogspot.de/2014/07/faster-readouts-smaller-rolling-shutter.html

Yes PC displays have different gamma setting to the Mac default, but they should read the gamma from the file and show it correctly, having said that this is Windows we're talking about... :wacko: I much prefer James' original grade to the one posted later by someone on the forum, the elevated blacks are really silky and film-like.

The A7S is so close to being a 'complete' system for high end video quality in a small prosumer camera, but there's one issue that has quite rightly been highlighted by filmmakers such as Andrew Wonder and that is the rolling shutter distortion. The A7S actually has a very fast sensor with high efficiency made possible by the latest technology but because it does not skip any lines when reading out the image the net result is a scan that takes roughly as long as the older 5D Mark II, which does line-skip. Sony plan to fix this by introducing a new sensor technology which can read entire lines of pixels in batches of 4 simultaneously. Read the full article here

Hell, get an Easyjet flight to pick it up! Still ends up much cheaper :) The DigitalRev euros price ends up similar to the European retail RRP at stores in Germany, but their GBP price is cheaper. Go figure :)

Yep almost all ways apart from the rolling shutter, which is a result of having the full pixel read out, so worth it in my view. There's always the APS-C mode & IS for more violent handheld work. In future Sony plan to read 4 lines at once on their CMOS sensors to speed up the full pixel readout. They have filed a patent for it. Miles ahead of Canon? Looking like it.

Picture courtesy of James Miller, inset - the CYP 4K HDMI scaler The picture above (click for 1080p original) is from the 4K full frame sensor inside the Sony A7S (ISO 3200, S-LOG2). Internally the camera does a simple downscale of the 4K signal to 2K for standard 1080p XAVC or HDMI recording - but James discovered adding a hardware scaler on the end of the 4K HDMI signal results in a more detailed 1080p image which is light and day different. The great news is this scaler is only £167 in the UK. Add to that an Atomos Ninja Blade or Ninja Star for taking the image from the scaler and recording it to ProRes - and you have one of the best 1080p images available at any price.

Yes it has arrived in the UK without a hitch, quick delivery. Only problem is I am in Berlin! :)

Thanks Stephen!
