Top 6 videos on EOS R with combined 2 million views and not a single mention of the rolling shutter in 4K

Comment on the forum

With an increasing number of customers relying on YouTube for expert consumer advice, is it any wonder Canon continue to sell more cameras than Sony and Panasonic?

Sony A6300 review (rolling) – Striking image but nagging issues

Welcome to my rolling review of the Sony A6300. Like the rolling shutter of the A6300 this review takes a long time to get from the top to the bottom so grab a hot drink (be careful not to overheat) and enjoy the ride…

Sony A7S with Atomos Ninja Star

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.

Good news! Super 35mm mode on Sony A7S dramatically reduces rolling shutter

All footage by Ed David on the EOSHD forum

I’m surprised at how nice the quality is from APS-C (Super 35mm) mode on the A7S. I expected it to be a lot softer! There’s no signs of significant moire or aliasing either.

The smaller window from the sensor allows the shutter to expose the whole pixel readout more quickly than in full frame 12MP mode, so less jello for us.

Panasonic GH4 – Slow-mo at 96fps and 4K rolling shutter test

All tests based on pre-production model

Here we come to some areas which aren’t perfect on the GH4, but which nevertheless are both a step forward from the GH3. I like what Panasonic have started here with 96fps slow-mo. This is the first consumer camera to deviate from the video standard of 60p to give us a genuinely useful creative tool which sets the ball rolling for improvements in future models.

Sony AX100 4K video camera – how much rolling shutter is too much?

The Sony AX100 takes the relatively large 1″ sensor from the RX10 and puts it in camcorder form factor with built in ND filter. However it appears that in reading out all the pixels on a 20MP sensor, Sony have created a skew-monster in rolling shutter teams. What’s remarkable about this video is that the panning and trains aren’t even moving very fast. This is some of the worst rolling shutter I’ve yet to see on any camera available on the market.
