Slashcam have chart tested the A7S internal recording modes and the results for the regular frame rates 24-30p are incredibly positive. However it seems that in 60p the camera cannot utilise the full pixel readout of the sensor, which results in a worse image with moire and aliasing. You can read my take on this below or head over to Slashcam to read the original piece (Google translated)

DXOMark have tested the raw sensor output of the GH4. Raw stills have 12.8 stop dynamic range vs 11.7 stops on the 5D Mark III, illustrating just how far ahead almost everyone is on sensor performance over Canon.

Here Yosh Enatsu has used the Blackmagic HDMI to SDI Ultra HD converter to a Hyperdeck Studio deck to record this test shoot in the dead of night.

A big thanks to B&H Photo & Video in the US for shipping internationally a GH4 unit with no recording limits, I got it before it was even available in Europe. Delivery took just 2 days! Impressed! Also thanks to Susanna, the star of my video…

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…

As this impressive footage shows even though the camera is designed for general production rather…
