Sony have admitted problems with the FS5
Finally we get the answer from Sony engineers on the problems seen with some FS5 users, here is the statement from Sony…
‘Sony has investigated the PXW-FS5 image artifact issues reported by users. Our engineers have been able to duplicate these issues and identify their root cause. Sony plans to provide a firmware update. Our goal is to issue this revised firmware toward February/end.
To ensure that users achieve the best results from the FS5, Sony is also preparing guidelines to help professional shooters take full advantage of the FS5’s features, including S-Log and S-Gamut’.
Here is Alistair Chapman’s take on Sony’s news…
My understanding is that this primarily relates to the edge tearing issue as well as the blocking type artefacts that can be seen, particularly at higher gain levels. It’s great to see solid proof that Sony do listen to us. They always have done, but often simply went away and investigated and fixed the issue without actually saying anything.
It does still need to be remembered that in UHD the camera is an 8 bit camera and this firmware update will not change that. Nor will it change the recording bit rate. I also do not expect to see a change of the cameras base ISO, so don’t expect to see any significant difference to the cameras noise levels. So while I am sure the firmware will bring a useful and welcome improvement to the image quality, you will still need to be careful how you shoot with the camera, especially in low light or with S-log in UHD. The user guides that are being prepared will hopefully address these areas.
