With the 3.0 software upgrade the image quality issues of the SONY HDR-AS30V in 120deg mode were greatly improved, for both with and without anti-shake! The image quality in 120deg mode is now almost as good as for the 170deg mode.
For software version 1.0/2.0:
In a previous post I wrote about the new SONY HDR-AS30V, Action Cam. In that post, which I have updated a couple of times, I mention that the image quality of the 120 degree wide angle setting of the Sony HDR-AS30V Action Cam is horrendous but the 170 degree wide angle setting is rather nice. This got me interested, why is the video in 120 so bad and the 170 not?
During my investigations I have also uncovered that:
- the time-lapse function is also affected by this, probably because it follows the video settings. This made it easier to test the issue since I didn't need to extract images from compressed mp4 files.
- the still images are always in 170, irregardless of what the "angle" setting of the camera is.
I don't really know how Sony have implemented the 120 degree setting but I believe it could be better. What I can see (but I know very little about image processing) the image sensor seems to have a lot to offer even for the 120 degree area. Perhaps they have made a mistake or perhaps they have a good reason for the current image quality. I just think it's sad that the 120 degree setting is as bad as it is and hope that Sony can fix it with a new firmware release.
If you have any idéas about this please leave a comment!
