strobing and flickering is increased in PAL, when shooting 1/25s with various in-door lighting. Check out:

The tester claims that "1/50 always looks best.
1/100 works most of the time & 1/30 can help in low light.

1/200 and faster divides of 1/50 do not look good at all as you can check in the video.

any other setting is calling for trouble in most places with ordinary 50Hz AC lights."

When testing the NEX I noticed flickering in certain circumstances, but since there is no way to control shutter speed, it is a matter of chance; sadly;

As I have tried to explain, you can control shutter speed in most conditions.

A Photo shutterspeed of 1/60s gives a video shutterspeed of 1/60 or 1/100.
If you know how to do it you can record video at 1/100s.

1/60s (photo) = 1/60 or 1/100s (video) = perfect video at 1/100s
1/100s (photo) = 1/150 (video) = banding problems

Recording under 50Hz lighting you will not get major problem keeping video shutterspeed under 1/50s or at 1/100s.

The video algorithm keeps a faster shutter speed than photo so you will get a darker video than photo at the same ISO and same aperture.
