Does anyone know if this "Natural" mode offers a slower shutter angle? Like 180-degrees?
Because the motion on every one of these Sony videos here is crushingly jerky from the fast shutter angle.
I get that they do that for a reason - because it catches fast motion with much less blur. But it makes regular motion look like crap and cutting that in with other cameras is very difficult...if not impossible.
Thanks.
As far as exposure goes, the only difference I noticed was that in "Natural" mode, the gain will max out at 24dB, whereas I see 30dB max in "Vivid".
The camera achieves automatic exposure by adjusting the shutter and gain. The slowest shutter is 1/30 and the fastest I've seen is 1/6000.
It "appears" the camera tries to maintain 180 degrees, but at some point it will speed it up or down from there. My testing wasn't controlled enough to say at what gain point the 180 degree shutter rule got violated (or "relaxed" if you prefer).
By making manual tweaks to the AE Shift (+2.0 to -2.0 in 13 steps), and while shooting a scene where the lighting was held constant, it was observed that the camera made adjustments to the shutter and gain to achieve the desired shift.
In average indoor fluorescent lighting, these values were noted: 2160 30P was 1/60, 2160 24P was 1/50, 1080 120P was 1/125.
Hope this helps and sorry if it came across as overly elementary.
BTW- I see there's a menu option where the choice is N (normal) or a symbol of a fish. Manual says to use the fish mode when shooting underwater. It notes that you cannot set the white balance if you choose the fish. So, sounds more like a white balance correction than fisheye fix. The scene I shot in N and fish mode looked the same to me, including the angle of straight edges. The lens doesn't suffer from severe fisheye.
