Why does FS700 sensor have 11.6 Megapixels?

Here's a question I've always wondered, why does the fs700 have an 11.6 Megapixel sensor when only 8.3 Megapixels is the effective area?
 
cool, thanks seanmc, so it uses a similar theory as the eva1 for oversampling I guess,

It's crazy to think the fs700 is now 5 years old lol
 
No, I don't think it's oversampling like that or a BM camera would. According to Alister Chapman (THE man when it comes to Sony video cameras) it's more likely wiggle room for digital image stabilization, coupled with CMOS "bumper" area.

It does have an electronic stabiliser and that probably does use some extra look around area, maybe 5 or 10%, but that still doesn’t account for the large discrepancy. You can’t just use a load of extra pixels beyond the super 35mm frame area as many lenses would no longer be suitable. It’s also not known whether this stabiliser will work at 4K, it may not as the camera will be bypassing the image processing in order to deliver a 4K raw image.

It’s actually very simple:

Sony don’t actually physically shift the sensor. That’s old school inferior technology that can lead to all kinds of issues.

Steadyshot = Optical image stabilisation, usually via a servo driven floating lens element within the lens.
Active steadyshot = pixel shift IS.
Super steadyshot = Optical IS + pixel shift IS.

The balanced optical Steadyshot is known as BOSS, where the lens and sensor are in a single gimbal mounted assembly.

CMOS sensors almost always have a pixel count and surface area greater than the active area. The extra pixels around the edge of the active area are masked and used for pixel noise sampling and signal biasing control.
