Hero 7 Image Sensor

Anyone aware of the actual specs for this, specifically in stops; what's the dynamic range of the Hero 7 Black's sensor?
I can't find any meaningful tech data anywhere.

 

TIA

Hi @spazwinchester

 

Unfortunately, we don't have that information regarding the sensor capability.

 

 

Thanks!

Re: Hero 7 Image Sensor

“We”? So GoPro don’t know the specs of the image processor in their own gear? That’s hardly reassuring.

Re: Hero 7 Image Sensor

Useful dynamic range is much more complex that a simple number, if that is what you were hoping to hear.   

 

Such as XX F-Stops.  

 

To then compare to some other device with a similar claim.

Re: Hero 7 Image Sensor

I don’t think it’s unreasonable to expect a hardware manufacturer to know exactly what the EV range of a camera sensor is. It’s stsndard practice to one, specify those needs before the sensor is commissioned and two, test it against said requirements. It’s quite naive to believe otherwise. That’s why DXOMARK is so useful. They’ve even tested older Hero cameras (and they don’t perform that wel)l.
As a potential customer with a legitimate enquiry about the new cameras capabilities I’d expect someone to have hands on those specs. To claim not to know at all is frankly ridiculous imo.

Re: Hero 7 Image Sensor

@spazwinchester - I guess it's  the same Sony sensor as in the Hero6.

 

This is called Sony IMX277.

"12MP 44fps max @ full res, 1/2.3, 1.55 pixel size, SLVS-EC 8Lane" BI, DOL-HDR

 

BI DOL-HDR = Back-illuminated CMOS Image Sensor Digital Over-Lap High Dynamic Range technology

In the pas the Sony SONY IMX117 sensor was found in the Hero3, 3+, 4 and 5!
