23.6 sensor is too big for 1/2.3-inch matrix.

[ New ]

Why did you ruin 4K video quality?
It is impossible to watch and the pixel display quality has become terrible with this sensor size.

GoPro 7 shoots better than version 9 and Hypersmooth 1 is more better than Hypersmooth 3

I can't use Hypersmooth 3 at the 3PM, because it LOW LIGHT scenario for it.

Are you OK to drop this product to market?

The sensor is a Sony IMX 677. Works worse in low luminosity conditions. More megapixels doesn't give better picture. A 1' sensor would be better for capturing more light

hi,

yes...true

I want a better low light sensor myself, but I think is not possible on an action camera.

 

a bigger sensor at the same resolution means bigger physical pixels.

a bigger pixel has a better signal/noise ratio, meaning you cane use higher ISO without noisy image.

the same surface more resolution means smaller pixels.

 

but! I feel the ISO3200 is usable, at least for me, at the limit.

in gopro 7,8 the max I used was 1600.

 

so I think even smaller pixels, behave better at higher ISO.

 

my feeling is:

  • the 5K sensor was introduced for stabilization, to have enough room on the sensor surface to stabilize a 4K
  • gopro wanted to preserve the wide FOV we all love
  • sensor technology and software can balance t some extend the sensor smallness...

in order to have a 1" sensor and the same FOV, the optics should be much larger.

look at the Sony RX0, has a 1" sensor but half the FOV and slower lens f/4 (GoPro has f/2.8)

neither helps Sony to get better images in low light.

 

somewhere you have to do a balance.

 

personally, I want a 35mm sensor on a camera - but the lens will be as a DSLR one... so no more action camera.

 

just me,

robert

Then ISO 800 loses a lot of quality. For me the example is the Insta One R 1' with F3.2 but from what I have seen, it works better in low luminosity conditions. It must be because of the size of the pixels

I agree, but now, i don't like video quality even in sunlight

I hope the image has software solution
