>>4305713>that is not what your image shows, those lines are far thicker than 1 pixel and spaced further apart then 12.Are you actually retarded or is this a joke?
Look at this image.
The 1px black lines are the PDAF rows
the white spaces are 11 non-pdaf rows between the PDAF ones
What's in your image here is the AF zones.. each zone included an area with multiple pdaf stripes within it.. that's how AF zones work 273 pdaf points doesn't mean 273 pdaf photosites
pdaf requires many photosites per AF point to operate, and they're built into rows of the sensor (but not every single photosite in the row is a PDAF one)
