Re: The Spot AF Problem

In eye mode the pixel cluster varies, the exif shows it . If there are 44,761,088 pixels and there are 5,940 individual focus areas and if ALL the pixels are used, that suggests that each AF area has about 7535 pixels.

Alternatively a R5 36mm wide frame has 8192 pixels, so each pixel must be .0044 mm. Now if you use the 24mm width, and 5464, each pixel is.0043mm.

I imagine that is not so simple
