Optical Physics Bottleneck Assessment
At f/1.68 with 1.20μm pixel pitch, the optical Airy diffraction spot (2.25μm) spans roughly 1.88 physical pixels. Increasing megapixel count further yields diminished sharpness returns because resolution is optical diffraction-limited, forcing reliance on multi-frame computational pipelines.
