Individually optimized on-chip lens positioning
Gapless, optimally positioned
on-chip lenses (a7R)
Sony optimized the design and positioning of
every on-chip lens (OCL) covering every pixel to
significantly enhance light-gathering efficiency.
This raises sensitivity while maintaining low noise
and achieving an impressive S/N ratio. A gapless
on-chip lens design eliminates the gaps between
micro-lenses to collect more light. Moreover, each
on-chip lens is optimally positioned depending on
its location to accommodate the sharper angle
of light entering the periphery, which is caused by
larger sensor dimensions being teamed with the
E-mount's short flange-back distance.

Advances in sensor technology
The exceptional performance and sensitivity of the
image sensor is achieved with the help of three
advances in sensor design. Light concentration
technology compressed the height of circuitry to
dramatically increase the amount of light collected
by each pixel. Photodiode expansion technology
increases the size of the photodiode at every pixel
to improve the sensor's dynamic range and deliver
smoother, richer image gradation. On-chip column
