Performance Benchmark

Objectively characterizing the performance of a camera requires dozens of different metrics. While all of these are looked at by professional camera engineers, many are unnecessary for hobbyist component selection when a predetermined image sensor issued. For entry level camera engineering sake, we recommend starting with four first order system performance metrics: sharpness, color, shading and field of view. 

Resolution / Sharpness (sSFR)
