Beyond Megapixels: What Really Determines Camera Lens Resolution
This article explains that megapixels alone do not determine image quality. Optical resolution, measured by MTF, edge performance, and aberration control, is equally critical. Sensor pixel pitch and lens matching affect real detail capture. A lens may resolve fine lines at the center but soften at e......

MTF Testing Explained: How Engineers Evaluate Lens Performance
MTF (Modulation Transfer Function) testing measures how well a lens transfers contrast and detail to the sensor, revealing true optical resolution beyond megapixel counts. Engineers evaluate center, edge, and mid-field performance using controlled patterns. MTF curves show contrast retention at fine......
