High-Resolution Mirrorless Cameras: Low-Light Performance and Image Quality Score

A professional photograph taken in extreme low light captured with a 60MP mirrorless camera

1. Defining the High-Resolution Low-Light Advantage The modern high-resolution mirrorless camera (typified by sensors from 45MP to 100MP) presents a dual challenge: maximizing pixel count for detail while simultaneously maintaining acceptable low-light performance (minimal noise). Historically, high resolution meant small photosites and increased noise. Contemporary sensor architectures—specifically Back-Illuminated (BSI) and Stacked CMOS designs—have largely resolved … Read more
