Learn about the speed, image quality, and general performance tests we run on every digital camera and lens we review.
How We Test Digital Cameras and LensesIn the lab, we evaluate image quality across the entire ISO range to see how photos will look in varying levels of light and to determine whether lenses can deliver crisp images on modern, high-resolution sensors. With an interchangeable lens camera, we always use the highest-quality lens we have available at its best f-stop to evaluate noise and detail. We rely on an X-Rite Color Checker Classic swatch chart to obtain a quantitative noise value from out-of-camera JPGs, and we frame it next to a foreign bank note to allow qualitative analysis of noise and detail for both JPG and Raw images.bit.ly
