Design and Methods:
The goal here was to show the relative potential of these systems, hence I will present only RAW conversions and not in-camera JPEGs. There are many sites with excellent in-camera JPEG comparisons.
All images were made using Sony, Samsung, and Panasonic (14-45mm) kit zooms at f/5, which was chosen because it represents a setting of good center sharpness with adequate depth of field for all systems.
All kit zooms were used at their widest setting, and the subject distance was constant. The Panasonic lens at 14mm actually has a slightly wider angle of view than the Sony/Samsung at 18mm, but the reverse is true after Lightroom correction of barrel distortion. For practical purposes, the diagonal angle of view was fixed.
Since the purpose here was to look at sensor rather than lens performance, only center crops from the within sharp focus portion of the image were used for comparison.
To present a valid comparison of detail relative to noise at any given ISO, exposure times were matched for all systems as follows: 1) ISO 100: 2s; 2) ISO 200: 1s; 3) ISO 400: 1/4s; 4) ISO 800: 1/4s; ISO 1600: 1/8s; ISO 3200: 1/15s; ISO 6400: 1/30s. Lighting sources were kept constant.
Each shot was done in triplicate to ensure reproducibility.
All system settings were image stabilization off, self-timer, sturdy tripod.
