This test of thecamera namecamera and lens was conducted usingDxO Analyzer. If you are not familiar with this optical testing system please readthis tutorial. Without being familiar with how the tests are conducted, and how to read them, there’s not much point in proceeding.
The purpose of this test report is to support the empirical findings of my field test of this system. Though the tests on this page are interesting and informative (as well as accurate and repeatable), they really only tell us about selected aspects of a camera or lens’ capabilities.
About The Tests
As you can see from theDxO Tutorialthere are a large number of charts and text graphs produced for each of the four tests —Distortion & Chromatic Aberration,Vignetting,NoiseandBlur. A more comprehensive test would have to be done at all available apertures, all available ISO speeds, and at a large cross-section of focal lengths (in the case of zoom lenses). This would not only take an inordinately large amount of time to conduct, but would take up far to much space here and likely not be of much interest.
Consequently in this and other tests usingDxO AnalyzerI am publishing just one complete set of charts — those done at f/5.6, which is typically an optimum aperture for most lenses. In the case of zoom lenses this test is also done at a mid-position in the lens’ focal length range. I also post data for other F stops, ISO ratings and in the case of zooms a selection of focal length, including the widest and longest. In my comments to each section I also draw attention to extremes of performance, such as maximum vignetting, greatest and least noise, etc.
