Portrait lens reviews (WYSIWYG)
With a portrait lens you make a full screen, natural looking portrait. In addition, you want to have a limited depth of field in portraits. The blurry background ensures that the subject gets all the attention. On a camera with a full frame sensor is a focal length between 85 and 135 m, and a brightness of f/2.8 or better suitable.
The performance of the lenses in this table are based on " What you see is what you get ( WYSIWYG )", as you save images in the camera as a jpg file, with all the in- camera lens corrections applied ("What you see is what you get ": WYSIWYG"). If a lens is tested on a camera with an APS-C or micro-43 sensor , then the focal lengths have been converted to the equivalent field of view for a camera with a full frame sensor ( mm @ ff ) . Because of this conversion, you can compare lenses on cameras with different sensor types . There are scores for sharpness (Res), chromatic aberration (CA) , vignetting (Vign) and distortion (Dist). The higher the score , the better the performance. The highest score is a 9.9 . Note thet lens scores are determined by the test camera being used (megapixels , sensor size, jpg conversion).
Pure & RAW
There is another, " Pure and RAW" table with test results based on raw test results , where no corrections for chromatic aberration , distortion or vignetting have been applied. Also the influence of the jpg conversion and sharpening are ruled out. RAW files withou sharpening are used for the Pure and RAW table. These scores approach the intrinsic quality of the combination of lens and test camera.
