This aperture series look at performance of the Schneider Kreuznach LS 150mm f/2.8 on a sloping distance target, taking a total image quality perspective.
The 150/2.8 is an outstanding lens, but 150mm and this 3D scene is a practical demonstration of what realistic expectations for the 150 megapixel Phase One IQ4 when lens behavior and depth of field are both accounted for. While it’s not so easy to obtain full sharpness at this distance, excellent results can be obtained with care when focusing, as detailed here.
Includes images up to full 150MP camera resolution (14204 X 10652) from f/2.8 through f/8, plus crops.
