04.07.2015 - In April 2015 I had the great pleasure to be hired by Nikon to do the official BETA-testing of the new Nikon 600mm f/4.0E FL ED VR for 10 days in South Africa. A total number of 10.600 images were shot with the BETA 600mm lens during the assignment. All images were exposed with a Nikon D4S camera, and most of the images were shoot with aperture between f/5.6 – f/8.0 and ISO 100 – 3200 to achieve best image quality.
