I photograph events. In 2022 I moved from a pair of Nikon D4 cameras and lenses to Sony mirrorless and never looked back. The D4 is one of the best cameras Nikon ever made, but its 16 megapixel sensor size was becoming a problem. It was 10 years old and lacked eye focus, tracking features, higher ISO performance, etc. All the rose images here were taken with a D4.
