This shows what happens when a Nikon F2 is hit by an AK47 bullet. It’s one of the images in a major retrospective of the work of the war photographer Don McCullin, and is a pretty good testimonial to the build quality of the brand. There’s a vivid slideshow of some of the pictures from the exhibition here. Each one is unforgettable. McCullin is one of the age’s truly great photographers, but it’s impossible to avoid the impression that his life’s work has taken a terrible toll on him. He sometimes wears an inexpressibly sad expression.
