This latest photo album in the Camera On series is the first to cover an anti-aircraft weapon alone and whilst there have been a few books previously covering medium German 37mm Flak weapons, the 37 mm Flak 18/36/37 has never been covered in such photographic depth. This truly historically significant World War II weapon (along with the other German 37 mm weapons it evolved into) are illustrated in over 160 photographs. Nearly all of the images are from the author's collection that were originally taken by ordinary German soldiers not professional propagandists. The book shows this rarely illustrated equipment in detail but still shows it as the soldiers viewed it - as both their work place and in some cases also their home - not the highly posed and polished views of the official photographers.
