I had no idea there were so many varieties of tanks in the world. I looked at lots in the Bovington Tank Museum but found the shapes and patterns of more interest, especially using the 12mm lens - wonderful shapes of the architecture too. There was a mock battle display outside with interesting and well presented details of the tanks used. Even I found it absorbing! For these I used a 105 mm lens, not having a zoom with me.
I can't believe the week is almost over and tomorrow it's time to head home.
