Avid amateur photographer Achim Mittler from Frankfurt, Germany, has been taking pictures for more than 50 years.

When he's not off on a "camera safari" photographing wildlife he puts a macro lens on his camera and captures beautiful images of flowers in his small backyard garden.

Mittler began his love of photography in 1966 with a Kodak Instamatic 25 film camera and worked his way up to a Mamiya ZE-X and Contax 159 mm. After taking a "break" from his hobby (all of his equipment was stolen) in the 90's, he returned to photography with digital cameras.
