Produced at first in 1982 in Hong-Kong, Holga is made according the same philosophy as Diana. Box and Lens are both made in plastic. Holga is made for 120 films for a square, or 6x6, format. The cheap and unegal lens do not allow you to have a whole sharp image. Every lens is unique so every Holga produce personal image.
The closing system is also quite uncertain. The film can sometimes be accidently exposed. Holga is easy to adapt too. You can easily use a 135 film. It is also possible to do special panoramic picture, the Holgaroma.
Now produced by the Lomographic Society International, Holga is a fun way to begin with lomography and square format.
