Fancy turning your expensive digital SLR into a toy camera worth US$25? Now you can.

We'll be the first to admit that the lo-fi aesthetics of Holga and lomography cameras are exactly what the doctor ordered when surrounded by the near-perfection of testing modern lenses. Light leaks, vignetting and hyper-real colours are all characteristics of these lo-fi Holga plastic lenses.

Lomography devotees will already be aware that you can mount certain Diana lenses on your SLR. Holga Direct sells a range of Holga lenses using different mounts (Canon, Nikon, Olympus, Pentax and Sony) for your SLR, and have recently expanded into dedicated lenses for interchangeable lens cameras. The store now has lenses for Panasonic's G series, the Olympus Pen cameras, Sony's NEX mount and the Samsung NX cameras.

Plus, if true lo-fi is your domain, they even sell the real deal.
