Holga 135BC — plastic 35mm toy camera with a built-in Black-Corners vignetting mask
Holga began in Hong Kong in the early 1980s as a cheap medium-format camera for the domestic Chinese market, before its plastic-lens, light-leaking aesthetic was adopted by lo-fi photographers worldwide. The 135BC adapts that toy-camera formula to 35mm film, part of the 135 series launched around 2005.
It uses a plastic 47mm lens with a two-position aperture, f/8 or f/11, and a fixed shutter speed of around 1/100 second, focused via a zone ring with presets for close, medium and distant subjects. The 'BC' feature is a built-in mask creating strong vignetting and darkened corners on every frame. It has a hot shoe but no meter or autofocus.
The plastic lens and mask are the whole point: images come out soft, unevenly exposed and heavily vignetted with the Black Corners effect, a rough look manufactured 'correct' cameras avoid. This makes every shot visually distinct from a standard Holga 135 frame lacking that signature.
These are inexpensive, mass-produced plastic cameras, so buyers should mainly check the light seals are intact, since light leaks beyond the intended vignetting are a common fault, and that the film advance and shutter fire reliably.
