Lomo LC-A plus

The only automatic function offered by the LC-A is exposure. Film loading, winding, rewinding, and focus adjustments are accomplished manually. Aperture can also be set manually, the shutter speed being fixed at 1⁄60 s (this ability was removed from the LC-A+).^[3]

Exposure is completely automatic when the camera is set to "A"; the shutter speeds range from 2 minutes to 1⁄500 s. The aperture range is f/2.8 to f/16. The automatic exposure system compensates for changes in light levels after the shutter is opened by increasing or decreasing the shutter speed. This, in conjunction with the rear-curtain flash-sync, results in interesting effects with flash photography in low ambient light levels.^[3]

The lens is focused by selecting one of four zones (0.8 m, 1.5 m, 3 m or ∞). Older versions of the camera feature viewfinder icons showing the currently selected focus zone, a feature omitted from later models.

A battery checking feature uses a LED inside the viewfinder; if there is sufficient power this illuminates whenever the shutter release button is lightly depressed. Another viewfinder LED illuminates whenever the camera's chosen shutter speed is below 1⁄30 s.
