The Olympus OM40 is an SLR film camera with a 50 mm lens attachment. This manual focus camera features an amply sized viewfinder so users can make necessary changes in a quicker manner. This Olympus 35 mm camera offers controls that are scaled for ease of use and are placed in a properly organised fashion. In addition, the Olympus OM40 uses the T-series flash devices, which mount easily to the top of the camera. The addition of this type of flash allows the user of the SLR film camera to set the aperture specifically for the task at hand. If the flash is set closer to the object being photographed, the photo will come out clearer and brighter. A key feature on this Olympus 35 mm camera is the ability to shoot with motor drive. Using this function allows the user to shoot motion, such as sports photos, while remaining still. Additionally, this particular Olympus 35 mm camera works great for macrophotography, has a light metering system, and promotes ESP metering.
