Olympus OM-4

The Olympus OM-4 is notable for its advanced multi-spot metering system, which allows photographers to take up to eight separate light readings from different areas of the frame. The camera's microprocessor then calculates the optimal exposure based on the average of these points, which is highly useful for complex street photography lighting.

The Olympus OM-4 uses the classic Olympus OM lens mount, which was standard for their 35mm film SLRs. While you cannot directly mount modern digital micro four-thirds lenses, you can use original OM-system Zuiko lenses, which are renowned for their exceptional optical quality.

Yes, the Olympus OM-4 relies on two silver oxide batteries (typically SR44 or equivalent) to power its electronic shutter and LED metering display. If the batteries die, the camera features a mechanical backup speed of 1/60th of a second, allowing you to continue shooting in emergencies.

The Olympus OM-4 offers significant upgrades over the OM-2, most notably the introduction of the multi-spot metering system and a durable, robust build quality. It also features a highly visible LCD display in the viewfinder, giving photographers more precise manual control over shutter speeds and exposure compensation.
