Manual Control Options
This D-425 is a point-and-shoot digital camera. It really doesn't have manual options. The biggest manual control it has is exposure compensation. Other than that, most of the menu options are simple camera setup controls. This camera is marketed as a low-end model for budget consumers; in this price range, it'll be hard to find any manual controls.

Auto Focus
The auto focus uses a contrast detection system. The Olympus D-425 can focus as close as 19.7 inches in the normal shooting mode and as close as 7.9 inches in macro mode. This isn't incredibly impressive. The focus in normal shooting range is about average, but the macro mode is insufficient.

Manual Focus
There is no manual focus on the D-425.

Metering
The D-425 uses a Digital ESP metering system.

Exposure
The Olympus D-425 does have one manual control - and it's the exposure compensation control. It can be adjusted from +2 to -2, which is common on compact digital cameras.

White Balance
The white balance system is activated through the lens and works automatically only. There are no manual adjustments, so the user must trust the camera's judgment of what true white looks like in different lighting situations.

ISO
The ISO cannot be manually adjusted, but the camera will automatically select a sensitivity rating between ISO 50-250 depending on the lighting. This range is a bit short, even for a $149 camera. Most compact digital cameras do not dip below the standard 50-400 ISO range.

Shutter Speed
The range of shutter speeds is as fast as 1/1500th of a second and as slow as _ second in normal shooting modes. In the Night Scene mode, the D-425 slows down to 2 seconds. These settings cannot be adjusted manually; all of it is done automatically by the D-425.

Aperture
The Olympus D-425 has a fixed 6.1mm lens with a fixed aperture of f/2.8.
