If we start at the top of the camera there are two features worth mentioning. OM SYSTEM has included an extra custom mode - five in total, compared with four on the OM-1 Mark II. This allows even greater flexibility and ease of access when programming settings. More importantly is the new dial on the left of the camera which allows you to quickly switch between shooting stills, video and slow and quick motion video. The S&Q Movie mode allows frame rates from 1fps up to 240fps.
As for the rear of the camera, one change that I truly appreciate is the location of the menu button. It is conveniently placed northwest of the OK button allowing easy access to the menu. As already mentioned the OM-3 has the same menu layout and design as the OM-1.
The OM-3 uses the same menu system as the OM-1 series of cameras.
The new CP button allows for easy access to the computational features within the OM-3.
While pressing the CP button the front and rear dials can be used to engage and adjust various computational features.
Each of the creative features allow for a fair number of adjustments. For example in MONO you can adjust the color filter effect, highlights and shadows, vignetting (referred to as Shading), sharpness, contrast, film grain effect (low, medium, high), and monochrome colour (normal, sepia, blue, purple, green).

I shot this old farmhouse in RAW, but also engaged the MONO1 profile which recorded a black and white jpeg image.
