OM-3 vs OM-5 Mark II Specs
Sensor Resolution
The OM System OM-3 uses a 20MP stacked BSI Live MOS sensor. This design delivers sharp resolution with minimal noise and vivid colors.

Image Stabilization
Both cameras provide robust in-body image stabilization for handheld shooting. The OM-3 offers up to 7.5 EV steps of compensation. This allows you to capture city streets or wildlife with ease. The OM-5 Mark II provides 6.5 stops of stabilization on its own. However, it reaches 7.5 stops when paired with compatible Sync IS lenses. If you use standard lenses, the OM-3 has a slight advantage.

The 14-150mm covers a wider range. You should choose based on whether you need wide-angle versatility or long-range reach for your subjects.
Autofocus System

The data for the OM-3 does not list its specific autofocus point count or phase-detection capabilities. It mentions dust reduction and sensor features but omits detailed AF specs. You may need to check other sources for the OM-3's exact AF performance. The OM-5 has a clear advantage in listed autofocus technology.
Creative Features

The OM-3 features Live ND and Live GND filters for long exposure shots in daylight. It also includes a Graduated Neutral Density filter for precise positioning. Both cameras support creative techniques. The OM-5 offers more variety in computational tools. The OM-3 excels in neutral density filtration. You should choose based on whether you prefer focus stacking or long exposure filters.
