Electronic (OLED) Viewfinder on Olympus OM-D E-M5 Mark III

Olympus OM-D E-M5 Mark III has a built-in Electronic (OLED) viewfinder with 2,360k dot resolution. It has a 100% coverage and 1.37x (0.68x 35mm equivalent) magnification. There is no built-in or optional viewfinder available on Nikon Coolpix S9100.

Olympus OM-D E-M5 Mark III features a 20.4 megapixel Micro Four Thirds MOS sensor with dimensions of 17.4 x 13 mm and a total area of 226.2 mm². Its native ISO range is 200 - 25,600 and expands to 64 - 25,600 in boosted mode. Nikon Coolpix S9100 features a 12.1 megapixel 1/2.3-inch BSI-CMOS sensor with dimensions of 6.17 x 4.55 mm and a total area of 20.7 mm². Its native ISO range is 160 - 3,200.

Nikon Coolpix S9100 has BSI-CMOS sensor, short for Backside Illuminated Complementary Metal-Oxide-Semiconductor sensor. In traditional CMOS sensors, the wiring and circuitry are located on the front side of the sensor, which can block some of the incoming light. BSI technology flips this design by placing the photosensitive elements (pixels) on the backside of the sensor, allowing more light to reach the pixels. This significantly enhances light sensitivity and improves low-light performance. BSI-CMOS sensors are particularly effective in low-light conditions, as they can capture more light, resulting in brighter and less noisy images. This makes them well-suited for indoor and night photography. BSI-CMOS sensors deliver a higher SNR and reduced cross-talk.

Olympus OM-D E-M5 Mark III is equipped with TruePic VIII processor and can take pictures up to 5184 x 3888 resolution. Nikon Coolpix S9100 is equipped with Expeed C2 processor and can take pictures up to 4000 x 3000 resolution.
