This feature can be helpful for achieving precise focus in both photo and video recording.

BSI-CMOS Sensor

Sony FX3 features a 10.2 megapixel Full Frame BSI-CMOS sensor with dimensions of 35.6 x 23.8 mm and a total area of 847.3 mm². Its native ISO range is 80 - 102,400 and expands to 50 - 409,600 in boosted mode. Pentax Optio WG-2 features a 16 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 125 - 6,400.

The cameras have 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.

Sony FX3 is equipped with BIONZ XR processor and can take pictures up to 4240 x 2832 resolution. Pentax Optio WG-2 can take pictures up to 4288 x 3216 resolution. It can also take pictures with lower resolution like 4288 x 3216, 4224 x 2376, 3216 x 3216, 3072 x 2304, 3072 x 1728, 2592 x 1944, 2592 x 1464, 2048 x 1536, 1920 x 1080, 1024 x 768, 640 x 480 with 1:1, 4:3, 16:9 aspect ratios.
