Electronic (OLED) Viewfinder on Sony Alpha 7C

Sony Alpha 7C has a built-in 0.39" Electronic (OLED) viewfinder with 2,359k dot resolution. It has a 100% coverage and 0.59x magnification. There is no built-in or optional viewfinder available on Pentax K-01.

Sony Alpha 7C features a 24.2 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 100 - 51,200 and expands to 50 - 204,800 in boosted mode. Pentax K-01 features a 16 megapixel APS-C CMOS sensor with dimensions of 23.7 x 15.7 mm and a total area of 246.5 mm². Its native ISO range is 100 - 12,800 and expands to 100 - 25,600 in boosted mode.

Sony Alpha 7C 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.

Sony Alpha 7C is equipped with BIONZ X processor and can take pictures up to 6000 x 4000 resolution. Pentax K-01 can take pictures up to 4928 x 3264 resolution. It can also take pictures with lower resolution like 4352 x 3264, 4224 x 2816, 4928 x 2776, 4224 x 2376, 3840 x 2880, 3456 x 2304, 3456x1944, 3264 x 3264, 3072 x 2304, 2880 x 2880, 2688 x 1792, 2688 x 1512, 2304 x 2304, 2304 x 1728, 1728 x 1728 with 1:1, 4:3, 3:2, 16:9 aspect ratios.

Lens Mount

Sony Alpha 7C has Sony E lens mount and Pentax K-01 has Pentax K_AF2 lens mount. Due to Full Frame sensor in Sony Alpha 7C its crop factor is equal to 1x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length. Due to APS-C sensor in Pentax K-01 its crop factor is equal to 1.5x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.5.

In-Body Image Stabilization

The cameras have a built-in in-body image stabilization (IBIS) (5 stops of compensation in Sony Alpha 7C). This means that you are still getting vibration reduction when cameras are paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.

Built-in Wi-Fi on Sony Alpha 7C

Sony Alpha 7C has a built-in Wi-Fi (Wi-Fi 5, 802.11ac/b/g/n, 2.4/5 GHz) which allows to easily transfer photos and videos from the camera to other Wi-Fi-enabled devices, such as smartphones, tablets, printers, or computers. This eliminates the need for cables and allows for quick and convenient media sharing and social media integration. It gives you the ability to control your camera remotely using a smartphone or tablet. This is particularly useful for taking self-portraits, group shots, or capturing images in challenging conditions without having to touch the camera. Firmware updates can also be downloaded and installed wirelessly.
