Sony Alpha SLT-A99 II features a 42.4 megapixel Full Frame BSI-CMOS sensor with dimensions of 35.9 x 24 mm and a total area of 861.6 mm². Its native ISO range is 100 - 25,600 and expands to 50 - 102,400 in boosted mode. Fujifilm X-T10 features a 16.3 megapixel APS-C CMOS X-TRANS II sensor with dimensions of 23.6 x 15.6 mm and a total area of 243.4 mm². Its native ISO range is 100 - 51,000.

Sony Alpha SLT-A99 II 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 SLT-A99 II is equipped with BIONZ X processor and can take pictures up to 7952 x 5304 resolution. Fujifilm X-T10 is equipped with EXR Processor II processor and can take pictures up to 4896 x 3264 resolution.

Lens Mount

Sony Alpha SLT-A99 II has Sony A lens mount and Fujifilm X-T10 has Fujifilm X lens mount. Due to Full Frame sensor in Sony Alpha SLT-A99 II 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 Fujifilm X-T10 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.

No Low-Pass Filter on Sony Alpha SLT-A99 II

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Sony Alpha SLT-A99 II. This results in a slightly sharper image but may also introduce moiré patterns and aliasing artifacts when photographing subjects with fine, repetitive patterns or details.

In-Body Image Stabilization on Sony Alpha SLT-A99 II

Sony Alpha SLT-A99 II has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS). This means that you are still getting vibration reduction when camera is 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

Cameras have built-in Wi-Fi (802.11b/g/n, 2.4 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.
