Minimum ISO (Native)
Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image.
Maximum ISO (Native)
Refers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise.
Minimum ISO (Expanded)
Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.
Maximum ISO (Expanded)
Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.
Minimum Shutter Speed
The minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory.
30 s

Sony SLT Alpha 57 Features and Benefits

The Sony SLT Alpha 57 receives a feature score of 41 out of 100. This score reflects the camera’s available features, which include a 3-inch screen with a resolution of 921,000 dots. However, it lacks a touchscreen, GPS, WiFi, and Bluetooth capabilities.

In the current camera market, a 3-inch screen with 921,000 dots resolution is relatively standard. The absence of a touchscreen may disappoint some users, as touch functionality has become more common in recent cameras. The flip screen offers versatility in shooting angles, but the lack of GPS, WiFi, and Bluetooth makes sharing and geotagging photos more challenging.

Considering these specifications, the Sony SLT Alpha 57 falls short in the features department compared to its competitors. While the flip screen is a positive aspect, the lack of connectivity options and a touchscreen limits its appeal to modern photographers.
