Camera classification based on autofocus system
Phase-detection autofocus (PDAF) is a popular autofocus system used in cameras to accurately and quickly focus on a subject. This system uses a sensor to detect the phase shift in the light that passes through the lens and reaches the sensor. The phase shift occurs when the light waves change direction as they pass through the lens, which is caused by the difference in refractive index between the air and the lens material.
Digital Single-Lens Reflex (DSLR) cameras use PDAF to provide fast and accurate autofocus. In a DSLR camera, the light enters the lens and is directed to a mirror that reflects it upwards to an optical viewfinder. The mirror also directs a portion of the light to a PDAF sensor located beside the image sensor. The PDAF sensor detects the phase shift in the light and sends the focus information to the camera’s focusing motor, which adjusts the lens to achieve sharp focus.
Mirrorless cameras do not have a mirror or an optical viewfinder, and instead, use an electronic viewfinder (EVF) or the rear LCD screen to preview the image. The light entering the lens is directed to an image sensor that also acts as a PDAF sensor. The PDAF sensor detects the phase shift in the light and sends the focus information to the camera’s focusing motor, which adjusts the lens to achieve sharp focus. Mirrorless cameras with PDAF can focus quickly and accurately, making them ideal for action and sports photography.
Contrast-detection autofocus is a type of autofocus system used in cameras that focuses on the contrast of the image. This system is commonly found in DSLRs and mirrorless cameras.
In DSLRs, contrast-detection autofocus is typically used as a secondary autofocus system. It works by analyzing the contrast of the image and adjusting the focus accordingly. This system is particularly useful in low-light situations where the primary autofocus system may not work as effectively.
In mirrorless cameras, contrast-detection autofocus is the primary autofocus system. This system uses a sensor to analyze the contrast of the image and adjust the focus accordingly. Mirrorless cameras often have a hybrid autofocus system that combines both contrast-detection and phase-detection autofocus. This hybrid system provides faster and more accurate autofocus performance.
Overall, contrast-detection autofocus is a versatile autofocus system that is commonly used in DSLRs and mirrorless cameras. It provides fast and accurate autofocus performance, making it a popular choice for photographers.
On-sensor autofocus (OSAF) is a type of autofocus system used in mirrorless cameras. It is called “on-sensor” because the autofocus system is built into the camera sensor itself. This means that the autofocus system can analyze more of the image at once, making it faster and more accurate than other types of autofocus systems.
In mirrorless cameras, the image sensor is smaller than the image sensor in a DSLR camera. This means that the autofocus system has to work harder to focus on the subject, as there is less distance between the autofocus points and the image sensor. However, because the autofocus system is built into the sensor itself, it can work much more quickly and accurately than other types of autofocus systems.
One of the benefits of on-sensor autofocus is that it allows for faster and more accurate autofocus in video recording. This is because the autofocus system can continuously analyze the image while recording, making it easier to keep the subject in focus. Additionally, on-sensor autofocus systems are generally quieter than other types of autofocus systems, making them ideal for use in situations where silence is important, such as during video recording or in live performances.
Another benefit of on-sensor autofocus is that it allows for more accurate autofocus in low-light conditions. This is because the autofocus system can analyze the image more accurately, even in low light conditions. This makes it easier to take high-quality photos in dimly lit environments, such as at night or in a church.
Overall, on-sensor autofocus is a powerful autofocus system that offers many benefits to photographers and videographers. Its speed, accuracy, and quiet operation make it an ideal choice for a wide range of shooting situations.
