Some lenses, such as Pentax’ DA* designated models, although normally using an inbuilt motor, can fall back to screwdrive operation when the camera body does not support the necessary contact pins. Thereby, contrast AF makes arbitrary fine-focus adjustments by the user unnecessary. Most multi-sensor AF cameras allow manual selection of the active sensor, and many offer automatic selection of the sensor using algorithms which attempt to discern the location of the subject. Autofocus accuracy within 1/3 of the depth of field (DOF) at the widest aperture of the lens is common in professional AF SLR cameras.

Active AF systems measure distance to the subject independently of the optical system, and subsequently adjust the optical system for correct focus. Phase detection (PD) is achieved by dividing the incoming light into pairs of images and comparing them. Most modern SLR cameras use through-the-lens optical AF sensors, with a separate sensor array providing light metering, although the latter can be programmed to prioritize its metering to the same area as one or more of the AF sensors. Very few cameras provide multi-PD-AF systems with several switchable measurement bases depending on the lens used in order to allow normal auto-focusing with most lenses, and more accurate focusing with fast lenses. Approx. 980 g/2 lb 2.6 oz with battery and SD memory card but without body cap; approx. 880 g/1 lb 15.1 oz (camera body only) 0 to 40°C/32 to 104°F 85% or less (no condensation) PictBridge is a trademark. The phase difference between the two profiles can be used to determine which direction and how much to move the lens to achieve optimal focus.
