9/6/2023 0 Comments Nikon d750 full frame in focusThe fine resolution of the D750's metering sensor, combined with tuned AF algorithms, enables recognition of detailed patterns to help track subjects accurately - by automatically selecting the appropriate AF point to stay locked on the initial subject. All AF-continuous modes engage tracking along the depth axis 3D focus tracking mode also tracks a subject around the frame, taking it up to three dimensions. Perhaps one of the most compelling uses for the RGB metering sensor is in 3D focus tracking. In most situations the D750's face detection system (which can be used when shooting with the optical viewfinder) works as advertised.Ĭameras without this feature tend to focus on the closest object which isn't always desirable. Even if there's an object closer to the camera, the D750 will stay locked on a face. The camera automatically focuses on faces when 'AF area' is set to 'Auto', in both AF-S and AF-C modes. The image above is downsized so click to see the full-size version.īelow is an example of D750's automatic face detection when shooting through the optical viewfinder. We took a full-size image and scaled it down to 213 x 142 pixels, then blew it back up for ease of visualization, then overlaid the D750's AF grid. Given the high resolution of the metering sensor it's able to pick out not just faces, but also fine details like eyes, which extends to tracking movement across the frame.Īs we showed on the previous page, this is a representation of how we believe the 91k pixel metering system 'views' a scene. As a refresher, take a look at what we believe the D750's metering sensor 'sees' when evaluating a scene. Autofocus (Subject recognition & tracking)Īs we alluded to on the features page, the D750's AF system works with the D750's metering sensor to provide advanced subject recognition and tracking, including face detection, during through-the-viewfinder shooting.
