The camera always follows the subject even if he or she turns to the side. Because it has become so reliable on the most recent E-mount products, the photographer can concentrate on expression, position and movement of the subject without worrying about positioning the single focus point.

Thanks to the advancement of the company’s phase detection autofocus, as well as the more elaborated software algorithm for subject tracking, Sony’s Eye AF has set a benchmark in the camera market.Įthics statement : the following is based on our direct experience with the Sony A6400, A7 III and A7R III that we bought for review and comparison purposes. Sony is the brand that has made the most progress in this segment. Some products can pick out both faces and eyes at the same time, but if the camera concentrates its resources on only one thing, it can be more efficient. With face detection, it is not uncommon to end up with the ears or the nose in focus instead, especially if you play with shallow depth of field and close focus distances.

Of course there can be exceptions if the photographer is trying to communicate a specific message, but the general rule is that a good portrait must have the eyes in focus. If the eyes are out of focus, even just slightly, part of the identity of the person being photographed can’t be read and as a consequence, the emotional connection the eyes transmit is lost. Well, the explanation is quite simple: when you take a picture of a person, achieving correct focus on the eyes is essential. Among the various improvements brought to autofocus technology over the years, I consider eye detection one of the most interesting.
