Autofocus

When combined with continuous focus, Eye-AF is a great feature for capturing portraits - especially of kids that won't stay still.


The a7 II uses the same AF hardware as its predecessor the first-generation a7, but Sony claims that autofocus performance has been improved by around 30%. In our testing we have no reason to dispute this figure, and in everyday use the a7 II's AF is more than capable of keeping up in most situations.

The a7 II's autofocus might be perfectly acceptable, but the a7R II is in another league. Both cameras use a 'hybrid' system which combines on-sensor phase-detection pixels with conventional contrast-detection but with more than three times as many phase-detection AF points as the a7 II, and the ability to focus third-party lenses (later added to a more limited extent to the a7 II via firmware) the a7R II's AF specification impressed us greatly when it was first announced. To this day it offers the most expansive AF frame coverage of any full-frame camera.

While it can't keep up with the action as well as the market-leading 3D AF Tracking system found in Nikon's current DSLRs, the a7R II's ability to find and track an eye in continuous Eye-AF mode for example is incredibly useful for wide-aperture portraits of even moving subjects (a7 II will find, but not track, an eye), and low-light AF reliability with fast lenses is almost a match for the best DSLRs.

That's the good news - the bad news is that there's still no way to position AF point by touch on either camera, and the a7RII and a7 II's control and menu ergonomics make it annoyingly tricky to find, set and master their extensive autofocus settings.
