Sony Alpha A1

General Commentary on Sony A1 Eye AF

This page starts my evaluation of the Sony A1 for its Eye AF feature, for humans, animals, birds.

The first thing to notice with the Sony A1 is its hyper responsiveness. No other camera I have ever used comes close to how snappy it feels, both when focusing and pressing the shutter release. The zero-blackout is super nice as well.

With Eye AF tracking enabled and with AF-C, it can be seen in real time that the A1 not only tracks eyes straight-on, but at all angles, up or down, occluded or fully open. It even reliably tracked Tigger’s eyelid with the eyes closed for several seconds. Pretty impressive!

I had to work hard to forget about the AF sensor indicators; I am so used to focus-and-recompose and paying attention to where I put them. My first shoot taught me that I will have to retrain myself for this type of shooting to focus on the composition and only the composition—which is a GOOD thing.
