Struggling to get the eyes perfectly in focus, Joseph Parry at DIYPhotography.net decided to ditch his entire Canon system for the Sony α7 II. "The ability to setup 3 buttons on the back of the camera to swap between face, eye and main focus instantly is just a godsend. While on a shoot I can compose my image without even thinking about focus, hold one button to grab the eye and boom. Eye focus at f/1.4 and it’s NAILED!"
He goes on to say, "I’m not trying to sell you a Sony or bash a Canon I’m just trying to share as unbiased as I can what I’ve found so far. Ultimately I’m only human so there may well be bias in here, but I hope it to be mild and easily detected to be passed over by you guys."
