Firmware V1.01 for the Sony a7 IV included the promise that it ‘improves the accuracy of the Eye AF characteristic.’ Since this was one of many criticisms that held again the rating of our assessment, we re-tested the digicam to see whether or not the tendency to fractionally front-focus in eye AF mode has been resolved.
We confirmed with Sony that the replace was meant to deal with Eye AF nonetheless it was activated; whether or not by assigning a button to the operate or by its automated use when ‘Face/Eye Precedence in AF’ is turned on.’
Having examined the digicam with a number of topics and quite a lot of lenses, we discovered the attention AF operate can nonetheless are likely to concentrate on eyelashes, slightly than the topic’s pupil. It’s one thing you’ll solely are likely to see when taking pictures at pretty vast apertures however we nonetheless discovered we might get higher outcomes with handbook focus.
We’ve included these findings in our review however can not discover sufficient of an enchancment to revise our scoring.
In abstract: We want yet another firmware replace Sony!
