Sony a7III PDAF Artifacting, Auto Focus Performance, Canon Lenses, Reviews, And More


DPReview published some photos from the Sony launch event of the Sony a7III and some readers have sent us the photos over the past few days, which we previously covered, but there seems to be some confusion that there is a problem. All cameras with PDAF will show these kinds of artifacts under the right circumstances, which is why some companies stick to CDAF. Contrast detect autofocus cameras don’t have this kind of artifacting, which are caused by phase detect pixels under very specific circumstances.

This kind of issue can’t be fixed with a Firmware update unless you’re going to blur the detail to remove these artifacts, which is something better left to photoshop. 99.9% of the time you will not see these and many other PDAF on-chip systems have demonstrated this issue over the years without photographers being affected. There is nothing unique here, but feel free to pixel peep. If you want to check out the full resolution photos Girls Face 1Girls Face 2, Light 3.
