為什麼有banding DP Review有解釋. 重點是第一句. ""we've found common to all cameras with masked phase detect AF pixels when shot a certain way: " FujiFilm XT2和A9搭配大光圈鏡頭直接照射強光引誘發耀斑都有同樣的問題. 解釋: 這個問題是普遍的.
"we've found common to all cameras with masked phase detect AF pixels when shot a certain way: with very fast lenses wide open pointed directly at bright light sources to purposefully induce flare (e.g. here and here). In continued shooting today in the same venue and lighting, we noticed no issues shooting more modest apertures and zoom lenses."
