ソニーは、ミラーレス一眼の新スタンダードモデル「α7IV」を発表しました！ 爆売れしているa7IIIの後継機ということで期待されていたわけですが、主なスペックは、3300万画素、ISO拡張50-204800、4K60p動画(Super 35mm)、7Kノンクロップ4K30p、AF/AE追従10枚/秒連写、5.5段手振れ補正＋アクティブ手振れ補正。UHS-II SDXCデュアルスロットで片方はCFexpress Type A兼用、バリアングル液晶(タッチスクリーン)、368万画素EVFなどなど。 待望の4K60P動画が撮影できるようになりましたが、残念ながらAPS-Cサイズにクロップされてしまう仕様。
さっそく、B&Hにはレビュー動画が投稿されました。
