競合製品との比較
Sony a1 IIが新たにトップ5入りし、このクラスの競争がさらに激しくなりました。a1 IIは前モデルからAFと連写性能が大幅に向上しており、特に動体撮影では本機を上回るケースもあります。一方で、本機は高感度耐性とダイナミックレンジで依然として優位に立っており、風景やポートレートを中心に撮るなら本機の画質は今でもトップクラスです。a1 IIの登場で「万能機」としての立ち位置は揺らいだものの、純粋な画質重視派には引き続き強くおすすめできます。

総評
Sony a1 IIの登場で万能性では一歩譲る場面が出てきましたが、画質そのものにこだわるなら本機は今でも最高の選択肢の一つです。高感度のノイズ処理と色再現はa1 IIより自然で、じっくり構えて撮るスタイルにはこちらの方が合っています。動体メインならa1 II、画質メインなら本機、という住み分けがはっきりしてきた印象です。
