久しぶりの投稿です。
そんな間にLUMIXがハイエンドモデルの新製品を２機種も発売しましたね。
ひとつは、G9 Pro（海外ではG9）で、静止画に特化したモデルになります。
そして、もうひとつがGH5Sで、動画機能に特化したモデルになります。
GH5の発売から１年未満でこの２製品を発表することからも、LUMIXの、いやパナソニックのデジカメ事業に対する意気込みを感じます。
端的に表現すると。。。
・動画もいいけど静止画が自慢のG9Pro
・静止画もいいけど動画が自慢のGH5S
・動画と静止画のバランスをとったGH5
といった感じでしょうか。

G9 Proの目玉は静止画における絵作り、即ち画像処理エンジンかなと思います。もやは、単にG8の後継機種とは言えない進化を遂げていますね。もちろん、画像処理エンジンだけでなくさまざまな改善がもりこまれているのはいうまでもありません。そのひとつしてハイレゾ撮影があります、これは80MP（8000万画素）相当で撮影するモードになります。
一方、GH5Sは新開発のセンサで画素数は1000万画素と抑えられています。それにより超高感度（ISO204800）に対応。高感度時のノイズも独自技術により軽減され、暗所での撮影に威力を発揮します。また、民生品として一眼タイプのカメラでC4K/60Pを初めて実現し、プロフェッショナル使用にも耐えうる動画性能も実現。静止画も画像処理エンジンのチューニングにより一昔前の1000万画素とは明らかに違っています。
※C4K/60Pとは、Digital Cinema Initiatives（DCI）が定めたCinema4K（4096×2160）においても、高解像と高フレームレートを両立した4K/60p記録を実現。プロの映画制作にも対応
ここでも、パナソニックのシェア獲得と販売戦略が見えてきますね。動画も静止画も業務用（プロ用途）で使う場合は２台あった方がいいわけです。と、この記事を書いている最中にもGF10が発表されていますね。
私個人的にはGXシリーズの進化も楽しみにしています。LUMIXにはこれからもミラーレス一眼の技術革新を牽引していってもらいたいと切に願っています。
とにかく、お金を貯めないと。。。
