11月30日はオートフォーカスカメラの日です
1977年、コニカ(当時の小西六写真工業)は、画期的な自動焦点技術を搭載したカメラ「コニカC35AF」を発売しました。このオートフォーカス機能は、フィルム写真時代におけるピンぼけ写真の解消を目指して開発、撮影の失敗要因である36%のピンぼけを劇的に改善。この革新がもたらした新しい撮影体験は、その後のカメラ技術の基盤となっているようです。
オートフォーカス
オートフォーカスとは、ピントを被写体に自動的に合わせるカメラ機能のことです。現在では一般的なデジタルカメラでは殆ど標準装備しています。この機能は、機種によっても様々あり、撮影のシーンや被写体によって使い分けが必要です。
コニカC35AF
「コニカC35AF」は、『ジャスピンコニカ』という愛称で、誰が撮ってもピンぼけ無しで撮れるため、それまでカメラを扱わなかった女性や中高年層の市場を新たに開拓しました。そこからこのコニカカメラは、2年間で100万台を売り出し大ヒットしました。
コニカ「小西六写真工業」
「小西六写真工業」の「六」は、1873年に東京の麹町で創業の店が名前である『小西屋六兵衛店』からきているとされています。米穀商からの商い「小西屋」は、東京で有数の大商店でした。6代目の六右衛門は、25歳の時に写真館の撮影した写真に感動して、それがきっかけに写真材料の取り扱いを始めています。その後は、元々の家業から独立し、日本橋に写真材料と薬種の取扱店である「小西本店」を開業しました。
綺麗な写真が簡単に
一昔前は、カメラの絞り機能で微調整をしながら撮っていました。またこれが、人の技量が問われるなどで大変だったのです。しかし今では、スマホなどでもできる「人差し指で当てるだけ」の操作でプロ並みの画像が撮れます。最近はすでに、オートフォーカスという言葉さえも忘れかけるほど当たり前の機能になってしまったようです。
