おまけ！A2のF2.8の内部構造 ― 2008/10/15 20:24
おまけにA2f2.8モデルの内部構造です。kanさんのおっしゃる通りにシャッターは逆付けされています。アイレスのカメラで多くあった構造です。逆にすることで絞りが前にくるので開口効率があげるために逆付けしたと思われます。
ファインダー部は、ビームスプリッターが使用されており非常に豪勢なのですが固定方法等がコストダウンのため。やや貧弱になっています。縦型シャッターダイヤルも非常に面白い構造です。なぜ縦型かと言いますとシュー部分に露出計を付け連動させる為に縦型になっているわけです。横型にすると連動部の構造は複雑になってしまいますので。
カメラ内部の彫り文字は、今回は何の意味があるのかな？とか思ってしまいます。内部を見ると判子や掘り文字やサインがあって面白いですよ

望遠レンズのみですのでこのような構造になっています。でも良く考えましたよね！前回りの構造はA,A2,オートワイドまで同様な構造になっています。Aシリーズまでの考え方は特徴があって面白いですね。アメリカ市場を目指したのであのダルマ型になったと言う話を聞いたことがあります。

Woah! I'm really enjoying the template/theme of this blog.
It's simple, yet effective. A lot of times it's
very difficult to get that "perfect balance" between superb usability and visual appearance.
I must say you've done a great job with this. Additionally, the blog loads super quick
for me on Safari. Exceptional Blog!

望遠しかないんですか、それで構造が納得できました。
前周りの構造は無理がありますね。その割に故障しにくいから良いカメラ
ということなのかな。意外に使いやすいのはミノルタらしいです。
