Bronica Professional Lens Hood G [Camera Accessories]
ブロニカプロフェッショナルレンズフードG。
普通みかけるのは円筒状や花形のフードだが、これは蛇腹のフード。長さを変えることで複数の焦点距離のレンズに使用できる。もともとはブロニカの6x7版のゼンザブロニカ GS-1用だと思われるが、35mm版のカメラでも使える。アタッチメントは72mm、82mm、95mmなので、写真の例では77mm→82mmのステップダウンリングを使っている。蛇腹を一番縮めた状態では焦点距離28mmのレンズに、一番伸ばした状態で焦点距離50mmのレンズに使える。
展望台でガラス越しに写真を撮るとき、ガラスの反射を抑えるフードとして中古品を購入したのだが、蛇腹の角度が変えられるようにガイドレールを外すのが面倒になって、そのままになっている。
このフードを付けて写真を撮ったのは1回しかない。
Bronica professional lens hood G.
Usually have been seeing the hood is often cylindrical or flower shape, this is the bellows of food. It can be used for more than the focal length lens by changing the length. It is originally for Bronica GS-1 of 6x7 size, but it can also be used in a 35 mm size of the camera. The size of the attachment is 72 mm, 82 mm, so 95 mm, in the example of the photo are using a step-down ring of 77 mm to 82 mm. A bellows can be used for the lens of the focal length 50mm in the state extended to the lens of the focal length 28mm most in the state shortened most.
When taking a picture through glass at an observatory, a used article was bought as the hood which suppresses reflection of glass, it becomes troublesome that guide-rail is removed so that the angle of the bellows may be changed, it is remains.
I took pictures only once with this hood.

Nikon MC-23A [Release]
ニコンの一眼レフにはアクセサリーのコネクターの形状が2種類あるので要注意だ。丸い10ピンターミナルと四角いアクセサリーターミナルだ。GP-1には両方のケーブルが付属しているので問題なく使用できるが、多くがコネクターの形状が1種類なので買うときはカメラ屋の店員に確認する方が良い。MC-23Aは10ピンターミナルのカメラ同士を繋いで、一方のカメラのシャッターを切った時に他方のシャッターも同時に切るのに使う。長さが足りない時はMC-21Aを使う。鉄道写真では、広角系のレンズを付けた1台を三脚にセットしもう一台には望遠系レンズを付け手持ちで構え、2台で同時に撮ったりすることもあるようだ。以前、400WSのストロボで2台でシンクロできるか試したことがある。2台のカメラのシャッタースピードを1/80秒にし、三脚側のカメラをマニュアルフォーカスにしたら問題なく両方の写真にストロボ光がシンクロしていた。クリップオンタイプのストロボだと発光時間が短い所為か三脚側のカメラの画像の一部が暗く、もっとシャッタースピードを遅くする必要がある結果となった。
後日、10ピンターミナルを持つD500を買ったので、1台のストロボをD800とD500で試したところ、シンクロしなかった。
A single-lens reflex camera of Nikon has 2 kinds of shape of the connector of an accessary, so when buying it, it's requiring care. There are two types of round 10-pin terminal and square accessory terminal. Both cables attach to GP-1, so it can be used with no problem, but the shape by which much is a connector is one kind, so when buying it, it's good for camera store's shop assistant to check it. MC-23A by connecting the camera with each other 10-pin terminals, when releasing one camera, also to release the other at the same time. When the length is not enough use the MC-21A. In the railway photographs, set the camera with wide-angle lens on a tripod, with a hand-held the other one camera which attached telephoto lens, and taking at the same time in the two cameras. Previously, I tried whether two cameras can be synchronous with the flash of 400 WS. The shutter speed of the two cameras are in 1/80 seconds, and the camera on tripod set manual focus, strobe light was synchro in both camera without problems. Because clip-on type flash short light emission time, a part of the tripod-side camera image is dark, it resulted that the need to slow down more shutter speed.
I bought a D500 with a 10 pin terminal at a later date, so when I tried one strobe with D 800 and D 500, it did not sync.
