闪光灯热靴接口定义

经过千辛万苦的搜索,终于找到了闪光灯热靴的接口定义。

实在想不通闪光灯热靴转换器和延长线为什么卖这么贵。

一、美能达/索尼   Minolta/Sony

1. ISO 闪光灯热靴(旧版本)

  • G = ground (blue)
  • F1 = sync / fire flash (connect G and F1) (red)
  • F2 = flash ready signal / data (white) [also: bidirectional serial data line “F2OUT”, “F2IN”]
  • F3 = TTL OK signal / clock (black) [also: serial data output: “F3L” + “F3H”]
  • F4 = AF assist light control (only on 9000AF, 7000AF and 5000AF)

2. iISO闪光灯热靴(新版)

  • G = ground (blue)
  • F1 = sync / fire flash (connect G and F1) (red)
  • F2 = flash ready signal / data (white) [also: bidirectional serial data line “F2OUT”, “F2IN”]
  • F3 = TTL OK signal / clock (black) [also: serial data output: “F3L” + “F3H”]
  • F5 = flash power, regulated (+5V) & control (only on Dynax/Maxxum 3000i/Alpha 3700i)
  • F7 = power ground (only on Dynax/Maxxum 3000i/Alpha 3700i)
  • F8 = flash power, unregulated (+6V) (only on Dynax/Maxxum 3000i/Alpha 3700i)

3. 连接线端口(同步端口)

  • G = ground (blue)
  • F1 = sync / fire flash (connect G and F1) (red)
  • F2 = flash ready signal / data (white) [also: bidirectional serial data line “F2OUT”, “F2IN”]
  • F3 = TTL OK signal / clock (black) [also: serial data output: “F3L” + “F3H”]

二、尼康 Nikon

TTL Flash Interface connections    (还有几种同步端口,暂时和我没关系)

三、宾得 Pentax  P-TTL

原文地址:http://pttl.mattdm.org/ (这全是P-TTL的内容,但没见到实在的技术实现细节。不过接口定义在外观上还是和Nikon一样的,只是数据传输的信号不一样。)
