各位師兄好
小弟想買支閃(580EX II)
買果時支燈有咩要試的地方?
謝謝各位^^

試下個接觸位.....
我買果陣試過一支耍插幾次先可以用到TTL....
都唔知係我部機問題定係支燈問題

Obi-Wan's Guidelines for checking Flash
1. check metal contacts outside on the flash for the shoe mount AND inside the battery chamber, new one should not have any scratch
2. check plastic mount on the flash shoe, new one should not have any scratch

mount a zoom lens, e.g. 18-200
3. change the focal length, half press shutter button, the focal length data on the flash should change
4. cover the lens with the lens cap, half press shutter button, the RED lamp for AF assist should be on (unless u disable it in some EOS cameras)
5. use M mode, no need AF, set 1/200 or any syn speed, change F no. from 4 to 22 on a closed object with ISO 100, the exposure should be nearly the same
6.. repeat step 5 with bounce mode, ISO 400
7. set high speed sync, use M mode 1/1000, ISO 1600, repeat step 5

小弟都要買閃光燈
但英文都好水皮睇唔明特別係3同4
我估大约的內容係
1)睇下D金屬接頭有無人用過或花
2)睇下閃燈位有無花
3)對焦半按快門睇下閃光量改變的數據變化
4)保護鏡蓋,半按快門睇下自動對焦時紅色燈應該亮 如果不能即對應唔到
5)用M mode 唔雖要自動對焦,設定快門1/200 ISO 100 然後改變光圈由4至22出來的相個曝光應該一樣
6)重復5的方法設ISO 400
7)重復5的方法設1/1000 ISO 1600

kwmsn師兄..唔該哂你^^
第4)保護鏡蓋,半按快門睇下自動對焦時紅色燈應該亮 如果不能即對應唔到
是指那一個蓋?紅燈是在閃燈上的嗎?

第4點係求其搵野遮住個鏡頭（鏡頭蓋最方便），係想試下支燈個鋪助對焦紅燈著唔著咁解。

最基本係要安裝咗支燈後用到ETTL，因為有時接觸不良會用唔到。 用M mode iso400, F4開始試拍幾張睇下曝光正唔正常（室內計）。 如接觸不良佢會全輸出，張相應該會爆晒。

我有次經過三城店鋪,,原黎個售貨員都唔識試閃燈,要請教人喎,呢間鋪係西菜街!!!!

唔該哂各位師兄
