想問問各位師兄, 如果閃燈用 ETTL 自動模式既時候, 閃光燈既焦距係咪會跟隨鏡頭既焦距設定而改變?

如果用變焦鏡, 下下都要轉焦距既話, 咁係咪要不停咁調校是閃光燈既焦距?

Thanks!

閃光燈既焦距will automatically adjust base on your lens (of course, under specific zoom range (as far as I remembered 24 - 105).

580EX II 本身既焦距係 24 - 105mm.

如果我支變焦鏡係 17-85mm 既話, 咁支閃燈就唔會自動調校焦距?

The flash will only start 24mm till 85mm, from 17 - 24, possibly you can lower the built-in diffuser to cover the wider range.

上面位師兄,

請問你可唔可以講詳細少少教下少弟?

感激!

You can refer to the following url for more information. Basically, when you set to ETTL mode, the flash output will be automatically adjusted based on your focal length (in between 24mm - 105mm). In case you use the built-in wide panel, it can cover up to 14mm.

師兄,

今晚返屋企試過, 係 ETTL 度行 Auto, 支閃燈顯示屏顯示既焦距係有個 M 字係隔離, 但係用支變焦鏡試來試去, 但係支閃燈既焦距都係要用人手 Set 致得.

唔知點先可以令到支閃燈焦距跟住支鏡既焦距自動調節?

Thanks!

首先支閃吾可以直一定要75度7字型按zoom鈕枝閃個焦距mm閃閃下時轉個盤往左轉回到24mm(有M)再轉多格就會有一個你支鏡的焦距mm(冇M)的之後你支鏡變焦支閃就會跟主變!!
即是支鏡係70mm佢會出個冇M字的70mm!!
我用135mm鏡
105mm以外支閃個mm就會停
支鏡收反到105mm之下就會自動跟反收
24mm以下都一樣
所以cover到佢就cover
所以未見有lens限制

今晚再試多一次, 已經可以了.

唔該晒各位!
