...請問如果相機本身無對焦輔助燈~

...有無一o的外接閃光燈會設有對焦輔助燈o架 ??
...或者好似的防紅眼功能咁, 會發出一o的光線射向主體以便對焦 ??

...( 因為見到有的人影相時, 部機會發出一o的圓圈射向主體,
唔知係相機定閃光燈發出, 請問係對焦輔助燈定防紅眼o架 ?? )

...THZZZZZZZZZZZZZZZZZZZZZZZZZZZ

對焦輔助燈 from external flash - no such thing

red eye reduction from external flash - no such function

Remember external flash only flashes once. There is no pre-flash like some on-camera flash.

If you mount the external camera directly on top of the camera, there may still be a chance of some red-eye.

If you put the external flash (slave) next to the camera (couple of inches to the right or left of the camera), there will not be any red eye as the eye will not reflect the flash light directly back into the lenses of the camera.

I just take Nikon SB-50DX & 80DX for example.

When they are used on dslr, there will be 對焦輔助燈 from the external flash.

When they are used on coolpix 5000 , the internal flash on the body will act as red eye reduction while the external flash is fired. (CP5700 cannot)

But dc (unlike dslr and slr) usually cannot use all the functions of an external flash.

好多閃光閃都有對焦輔助燈架...
不過主要係用o係slr度，dc度用唔用到我就唔清楚

至於防紅眼，使用外閃本身已經可以大大減低紅眼出現o既機會

[oldpear]

呢點係我一向評擊5700設計既問題, 亦好可能係留有後著, 唔係新型號邊個買?

SLR的防紅眼外閃作用真係好大, 以F90/F100為例, 呢兩個半專業級型號都冇內閃, 但配上外閃之後, 輔助對焦燈可使AF時間縮短至零點幾秒, 防紅眼閃燈係閃燈頭先閃三野然後正式引發, 呢三野強光近D睇都標眼水, 莫講話防紅眼咁簡單啦.........反觀5700的防紅眼, 只靠手柄果支象徵式INDICATOR, 我哄埋去望都唔"殘"眼, 真係得啖笑, 隻手大D仲遮埋佢添!

各位大佬~

...咁o即係可以放棄買外接閃光燈既念頭啦 ~~!!

...如果各位大佬仲記得既話, 小弟o岩o岩買o左部 CP 5700 "ga...ma..." ~~

...我諗住買外接閃光燈, 原因唔係因為覺得內建o個閃光燈唔夠光~~!!
...係因為諗起o的外接閃光燈好似會設有對焦輔助燈~~
...諗住可以幫助我解決難對焦o既問題~~~~~~~~~

但而家..............................................
...唉``````````````````````!!


...另外想問o下~
...如果用o係 CP 5700~

...有無外接閃光燈對應到頻閃o既 function 呀 ??

...THZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ

In fact such problem also occur on fuji s602z, and i am also has the same thinking as yours - try to buy a external flash lamp with af assist lamp........however, s602z's hot shoe only support one connector(you can modify the case in cp5700), that means the assist lamp yet can not be use ......then how i can improve such situation???

one of the solution is to modify the electronic structure of the external lamp...^^

i have try that and also found out which connector on the hot shoe of the external lamp control the emitting of the af assist lamp (it is a for canon model).... but the lamp only can be light up for short distance, if you need information can start other thread to ask me.

the second choose is make your own af assist lamp....i am making this and soon be announce ^^, if finished, i will announce at "s602z 討論區".

...我都有諗過自己整番個 AF assi light~

...不過真係無勇氣攞出去用~~~~~~~~!!

...唉```````````````````````````````````

[ousi]

咁可唔可以用電筒用手照住就算(在黑的地方用)?
我成日都有電筒係身.

[BlackColor]

...但係 AF or AE 準確嗎 ??

...我指如果用電筒照住, 對焦後熜電筒~~

...咁曝光咪唔同o左, 會唔準囉 ~!?

common sense 控 shuttter switch只 lock AF, 唔會 lock AE.
lock AE 用第二個制.

[brett]

5700有得set
AF / AE一齊lock
只lock AF
只lock AE

[hkhei]

>>common sense 控 shuttter switch只 lock AF, 唔會 lock AE.

剛好相反，大部分機o係半按快門o既時候會lock af同埋ae
當然，有o的相機會有得set，但係預設都係係兩樣lock晒

black color o個個情況要先用ael lock左個ae
再開電筒半按快門對焦

The main function for the external light is not only for red eye removal or focusing but also provided better photos.

Because of these samples, I just bought a second hand Nikon Flash and having more fun with it with the 5700.

Hope this will help.
