快門慢過最快閃燈同步快門, 就幾慢都同步架啦。

其實Canon係咪冇慢快門同步架！

[h0001244]

It is a basic function that all brand SLR have as all SLR can control the shutter speed during flash. No need to specify this 慢快門閃燈同步 function in the spec.
But for DC camera, not all camera can lower the shutter speed during flash. Therefore 慢快門閃燈同步 is specified.

個快門任你較,你中意幾慢都得^_^

後簾同步???閂快門先閃,好多機都有,7D....有

其實唔係canon冇，而係呢個level的機冇明顯擺出來！ 以前用400D 係有個夜景模式，即係閃燈慢快門同步。30D 40D都好似有呢樣野。頭先摷番份書明書出來看，AV mode 如果在Fn度set 0(即係auto, 快門會訂在1/250至30秒)

其實對於我呢個懶人來說，呢個功能好好用，自己用M mode調校唔係唔得，不過閃燈輸出要校番細，否則主體會爆光！ 又要試幾張來找出個正確暴光，所以如果相機有呢個功能幫手就唔駛煩！(都係自己懶啦！)

.....越黎越多呢種問題 =_=
甚至有人問CANON 有無呢個 分唇 =_=.......

basically all canon camera are defuat is slow sync flash

not like nikon need to set

[hanny]

because canon not like nikon
when taking flash photo nikon is lock to 1/60
so if need slow sync have to set to slow sync funtion to let the shutter speed under 1/60

but canon no need becasue canon not lock at 1/60
so canon will take the piture by the real enviroment shutter speed
but if really want to lock the shutter speed at 1/60 the new model from 60d
there are a funtion can lock at 1/60 for normal flash sync
if you turn it off canon will automatic slow sync

你用手動燈?
TTL燈唔洗較架喎

[hanny]

cannon doing slow sync with e-ttl2 flash is very effiently
and very stable

not like nikon
if nikon do slow sync with flash for portrait at night by matrix metering
it is very easy to over 0.7ev to 1ev

but canon donot have this problem
