我搵到一個差唔多三十年既閃光燈~~入4粒AA電
牌子係national
咁我用50D既
咁我插左入去又用得到~
但係會唔會傷機呢~~
我上網睇過~話依家D相機用低電壓
舊果D閃光燈同高電壓~~
咁會唔會有影響架

唔該各位CHING幫幫我啊~~

should be no problem.... as your camera only give the flash a trigger like a simple switch.
how many contacts in the hot shoe of your flash ??

[pakyintsui]

一點

[h0001244]

perfectly ok.... but you have to control your aperture to get the correct exposure as your flash would only gives full output or if your flash has exposure control, that would just be perfect for your controlling

我果枝係依隻

you must check the flash trigger voltage before use, usually below 10 V is ok for DSLR

PE-20S No 6.16V, per Akira So

但我果枝係PE-201C=V="
應該都係一樣

EOS Safe?係NO 者係點解

[h0001244]

Since 傻柏 mentioned it uses 4粒AA電, as the trigger circuit is of primary circuit which is now 6V, it could be used in canon 50D

[pakyintsui]

者係用到@_@"好野~不過唔知有冇岩枝燈果D罩~~

[h0001244]

make the 罩 yourself la

[Obi-Wan]

h0001244
the trigger voltage of flash is not governed by the no. of AA cells, it is governed by the circuit design.

PE-20S is not EOS safe > 6 V

[h0001244]

Obi-Wan, you are right.

then 傻柏 has to put the probes at the trigger contacts and short both contacts by the camera to find out the voltage difference that generates when high current passes through the flash inside.

[Obi-Wan]

If 傻柏's camera has PC cord connector (CANON 20D, 5D, 1 series or above), still can connect to the flash to that PC cord connector (can standard 250V)
