I've posted a thread a few days ago asking about these thing, but it seems that not many people are using these.
So... I just went ahead and bought it.
Just a disclaimer: I'm not a native English speaker, and I'm just staring to get into flash photography,
so please excuse the typos and this shallow review.
So I was looking for a remote trigger on the internet, and intimidated by the prices of PocketWizards, I found two cheap brands.
The Youngnuo RF602 and Aputure Trigmaster II (Cactus aren't available in my region)
Both from China.
The youngnuo has a drawback in that it doesn't have a power switch on the transmitter, so it might fire off when accidentally pressing the test button.
So let's go right in and see what the Aputure offers
#1
I bought these through air mail, so the batteries were taken out
#2
enclosed are 4 connectors, from left to right:
2.5mm to 3.5mm, 3.5mm to phone(sorry, i don't know the proper name for this), PC sync line, 2.5mm to 2.5mm
the former two are for connecting to studio strobes, PC sync for older cameras without hot shoe, and the last one is the shutter line for remote shutter release.
#3
remote flash triggering
#4
remote shutter release
#5
testing the remote flash triggering from 10 meters away.
Now, the company sells different models for different brands(except for Pentax)
They are different in the shutter release line AND the voltage it generates to wake up flashes.
Because the Pentax uses the same shutter release line as some Canon, you could just buy the one for Canon.
However, the "wake flash up" function would not work.
This thing works well with my K-5 and Exakta AF38DPZ (same thing as a Vivitar 383)
no misfires so far.
