Default Flash trigger for NEXes

NEX3 ... NEX7

Description of the SYK-5 flash trigger. You can use it in "normal mode" or with adjustable ignoring of pre-flashes.

The little SONY kit flash is either used "direct" or without visible flash -
an infrared clamp catches all visible light and lets through only IR.
This IR light is enough .. even over 5, 6, 7 meters to fire the trigger.

G'day DD

This is excellent news & info ... 10/10 for you
For me, to see the small rotary-knob addition to the flash trigger makes it all worthwhile > I have not seen these models before but I will now go chasing them

Well done
Regards, Phil

I use for red-eyes-lightning around the center position 12 o'clock, no, rather 11 o'clock of the potentiometer ... two or
three attempts and it's okay.

Begin with right side of potentiometer, then turn the potentiometer
slightly to the left until you get the right moment for main flash (I think this is flash 5).

Ditto for cameras with flashes for measurement.
The process in the small cube is simple: the potentiometer sets a delay after which the sensor reacts to a flash.

The strength of the Sony-flash is not critical - because the sensor reacts even to infrared lightning - 15 feet away.
From METZ you can order IR clamp for ca. € 7.50 (spare part)
With my lightning flashes, I can adjust intensity in 1-7 steps

Transmitter fitting to SONY Alpha / NEX7



Receivers you get for $ 8.50 or $ 8.00 (incl.ship.)
PT-04 works with 433 Mhz, while Yongnuos are working with 2.4 Ghz.

Both are available as sets with transmitter and 1/2/3/4 receivers.

DonalDuc - I believe this only works for the NEX-7 which has a full sony alpha hot shoe - for the nex-3, nex-5 models this won't fit.
