Pixel Opas (for Sony) Review

I had been looking to extend/upgrade my radio triggers for a while now. My current lineup included the Yonguno CTR-301P’s and Pixel Kings for TTL support.

Being a Sony shooter there are limited number of triggers that natively include the Sony/Minolta hot shoe so my choices were limited from the start. I eventually chose to got with the Opas triggers from Pixel, I chose them for a number of reasons;


  1. The use of AA Batteries
  2. Compatibility with Pixel Kings
  3. The On/Off switch
  4. Transmission Range (400m)
  5. Being transceivers they can act and transmitters or receivers
  6. The 2.4Ghz band can be used pretty much everywhere
  7. HSS support


Opas and 43AM


In the Box

Each transceiver comes in its own box, inside you will find a user guide and a nice little bag. Inside the bag, the trigger and a number of cables that enables the trigger to fire studio slaves and older flashguns, also included is a shutter release sync cable.



The build quality is what I have come to expect from the mid range, middle price bracket triggers. The plastics don’t feel as cheap as some, with a fairly rigid feel, the buttons and switches have a good feel to them too.


The bottom hot shoe fitting also feels solid with a wheel turn lock to keep the trigger firmly in place. The hot shoe fitting where you would attach your flash feels pretty solid too.

My only complaint is the aerial, its fairly rigid. This in itself could be a good thing, but if you catch it against anything or pull the trigger out of its bag with a little too much force, it may snap off. I must add, this has not happened to me, it is just an observation.



For the relatively low price (I paid £108 for a set of three), these triggers are pretty packed with features.

Running on AA batteries is a massive bonus, unlike some of the cheaper triggers available that run on expensive, hard to find batteries such as my CTR-301P’s. AA’s are radially available and I for one carry a number of spare sets for my flashguns.

There are four channels each with three groups, they seem to have channel and group memory too allowing for pre shoot setup. If you setup CH1 to fire on Group A, CH2 on group B and CH3 on group C, turn them off, change from a receiver to a transmitter or visa versa they keep your settings.

On top of the transceiver, as well as the aerial is a 3.5mm jack for cable sync connection and a mini USB port for firmware update or charging/power.

On the left, the channel select switch and the PC Sync port. On the right, the on/off switch and the receiver/transmitter select switch.

The front plate has the flashgun hotshoe, channel selection and a test or shutter release button.

The back plate has the battery door and a ¼” screw for tripod/light stand fitting.


Single Opas

As with most of the triggers on the market, the Opas’s are easy to setup and use, simply attach one to your camera and one to each flash you wish to use and bam your set.

The channel’s and groups make it easy to switch between setups.

Flash sync works from 1/200 all the way up to 1/8000 with HSS.

When using the transceivers with the Pixel King transmitter works ok, I did have a few misfires and the transmission range is reduced.

I have tested the published range or 400 meters, roughly pacing out 350 meters they worked without fail in open space and in a woodland area. I only managed to try the remote shutter release function to a range or 150 meters but this worked just fine too.

I have used the triggers for five shoots now and the range test, probably firing around 2000 shots and the batteries are still going strong.

The triggers are advertised to work with the entire Sony DSLR/SLT range. I have tested them on my A200’s, A77’s and a friends A580, A700 and an A900. However, when I attached them to my A200, they would not fire. The shutter release function worked though. They worked without issue with all the other bodies.


Overall I have been really impressed with the triggers. The compatibility with Pixel King triggers, use of AA batteries and doubling up as a shutter release are for me, really big plus points.

As I stated above, the aerial is big and may be snapped easily but carful usage would minimize this risk.

I would recommend these triggers to anyone looking for a budget setup or someone wanting a good customizable manual setup.
