Ojecoco H-430 triggers announced, reviewed

Update: for the final production models, see our ComTrig G430 review.

Chinese trigger manufacturer Ojecoco have partnered with British photographic supplier CotswoldPhoto to develop a new kind of wireless flash trigger. The Ojecoco H-430 is a stripped down accompaniment to the firm’s high speed H-550 series triggers (reviewed here).

Unlike the transceiver-based H-550, the Ojecoco H-430 has distinct transmitters and receivers, apparently making the triggers “faster with lower latency”.

Ojecoco H-430TX and H-430RX for Nikon

The H-430, which comes in Canon and Nikon flavours, bears resemblance to other wireless remotes such as the Phottix Strato Multi II and Pixel Rook. Indeed, it shares many of their features, including wireless flash grouping, AAA batteries and TTL pass-through on the transmitter.

However, Ojecoco have an ace up their sleeve. Crucially, the H-430 is inter-compatible with the H-550, allowing shutter speeds up to 1/8000 second to be obtained when the H-430 is triggered by an H-550 in high speed mode. As you can see from the chart below, this gives an Ojecoco user many more shutter speeds to choose from:

For more details on how high speed mode works, see our separate H-550 review.

What’s more, there is an ECP port on the H-430TX for “trap shooting” using sensors attached to the transmitter. This will enable users to trip their cameras and/or flashes in response to sound, light, pressure etc. for applications in wildlife and scientific photography.

Specifications

  • 2.4GHz signal with 5 channels
  • 3 groups with 7 combinations
  • Up to 150 metre operating range
  • 2.5mm synchronisation ports
  • 300V maximum synchronisation voltage (on receiver)
  • Transmitter and receiver both take AAA batteries

Hands-on review

CotswoldPhoto sent us a pair of pre-production Ojecoco H-430s to evaluate in advance of their release. (See here for a review of the final models.) Ours were for Nikon, but results for Canon should be similar. We weren’t able to test every single feature since some parts of the design were only completed between this batch and the final production run.

Straight out of the box, the H-430s have an intuitive, easy-to-use design that for the most part negates the need for the clearly-written instruction manual (not included, but available as an electronic PDF). Buttons are sensibly labelled and everything is easily accessible. You can change groups, channels, modes and batteries, even with a flashgun mounted on top and a light stand underneath.

The devices feel solidly made. A metal foot on the transmitter, locking rings and locking pins all serve to inspire confidence that your H-430s will sit securely wherever you put them.

The transmitter (H-430TX) and receiver (H-430RX) look almost identical. On the right side of the device you’ll find an Off/Mode switch and a Group button. On the transmitter there is one mode for handholding (for use of the two-stage test/shutter button) and another for syncing with your camera. On the receiver you can set the unit to trip either a remote camera or an off-camera flash (suggesting you can’t do both at the same time).

On the left hand side is the Channel button and two 2.5mm synchronisation ports. On the receiver these are outputs to a remote camera or flash. On the transmitter they are inputs – either from your camera’s Prontor/Compur sync port, or from an external sensor (ECP) for trap shooting.

Despite the claim of “lower latency” in this model, we achieved the same maximum shutter speeds as obtained in our H-550 transceiver test. On the Nikon D40 we got 1/1250 second and on the D700 1/250 second. A manual flash mounted on the transmitter’s TTL hotshoe can synchronise up to 1/2500 second with the D40.

One quirk we noticed is that wireless grouping works only with flashes, and are disabled when triggering a remote camera. I’m not sure why this is, but it could cause frustration for someone wanting to trip several remote cameras in groups. Channels are unaffected.

There were no problems using these triggers at extremely short to long ranges, and no misfires or missed shots were encountered.

Overall, the Ojecoco H-430 is an excellent all-round trigger. It has everything offered by the latest remotes from other manufacturers with the possible exception of an external power input (found on the dearer Bishop, Opas and Strato II). The unique selling points are price (see below), compatibility with the high speed H-550 series and the ECP port for trap shooting.

Where to buy

CotswoldPhoto is Ojecoco’s exclusive worldwide distributor for H-430 flash triggers. They are set to be officially released tomorrow, on Saturday 3rd December 2011. An Ojecoco H-430 transmitter/receiver kit will be priced at US$80/£50/€60. Additional receivers will cost US$35. Note that prices may vary with exchange rates.

You can also win a set in the first round of our upcoming photographic competition.

    I still want to ask about those H550 triggers:

    So could you measure the light loss you get when shortening shutter times?

    Could someone clarify if Pixel Knights can be used with non TTL system flashes (3rd party flashes)? Also, what is power loss with those?

  • richard

    I’ve had various poverty wizards, yongnuo 602′s and pixel kings (preproduction units worked with canon 550ex but production units don’t work with 550 ex flashes) and I refuse to buy Phottix Odins because preproduction units had AF assist light but production units don’t have a AF assist light on the TX!!!!!!

    There’s a whole load of radio triggers that don’t quite do everything that someone could want.

    Now that I have used TTL triggers would never go back to using triggers that don’t allow me to change power levels from the camera somehow especially if they are designed to trigger speed lights.

    Somebody should Chinafy the radio popper JRx system and make it better e.g. AF assist on TX, hyper sync and bigger and more control dials and an Rx with built in hot shoes for respective flashes.

    Just saying my 2 cents worth…..

    my order has arrived from CotswoldPhoto, great quality triggers very well made. Looking forward to trying these out..

  • Eric

    Would like to clarify something..

    So the RX of the H-430 is backward compatible with the H-550.
    Does this mean one will only need 1 H550 Transciver which triggers the H-430 Rx unit?

    And by doing so, how does one then utilise the ECP port in the H-430 (which I believe is not available in the H550)??

    Would it be a matter of sitting the H430 Tx on the H550 which together sits on the camera?

    • David A. Selby

      The H-550 is being redesigned. Its successor may have an ECP port.

  • CotswoldPhoto

    Hi

    I received the first Mk2 H-550 today :-) Nikon version only for now. It does not have an ECP port. I have seen very little from Ojecoco about the ECP port yet. This is all they have sent me (converted from Chinglish):

    “ECP Auto-Triggering Port

    The H-430TX has an ECP port to accept signals from various sensors, such as vibration, light, infrared, sound etc. The H-430TX is attached to the sensor in a remote location, with either a H430RX (in Camera mode) or an H-550TRX attached to the camera, so that the camera can be automatically triggered, and if needed relay to flash.”

    As yet I am waiting for further details.

    I will post pics of the new H-550TRX on flickr as soon as I have done them (maybe tomorrow night). What’s new? The HSS wheel now has numbers for scale. The range of HSS adjustment seems bigger. The case seems better fixed at the rear. The locking wheel is now bigger and easier to use (the same as the one on the H-430). The output transistor is 300V safe in receiver mode.

    And Eric, yes, you can use the just one H-550TRX on the camera to trigger remote H-430RXs.

    A bit of an update, bearing in mind it is Chinese New Year so only a few staff are contactable at Ojecoco … the first H-550s were ‘test’ versions (NOW they tell me). They have a problem with the Channel settings. This is also fixed with the Mk2. This means these earlier H550s won’t work with H430s. We are swapping out Mk1s we sold with Mk2s as stock comes in.

    Also, Ojecoco tell me that they are working on a remote unit (that either takes sensor input or has sensors fitted) and converts the sensor signals into a signal for the H-430 ECP port, that unit plus into the H-430 ECP port.

    is possible to shoot study flashes at 1/8000?

    or just TTL flashes?
    thx

    • David A. Selby

      You can shoot some studio flashes at 1/8000s, depending on the flash and camera.

      • Kycas

        thanks for your answer…is helpful!!!
        I have the D300 and D5100 studio flash Corona 250T
        How I can know if it’s possible?

        • David A. Selby

          The D300 is tested to work with the H-550 series flash trigger (which is going to be re-released in the future as an improved model, probably with a different name). I don’t know about the D5100 – it might not work. Your Corona should work fine.

  • Kycas

    thanks for your answer…is helpful!!!

  • CotswoldPhoto

    Whilst the Ojecoco HSS feature works with the D300 (and thus also your 250T), I think the 5100 has video functionality, and that means Nikon will have disabled the D5100′s ability to work with Ojecoco’s HSS, so I do not think the D5100 will work, unless you remote trigger the shutter with a H430TX or a H550TRX (the HSS will then work if you do that). The D5100 only has a max shutter speed of 1/4000 anyway.

  • Kycas

    Thank you very much I did look everywhere I send mail to the manufacturer and this is the only place where I finally have answers.
    Thank..

  • Carl

    hello I need your help!!!!!! please!!!!!!!

    I have two H-550 and four H-430RX. work well at low speeds but when I try to run them at high speed the transmitters do not do the seem what he says in the instructions (manual) I use Nikon
    anyone can help me??
    what I have to do????

  • Carl

    thanks I already resolved
    I just have to increase the flash power at maximum :)
