New TTL flash gun trigger for Nikon


Strobist reports about a new TTL remote for Nikon and Canon DSLRs. The "speculations" came from the Strobist flickr group. Here are specs:

  • TR-331 is using FSK 2.4GHz frequency channel, 15 specific channels .
  • Operating distance range is 65M or above.
  • The display is protected by coating; it’s not easy to get scratch.
  • LCD is showing “Channel”, “Battery life” and “Function mode”.
  • Multi-control is available.
  • Through the camera to send the data
  • Compatible with all Nikon DSLR cameras.
  • Compatible with Nikon SB-900, SB-800, SB-600, SB-400 flash gun.
  • Support all of the shutter speed, up to 1/8000 sec.
  • Available to use on the studio light through PC socket.
  • Transmitter stand-by time: 1000 hours above (CR2 lithium battery)
  • Receiver stand-by time: 400 hours above (CR2 lithium battery)

This is the manufacturer's website. I think they will be selling those through eBay, since they have already setup a brand new eBay online store. The expected price will be less than $200.

    Range, 65m or above? Do they mean it goes sometimes even further, or it doesnt work within 65m? 😛

    • Tobi

      LOL Thats what I was going to comment on too 🙂

  • Nau

    looks like a fair price if its a good product

  • Viktor

    Bad news to PocketWizard. 😉

  • Harry Couvert

    2Q’s: does this work with groups (and how many) and as one transmitter for multiple receivers?? Curious. If it only works in pairs, wait for PWizard because that will work as a flash master for multiple flashes in groups.

    • I’m fairly certain, considering how radio waves work, there is no limitation on how many receivers can be triggered by one transmitter. In fact, it would be more difficult to enforce a limit than not….

  • Incognito

    Pocket wizard is now a year late from when they wanted their syncs released! Hurry up PW!

  • f/2.8

    Very impressive features set.

  • Harry Couvert

    Delays are because of the difficult/complicated Nikon signal.
    Canon seemed a lot easier to ‘translate’.
    Im guessing they dont get a lot of help from Japan either….

    • Incognito

      I think the delays are because canon’s units had major problems with inconsistant rf signals. I read nikons system was actually easier but delayed cause they wanted to fix canon models first. I missed out on a whole wedding season because of this delay!

    They should have made it work with AA batteries. Working with studio strobes – interesting…

  • lox

    Wow, 1874 views on their ebay store and not a single item to sell 🙂

  • Stan Strembicki

    This new unite looks great and seems way cheaper than the new Pocket Wizzard, but the email address on their WWW site does not seem to work so I wonder if its some kind of fly by night outfit.

  • Kevin

    Please do not buy the pocketwizard TT1 or TT5 if it’s released for Nikon. The product is very poorly made and prone to being damage extremely easily. The hotshoe connector is flawed and likes to pop out making them useless.

    I went to radio poppers myself and couldn’t be happier.

  • zeeGerman

    Who needs wireless TTL? Especially for the low budget market, I believe a product with the Radiopopper JRx approach would make a whole lot of more sense.

  • Harry Couvert

    ZGerman: ever worked with more than one at the same time?

    • zeeGerman

      Yes, all the time. And that is exactly why I’m asking. Manual mode for the flashes and camera is essential for complex situations. Depending here on the thoughts of a Japanese engineer several years ago, seems to me rather uncomfortable.

  • Adam

    I ask them (pixel) about any distributors in Europe and got replay, that first orders they will send to

  • Kevin

    Mleh the radio poppers are already extremely amazing. I’m able to get range at 110m on my Px1 system. Also I am controlling upwards of 8 different speedlights using one radio popper controller. I personally love how the radio poppers are simply an IR tranceiver in many ways.

    The hotshoe type wireless flash triggers are always going to be prone to the hotshoe popping out. The pocketwizards in general though have very very very poor construction overall. I mean they even feel cheap in your hands.

    The three big knocks against these “pixel” controllers are really simple.

    1) we make it in china cheap.
    2) CR2 batteries? WTF are you kidding me. Yay to $$$ batteries.
    3) selling your products solely on ebay?

    In short I think radio popper right now is ahead of the competition. I’ve had no issues at all with their product and I absolutely love them. I had been using TT1 and TT5 with my old Canon setup for some time but sheesh I went through 4 TT5s.

  • CS

    Does someone work for Radio Poppers?

  • Kevin

    Nope I don’t. But I have used a variety of different products over the course of the last 3 years, whether they were made by pocket wizard or elinchrom, etc. I find the radio poppers are simply the most reliable out of the bunch. The only downside to the radio poppers is the available can be some what touchy. I waited 3 weeks for mine.

    If you do buy the TT1 and TT5 you will be disappointed. Seriously I had one TT5 break when I tightened a 580EX II. It snapped into place and the hotshoe came up.

    • zeeGerman

      Radiopopper rocks! I just wish they would have gone with different batteries for the Jrx.

  • VD

    I noticed something: shouldn’t the trigger (the one that fits on the camera) have the extra pins on the hot-shoe connector for TTL to work? Or does it need the sync cord connected as well?

  • LGo

    What I would really like to see is the new Nikon SB700.
