FUJIFILM – EF-X500 – HSS Enabled Hot-Shoe Flash Announced



Fujifilm have announced development of the EF-X500 hot-shoe flash, providing High Speed Sync when used in combination with the new Fujifilm X-2 Pro mirrorles cameras, as well as optic wireless master and slave modes.

The low profile form of the EF-X500 is designed to suit the the compact and lightweight Fujifilm X-Series cameras, while still providing a solid Guide Number 50m (ISO100) at 105mm zoom.

The high end EF-X500 provide dust and weather sealing, as well as an external battery port.

The EF-X500 have also introduced optic wireless master and slave modes, allowing up to 3 groups (A / B / C) of remote EF-X500 flashes to be controlled off camera with TTL capabilities.

(Though unfortunately there is no wireless radio communication available a this stage).

FUJIFILM Corporation (President: Shigehiro Nakajima) has announced that it is developing a new high-end external flash “SHOE MOUNT FLASH EF-X500”. The EF-X500 allows users to expand their photography with high-speed synchronization and multiple flash TTL auto functions. It will be added to the premium camera “X-Series” system accessory line-up in May 2016.


Main Features

  • Low-profile, premium design that is perfectly suited to compact and lightweight X-Series cameras.
  • High-speed synchronization (FP) that supports the 1/8000 sec. shutter found in the FUJIFILM X-Pro2.
  • Multiple flash-unit TTL auto function unleashes users’ creativity by allowing them to control any lighting conditions.
  • Weather and dust resistant making it the perfect companion for the FUJIFILM X-T1 and X-Pro2, which have the same levels of protection.

    I am curious to see how this one turns out.

    Flash and mirrorless are still at odds and it is one of the last things where DSLR technology is still lightyears ahead.

    The two main issues I see (as an Olympus user, and I am interested to see where Fuji stand here):

    1. Processing of the TTL pre-flash and optical remote communication is slow and results in very visible pre-flash sequences.
    Where with current DSLRs pre-flashes are barely visible, these of mirrorless cameras are very prominent and can result in blinking. DSLRs were at this state back in 2004.

    2. It took me a while to even find this out, but mirrorless cameras obviously cannot use the red patterns DSLR flashes create for autofocus. Mirrorless need a white light to brighten the scene as AF assist.
    This unfortunately is way more obnoxious and where years of experience taught me that the red AF patterns are actually not distracting subjects very much, a bright white light definitely does.

      I think the slow preflash processing we see with Olympus (entire pre flash sequence takes 0.270 sec = more than 1/4 second!) is caused by the need to be backward-compatible with their older wireless-remote flashes, which date back to 2007! I’m going to hope Fuji can do better, since they don’t have to worry about being compatible with older equipment. Then again, it would have been nice if they had used that freedom to go straight to a radio-controlled system…

      • Thomas Geist 5 years ago

        Jim, that sounds plausible, but I am not entirely convinced. I rather think (at least the Olympus cameras) are churning along at their processor’s capacity.

        We always need to keep in mind that the processors of mirrorless cameras have to constantly serve the rear screen / EVF. You can clearly see how EVF display goes choppy when additional image modes are selected or when the flash executes its pre-flash communication.

        Again, that’s my Olympus experience but I guess it’s not much different for any other mirrorless system.

        Foster processors will hopefully help, even though they will get loaded with many other demanding tasks in future systems.

        • Jim Williams 5 years ago

          I’m sure that’s a factor (in which case the faster processor in the forthcoming Fuji X-Pro 2 might allow them to improve on the performance we get from Olympus.)

          However, I don’t know if processor overload really explains why Olympus optical wireless is so slow. The time base for signaling changes is actually very short, at 0.0005 sec,, and each full communication sequence (there’s one before the preflash and one before the main flash) takes a maximum of 0.0255 sec at the worst, which suggests that the processor actually is handling the coding pretty quickly. For vast majority of the total 0.270 delay, nothing is happening at all!… it’s just “blank space” in the signal pattern.

          I am guessing Olympus allowed these generous “rest periods” to give the master flash time to recycle after firing the control pulses and preflashes, so it will have full energy available to fire the main exposure flash. Other systems, as you note, work more quickly, so by starting with a “clean sheet of paper,” Fuji might well be able to tighten up these “rest periods” and get a faster optical system than Olympus. Still not as good as radio, though…

          PS — if anybody wonders where I got my timing data, see:

      Thanks for this information Thomas, I guess that means I won’t be parting with my Canon gear for Nightclub work anytime soon. Oh well.

    Hope it will the start for 3rd part hss/tll flash and triggers

      Hi Marco,

      If you may not be aware there is one small company already making the RoboShoot TTL triggers for Fuji.

      The new Fuji Optic Wireless may well help provide more of a framework for future radio systems to emulate now though.

      • Jim Williams 5 years ago

        I have a set of the Roboshoot triggers and in fact just did my first real shoot with them yesterday. They do work well (although there are some compatibility quirks with third-party flashes.) I wish Fuji had just given the developer a sack of money and bought out the technology to build into their future models!

    Optical wireless sound really outdated. Radio please!

    Looks like it was made by Holga.

    Why is a HSS strobe important for a fuji camera that can flash sync at 1/8000 with a normal flash?

    • Jim Williams 5 years ago

      Only the leaf-shutter Fuji X cameras (X100 series) can sync with normal flash at those high speeds… and the X100 cameras have a non-interchangeable lens. If you want a Fuji X camera with interchangeable lenses, you need to use one of the models with a conventional focal-plane shutter, such as the X-Pro 1, X-T 1 and X-T 10, etc. These have conventional X sync only at shutter speeds up to 1/180, a figure comparable with most other focal-plane-shutter cameras.

      The forthcoming X-Pro 2 camera will have a speeded-up shutter that offers X sync at 1/250… but that’s only a 1/3 stop improvement over the current models.

      So, if you want to use an interchangeable-lens Fuji X camera and you want maximum flexibility in blending flash with ambient light, you’re stymied until HSS-compatible camera bodies and flashes appear. Granted, there are limitations to HSS, but it’s really nice to have the option… so it’s good news for Fuji users that Fuji is finally catching up.
