Take control of both on- and off-camera lighting with the bare-bulb Qflash TRIO Flash from Quantum, which features a built-in FreeXwire radio system for wireless operation from up to 500' away and an output rated at 80 Ws. This version is compatible with Canon's E-TTL / E-TTL II metering system and has a guide number of 105' at ISO 100 with the QF60 reflector, which also provides coverage of about 35mm on a full frame camera. The head can tilt upwards 90° as well as rotate both left and right 180° for full bounce functionality.

The flash runs on Turbo series battery packs, which can provide a recycle time of just 1.5 seconds at full power. The unit also has a variety of sync settings, including slow, high-speed, 1st and 2nd curtain. Additionally, options such as auto fill ratio enable simple usage for fast setups in changing lighting.

    Quantum Instruments QF8 reviews

    Qflash TRIO Flash for Canon Cameras is rated 4.3 out of 5 by 34.
    Rated 4 out of 5 by from Great power and recycling time I am a wedding photographer who prefers natural light but I use the Quantum for receptions, ceremonies and a touch of fill when backlighting outdoors. I love that it recycles so quickly enabling me to fire off several shots for a ceremony. Though it is a large unit, the battery is strapped over my body which lessens my load on the camera. I use it with the reflector (diffusers removed) bouncing it off the ceiling for receptions and the effect is quite natural. The only downside is the connection to the camera hot-shoe which seems a bit loose which concerns me for turning the camera to a vertical orientation.

    Rated 2 out of 5 by from Trading mine in Tried using this for outdoor portrait work off camera. It is light, easily transportable and puts out enough light to get the job done when it works. I found that it is completely unreliable. Too many adjustments. Takes too much time to try and figure out the correct settings. I found that it often simply won't fire. Set it on manual. Works for a few frames. Stopped working. Couldn't get it to work. Tried switching modes. That helped. I found the settings not to be accurate. Often overexposed even when dialed down. Simply too glitchy and too inaccurate. Hate the hotshoe. I agree with the other reviewers, it is not rocket science anymore to create a decent hot shoe. On camera it comes off too easily and is difficult to tighten adequately.

    Rated 2 out of 5 by from Trio Flash OK I have had this flash for a little less than two years after a short time I had to return it because the mounting mechanism failed. Quantum did repair it at no cost ,however for what this unit costs its totally unacceptable for the poor design flaw to have made into production . I have no issues with its functionality lighting wise ,but I would not reccomend buying this for the poor quality of the construction of the mounting mechanism ,which in the end negates any of the benefits of good light quality & functionality. It needs to be redesigned

    Rated 4 out of 5 by from Somewhat satisfied Love the power, functionality could be better, design has some flaws, the hot shoe connection that is frequently mentioned to mention the larges, the diffuser is somewhat Mickey Mouse, it fell of a couple of times.. Bought the Turbo 3 at the same time, fantastic. If you do event shooting get this flash and battery, you will not regret it, more power that the 580EX and cycling is not an issue. Bought with the rebate from BH, have yet to receive one and the other they didn't give because I forgot to buy the cord. Wasn't clear and the company Quantum are not what I'd call friendly.

    Rated 1 out of 5 by from Do not buy this unit! I am a professional photographer heavily invested in Quantum having 2 T5D-R and 1 X5D-R units with several batteries. This is the first substandard piece of gear that I have purchased from Quantum. I wish I had taken the advice of several user reviews regarding the Hot Shoe mechanism which is pure junk. Using this flash, the unit will not tighten sufficiently to enable the QTTL and Auto Fill features--the screen says that there is no camera attached. I used it twice successfully in my Canon 5D, but it literally fell out of the 5D II which has a little more clearance in the shoe. It rocks back and forth on both cameras and will only make enough contact to use it in the manual mode while not communicating with the other Q-flash units. Luckily, I had my trusty Q-flash adapter and separate transmitter to get me through the gig with an assistant and pole mounted T5D-R. I am sending this unit back for a so-called fix that Quantum has come up with. Until Quantum engineers a proper attachment, stay away from this expensive piece of junk. If this was engineered in Japan like the 580 EX II, it would be a good product. I am holding off on buying the Command Pilot until I am assured that Quantum has a better contact shoe mount mechanism. Your equipment is only as good as it's weakest link, and this one is lame.

    Rated 3 out of 5 by from Good light, poor constructioin As has been mentioned several times, the build quality is poor. I've taken both my Trio and Pilot in for repairs to the hotshoe. I've been very careful with how I handle the gear, but the same damage still occurs. Very frustrating. Now, the upper casing will not rotate and is cracked at the tightening knob for the difusser. Grrr. The unit has never been dropped or mishandled. The light is nice to work with, but given a quality alternative, I would definately consider using another brand.
    Date published: 2012-02-08
    Rated 5 out of 5 by from Keeps going all day as advertised I bought this after literally melting down 2 Canon 580EX (not Mk2) flashes when using CP-E4 packs. I shot 800 frames inside 20 minutes during a fashion show with this one with no overheating at all. The Turbo SC battery just kept going. I am now convinced that this will not melt like the 2 Canons did - if you need to shoot rapid fire, this is the one to get. The only downside is the terrible design of the hotshoe mount. I leave it mounted permanently to an extension cord on a flashframe, so its manageable. I would worry about it if I had to re-attach it frequently. The quality of the light is superb compared to the 580EX - to do better you'd need a studio strobe and softbox. The best hotshoe flash I have ever used - by some distance. Expensive up front - but a lot cheaper than frequent meltdowns (or slowdowns/shutdowns with the Mk2 580's)

    Rated 3 out of 5 by from Might be on an auction site soon ! Look, as a portrait photog, I researched and noticed the praises Qflashes receive from numerous sources. I was looking for a flash that would fall in between my Profoto studio lights and my 580EX Canon shoe mount that would give me versatility, more power and customization. This flash does provide all that but at the cost of convenience (which might not be a big deal to some). Im not going to write its praises as far as light quality goes. Its pretty good as you can figure out on your own. Im only going to write my severe dislikes...which may not bother you but here goes: 1) It feels like a toy. Very hollow sound, cheap plastic finish, not the thick plastic used in most applications today. 2) The shoe mount is an absolute joke. Has a simple little useless knob which tightens the base of flash to hot shoe. Very top heavy and feels like at any moment it will fall off. I find myself checking the connection over and over and over all day. Its bordering on OCD at this point. For all this money, you mean to tell me Quantum cant redesign a modern hot shoe connection ? Do we as consumers need to mail them a Canon 580EX II to they can emulate its security and weathersealing capabilities?? This is just not acceptable to me. Maybe you will be using it off camera and are not affected by it. 3) Guide numbers and my own test using light meters show me this flash is not much more powerful that the 580EX in the real world. Of course power isnt its selling point...I feel its ability to manage several off camera flash units and its versatility are...but regardless, I would have liked more punch to it. I mean whats the point of carrying around a 3 lb Quantum Turbo battery attatched to my side if it cant solidly outpower the rechargeable AA batteries in my Canon 580EX ? Anyway, If your buying this your probably already a Quantum user and dont care about my critism. Me, a first time Quantum buyer, dont see value in this $1k plus set up (factoring in flash and battery pack). Just my humble opinion
