PocketWizard FlexTT5 Transceiver For Canon TTL Flashes and Digital SLR Cameras

Adding: If you want a recommendation on whether to get the Flex and Mini or just 2 flexes, I'd suggest 2 flexes. First, because the flexes use regular batteries. And second because that gives you more options as you add lights and equipment to your set up (since the Mini can only be used on camera and not as a trigger for the flash). I do like owning the mini because it is so tiny and I hardly even notice it is on my camera. But both the Flex and Mini are very low profile and don't have the 'get knocked off' issues that the Plus IIs had.------A lot of the early reviews are before updates to download for this product had been made available (or used!). It works fine now. I have a very noisy 580EXII and both the Flex and Mini work fine with it. For me, dependability was about making sure the antenna was never pointed down. If you have any problem with the unit, typically it is because the antenna aren't parallel or are pointed at the ground. Just move either unit and you're fine. There are a lot of demonstrations, videos, and FAQ tips on how to really get these to work well.I'll give my thoughts and also make comparisons to the Radio Poppers since the Radio Poppers (RP) are the only competitor on the market able to do ETTL type of shooting (ability to shoot at fast shutter speeds). The Elinchrom Sky Ports and the Paul C Buff Cyberlinks will only trigger flashes manually and below the camera's synch speed - which is very limiting.I'm not going to go too technical into the specs and descriptions since those are readily available on the net.OverviewRight off the bat, I LOVE the design improvements over their predecessors, the PW Plus IIs. Both the Mini (a receiver that is tiny and fits on your camera's hot shoe) and the Flex (can be both a receiver or transceiver) are flat and sleek - they do not stand up or poke out annoyingly like the Plus IIs did. Even better, by incorporating hot shoes and shoe feet directly onto the units, you no longer have to worry about cords or velcro. This is wonderful - no more cords falling out or units falling off the flash. I don't have to listen to the pocket wizard dangling off a light stand as I move it around. The flash sits directly on the Flex:If you want to see a video of the new units and how small and easy they are, the PW people have a video on there site - check it out if you want to see these in use.By having both a shoe and foot on each Flex or Mini, you have the option of using them with other items that also require a hot shoe - such as the ST-E2 or another flash. By using it with the ST-E2 or another flash, you are given the further option of being able to adjust your Flash Exposure Compensation (FEC) at the camera rather than having to walk to a flash. If I were to give my one complaint about the new PWs, it's that they don't have that ability built right in to the Flex or Mini units (which I believe the Radio Popper Jr.s do - although the Jr.s cannot do ETTL, only manual like the Plus IIs). But you do NOT need to have the St-E2 or a flash on your camera - the Pocket Wizards work right out of the box with only one flash on a stand. This is a huge plus over the Radio Poppers, which require the extra expense of two flashes or an ST-E2 before they will do ETTL.The other huge plus about the new Pocket Wizards (and why I feel they are far superior to any other trigger on the market) is that they are a 'black box' - they have a brain that can be constantly updated. This means that new features can be downloaded for free as they become available. People are already finding new and interesting ways to use the Flex and Mini and configure them. And as new cameras are added to the Canon lineup, you don't have to worry about them not working. The Pocket Wizard people were given a stress test when the 5D MII came out and didn't work well with the new Flex and Mini - but in only a month or so, the team had provided an update to download that fixed the compatability issues. But it should be noted that the design of the 5D models (it's shutter is nearly the size of the sensor and that causes problems with synching) means they get the least out of the Flex and Mini features. But the Pocket Wizard people have fixed those issues - enough so that the engineers there are fully focused on finalizing the Nikon version and no longer have issues to address with the Canon models. Downloading the updates is easy - just plug the Flex or mini into USB and you'll have software quickly installed. That software provides all kinds of targeted configuration options that make the most of your particular brand of Canon. I'll go into specific issues/problems further into this.Finally, it should be noted that the PWs have a SUPER new feature - Hypersynch. Hypersynch allows you to configure the Flex or Mini to synch beyond the camera's synch speed - at speeds of 400 or faster. But this isn't just for Canon flashes - this is ALSO for ALIEN BEES! I know a lot of people bought the Radio Poppers after it was announced that they could do ETTL with the Alien Bees - but that turned out to not be true. The Radio Poppers could synch with a random Alien Bee now and then but it turned out that very few could actually do that. In contrast, the Pocket Wizards DO provide higher speed synching - though not through the full range of shutter speeds. Another huge advantage of Hypersynch is that it does not wear down batteries like ETTL does when synching at high shutter speeds. This gives you twice or even three times the battery life - which is important. Because of that, you can actually set your Flex and Mini to do hypersynching up to a certain shutter speed - and when that limit is reached, it will automatically use high speed synch. SMART!My ExperiencesI went out and gave the new Pocket Wizard Flex and Mini a workout on Thursday. I shot with ETTL and then with manual. I shot with shutter speeds as high as 1/6000 to really see what they could do.The big surprise was that I really liked shooting ETTL - the trick that was throwing me off was to meter for the background and then underexpose a stop - then I got all that drama I love but still had High Speed Synch (HSS) to add the right touch of fill light. I'd adjust FEC as needed. I started with a FEC of +1-1/2 for two reasons: 1) the umbrella would kill a full stop of flash power and 2) I was a bit closer to the subject than the umbrella and the flash would be metering for that closeness.I tried synching everything from 300 to 6800 or so shutter speeds and the lighting was soft and even on all the images. The higher the shutter speed, however, the less power out of the flash due to the demands of HSS - which led me to increasing the FEC to a full +2. Clearly, I would not be able to get the drama lighting on a brightly lit day - there's just no way the 580EXII has enough power when using the high speed synch features (which require continual bursts of the flash at high shutter speeds).The one big advantage that the Radio Poppers have is that you can adjust the flash output from the unit (hence, the camera). However, the RPs require an St-E2 or Speedlight - and I can easily put the Flex or Mini with one of those and then be able to adjust the power from camera as well. The RPjx has the advantage that although manual only, it allows you to adjust power of your strobe automatically. But then, in manual mode, I'd rather do the adjusting with shutter and aperture anyway so that isn't a big plus for me. I seriously do NOT want the weight of a 580EXII on camera with a Radio Popper strapped to it. For the same reason, I'm not going out and buying an extra 580EXII just to use my Mini with the 580 in order to adjust the FEC. I can walk to the darn flash stand happy.pngMy speedlight attaches directly to the Flex - which has a hotshoe on top - fabulous design!! No more cords to fall out and no more velcro. All I need is the Flex. It's also very flat and doesn't stick out annoyingly. No more PW banging against my flash stand or misfiring due to cords falling out.The Mini is very small - I can put my camera into my bag and leave the Mini on there. It's just a bit longer than a quarter and a bit fatter.I really like that the Flex and Mini are updatable and you can change settings with a USB cable. It means that as they get improved, I can just update them - this is really important to me since I want them to be continually compatable as I upgrade in the future.The Pocket Wizard people developed their own ETTL - they don't use Canon's ETTL. This Control-TL, as they call it, has a nifty little extra feature - hypersynch. Hypersynch allows you to synch at speeds up to 600, depending on your camera. With the 5D, that speed is 400. This is important since Hypersynch does NOT use HSS - and therefore it does not drain your batteries as fast and nastily as HSS does. You'll get 5x the amount of battery life by using hypersynch over HSS. You can configure your Flex or Mini to use hypersynch up to a certain speed and then HSS after that (e.g., hypersynch up to a shutter speed of 400 for the 5D before it tells the camera to use HSS instead).Also, and more importantly, the Flex and Mini can hypersynch Alien Bees! I'm seeing people Hypersynching up to 800 shutter speeds so the Bees very nearly have ETTL capabilities with this feature. This is ironic considering ETTL with Bees was the selling point with RPs which ended up not being able to perform as advertised. I get my Vagabond converter in the mail soon and I'll post examples as I try them. I have 3 Bees just waiting for a Vagabond right now. happy.pngWhat I really found surprising is that I liked using the ETTL and was more consistent with it on exposure than with manual. Huge surprise since I thought Manual just gave me more control for that drama. I used the ETTL as it was intended: fill light and not main light. But they can be used as a main light as well.Issues/Problems/RumorsThere were a lot of issues with the first release of the Flex and Mini - they do not work as well with the 5D as they do with cameras like the 50D, which has a much larger shutter compared to the size of the sensor. Also, the 580EXIIs are poorly designed and throw out a lot of radio interference. And it's really random whether a 580EXII will be bad or not - I am one of the unlucky ones who has a really noisy 580EXII and I've had to keep my Plus IIs dangling as far away from the flash as possible or they won't fire. Surprisingly, I haven't had as much problem with the Flex even though my flash sits right up on top of it. I'll keep shooting with it though and see if it becomes a problem. The PW people are actually working on a shield and flash holder for the stupid 580EXIIs. It's a shame that the PW people get a bad rap for a Canon QC issue.Another issue was that the 5D II came out right after the Flex and Mini - and Canon changed a lot of configurations in that new camera. There were reliability issues that the Pocket Wizard people addressed with downloadable updates and from what I've seen on the Flickr groups, the issues are indeed resolved.Although I had no issues with my tests on Thursday, I have had the Flex for 5 months now and the Mini for just a month. I have had reliability issues with the Flex and read up on the Pocket Wizard site what to do about it. Turns out that I wasn't watching which way the pop up antenna was pointing and so the Plus II I was using it with wasn't getting the signal. Basically, I do have to be careful to make sure that the antenna is pointing parallel or away from the second unit - just not right at it or at the ground. This was huge for me - after I started to follow that recommendation, I no longer had reliability issues. But until I read up on that, I was not feeling very confident of my Flex with Plus II combination. I had a LOT of misfires and was frustrated.So far, I am really happy with my Flex and Mini. One thing I do recommend is that if you don't mind the bit larger size of the Flex, it might be more useful to have two Flexes rather than a Flex and a Mini. There is only a $20 or so difference between the two.Choosing a TriggerDo you need ETTL enough to pay the premium price of $200+ per trigger (you'll need 2 to do OCF)? It depends on how much you'll be using them. If you just want to dabble and go out and play with it now and then, then no, I don't think you need the Radio Popper or Pocket Wizards. Or, ideally, you can get two used Pocket Wizard Plus IIs for much less now that everyone is selling them off. The Plus IIs will give you full manual control and really teach you about light. If you shoot adults or teens, you'll love the ease of use and versatility of being able to use ETTL.But for the price of a used Plus II, you can get the Paul C Buff triggers or the Elinchrom Skyports. Those will give you manual but not the range of the PWs (though I doubt you're going to be using off camera flash from a distance of over 10 feet from the flash unless you do weddings).Comparison of Flex and Mini to Radio Poppers:Advantages of Pocket Wizard Flex and Mini:- attaches securely to camera or flash - no cords, loose parts, velcro, or anything else.- upgradable: constant updates make it better and better- hypersynch allows you to maximize flash recycle time and batter power. You can set at what speed the PW goes from Hypersynch to High Speed Synch.- hypersynch Alien Bees above your camera's synch speed.- does not require additional purchase of a second 580EXII flash or an St-E2. It's Control-TL is built in (though they can be bought and used with the PW if you want to do that)Advantage of Radio Popper:- Radio Popper Jrs can adjust the flash output on camera- more reliable?- Can be used on Nikon or Canon - not brand specificWish List:- adjust FEC directly on the Flex or Mini unit- a beep that tells you if the flash fired or not (stupid Canon flashes)

The reviews from 2009 or so are definitely from people who were understandably disappointed that these expensive devices barely worked with Canon's newest flashes like the 580EX. Even with the latest firmware (6.0), the RF sock/sweater that is included to work around the problem is still absolutely necessary on these flashes to get any reliability beyond 30 feet when using the small MiniTT1 transmitter. Unfortunately the sock also blocks any IR signal so you can't program the flashes remotely. The sock also covers the controls making it more difficult to adjust the flashes when they are mounted in inconvenient places like from roof rafters. The sock is a desperate solution but it does work.Once you have the sock on, reliable distance extends well beyond 150 feet, as far as my less noisy 550EX. This is no longer an issue in my experience and in my opinion you can disregard the many complaints about distance now.The "documentation" consists of videos, a "Quick Guide", some firmware notes and a clumsy Wiki on their web site. It refers to step-by-step instructions that I've never been able to find. In high pressure shooting situations you need a quick reference guide, not a 10 minute tutorial video teaching you how flashes work.The poor documentation has led to misunderstandings about Hypersync. How it works depends greatly on the type of flash you're using. With a fast strobe like a Speedlite, it will allow you to sync a TINY bit faster than regular sync. For example with my 1D Mark IV I can get the flash to sync with just a small black band at the bottom of the frame at 1/500. This is a great feature for when I'm using it for fill flash since my subject will almost always be outside of the clipped area so the ambient light completely fills it in. Any faster shutter speed will give me a larger clipped area but it still may be usable in some situations.That's all that Hypersync can offer for fast flashes but it's much more useful for slower studio flashes that will put out light for longer periods. Syncing up to 1/1000 is possible with some larger flashes. Unfortunately the documentation doesn't make this clear enough for some users. You can use the utility to set the FlexTT5 to use Hypersync for all shutter speeds to see its effect for whatever flash you're using.Some people are claiming to be using Hypersync with their hot shoe Speedlites up to 1/8000. They don't realize that for these fast flashes the FlexTT5 is falling back to the pulsing HSS mode at these shutter speeds. The shutter speed that activates this is adjustable. The utility lets you set the lowest shutter speed that you want the FlexTT5 to stop using HyperSync and start using HSS i.e. when you feel the black band in HyperSync is too large to make useful photos.The FlexTT5 does improve the performance of HSS by reducing the number of times the flash pulses during a shot. You can test this by measuring the recycle times after an HSS flash with the FlexTT5 and with a cord. While the exposures will look identical, the flash will recycle more quickly with the FlexTT5 (especially at fast shutter speeds) showing that the flash used less power. It's surprising that Canon flashes (and Nikon's too apparently) are wasting this much power in HSS mode for no reason but clearly that's what's happening.Some people claim they get a stop or two more power from their flash in HSS mode. I haven't seen this and can't confirm it. I may not be using the HSS system at its limits.I've found it's very important to hit the TEST button after setting everything up. Sometimes the sync will be wildly off -- even shots at 1/20 will have a black band in them. I hit the TEST button and everything's back in sync. Always take test shots before you start taking important shots and don't hesitate to hit the TEST button if the sync isn't working.It would be great if the Flex system allowed you to adjust the Canon flash settings from the camera menu like you can when the flash is mounted on the hot shoe but that's not implemented (the camera says it doesn't see a Canon flash in the hot shoe). To change the power when a flash is in manual mode, you have to go to the flash (where ever it's mounted) pull up the RF sock, punch in the change, put the sock back on, then go down and test the change. Very tedious and time-consuming. Radio Poppers support adjusting manual power levels remotely.Naturally you aren't allowed to use a flash on a FlexTT5 as a master to send Canon's IR signals to slave flashes either. The flash won't work in Master mode so plan on buying a FlexTT5 for every flash you intend to use.Some people are complaining about the expensive button batteries in the MiniTT1. Buy them in bulk. I bought six for $11. I have found them locally for $10 EACH! Quite a savings.

Got TT5 mainly for HSS purpose, can't say a bad world about the performance along with my speed-lights however when I use these in studio with my strobes I heaving a problems with connection, from some reason Im loosing connection quite often which is very annoying, I done alle the updates but no luck, I looked online for solution and have no found any solution, I still keep these is my case for outdoor work however in studio Im back to my Plus III

Great product, easy to use, very stable and totally cool to be able to just spin that shutter dial beyond max sync speed and (on my camera) all the way to 1/8000 second to block out all ambient light. I am very happy with mine and have just ordered a third one.One drawback though. The build quality is great except the hot shoe which is in plastic. A heavy speedlight on top of the Flex TT5 makes the plastic hot shoe the weakest pivot point and I have just broken the TT5 plastic shoe when my softbox was gently laid down by the wind. The weight of the speedlight alone made it break, no harm done to the speedlight though. The hot shoe is simply to weak to secure it properly. From now on I am using the 1/4" screw to secure the Flex TT5 which is working way better.

Already have one of these and they are great pieces of kit but needed another, delivery was quick and the price was also very good. Unfortunately the item was defective and had to be returned , the return process was very easy and I am now waiting for the money to be refunded.

Does what it's meant to. They are ok but have too many options and they stop working too often in a professional environment. Have opted for Yongnuo instead.

I needed a good and reliable transmitter and receiver to shoot the evening part of the wedding with off camera flash. I had a pair of cheep Chinese ones but they used to misfire a lot so could not really rely on them. I was extremely happy with both PocketWizard Trasceiver and the transmitter. I would highly recommend it to anyone who needs to use off camera flash, especially for the wedding or any other important event photography.
