elv0000 says:

Firstly apologies for they delay in getting this up.

A while back Pixel brought out their upgraded version of the very popular YongNuo RF-602 2.4 GHz radio trigger, called the Pawn TF-361.

They have now released the TF-371 Soldier which is an upgraded version of the 361 (Pawn), the main added feature being separate multiple flash groups A, B, and C, allowing you to quickly switch on and off each light (or group) from the camera, for fast set up etc.

Pixel Soldier TF-371 - With 3 Groups

Pixel TF-371 - Back

The main upgrades the Pixels have over the RF-602 -

- Multiple Groups - A,B,C
- Higher Sync Speed (often 1/320th!)
- A lock down ring on the transmitter with locking pin
- A lock down ring on the receiver
- An On-Off switch on the Transmitter
- An Accessible On-Off switch on the Receiver
- Standard 2.5mm miniphone plug
- Higher trigger voltage 36 volts vs 12 volts
- Longer battery life - 10 x Longer!


Some features both the TF-371 and RF-602 share -

- Most Important, they are reliable :-) great rang no misfires etc
- Also operate as a simple shutter remote control
- Flash wake up feature, wakes compatible flashes from sleep mode
- 16 Channels


Groups -
Pixel TF-371 - Tx Group SelectionPixel TF-371 - Bright Ready Lights

The main added feature of the TF-371 is the multiple groups.

The advantage to this is it allows you to quickly turn on and off different lights straight from the camera so you can meter them separately without having to reach each light to switch them on and off.

This can be a big advantage using a light meter or not, it’s great to be able to quickly see exactly what each light is doing individually.

Offcourse this could also be used in many different applications, like setting a number of lights around a room or dance floor etc and just turning on the ones you want at a particular time.

Tx Switch -

First impression ... why not just a simple manual switch? But it probably does have its merits, because even in the pitch darkness you can't get it wrong! You can't miss the button and you can't miss the resulting group selected!

The Rx on the other hand does have a simple manual switch, but it would be useless on the transmitter as it would be too hard to tell which group/s you had selected (works fine on the receiver though where it’s not changed much)

Pixel TF-371 - Tx Group Selection

You simply press the button on the Tx once and all groups are selected (3 red lights) then keep pressing to scroll through -

- A only
- B only
- C only
- A and B
- A and C
- B and C
- A, B and C (all)

Even when turned off and back on, the transmitter remembers the last group selection. To see which groups are currently selected just press the button once and they show on the Tx, press again to scroll through changing them again.

The other good thing is the receivers have a nice big light on the end which can be seen from the side or the top. This glows bright green for a few seconds on half press of the camera shutter letting you know exactly which flash is going to fire (on full press).

Pixel TF-371 - Bright Ready Lights

So that’s the groups, very simple to use. Maybe something you wouldn't think you would need all that much, but the ability to quickly turn lights on and off from the camera is a great convenience.


Sync Speed -

I'll go straight into this one now because this was a surprise and may be quite an advantage for some.

Even on 1/250th sync speed cameras the TF-371 are getting an almost complete frame at 1/320th!

Pixel TF-371 - 1/320th sync!

Even at 1/400th there is still a usable amount of frame left to work with!

Many of the previous inexpensive triggers would start showing more shutter than that 1/320th result above at 1/250th and it’s common to go back to 1/200th to be safe.

This may also be a big help to 5D users that are often getting 1/160th at best. I haven't tested a 5D/II but that would be very good to hear if anyone tries one please let us know!


Lock Down Rings -

Unlike the RF-602 Pixel has added Lock Down Rings to both the RX and TX

Pixel TF-371 - Base with Screwlocks

Transmitter -

Pixel TF-371 - Tx Base

This one is no comptetion - the RF-602 Tx (shown right) has nothing holding it in place on the cameras hot shoe except the little bit of spring tension on the shoe itself. Depending on which camera model this may or may not be a big issue.

The Pixel has a locking ring and locking pin that locates in the hotshoe. It can't fall off and won’t move off the contacts causing misfires.

Receiver -

Pixel TF-371 - Rx Base

I'm actually in 2 minds about this one, the RF-602 doesn't have a locking ring but that allows the receiver to be a bit more compact and also keep the flash a little lower/closer to an umbrella if used on the shoe of a flash. And I would only attach them to a swivel via the screw thread in the base as the plastic feet often break.

The locking ring on the Pixel is also too small (diameter) to get your fingers around to tighten in many places anyway (ok on the camera hotshoe). This is the same with all their locking rings.

On a base stand I can not get to the ring anyway, though I was able to tighten the locking ring first so its tight to slide onto the stand to start with. That works ok and is much more secure than the RF-602 with nothing securing it, but the flash is not going to fall far on a small stand anyway.

Pixel TF-371 - Small Locking Ring


On Off switch on the Transmitter

Pixel TF-371 - Tx

I'm not sure if this is a big deal, but the RF-602 has no On/Off switch (like most of the cheap triggers before them). This means they could be wasting batteries if the test button accidently gets held down in your bag etc. They could also be draining some battery power all the time on standby too. But the Tx battery use is so low I'm not sure its an issue.

The Pixel has an On Off button, just hold the group button down for 2 seconds.


Accessible On-Off switch on the Receiver

Pixel TF-371 - Power Switch Access

Pixel has placed the On-Off switch at the end of the receiver where it can easily be accessed when the flash is in place. Where as the RF-602 switch can not be reached with many flashes on the shoe.

This one I am surprised to say is a big convenience. Using flashes like the 580ex straight on the Rx hotshoe because they don't have a sync port (same with 430ex etc) and the ability to just turn the receiver off leaving the flash in place just feels like a luxury. Nothing worse than locking the flash down on the 602 just to find you didn't switch it on first grrrr!

If only connecting via a sync port though this is a non issue.



Standard 2.5mm Miniphone Plug

Pixel TF-371 - Standard Cord

This is another one we’ve been banging on about forever. Just like batteries it would be so much easier if everyone would just used the standard 3.5mm headphone plugs (you can pick up cords and adapters for anywhere).

Pixel have used the 2.5mm miniphone plug which is a step forward, but at the same time (and I hate to say it) there is nothing really wrong with the proprietary plug on the RF-602 in that application.

Both cords are widely available on the net and neither are going to be found easily at your local stereo dept (or camera store unless you’re really lucky). Still +1 for Pixel, but in reality I don't think its any great issue with the 602's either.


Higher trigger voltage

Pixel TF-371 - 36 volts
YN RF-602 - 12 volts

I will have to check on this again, but when I enquired a while ago they were the specs given. This just means more monolights mainly will be compatible with the Pixels. Older speedlights (like Vivitar 283 for example) are well over 200 volts trigger voltage and would not be usable.

This is also just about the only reason I would buy any of the older 433Mhz ebay triggers (including dare I say the Cactus V4) over RF-602 or the Pixels etc. These are just a world ahead otherwise in range, build and reliability etc.


Longer Battery Life - 10 x

Pixel TF-371 - BatteriesPixel TF-371 - Batteries

Receiver -

Both TR-371 and RF-602 use the same standard AAA batteries for the receivers. A+ for Both!

Pixel claim to have 10 times longer battery life though. I can't confirm or deny that but they are pretty clever, and squeezing battery life and sync speed out of no where is what they like to do. See the battery pack comparison here for example -
photography-on-the.net/forum/showthread.php?t=896780

Transmitter -

They both get a Fail here for not using standard AAA batteries.

Around here at least, the CR2032 button cell used in the Pixels are cheap and available in any battery dept., where as the CR2 in the RF-602 are not cheap and only available online.

The transmitter draws very little power though so replacing them is not something that needs to be done that often.

Channel Selector -

Also note in the image above the channel selector is hidden/protected in the battery compartments. At first I though that was a bad idea, but considering they are very seldom changed it’s actually quite good. It’s only the groups that are changed often and easily accessible.


Shoe Clip & Protector -

Pixel TF-371 - ReceiverPixel TF-371 - Cord

Another nice feature of the Soldier is they come with a hotshoe protector cap, and also a stick on shoe clip to mount the receiver on when it’s being used via a sync cord. These are great someone should be selling them separately.


Transmitter Sync Port?

Pixel TF-371 - Tx

This is the one place the Pixel falls down, there is no sync port on the transmitter of any kind. This was easily fixed by adding a hotshoe adapter to the shoe of the transmitter with a port in it like this - www.flashzebra.com/products/0128/index.shtml but it seems crazy they would not have a sync port built in. The RF-602 is ahead on this one with a screw lock type PC port built in.

A sync port in the transmitter is used to connect directly to a light meter or to the cameras PC sync port when there is already a flash in the cameras hotshoe. Using an additional hotshoe as stated above does provide a solution if needed though.


Range

Pixel TF-371 - Range

It was pretty much equal here, at about 110m line of sight they both started misfiring, if anything the Pixels got a few more fires at the extreme. That’s ridiculously far in any case (the image is not wide angle, that’s a wide culdesac and I'm back further in the bushes with a 70-200 lens).

Call that even and great range from both!


Body

Pixel TF-371 - ComparisonPixel TF-371 - Rx Base

I have to give the advantage to the RF-602 Rx here. They are just a slightly smaller but tighter neater package. Its things like standard plugs, batteries, and locking rings etc I mentioned earlier that take up extra space though, so I can't complain about a bit of extra size if its contributing to greater convenience. They are both still a fraction of the size and weight of PocketWizards.


Shutter Release

I'll have to get back to this one as this was an early sample and I didn't receive the shutter cords. From what I can gather though Pixel supply all the Canon or Nikon (or Sony/Olympus) shutter cords for each camera model so you just buy one Canon trigger compatible for all Canon cameras instead of just your specific camera model. I’ll have to check back on that though. Otherwise the shutter release is the same function as the RF-602.


Summary

Well it was never really a fair competition, Pixel have had the luxury of building on what was and still is the first great budget flash trigger (in the RF-602).

The TF-371 groups are obviously a nice feature but the other things I like are the extra sync speed, a transmitter that’s firm on the camera hotshoe and being able to use the Rx power switch without pulling the flash off all the time!, as well as the big green ready lights on the receivers.


Price & Availability

Only when I started doing this review I realised the TF-371 have still not yet reached ebay etc. There are plenty of the TF-361 (model without groups) on ebay from about $50 a set (with shipping).

So as with Pixel’s battery packs and TTL triggers its a matter of waiting for a good seller to pick them up and sell at a good price (which would be comparable to YongNuo).

Gadget Infinity have the ETTL triggers now for $150 which is bargain (deal extreme price) but from a good seller with good service, so hopefully they will pick up the TF-371 as well -
www.gadgetinfinity.com/product.php?productid=17460&ca...


You can purchase the TF-371 direct from Pixelhk on ebay now to but I'm not sure of the price as they have put all their prices up considerably now over the resellers rates.

The other models availabe are -
TF-371 – Canon
TF-372 – Nikon
TF-373 – Sony
TF-374 – Olympus & Panasonic 4/3


Hacking

Pixel TF-371 - Rear Curtain Sync

Just for interest, this is how the rear curtain sync hack is done for Canon. Simply attach the transmitter to an optic slave and place that in front of a flash on camera, with the camera set to rear curtain sync. The transmitter will then trigger the radio slaves on the rear curtain.

This is also the same hack used for "hypersync" high speed sync. Just use an ETTL flash on camera set to HSS. Set any manual slaves to full power and shoot at any sync speed. The results may vary, and I haven't tested with these triggers yet. These hacks can be done with RF-602 just the same.


Hope this review was helpful and thanks again to the people who have been waiting.

Nice write up Elv - do you know if the two are compatible? If so that would be very handy. Instead of buying more RF602's just buy a couple extra of the Pixel units and add them into the triggering group.

elv0000 says:

Thanks dpj,

As far as we know they are not compatible unfortunately, I didn't try all channel combinations (I think thats 256 of them :-o) but they are not going to work in with the separate groups anyway.

I don't think existing RF-602 owners would be rushing out to buy them unless your after the groups feature (or you have the loose Tx).

But they will be hard to go past for new buyers once good sellers are available with price comparable with the 602's.

Snap! I just received my package of Pixel Soldier TF-372s (Nikon version) a few minutes ago.

According to the manufacturer, the Pawns (TF-36X) are not compatible with the Soldiers (TF-37X). However the different models within each series are compatible with each other, e.g. TF-373 with TF-372. Useful if you have a Sony camera with Nikon flashes (or any other combination).

Interesting, thanks for the review.

They arent available on the PixekHK eay seller yet.

I think they would be an excellent option and an improvement on the YN, if it weren't for the RF602 getting to market sooner I might have been interested. Bit like the Xbox/PS3.

Id buy one of those sticky hotshoe clips too!

SeedyBee2008 says:

The TF-371 Soldiers are very nice units.

The internal assembly is good, except for one weak point. The cradle for the CR2032 battery in the TX is assembled with the other components in an automated solder-bath. To get solder to the right place, a hole through the circuitboard is used. This can produce a slender mushroom stem. When the user tries to remove the battery, it can place strain on that stem and fracture the joint.

Fortunately, it is easily repairable with a fine conical soldering iron. It's worth taking care when extracting the cell.

SeedyBee2008 says:

The selection of different groups or combinations is very smooth. For those who use light meters, it is particularly useful. Buy a second transmitter for hand-held use.

Thanks, Elv, for a valuable review.

elv0000 says:

@ Seedy - hopefully that was an isolated case, I don't think I could pull the battery holder off the circuit board on this one without breaking it first.

@ Kris - yes the hotshoe clips are a perfect fit on the RF-602 as well even without any locking ring on the foot. They are also perforated on the edges to wrap around curved surfaces. 3M tape too so its not some cheap and nasty goo.

@ Selbosh - Thanks for the compatibility info. Look forward to the Nikon review. The Sony thread is interesting too, they have to be easy to please owning a Sony though. :-)

Tx elx000!

but...

the last time you posted a positive review (of the Pixel battery pack clones) their price went up 30%. I was very lucky to get 3 at the original price.
These do sound good. Groups, including Seedy's point about external metering, sound handy. With 602s I become a TAF - Thought Activated Flag - while metering for ratios. Tx

Pixelhk have listed the TF-371 Soldiers for Canon and Sony on ebay.

cgi.ebay.com.au/Soldier-Flash-Grouping-Shutter-Remote-Con...

A little steep now but their listings are always above the resellers prices. The good news there is they are only a $1 more than their TF-361, so 371 prices should end up around RF-602 prices too.

@ LayerMask - you can still get the battery pack for $49.95 on Deal Extreme and other ebay sellers. I think Pixel just lifted all their price as retail sales is likely not their prefered business.

@ Celtic - Yes the Phottix is a big step forward, but at the same time I would not trust a flash on top there anyway, It would be great to use an ST-E2 on top for focus assist though. I think they will always be in a higher price range though too.

Thanks Elv - I've been waiting for this review of yours for ages :)

Sounds exactly like what I'm looking for as I love the group ability of my skyports and the hotshoe and reliability of my RF-602.

I've been told my Pixel that these are not compatible with Yongnuo's so that's closed (and even so, how would you manage groups?).

Might consider upgrading my RF602 when prices are right for the group feature.

microbug_de says:

Nicely done!

Having bought and tested the Pawn (TF-362) for Nikon, I found it interesting, but performance-wise a mixed bag, since there are delays in operation - the RF-602 does not have this delay values.

The other thing that kept bugging me is the spereate treatment of trigger button and hotshoe pin on the trigger. Does the 37x do the same thing?

BTW: Pixel does not list this item on their page and at ebay it is hard to find, so I have to wait a bit for the Nikon version to be available.

@selboshII: are they backward compatible with the Pawn aka TF-36x?

elv0000 says:

@ microbug_de - There is no delay at all with the TF-371 Canon version, its just like using the RF-602.

SeedyBee2008 also mentioned something like a delay with the 363 (non group model) Sony version, but not having experienced those myself I don't really understand the delay situatuion.

I'm not sure what you mean about separate trigger button and hotshoe pin either?

But Selbosh II has the the Nikon version TF-372 now for review, so maybe he can shed some light on the Nikon situation.

He also said they are NOT compatible with the TF-36X ect, but they are compatible with the other brand TF-37X units.

fuzzy cart [deleted] says:

Microbug: The company told me that Pawn TF-36Xs and Soldier TF-37Xs are not compatible.

I've found that on the Nikon D700, the TF-372 will give a clean image at 1/250s while the RF-602s have a slight feather at the edge of the frame at the same shutter speed. I'll let you know how they compare on the D40 too (RF-602s give up to 1/800).

What's the different between TR 37X and TR36X?
ages ago (permalink)

view photostream

elv0000 says:

The TR36* or "Pawn" are the first version. The TR37* or "Soldier" are the latest version.

The main difference is the Soldier have 3 groups, so that you can turn each light (or group) on and off individualy from the camera. I think the battery life has also been extended.

I'd be a bit concerned about the earlier Pawn as a few people like microbug_de above have said there has been some type of delay in use. Where as the Soldiers work just like the RF-602 but have better sync speed and groups.

usual triggers (im thinking PWs) plug into the flashgun/speedlight via a PC cord, right? judging from the pictures these lock onto the flashgun's hotshoe mount and thats all thats needed, right?

so for example, if i wanted to use my SB600 with some PWs, i would need to buy a hotshoe to PC adapter, but with these triggers i wouldnt, correct??

Hi guys, thanks for sharing!!
I have just bought The soldier for canon. I have two canon 550Ex flashes.
The trigger works superbly with one flash. Has anybody managed to make it work with the master triggered by the soldier and the slave as optical slave?
It seems that if you put the soldier receiver on the master and set the second flash as optical slave, the slave never flashes! Do you know if this is an incompatibility or it just can't work? With same configuration if I force the master with the pilot button, the slave is triggered! :(
A bit disappointed. Can anybody help?
Thanks a lot!!

Hi, Even if you got that chain to work (it certainly can with other triggers eg Yn RF-602s), I wouldn't recommend it. You lose a couple of clicks of sync speed! Much better to stretch to a second Rx unit. Cheers
