Canon Speedlite 320EX vs 430EX II

320EX vs 430EX II Speedlite The new Canon 320EX “hybrid” flash is the first camera flash with a built-in video light.

With the 320EX, Canon launches a 4th model of speedlite flashes. The closest relative to the new 320 EX is the current mid-range model Canon 430EX II, introduced in 2008 and priced at around $270.

The 320EX was announced in February 2011 at $249 and is similar in many respects: both flashes support the latest ETTL (II) technology, feature a flash head with swivel and tilt for indirect flash and a metal flash foot with quick release lever for easy attachment in the accessory shoe.

They also both offer Canon’s wireless TTL slave mode which is the easiest way to improve the quality of your lighting, with 3 groups and 4 channels to choose from. But there are also a number of significant differences.

Which flash should you buy – 430EX II or 320EX? Here are some facts, pro’s and con’s to help with a buying decision. Make sure to check the 320EX review and 430EX II review for in-depth information.

430EX II vs 320EX – Comparison Table

The 2 flashes aim at different target groups which is why they come with a slightly different set of features. Despite the lower price there are some exclusives found on the 320 EX only.

Biggest Advantages 320EX vs 430EX II

2 features make the 320EX unique: its built-in video light, and the camera remote control feature (which is also present on the other new Canon flash, the entry-level 270EX II).

Video Light

320EX video LED detailThe 320EX is the only Canon speedlite with a conventional flash tube plus an additional continuous LED lamp to support video shooting with Canon DSLR camera bodies.

Conventional flashguns are optimized to emit a large amount of light energy within a very short time frame – around 1/300 sec for a full power shot. But it takes around 3 seconds before the next flash can be fired, and that’s why they are completely useless for a video shoot.

While not a bright as a flash, it’s a huge advantage that LED’s are generating continuous light. Switch it on like a flash light, and the video lamp of the 320EX, using the same 4 AA cells as the flash tube, lights up your scene for up to 4 hours.

320EX vs 430EX II - LED switchWhen used with the Rebel T3 (EOS 1100D) or Rebel T3i (EOS 600D), the optional auto light mode even automatically activates the LED light depending on the ambient light to ensure a proper exposure for the video clip.

Admittedly, the LED on the 320EX is pretty weak with 75 Lux (some professional LED panels have 600 or even 900 Lux) and it is also a harsh light source producing dark shadows. But it’s better than nothing, and it helps extending the usability of your DSLR’s video mode well into darkness.

Check here the 320EX video LED in action in this test video from the Speedlights.net youtube channel:
 


 

Camera Remote Feature

The second innovation comes in form of a camera remote control mode, built into the flash.

320EX camera remote buttonThis features is activated with a button on the right side of the flash body, which I first thought was the wireless TTL sensor. However, that sensor is located on the front side of the flash body, the same sub-optimal solution as found on the 430EX (II).

The remote feature works in the same way as the Canon RC-6 infrared controller; it requires a DSLR that’s compatible with infrared wireless remote controllers; my Rebel T1i qualifies, and I can use it therefore. The range is up to 16 feet according to Canon specifications.

remote sensor on T1i for trigger with 320EXAs of March, 2011, that means this new speedlite feature works only with the following digital SLR models: EOS 5D Mark II, EOS 60D, 7D, EOS Rebel T3i, T2i, T1i, EOS Rebel XSi, EOS Rebel XTi, XT, and the original Digital Rebel (6 million pixel version).

The photo here shows the remote sensor of the Rebel T1i, embedded in the grip. Through this sensor window, the camera receives the trigger signal from the 320EX, and then takes a photo with a fixed 2-second delay.

Now, the big question is whether you need this feature or not. It seems more of a gimmick, actually, since it does the same as you can do with any accessory remote controller. There seems no advantage in using the flash for this task. But it’s neat – just like the Yongnuo RF-602 wireless flash trigger doubles up as a camera remote control.

Additional Benefits

Apart from the video light and the remote feature there are some other advantages compared to the 430EX II:

  • LED can be used as modeling light
    This could be actually a major benefit for some of us, but limited by the low range of the LED. Conventional flashes use high-frequency bursts of small flashes as modeling light, with a typical maximum duration of 1.0 to 1.2 seconds – a very short moment to evaluate the shadows on the subject and therefore a bad solution. The LED is a continuous light source and therefore not bound to these limits; you can let it shine until the batteries are depleted.
  • A little smaller and lighter
    There’s not much difference when you compare the dimensions of the 2 flashes on paper, but you’ll notice a clear difference when you see them side by side. The body of the 320EX is a bit more compact, but especially the flash head is much smaller vs the 430EX II. I think that a smaller speedilite is a better speedlite, and therefore see the advantage on the side of the 320 EX.
  • Slightly less expensive
    Canon’s official price for the 430EX II is $299, and the street price is around 10% lower. This leads to the prediction that you’ll have to pay around $249 – 10% = $225 for the 320EX. It is to be expected however that it will take a while until this slightly lower price level is reached, at the beginning you’ll pay the first mover price of $249 and that’s not much less than the 430EX II price.

Read the full Canon 320EX review to learn more about this flash. I was pretty critical first, but I must say that I started to like it; it’s a good partner for my Rebel T1i camera body with the kit lens.

Advantage 430EX II vs 320EX

For HD video the 430EX II is completely useless; there’s simply nothing it would be good for in that use case. But as a photo flash, the 430EX II has a number of very big arguments on his side.

320 EX review Back panel no LCD

Higher Guide Number

Canon uses always the guide number for maximum zoom in their communications. For the 320EX, it’s GN 32 (in meters) with the 50mm reflector position. The 430EX II has GN 43 at the 105mm setting. Now, how do these values compare?

On Speedlights.net the guide number is always used with 35mm reflector position. There, the 320EX has GN 24 (since you have to zoom to the wide reflector setting) while the 430EX II has a guide number of 31. As you can see this is a clear difference.

The table shows the guide number curves for full frame camera bodies like the 5D Mark II. At 24mm and 50mm, both flashes are pretty close. But in between, and from a 70mm lens setting on, the 320EX falls clearly behind.

320EX guide number full frame vs 430EX II

With EF-S camera bodies like the Rebel series DSLR the shape of the 2 curves stays similar, but the lens zoom positions have shifted. The 50mm reflector setting of the 320EX can be used with a 35mm EF-S lens already, and the 24mm reflector setting covers from 15mm focal length on.

320EX guide number EF-S vs 430EX II

The 430EX II is smart: it automatically detects the size of the camera’s image sensor and selects a more narrow reflector position on the speedlite without user intervention. Stronger by nature already, the 430EX Mark II gets even more extra juice with this trick.

It’s not that the 320EX is too weak for everyday shooting. Most digital EOS cameras automatically switch to ISO 400 when a flash is detected. This higher ISO setting doubles the flash guide number, which means you have 2 * GN 24 to work with.

But clearly, more is always better, and GN 24 won’t be always enough, e.g. for bounced flash with high or dark ceilings, or when used together with umbrellas, softboxes or other light modifiers. The 430EX II is a much better candidate for that.

Wide Angle Auto Zoom Reflector

On the 320EX there are exactly 2 zoom positions available: you can either leave it in the 24mm default setting, or pull out the front of the flash head to manually “zoom” to 50mm position. There is no wide-angle panel built in, and there’s also no diffuser (‘stofen’) for this flash (given the rounded front screen, a special design will be required).

With the integrated wide-panel in place the 430EX II covers as low as 14mm already for full frame, or from 9mm with EF-S. The auto zoom feature moves the flash head reflector with the lens in a range between 24mm and 105mm (15mm – 65mm with APS-C / EF-S).

Canon speedlite 430EX II with wide panel

The 320EX is enough to cover the standard Canon 18-55mm EF-S kit lens, but it’s not compatible with super wide angles like a 10-22mm, and it wastes power with telephoto lenses.

Real AF Assist

When it comes to AF assist there are big differences between the designs with significant impact on low light shooting. A good AF assist beam is unobtrusive, uses a pattern for contrast, and covers a wider range of AF sensors.

430EX II af assist beamThe Canon 430EX II uses the latest technology for low light focus assist. The dual beam is state of the art, with 2 bright red LED lights. The projection of a striped pattern allows precise focusing even in situations with zero contrast (such as a white wall). And the official range of 10 meters is very good.

In comparison, there’s a much simpler system found in the 320 EX. In normal photo mode, the flash uses as AF assist what Canon calls “intermittent flash firing system” and people on the discussion boards call the “disco light”: a sequence of small flashes from the flash tube itself. Not only is the maximum range shorter with 4 meters max.

Using the flash tube can’t really be called unobtrusive, it’s actually pretty annoying for your subject.

The 320′s LED lamp would be an alternative but it is usable as AF assist only in live view mode; Its usefulness is also limited by the fact that there’s no pattern projected which is why it can increase an existing contrast, but it can’t generate contrast e.g. on a white wall with no structure itself.

Real Manual Flash Mode

430EX II manual mode for wireless flashFor wireless flash with radio triggers, “strobist” shootings etc, you want a speedlite with a real manual mode, where power levels can be set on the unit itself.

This mode is not present on the 320EX. It has a manual mode, but only controlled through a compatible camera body. As soon as you’re shooting outside of the wireless Canon TTL world, the manual mode option is gone for good!

On top of that, it’s also often more convenient to set an output level on the flash, and not have to dig through the camera menu. The photo shows the LCD screen of the 430EX II flash with manual power set to 1/2 with a -.07 adjustment.

Other Advantages

There are a couple more factors speaking for the established mid-range flash, apart from the main ones mentioned above.

  • LCD display
    Only the 320EX lacks the LCD display; I don’t think this is a big deal since there’s not too much to set on the flash unit itself, and there a lots of examples of flashes that are easy to use without LCD (e.g. the Nissin Di-622 Mark II)
  • Exposure compensation on the unit
    In case a flash exposure compensation is needed, your only option with the 320EX is to set one on the camera. The 430EX in contrast allows dialing in a flash exposure compensation on the speedlite itself.
  • Analog TTL mode
    Canon 320EX is only compatible with digital type “A” camera bodies. The 430EX II can also be used with film based EOS camera bodies, and with PowerShot G series cameras (type “A” and “B” cameras)
  • Stroboscopic mode in wireless setup
    The 430EX II can be used in multi flash mode as part of a wireless setup, but not in the camera hot shoe. The 320EX doesn’t offer that feature at all.
  • More custom features
    There are a couple more custom features available with the 430EX II, e.g. switching display units from meters to feet, which don’t apply to the 320EX. The list below doesn’t contain anything game changing however, it’s simply that more features come with more customization

Recommendation

If you’re never shooting video with your DSLR the decision is easy: get a 430EX II, not the 320. If you’re shooting a lot of demanding flash setups, and shooting more ambitious video projects, the call is also simple: buy a photo flash and an extra video light, e.g. a real light panel, or a ‘hot’ light.

What’s the 320EX good for, then? I think it’s a good compromise when you like to experiment with your camera’s photo and video modes, and you have no plans to move beyond using the kit lens: the simple video light is a lot better than no light; and the flash, especially when combined with higher ISO, should be sufficient for most of your shooting.

Other Alternatives in the $200 – $300 Range

There are 2 other options worth considering in the price range of the 320EX, both from third parties.

The first is the Nissin Di-622 Mark II, which you can get for less than $200. It’s simple but very powerful, has a real manual mode, a ‘real’ AF assist (single LED), auto zoom, wide panel, and even some features not found on the 430EX II, e.g. 2 optical slave modes, or a built-in reflector card. Go here for a full in-depth Nissin 622 Mark II review.

The second, with around $230 pretty exactly in the same price range as the 320EX, is the 50 AF-1 flash from Metz. This flash features pretty much everything the 430EX II has to offer at a slightly lower price point, and with a slightly simpler user interface. The 50 AF-1 is the evolution from the precursor 48 AF-1: learn more in the 48 AF-1 review.

Finally, there are more options in the Canon world: The current top-grade speedlite is the Canon 580EX II. The 270EX and new 270EX II are the entry-level flashes from Canon: they don’t bring a lot of features to the table, but at least they are small, light and relatively cheap (at last for a Canon flash).

If you don’t mind buying a used flash then also have a look at the Canon 430EX (around $200) or the 580EX (around $350).

  1. Phil Steele says:

    Terrific comparison! Thanks so much for posting this, you really made the differences between the two models clear.

  2. Benjamin Green says:

    Hi Fransener,

    Really appreciate this blog, and your response to my previous comment RE: Autoflash on 580EXII.

    And this 430EXII vs. 320EX comparison is (like the blog) very good and quite interesting overall.

    However, I think your statement:

    “…GN 24 won’t be always enough, e.g. for bounced flash with high or dark ceilings, or when used together with umbrellas, softboxes or other light modifiers. The 430EX II is a much better candidate for that.”

    …is an incorrect analysis of the information presented in the Zoom/GN graphs.

    In fact, I believe the inverse is true.

    I think you may have mislead yourself by being a bit too rigid in comparing strictly the 35mm zoom setting guide numbers. While admirably consistent with your site-wide standard of measurement, in this case it distorts the relative differences between the two flashes being compared, since the 320EX does not have a proper 35mm zoom setting while the 430EXII does.

    When you look at the graph points corresponding to the zoom settings the two flashes do have in common (24mm and 50mm) the graph shows that the flashtubes themselves in each unit are actually very close in max light output (the 320EX is merely about 1/3 of a stop less bright.)

    Since the zoom reflector in a flash is most effective at increasing efficiency of illumination when there is nothing between the flash head and the subject (e.g., when using the flash with no modifier), this is where the 430EXII pulls well ahead of the 320EX.

    So, a sports shooter or wildlife shooter using only straight-ahead, on-camera flash at max zoom setting in conjunction with a long lens would have a compelling reason to prefer the 430EXII.

    Or a “Strobist” who tends to favor bare flashes over “softening” modifiers like umbrellas would also see an advantage in choosing the 430EXII.

    (This holds true for “non-softening” modifiers like snoots and grids, which can take good advantage of a zoom reflector’s increased efficiency, too.)

    OTOH, when a flash is used with an umbrella, softbox, or similar “softening” modifier, or used for bounce flash, the effect of the zoom reflector setting on the output of the flash+modifier combo is far less than it’s effect on a bare/snooted/gridded flash (and in general, photographers will favor the wider flash zoom settings common to both flashes when using them with softboxes/umbrellas, to get the most even illumination of the modifier.)

    The very similar levels of max light output of the flashtubes of the 430EXII vs. the 320EX mean that they can be expected to perform very similarly in softening modifiers, with the 430EXII having just a slight advantage, being slightly brighter.

    That said, there are a couple of other (IMHO minor) advantages that the 430EXII’s greater zoom range does confer. Some photographers may choose to make creative use of the 430EXII’s ability to produce a pronounced hotspot in a softbox or umbrella. And in a bounce flash situation, the 430EXII’s greater zoom range increases the ability to control the flash exposure’s contrast ratio.

    Hope this helps. Keep up the great work!

    • fransener says:

      Hi Benjamin – I was out for some time therefore slow at responding; but you’re making a valid point here: in an umbrella you want to use the flash at the wide angle setting typically, and as can be seen from the data tables the output is very close at 24mm, so not a real advantage for the 430EX II. Similar argument holds true for bounced flash if 50mm is used (a focal length which is often recommended for that use case, and even implemented in Metz and Canon flash firmware). Frank

      • Benjamin Green says:

        Hi Frank,

        Good to see you back in action, and thanks for your reply. (And my apologies if it seems like I just chime in here to correct you–I–and I hope other readers–appreciate that it is of course easier to pick out the odd mistake here or there when reading the completed article than it is to catch it in the midst of writing the whole thing from scratch!)

        A couple of further points RE:430ex vs. 320ex:

        For off camera flash, IMHO the 430 is the obvious choice, since it has the on-board manual power adjustment necessary to work well with simple radio triggers, and has the legacy TTL functionality needed to work properly with RadioPopper RP cubes for remote manual adjustment.

        The 320EX, lacking on-board manual power adjustment and lacking legacy TTL (very disappointing!), is limited to using the Canon Wireless system for OCF, which works great when conditions are right for line-of-sight signal transmission, but not so great in adverse conditions like outdoors in the daylight or at great distances. (On second thought, I suppose you can also use the 320 with the Radio Popper PX system, but if you can afford those triggers you probably can afford the difference in price between the 430 and 320 anyway.)

        IMHO the 320EX is best used on-camera, since it can be used as a Canon Wireless master flash (at least on recent Canon bodies) with nearly the same power as the 430EX, but at significantly lighter weight, which of course is always helpful with an on-camera flash.

        Looking forward to the Yongnuo ST-E2 review. I am particularly interested to know how well the AF assist works on that unit.

        Best,

        –Benjamin Green

        • Speedlights says:

          Hi Benjamin – no worries and thanks for the further details on RadioPopper RP which I’m not familiar with – but I think other people here will appreciate the info a lot!

          The 320EX is a good choice for hobbyists shopping for their 1st (and only) flash who don’t have plans to do “strobist” stuff or work in a multi-light setup. I think it’s a good wireless light source for hand held use – at close distance, no big light modifiers or other fancy stuff. For everyone else the 430 is better – or maybe even a couple of LP 160′s / YN-560 flashes.

          What will not work is using the 320EX as a master, even on 60D, 600D or 7D bodies. It’s their internal flash that works as a commander, but not an external flash unless the professional line. This is how it works in the Nikon world (that I admittedly know better than Canon, although I have both systems now). Hope this does make sense, and let me know if I should be wrong (can’t test it with the T1i). Frank

          • Benjamin Green says:

            Hi Frank,

            Thanks for your reply. When I posted the comment the other day, I had looked through the 320EX and 7D manuals and thought I had confirmed that the 320 could act as a master on the 7D, but when I checked the manuals again just now I realize that actually the documentation is not quite clear one way or the other.

            Given that the 7D body has the Master capability on board already, it seems logical that it should be able to use whatever flash is connected to transmit the signals, but yes of course the only way to know is to test.

            I do not currently have a 320EX or a new enough Canon body to test myself, but I would be interested to hear from someone who does…

            If it turns out that the 320 cannot be a master on a 7D/60D/600D, I wonder if that could possibly be changed in future via a firmware update.

            On a different note–do you have an idea when the Yongnuo STE2 review will be posted?

            Regards,

            –Benjamin Green
