What’s a Flash Gun?
A camera flash is an external unit which attaches to your camera via the hot shoe. It’s a lot more powerful than a built-in flash. And it will allow you to take better quality photos.
The following are just some of the advantages a flash gun has over a built-in flash.
- Off-camera flash – A camera flash can be used off-camera by using either infra-red, radio or a change in light as its trigger. The ability to do this will give you much more creative potential.
- More power – While not as powerful as studio lights, a flash unit still packs a serious punch. If you use multiple units you’ll be able to build a mobile studio.
- Direction of light – Built-in camera flash aims in one direction. A flash unit can be manipulated to aim the light in different directions. This will allow you to bounce the light off the wall or a ceiling when indoors.
- Light modifiers – There are lots of light modifiers you can use with a flash. Soft boxes, snoots, or shoot thru umbrellas are some examples of these.
- Stroboscopic effect – Turn the strobe into the shutter in a darkened room. Keep your camera shutter open, and use a burst of flashes to create a multi-exposure look with a moving object.
Canon Flash Guns
Canon makes a series of flash guns, often referred to as strobes. These units are exclusively for Canon cameras and could damage other camera bodies.
They have an infra-red system to communicate with each other, enabling multiple units to be triggered at the same time.
Canon’s best and most expensive camera flash is the 600EX II-RT. It’s a formidable unit, with a flash power that’s not surpassed by any other flashes in this article.
The following are some of the key advantages of this flash. The only real drawback is the expensive price tag, not surprising for Canon’s leading strobe though.
- Rotating head – Can rotate in all directions, enabling you to bounce the flash off the ceiling or a wall.
- Stroboscopic – Allows for a burst of flashes in very quick succession.
- Wireless – Through the use of either a radio trigger or infrared you can trigger this unit, in addition to other units that are synced with it.
- Manual power – It’s possible to reduce the power from 1:1 down to 1:128 power, useful for saving battery life and controlling the light.
- Focal length – You can concentrate the flash on a point by zooming in from 20mm to 200mm. There is also a diffuser that allows you to spread the light out to 14mm.
- Battery life – In an improvement from the previous model this model uses 50% less power for the same performance.
This strobe has artificial intelligence built in, which is used to judge the optimum bounce angle to light your subject.
Prior to taking the photo, the strobe will flash twice. Once at the ceiling and once at the subject. From these two flashes it will work out the optimum bounce angle for your flash.
There is also the option of going semi-automatic with this AI, so you can bounce off a side wall or a reflector dish. The positive aspect of this feature doesn’t compensate for what you’ll lose in other features though.
This flash is not usable as the master flash, and can only be used as a slave. The AI is also only available on Canon cameras built after 2014 as well.
- Rotating head – This goes from 0 to 90 degrees looking up and down, while side to side it rotates 180 and 150 degrees.
- Focal length – 24-105mm with a 14mm diffuser.
- Manual power – From 1/1 to 1/128th power.
- Wireless – One of the key downsides here is that this lacks the RF trigger, but it does use IR.
The 430EX III is an excellent purchase for those on more of a budget, but who want a Canon speedlite. This unit has a very respectable flash strength, more than enough for the majority of situations.
- Rotating head – You can adjust this from 0 to 90 degrees looking up and down, and it rotates side to side 180 and 150 degrees.
- Focal length – 24-105m with a 14mm diffuser.
- Manual power – from 1/1 to 1/128th power.
- Wireless – This flash supports both RF and IR triggers. You can’t use it as a master though, it can only be used as a slave.
Nikon Flash Guns
Nikon has its own range of strobes as well, and like with Canon these are brand specific. Don’t try mounting these on non-Nikon cameras, unless you feel the urge for a new camera.
The following are a couple of strobes you can buy for your Nikon dSLR.
This is currently Nikon’s best strobe, and it’s a great piece of equipment. It has great performance when set to TTL. It also runs cooler than other flashes, allowing you to take 100 simultaneous photos even with the flash set to full strength.
This unit will work as your master flash in conjunction with other flash units, and to do this you can use either IR or RF. Where this diverges from the Canon though is that for RF it only has a receiver fitted. This means you’ll need extra equipment to trigger this unit when using RF.
The following are the other features that come with this flash.
- Rotating head – Allows you to angle the flash from -7 to 90 degrees to bounce the flash, and 180/180 left to right.
- Focal length – A range of 24-200mm and a 14mm diffuser.
- Manual power – This goes from 1/1 down to 1/256th.
- Wireless – Works as a master and slave with IR and RF.
The Nikon SB-700 is very much in the same bracket as the Canon 430EX III. This strobe is the superior unit though, with a range of features not provided with the Canon device. The key one with this regard is the fact this strobe will act as a master, making the need to shell out on the more expensive SB-5000 less.
You’ll also have the advantage of greater maneuverability of the flash head itself. The only real downside is the lack of RF, which can be mitigated by buying additional external RF triggers.
A range of other equipment comes with this as well such as gels and a diffusion dome.
- Rotating head – Aim up and down at -7 to 90 degrees. Swivel right and left at 180/180.
- Focal length – Runs from 24-120mm, with a diffuser that gives 12mm.
- Manual power – 1/1 down to 1/128th.
- Wireless – Works as a master and slave, but only with IR.
Sony Flash Guns
Sony also produces a flash which is specific for their cameras. Using this in conjunction with your dSLR or mirrorless is a great idea. The flash is designed to make the most of Sony’s operating system and design.
You’ll be able to use this on the entire Sony camera line. Depending on the model you’ll have to use a specific adapter. This is great for Sony users who can go from the more budget-friendly cameras all the way up to the alpha line.
While it’s true there are other brighter flashes, this is more than made up for in the way it’s designed to fit with Sony’s cameras. The flash, for example, is designed to exactly match the camera’s high-speed flash sync.
The camera comes with IR wireless control, it’s fully water and dust resistant. And it has a simple display screen on the back from where you can adjust the flash to your needs.
- Rotating head – This goes up to 90 degrees, and down to -8 degrees. It will rotate left to right through 270 degrees.
- Wireless – It has built-in infra-red controls.
Other Flash Guns
There are plenty of other flashes on the market as well, these are often aimed at multiple camera bodies. You will still need to look for a flash that has been built for your camera body.
Some will work for almost everything, for example, the Yongnuo YN560IV.
This is a very affordable flash unit that’s designed to work on any model. At $40 you really can’t get much cheaper for photographic equipment, yet you get a lot for your money as well.
You can change the strength of the flash by eight different levels from high to low, though this is a lot less control than other units typically offer.
The rotating head offers good flexibility through a fairly standard 7 to 90 degrees up and down and 0 to 180 left to right. You’ll also need to work out the control settings yourself, as the English translation on the instructions isn’t very good.
The really cheap price and simple controls make this a great choice if you’re new to flash.
The Yongnuo YN560 IV is another flash you can use with camera bodies from different manufacturers, a factor that can be useful. The price is also right at around $70 per unit, which puts this flash in the budget category. So what are you getting for your money then?
The good is that this is a unit with a wireless trigger that can work both as a master and a slave. You can once again manually change the power of the flash, but automatic TTL is a feature that’s not included.
The recycle speed between flash bursts is good. This is a nice flash for those learning to use off-camera lighting for the first time.
A step up from the Yongnuo and the Neewar is the Hahnel modus 600RT. This is a great unit that is cheaper than its Canon and Nikon counterparts, but offers just as much if not more in features.
The first thing that really stands out is that this flash uses a lithium-ion battery, as opposed to the double A batteries other strobes tend to use. This gives you a lot more power before this battery runs out, though if you need additional batteries their not cheap.
The flash can be used in a stroboscopic way, and you’re able to direct the flash up and down -7 to 90 degrees, and side to side 180/180.
The flashgun also comes with both IR and RF triggering as both a master and a slave. Hahnel offers deals to buy two units, giving you much more lighting flexibility.
The Metz Mecablitz 64 AF-1 is a top of the line flashgun, with an expensive price tag to go with it. Is it worth the money then? The answer is yes, and you’ll have a great pro level strobe.
Designed to be compatible with the heavy hitters like Canon, Nikon, Sony, and the micro 4/3rds market. It packs a GN 64m power rating with a range from 24-200mm, and a 14mm diffuser.
It’s got a good swivel head that goes through 180/180 and -9 to 90 degrees vertical swing. A nice extra bonus not seen on other flashes is that there is a small fill flash that can be used when you bounce the main flash off in a different direction.
To change the settings there is a nice intuitive touch screen panel on the back of the flash. As you’d expect from the price tag this works as both a slave and master, however only in IR.
A good flashgun is really important for your photography, especially if you’re a portrait or product photographer. This guide will have given you a range of options, with the brand specific flashes difficult to look past.
Canon makes a very nice 600EX II/430EX III combination, and Nikon a good SB-5000/SB-700 partnership.
Those looking for something else though should look at the Hahnel Modus 600RT, this is a great flash that’s more than a match for the brand specific options.
Should you wish to wait before dropping more money, the Neewar or Yongnuo are probably the way to go.
