Canon Speedlite 470EX-AI overview | TechRadar

It doesn’t take lengthy to grasp that bouncing the output of a flashgun off a ceiling or wall can successfully building up the dimensions of the sunshine supply, subsequently making a softer, extra herbal taking a look lighting fixtures methodology. On the other hand, newcomers particularly may in finding it exhausting to play the angles, and to pass judgement on the most efficient diploma of soar to provide the optimal impact. Canon’s innovative new Speedlite boasts synthetic intelligence, which it harnesses to keep an eye on a motorized tilt and swivel head, thereby handing over an automated soar facility. 


  • Head bodily strikes round robotically beneath its personal continual
  • Absolutely automated and semi-automatic soar modes
  • Calculates the optimal soar perspective

Like maximum different mid-range flashguns, the Canon Speedlite 470EX-AI has a motorized zoom head that robotically tracks the focal period of the lens getting used. As with most up-to-date Canon flashguns, it may well additionally robotically discover whether or not the digicam you’re the use of is a full-frame or APS-C layout type, taking this into consideration when robotically adjusting the zoom atmosphere. However its primary declare to status is that it additionally has a motorized tilt and swivel serve as, so the pinnacle bodily strikes round robotically beneath its personal continual. It may possibly tilt upwards past the vertical, via a 120-degree arc, and swivel a complete 180 levels to each the left and the correct. 


Leap: zero to 120 levels

Swivel (left/proper): 180 / 180 levels

Zoom fluctuate: 24-105mm (auto) 

Flash publicity repayment: +/-3EV

Handbook continual settings: 1/1 to at least one/128

Dimensions (W x H x D):  75 x 130 x 105mm 

Weight (excl batts): 385g 

There are totally automated and semi-automatic soar modes on be offering, by way of a small transfer at the rear of the flashgun. In complete auto AI Leap mode, the Speedlite fires a pre-flash pulse on the matter, then tilts vertically upwards and fires a 2d pre-flash pulse on the ceiling. It then calculates the optimal soar perspective, in response to the gap to the topic and the gap to the ceiling. Should you change between portrait and panorama orientation, you’ll reposition the flash head by way of making use of a double light-press to the digicam’s shutter button. This depends upon orientation sensors constructed into the flashgun relatively than the digicam, so the entirety works correctly despite the fact that you’re the use of the flashgun off-camera. 

However what for those who’d relatively soar the flash off a white wall as an alternative? This can also be specifically helpful if the ceiling could be very prime or has, as an example, a herbal wooden relatively than painted white end. You could even favor to fireside your flash at a big reflector panel that you’ll place independently. That is the place the semi-automatic AI Leap mode comes into play. It allows you to manually level the flash head for your desired course after which press the ‘Perspective Set’ button at the facet of the pinnacle. This locks the placement into the flashguns reminiscence. Once more, you’ll transfer between portrait and panorama orientation and observe a double faucet of the shutter button to handle the similar soar perspective, the pinnacle tilting and swivelling as essential. In addition to totally automated and semi-automatic modes, the choice transfer has a zero-degrees choice for direct flash with out a soar or swivel.

Construct high quality and dealing with

  • Includes a conventional keep an eye on panel
  • Zoom serve as of the pinnacle moderately restricted 
  • Programmable stroboscopic flash mode lacking

Whilst the AI soar facility is leading edge, the 470EX-AI is somewhat typical in different ways. It has a standard keep an eye on panel in response to buttons, a rotary dial and mono LCD show. The feel and appear is somewhat dated, in comparison with some fresh Metz flashguns that experience touchscreens. The zoom serve as of the pinnacle is moderately restricted in comparison with in a similar fashion priced flashguns, rated at 24-105mm in full-frame phrases, relatively than the now extra standard 24-200mm. There’s additionally no pull-out reflector card within the head, which is most often featured on mid-range flashguns. Maximum in a similar fashion priced flashguns have a programmable stroboscopic flash mode, which once more is absent.

The 470EX-AI has a somewhat beneficiant most continual ranking of Gn 47

Extra unusually, the 470EX-AI lacks the RF (Radio Frequency) communication of Canon’s 430EX III-RT and 600EX-RT (each the unique and Mark II editions). For wi-fi off-camera flash, it may well subsequently simplest perform by way of an optical hyperlink, and simplest as a slave, now not a grasp. You subsequently can’t slot the flashgun into your digicam’s hotshoe and use it to wirelessly keep an eye on any other flashgun in slave mode. It additionally lacks the weather-seals of Canon’s significantly extra tough, top-flight skilled 600EX-RT II flashgun.

At the plus facet, the 470EX-AI has a somewhat beneficiant most continual ranking of Gn 47 (Information quantity at ISO 100/metres). Provided accessories come with a ramification dome, stand and padded cushy case, all of that are of fine high quality. 

The most recent tech steadily comes with backwards compatibility problems and this flashgun isn’t any exception. Absolutely automated AI Leap mode is unavailable when the use of cameras introduced sooner than the second one half of of 2014, together with the EOS Rebellion T5 / 1200D, EOS Rebellion SL1 / 100D, EOS Rebellion T5i / 700D, EOS 70D, EOS 6D, EOS 5D Mk III and EOS-1D X. When taking pictures with those in addition to the more moderen EOS Rebellion T6 / 1300D and mirrorless EOS M3, EOS M5 and EOS M6, you’ll simplest use AI soar in semi-automatic mode.  


  • TTL flash metering is most often correct and constant
  • Recycling after a flash is silent and lovely swift
  • Battery lifestyles is ready two-thirds that of the 430EX II-RT

As its Gn ranking would suggest, most output is a bit more tough than from the 430EX III-RT, however weaker than from the 600EX II-RT. TTL (Via The Lens) flash metering is most often correct and constant, each for direct flash and when the use of the flashgun in soar mode.    

Recycling after a flash is silent and lovely swift. In reality, recycling is nearly instant at continual settings of between 1/128 and 1/four. At half-power and full-power settings, recycling instances are 1.1 and a pair of.three seconds with NiMH batteries, or 1.three and four.2 with alkaline batteries. Battery lifestyles is ready two-thirds that of the 430EX II-RT, starting from round 115 to 800 pictures on a collection of 4 alkaline cells, relying on output continual and what sort of you employ the motorized soar/swivel and zoom purposes. Canon claims that, in observe, battery lifestyles is ready equivalent when the use of each flashguns in soar mode, because the 470EX-AI reduces the quantity of trial and mistake.


In many ways, the 470EX-AI is a actually leading edge flashgun. It’s specifically helpful for newcomers who’re frightened about methods to set the perspective of the pinnacle manually for efficient soar flash. On the other hand, pointing the flash at a wall or ceiling isn’t precisely a troublesome factor to do, and also you don’t most often want to set the perspective very exactly. It may possibly if truth be told be sooner to set the soar perspective manually, taking into consideration that the flashgun wishes to fireside a pre-flash pulse on the matter, then swivel against the ceiling and hearth a 2d pre-flash pulse, after which figure out its soar perspective, each and every time you undertake a brand new taking pictures place. 

Some other sticking level is the fee, particularly in areas the place the 470EX-AI prices greater than Canon’s range-topping, pro-grade 600EX-II RT. The latter is a lot more tough and complex, comprises complete RF wi-fi communication and has higher construct high quality along side weather-seals.    

In the end, as suave because the 470EX-AI is, newcomers who’re tempted by way of its AI soar facility may really feel somewhat abnormal spending significantly extra on a flashgun than they did on their entry-level Canon DSLR and gear lens aggregate.
