Canon 430EX III-RT overview

  • 1Description

Canon radio flash capabilities are trickling down from their flagship model with the integration of a 2.4 GHz wireless triggering system with master and slave capabilities in the mid-range Speedlite 430EX III-RT. Much like its predecessor, the E-TTL / E-TTL II unit has a guide number of 141' at ISO 100 and 105mm along with a zoom range of 24-105mm and a wide panel that extends coverage down to 14mm. Bounce has been expanded with the ability to rotate 150° right and 180° left as well as tilt upwards 90°. Enhancing operation are a dot-matrix LCD and a Multi Dial for smooth maneuvering of the menu settings.

In addition to the newly implemented radio system for wireless flash, optical slave transmission is still available for greater functionality. The 430EX III-RT's electronics have been sped up with a faster recycle time of 0.1 to 3.5 seconds along with a Quick mode that shortens this to just 2.5 seconds. Also, it offers enhanced Flash Exposure Compensation and Light Distribution settings for making very specific adjustments to the output settings.

Versatility is still key with this compact unit, offering high-speed, 1st and 2nd curtain sync modes along with a variety of custom functions for setting the Speedlite up exactly as you need. A color filter and bounce adapter are included as well for adjusting the color temperature and brightness of the flash for more balanced lighting. And, it runs on 4 AA batteries.

Effective flash range of 2.3 to 77.4'
Exposure compensation of ±3 EV in 1/3 or 1/2 step increments
Light Distribution settings allow for Standard, Guide Number Priority, and Even Coverage settings
Radio master and slave functionality allows for the use of up to 15 flashes set up in 15 channels and 5 groups up to 98.4' away
Using optical transmission it can be set as a slave with an unlimited number of flashes within 4 channels and 3 groups
10 custom Functions and 8 personal Functions are available for dialing in specific settings
LCD panel on rear for viewing and changing settings
AF assist beam with range of up to 13.1'
Fresh batteries will provide approximately 180 full-power flashes

    Canon 430EX III-RT reviews

    Speedlite 430EX III-RT is rated 4.6 out of 5 by 176.
    Rated 1 out of 5 by from Fatally Flawed... This flash has one fatal flaw: the IR AF assist beam only covers (and only works with) the center AF point. Its predecessor, the 430 EX II, while not covering all AF points of the pro camera AF systems, at least supported the great majority. This guy does not even try if any AF point other than the center is selected, and the little horizontal beam it emits is rather pitiful. No idea what Canon may have been thinking here. Therefore, it is no alternative to carrying the heavy 600EX-RT in the hotshoe if you need IR AF assist, light, and ability to control OCF in the RT system. For a stand-alone hotshoe flash, the 430 EX II remains the best choice, IMO.

    Rated 5 out of 5 by from Yes on the 430EX III RT ! For 99% of us, this is the flash you need. It can act as a master and radio trigger other 430ex rt's or 600's. Actually, the decision for some might be do you get the RT trigger from Canon or do you get another 430EX III RT? It puts out enough light for most situations. It's a smaller footprint than the 600 and much lighter. And it's Canon, so it is built with reliability and quality. As for me, I am a one flash guy.. as a pro photographer said, If you think you need one flash use one flash. If you think you need two flashes, use one flash. If you think you need three flashes, use one flash. Oh, by the way, it's much cheaper than the 600, too. MUCH cheaper.

    Rated 3 out of 5 by from Great wireless set of features but overheating often Good solid flash. I upgraded from 2 Canon 430 EX II with triggers to 3 Canon 430 EX III RT. The built in wireless is great but Canon seems to have put a new overheat protection in these flashes and after about 20 shots they go into overheat protection and start firing only every 3rd picture. Very annoying and it can make you loose a lot of shots if you shoot in fast pace. The old Canon 430 EX II kept up with professional use very well but for the new Canon 430 EX III RT it seems they have chosen to target only enthusiast and make the professionals go for the twice as pricey 600 EX RT. Nice move by Canon but there are a lot of third party options. So if you are a professional I would not recommend this flash.

    Rated 5 out of 5 by from Awesome flash!!! I love this flash! The size has been reduced making a smaller footprint in my bag and the menu on the back of the flash is a BIG improvement over the version 2. I like the interactive display because it makes navigating a lot easier. The fact that it doesn't zoom to 200mm or there's no external power option is no big deal to me. You can't have it both ways if you want all the features in the world in a relatively small package. That's what the 600EX-RT is for! Nice job on this one Canon!

    Rated 5 out of 5 by from Beautiful Design, Great Flash! This flash is so beautifully designed and compact. It doesn't have as much power as the 600EX-RT, but it's much easier to carry. Be aware of two default settings that you may want to change. First, the red autofocus assist light is set to Off by default. Having it on makes autofocus much easier indoors, so you'll probably want to set it to on. To do this, set Personal Function 5 to 1, which sets it to On. Secondly, the modeling light is set to On by default. I don't use the modeling light and find its strobing effect to be very annoying. To turn it off, set Custom Function 2 to setting 3.

    Rated 5 out of 5 by from The most user-friendly Speedlite yet!!! I recently sold my 430ex to a friend, and bought two 430ex III RT's. The user interface on this new Speedlite is fantastic, and very intuitive to navigate/change settings. The 430RT's smaller size (as compared to the 600) makes it a convenient Master atop the camera, whether that flash is enabled, or merely being used to control another 430RT that's being used as an off-camera Slave. Can't wait to see this type of user-interface to make it onto future Speedlites.

    Rated 5 out of 5 by from Fantastic companion to the 600ex rt! I wanted to get a second speedlite for the occasional off camera flash set ups and I was hesitant about purchasing a 2nd 600exrt. I love my 600 but since I don't often need more extensive lighting set ups I didn't want to spend the extra cost. The 430ex iii-rt has been PERFECT for my needs. I am able to sync it with my 6d, st-e3-rt transmitter, my 600 and BAM! I now get to create amazing lighting set ups at a fraction of the cost of the 600!! Plus since it's lighter than the 600 it's a great go-to flash when I need it for more casual photography. I brought it with me on Thanksgiving and the output was fantastic. I am so happy with this purchase!!

    Rated 5 out of 5 by from First flash I did about 2 hours of research before purchase.� �Background: I am a beginner and hesitated as I was still picking up aperture, iso, shutter speed.� After I had a better understanding I decided it was time to pick up a flash.� I always just bumped up the iso in low light conditions, but depending on the camera, the grain and quality degrades.� Well the flash helps and I'm back to 200 shutter speed and low ISO in low light conditions without the degradation.� This appears to be a great beginner flash and glad I choose this model vs any higher end as I would have no use, yet, for the additional features.
