About Canon

A powerful flash with a maximum guide number of 58/191 at ISO 100 in meters/feet (at 105mm focal length), This Speedlite replaces the 550EX and features faster recycling, more consistent color and enhanced controls

The Speedlite 580EX flash is compatible with Canon's E-TTL II (Evaluative Through The Lens) auto exposure technology. When combined with a compatible Canon camera, E-TTL II utilizes subject distance and other information that automatically modifies flash power, resulting in accurate flash exposure regardless of subject size, reflectance, or photographic composition.

The Speedlite 580EX flash is compatible with all film and digital EOS cameras as well as G-series and Pro-1 PowerShot digital cameras. The flash includes two features especially for digital photography. EOS 20D and EOS-1D Mark II** digital SLR users will especially appreciate the Speedlite 580EX flash's ability to auto-compensate for the size of the CMOS sensor, and zoom the flash head automatically to match the effective focal length conversion. This feature allows the Speedlite 580EX flash to maximize the efficiency of its light distribution and produce more flashes from a set of batteries. When used with the EOS 20D or 1D Mark II** digital SLR cameras, the flash and camera communicate to make fine adjustments to auto white balance by electronically monitoring the charge level of the batteries and the duration of each flash burst, resulting in consistently accurate color for every shot.

Smaller, lighter, faster and more powerful than its predecessor, the Speedlite 550EX flash, Canon has further enhanced the new modelby reducing the full-power recycling time by about 25 percent, while increasing the maximum Guide Number power rating by about 50 percent.

The new flash unit provides photographers with intuitive controls. Mimicking the style found on Canon's line of popular EOS Digital SLRs, the 580EX model's new control dial, SET button and a high-speed sync / shutter curtain synchronization button put all major functions at the fingertips of the photographer.

The Speedlite 580EX Flash features an AF-assist beam, which is now better matched to the different focusing point arrangements of various EOS SLRs, compared to earlier models. The unit includes a swiveling flash head that turns a full 180 degrees in both directions, while a single release lock controls tiltand swivel adjustments. A wide-angle diffuser found on the Speedlite 580EX flashcovers focal lengths as short as 14mm. The flash also features a new catchlight reflector for optimal lighting quality during bounce-flash photography. The Speedlite 580EX flash features a total of 14 Custom Functions that provide maximum control over various flash functions such as recycling with external power and auto-zooming to match sensor size.

Wish I had 2 of these

Best flash I own, so many possibilites with it!!if you don't have one you should.My only complaint is the plastic shoe, it breaks if the camera is dropped, oops that has happened to me twice, I guess it is a plus to replace a $15.00 part as opposed to something more expensive, but still a hassle when it breaks, I have seen Nikons are made out of metal. wouldn't buy a Nikon, I'm just sayin'

Used Speedlite - perfect


from Newton, MA  -  Semi-pro Photographer

I use the speedlite with two other speedlites remotely fired in my studio. this used one looks like my older one. Cannot tell them apart.




from Jefferson, TX  -  Pro Photographer

I would have been satisfied with the rating of E that described this flash, but when I received it the condition was "Like New" not a blemish in sight. I couldn't be more satisfied.


flash purchase

Comparable to brand new. Good value.


Solid Work Horse


from SF Bay Area  -  Pro Photographer

I am a wedding photographer and I employ different styles of lighting but there are times that I must have a flash on top of my camera to make sure I get shots that I need. This flash does the job. I have two of these already but I am using them all the time and wanted to have another back up. I like this older model because it is strong and easy to use. Plus I can get a third party foot adaptor for it and easily add a 3.5mm cable port on it so I can use that to run to my off camera strobe trigger. These fill the need I have and are much cheaper than buy the newest Canon flash.


Great purchase for me!


from Temple City. CA  -  Photo Enthusiast

The 580 EX compliments my other 580 EX which I use along with two 540EX's on wireless triggers. Thanks adorama for all my gear.


Great product

Using this in High Speed Photography


Simpley awesome, love Canon/


from Temple City, CA  -  Photo Enthusiast

The Canon 580EX flash is my primary work horse, and its lived up to its reputation. I need to purchase two more in the near future. It compliments two 540 EX flashes that are mounted on two photo senors and work terriffic in manual mode. All my work is via manual flash photograpghy. I finally used the 580EX in program mode on my Canon EOS 1D MK 111 and perform flawlessly.


I would recommend this product to anyone


from Aurora, CO  -  Semi-pro Photographer

This flash has been great. It's really helped to use as fill or just use for snap shots.


Great flash


from Chicago, IL  -  Semi-pro Photographer

Great flash, but has a couple of shortcomings that the new version corrects. If you don't need a pc sync port or weather resistance, then the 580EX is a more affordable alternative to the 580EX II.
