Sigma Electronic Flash EF 500 DG Super

Review Date: Dec 8, 2007 Recommend? | Price paid: $259.00

Pros: Optical Slave Mode, Cheap, Good Power
Build quality very suspect. Inconsistant Ettl flash output.

Although this is a great peice of equipment for when you first start out, it is not up to standard for heavy professional use.

I have two DG 500 Supers and I love using them as optical slaves in manual mode when I have the time to muck around... but... it is not up to standard for professional use especially demanding jobs such as weddings.

If you are looking for a flash unit that you can use for professional work as you grow then really save the etra pennies and get a EX 580. Build quality is far superior, wireless and ettl wlash is far more consistant and the EX 580's recycle so much faster. The 580's also have the conection pin to add external battery packs if you wish to upgrade later.

On the positive, I do find the optical slave worth while. You can see the result here wher I shot a DG 500 into a silver umbrella.

Sigma Electronic Flash EF 500 DG Super

Review Date: Dec 7, 2007 Recommend? no | Price paid: Not Indicated | Rating: 5 

Pros: If you want consistant exposures, set the out put manually and run it in TTL or as a slave flash.
Build quality is no where near as good as a Canon EX Flash and flash exposures are inconsistant

I have two Sigma DG 500's and both after a period of time are failing miserably with error readings and inconsistant flash output.

The Canon EX 580 which I purchased recently is far superior. I wish I had of just bought another EX 580 instead of trying to save a little extra cash with the DG 500's.

Trust me when I say these flashes are ok if you are doing hobby work but they are far to inconsitant and slow for professional work such as weddings etc.

Recycle times are far slower than my EX 580 and I find that the DG 500's do not expose as well as the 580 in harsh direct sunlight (Always underexposing even when I keep giving +1 or more flash exposure compensation).

If you have the time to set up your flash exposure manually and want to use them this way as a slave... well no problems...


This was taken with a DG 500 off camera slave flash set with manual flash output bounced into an umbrella.

As you can see produced a nice portrait. but if you think you are saving money by purchasing one for shooting demanding jobs then forget about it.
