Sigma ef-500 dg st won't work with my d300 or 200 in ttl mode

This Sigma flash is not Ittl compatible. The D300 and D200 Nikon must have Ittl compatible flash to operate in any of the Automatic modes. It is a great flash but will not work on those two cameras.

Hello there. It seems that the Sigma EF-500

John, there is a difference in sync times between film and digital flash. It's taken the third party manufactures a little time to catch up so there is a lot of "film" flash units out there. I'm understanding that the Sigma flash doesn't fire at all which is pretty amazing I would have thought it would fire just not at the correct time. This flash isn't a total loss because it can be used wireless with a slave unit for fill or even a main light triggered from a mini transmitter on the camera hot shoe. Here is a link to an e-Bay auction to see what I'm saying.

I use this type of system for a location shoot, there are no wires and I can set up and balance my lighting to each set with no more dark backgrounds hope this was a help

Can I use a sigma flash EF 500 with Sony Alpha 350

Yes, if it has a Minolta/Sony mount. The Sigma EF 500 has been producedin different mount, so that the model can fit different cameras from different producers. A Sigma flash for Sony should have SO-ADI written on it.

Manual for Sigma EF-500 DG Super

You can download the manual from
Just answer a few quick questions about its performance, value for money etc and the link to download the manual opens up. Just be careful, because there is also a manual for the Nikon version of the same flash and they are a little different.

Hope this helps.

A: For Sigma issue:

The Sigma EF-500 flashes have very small chromed contacts for the batteries. Even though they may not look corroded, they may not power up or conduct enough power to fully cycle up. Use a polishing tip in a dremel or an ink eraser tip to clean the internal wire contacts and the flat contacts on the door. I use dielectric grease on a q-tip to apply a coat to all contacts and cleaned battery terminals to minimise future issues.

Broken shoe mount on Sigma ef-400 dg super Flash

Contact Holly Enterprises- The manufacture a metal foot to replace broken plastic ones on flash units. The made one specifically for some of the popular Vivatar flash units and I am not sure if theses can be used with your flash unit ro if the have others that are made especially for you strobe. I also don't know if the are user installable.

If you have to take the unit apart to do this procedure, you have to consider the high voltages that can remain in the unit even after is it turned off, If Holly can not assist you, check with the distributor of the flash- It may be better to have it professionally repaired in case there are other issues such as disconnected or broken wires that may have been damaged when the base was torn off.

Please let me know if you have any lick with this. Ed

Sigma Flash EF-500 DG SUPER

I use one of my cams with a sigma 500 DG-ST in a nightclub

ive done 3 of the hot shoe connectors in the last year

look up sigma's website and find the contact info
give them a call and they should after some arguing ship you out the parts

every time i have ordered parts they try and get me to send it in for repair even though by the time i am ordering the parts the flashgun is already in bits & i tell them this they keep telling me how dificult it is to do...

for the canon fittment do the following

at the base of the flash remove the 4 screws
this removes the bottom section
unclip the wireing harness
there are 2 screws securing a small metal plate remove them

now there are 4 screws securing the small PCB, remove them, you can now take out the boot from the bottom be careful as the pins and the springs will want to come out
pay atention to the locking pin and how its orientated

swap over the broken boot with the replacement then retrace your steps to get it back together
