Had a slight accident with the camera and flash.
My flash unit snapped off the camera, and now the hotshoe connecters are damaged. Where can I get a replacement hotshoe for this flash gun?

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

You may download a copy of the manual from here. It's for the Pentax version of the flash, but I don't see anything in it that's Pentax-specific except for the mention that's it's Pentax-specific.

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.

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.

Sigma EF-500-DG, does not charge and does not become ready


Thank you for using FixYa for your problem

Always check the batteries first - make sure they have full charge (in the wrong way can discharge them) but if is it still giving the same fault, your flash is faulty.
It should be taken to an authorized repair centre for a repair estimate. Very few digital cameras have any user-serviceable parts.

Please rate our solutions and if you still have problems please call back for more ideas to help you

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
