Bruce, Try these steps: 1. Set camera to manual2. Set shutter to 1/60 3. Set aperture to F5.6 4. ASA/ISO 200 5. 550EX on hotshoe 6. Do not set on slave or master 7. Turn on flash
Display must shows, ETTL. If that doesn't work, you have to use the flash on manual. Some of this model will not work fully on ATG Canon EOS-1D C, ATG Canon EOS-1D X IR, Canon EOS-1D X/60D/T4i because this flash is over 20 years old.
Unless you would want it to be modified by me. But that can be costly when you can get the 580EX II for less than $425.00 USD.
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
These instructions are for the 550ex and I imagine that the bodies of the flash units are the same.
As with any project, make sure to get a good workspace with plenty of light where you won't drop any screws and lose them...
1) There are 4 screws on the bottom of the flash unit that you'll want to unscrew first. Carefully tilt back the bottom section away from the red filter which covers the "eye".
2) There is a set of wires going to a white harness in the piece you just tilted off which you can carefully disconnect with a small flathead screwdriver working it on either side.
3) The same type of harness attaches another set of wires but this one is just inside the body of the flash in the cavity you just opened up. This one is a bit wider and you should undo that harness in the same, careful manner.
4) Next, you have to remove the master/slave switch which is attached with two small screws that you'll need to carefully undo. The actual switch is attached to the tiny board you are unscrewing. There is a plate covering that switch that is the piece you actually push when you want to switch it. That piece will come out when you take the actual switch out so remember which direction it went.
5) Now you should have exposed four small screws as you look straight down into the piece you're working with. These screws hold on the shoe you're replacing. With some decent force against the screws, carefully unscrew them. These don't come out very easily so you want to make sure you have the right sized screwdriver that fits and that you're applying some downward force. MAKE SURE you don't strip the head on these screws.
6) Turn the whole piece so that the shoe is facing upwards. Now you can carefully pull off the shoe. Make sure to not lose the loose spring that is under this thing. You'll see that there are 5 prongs sticking up, a horizontal metal piece, and a small rod looking piece with a spring that fits over it. Take note of how these all go so you can put the new one on with those pieces in the right places.
7) Put the new piece on and screw everything back in the reverse order. Voila! You just saved yourself a bunch of money and hassle. Thanks for the tip on where to get that piece, by the way, I had been looking around for it.
Hello, after breaking mine this morning I was able to fix the flash so It can fire from the hotshoe.
Any automatic TTL features will still not work however atleast you will be able too fire in auto, and manual modes.
I simply opened the flash by taking off the hotshoe, and then swiveling the flash head 90 degrees to expose the four screws there. You need only remove the two screws from the front side of the unit.
Open the battery door and gently pull away the front case (Be careful there are several delicate ribbon cables that you do not want to snap. From here you can either unscrew all the ribon cables to free yourself room to solder or try and dodge them.
You should now be able to see the rear side of the PC sync socket. There is a blue wire that joins the outer edge of the socket - this is ground. Solder onto this point and join onto the top left circle of the PCB board of the hotshoe. (Opposite corner from where the ribbon cable attatches) There are copper circles exposed on the pcb for easy soldering.
Next, return to the rear of the PC sync socket and note the orange wire coming from the centre pin. Solder a wire to this point, and then down to the hotshoe PCB and to the circle that joins to the centre pin of the hotshoe. (Trace the circuit paths)
Sorry I did this about 30mins ago and I'm remembering this out of my head.
