    I figured out how to do it by taking the flash apart carefully.  If anyone has the same problem in the future.  I am happy to help.  I plan to develop video clip on how to fix it after much time devoted to search for instruction on the Internet and I found nothing.

    The flange of Canon 550 EX flash hotshoe (that fits onto the camera hotshoe) broke today.  Another post listed the following information " i did the same with my 430ex ordered part from url above. need to do a little soldering though."
    Does the above link provide genuine canon parts ?

    Is this hard to do ?  I have neither a solder nor any experience doing such things>

    Would a local camera shop do this ?

Hot shoe plastic section broke on flash unit

I managed it by buying a broken (non-working) F32X from an auction service for something like 5 bucks. I just made sure (by looking at the photos) that the hotshoe was intact.

Here's how to disassemble and replace foot (I got to this by trial and luckily no error ^^).

  1. Unscrew 2 small screws located under the battery flip cover.
  2. Put the lamp (moving part) in the upright position.
  3. Unscrew 1 small screw above the infared sensor (below the main lamp part which you moved to the upright position).
  4. Remove the cover of the infared sensor by gently pulling forward.
  5. On two sides of the infared sensor there are two small clips which hold the 2 casing pieces together. Pull them away from the casing just a tiny bit and use something to keep them in this position (I used 2 small nails). Then pull the pieces apart gently.
  6. Just behind the hotshoe casing you can see a small plastic inset -- place a screwdriver sideways between this inset and the hotshoe to help you separate the two casing parts. Be careful when doing that, don't use too much force, wiggle the casing instead to make this easier (this is the most tricky part).
  7. When the electronics is exposed, there is a single screw in the middle of the motherboard. Remove the screw and gently pull the motherboard away from the casing. You do not have to pull it all the way or disconnect any cables, you just need to make sure the bottom battery connectors are pulled out of the casing just a little, because then under the two middle battery connectors (looking from the top, as if you were putting the batteries in) you can see two screws!
  8. Unscrew those two screws, and the hotshoe will come apart. Pull it out gently and remove a single electrical connector that connects it to the flash.
Do this in case of your working lamp (with a broken hotshoe) and your replacement lamp (with a good hotshoe), and just move the good hotshoe to your working lamp.

Took me about an hour to do this (most time was spent on trying to figure out how to disassemble the lamp), and the lamp works perfectly.

Warning: better test disassembly on the replacement lamp, since even if you break it, all you need it for is the hotshoe, so you can practice on it. Only after you learn how to disassemble the F32X do this on your working lamp.

Hope this helps!

Switch from film to digital cameras.

I also own a Vivitar 285 that i used with my Canon F1 manual 35mm camera. Most older cameras before the advent of digital, had a hot shoe on top of the camera, or like in my case, the hot shoe went over the rewind knob. I also had to plug in a power cord from the 285 flash foot and the cameras PC connection in order for the flash to work on some other cameras. The Canon Rebel XTi has a TTL (through the lens) hot shoe usable with Canon's own EX flash units. You can buy a "hot shoe to PC connector" if the TTL camera hot shoe doesn't work, but be extremely careful, the only problem that exists with the older manual flash units was the trigger voltage is as high as 200+volts which would fry digital camera hot shoes. I tried my unit with a Wein flash trigger device on the PC cord of the flash and my Canon D60 with it's own flash. All shots were overexposed and washed out highlights.  Here's a copy of the hot-shoe review:h The EOS 400D's hot-shoe can be used with Canon and third party flashes (although sync only on most third party units). The hot-shoe is E-TTL II compatible. Compatible flashes include Speedlite 220EX, 380EX, 420EX, 430EX, 550EX, 580EX, Macro-Ring Lite, MR-14EX, Macro Twin Lite MT-24EX and Speedlite Transmitter ST-E2.  The Canon Rebel XTi doesn't have a PC socket to plug in a manual flash trigger cord which common sense tells me there is no provision to step up the voltage to trigger manual flashes - so my answer is this combination is not a good idea on a Canon Rebel XTi. Hope this helps.

Canon SPEEDLITE 580EX - How do I replace the hotshoe mount?

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.

550ex PC sync socket conversions

I do medical/photo equipment repairs & IR conversion, but I'm in the USA.
Over 20 years and Canon knew about that problem including many photographers. Most of Canon flashes can not do manual or aperture mode because they have to flash sensor.
Now they have it on the 580EXII. I guess Canon has no photographer working in the flash department.

Canon screwed photographers, buy a Metz, Vivitar, Sigma, Sunpak, or NIkon.

Could I use my Canon bounce flash (550EX) with this Olympus Digital camera?

That's not possible because the hot shoe is not provided for the Canon hot shoe. You can change some wires in the Canon flasunit to let it think is an Olympus model ;)
