Canon 430EX Flash

I purchased this used flash without a manual for my son who lives in another state.  I don't have a camera to try it on, I'm a Nikon user so I'm not familiar with Canon equipment.  The ready light comes on and it test fires.  My question is, does the flash have to be mounted on a camera in order to see if all of the functions work.  The zoom setting is at 14mm, and nothing happens when I push the zoom button, also nothing changes when I push the + or - buttons.  Any help would be appreciated.

    Just purchased one from Adorama and when mounted on both a 40D and 350D it is set at manual 14 and won't budge when I press the zoom button and turn the wheel.

I have a 430ex and S5, I don't think the zoom head will move without being mounted on a camera.

If the flash test fires ok, then it should be fine.

Want to buy a flash to mount to the camera

The SX10 has a standard flash mount, which will fit just about any flash unit. The manual recommends the Canon Speedlite 220EX, 430EX II, or 580EX II units. Other manufacturers' flash units will also work, though perhaps not as automatically.

The big thing to watch for is that older (film-era) flash units may have higher trigger voltages that can fry newer digital cameras. Before buying such a unit, check this list.

When I take a promaster remote flash trigger system with my canon 430ex half of the picture is exposed. What am I doing wrong?

this is most likely a sync issue. you shutter speed is too high. try lowering it. 1/200 or 1/160 of a second should be fine for your case.

No wireless on my 430ex flash

This Canon flash gun does not have a true wireless (radio) trigger. It uses optical light pulse.
A user manual can be downloaded from this WEB site.

Trigger a Speedlite 430EX II with a studio flash

  1. Make sure the trigger you are using is compatible with digital flashes.
  2. isolate the smaller contact so they do not "short out" on the trigger.
  3. make sure the trigger is working and will fire other flashes

I just bought the 430ex II flash and it won't fire on my Rebel XTI.... i read the manual but I'm not sure whats wrong, have any advice?

I assume that flash is turned on. 430ex flash will fire automatically only in AUTO mode. On manual modes you mus manually force the flash to fire.
If flash doesn't fire at all, consider to claim the vendor or let the vendor to check the flash mounted on your camera.

Make sure it is not set to manual 'M' on the display. To get it to shoot in ETTL (Through the lens) press the mode button and it should read ETTL in the top left corner. This then means that the light is metered thorugh the lens and you are not relying on the manual settings.

Hope that helps. I had the same problem when i first got my.
By the way a brilliant all round bit of kit. I have traveled the world to some fairly extreme temps and got it wet (Rain, humidity, sea spray to deserts and serious dust) All good.

Good luck
