Remote Firing of Flash Units

I am trying to fire some remote flash units with my 40D however I cant fire them with the main camera flash or my Speedlight off..? Is it possible in settings to manage this on the camera..or do I need to use the remote cable that is supplied with the flash units..? Hope this makes sense...thanks Paul

The EOS 40D does not have a transmitter built in. The remote flash units must be set to "Slave" and the on-camera external flash unit (eg Speedlite 580EX) or transmitter (ST-E2) set to "Master". Note that the Speedlite 430EX doesn't have the function to act as Master and you need a minimum or the 580EX or a ST-E2 speedlite transmitter (or similar) as Master/s.

Useing a flash off a sony a300


Obviously, you'd need a separate flash unit, since you can't take the built-in flash off the camera. Just as obviously, you'd need a way to trigger that flash.

Some flash units have a remote sensor that will respond to the camera's flash. The a300 has a wireless mode for triggering such flashes. There are remote flash systems that include a radio transmitter that fits onto the camera's hot shoe and a receiver that the flash mounts onto. Some flash units have a jack so you can use a cord to connect the flash to the camera.

The degree of automation depends on the system. The a300's wireless mode works best with Sony's own flash units. The separate wireless and cord methods will work with just about any flash, though you'll probably have to set the exposure and flash output yourself.

I have a Canon EOS 40D camera. We are having problems with using an external flash. The pictures always come out extremely dark with the external flash. The flash seems to work fine, it flashes...


I don't know if this will help and this post is two months old. The camera store may be right that the synchronization is the issue which tends me to point a finger at the external flash. There are at least three different flash units that will flash when the picture is made but only one type will sync with the camera. A digital flash unit is different from a film flash so a Canon EX type is required to sync with Canon TTL or TTL II digital cameras. An EZ will flash but it's off a bit, so I can only assume that your Promaster and Canon flash units are for film cameras. Okay and another thing that could be throwing things off a bit is the camera may have been programed in Custom Functions to use "Second Curtain" or "Rear Curtain". Just seams to me if the built in flash works then it's the external units at fault.

The 580EX is firing but images comes out completely dark it just started happening in a session around 2 hours ago........i put it on another camera the 40d still the same problem what can this be?


When the flash mode TTL. Then this situation can occur if the proximity is working with other studio flash light traps. Your work makes flash another flash while TTL metering. And when is your main flash another flash did not have time to recharge.

ISO settings are basically the way the camera responds to light. The higher the ISO, the more the camera will take low light images. The trade off though in higher ISO is that you get grain.

You can use any infra red or Bluetooth flash unit, but make sire you get on that lists your particular model. That way they actually work from the amount of light that hits the CMOS sensor inside the camera itself.

Sunpak Auto zoom 3000 thyristor


You can use the Sunpak on a bracket with a "slave trigger" and fire the slave with the Nikon's pop-up flash. I do the same with a SunPak 3600 Auto Zoom. Just remember not to have the red-eye feature operating. Those little slave triggers are only a couple of dollars and I already had few brackets.
