I just got my speed flash, so it all new to me. On the front of the flash there are three AF sensors , My question is, should they all light up when you press the shutter button?, because only one does. Thanks,Dom.

Re: Canon ex580 speed lite
One is IR(infrared) sensor. If this one comes on, you can not see it. It's invisible to the naked eyes. Only animals, snakes and IR cameras can see it.
The red light that you see when pressing lightly on the shutter button is the AF assist light, not a sensor.

Are you sure your flash not working does affect the AF?
Check the menu for the auto focus setting, if it is still in ON.
And you did not switch off the flash yourself?
Is the lightening loge visible on the display and then the flash still does not fire?
The flash can be switched off to, for instance when you are in a museum. Check all settings. The manual must be online still with Canon USA.
I broke a lens once and just went and bought a New / Used Bounce Flash that had a uneversal flash-boot. most cameras have a flash plug in to acommidate Auto Flash Modes.
If You Know how to test Cameras and Adjustable 'Bounce" flashes like yours PAWN SHOPS are a PARADISE.
The 199A is not designed to be a wireless controller. It was designed long before wireless control of flash units was available in consumer flash units. You'll need to use the built-in flash, a more modern Canon (or compatible) controller, or some other wireless setup (possibly radio).
Okay let me get this straight, you mounted a Canon EF-S 18-55mm lens on a Canon T2. That's the Canon Rebel T2 right a film camera? If so you just can't do that because you mounted a digital lens on a full frame camera it's a wonder it allowed a manual shot the A6 is an error code for Transmission can not be made. The reason the 55-250 works is because it's a film lens or "Full Frame" where as the EF-S lens is for an APS size sensor with a 1.6 factor.
Looks like its true... Another major disadvantage. Removing TTL means removing one more hardware piece - TTL sensor. Pentax removed almost every nice feature, which needs some aditional or more expensive hardware: no TTL flash, less AF points, pentamirror... Seems like I bought Ds right in time.
