Rebel T5i trying to use a flash diffuser for pop up flash

I have a rebel t5i and am trying to use a flash diffuser for the pop up flash. It attaches to the camera using

the hot shoe. When I slide the diffuser onto the hot shoe, the flash will not fire. If I slide the diffuser half way off the 

hot shoe it fires. I am assuming it has something to do with the contacts on the hot shoe. The diffuser attachment that

slides onto the hot shoe is plastic. Is there an override so I can get the pop up flash to fire with the diffuser on the hot shoe?

Thanks.

Re: Rebel T5i trying to use a flash diffuser for pop up flash

I am having difficulty picturing what sort of "diffuser" you are talking about.  I have never heard of a diffuser designed to use with the built-in flash, which doesn't mean no one sells them.  I've just never heard of one before.  It almost sounds like you may not be using the right gear to achieve your objectives.

 

The hot shoe has several contacts.  The camera can use those contacts to determine when something is attached to the hot shoe.  When the camera does detect something on the hot shoe, it may disable the internal flash.  In fact, it should disable the internal flash because the built-in flash must swing upwards, and will Mose likely strike whatever is on the hot shoe.

 

I don't have the T5i, but check the menus for options to use an external flash, or the built-in flash.  I know there should be a setting to disable the internal flash.  There might be one to disable the hot shoe, if your "diffuser" does not need to make an electronic connection to the camera.

There is a micro-switch on the camera flash shoe.  When something is mounted, the switch is depressed telling the camera that there's an external flash and do not pop up and use the built-in flash.  So this flash diffuser is using the hotshoe which is the wrong thing to do...I don't think there is a way to disable the micro-switch but check your manual for it anyways.

 

My advice is to do away with the built-in flash and invest in an external flash you'll be glad in the long run.
