So this just happened today
I connected my 580EX to my camera and for some reason the sync speed that suppose to go up to around 200/sec, just remained very low.
I was in a fairly dark room so it remained at around 5 seconds.
I tried switching the flash on and off and it doesn't effect the sync speed at all.
Here are my settings:
Mode AV
Iso 100
Flash is on ETTL
No compensation on camera or strobe.
No custom functions are on

Switched to fresh batteries, didn't help
Checked that I'm not on slave or matter mode


Here is something I noticed though, the distance meter is way off, it shows that my subject is over 30 feet away when my subject is right in front of me, maybe 2 feet.

Any help will be great, I just bought it here on the forum and it was working fine for a week and now I feel like my money goes down the drain.

Thanks

Possibly a malfunction on one or more contact points.
Replacing the strobe could do just the thing.

Had a similar situation with a 5DIII where the 580EX (for some odd reason) stayed on TTL. No matter what I did It didn't change untill I replaced the strobe.

Two days ago I used the 580EX with the 5DIV without any problems (different settings all worked within parameters, including syncro).

Good luck.

Greetings, Alain

Check the function: 'Flash sync speed in Av mode'.

Remove and replace flash. Sometimes they don't slide all the way into the shoe.

Hi Guys,

Thank you for the replys.

I am assuming its a malfunction.
Checked the setting you were talking about Bassat, its on Auto so it should work fine, and tried replacing batteries and taking the strobe out and putting it agian but nothing, I guess I will have to buy a new one and just try to have this one fixed.

Thanks again

On AV the camera is exposing for the ambient. Either increase ISO to 3200 or higher, switch to M and fix the shutter high as you want or or flick to P mode where the camera will default to 1/60th sec.

The camera is behaving properly. If you want to control shutter speed and aperture, switch to MANUAL mode. It is the preferred mode for flash.

so, If my camera is set to AV, my sync speed will not automatically switch to at least 1/60th of a sec when I connect my strobe ????? I feel so dumb right now. I usually work with external strobes and pretty new to onboard strobe, but still, this is something I should have known.
