Hey everyone.

I have a one lens that works fine without flash, but as soon as I use flash it just gives me an error. All my other lenses work with flash.

Any idea what might cause this?

I'm using a 70d

Probably helps to list the model of the flash and lens as well.

But make sure you try to update to the latest firmware on the camera first.

The flash is just built in.

Lens is a tokina 12-24 AT-X pro

It works fine on my T2i..... But every other lens I have works fine on my 70d

You are on manual setting and forcing the flash to fire and it still doesn't work ??

If it is on auto, chances are the lens is pretty wide at F4 and 70D is pretty capable in low light compared to the T2i, the metering on the camera may be reading that it doesn't need to flash so it doesn't.

Just in case. Have you tried a fully charged genuine Canon battery ? I found using the after market battery would slow down the focusing speed on a Sigma 150-600, my keep rate is way up when I switch back to Canon battery. I think T2i battery / camera system is different.

So an update.

Lens works just fine in flash if I shoot in auto. It is only manual modes that give me an issue. Happens at all focal ranges too

What's the error message that you see on the screen?

It doesn't make sense that it works on auto but you're getting an error message when in manual mode.

I don't remember how it works in manual mode but the flash may not pop up by itself when in manual mode (which means the flash is turned off and won't fire). Did you press the button on the left of the flash to force it to pop up? I think it has the lightning bolt picture.

It's err 01 which as far as I can tell is just a general lens communication error. Fixes online say to wipe don
Wn the contacts, but that doesnt work.

I have manly opened the flash in all test cases

Do you have a friend who has some other Canon camera that you could try (that is not a T2i, T3i, etc)? Or maybe walk into a camera store like Henry's to see if they have a spare body that you could try the lens on. Or maybe somebody at Henry's might have an answer.

Edit: I did a Google search for Error 02 and it says it's a memory card error. Not a lens error. Try taking the memory card out, formatting it, pop out the battery, and then put it back in. See if that helps. Or was that a typo and you meant you are seeing Error 01?

since it works on auto mode, perhaps it's the shutter speed set to above the flash sync speed

Yep I definitely meant err 01
