Canon 380EX Flash Question
My brother-in-law gave me his Canon 380EX Flash, but he didnt give me the manual and it's not available online..

Can someone tell me what the numbers under teh LED light means on teh back..

There's an LED with the letters E-TTL on it. What is that for?.

Directly below that tehre is a series of LED's with numbers under each..

24 28 35 70 105.

Can someone tell me what those numbers are for? Are they a measure of flash strength? or charge? range?.

Thanks,.

The numbers (24...105) relate to the focal length of the lens on the camera. When you zoom in with a lens, the flash can zoom too, changing something (a lens in front of the bulb?) so that the flash is concentrated over a narrower field to match the focal length of the lens. The result is that you get much more range when you zoom in because the flash disperses less and is therefore more intense..

On my camera (Pentax) when you zoom in with a zoom lens, the external flash makes a high-pitched noise for a second because the flash is adjusting to focus the flash output to match the field of view of the camera lens. If the flash unit is fully compatible with the camera this will happen automatically, and when you play with the zoom on the camera you'll hear the flash adjusting to suit..

If lit, it's working in E-TTL mode. That's what your camera will do..

Lens zoom. Flash tubes moves back and forth in the head to match angle of coverage of the listed focal lengths. But these are focal lengths on 35mm, so the flash will be shooting a bit too wide on APS-C. Not a huge deal, just wasting lighting up parts of the scene the lens won't see..

There are two switches. One is on/off, that should be obvious. The other is sync speed. Normal lets you shoot at up to the sync speed of the camera (typically 1/200 or 1/250, depends on camera model). High speed (H with lightning bolt) lets you shoot at up to the fastest shutter speed the camera supports, at reduced output..

There are two lights, pilot (red) that should light up before you shoot, and confirm (green), that lights up after you shoot if the camera thinks it got a good exposure..

E-TTL is Canon's automatic ('evaluative') through-the-lens flash metering system..

Here is everything you could ever want to know, and more, about using flash on EOS cameras:.

But if you just want an easy solution for quick results, use the flash in E-TTL mode, and the camera in P mode and fire away. Or use A mode which will tend to give you longer exposures for better backgrounds - but the possibility of camera shake...

You have no choice with this flash, E-TTL is automatically used if the camera supports it, which all Canon DSLRs do..

And the camera in P mode and fire away. Or use Amode which will tend to give you longer exposures for betterbackgrounds - but the possibility of camera shake..

Or better yet M mode, so you can control how much ambient light you want. The camera has the flash automatically fill in the rest..

Ok - I didn't realise the 380EX has no manual mode, I thought it was essentially the same as the 430EX..

Better, but requires another (small) step up in understanding. I often use Manual mode myself, but for anyone who asks the basic questions I would always suggest P mode to get started, A mode to see the difference, and read the link I gave in the previous post. Maybe I should re-read it, since I got the first question wrong .

But it is true that beginners (to E-TTL flash) don't always realise that M mode on the camera is actually easier with flash than it is without...

The 380EX is almost the same as the 420EX, not 430EX. The main differences between the 380EX and 420EX are:.

- AF assist (380EX: 1 point, 420EX: 7 points)- tilt (380EX) vs tilt & swivel (420EX)- 420EX can be an E-TTL wireless slave- 420EX has a bit more power.

Both the 380EX and 420EX are fairly basic auto-only flashes. The 430EX is a pretty big upgrade..
