A6000 Flash top power
« on: November 16, 2014, 08:29:06 PM »
Thank you to those who have already awnsered my other questions. Here is another :)

When I am using off camera flash(YN 560 II), it fires fine, but when it gets to 1/2 power, for some reason the camera doesnt register the flash and gives a black exposure.works fine at 1/4 and below.

I'm not sure if it makes any difference, but how are you triggering the YN-560 II to fire off camera?

Does this happen on every shot, or is it OK at full or 1/2 power on the FIRST shot, but dark thereafter?
If this is the problem (IE OK on first, but dark therafter), it may be you are not giving the flash enough time to recharge - the YN-560 II is pretty fast, but still needs 2-3s after a full power flash before it can fire again.

What shutter speed are you using? (too high a shutter speed can cause problems with flash).

My settings are 1/160, F8 and Iso 200.

The flash all the way from 1/128 through to 1/4 works fine, its only when I up it to 1/2.

I thought it might be the extra power is taking the flash to long to power up and flash, but that cant be it.

It seems that this flash work only in manual mode so no TTL. If is like this then you have to use the camera in aperture priority or in M mode to fully control the flash output.

Figured it out, I was triggering off the camera flash, tested on wireless trigger, and it worked fine. It's something about the on camera flash. Timing isnt quite matching up.

Where you using the on-camera flash in 'wireless' mode, or just as a normal fill flash, and the YN-560 II in optical slave mode?

If the latter, try switching between S1 and S2 - particularly if the on-camera flash has any secondary flash enabled (normally TTL, but if there is anything like red-eye reduction enabled, this could fool the optical trigger).

I always use wireless flash with my YN 560-II (the A900 doesn't have a built in flash), and it performs flawlessly - it's a great flash for the price!

I normally use wireless trigger aswell, but due to a fall, the lip at the bottom of the trigger snapped off, so was have to do some gluing on it.

On a seperate not, I love the A6000 for having a movable flash so your able angle it away from the subject. Can really nicely bounce it off a wall without having to pull of the 560II
