Dears,

Please support me with the problem appeared as I just jumped from A900 to A99 II.

Observation:

With flash HVL-58AM connected via original Sony ADP-MAA to A99 II I set body to A mode and try to photo in low light conditions. Flash to REAR, works well, ambient and flash exposures also OK - separate and/or combined.

BUT: camera measures the exposure and set shutter speeds like 1 or 2 seconds or longer. ISO set to value or ISO Auto, all types of metering, still the same. Blurry photos guaranteed with long shutter speed.

Comparison:

My A900 in the same mode (flash on in REAR, A mode) set shutter speed from 1/250 in bright to 1/60 in low light conditions, I can set the aperture and esposure corrections, but shutter is never longer then 1/30s!

Question:

How to persuade A99 II to not go with shutter longer then 1/30s in A mode with flash on?


Thanks in advance!

Do yo see a flash ready sign in your rear LCD or viewfinder appearing once the flash is recycled ?

Does the flash actually fire with this 1-2 sec shutter speed ?

If not, there could be a contact issue either between flash and adapter or adapter to body that does not let the body know the flash is there causing the improper shutter speed.

Maybe I don't completely understand the issue, please clarify if I got this wrong.

The A99II rear sync seems to work as intended, the camera exposes for natural light and then fires a flash before closing the shutter curtain to freeze motion (showing motion trail). If this effect is not desired, either use regular fill-flash or with rear-sync turn on S-mode or M-mode to fix shutter speed. The latter would essentially do the same as switching to fill flash except with rear instead of front curtain sync.

I'm not sure why the A900 would behave differently in rear sync mode, exposure times mentioned are way too short to get motion trails.

Try setting the "electronic front curtain shutter " to OFF .
That might be the issue , your a900 didn't have that feature , and your flash predates it too .
Maybe that's what's causing the issue .

The only way a DSLR ( and presumably an SLT) would behave that way is if you press the AEL button which causes the camera to expose for the ambient light and then fires the fill flash .
Your not pressing the AEL button are you ?

C & C welcome.

Dear 9000AF,

You are right.

When I switch to Fill Flash the A99II in A mode behaves as my old A900; shutter speed is not longer then 1/60s even in low light.


Thanks a lot.
