Default A700 external flash issue

I purchased a Sigma EF-500 flash to use om my A700. I use it for both low light shooting and fill flash. I expected the power of the flash to be better than the flash on the camera.

I must be missing the setting on this. I usually use 100ASA and program mode on the camera.

I am definately having a difficult time getting things lit.

Anyone use this combination and have good luck?

did you purchase the Sigma EF-500 DG (or DG Super)? It must have the DG designation to work with a Digital SLR.

I had compatiblity problems, even with the DG version. It would not get the exposure right, mostly firing at full power. It is certainly a LOT more powerful than your built-in flash.

Its the DG super. Here is an example. Yes, it was very dim in the room, but I was not too far from the wall when I shot this... maybe 5 or 6 feet. If I use the camera flash, its OK but Im missing something on the sync with this flash, just cant find it... Im having the exact opposite problem... not enough flash.

I ended up returning mine, twice (!), once after I tried it with my Maxxum 5D, recently I tried it again on my Sony A300. It would expose just at its own whim, not communicate with the camera. I exchanged it for the Vivitar DF-383 which is now also giving me problems and doesn't communicate with the camera most of the time. When you use your flash does it indicate if or not it is in sync with the camera?

There is no direct "sync" indication, but you can tell if the flash and camera communicate. Does the zoom in the flash move with the lens?
