Hi all,

I was looking at the Sigma EF500 super flash for my Canon G2.

When I tried it out at the store with my G2, they all gave under-exposure (about -2 stop) even on E-TTL mode direct flash. Thinking it may be due to a faulty unit, I requested another unit which gave the same result.

I then tried out the same set of batteries on the Canon 420EX. This time I got good exposures.

Did anyone have the same problem with the Sigma flashes? Or could it be that it is not compatible with the G2?

Any help appreciated.

Thanks!
