I use the Meike battery grip...
Thanks DS... sadly no odd bug, this was reported on the different sites before purchasing and I even asked about it on this very form (perhaps its previous incarnation) about this Error 50 with the built in flash
.
My grip is the Opteka one... also as close to the Canon as possible.
Now, in this case I didn't see any battery depleting at all, just an Error20 after the Error50. I'll avoid using the built in flash this time and see if there is a better indicator on this new batteries I just inserted.
For all the folks reporting on this, could you please provide info as to whether you are using 1 or 2 batteries in the Grip?
Thanks again,
Rafa.
