Re: BP-21 vs BP-22... what?!?

That probably nailed the reason for the change - thank you! Probably points to some of the Li-Ion battery issues that the laptop computer makers had last few years. They might be limiting energy density to reduce fire risk, hence the lower total power rating.  That's kinda sad, as the Sigma DSLRs aren't the most power-efficient.  One more reason for the PG-31 power grip, I guess.

Oh, and there is a BC-22 charger, too. The casing is a bit "blockier" than the BC-21 - the big chamfer around the bottom of the case, and the big round fillet at the top of the upper case cover are gone... other than that, functionality seems to be exactly the same.

Headed down to Carmel, CA tomorrow; not sure if I'm more excited about the trip, or taking the SD1M with me!
