Guide value

1battery charge

On paper, the battery in your camera is enough.

A guide value, not a guarantee: based on approx. 950 shots using the viewfinder per battery charge (CIPA figure from Sony for the Alpha 550, a standardised comparison test). According to Sony, the actual runtime depends on the conditions of use; we have not measured these figures with Baxxtar batteries.
