The Hawk Woods DV-F990 – like its smaller siblings (DV-F590 and DV-F790) – is a Sony NP-F (L-Series) battery alternative, and all three models are delightfully dense in the context of their peers. The DV-F990, which is no larger than Sony’s NP-F970, houses an impressive 10,200mAh (74Wh) of energy in lithium-ion cells – that’s almost double the capacity found in a Sony NP-F970.
