For me quite ok.
When to tg. Pinang last week, shoot for 2 days without charging it and back to SG with 20+%.
FYI im quite hardcore, i shoot what i see over there. LOL.
True, the battery depletes quite fast as compared to my ex GF-1 and EP-1.
Sorry if it's OT.
I'm curios to know why you chose NEX5 over the GF1 & EP1. I'm looking to retire my old Nikon D50 with one of these. No time for serious photography and weight is my concern. Care to share your comments? Thank you.
