Most XG-1's are not working now. I got one a year or so ago. It wouldn't work. So I set out looking for a replacement body since the lens seems very nice. But 80% of the XG-1's I see listed are for parts/repair. (meaning junk)
I gave up. Maybe there's a better model to seek out?
Like others said there must be good batteries for the XG-1 to work. If you want to use the lens that came with the XG-1 you can get the SRT-101, 102 etc.. series cameras.
