Panasonic as anticipated switched its focus back to more experienced photographers with a new compact Lumix Micro Four Thirds camera. The GX1 is the first in the small-body series to get an upgraded 16-megapixel CMOS sensor and has better low-light performance along with an ISO 12,800 sensitivity ceiling. Customization is also once again more important: it now has C1 and C2 modes that support a total of four user presets, two programmable buttons, and a thumb wheel.
