My first 4/3 camera!
Micro Four Thirds or MFT or m4/3, etc. not 4/3 which refers to older, mostly DSLR cam
Congratulations. The GX7 is an unusual and very nice camera!
True, but give the OP a break. It's m43 due to the flange, but it uses the same-sized 43 sensor as those in both m43 and 43 cameras.
