>>2938909The GR II adds wifi and a slightly raised ISO ceiling.
The GR is great for a couple of reasons (I recommend you read reviews)
- APSC sized image sensor (same size used in most DSLRs, except in a much smaller package)
- Excellent ergonomics (you don't think it'll matter until you hold one)
- Really good optics, sharp edge to edge even wide open
- Excellent software, uses Adobe camera raw so easy editing
- No image lag, as well as zone focus mode
Honestly just read a couple of reviews and do the research for yourself. It's the best of the best in it's category, hands down
