The Japanese site DC.watch (google translation here) is the worldwide first site posting a preview of the Olympus AIR MFT camera. As you know the AIR will go for sale in Japan only. ON their site you can find a full ISO test and many image samples. The AIR uses the same 16MP sensor as the other OMD cameras. And here are some of the reviewers impressions:
1) The AIR has no on sensor stabilization because Olympus wanted to keep it as compact as possible
2) Start up time is a bit slow
3) Autofocus is fast
4) Connection with the APP is fast and reliable. And the cool thing is that everything is OPEN source which means everyone can develop an APP for the AIR (unlike Sony QX which is closed source).
It will be interesting to see if that new AIR MFT camera will actually make some significant sales in Japan…
