First E-M1 and 12-40mm session by Pekka Potka (Click here):

They form a very balanced and capable tool. Of these two, maybe the lens is more important for me as it gives the best combination of portability, handling and optical performance for the focal length range I use most. E-M1 is in many ways an overkill for me. I need so few of it´s features. But on the other hand it surpasses E-M5 handling and performance in many areas which I find valuable. One feature which I find outstanding is the improved stabilization.

New review at The.me (Click here):

Overall conclusion: Very, very good. Almost impossible to disappoint. Olympus as I said has a long history. Without doubt it also has a long future.

Also Imaging Resource (Click here) posted their full E-M1 review:

The Olympus E-M1 delivers the sharpest, most detailed JPEGs we’ve seen from a Micro Four Thirds camera — if just by a hair over the E-M5 and E-P5 — with image quality that rivals that of most high-end APS-C DSLRs and CSCs. And despite its comparatively small chip size and 16-megapixel resolution, the E-M1 does especially well in low-light situations at high ISOs, with its JPEG processing outshining that of the top enthusiast,

The Olympus 12-40mm got tested at SLRgear (Click here):

Olympus has shown that it can make a lens with the optical quality as well as build quality that these users demand, and professional photographers such as photojournalists and adventure photographers should take note.

Dpreview (Click here) added the GM1 test scene samples and it looks like there is one small surprise. The images of the Gm1 appear to be tiny bit sharper than those of the GX7. Can’t say if that difference is here because of some slighty different test conditions or if the GM1 has indeed an improved processing engine.

In US at Amazon, Adorama, BHphoto.
In Europe at Amazon Germany, Wex Germany, Amazon UK, Fotohanskeuzekamp, Cyberphoto Sweden and Wex UK.

This is Kai’s take on the new Olympus E-M1. He is not known to be a real MFT fan. I am glad to hear he changed a his mind thanks to the E-M1 :)
