The E-M1II with the new 12-100mm PRO and 25mm PRO lens at CameraSize.

Closer Look by Engadget:

While I’ve only been testing the camera for little more than a day, all of those specs have translated well in real-world use. At least so far. As advertised, the E-M1 Mark II makes capturing moving subjects a breeze, especially compared to its somewhat aging predecessor. That’s namely thanks to the new AF system and improved tracking performance. I also noticed right away how much heavier it feels than the original E-M1, likely due to the bulky 1,720mAh battery, which Olympus claims can handle around 440 shots per charge.

iZugar’s tiny fisheye lens fits M4/3 and Sony E-mount – works well for VR (Newsshooter).

Leftovers from Photokina: Newsshooter played a bit with the iZugar’s tiny fisheye lens that fits on MFT too.

Luminous Landscape posted their E-M1II preview and writes:

No question — this a great camera.  It’s loaded with features that some people might never use.  However, if one takes the time to become familiar with the camera and its many features, then a photographer would find this to be a very versatile camera that can produce nice images in a small, lightweight camera.
Yes, I will buy it.  Somewhat reluctantly because of the price, but I am vested in the lenses, and this camera will just make my investment that much better.Plus, it will be a nice Christmas gift for my wife (Don’t tell her). I hope that we see some firmware upgrades in the future to fix the minor but important concerns I have pointed out.

This isn’t a camera that every M4/3 shooter needs, but it’s a fantastic option for professionals to upgrade into. While US$2,000 makes sense for existing M4/3 shooters that are interested in the sheer speed and power of the camera, this won’t convert any photographers using other mounts to the system. 

Imaging Resource posted the in depth image quality analysis. Comparing with the E-M1 at Base ISO they write:

The resolution advantage of the 20-megapixel E-M1 Mark II is apparent here compared to its 16-megapixel predecessor by virtue of the larger scale of the images on the left, but the E-M1 II also resolves more fine detail while showing similar if not slightly lower noise levels. Detail in our tricky red-leaf fabric pattern is less defined from the E-M1 II, though, due to what looks to be stronger noise reduction, however another reason is the increased resolution renders more of fine thread pattern which tends to break up the leaf pattern a bit more. The E-M1 II also appears to apply slightly stronger default sharpening, as well as slightly higher contrast and saturation than the E-M1, but in other respects, both cameras offer very similar image quality at base ISO.

Imaging Resource published the full review of the new 25mm f/1.2 PRO lens:

This is a premium lens, with a premium price. Fortunately, it’s worth every penny, providing optical performance worthy of the price tag. Generally, you know if you need a lens with this huge aperture size, and it’s not for the feint of heart: the razor-thin depth of field that’s presented when shooting at ƒ/1.2 demands a strict technique. But when used well, the results are exquisite.
