The O-MD E-M5 Mark II is, without doubt, a worthy successor to the E-M5, and surpasses all of my expectations, providing excellent image quality in a well-built and stylish compact system camera. All that’s left is for me is to pull my bank card out of my wallet so I can buy it, once I’ve decided whether to go for the black or the silver version! Something that hasn’t happened since the original E-M5, some three years ago…

Olympus has made it clear that the E-M5 Mark II isn’t meant to replace its flagship E-M1 camera, but rather act as an entryway to its Micro Four Thirds platform. With that reasoning in mind, I have no doubt the E-M5 Mark II is worth buying; I’m just not sure why anyone wouldn’t spend the extra $300 for the even better overall package that is the E-M1.

The Olympus OMD EM5 Mk II is a wonderful camera. It deserves all the praises and wonderful awards that you can possibly give it. Wifi, great image quality, a high resolution image mode to add to the future proofing, crazy fast AF, great lenses, a nice feel, weather sealing, focus peaking that works well, what more could a photographer seriously ask for?

Kai from Digitalrev has been “forced” by the m43 fanboys to review the E-m5II as soon as it gets ;)  And he actually likes the camera a lot (although he is not a big fan of the OMD design).

Macro “guru” Thomas Shahan got his hands on the brand new Venus 60mm f/2.8 2:1 Ultra-Macro Lens. On the video above he tests the Nikon mount version but the lens also comes for MFT. It is the World’s First 2:1 Magnification Lens with Infinity Focus. Thomas impressions is:

 I am amazed by the amount of detail I can pull out of this lens. I can focus on anything from a landscape to a portrait, down to a detail, down to a portrait of a jumping spider.

The lens will be on sale soon on [shoplink 51077 ebay]eBay (Click here)[/shoplink].
