The mockup we've seen is non functional, but initial hints at its specification are intriguing. The new OM-G is built around a 36MP full-frame BSI-CMOS sensor and is fully compatible with Olympus' classic manual focus OM lens lineup, with no crop factor. 

Mockups have been published showing a new Olympus OM-D OM-G. Apparently released to mark the 30th anniversary of the original film OM-G (marketed as the OM-20 in Europe), we understand the newest member of Olympus's OM-D family will offer full native support for legacy manual focus Olympus lenses, and will be built around a full-frame BSI-CMOS sensor.

Key specifications:

  • 36MP full-frame BSI-CMOS sensor
  • ISO 25-800 (via optional drop-in cartridges)
  • Hybrid electronic / optical viewfinder
  • Full support for legacy MF OM lenses
  • '6-axis' image stabilization
We understand the OM-G will feature a full-frame BSI-CMOS sensor - the largest sensor of this type we've ever seen. Although unconfirmed, we'd expect Olympus to offer an adapter to allow use of newer M43 lenses, albeit at an effective resolution of around 9MP. 

ISO sensitivity will span 25-800 via insertable cartridges (optional) and with the OM-G, rumors say Olympus will evolve the existing 5-axis image stabilization offered in its flagship E-M1 with an additional fore / aft axis. This sixth axis will correct for subject or camera movement in the horizontal plane. Although unconfirmed, in theory this system could also be used for automatic focus bracketing - potentially very useful when shooting with fast prime lenses wide open. 

Rumors suggest the OM-G's viewfinder will be a hybrid optical/electronic type, with the former mode featuring a ground glass focusing screen. Despite the increase in the size of its sensor compared to Olympus's M43 mirrorless interchangeable lens cameras, the OM-G retains an unbelievably slim form factor. 

There's no word on pricing or availability yet and details on the new camera's specification are thin on the ground for now. You can be sure though that we'll be updating this story regularly as more information is confirmed by Olympus. Let us know what you think in the comments. 

UPDATE: Despite the incredibly high quality of the Photoshopping in this story, as many of you had guessed it is an April fool. The OM-G was a very real camera, back in 1984 but it's unlikely we'll see it reincarnated.
