Micro Four Thirds occupies a strange part of the photographic world. You’ve got people who’ll never consider it purely because of the size of the sensor, regardless of what it might be able to do, and then you’ve got the other extreme that is ridiculously loyal to the format, regardless of whether they’re shooting Panasonic or Olympus.
Along with a new MFT lens, Olympus has also announced the OM-D E-M1 Mark III camera. It’s a successor of the OM-D E-M1 Mark II, released in 2016. But other than improved in-body image stabilization and dedicated AF mode for the starry sky, this camera doesn’t seem to have any major improvements.
