Olympus' followup to its excellent, a mirrorless model for newbies who want a viewfinder, is more of a Mark II-plus than a Mark III. There are a few tweaks to the design and a new effects filter, but the biggest change is the updated interface for beginners -- intended to be easier to use than the old supposedly easier-to-use interface.
The Olympus OM-D E-M10 Mark III is slated to ship at the end of September in a body-only version for $650 and with a kit including the 14-42mm EZ lens for $800. I don't have UK or Australian pricing, but those directly convert to about £500/£620 and AU$820/AU$1,010.
Thanks to an update to a more recent version of Olympus' processing engine, there are minor improvements in performance, such as an increase from 4 to 4.8fps in continuous shooting with autofocus, a higher ISO sensitivity available when using auto ISO and improved autofocus.
For ease of use, Olympus has broken out some of the less frequently used modes into a new Advanced Photo mode and revamped the basic interface so that it now looks like the guided-by-pictures type that's used by most entry-level cameras these days. Sadly, I think the most welcome change after the grip is the addition of a shortcut button, which takes you back up a level in the menu system when you're in the settings.
