Which camera should I buy?
The mid-range mirrorless camera market has a rather large price spread, and thus includes cameras that touch both the entry-level and higher-end categories. The build quality and handling of all these cameras tend to make them worth the extra money over cheaper interchangeable lens cameras.
So, whether you're looking for a second camera to sit alongside a high-end DSLR that you can't carry with you all the time - or desire an alternative to buying a DSLR altogether - there's plenty to chose from. Because of the large price spread, we offer two suggestions: one for the 'money is no object' photographer who wants the best camera in this class, and another for those looking for capability on a budget.
The Olympus OM-D E-M5 has a well-designed, weather-resistant body, and 'guts' that produce very good image quality, and rocket-fast autofocus. We like the tilting OLED display and the sharp electronic viewfinder, as well as the amount of customizable functions. Downsides include poor subject tracking, small and cramped controls, and a potentially overwhelming array of custom options.
With its excellent kit lens, sterling image quality and improved focus, the Fujifilm X-E2 is also worth considering - especially if you're looking to shoot with legacy lenses. But, despite a couple of flaws - and its being over a year old - the OM-D E-M5 remains atop the mid-range mirrorless pack.
If you don't want to spend a bundle, then we recommend the Panasonic Lumix DMC-G6. The G6 costs substantially less than the E-M5 above, yet doesn't skimp on features. It offers solid image quality (though you'll get best results by using Raw at high sensitivities), a great auto mode, a fully articulated LCD and a competent electronic viewfinder, along with 1080/60p video recording. We're not a huge fan of its plasticky body and cluttered controls, but overall, the G6 is well worth considering.
