The competition

An RRP of £1,249 currently makes the DSLR-styled Panasonic Lumix DMC-GH3 the most expensive CSC on the market. It has some strong competition from other CSCs with built-in viewfinders, such as the Olympus OM-D E-M5, Samsung NX20 and the Sony NEX-7. The latter two have a higher pixel count and a larger APS-C-sized imaging sensor, and as such can resolve more detail than the GH3 while maintaining a strong low-light performance. The NEX-7 has a class-leading EVF, too, with a 2.359-million-dot resolution.

As for specification, the OM-D E-M5 is possibly the most similar to the GH3. Both use a 16-million-pixel four thirds sensor, have a weather-resistant magnesium-alloy body and optional extras such as a battery grip. Each camera also has a wide range of compatible lenses – more so than the APS-C models. The GH3 is far and away the largest CSC here, although its lenses are smaller than the equivalent ones in the Samsung and Sony systems.
