The Specs and Design of Olympus OM-D E-M5 Mark III Camera

Written by Nanuduke

The E-M5 III shares the same 20MP Four Thirds sensor and 121-point hybrid AF system as the E-M1 II, compared to the 16MP sensor and 81-point CDAF system of its predecessor. It also inherits the E-M1 II’s AF algorithms, though not the machine learning AF mode introduced on the E-M1 X. The image stabilization system has been redesigned to take up less internal space, yet should offer a 0.5 EV improvement over its predecessor, giving it a CIPA rated 5.5 stops of stabilization or 6.5 stops of when using either the M.Zuiko 300mm F4 or 12-100mm F4 Pro.

It’s the first  of its kind in the E-M5 line to offer on-sensor phase detect auto-focus, comprising  face and eye detection modes. The updated AF system is complemented by a 10 fps max burst rate in AF-C. The camera also gets a new image stabilization system, an updated EVF and some small ergonomic improvements.

The E-M5 Mark III looks like a slightly smaller version of its predecessor as reviewed earlier it is compact enough for one-handed operation – at least with smaller lenses. The twin controls dials are perfectly placed, and the numerous buttons on the right side of the camera don’t require fingers stretching to operate.

Despite its size, the E-M5 III feels solid in the hand. Its body is a mix of metal and composites, and it’s wrapped with a faux leather that’s a bit slippery. As with its predecessor, the E-M5 III is sealed against dust and moisture (it’s rated to IPX1 standards), and is freezeproof to -10°C (14°F).

The camera’s top plate is loaded with switches, dials and buttons. The Drive/Display/Power switch combination is borrowed from the E-M1 II and replaces the mode dial, which has moved to the right. The mode dial now has a Bulb setting, which is where you’ll find the Live Bulb and Live Composite features.
