Its answer, the OM-D E-M1X ($2,999, body only), is a mirrorless model with a smaller Micro Four Thirds imager, but built like a pro SLR. Its design incorporates the integrated vertical grip preferred by many pro sport shooters, and dual processors add more advanced subject recognition and tracking to its autofocus system—for some subjects, at least.

When the E-M1X is playing to its strengths, it's a top piece of kit, but the best way to describe it is "niche".
