9 High-Performance Professional Mirrorless Cameras

9 High-Performance Professional Mirrorless Cameras


Mirrorless interchangeable-lens cameras (ILCs) have really come of age over the past few years. They’re now a leading choice among photographers who earn their living taking pictures. However, while professional mirrorless ILCs haven’t eclipsed DSLRs in the marketplace, they’re certainly close to pulling even. They also now represent an attractive option for a broad spectrum of serious shooters.

Moreover, mirrorless cameras have a number of inherent advantages. Most notable is the ability to provide continuous autofocus (AF) before, during and after the exposure. This can be crucial in capturing pro-quality high-speed sequences and 4K video.

Also, eliminating the mirror box enables mirrorless cameras to be smaller and lighter. In addition, their shorter lens-to-sensor distances enhance optical flexibility, allowing optical designers to create smaller, lighter lenses that provide outstanding coverage and imaging performance.

Furthermore, the latest electronic viewfinders (EVFs) in mirrorless ILCs deliver viewing images that compare favorably to the best optical viewfinders. They show changes in camera settings, exposure and white balance in real time; provide continuous live view; and also allow layering of information, including histograms, camera settings, etc.

Freed of the mechanical limitations imposed by a moving mirror, mirrorless cameras also deliver faster shooting speeds; faster AF acquisition; superior focus tracking; silent (electronic) shutter firing; on-sensor phase-detection AF across the entire field; and real-time live view with hybrid AF for advanced AF tracking.

All of these enhancements make it easier to capture pro-caliber stills and video over a wider range of shooting conditions—a huge selling point for pros who have to deliver the goods and are always on the lookout for an edge over their competitors.
