Mirrorless Cameras Are Raising the Bar on Technology

Mirrorless Cameras Are Raising the Bar on Technology

The latest models deliver the DSLR shooting experience plus impressive performance in compact packages.


Mirrorless interchangeable-lens cameras are the most vibrant, innovative sector of the camera market. They offer everyone from serious enthusiasts to pros a DSLR-like shooting experience along with significant operational advantages. They also have the greatest upside potential for future development, which is evident in the stunning specs in the models detailed here.

The top models deliver pro-caliber imaging performance in smaller, lighter form factors. And they’re offered at a range of price points commensurate with their feature sets. While traditional DSLRs—which are inherently larger, heavier and more complex—dominate the market in terms of installed user base and unit sales, many experts predict that mirrorless cameras will eventually supplant DSLRs for all but high-end professional users.

This emerging trend is largely based on significant technological advances that are being made in two key mirrorless camera components: the electronic viewfinder (EVF) and the autofocus (AF) system. While current EVFs may still not quite equal the “real feel” view provided by the best optical DSLR viewfinders, the differences won’t be significant to most users. These high-resolution EVFs or OLED EVFs boast incredibly rapid refresh rates and provide a brilliant, high-magnification viewing image. They also have the advantage of allowing users to preview the image captured by the sensor in real time, complete with any exposure corrections and custom settings. This translates to a great advantage when shooting in low light.

Mirrorless cameras also use hybrid AF systems that combine the advantages of fast, decisive on-sensor phase-detection AF and the precision of contrast-detection AF. This has taken the autofocus performance of mirrorless cameras to a level surpassing that of all but pro DSLRs. These AF systems not only provide faster, more accurate AF but also continuous AF and focus tracking before and during the exposure—which is not possible with conventional DSLRs. This is a crucial factor when shooting images at high burst rates or capturing clean 4K and HD video without visible or audible “hunting.”

Top-end mirrorless system cameras also combine the advantages of DSLR and point-and-shoot cameras by offering an enticing combination of lens interchangeability, high-res viewing, ultrahigh image quality and the entire high-end feature array of DSLRs in more portable, handier bodies.

They also have fewer moving parts and less shutter-release noise and vibration thanks to the elimination of the moving mirror. And they provide a shorter flange back distance that makes it easier to design high-performance wide-angle lenses. The shorter lens-to-sensor distance allows users to mount their existing DSLR lenses and a variety of third-party optics, including legacy rangefinder lenses. As the popularity of mirrorless cameras has steadily increased over the past few years, camera makers and independent lens manufacturers have taken notice and expanded their lens offerings, increasing the creative options available to consumers while providing additional marketing opportunities for dealers.

The upside potential of mirrorless cameras is being exploited with amazing technological advances. Many of the high-end models offer high-res sensors; state-of-the-art image processors for greater responsiveness, enhanced AF speed, accuracy and tracking; higher ISO settings; faster burst rates; 4K video capture; Wi-Fi connectivity; GPS; and multiaxial in-body image stabilization. To see where things are going on the technology front, check out the landmark Sony a6300 specs below.

To keep you up to speed on this important category, here’s a rundown on the latest mirrorless compact cameras.

10 Top Mirrorless System Cameras
