The latest mirrorless, interchangeable-lens cameras provide the complete DSLR shooting experience and more. Their smaller, lighter form factors appeal to a wider variety of consumers, including casual shooters, travelers and women. Indeed, some industry experts have predicted that mirrorless cameras will eventually supplant DSLRs, which are inherently larger, heavier and more complex, for all but high-end professional users.
The technological reasons behind this emerging trend have been significant advances in two key components: the electronic viewfinder (EVF) and the autofocus (AF) system. And while current EVFs may still not equal the “real feel” view provided by the best optical DSLR viewfinders, they have come so far that the differences may no longer be significant to most users.
Today’s best mirrorless models incorporate high-resolution EVFs with incredibly rapid refresh rates that provide a brilliant high-magnification viewing image that rivals that of most optical viewfinders (OVFs). They also have the advantage of allowing users to preview the captured image (complete with exposure corrections and custom settings) in real time. And because of their elevated refresh rates, they provide continuous viewing without “smearing” when viewing fast-moving subjects—the bane of older generation EVFs.
Hybrid AF systems that combine the advantages of fast, decisive on-sensor phase-detection AF and the precision of contrast-detection AF have also taken the autofocus performance of mirrorless cameras to a level surpassing that of most DSLRs. And the advantages of hybrid CAF/PDAF systems also include the ability to provide continuous AF and focus tracking before and during the exposure. This is a crucial factor when shooting still images at high burst rates, or when capturing clean HD video without visible or audible “hunting.”
At their best, mirrorless models combine the advantages of both DSLR and point-and-shoot cameras, providing lens interchangeability, ultrahigh image quality and the entire high-end feature array of middle- and upper-tier DSLRs in smaller, lighter, handier form factors. They have fewer moving parts, and shutter-release noise and vibration are minimal thanks to the elimination of the moving mirror.
Furthermore, they have a shorter flange back distance that’s especially beneficial when designing high-performance wide-angle lenses. And 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. Not surprisingly, as the popularity of the mirrorless models has dramatically increased over the past two years, camera makers and independent lens manufacturers have expanded their lens offerings. This has increased the creative optical options available to consumers as well as marketing opportunities for dealers.
The mirrorless, interchangeable-lens camera market continues to be technologically driven, with many of the latest high-end models offering higher res sensors, faster image processing, faster burst rates, 4K video capture, Wi-Fi connectivity with GPS, multiaxial in-body image stabilization, and enhanced viewing options, such as high-res, tilt/swing and touch-screen LCDs and OLED EVFs.
In fact, entry-level and mid-tier mirrorless models have also benefited from the category’s technological advances. The result is an array of enticing models offering features that have migrated down from higher end models, often with simplified user interfaces—and at competitive prices. It’s like the Great DSLR Evolution all over again, but without the flipping mirror and with the potential of attracting a wider user base.
Here’s a brief rundown on select mirrorless cameras offered by leading manufacturers.
Pentax Q-S1. The elegant contours and leather texture of this aluminum-bodied ultracompact recall the classic rangefinder cameras of the past—but inside the Q-S1 is thoroughly modern. Its 12.4MP, 1/1.7-inch, backlit Pentax-Q-format CMOS sensor (with a 4.6x crop factor) is married to a Q engine image processor. Together they deliver a maximum full-res burst of 5 frames per sec, continuous RAW shooting, Full HD 1080p video recording at 30/24 fps, and a 12,800 maximum ISO setting. Its 3-inch, 460K-dot LCD monitor offers a 170º viewing angle and AR coating. Plus the camera offers built-in shake reduction and a wide array of in-camera effects, including bokeh control, all of which can be previewed in real time.
Other features include: a quick dial for selecting shooting mode; nine smart effects; 11 creative filters; aspect ratio; AF/MF switching; ND filter on/off; auto picture mode selection; interval mode selection; a range of scene modes; built-in HDR; and multi-exposure mode. The Q-S1 supports optional Eyefi and wireless LAN SD memory cards for remote image transfer. A bonus: it is customizable in 40 colors. With 5–15mm f/2.8–4.5 Pentax 02 (27.5–83mm equivalent) lens, $399.95. ricohimaging.com
Sony Alpha a7 II. One of Sony’s a7 high-performance, full-frame, mirrorless models, it is the first to feature sensor-shifting 5-axis SteadyShot Inside image stabilization (IS). The IS system provides a claimed 4.5 stops of compensation for pitch, yaw, horizontal and vertical shift, and roll. This is a big plus when shooting Full HD 1080p video at 60p, 30p and 24p using the high-bit-rate XAVC S format, or shooting handheld stills in low light. The a7II employs a 24.3MP Exmor CMOS sensor paired to a Bionz X processor. Its enhanced “Fast Hybrid” AF system uses 117 phase-detection and 25 contrast-detection sensors on the image sensor, said to provide superior focus tracking and a full-res, 5-fps burst rate with continuous AF and AE.
Other key features include: a 3-inch, 1,228,800-dot tilting LCD monitor; a 0.5-inch, 2.36M-dot XGA OLED EVF; customizable color and gamma controls, including the same S-Log2 Gamma curve found on high-end Sony cinema cameras for increased dynamic range; built-in Wi-Fi with NFC; an ergonomic grip; shutter release and controls; and a magnesium alloy body. With Sony FE 28–70mm f/3.5–5.6 OSS lens, $1,799. sony.com
