Olympus E-M1X vs Sony QX1: A Hands-On Deep Dive for Practical Photographers

When stepping into the camera market, especially with pro mirrorless and novel lens-style systems, it’s easy to get dazzled by spec sheets or gimmicks. I’ve tested thousands of rigs up close - beyond the specs, I look at how cameras perform day-in, day-out in real shooting scenarios. Today, let’s get down to brass tacks comparing two seemingly worlds-apart cameras: the Olympus OM-D E-M1X and the Sony Alpha QX1. The former is Olympus’s powerhouse pro mirrorless flagship released in early 2019, while the latter is Sony’s quirky 2014 lens-style mirrorless with an APS-C sensor designed to clip onto smartphones.

These cameras target hugely different audiences and uses, but comparing them side-by-side illuminates how camera tech and usage philosophies can vary dramatically. Let’s unpack their build, image quality, autofocus systems, usability, and shooting performance across photography disciplines and video. By the end, you’ll know which of these unusual contenders fits your style and budget - or if you should keep searching.

First Impressions: Size, Design, and Ergonomics

A camera’s physical feel inevitably impacts your shooting experience. After countless hours shooting with pro bodies, I can attest that good ergonomics - the clubs for your thumbs and fingers - can make the difference between a good image and a frustrating shutter hold.

The Olympus E-M1X presents as a solid, DSLR-styled mirrorless pro body. It’s chunky at 997g with dimensions of 144x147x75 mm, nearly a kilo - seriously hefty but balanced, built for extended handheld shooting with substantial weather sealing.

Contrast that with the Sony QX1’s featherweight, lens-style form factor at only 216g and just 74x70x53 mm. It looks more like an oversized, fancy lens than a full camera body. It entirely lacks physical controls and must be tethered to a smartphone for operation, making it ultra portable - but unconventional in handling.

So right from the gate, the Olympus screams professional robustness and full manual control, while the Sony is geared toward ultra-light carry and casual, tech-savvy shooters or smartphone photographers wanting to up their image quality.

Top View and Control Layout: Physical vs App-Controlled

Controls are the invisible interface between you and your creative intent. Precision, speed, and tactile feedback all matter.

The Olympus has dedicated dials for shutter speeds, exposure compensation, ISO, AF modes, and a joystick for AF point selection - buttons and wheels are thoughtfully placed for quick thumb or index finger access without diving into menus. It sports dual card slots and a fully articulating 3-inch touchscreen LCD in the back. This body screams “tweak and shoot fast” for pro use.

The QX1, however, has zero physical control buttons, relying entirely on its smartphone app touchscreen interface to adjust settings. This means no tactile feedback or direct manual dials, which might feel limiting or frustrating after extended use - plus, no viewfinder for eye-level composition.

For professionals or even serious enthusiasts, the Olympus’s familiar control layout facilitates fluid operation. Meanwhile, the QX1’s interface might suit casual users or experimenters fine with touchscreen-only interaction.

Sensor Technology and Image Quality

At the heart of every camera is the sensor - a highly technical component that determines resolution, noise performance, dynamic range, and overall image fidelity.

• Olympus E-M1X: 20MP Four Thirds sensor (17.4x13 mm), CMOS with anti-alias filter, maximum ISO 25600, and a variable minimum ISO as low as 64 using boosted modes.
• Sony QX1: 20MP APS-C sensor (23.2x15.4 mm), CMOS with anti-alias filter, max native ISO 16000, and a min ISO 100.

The QX1’s sensor is physically larger by 57% in area, which should, in theory, yield cleaner images, especially in low light and better dynamic range. APS-C sensors have a notable edge when pushing high ISO photography or needing better background separation due to their larger pixels.

The Olympus’s smaller Four Thirds sensor uses a 2.1x crop factor, while Sony’s APS-C swings around 1.6x crop. That impacts lens field of view and depth of field. Olympus relies heavily on software and in-body stabilization to make up for lower light sensitivity.

In real shooting tests, the Olympus delivered tack-sharp images with excellent detail reproduction up to ISO 1600, and usable output to ISO 3200 with strong noise reduction. Its in-body 5-axis image stabilization (IBIS) was a game-changer, allowing slower shutter speeds without blur, especially handy in landscape and macro work.

The Sony has a natural advantage in noise control at higher ISOs (ISO 3200+), thanks to its sensor size, producing cleaner files with better shadow retention. However, it lacks any sensor stabilization, relying on stabilized lenses or tripods.

Display and Electronic Viewfinder: Composing Your Shot

Shooters often overlook how much the viewfinder and screen affect workflow and shooting comfort, but after long sessions, they matter immensely.

The Olympus boasts a 3-inch, fully articulating touchscreen with 1.037 million dots, plus a sharp 2.36 million dot EVF with 0.74x magnification and 100% coverage. The articulating screen is essential for macro, video, or odd-angle shooting. The EVF’s high resolution provides a bright, lag-free live view with accurate real-time exposure preview.

The Sony QX1 lacks any built-in screen or optical/electronic viewfinder; composition and exposure adjustments rely fully on the attached smartphone screen, accessed via Wi-Fi. This setup introduces lag and is less practical outdoors in bright light. While innovative, it presents substantial usability challenges outside controlled environments.

In my experience, Olympus’s viewfinder and articulated screen support a broad range of shooting styles easily and comfortably. The QX1’s dependence on a smartphone display restricts spontaneity and situational awareness.

Autofocus: Speed, Accuracy, and Tracking

Autofocus can make or break your chances of capturing fleeting moments, especially in wildlife, sports, and street photography.

• Olympus E-M1X: 121 focus points, phase-detect and contrast AF hybrid system, face detection, continuous AF tracking, animal eye AF (though absent here), high burst shooting at 60fps (electronic shutter), and focus bracketing/stacking.
• Sony QX1: 25 contrast-detection AF points, no phase-detection autofocus, face detection, single AF only, continuous AF absent, 4fps burst, no focus bracketing or tracking.

The Olympus’s AF system is super fast, precise, and excellent at tracking subjects, suited for fast-moving wildlife and sports. The dual processor (TruePic VIII) engine powers quick calculations, while the hybrid AF covers both phase- and contrast-detect advantages.

The QX1’s AF is sluggish and less reliable for action, limited by solely contrast detection which hunts more and has slower acquisition. Without continuous AF or tracking, you could struggle with moving subjects.

In my field testing, Olympus’s eye detection was spot on, nailing portraits with sharp focus on eyes, while Sony QX1 sometimes missed focus or required frequent manual adjustments.

Build Quality and Weather Sealing

Toughness matters especially for outdoor shooters.

The Olympus E-M1X is a tank, featuring magnesium alloy body, environmental sealing to resist dust and moisture, freeze-proofing down to -10°C, and generally tough construction for demanding pro environments.

The Sony QX1 offers no weather sealing, built with plastic and minimal protection. Its lens-style design compromises ruggedness but maximizes portability.

If your work means braving rough weather or dusty landscapes, Olympus is the clear winner by miles.

Lens Ecosystem and Compatibility

Your lenses often define the system’s ultimate value and utility.

• Olympus: Uses Micro Four Thirds mount with over 107 native lenses available from Olympus and Panasonic covering everything from ultra-wide to super-telephoto, primes to zooms, plus macro. The 2.1x crop factor translates 300mm lens to an effective 600mm reach - ideal for wildlife.
• Sony QX1: Sony E-mount lens-style camera supports any native Sony E-mount lens, meaning a large and varied ecosystem including affordable consumer glass and pro FE primes, but weight and size are considerations as you mount lenses on this clip-on unit. 1.6x crop factor yields tighter framing compared to full frame but less tele reach than Olympus.

The Olympus system is robust, refined, and battle-tested for professional output - video or stills. The Sony's E mount offers broad choice but pairing lenses with the QX1’s unusual form factor can be awkward.

Battery Life and Storage

The Olympus E-M1X features a built-in battery with remarkable CIPA-rated 870 shots per charge under mixed usage, aided by dual TruePic VIII processors efficiency and power-saving functions. It has dual SD card slots allowing overflow or backup recording - a must for pros.

The Sony QX1 uses removable NP-FW50 batteries with a moderate 440 shot rating (per CIPA), half that of the Olympus, reflecting power demands and design priorities. It has a single storage slot supporting microSD cards, more limited and less flexible.

Battery life matters much more when shooting extended sessions or travel - Olympus comes out ahead without question.

Connectivity and Wireless Features

Both cameras offer wireless, but in different fashions:

• Olympus E-M1X: Built-in Wi-Fi, Bluetooth, and integrated GPS for geotagging - great for travel and outdoor photography. Also supports USB-PD charging via USB-C, handy for field power top-ups.
• Sony QX1: Built-in Wi-Fi and NFC for fast smartphone connection but no Bluetooth and no GPS geotagging.

Olympus’s connectivity suite is more complete and professional in flavor, with added convenience of in-camera GPS and better wireless control options.

Video Capabilities

Both cameras possess video functions but cater to different user expectations.

• Olympus shoots 4K UHD (4096x2160) at 24fps, with internal 237 Mbps H.264 using MOV container. It sports 5-axis sensor stabilization (IBIS) for smooth handheld shooting and has microphone and headphone jacks - a boon for videographers wanting quality audio control.

• Sony QX1 is fairly limited to Full HD 1080p at 30fps max, no 4K or external audio input, and no built-in stabilization making handheld video shaky without stabilized lenses or gimbals.

For serious video work, Olympus is the better choice - robust 4K support, solid codecs, and professional audio interfaces.
