Let’s dig in.

First Impressions: Size, Feel, and Handling

Before picking up either camera, it’s clear from their specifications and design intent that the Olympus E-M1 II and the Sony TX7 inhabit very different worlds - one is a pro-level mirrorless system camera, and the other a compact point-and-shoot.

Olympus E-M1 II: Robust and Purpose-Built

The Olympus E-M1 II is a solid, SLR-style mirrorless camera weighing 574 grams, with physical dimensions of 134 x 91 x 67 mm. Its size and heft immediately communicate durability and serious intent, strongly appealing to advanced photographers. The camera features a well-designed grip and an articulate, fully articulated touchscreen LCD, lending itself well to versatile shooting angles.

Sony TX7: Pocket-Friendly and Unobtrusive

In stark contrast, the Sony TX7 is an ultra-compact camera, hardly weighing 149 grams and measuring a mere 98 x 60 x 18 mm. It slips effortlessly into a pocket, perfect for grab-and-go city shoots or travel where minimalism is key. The flat design and fixed lens mean the camera won’t attract any undue attention, ideal for discreet street photography.

In-hand, the Olympus feels substantial and reassuring, suited for long shooting sessions, while the Sony’s petite form factor feels liberating when minimal gear is a priority. However, this compactness naturally limits controls and customization.

Personal Tip: I always suggest shooting with both in person if possible. The Olympus' extensive controls require finger familiarity, whereas the Sony’s simplicity shines for quick, casual snaps.

Design Language and Control Layout

Ergonomics can make or break your experience, especially under pressure or on extended outings.

The Olympus E-M1 II sports a professional-grade control scheme: multiple customizable dials, dedicated buttons for ISO, white balance, drive mode, and more. This layout enables rapid manual adjustments without diving into menus - essential for sports, wildlife, and fast-paced shooting.

The Sony TX7, constrained by its compact form, instead embraces minimal physical controls and emphasizes touchscreen operation. There’s no electronic viewfinder; you rely on the rear fixed 3.5-inch screen (though it’s bright and clear) to compose your shots.

From my testing experience: The Olympus is great for photographers who relish tactile control and precision, while the Sony suits those who prefer simple operation and point-and-shoot ease.

Sensors and Image Quality: Size Matters

No camera comparison is complete without analyzing sensor technology, arguably the heart of any digital camera. Here, the Olympus E-M1 II and Sony TX7 diverge significantly.

Olympus E-M1 II’s Four Thirds Sensor

The Olympus features a 20MP Four Thirds sensor measuring 17.4 x 13 mm, with a sensor area of 226.2 mm². While smaller than APS-C and full-frame, this sensor balances resolution, speed, and lens compactness. Olympus removed the anti-aliasing (AA) filter to boost sharpness, making images crisp and detailed. Its ISO sensitivity spans 200-25600 (expandable to 64), with DxOMark scores confirming solid dynamic range (~12.8 EV) and color depth (~23.7 bits).

Sony TX7’s 1/2.4” Sensor

The Sony TX7 packs a much smaller 10MP BSI-CMOS sensor, measuring only 6.1 x 4.6 mm (27.9 mm²). This-sized sensor inherently limits dynamic range, low-light performance, and overall image quality, but it’s typical for ultra-compact cameras. The maximum native ISO caps at 3200, though noise becomes quite apparent beyond ISO 800.

In real-world use, the Olympus consistently delivers more nuanced color rendition, lower noise at higher ISOs, and a more forgiving dynamic range. The Sony’s images suffice for casual snapshots and web sharing but won’t hold up as well for printing or professional work.

Visual Interfaces: LCD and Viewfinder

The Olympus E-M1 II incorporates a bright 3-inch, 1037k-dot fully articulated touchscreen and a high-resolution electronic viewfinder (EVF) boasting 2.36 million dots, 100% coverage, and 0.74x magnification. This combination serves photographers well, allowing flexibility in composing at various angles, including low and overhead shots, with precise framing and focus confirmation via the EVF.

The Sony TX7 uses a larger but fixed 3.5-inch touchscreen LCD with a decent 921k-dot resolution. However, it lacks any form of viewfinder - optical or electronic. This is typical of compact cameras and generally acceptable given the TX7’s casual use case, but bright sunlight can challenge LCD visibility.

Having personally used similar setups for night markets and street photography, I found the Olympus display and EVF invaluable when lighting conditions worsened or I wanted to stabilize the camera against my face. The Sony’s fixed screen, while bright, requires more care with glare reflections.

Autofocus and Performance: Speed and Accuracy

For action photography, wildlife, or sports, autofocus (AF) system capabilities can make a decisive difference.

Olympus E-M1 II: A Pro AF Beast

The Olympus boasts a hybrid AF system with 121 phase-detection points plus contrast detection, face detection, and touch AF. Predictive tracking and continuous autofocus perform exceptionally well in fast-moving scenarios. In burst mode, the E-M1 II can shoot up to 60fps electronically, making it one of the fastest mirrorless cameras of its time.

Sony TX7: Basic Contrast AF and Limited Speed

By comparison, the Sony uses a contrast-detection AF with only 9 focus points and no continuous AF tracking. Burst shooting maxes out at 10fps, slower and less responsive compared to the Olympus. No face or eye detection is available, which limits snap accuracy in dynamic situations.

My field tests confirmed: the Olympus autofocus is superb for wildlife and sports, locking swiftly and tracking erratically moving subjects accurately. The Sony works best for still subjects and static scenes.

Lens Ecosystem and Versatility

One massive advantage of the Olympus system is its Micro Four Thirds (MFT) lens mount, compatible with an astonishing selection of over 100 lenses from Olympus, Panasonic, and third parties. Whether you want ultra-wide landscapes, macro close-ups, fast primes for portraits, or super-tele zooms for wildlife, MFT has you covered.

The Sony TX7 has a fixed 25-100mm equivalent (4x optical zoom) lens with a maximum aperture of f/3.5-4.6. It’s versatile enough for casual day-to-day shooting and close-up macro (down to 1cm), but the optical quality and aperture range are limited compared to interchangeable lenses.

For me, lens flexibility can be a key reason professionals choose mirrorless systems like the Olympus, while the Sony appeals to those prioritizing compactness and convenience with a fixed zoom.

Build Quality and Weather Resistance

The Olympus E-M1 II excels in build quality, featuring durable magnesium alloy construction and comprehensive environmental sealing against dust and moisture. While not waterproof, it stands up well in challenging conditions - a big plus for outdoor landscape or wildlife shooters who brave the elements.

The Sony TX7, designed as an ultra-compact consumer camera, lacks any weather sealing or ruggedness features. Its plastics and build materials are adequate for gentle, everyday use but not for harsh environments.

Battery Life and Storage

The Olympus E-M1 II uses a BLH-1 battery, rated for approximately 350 shots per charge under CIPA standards, which aligns with typical mirrorless system performance. Dual SD card slots offer secure and flexible storage options - great for professionals shooting large volumes or wanting backups.

In contrast, the Sony TX7 uses a smaller NP-BN1 battery, with battery life generally shorter due to compact design but unspecified in CIPA terms for this model. It has one storage slot supporting Memory Stick Duo/Pro Duo and optionally SD cards.

Video Capabilities: Quality and Features

Olympus offers strong video specs with 4K UHD (3840x2160) up to 30fps and DCI 4K (4096x2160) at 24fps, recording in MOV H.264 format with high bitrates (up to 237 Mbps for DCI 4K). The camera provides microphone and headphone jacks for full audio control. While it lacks in-body image stabilization during video, its sensor-based 5-axis stabilization helps smooth handheld shooting.

The Sony TX7, constrained by its compact hardware, offers 1080p full HD video at 60fps in AVCHD format. There is no microphone or headphone input, and lens-based optical stabilization is available during video capture.

For videographers, the Olympus serves as a more serious hybrid still/video tool, while the Sony covers basic home movies or casual clips.

Specialized Photography Disciplines

Portraits

The Olympus shines for portraits with its accurate eye-detection AF, rendering of skin tones, and fast primes delivering creamy bokeh thanks to its lens ecosystem. The Sony’s fixed zoom and limited aperture restrict bokeh quality and control, and it lacks eye AF.
