Olympus E-M10 Mark III vs Olympus VG-120: A Deep Dive into Two Cameras – What Photographers Should Really Know

Choosing the right camera is a highly personal journey, shaped by what and how you want to shoot. Olympus’s offerings across the years have ranged from entry-level mirrorless marvels to compact point-and-shoots, each suited for very different audiences. Today, I’m sharing insights based on extensive hands-on experience comparing two distinct Olympus models: the Olympus OM-D E-M10 Mark III, announced in 2017 as a capable entry-level mirrorless camera, and the Olympus VG-120, a 2011 ultracompact point-and-shoot.

Having personally tested thousands of cameras over the last 15 years, I always look beyond specs and marketing hype. What really matters is how these cameras perform in the field - in low light, in fast-action moments, on a rugged adventure, or just shooting family, landscapes, and everyday life. In this comprehensive comparison, I’ll cover everything from sensor tech, autofocus, ergonomics, to real-world image quality, video capabilities, and more - across all major photography genres. Whether you’re a beginner, traveler, professional, or enthusiast, I aim to help you find which of these two Olympuses best matches your photography aspirations.

A Tale of Two Cameras: Entry-Level Mirrorless vs Ultracompact

Before diving in, it’s important to acknowledge these two aren’t exactly apples-to-apples. The Olympus E-M10 III is an SLR-style mirrorless camera targeting serious beginners or enthusiasts wanting manual control, interchangeable lenses, and solid performance. Meanwhile, the VG-120 is an ultracompact fixed-lens point-and-shoot designed for casual shooters prioritizing portability and simplicity.

The E-M10 III brings a Micro Four Thirds sensor and a sophisticated TruePic VIII processor; the VG-120 relies on a much smaller 1/2.3” CCD sensor and TruePic III processing. Their size and bulk represent a fundamental tradeoff in capability and flexibility. Let’s first look at how they compare physically.

Size and Handling

The E-M10 III (122x84x50mm, 410g) is significantly larger and heavier than the VG-120 (96x57x19mm, 120g). But that added size comes with benefits: solid grip, external controls, and room for sophisticated internals. As someone who relies on steadiness for crisp images, I appreciate the E-M10 III’s ergonomics, especially during extended shoots.

The VG-120 is pocketable and unobtrusive, perfect for grab-and-go shooting and zap shots, but its diminutive size means compromises in comfort, button layout, and stabilization. For street photography or casual travel, its portability is a strong selling point. However, for serious shooting sessions, I found the E-M10 III much more comfortable and confidence-inspiring.

Design and Controls - Making Photography Intuitive

Handling ease and camera interface can make or break your shooting experience. In my tests, layout and responsiveness influenced how often I bothered taking the camera out.

The E-M10 Mark III features a classic DSLR-style design with dedicated dials for exposure compensation, shutter speed, and mode selection. Its tilting touchscreen (3” / 1040k dots) and an electronic viewfinder (2360k dots) allow for flexible, precise composition in various shooting conditions. This mirrors what you’d expect from a camera designed with enthusiast photographers in mind.

By contrast, the VG-120 lacks any form of viewfinder and uses a smaller fixed 3” LCD with only 230k dots resolution, which feels outdated now. Its button layout is minimal; controls are simplified to cater to users unfamiliar with manual settings or those wanting auto-convenience.

In fast-paced contexts like sports or wildlife, the E-M10 III’s tactile controls and responsive autofocus tracking proved superior. The VG-120 is better suited to casual snapshots where complexity is unwelcome.

Sensor Technology and Image Quality - The Heart of the Matter

This section is where these two diverge most substantially. Sensor size and processing power directly influence sharpness, dynamic range, noise control, and color accuracy - crucial for your workflow or final output.

The E-M10 III’s Micro Four Thirds CMOS sensor measures 17.4x13mm, offering a 16MP resolution (4608x3456). The sensor area of 226.2mm² enables better light gathering than smaller sensors, boosting IQ particularly in low light. Olympus’s TruePic VIII processor enhances image clarity, color fidelity, and noise suppression while facilitating 4K video capture.

On the other hand, the VG-120 is equipped with a 1/2.3” (6.17x4.55mm) 14MP CCD sensor (4288x3216), a sensor area of only 28.07mm². Despite respectable megapixels on paper, the tiny sensor severely limits dynamic range and high ISO performance. Images typically display more noise under challenging lighting, less accurate colors, and reduced flexibility in post-processing. The processor, much older TruePic III, can’t compensate fully for these physical constraints.

From my image side-by-side tests, the E-M10 III consistently delivers cleaner, sharper images with richer tonal gradation, especially when shooting landscapes or portraits demanding fine detail and natural skin tones.

LCD Screen and Viewfinder: Composing in the Moment

Composition aids are critical, especially for learning photographers.

The E-M10 III’s 3” tilting touchscreen is a joy to use - bright, responsive, and well-detailed with 1040k dots resolution. It allows shooting from creative angles, such as low ground or overhead perspectives, without exhausting your arms. The built-in EVF proves invaluable in bright daylight where LCDs can wash out. Its 2360k dots resolution offers sharp, lag-free framing.

The VG-120’s fixed 3” TFT LCD proves functional but struggles in bright sunlight and offers no touch controls or tilting flexibility. Without any electronic or optical viewfinder, shooting under harsh conditions can be frustrating.

For street photography or travel, the E-M10 III’s viewfinder and articulating screen provide critical versatility, a boon for composing discreetly or capturing candid moments.

Autofocus Performance - Capturing Fleeting Moments

Autofocus is a key differentiator for workflow and capturing action.

The E-M10 III uses a contrast-detection AF system with 121 points, including face detection and continuous af tracking options. In practice, this translates to fast, reliable focusing - especially for portraits where accurate eye detection preserves sharpness in eyelashes and iris details. For wildlife and sports, the camera’s burst shooting speed of 8.6 fps coupled with stable AF tracking ensures you rarely miss decisive moments.

Conversely, the VG-120 relies on a fixed lens with contrast detection AF, but lacks continuous or face tracking autofocus modes. Its speed and accuracy are sufficient for static subjects but lag during motion. The lack of manual focus or aperture priority options further limits creative control.

For me, shooting fast-moving subjects underscored the E-M10 III’s superiority. Whether capturing a bird in flight or children at play, it delivers the confidence professional or enthusiast photographers seek.

Burst Shooting and Shutter Capabilities

The E-M10 III supports a maximum mechanical shutter speed of 1/4000s, with electronic shutter options reaching 1/16000s - invaluable for bright conditions and creative motion freezing. The camera also supports exposure bracketing and focus bracketing (vital for macro shooters wanting focus stacking, even though this model does not support stacking itself).

The VG-120 caps shutter speed at 1/2000s, with no electronic shutter and no bracketing support, limiting creative flexibility in exposure control and action photography.

Image Stabilization and Flash Performance

The E-M10 III features an outstanding sensor-based 5-axis in-body image stabilization (IBIS), smoothing hand-held shots even at low shutter speeds and enhancing macro or low-light shooting reliability. This alone adds a layer of versatility and value hard to match in its class.

The VG-120 unfortunately lacks any form of image stabilization and depends solely on its flash for low light. While its flash offers up to a 4.4m range, the E-M10 III’s built-in flash and external flash compatibility provide more robust lighting options.

Video Capabilities - Beyond Stills

In today’s multimedia world, video features cannot be overlooked.

The E-M10 III records UHD 4K video at 30fps at a bitrate of 102 Mbps with H.264 codec, plus stereo Linear PCM audio. While no microphone or headphone jacks limit external audio control, the quality far exceeds entry-level expectations, opening doors for hybrid photo/video workflows.

In stark difference, the VG-120 maxes out at 720p HD recording at 30fps in Motion JPEG format, which is outdated and lower quality for contemporary use. Audio capabilities are minimal, no external mic input is available.

If video is a priority, the E-M10 III’s hybrid capabilities are clearly advantageous.

Lens Ecosystem - Crafting Your Vision

The Olympus E-M10 III’s Micro Four Thirds mount supports a vast ecosystem of over 100 native lenses - from fast primes to long telephoto zooms. This flexibility lets you tailor the camera for portraits, macro, wildlife, landscapes, or travel. For example, pairing with Olympus’ excellent 45mm f/1.8 prime produces beautifully smooth bokeh and sharpness, perfect for portraits.

The VG-120 comes with a fixed 26-130mm (equivalent) zoom lens with an aperture ranging from f/2.8 to f/6.5, adequate for casual everyday shooting but with limited control over depth of field or low-light performance.

Battery Life and Storage

In my real-world experience, the E-M10 III delivers approximately 330 shots per charge with its BLS-50 battery, respectable for mirrorless but not astounding. Users planning extended travel should consider spares or a charger. Storage is supported on SD/SDHC/SDXC cards with UHS-I/II speeds, facilitating fast write speeds needed for 4K and burst modes.

The VG-120 lasts about 160 shots per charge with its LI-70B battery and supports basic SD/SDHC cards. Given its limited features, battery longevity is acceptable but once again reflects its casual usage intentions.

Connectivity and Extras

The E-M10 III includes built-in Wi-Fi for remote control and image transfer - a significant workflow accelerator for professionals and enthusiasts alike. No Bluetooth or NFC limits smart connectivity options, but Wi-Fi alone is convenient.

The VG-120 has no wireless connectivity, relying on USB 2.0 for file transfer.

Durability and Build Quality

Neither camera offers weather sealing or rugged protections such as dustproof, shockproof, or freezeproof capabilities. The Olympus E-M10 III feels sturdier and more thoughtfully constructed with a metal chassis imprinting confidence - essential for shooting outdoors in variable conditions.

The VG-120 is primarily plastic, aimed at casual everyday users less concerned with harsh environments.

Price and Value Proposition

At launch, the E-M10 III retailed around $650, reflecting its advanced capabilities. Today, prices may vary but still reflect excellent entry-level mirrorless value.

The VG-120 was priced roughly at $190, targeting users needing simple point-and-shoot functionality at an attractive budget.
