Olympus E-M10 II vs. Olympus TG-630 iHS: A Deep Dive into Two Distinct Cameras for Distinct Users

When Olympus announced the compact, rugged TG-630 iHS back in early 2013 and later introduced the more sophisticated Olympus OM-D E-M10 II in mid-2015, they catered to two very different photography crowds. One is a waterproof travel buddy for the beach and mountain trails, and the other, an entry-level mirrorless camera for the enthusiast craving control, quality, and versatility.

I’ve spent well over a decade testing cameras from all corners of the market - from compact point-and-shoots to wild professional beasts - and compared thousands of real-world shots, autofocus trials, and stress tests. In this detailed head-to-head comparison, I’ll unpack how these two Olympus cameras handle all the major photography disciplines, what their technical strengths and limitations are, and ultimately who will benefit from each model.

Spoiler: These cameras aren’t really competitors in the traditional sense. It’s almost apples and orange juice - but hey, both come from the same fridge, so why not?

First Things First: Size, Handling and Ergonomics

Before diving into specs and pixels, the feel of a camera in hand often dictates your attachment to it. Olympus’s E-M10 II embraces a retro-inspired SLR-style mirrorless body with deliberate dials, comfortable grip, and a solid build that conveys confidence. In contrast, the TG-630 opts for a sleek, compact, button-laden design optimized for adventure and rugged use.

The E-M10 II weighs 390 grams and measures roughly 120mm wide by 83mm tall and 47mm deep. The TG-630 is noticeably smaller and lighter - just 167 grams - with a compact footprint of 98x66x22 mm, making it pocket-friendly and easy to slip into outdoor gear.

Handling the E-M10 II feels like holding a proper camera, with a responsive shutter button, metal dials for shutter speed and exposure compensation, and a thumb grip that actually supports your hand during longer shoots. The TG-630’s compactness sacrifices grip comfort and traditional controls for quick button presses and ruggedness. Its plastic body is tough as nails (more on that in build quality), but the controls are smaller and less tactile, which might frustrate users with larger hands or those who like to change settings on the fly.

For travel or rugged outdoor enthusiasts valuing portability and durability - the TG-630 is clearly the lightweight champ. For those prioritizing a satisfying handling experience and manual control, the E-M10 II wins hands down.

What’s on Top: Control Layout and Design Intuition

Controls shape how quickly and intuitively you can adapt to shooting situations. Olympus’s mirrorless line is often praised for clean, logical layouts, ideal both for learners and experienced shooters.

The E-M10 II’s top panel includes a mode dial with all major exposure modes (P, A, S, M), paired with a dedicated exposure compensation dial. There’s a hot shoe for external flash, a well-placed shutter release, and clearly marked on/off switch - all literally at your fingertips. The metal dials provide precise feedback, which I’ve personally found useful when dragging out a tripod or shooting in cold weather with gloves.

TG-630’s top design is simpler, as expected with point-and-shoots, relying on a mode dial and zoom rocker but lacking any dedicated dials. You won’t find customizable buttons either. For casual shooters or those who prioritize rugged ease over granular adjustments - this setup suffices, and the waterproof sealing means fewer flapping covers.

In essence, E-M10 II is about giving users manual control at their fingertips, while the TG-630 is about quick and straightforward operation with waterproof peace of mind.

The Sensor Wars: Image Quality and Resolution

This is where staple differences begin to show up starkly. The heart of any camera is its sensor, and these two rely on conspicuously different gear reflecting their intended use.

The Olympus E-M10 II sports a 16MP Four Thirds CMOS sensor measuring 17.3x13mm, coupled with Olympus’s TruePic VII processor. This sensor size strikes a balance - larger than typical compacts but smaller than full-frame - offering robust image quality, especially for a mirrorless camera in this price range. Olympus removed the optical low-pass filter to preserve sharpness, and the sensor design delivers a dynamic range of approximately 12.5 EV stops, good color depth (~23 bits), and respectable low-light ISO performance (usable up to ISO 1600–3200 before noise becomes intrusive).

Meanwhile, the TG-630 has a far tinier 12MP 1/2.3” sensor (6.17x4.55mm), typical for advanced compact cameras and rugged waterproof models. This sensor’s smaller area inherently limits image quality, particularly in dynamic range and noise control. Color depth and ISO performance are understandably weaker, and compression artifacts are more noticeable at higher ISOs. Furthermore, the max native ISO caps at 6400, but image quality above ISO 800 rapidly diminishes.

For landscape, portrait, or any scenario requiring good color fidelity and dynamic range - E-M10 II’s sensor will consistently outperform. The TG-630’s small sensor configuration limits it to casual snapshots, where convenience and robustness outweigh image finesse.

See and Compose: The Viewfinder and LCD Experience

Composition tools can dramatically affect your shooting comfort and accuracy. Let’s look at the viewfinder and screen implementations.

The E-M10 II includes a bright 3.0-inch tilting touchscreen LCD with 1.04 million dots, plus an electronic viewfinder (EVF) sporting 2.36 million dots, 100% coverage, and 0.62x magnification. This clarity and magnification enhance manual focusing and fine composition tasks, especially useful in bright outdoor lighting. The touchscreen enables quick autofocus point selection and menu navigation, adding intuitive flexibility.

In contrast, the TG-630 offers a fixed 3-inch LCD panel with a much lower 460k-dot resolution and no touchscreen. There’s no electronic or optical viewfinder - your eyes are glued to the rear LCD to frame shots. While adequate for casual use, the LCD’s limited resolution and lack of tilt or touch make shooting in bright conditions or awkward compositions less friendly.

In my field tests, the E-M10 II’s articulating screen and EVF combo was a huge asset (especially for macro and street shooting), where rapid framing and focus changes count. The TG-630’s screen works as a budget-friendly, rugged solution but with obvious compromises in usability.

Autofocus and Shooting Speed: Tracking the Action

Nothing breaks immersion more than missed focus or laggy burst speeds, no matter camera class. How do these two supersede each other in autofocus performance?

The Olympus E-M10 II employs a hybrid autofocus system focusing on contrast detection with 81 focus points - a high count for this class. It features face detection and continuous autofocus modes, complemented by a 5-axis sensor-based image stabilization system aiding sharper handheld capture. Continuous shooting delivers 8 frames per second with fixed focus, and 3.5 fps continuous AF, which is respectable for enthusiast mirrorless.

In contrast, the TG-630 has a more basic contrast-detection autofocus system with fewer points (not specified officially), face detection but no continuous AF or subject tracking modes. Burst shooting maxes out at about 5 fps but without AF tracking.

In practical tests capturing moving subjects, the E-M10 II consistently locks focus more accurately and quickly, especially in good light. The TG-630 can struggle with moving wildlife or fast sports action, better suited to static snapshots or slow subjects.

Image Stabilization and Low-Light Competence

Olympus is known for its superb in-body image stabilization (IBIS), and the E-M10 II continues that tradition. With sensor-shift 5-axis stabilization, it smooths out camera shake for both stills and video, enabling confident handheld shooting in dim conditions or slower shutter speeds.

The TG-630 has sensor-shift stabilization as well, but with a much simpler system tailored to its small sensor and compact body. It’s sufficient for casual handheld shots, but less effective when shooting video or in near-dark.

Low light is where the E-M10 II’s bigger sensor and IS make a marked difference: ISO 3200 remains usable, and image noise is manageable in RAW with software editing. The TG-630’s sensor hits its noise walls at ISO 800 and above, greatly limiting low-light creative flexibility.

Lens Ecosystem and Optical Performance

This comparison isn’t exactly an apples-to-apples with lenses - because the TG-630 has a fixed lens, while the E-M10 II enjoys Micro Four Thirds (MFT) lens compatibility.

The E-M10 II opens a gateway to over 107 lenses - ranging from bright primes to versatile zooms. You get the freedom to play with bokeh, focal lengths, and specialized optics (macro, tilt-shift, fisheye). MFT lenses are compact and high quality, perfect for travel and enthusiast shooting. This lens ecosystem significantly amplifies the camera’s capabilities and creative freedom.

The TG-630’s fixed 28-140mm equivalent (f/3.9-5.9) lens is a jack-of-all-trades, master of none. It covers useful wide-to-tele zoom but sacrifices maximum aperture for compactness. Macro focus is strong, down to 1cm, excellent for casual close-ups.

If you’re serious about evolving your photography, E-M10 II’s ability to swap lenses is a decisive advantage that the TG-630 cannot touch.

Durability and Weather Resistance

Here’s where the compact TG-630’s rugged personality shines bright.

It’s waterproof to 10m, shockproof from 2.1m falls, freezeproof to -10°C, and crushproof under 100kg of pressure. Meaning, you can use it snorkeling, on hikes with bad weather, or in rugged construction sites without flinching. Battery life is around 220 shots - enough for day trips.

The E-M10 II, meanwhile, is not weather sealed and vulnerable to dust and moisture. Real users must be cautious in rain or dusty outdoors.

So if you’re beaching, mountain biking, skiing, or in environments where cameras tend to get abused - the TG-630’s ruggedness is unparalleled.

Video Playback, Quality, and Features

Video is increasingly important even in stills-centric cameras.

The E-M10 II shoots 1080p up to 60fps, supporting H.264 and Motion JPEG formats, with internal 5-axis stabilization aiding handheld footage smoothness. Though it lacks microphone input or 4K capabilities, video quality beats most entry-level mirrorless models from that era.

The TG-630 records 1080p at 60fps as well but uses MPEG-4 and H.264 with far more limited control or manual video settings. No external audio and no stabilization beyond the built-in lens-shift type. The absence of a microphone jack or touch controls highlights its video limitations.

Overall, E-M10 II wins for creative video projects and quality, while TG-630 suits casual family video memories, particularly when water protection is key.

Battery Life and Storage Options

Battery life for mirrorless cameras often lags behind DSLRs or compacts, but the E-M10 II performs admirably for its class with about 320 shots per charge (CIPA rating). It uses the Olympus BLS-50 battery pack, also common in other OM-D cameras - helpful for users upgrading within the system.

The TG-630, smaller and simpler, offers about 220 shots per charge using the LI-50B battery - a respectable figure despite the camera’s limited feature set.

Both cameras take standard SD/SDHC/SDXC cards but only have single slots, meaning no instant backup options.

If you’re a professional on extended shoots, the E-M10 II’s better capacity and interchangeable battery advantages come into play, while TG-630’s shorter battery life is usually fine for casual or day-trip use.

Connectivity, Wireless Features, and Extras

The E-M10 II packs built-in Wi-Fi, helpful for quick image transfers to smartphones or remote shooting - features photographers increasingly demand. HDMI and USB 2.0 ports allow tethered shooting or external playback.

The TG-630, designed before wireless ubiquity, has no Wi-Fi, Bluetooth, or NFC, though it does feature HDMI and USB 2.0 for direct file transfers.

For serious image sharing and remote control, E-M10 II leads by a wide margin.

Real-World Imaging and Genre-Specific Performance

Let’s get into how these cameras fare across various photographic disciplines.

Portrait Photography

The E-M10 II’s larger sensor, advanced autofocus - including eye detection - and lens options enable exquisitely sharp eyes and creamy, artistic background blur. Colors are true to life, and skin tones natural. TG-630’s small sensor and fixed lens mean flatter, less detailed portraits with sometimes harsh highlights.

Landscape Photography

The E-M10 II offers 16MP resolution and excellent dynamic range, capturing subtle shadows and highlights - ideal for sweeping landscapes. Weather sealing is missing, so cautious use outdoors is required. TG-630’s 12MP sensor and lower dynamic range produce acceptable landscapes but lack fine detail and depth. Its ruggedness is advantageous in harsh terrain.

Wildlife and Sports Photography

E-M10 II’s faster continuous shooting, accurate AF tracking, and lens versatility support wildlife and sports well, especially in daylight. TG-630’s slower AF and burst rates limit action capture. However, the TG-630’s waterproof nature can serve in aquatic environments where mirrorless cameras dare not go.

Street Photography

The E-M10 II with its compact form factor, EVF, and silent shutter modes makes a great street camera for discreet shooting. The TG-630’s compactness is even better for stealth, but lack of EVF and slower responsiveness hinders candid capture.

Macro Photography

E-M10 II’s macro-capable lenses and precise AF allow stunning closeups. TG-630’s 1cm macro focus is impressive for a compact but doesn’t match professional-level sharpness or bokeh isolation.

Night and Astro Photography

E-M10 II shoots cleaner high ISO files and permits longer exposure times with electronic shutter. TG-630’s limited ISO range and higher noise constrain nighttime creativity.

Travel Photography

The TG-630’s toughness, dust and freeze resistance, and small size are perfect for low-maintenance travel amid unpredictable weather. The E-M10 II offers superior image quality and flexibility but requires more care and bulk.

Professional Work

The E-M10 II’s RAW support, robust build (if not weather-sealed), and advanced controls make it capable for pro work as a backup or enthusiast camera. TG-630’s limited manual controls and lower image quality make it inappropriate for professional demands.
