Olympus E-M10 IV vs Samsung HZ30W: A Thorough Hands-On Camera Comparison

In the realm of digital photography, choosing the right camera can be a nuanced decision layered with technical specs, practical use cases, and personal preferences. Having tested thousands of cameras over the years, I’m intimately familiar with how distinct models perform in the field, beyond the glossy spec sheets. Today, we’re putting the Olympus OM-D E-M10 IV, a modern entry-level mirrorless camera launched in 2020, side-by-side with the Samsung HZ30W, a compact superzoom from 2010. Despite their generational and categorical differences, this comparison shines light on who should consider each and why.

Throughout this article, I’ll break down their real-world performance across major photography disciplines, dive deep into technical nuances, and offer recommendations tailored to different users - all while weaving in a comprehensive understanding earned from extensive, hands-on camera evaluations.

Size, Handling, and Ergonomics: When Portability Meets Control

Right out of the gate, the Olympus E-M10 IV asserts itself as a traditional SLR-style mirrorless camera with a thoughtful grip, physical control dials, and weather-sealed bodywork missing here but with excellent build quality. Its dimensions (122x84x49mm) and 383g weight position it as a compact, easily pocketable enthusiast camera.

The Samsung HZ30W, on the other hand, is a compact, fixed-lens superzoom prioritizing portability. Measuring 107x61x28mm and weighing just 245g, it fits comfortably in a jacket pocket or purse - a huge advantage for casual shooters or travelers who value size above all.

Both cameras sport 3-inch LCDs, though their resolutions differ markedly - a subject we’ll explore shortly. Handling-wise, the Olympus’s dedicated exposure compensation dial, shutter priority, aperture priority modes, and a substantial array of customizable buttons and touchscreen input provide tactile feedback and swift adjustments. Conversely, the Samsung’s compact form factors force simplification: a fixed lens, fewer direct controls, and more reliance on automatic modes.

While the Samsung can disappear in your hand or bag and fire quickly, the Olympus delivers a feel and responsiveness closer to professional mirrorless cameras, beneficial for sustained shooting or manual control enthusiasts.

Sensor Size and Image Quality: The Heart of the Matter

Sensor size significantly influences image quality, dynamic range, and noise performance. The Olympus E-M10 IV wields a Micro Four Thirds (MFT) sensor, measuring 17.4x13mm (approximately 226.2 mm²) with a resolution of 20 megapixels. The MFT standard strikes a compelling balance, offering a manageable sensor size while benefiting from an expansive lens ecosystem.

The Samsung HZ30W features a much smaller 1/2.3-inch sensor (6.17x4.55 mm, about 28.07 mm²) with 12 megapixels. This small sensor size significantly limits image quality potential, especially in low light, dynamic range, and color depth, but is typical for compact superzoom cameras designed for portability and convenience.

From my testing experience with similar sensor types, the Olympus’s larger sensor unlocks crisper detail, better ISO tolerance up to ISO 25600 (usable in specific circumstances), and more pleasing, natural color rendering. The Samsung struggles in anything other than bright daylight, yielding noisy images at higher ISOs and softer detail, especially beyond ISO 400.

Moreover, the Olympus benefits from a TruePic VIII processor that enhances noise reduction and color accuracy, whereas the Samsung’s decade-old CCD sensor and lesser processor lag behind in modern image processing pipelines.

Autofocus Performance: Speed and Accuracy When It Counts

Autofocus (AF) systems are the unsung heroes of many successful shots. The Olympus E-M10 IV boasts 121 contrast-detection AF points with an intelligent system supporting face detection, eye autofocus (critical for portraits), continuous AF tracking, and touch AF areas on the tilting touchscreen. These features, combined with a silent electronic shutter offering speeds up to 1/16000s, provide tremendous flexibility for varied shooting environments.

In contrast, the Samsung HZ30W offers a CCD sensor-based AF with contrast detection but lacks face detection or eye AF. It provides center-weighted autofocus with some continuous tracking but cannot compete in speed, especially in low light or fast-moving subject scenarios.

During field tests in wildlife and sports simulations, the Olympus consistently nailed focus acquisition and retention faster and more reliably. The Samsung’s slower AF hunting became evident, underlining its niche as a casual snapshot tool rather than a precision instrument.

Build Quality and Weather Resistance: Ready for the Elements?

Neither camera offers professional-grade environmental sealing or weatherproofing, but there's a subtle difference worth noting.

The Olympus features a robust magnesium alloy construction and arguably better durability given its SLR-mimicking design ethos, even though it’s not explicitly weather sealed. This makes it more suited for outdoor explorations and travel under moderate environmental stress, though heavy rain or dust exposure still requires caution.

The Samsung HZ30W’s typical plastic compact shell lacks durability and offers no protection from elements, aligning with its casual, indoor, or well-controlled outdoor use profile.

Display and Viewfinder: Framing Your Shots

The Olympus sports a 3-inch, 1.04 million dot tilting touchscreen LCD complemented by a high-resolution 2.36 million dot electronic viewfinder (EVF) with 100% coverage and 0.62x magnification. This combo allows flexible composition - eye-level through the EVF in bright sunlight or waist-level with the articulating LCD for creative angles.

Conversely, the Samsung offers a 3-inch fixed LCD with 230k resolution and no viewfinder. The lower screen resolution means the on-camera review appears softer and less detailed, while the absence of an EVF means bright outdoor shooting is challenging, as glare impacts usability. This could be a deal-breaker for those relying on precise framing.

Lens Ecosystem and Optical Zoom: Versatility Versus Specialization

A major Olympus + MFT advantage is the micro four-thirds lens mount and access to over 100 native lenses, ranging from ultra-wide angles to super-telephoto primes and macros. This flexibility empowers photographers to tailor gear around genres and styles - portrait smoothness, landscape resolution, macro detail, and wildlife reach.

In contrast, the Samsung HZ30W comes with a fixed 24-360mm (15x optical zoom) lens at f/3.2–5.8 aperture range. While the long zoom is impressive on paper for a compact at this price point, it trades optical quality and low light performance for reach and convenience. The lens’s fixed aperture narrows light-gathering capability as you zoom, compounding the small sensor’s limitations.

As a result, portably-focused users value the Samsung’s ease of use and zoom range. The Olympus, however, delivers markedly superior glass options for discerning image-makers willing to invest in lenses.

Burst Shooting and Continuous Performance: Catching the Moment

When it comes to action photography, frame rate and buffer capacity matter. Olympus’s 8.7 frames per second (fps) burst rate with continuous AF and exposure tracking makes it capable of sports or wildlife bursts, assuming fast memory cards.

The Samsung, by contrast, does not specify burst shooting capabilities and relies on slower shutter speeds and single-shot autofocus, making it ill-suited for dynamic subjects.

Video Capabilities: Which Camera Shoots Moving Pictures Better?

Olympus E-M10 IV clearly wins here, offering 4K UHD video up to 30p with high bitrates (up to 102 Mbps), delivering sharp, clean footage with a full sensor readout. It also provides various frame rates down to 24p for cinematic looks, plus built-in 5-axis sensor stabilization significantly reduces shake during handheld shooting.

The Samsung supports only 720p HD video at 30 fps and below, encoded in H.264 - modest by modern standards, producing video appropriate for basic casual use, but not serious videography.

Neither camera includes external microphone or headphone ports, limiting sound control. The Olympus’s stabilization and 4K features, however, make it a compelling choice for vloggers and multimedia shooters on a budget.

Battery Life and Storage: Practical Considerations for Long Days Out

Battery endurance is crucial for travel and professional applications. The Olympus E-M10 IV uses the BLS-50 battery rated around 360 shots per charge. In my testing, considering actual shooting conditions (EVF use, LCD time), expect roughly 300-350 shots, which is decent but not class-leading.

The Samsung's battery stats are vague, but similar compact superzooms tend to deliver between 200-300 shots depending on use. It runs on an SLB-11A battery model, with limited capacity considering the era.

Both cameras feature a single card slot supporting SD/SDHC/SDXC storage, with the Olympus supporting faster UHS-II cards, a notable advantage in buffer clearing and video writing speeds.

Connectivity and Additional Features: Modern Conveniences

The Olympus offers built-in Wi-Fi and Bluetooth, enabling remote control, wireless transfer, and tethered shooting with paired devices. This integration fits modern workflows, particularly for travel and event photographers.

The Samsung HZ30W, designed a decade earlier, lacks wireless capabilities entirely, making media transfer limited to USB wired methods.

Real-World Shooting Across Genres: Who Shines Where?

Let’s dissect performance by photographic disciplines to see how these fundamentally different cameras stack up.

Portrait Photography

Olympus’s autofocus face and eye detection, combined with MFT lenses renowned for smooth bokeh (especially primes like the 45mm f/1.8), yield flattering skin tones and sharp eyes with effortless background separation.

The Samsung, by contrast, struggles to isolate subjects optically due to smaller sensor and deeper field depth, generating flatter rendering and limited out-of-focus separation.

Landscape Photography

Dynamic range and resolution dominate landscape outcomes. The Olympus’s 20MP sensor captures a wide tonal range and fine detail, which is further enhanced by RAW file support enabling extensive post-processing.

The Samsung’s lesser sensor size and 12MP resolution, coupled with no RAW capability, translate to reduced ability to recover shadows/highlights, and less detailed images - especially when printing large or cropping.

Wildlife and Sports Photography

Olympus’s fast autofocus, burst rate, and access to super-telephoto MFT lenses provide genuine options for semi-pro wildlife and sports captures, even in challenging light.

Samsung’s slow AF and limited zoom aperture narrow applicability to static or slow subjects in good lighting.
