Olympus E-M10 vs Sony H55: Which Camera Fits Your Photography Style?

Choosing a camera can be a rewarding but complex journey, especially when options come from two very different corners of the market. Today, I'm diving deep into the Olympus OM-D E-M10 - an entry-level mirrorless champion released in 2014 - and the Sony Cyber-shot DSC-H55 - a small sensor compact from 2010. Both cameras come with distinct personalities, capabilities, and price tags, but which one truly deserves a place in your bag?

Throughout this article, I’ll share insights from my extensive hands-on testing experience with these cameras, touching on all major photography fields - portraits, landscapes, wildlife, sports, street, macro, night, video, travel, and professional work. Along the way, you’ll find image comparisons, technical analyses, and practical recommendations grounded in real-world use. Let’s get into it.

Physical Build and Handling: Ergonomics That Matter

Before even clicking a shutter, the camera’s physicality plays a major role in your overall experience. I always stress the importance of handling because a camera that’s comfortable encourages more shooting, better framing, and ultimately more satisfying results.

The Olympus E-M10 sports a classic SLR-style mirrorless body typical of the OM-D line. Its compact design balances portability with control, yielding a relatively lightweight 396 grams in a 119x82x46 mm frame. The Sony H55, true to its compact category, weighs 200 grams and measures 103x58x29 mm - noticeably smaller and slimmer.

Ergonomically, the E-M10 feels solid and substantial in hand thanks to its grip, customizable mechanical dials, and well-placed buttons. Its tilting 3-inch touchscreen (with 1037k dots) complements the electronic viewfinder (EVF) boasting a sharp 1440k dot resolution and 100% coverage - an increasingly rare feature in entry-level cameras. The Sony H55’s body leans toward pocketability, emphasizing convenience over tactile control. Its fixed 3-inch LCD only has a 230k dots resolution and no EVF, which may limit precision framing in bright conditions.

If you value manual dials, customizable buttons, and a confident grip for longer sessions, the Olympus is your winner here. But if you mostly crave portability and ease of grab-and-go shooting, the Sony’s compact footprint and lighter weight will appeal.

Sensor and Image Quality: The Heart of the Matter

One of the most critical aspects for any serious photographer is sensor technology and what it means for image quality. I always take sensor size, resolution, and technology into account to quantify IQ performance before judging real-world results.

Let’s look at the specs visually:

The Olympus E-M10 employs a 16MP Four Thirds CMOS sensor measuring 17.3x13 mm, which is significantly larger than the Sony H55’s 14MP 1/2.3-inch CCD sensor sized 6.17x4.55 mm. Larger sensors generally provide better dynamic range, color depth, and low-light performance.

Backed by Olympus’s TruePic VII image processor, the E-M10 boasts excellent color fidelity and noise control. Its tested DxOMark scores - 72 overall, 22.8 color depth, and 12.3 EV dynamic range - underscore its solid image quality credentials. Conversely, the Sony’s sensor, while versatile for its compact class, is not DxOMark tested and inherently limited by its small area, yielding noisier performance and narrower dynamic range, especially in challenging lighting.

In practical shooting, the E-M10’s native ISO range of 200–25600 (with usable studio quality up to ISO 1600–3200) delivered clean files with excellent detail retention. The Sony shoots from ISO 80 to 3200 but luminous noise creeps in past ISO 400. The difference is immediately noticeable in shadows and highlights.

In terms of resolution, both cameras deliver images around 16MP, yielding prints up to 16x20 inches comfortably. However, Olympus’s sensor architecture and lens sharpness often translate into crisper landscapes and portraits.

In sum: for photographers prioritizing superior image quality - especially in low light and for large print work - the Olympus E-M10 is a decisive choice. The Sony H55 suits casual snapshots and travel shots under ample daylight.

Art of Seeing: Viewfinder and Screen Experience

Clear and responsive framing tools can make or break a day in the field. The Olympus’s inclusion of a bright, sharp EVF with 0.58x magnification and 100% coverage gives photographers a real edge for precise composition, especially in bright sun or when using manual focus.

Its 3” tilting touchscreen LCD with touch-to-focus and menu navigation adds significant flexibility for shooting at tricky angles. Given that touchscreens are almost standard in modern cameras, the E-M10’s interface feels modern and responsive.

On the other hand, the Sony H55 misses out on a viewfinder altogether and sports a 3” fixed LCD at a comparatively low resolution, limiting usability in strong outdoor light and manual shooting modes. No touchscreen either.

Here’s the visual difference in interface:

For anyone shooting street, candid, or sports photography, the clear viewfinder is a non-negotiable. The E-M10 effortlessly wins this matchup in tools for critical focusing and framing.

Autofocus: Chasing the Moment

Autofocus systems can be an invisible hero or a source of frustration depending on how well they handle your preferred subjects. I’ve done extensive AF testing - focusing speed, accuracy, tracking, and low light performance - to compare mirrorless and compact systems.

The Olympus E-M10 features contrast-detection autofocus, supplemented with 81 focus points and face detection. Although it lacks phase-detection AF (common in newer mirrorless models), it performs admirably in good light. In my tests, continuous AF tracking of moving subjects was fairly reliable for street photography and casual wildlife shooting, but it hit limits for fast sports action.

Sony’s H55 offers a much simpler AF system with just 9 points, all contrast-detection, without face or eye-detection. It’s fine for static scenes and daylight snaps, but chasing fast-moving subjects proved quite challenging. Accuracy dropped noticeably indoors or in dim conditions.

In a nutshell, if you anticipate shooting wildlife or sports requiring fast, accurate autofocus tracking, or portraiture that benefits from eye/face detection, Olympus’s system has the clear edge.

Lens Ecosystem and Flexibility

Lens choice is fundamental when deciding on a camera system. The Olympus E-M10 uses the Micro Four Thirds mount, arguably one of the richest lens ecosystems available, with over 100 native lenses from Olympus, Panasonic, and third parties covering everything from ultra-wide to pro-level telephotos, macros, fisheyes, and fast primes.

Sony H55’s fixed lens (25-250mm equivalent, f/3.5-5.5) provides 10x zoom versatility but no option to swap lenses. This design favors simplicity but limits creative scope and image quality potential since it’s constrained by the fixed zoom lens optics.

If you love experimenting with focal lengths, prime lenses for portraits, or specialized lenses for macro & landscapes, the Olympus system’s flexibility wins hands-down. The H55 is better if you prefer an all-in-one solution requiring minimal fuss or investment.

Burst Shooting and Shutter Speed: Catching the Action

Olympus E-M10 offers an 8 fps continuous shooting rate, respectable for its class, plus a maximum shutter speed of 1/4000 sec. The Sony provides a faster burst at 10 fps but caps shutter speed at only 1/1600 sec.

While the Sony’s burst seems tempting, I found its buffer depth and autofocus during continuous shooting less dependable. Olympus’s 8 fps with AF tracking is more balanced for overall action sequences.

For sports or wildlife enthusiasts requiring dependable burst capture and fast shutter options for freezing motion, the Olympus is more versatile.

Video Capabilities: Moving Images Matter Too

In the age of multimedia, video performance is no afterthought.

Olympus E-M10 records full HD 1080p video at 30 fps with H.264 codec, sensor-based image stabilization, and offers time-lapse recording. No microphone or headphone jacks limit professional sound control, but video image quality is solid for casual filmmaking.

Sony H55 shoots HD 720p video - lower resolution - with MPEG-4 format but lacks image stabilization for video and offers no external mic input either.

For vloggers or hybrid photographers looking to capture crisp Full HD footage with stabilization, Olympus is the stronger candidate. The Sony suits casual video capture only.

Battery Life and Storage

Battery life is often overlooked but critical when you’re out shooting for hours.

Olympus’s BLS-5 battery delivers approximately 320 shots per charge - modest but average for mirrorless cameras. The Sony H55 uses the NP-BG1 battery but interestingly doesn’t specify battery life; from experience, compact cameras like this tend to underperform compared to interchangeable-lens systems.

Both use SD card slots, but Sony’s supports multiple card formats (Memory Stick Duo / Pro Duo / PRO HG-Duo, SD/SDHC) increasing storage flexibility.

Connectivity: Sharing Made Simple?

Wireless connectivity is increasingly important for rapid image sharing or remote shooting.

Olympus E-M10 includes built-in Wi-Fi (no Bluetooth or NFC) – allowing you to transfer images and control the camera via smartphone apps. Sony H55, reflecting its 2010 origins, offers no wireless options.

For seamless social media sharing or remote operation, Olympus again leads this generation gap.

Durability and Weather Sealing

Neither camera boasts environmental sealing, waterproofing, or advanced durability features. Both require care in harsh environments.

Pricing and Value Analysis

Originally launched at around $600, the Olympus E-M10 now can be found at discounted rates, typically between $350-$450 lightly used. The Sony H55, being older and compact, often sells new or used at sub-$250 price points.

For roughly double the price, the Olympus offers distinct advantages in image quality, versatility, and usability. Still, budget buyers or those prioritizing simplicity may find Sony’s lower entry cost hard to overlook.

How They Perform Across Photography Genres

To synthesize these findings, I scored and ranked both cameras across distinct photographic disciplines based on hands-on experience and metric analysis:
