The Olympus FE-3010 vs. Sony A7 III: An Expert’s Take on Two Worlds of Photography

Choosing a camera isn’t just about specs on paper or shiny new features - it’s about the kind of photography you want to do and how the camera performs in real-world settings. Today, I’m putting the Olympus FE-3010, a humble ultracompact point-and-shoot from 2009, side-by-side with the Sony A7 III, a 2018 pro-level mirrorless powerhouse. While these two cameras hail from different leagues, comparing them offers insight into how camera technology has evolved and helps you understand what to expect at various price points and user needs.

I’ve spent thousands of hours testing cameras and lenses in studios, wilderness, sporting arenas, and street corners, so buckle up for a detailed, hands-on comparison that’ll go beyond the specs page and dive deep into practical usage, image quality, ergonomics, and value.

Size and Handling: Pocket Portable or Body for the Clubs?

Let’s start with the obvious - the feel in your hands and the physical size.

Olympus FE-3010: This little guy is all about convenience. It’s an ultracompact camera with a tiny 93x56x18 mm chassis weighing just 108 grams. That’s featherlight, pocket-friendly shooting without the bulk. If you just want a grab-and-go camera for casual snaps or vacations and want to slip it into any pocket, the FE-3010 delivers.

Sony A7 III: At 127x96x74 mm and clocking 650 grams, this mirrorless isn’t the pocket rocket, but for a full-frame pro camera, it’s surprisingly ergonomic. The body has deep grips, clubs for your thumbs and fingers, and a solid SLR-style build. It’s designed for all-day wear, even with big lenses attached. The magnesium alloy shell and weather sealing (more on that later) add durability without extra bulk.

Handling-wise, the Olympus is all about minimalism - no clubs for fingers, just a few buttons and menus aimed at straightforward use, perfect for beginners or cheapskates who don’t want to fuss. The Sony’s button layout is professional-grade, with numerous dials for shutter speed, aperture, exposure compensation, and customizable buttons for quick access. It’s quicker to tweak settings mid-action once you learn the controls, especially for sports or wildlife.

My take: If compactness and simplicity are king, Olympus wins here hands down. For people serious about manual control and handling in diverse shooting contexts, the A7 III’s ergonomics and build are worth the heft.

Sensor Technology and Image Quality: The Heart of the Matter

This is where things get very interesting - and the two cameras really part ways.

Olympus FE-3010: Equipped with a modest 1/2.3-inch CCD sensor - about 27.72 mm² - and 12 megapixels, this sensor was standard fare for budget ultracompact cameras a decade ago. CCD sensors typically produce pleasing color but suffer in low light compared to newer CMOS tech. The max native ISO tops out at 1600, with no RAW shooting support and a built-in anti-aliasing filter smoothing fine detail.

Sony A7 III: This full-frame (35.8x23.8 mm) 24-megapixel BSI-CMOS sensor covers a whopping 852.04 mm² - over 30 times larger than the Olympus'. The back-illuminated design improves sensitivity and dynamic range. Native ISO extends from 100 to 51,200 with expansion to 204,800, paired with 5-axis sensor stabilization.

What this means in practice: The Sony’s sensor size alone guarantees far superior image quality - sharper details, richer colors, and excellent noise control at high ISOs. Olympus’s sensor is cramped and limited, suitable primarily for bright light or casual snapshots where image quality isn't critical.

LCD and Viewfinder: Seeing What Counts

Given the cameras’ design targets, it’s no surprise their displays differ vastly.

The Olympus sports a 2.7-inch fixed LCD with 230k pixels, non-touch, and no EVF. It’s serviceable but feels basic and struggles in bright sunlight.

The Sony brings a 3-inch tilting touchscreen LCD with 922k pixels - a much sharper view. It also delivers a 2.36 million-dot electronic viewfinder (EVF) with 100% coverage and a 0.78x magnification, crucial for outdoor precise framing.

In the field, I find the Sony’s EVF and articulated touchscreen invaluable for composing in varying angles and ensuring exact focus, especially with fast-moving subjects or bright sun.

Autofocus and Speed: Chasing the Action

Autofocus (AF) performance is an area where the cameras couldn’t be more different.

• FE-3010: Uses a simple contrast-detect AF system with face detection but no continuous, tracking, or animal eye AF. No manual focus, no burst shooting.

• A7 III: Packs a hybrid AF system with 693 phase-detection points plus contrast detection, 10 fps continuous shooting with AF tracking, plus advanced subject and eye detection for humans and animals - even in video.

In wildlife or sports photography, the difference is night and day. I’ve tested the A7 III chasing birds or soccer players and found its AF blazing accurate and steady. The Olympus is fine for static scenes and casual portraits but falls short once subjects move.

Portrait Photography: Rendering Skin and Expression

Portraiture demands good color rendition, creamy bokeh, and sharp focus on eyes.

Sony:

• Wide lens ecosystem with fast primes (e.g., 85mm f/1.4) for smooth subject isolation.
• Full-frame sensor renders shallow depth of field with beautiful bokeh.
• Reliable eye and face detection AF.
• High color depth (measured 25 bits) and pleasing skin tone reproduction.

Olympus:

• Fixed 36-108mm equivalent zoom lens with max aperture f/3.1-5.9 - limited background blur capability.
• Face detection present but less reliable.
• Smaller sensor limits detail and tonality.

In my portraits, the Sony recreates skin tones with natural warmth and fine gradation, delivering punchy subject separation. Olympus portraits come across flatter with limited background separation and less refined color.

Landscape Photography: Detail and Dynamic Range

Sony’s 14.7 EV dynamic range and 24MP detail outclass the 12MP Olympus with limited dynamic range on a small sensor.

I took both cameras on a foggy morning shoot:

• The Olympus struggles with HDR highlights and shadows, losing detail in skies or foliage.
• The Sony’s sensor and 16-bit RAW files capture impressive gradations and allow extensive exposure latitude.

Weather sealing exists on both but is minimal - neither waterproof, though Olympus claims some environmental sealing.

Wildlife and Sports: Speed and Reach

Olympus offers a 3x zoom (36-108mm), not ideal for distant wildlife. Its 10.8x zoom multiplier is misleading compared to full-frame.

Sony, with access to everything from 70-200mm f/2.8 to 600mm super telephotos in the E-mount system, thrives for wildlife and sports.

Burst speed (10 fps) and AF tracking knock the Olympus flat in terms of action shooting.

Street and Travel Photography: Discretion and Versatility

Olympus’s pocketable size favors street shooters who want to keep things low profile - though its image quality and AF limitations may frustrate serious shooters.

Sony’s bigger dimensions are less discreet but bring versatility with lenses and high ISO capabilities essential for variable lighting on the go.

Battery life difference is stark: Olympus specs poorly documented, but likely limited. Sony’s NP-FZ100 easily delivers over 600 shots per charge.

Macro and Close-Ups

The Olympus macro focusing down to 5cm means you can get decent close-ups for casual shots, but limiting in lens speed and lack of focus stacking feature.

Sony’s ecosystem offers dedicated macro lenses with exceptional sharpness and precision focusing, better suited for demanding macro work.

Night and Astro Photography

The Sony’s high ISO capability (native to 51,200, expandable) combined with sensor stabilization make it a solid option for night and low-light photography, including astrophotography.

Olympus’s CCD sensor struggles with noise and detail retention in dim environments, limiting night capabilities.

Video Capabilities

Olympus: 640x480 video at 30 fps in Motion JPEG - useful for casual snippets but obsolete by today’s standards.

Sony A7 III: Supports UHD 4K at 30p, Full HD at up to 120 fps for slow motion, advanced codecs, microphone and headphone jacks for audio monitoring, and in-camera 5-axis stabilization for smooth handheld footage.

For videographers, no contest - the Sony is a serious tool.

Build Quality and Weather Resistance

Both cameras lack waterproofing or robust dust-proofing.

Sony benefits from more durable magnesium alloy chassis, weather sealing suitable for rain and dust. Olympus has some environmental sealing but is more vulnerable.

Lens Ecosystem and Compatibility

Olympus FE-3010’s fixed lens is a limiting factor for creative flexibility.

Sony’s E-mount system offers over 120 native lenses from ultra-wide to super-telephoto and many third-party options.

Connectivity and Storage Options

• Olympus relies on USB 2.0 and uses xD-Picture Cards and microSD - obsolete and severely limited in capacity and speed.

• Sony provides USB 3.1, dual SD card slots, Wi-Fi, Bluetooth, NFC, and HDMI out.

Battery Life and Storage Media

Sony’s battery life is excellent for a mirrorless camera (~610 shots/charge), supporting longer shooting sessions. The Olympus likely fares poorly by comparison.
