Olympus TG-4 vs Sony QX100

Olympus TG-4 vs Sony QX100: Which Compact Camera Fits Your Photography Style?

When diving into the compact camera market, few comparisons spotlight the clear contrast between rugged, adventure-ready cameras and cutting-edge lens-style shooters. The Olympus Tough TG-4 and Sony Cyber-shot DSC-QX100 represent two distinct approaches to compact photography. As someone who has tested thousands of cameras over 15 years - spanning everything from entry-level compacts to professional full-frame systems - I’ve spent considerable time with both these models, exploring their strengths and weaknesses across a broad range of photography genres and technical aspects.

In this in-depth comparison, I’ll unpack everything that matters: sensor technology, autofocus capabilities, build quality, versatility in real-world use, video performance, and more. Whether you’re a rugged outdoor enthusiast or a mobile photography aficionado looking for enhanced image quality, my hands-on insights aim to help you decide which camera aligns best with your creative goals.

First Impressions: Design, Size, and Handling

The Olympus TG-4 and Sony QX100 have fundamentally different body concepts, and understanding their ergonomics is critical from the start.

• The TG-4 sports a traditional compact camera form, with robust physical controls integrated into a waterproof, shockproof, and freezeproof body designed for tough conditions.
• The QX100 lacks a conventional camera body altogether, functioning essentially as a lens-style camera that pairs wirelessly to a smartphone which acts as the viewfinder and control surface.

Looking side-by-side makes this difference clear as day.

At 112mm x 66mm x 31mm and weighing 247g, the TG-4 feels chunky yet comfortable in hand - its textured grip and button layout are built for outdoor use where gloves or wet hands might be involved. The QX100, on the other hand, is much smaller and lighter (63mm cube, 179g), being a lens module without a screen. This minimalist design can be a double-edged sword: it links to your phone for shooting but forfeits a dedicated, always ready ergonomic grip.

In practice: If you want a camera you can pick up, power on, and shoot immediately - even underwater or in harsh environments - the TG-4 shines with its all-in-one resilience and controls. The QX100 will require pairing and handling a smartphone, which adds complexity and may limit spontaneity outdoors.

Examining Controls and Interface

The user interface and control surfaces directly impact how quickly and smoothly you can adjust settings on the fly - essential for professional or enthusiast-level shooting.

The TG-4 features clearly labeled buttons and a dedicated mode dial on top, accommodating aperture priority shooting and exposure compensation via intuitive menus. It supports manual focus and has a physical shutter release that responds confidently, backed by a modest but effective electronic zoom ring.

Conversely, the QX100 sports just a physical zoom ring around the lens barrel, with most settings controlled through its smartphone app. While the app supports touchscreen focus, shutter, and zoom, I found the latency and interface an occasional frustration - especially in low-light or rapid-fire scenarios.

Quick take:

• TG-4: Traditional tactile controls with tactile feedback, suited for deliberate shooting.
• QX100: Sleek, minimalist hardware complemented by smartphone app control, which can feel less immediate.

Sensor Size, Resolution & Image Quality: The Heart of the Matter

Sensor size and technology critically influence image quality, dynamic range, noise performance, and creative control - the foundation of any camera’s photographic prowess.

• Olympus TG-4: Equipped with a 1/2.3-inch BSI-CMOS sensor (6.17mm x 4.55mm) delivering 16MP resolution. While commonplace in rugged compacts, this smaller sensor inherently limits dynamic range and low-light noise performance.
• Sony QX100: Boasts a significantly larger 1-inch BSI-CMOS sensor (13.2mm x 8.8mm) at 20MP, inherited from the flagship Sony RX100 series. This is a key differentiator, offering much cleaner files, superior detail, and greater control over depth of field.

In my lab and field tests, the QX100’s larger sensor consistently outperformed the TG-4 in dynamic range and low-light scenarios. You’ll notice crisper detail retention and smoother tonal gradations, especially at ISO 800 and above. The TG-4’s sensor, while capable in bright light, exhibits more noise creeping into shadows at higher sensitivities.

Pro tip: If image quality, post-processing latitude, and low-light performance heavily influence your purchase, the QX100’s 1-inch sensor generally provides superior results.

Display and Viewfinder: How You Frame Your Shot

Neither camera offers a traditional electronic viewfinder, but their approach to framing and live view differs sharply.

The TG-4 uses a 3-inch fixed LCD screen at 460k-dot resolution - adequate for composing and reviewing shots, but somewhat limited in daylight visibility. The screen is fixed, limiting shooting angles but is engineered for rugged use, including underwater functionality.

The QX100 has no built-in screen; instead, it leverages your phone’s display - which can range widely depending on your device from small 4-inch panels to large, high-res phones with OLED technology. The touchscreen interface of the smartphone app offers focus, exposure, and zoom controls; however, this adds a layer of complexity and dependency on a separate device.

In my tests, the TG-4’s integrated LCD, while modest, ensures independent shooting capability anywhere. The QX100’s reliance on a phone for framing introduces potential lag and battery drain but offers an arguably more flexible and larger display experience when connected.

Autofocus Systems: Speed and Accuracy in Action

Autofocus proficiency often defines a camera’s results, especially in sports, wildlife, or street photography contexts where timing is critical.

• The TG-4 employs a 25-point contrast-detection AF system with face and eye detection, offering continuous AF support at up to 5 FPS. Contrast detection, while reliable indoors and in controlled lighting, can struggle with fast-moving subjects.
• The QX100 relies on contrast-detection with fewer focus points and is primarily operated via manual or tap-to-focus on the connected smartphone’s screen. Continuous autofocus or tracking is not supported.

In the field, I found the TG-4’s autofocus system better suited for action than the QX100’s. The TG-4’s AF was snappier and more consistent with moving subjects like kids or pets. The QX100’s manual focusing or single AF mode is better tailored for deliberate compositions or static subjects.

Build Quality and Environmental Resistance: Weathering the Elements

If you’re shooting outdoors in challenging conditions, build quality and durability are critical.

Without question, the TG-4 is the more rugged, adventure-ready camera. During my outdoor use testing - whether underwater snorkeling shoots or hiking in cold, wet environments - the TG-4 withstood abuse that would damage most compacts. The QX100, lacking any weather sealing, suits more controlled environments.
