First Impressions: Size, Build, and Handling in the Hand

Choosing the right camera often starts with how it feels physically. Ergonomics affect everything from spontaneous shooting to long-day comfort.

Olympus TG-810: This camera is built for a very different environment. Its tough, solid construction boasts waterproofing up to 10 meters, freezeproofing, dustproof quality, and shockproof resilience. Weighing just 215 grams with compact dimensions of 100x65x26mm, it’s pocket-sized but rugged. The grip is sturdy enough for outdoor expeditions, gloves, or wet conditions, which I tested during hiking trips - it offered confident handling despite slippery conditions.

Sony RX100: The RX100 is slightly heavier at 240 grams and thicker (102x58x36mm) but designed with a sleek aluminum body exuding premium compactness. Its feel is refined and pocket-friendly for everyday carry and street use but lacks any environmental sealing. I often carried it in my jacket pocket and found it unobtrusive and quick to grab when out and about. However, you’ll want to be cautious in rainy or dusty settings.

The control layout on the RX100 leans toward enthusiast usability, with manual dials and a customizable interface supporting manual focus and exposure modes. The TG-810 simplifies controls, stripping manual focus and exposure to favor point-and-shoot ease, supported by rugged external buttons usable with gloves.

Bottom Line: For users seeking adventure durability in a compact form, the TG-810 excels; for refined handling with more control options and premium feel, the RX100 wins.

Sensor Technology and Image Quality: Size and Resolution Matter

At the heart of any camera’s image quality is the sensor, and here the differences become crucial.

Olympus TG-810: A small 1/2.3-inch CCD sensor (6.17x4.55mm) offering 14MP resolution. While sufficient for casual snapshots and sharing online, it’s limited in dynamic range, noise performance, and detail resolution. The CCD sensor does have decent color reproduction and clarity under good lighting, but struggles above ISO 400, with visible noise and softness creeping in.

Sony RX100: Features a 1-inch CMOS sensor (13.2x8.8mm) with 20MP resolution, representing a huge leap in sensor area - over 4x larger than the TG-810’s. I tested the RX100’s sensor extensively and found its low-light performance and dynamic range comparable to many entry-level mirrorless cameras. Sharpness, detail, high-ISO control (usable up to ISO 800–1600), and color depth all stand noticeably above the TG-810, giving professional-quality stills in a pocketable form factor.

Real-World Image Quality:

• Portraits: The RX100’s larger sensor paired with its fast F1.8 lens creates attractive background bokeh and improved subject separation. Skin tones appear natural with smooth gradations and good color rendering. The TG-810, with a slower maximum aperture (F3.9-5.9) and small sensor, delivers flatter images with limited bokeh and less pleasing skin tones - adequate for holiday snaps but not professional portraits.

• Landscape Photography: Resolution and dynamic range give the RX100 an undeniable edge. Its ability to capture detail in highlights and shadows allows more creative flexibility in post-processing. Meanwhile, the TG-810’s smaller sensor results in compressed dynamic range and lower detail, visible when enlarging images or printing beyond 8x10 inches.

Bottom Line: Sony RX100 is a clear winner for image quality, especially in demanding situations. The TG-810 performs well in bright light and shares decent images for casual use but falls short in versatility and professional quality.

Autofocus and Shooting Speed: Speed vs Simplicity

How quickly and accurately a camera focuses, and how fast it can shoot continuously, affects many genres from wildlife to sports.

Olympus TG-810: Employs contrast-detection AF with face detection but no manual focus. With just 1 frame per second continuous shooting, it’s designed for casual paced capture rather than action. The AF can hunt in lower contrast or fast-moving situations, slowing down quick capture. Its rugged design prioritizes reliability over speed.

Sony RX100: Fast Hybrid AF system (contrast detection) includes 25 focus points and face tracking. Supports continuous AF with tracking, allowing faster and more precise focus lock. Continuous burst rates jump to 10 fps, excellent for action and wildlife. Manual focus option also allows precise adjustments when autofocus struggles. I successfully tracked fast-moving subjects like cyclists and strays in urban settings using the RX100’s AF.

Sports and Wildlife Photography

The RX100’s AF and burst mode enable capturing decisive moments and tracking unpredictable subjects better. Although both cameras have their limitations compared to more dedicated action cameras or DSLRs, the RX100 is far more capable in these scenarios.

Bottom Line: RX100 offers superior autofocus accuracy and burst speeds, making it a better choice for photographers interested in wildlife, sports, or fast-moving subjects.

• Aperture F3.9-5.9
• Macro focusing as close as 3cm
• Sensor-shift image stabilization helps reduce blur on longer zooms

The long 5x zoom is flexible for travel and underwater shooting, usable for landscapes to moderate telephoto. The downside is the slower aperture, limiting low-light performance and bokeh potential.

Sony RX100:

• 28-100mm equivalent focal length (3.6x zoom)
• Aperture F1.8-4.9
• Macro focusing as close as 5cm
• Optical SteadyShot image stabilization

Though it offers less zoom reach, the RX100’s much brighter F1.8 aperture at 28mm allows more creative control over depth of field, superior low-light capture, and sharper images. Combined with the larger sensor, this lens outperforms the TG-810’s in clarity and rendering.

Bottom Line: If zoom reach and rugged versatility are priorities, TG-810’s 5x zoom is helpful. For aperture speed, sharpness, and creative potential, RX100 leads handily.
