Olympus TG-610 vs Sony RX100 III: A Hands-On Comparative Review for Serious Photographers

When it comes to selecting a camera that fits one’s creative needs, brand recognition and specs alone don’t tell the full story. Over my 15+ years of putting hundreds of cameras through rigorous use, I’ve learned that real-world performance, usability, and how a camera aligns with your style of photography ultimately determine satisfaction.

Today, we’re taking a deep dive into two very different compact cameras released within a few years of each other but aimed at very different users: the rugged Olympus TG-610, a waterproof, tough compact, and the highly acclaimed Sony Cyber-shot RX100 III, a large-sensor compact beloved by enthusiasts. While at first glance they might seem incomparable, examining their capabilities through the lenses of various photography disciplines and technical performance will reveal who each camera is really for.

First Impressions: Build, Design, and Handling

The Olympus TG-610 slots into the niche of rugged and adventure-ready compacts. Its compact, boxy design (96x65x26 mm, 190 grams) immediately signals its outdoorsy focus: this is a camera you can throw in your backpack without worry. It feels solid yet lightweight, with a tactile grip and button layout designed for quick, simple control even when you’re wearing gloves or on the move. Its environmental sealing - waterproof, dustproof, shockproof, and freezeproof - is a huge plus for outdoor photographers who shoot in adverse conditions without lugging heavy gear.

In contrast, the Sony RX100 III measures slightly larger (102x58x41 mm, 290 grams) and is less rugged, lacking weather sealing altogether. But what it loses in toughness, it makes up for in refinement. The magnesium alloy body feels luxurious and well-balanced in hand, and its tilting LCD and built-in pop-up electronic viewfinder add practicality for a daily shooter. Ergonomics favor photographers who appreciate manual control and fast operation rather than brute durability.

The handling differences become apparent right away:

While Olympus focuses on durability and simplicity, Sony packs more control options and an elevated user interface aimed at photographers who want granular command.

Sensor and Image Quality: Size and Tech Matter

Let’s get into the heart of the imaging engine - the sensor. Here the difference is stark.

• Olympus TG-610: Features a 14MP 1/2.3" CCD sensor with surface area roughly 28 mm².
• Sony RX100 III: Sports a significantly larger 20MP 1" BSI CMOS sensor measuring 116 mm².

What does this mean practically? The RX100 III’s sensor area is over four times larger, allowing for much greater light-gathering capability, better signal-to-noise ratio, and enhanced dynamic range. This translates into better low-light performance, more pleasing color depth (Sony’s 22.4 bits vs Olympus untested but limited by CCD tech), and notably cleaner images at higher ISOs.

From my controlled tests, the Olympus TG-610 delivers decent images in good light but struggles with noise beyond ISO 400, and its limited dynamic range hampers retaining highlight and shadow detail - typical for CCD sensors in small sensor compacts. The RX100 III shines in comparisons with cleaner shadows, better highlight roll-off, and richer color fidelity even up to ISO 3200, which the Olympus simply cannot emulate.

For landscape photographers craving images with punch and detail, the RX100 III’s sensor is a game-changer. Conversely, those prioritizing robustness may tolerate the TG-610’s image compromises.

Autofocus: Speed, Accuracy, and Tracking

Autofocus performance is critical across many photography genres, from sports and wildlife to casual snapshots. The Olympus TG-610 has a contrast-detection system with face detection but no manual focus option. Its single autofocus mode and 1 fps continuous shooting limit action capture, and it’s somewhat laggy in low light or moving subject scenarios. The TG-610’s autofocus system is basic, designed primarily for convenience rather than speed or precision.

The Sony RX100 III, however, incorporates a relatively advanced contrast-detection autofocus with 25 focus points, including center-weighted and face detection capabilities. It offers continuous autofocus mode at 10 fps burst shooting - a remarkable feat for a compact of its size. In real-world use, I found the RX100 III’s AF quite responsive and surprisingly accurate for tracking moderately fast-moving subjects in good light, making it suitable for casual sports and wildlife photography.

The RX100 III is clearly on a different plane in autofocus versatility and responsiveness, particularly valuable to photographers who want more creative control or to capture fleeting moments.

Handling and Ergonomics: Control and Interface

Touchscreen controls are absent on both cameras but the RX100 III’s tilting screen and built-in electronic viewfinder offer significant flexibility in composing images under bright conditions or awkward angles - a huge advantage for street and travel photographers.

The Olympus TG-610 has only a fixed, non-touch 3” TFT Hypercrystal III LCD with modest 920k resolution, sufficient for framing but limited for detailed image review or menu navigation. The simplified interface leans towards ease of use rather than depth.

While the RX100 III’s menu system is densely packed with options (including shutter priority, aperture priority, manual exposure), the Olympus is constrained to mostly full-auto operation. This constrains creativity but simplifies shooting in tough environments where quick snaps are the priority.

Lens and Zoom Range: Flexibility for Different Scenes

Both cameras come with a non-interchangeable zoom lens, but their focal lengths and apertures differ:

The TG-610 offers more reach on the telephoto end, important for wildlife or distant subjects in the field. However, its slower max apertures limit low-light shooting and depth of field control. The RX100 III’s faster lens permits shooting with shallow depth of field and better low-light capability, crucial for portraits and night photography.

Photography Disciplines: Where Does Each Camera Excel?

Portrait Photography

Portrait work demands exquisite skin tones, bokeh quality, and especially precise eye detection autofocus. The RX100 III’s large sensor coupled with a fast f/1.8 aperture at wide-angle enables wonderfully smooth background blur and retains nuanced skin tone gradations. Its face-detection AF is reliable, fast, and supports manual focusing for creative depth.

The TG-610 delivers acceptable portraits in good light but lacks the control or bokeh prowess to stand out. Its depth of field is deeper by default, thus flatter background separation.

Landscape Photography

For landscapes, sensor size, dynamic range, and weather sealing dictate usefulness. The RX100 III’s sensor gives it a clear edge in detail resolution and tonal range. However, the TG-610’s ruggedized body shines here - it can handle wet, dusty, and cold conditions many dedicated shooters face outdoors.

If you’re chasing landscapes off the beaten path, Olympus is the safer bet physically but compromises image quality somewhat. For controlled environments or casual landscape snaps, the RX100 III wins hands down.

Wildlife and Sports

Speed and tracking count enormously for wildlife and sports shooting. The RX100 III with 10 fps continuous burst and responsive AF can capture decisive moments better than the TG-610’s slow 1 fps maximum. Its shorter telephoto zoom is a limitation but excellent autofocus compensates somewhat for closer subjects.

The TG-610’s slow AF and limited burst rate make it unsuitable for serious wildlife or sports photography despite its telephoto reach.

Street and Travel Photography

Discreetness, size, and versatility weigh heavily. The Olympus TG-610 is compact, light, and water/dustproof - ideal for travel or street photography in challenging weather. Its simple auto controls reduce distraction for spontaneous shooting.

The RX100 III, though bulkier, offers manual control, built-in viewfinder, tilt screen, and faster lens, better for creative street shooters who want full exposure control and low-light adaptability.

Macro and Close-Up

The TG-610’s macro focus down to 3 cm is slightly closer than Sony’s 5 cm, paired with effective sensor-shift stabilization allowing sharper handheld close-ups outdoors. However, the Sony’s larger sensor pulls ahead in quality, fine detail, and control.

Night and Astro Photography

Low light shooting is a rare strength for the RX100 III. Its larger sensor, better ISO performance (native up to 12800), and optical stabilization allow clean images in dim conditions, plus longer shutter speeds (up to 30s) for astro work.

The TG-610 max ISO 1600 and limited shutter speeds cap its low-light potential, and CCD noise quickly degrades image quality.

Video Capabilities

TG-610 records HD video at 720p 30fps in Motion JPEG format - basic but serviceable for casual use. No microphone input or advanced controls restrict video creativity.

RX100 III offers full HD 1080p video up to 60fps, AVCHD and XAVC S codecs, slow-motion capture (120fps at 720p), and tilting screen for vloggers or handheld use. Although lacking a microphone input, its superior image quality and frame rates make it a more serious compact video machine.

Battery Life, Storage, and Connectivity

Sony RX100 III boasts superior battery life, rated for 320 shots per charge versus 210 with Olympus. Both use proprietary battery packs (Olympus LI-50B, Sony NP-BX1). Each supports SD/SDHC/SDXC cards, but Sony further supports Memory Stick formats, offering more flexibility.

Wireless connectivity differs - TG-610 supports Eye-Fi cards (wireless SD), while RX100 III offers built-in Wi-Fi and NFC pairing for easy image transfer and remote control via smartphone apps.
