Nikon Coolpix L31 vs Sony Cyber-shot DSC-TX66: An Ultracompact Camera Face-off for Real-World Photography
Choosing between compact cameras can be tricky these days. Despite the smartphone boom, dedicated ultracompact cameras still hold appeal for photographers craving better zoom, handling, or specific features that phones can’t quite match. Today, I’m diving deep into a detailed comparison between two popular ultracompacts from different eras and philosophies - the Nikon Coolpix L31 and the Sony Cyber-shot DSC-TX66. Both boast 5x zoom lenses in similar focal ranges, but their approach to image capture and handling differ quite substantially.
Having tested thousands of cameras over 15 years, I’ve been looking at everything from sensor tech, autofocus, real-world performance across genres, ergonomics, to value for money. If you’re a photography enthusiast or a professional scouting a secondary travel or low-commitment camera, this hands-on comparison will help clarify which of these cameras deserves your attention.
Size, Handling & Design: Pocketability vs Grip Comfort
Both the Nikon L31 and Sony TX66 belong firmly in the ultracompact segment - but that doesn't mean they share the same handling experience.
The Nikon L31 is chunkier at 96 x 59 x 29 mm and weighs about 160 grams, powered by two AA batteries. This design, while not pocketable in a tight jeans pocket, offers a relatively secure grip with more tactile buttons. If you value having something substantial in your hand, especially for casual shooting, the L31 feels reassuring.
In contrast, the Sony TX66 is a slim beauty at just 93 x 54 x 13 mm, weighing a featherlight 109 grams with a rechargeable battery pack. At about half the thickness, its sleek design easily slips into most pockets - ideal for street photographers or travelers who prize discretion and lightness.
Looking closer, controls on the L31 feel basic - there’s no touchscreen, no manual focus, or exposure control. Sony takes a more modern approach with a touchscreen-enabled OLED display (more on that shortly) and basic manual focus control. That said, familiar physical buttons on Nikon might suit those who dislike touch or want a more straightforward experience.
The bottom line: if pocketable size is a priority, Sony wins. If you want a bit of heft and a classic camera feel, Nikon’s larger body is compelling.
Sensor Technologies & Image Quality: 16MP CMOS vs 18MP BSI-CMOS
In the digital photography world, sensor quality often trumps megapixels for image excellence. Both cameras share the same sensor size - typical 1/2.3" at approximately 28 mm² area. However, the Sony TX66 employs a more modern Backside Illuminated CMOS (BSI-CMOS) sensor versus Nikon L31’s traditional CMOS sensor.
Why does this matter? BSI sensors improve light gathering efficiency, especially in darker parts of the scene or low-light conditions, which translates to cleaner, less noisy images.
Sony leads with slightly higher resolution at 18MP compared to Nikon’s 16MP, and its maximum ISO sensitivity reaches a very impressive 12800 (compared to Nikon’s modest 1600). Of course, real-world usability at very high ISOs is limited on these small sensors, but it hints at better noise management in the Sony.
Practical testing confirms Sony’s advantage in shadow details and low-light shots; colours are more vibrant and preserved with more dynamic range. The Nikon delivers decent daylight images but shows early noise onset past ISO 400.
Viewing Experience: OLED Touchscreen vs Fixed LCD
Now, the screen can make or break your shooting enjoyment, especially with no viewfinders on either model.
The Nikon’s 2.7-inch fixed LCD with just 230k dots resolution is serviceable but frankly quite underwhelming in 2024 standards. It feels grainy, struggles under bright outdoor light, and offers no touch interaction.
Sony’s 3.3-inch XtraFine TruBlack OLED touchscreen with 1230k-dot resolution is a remarkable upgrade. The deep blacks, vivid colours, and touch-to-focus/shoot capability make framing and reviewing images enjoyable. Adjusting settings is simpler with the touchscreen, reducing menu diving.
For instant visual feedback, Sony’s screen gives serious points. Nikon’s screen is usable but can become frustrating when fine composition or review is needed.
Autofocus and Usability: Basic Contrast Detection vs Touch-Enhanced Tracking
Autofocus on ultracompacts can be a wildcard. The Nikon L31 uses single autofocus based on contrast detection with a center-weighted AF point and supports face detection but lacks tracking or continuous autofocus. There’s no manual focus or focus area selection. In practice, the L31's AF locks reasonably fast in good light but struggles in low contrast or dim situations.
The Sony TX66 ups the game with touch autofocus, face detection, and importantly, tracking autofocus despite similar hardware autofocus tech. The ability to tap on-screen to set focus combined with tracking helps keep moving subjects sharp - useful in street or casual action scenarios.
In real-world trials, Sony’s focusing felt noticeably more agile and accurate in challenging light or with busy subjects. Nikon’s slower AF can produce missed shots, especially in complex scenes.
Zoom Lens Performance: Same Focal Length Range, Different Aperture Trade-offs
Both cameras offer an equivalent 26-130mm zoom lens with a 5x optical zoom range, appropriate for everyday shooting from wide-angle landscape to modest telephoto portraits.
However, aperture differs:
- Nikon L31: F3.2 at wide, F6.5 at telephoto
- Sony TX66: F3.5 at wide, F4.8 at telephoto
Sony’s lens is optically stabilized with Optical Image Stabilization (OIS), whereas Nikon uses digital image stabilization. Optical stabilization tends to provide sharper shots at slower shutter speeds, essential for telephoto or low light.
When testing both at full zoom, Sony’s images were visibly sharper with less motion blur - a testament to OIS’s benefit. Nikon’s digital stabilization can soften images especially in dimmer light or when zoomed in.
The Sony’s smaller minimum macro focusing distance (1 cm vs Nikon’s 10 cm) is a neat bonus for close-up work, making it better suited for casual macro photography.
Burst Shooting and Shutter Speeds: Fast and Flexible vs Basic
Regarding continuous shooting, Nikon does not provide continuous burst mode - the shoot pace is limited to one shot at a time.
Sony offers 10 fps continuous shooting (single AF only), which is exceptional for a compact camera and useful for capturing fleeting moments - sports fans and wildlife spotters will notice this advantage.
Shutter speed ranges also differ: Nikon’s max shutter is 1/2000s, while Sony offers 1/4000s on the fast end and a longer 30-second slow speed available for night or creative low-light shots.
The flexible shutter on Sony contributes nicely to creative control, even if manual exposure modes are absent on both cameras.
Video Capabilities: HD at 30fps vs Full HD at 60fps
Video specs also reveal the age gap and market approach differences.
Nikon L31 shoots basic 720p HD at 30fps in Motion JPEG format - a codec known for large files and lower compression efficiency. No microphone input or advanced video features.
Sony TX66 records in Full HD (1920 x 1080) at 60fps, offering smooth footage in AVCHD or MPEG-4 formats, which are more professional and versatile. There’s an HDMI output but no microphone jack.
While neither camera targets serious videographers, Sony’s specs give it a clear edge for casual yet sharp and smooth video shooting.
Battery Life and Storage: AA vs Proprietary Packs
Battery types can affect travel convenience and long shooting sessions.
Nikon L31 uses readily available 2x AA batteries, rated for approximately 200 shots. Advantage: you can carry spares easily and replace batteries on the road without chargers. Drawback: AA batteries add weight, and alkaline cells drain rapidly; rechargeable NiMH AAs improve cost and sustainability.
Sony TX66 depends on a proprietary rechargeable NP-BN battery pack delivering roughly 250 shots per charge. This is standard in ultracompacts but means you must carry chargers or spare batteries to extend shooting days.
Storage-wise, Nikon supports SD, SDHC, SDXC, while Sony uses Memory Stick and microSD cards - Sony's memory stick formats can complicate card choice and swapping for some users.
Connectivity and Extra Features: Minimal Wireless, Basic Timers, and No Weather Sealing
Neither camera supports wireless connectivity (Wi-Fi, Bluetooth, NFC), a bit of a limitation for instant sharing.
Both have self-timers (Nikon 10 seconds; Sony 2 or 10 seconds with panorama assist). Nikon lacks features like white balance bracketing present in Sony, and only Sony offers spot metering.
Neither camera is weather-sealed, splash-proof, or ruggedized, so both require cautious handling outdoors.
Real-World Photography Tests Across Genres
Taking a hands-on approach, here’s where these two stand in key photography scenarios:
Portrait Photography
- Sony’s wider aperture at tele makes better background blur, and its superior face detection + touch AF makes focusing on eyes easier.
- Nikon produces decent skin tones, though slight softness and digital stabilization can reduce sharpness.
- For casual portraits, Sony’s sharper images and HD video help create memorable moments.
Landscape Photography
- Both capture decent wide-angle from 26mm equivalent.
- The higher-res Sony sensor renders landscapes with finer detail; dynamic range is modest for these sensors but Sony’s BSI sensor helps shadows more.
