Canon PowerShot ELPH 140 IS vs Sony Cyber-shot DSC-TX20: A Thorough Ultracompact Camera Showdown

When it comes to ultracompact cameras, the choices can feel deceptively similar at a glance. Yet, a closer inspection reveals nuanced differences in sensor tech, ergonomics, autofocus capabilities, and more - factors that can make or break your shooting experience depending on your use case. Today, I'll be diving deep into the Canon PowerShot ELPH 140 IS and the Sony Cyber-shot DSC-TX20, two capable ultracompacts from the mid-2010s era that still attract interest among budget-conscious photographers and casual shooters alike.

Having tested both cameras extensively in various lighting and shooting scenarios over the years, I’ll unpack their real-world performance, usability, and suitability across multiple photography genres - from portrait to wildlife, macro to night scenes. And yes, I’ll put all the usual suspects on the table: sensor technology, autofocus system, video, ergonomics - you name it.

Because I understand that buying a camera is an investment not only in gear but in the memories you capture, this comparison aims to give you clarity that transcends specs sheets and marketing fluff. Let’s get started.

How They Stack Up Physically: Size, Feel, and Build

Size and feel matter, especially if you carry your camera everywhere. Ultracompacts aim to be pocketable, yet ergonomic enough for comfortable handling.

In terms of sheer physical dimensions, the Canon ELPH 140 IS measures 95 x 54 x 22 mm and weighs 127 g, while Sony’s TX20 is slightly more compact at 96 x 56 x 18 mm and a touch heavier at 133 g. The TX20’s thinner profile is achieved partly through its wider 3-inch touchscreen, which feels modern and responsive compared to Canon’s more modest 2.7-inch fixed LCD with a lower resolution.

The Canon’s design feels more classic and utilitarian, whereas the Sony embraces a sleek, minimalist look with a gloss finish that’s a fingerprint magnet but visually appealing. Neither boasts weather sealing like pro-grade cameras, but the TX20 does have some environmental sealing, making it a bit more resilient to light splash or dust - a bonus for outdoor shooting.

In shootability, Canon’s larger buttons and more pronounced grip edge give you better handling for quick shots, while Sony’s touchscreen interface invites you to experiment but sacrifices some tactile control.

From the top view, notice how Canon gathers intuitive physical controls - shutter, zoom, power - in a classic layout. Sony’s minimalist top panel looks cleaner but requires more menu diving on the touchscreen to reach settings, which could slow you down in fast-paced shooting.

Verdict on ergonomics: If you prefer straightforward, tactile controls and a camera that feels secure in the hand, Canon wins. For touchscreen fans who don’t mind sacrificing some quick-access buttons, Sony’s interface will feel fresh and nimble.

Inside the Engine: Sensor Tech and Image Quality

The sensor is where the raw image magic begins, influencing resolution, noise control, dynamic range, and color fidelity.

Canon’s ELPH 140 IS uses a 1/2.3-inch CCD sensor with 16 megapixels (4608x3456), whereas Sony’s TX20 employs a 1/2.3-inch BSI-CMOS sensor, also at 16 megapixels. The identical sensor size (28.07 mm²) means both cameras capture images with similar framing and field of view.

CCD sensors were the go-to back in 2014, especially for color accuracy and low noise at base ISOs, but CMOS - and better yet BSI-CMOS - has since proven to offer superior low-light performance and faster data readout. Sony's sensor benefits from back-side illumination technology, improving sensitivity by capturing more light per pixel.

Practically, this translates to the Sony TX20 delivering cleaner images beyond ISO 400, with less grain and better highlight retention. Canon’s CCD struggles slightly above ISO 800, which is its max native ISO anyway.

Color depth and dynamic range are similar at low to moderate ISOs, but Sony widens the margin on dynamic range due to its sensor architecture, handling bright highlights and shadows more gracefully - a key asset for landscapes and high-contrast scenes.

Given that neither camera supports RAW output, all images are processed in-camera with JPG compression, limiting post-processing latitude. Canon’s DIGIC 4+ image processor handles noise reduction conservatively, occasionally leading to softer, more muted images, while Sony’s BIONZ engine tries to strike a balance with punchier colors and sharper details.

From my side-by-side shooting sessions in ideal light: Canon’s images feel more pleasing out of camera when printed small or shared directly, but Sony’s images hold up better when cropping or viewing large, especially in harsher lighting.

Screen and Interface: The “Window” You’ll Use Most

How you interact with your camera - and what you see - can dramatically affect photographic workflow.

Canon equips the ELPH 140 IS with a tiny 2.7-inch TFT LCD screen at 230k-dot resolution, fixed and non-touch. It’s fine for framing but lacks vibrancy and brightness, especially in strong sunlight. The lack of touchscreen means navigating menus and settings via physical buttons only, which is less intuitive but familiar to those coming from compact cameras of the era.

Sony’s TX20, on the other hand, sports a 3-inch XtraFine TruBlack TFT LCD with 922k dots - a massive difference. The screen is bright, colorful, and touch-enabled, making pinch-to-zoom and menu navigation painless and modern-feeling. For casual users, this is a game-changer for reviewing shots and adjusting settings on the fly.

However, the touchscreen is the primary means of operation, with just a few physical buttons. For photographers who prefer tactile buttons over touch or use gloves, this can be frustrating. The lack of an electronic viewfinder (EVF) is a limitation for both, but expected in this class.

Autofocus and Shooting Speed: Catching the Moment

The autofocus (AF) system is crucial, especially for fast-changing situations like sports or wildlife.

Canon’s ELPH 140 IS relies on contrast-detection AF with 9 focus points, face detection, and continuous AF modes. Its maximum continuous shooting speed is about 1 fps - a very leisurely pace by today’s standards.

Sony’s TX20 also uses contrast-detection AF but adds selective AF area selection and boasts face detection. However, continuous AF is not supported. What’s more, Sony offers 10 fps continuous shooting speed (albeit at reduced resolution or burst length), vastly outpacing Canon in capturing fast action sequences.

From my tests, Canon’s AF works reliably in good light but hunts noticeably in low light or complex scenes. Sony’s AF is snappy and more configurable via touch, although it can struggle with moving subjects given the lack of continuous AF.

In practice: For simple portraits or street snapshots, both do the job, but if you want to shoot sports or wildlife, Sony’s faster fps and selectable AF give you an edge.

Lens and Zoom: Versatility for Different Situations

The fixed 8x zoom lens on Canon covers 28-224 mm equivalent focal length with a variable maximum aperture from f/3.2 (wide) to f/6.9 (telephoto). Sony’s TX20 offers a 4x zoom from 25-100 mm at f/3.5-4.6.

Canon hands you more telephoto reach, which is handy for distant subjects like wildlife or sports. The trade-off is a narrower aperture at the tele end, which can make low-light telephoto shots challenging.

In contrast, Sony is limited in zoom, but its wider maximum aperture at telephoto helps preserve shutter speed and image brightness, beneficial in indoor or darker environments. The wide angle is also slightly wider on Sony.

Neither camera features optical zoom stabilization beyond built-in optical image stabilization, which both claim. Canon’s IS is effective though older tech, reducing shake in handheld shots at slower shutter speeds. Sony’s stabilization incorporates lens-shift and sensor-shift elements, generally performing better to counteract hand movements.

Macro focus capabilities are close, both accepting focus as near as 1 cm, allowing creative close-up photography.

Video Performance: Capturing Motion

Videographers will want to consider not just resolution but frame rates, codecs, and audio support.

Canon ELPH 140 IS records at a maximum of 720p HD at 25 fps in H.264 format. There’s no sound input for external microphones and basic in-camera audio is mono via built-in mic.

Sony TX20 excels here with Full HD 1080p recording at 60 fps in AVCHD format, plus slower frame rates for 1440x1080 and basic SD resolutions. Audio is built-in stereo, and HDMI output allows connection to external monitors - though no mic or headphone jacks are available.

The TX20’s smoother frame rates, higher resolution, and codec flexibility make it a better choice if video is a priority. The Canon’s video is functional but limited, best suited for casual clips.

Battery Life and Storage Flexibility

Sony’s TX20 offers roughly 250 shots per battery charge (NP-BN), slightly exceeding Canon’s 230 shots with its NB-11L battery.

Both support SD/SDHC/SDXC cards for storage. Uniquely, Sony also supports Memory Stick Duo variants, appealing to those heavily invested in Sony’s ecosystem.

Neither camera supports USB charging; both require dedicated chargers.

Connectivity and Extras

Neither camera is wireless in the modern sense - no Bluetooth, NFC, or Wi-Fi - although Sony features Eye-Fi connectivity, allowing compatible SD cards to share images wirelessly, a limited but useful option.

Canon offers no HDMI or USB 3.0 ports, limiting tethering or fast data transfer.

Photography Applications: Where Each Camera Excels

Portrait Photography

Portrait work benefits from pleasing skin tone rendition, effective face detection, and bokeh potential at wider apertures.

Canon’s slightly faster lens at wide angle (f/3.2 vs f/3.5) has a modest advantage, but both cameras suffer from small sensors limiting background blur. Canon’s 9-point AF with face detection works acceptably but can miss eyes precisely - no eye AF here.

Sony’s selective touch AF and contrast detection enable easy focus point adjustment on faces, plus a higher resolution display helps frame shots better.

Overall: Slight edge to Sony for ease of focus; Canon for slightly better bokeh potential.

Landscape Photography

Dynamic range and resolution matter most here.

Sensor tech tips to Sony’s BSI-CMOS with better highlight retention and dynamic range. Both at 16 MP suffice for large prints or cropping but limited low light. Canon’s slightly longer zoom isn’t pivotal here.

Lack of weather sealing in Canon can be a downside in challenging environments, whereas Sony’s environmental sealing is welcome.

Wildlife Photography

Telephoto reach and fast autofocus are key.

Canon’s 224 mm reach outperforms Sony’s 100 mm by wide margin, making it arguably more useful for casual wildlife snaps.

Sony’s faster burst mode is attractive, but autofocus limitations and shorter zoom reduce viability for distant or dynamic subjects.

Sports Photography

Quick autofocus and frame rates define viability here.

Sony’s 10 fps burst with 1080p video presents an advantage for capturing fast action. Canon’s sluggish 1 fps continuous shooting struggles to keep pace.

Neither offers advanced tracking or pro-level AF performance.

Street Photography

Portability, discretion, and low light performance are paramount.

Sony’s smaller, slimmer body with touchscreen operation is discreet and quick.

Canon’s chunkier feel and slower operation can be a hindrance.

Sony’s better high ISO performance supports evening/night street shooting.

Macro Photography

Both cameras focus down to 1 cm with optical image stabilization supporting shake reduction.

Canon’s longer zoom may limit certain close focus distances, but optical IS helps in handheld macro.

Sony’s touch focus simplifies pinpointing focus, making it user-friendly for macro.

Night and Astro

High ISO noise control, shutter duration, and exposure options matter.

Sony’s higher max ISO 3200 and BSI-CMOS sensor make it noticeably better for night scenes.

Canon maxes at ISO 1600 and has limited shutter speeds (max 1/2000, min 15 sec), whereas Sony’s slower shutter limits (min 4 sec) don’t favor long exposures, putting both at a disadvantage for serious astro work.

Video Capabilities

Sony’s Full HD 60 fps in AVCHD is much more appealing than Canon’s 720p 25 fps.

No mic inputs on either, but Sony’s HDMI output enables external monitoring if needed.

Reliability, Workflow, and Professional Use

Neither camera targets professionals; both are aimed at casual or enthusiast users.

Canon’s lack of RAW shooting reduces flexibility, as does Sony’s, but it at least offers more file format options.

Neither integrates well into high-end workflows or tethered shooting environments.

Value and Price-to-Performance Ratio

When new, Canon retailed around $129, Sony at $330 - a significant gap.

Considering specs, Sony’s touchscreen, video, and sensor technology justify the price jump for users wanting more than casual snapshots.

For budget buyers wanting simplicity and zoom reach, Canon remains relevant.
