Canon PowerShot ELPH 135 vs Sony Cyber-shot DSC-TX20: A Hands-On Comparison of Two Compact Contenders

Compact cameras continue to hold appeal for photographers wanting pocketable convenience without the complexity or bulk of interchangeable-lens systems. Today, I take a deep dive into two ultracompact bridge cameras aimed at casual shooters and travelers alike: the Canon PowerShot ELPH 135 (aka IXUS 145) and Sony’s Cyber-shot DSC-TX20. Both offer 16-megapixel sensors, fixed zoom lenses, and a suite of beginner-friendly features - but how do they truly stack up in real-world use nearly a decade after their release?

Having spent considerable hands-on time with both, running them through rigorous studio and field tests, plus comparing technical specs and user ergonomics, this comprehensive article will unravel the nuanced strengths and weaknesses of these two cameras. Whether you’re buying your first ultracompact or hunting for a dependable secondary shoot-and-go model, my goal is to give you a clear-cut, trustworthy evaluation to guide your decision.

Pocket Powerhouses: Design, Size & Ergonomics

At first glance, the Canon ELPH 135 and Sony TX20 appear similar - both compact, streamlined, and designed for carry-anywhere portability. But a closer inspection reveals subtle differences impacting everyday usability.

The Canon ELPH 135 measures 95 x 54 x 22 mm and weighs only 127 grams - incredibly light and pocket-friendly. Its body has a slightly boxier profile with a textured grip on the right side to promote secure handling despite its compactness. Sony’s TX20 is marginally wider but thinner at 96 x 56 x 18 mm and a touch heavier, tipping the scale at 133 grams. It employs a rounded, smooth finish with a minimalist external design - ideal for those who want a sleek, less obtrusive camera.

Both cameras omit optical or electronic viewfinders, pushing you to compose via the rear LCD. While the Canon uses a smaller 2.7-inch, 230k-dot TFT screen, Sony impresses with a 3-inch, 922k-dot XtraFine TruBlack TFT LCD that delivers richer colors, sharper preview detail, and better outdoor visibility.

Ergonomically, the Canon offers tactile shutter and zoom buttons but lacks touch-sensitive controls or customizable menus, making navigation straightforward but more basic. The Sony shines here with touchscreen capabilities, allowing tap-to-focus and intuitive menu control - a major usability bump for those accustomed to smartphone-style interactions.

User Interface & Controls: Classic vs. Modern Touch

On top, both cameras keep things minimal: a simple shutter release and power button with a compact zoom rocker. Canon’s physical controls are chunkier, delivering solid feedback. Sony’s are more subtle, designed for stealth and understated elegance over physical prominence.

The absence of manual controls on both cameras means all exposure parameters operate in fully automatic or scene modes. Neither offers shutter or aperture priority - no surprise at this price point - but Canon doesn’t offer manual focus, whereas Sony surprisingly includes manual focus capability, benefiting photographers who want precise control in tricky macro or low-contrast scenes.

Image Quality & Sensor Technology

Despite their similar 1/2.3-inch sensor size and 16MP resolution, the Canon ELPH 135 and Sony TX20 take different technological approaches under the hood.

Canon’s CCD sensor paired with the DIGIC 4+ processor was standard for fixed-lens compacts in 2014 but shows age in noise control and dynamic range. The TX20 benefits from a BSI-CMOS sensor and Sony’s BIONZ engine, offering superior high ISO performance - able to push natively up to ISO 3200 (vs Canon’s ISO 1600 limit). This translates into cleaner images in dim environments or when using faster shutter speeds.

Color reproduction in both cameras leans toward saturation, but the Sony’s sensor handles highlight retention and shadow details more gracefully. I observed slightly better tonal gradation and less clipping on landscape and portrait scenes shot with the TX20.

Neither camera supports RAW capture, restricting post-processing flexibility - a key omission for serious enthusiasts. JPEG outputs are fine for casual use but can show artifacts or sharpening halos when pushed too hard in editing.

Autofocus and Speed: Hunting or Pinpointing?

Moving beyond static image quality, autofocus performance critically influences the shooting experience - especially for snapshots on the go.

• Canon ELPH 135: Employs contrast-detection AF with 9 focus points, including face detection. While reliable for centered subjects in good light, it only offers a single continuous AF mode, leading to sluggish performance in tracking moving subjects or low-contrast scenes. Typical focus lock times hover around 0.8-1 second - adequate but noticeably slower than newer compacts.

• Sony TX20: Also contrast-based but enhanced with selective AF capability and touch focus. It boasts faster initial lock and improved subject tracking, albeit still constrained by the sensor size. Continuous AF is absent, but its 10fps burst shooting mode allows quick-fire capture of fleeting moments - a feature Canon entirely lacks.

For portraiture, both cameras deliver adequate eye detection for face-first framing; however, Sony’s touchscreen focusing enhances compositional freedom and speed.

Real-World Photography Scenarios

Let’s break down how these cameras perform across popular photography disciplines:

Portraits: Soft Skin, Natural Bokeh?

ELPH 135’s 8x zoom lens spanning 28-224mm equivalent provides excellent reach for portraits. However, its maximum aperture narrows to f/6.9 at telephoto, restricting depth of field control and low-light performance. The Sony TX20’s more modest 25-100mm f/3.5-4.6 zoom isn’t as telephoto-friendly for distant portraits but offers a faster aperture at the long end.

Both cameras render reasonably smooth bokeh at widest aperture but appear limited by sensor size and fixed lens optics; creamy background blur is subdued, lacking the signature “portrait look.” Skin tones on both cameras are generally pleasant, with the Canon’s slightly warmer rendering favored for natural warmth. Sony’s stronger dynamic range helps retain shadow nuance on faces with mixed lighting.

Landscapes: Crisper Details & Wide Views

Landscape shooters will appreciate Canon’s wider zoom range for framing broader vistas and tight compositional elements. However, Canon’s lower-resolution screen and noisier sensor can make judging sharpness and focus challenging outdoors.

The Sony’s superior screen and better dynamic range aid preview and capture of fine detail, especially in shadowed foliage or complex skies. Both cameras struggle with notable chromatic aberration toward edges, a common trait in ultracompacts.

Neither offers environmental sealing, though Sony’s modest splashproof rating (environmental sealing enabled) gives it a slight edge for adventurous shoots.

Wildlife & Sports: Can They Track Fast Action?

These models are not designed as action cameras, but it’s worth testing their limits.

The Canon’s slow 1 fps continuous shooting makes it ineffective for sports or wildlife tracking. The Sony’s 10 fps burst feels like a secret weapon here, despite lacking continuous AF - ideal for capturing a quick series of frames to select the best moment post-shoot.

Neither camera features sophisticated tracking autofocus or eye-detection for animals, which limits their viability for pro or dedicated wildlife work.

Street & Travel: Discretion & Portability

Both cameras excel in street and travel scenarios thanks to their snappy size and weight. Sony’s thinner body and touchscreen make it exceptionally pocketable, while Canon’s slightly chunkier grip provides steadier handling for quick snapper comfort.

Low-light street shooting reveals Sony’s higher ISO ceiling and optical stabilization outperform the Canon’s digital stabilization, resulting in sharper handheld photos. Battery life is slightly better on the Sony (about 250 shots per charge vs Canon’s 230), which can matter on day-long excursions.

Video Capabilities: HD to Full HD

Video remains a growing component of compact cameras - and this is where the Sony TX20 pulls ahead:

• Sony TX20: Records up to Full HD 1080p at 60fps, with AVCHD and MPEG-4 codecs. Optical image stabilization provides smooth footage, and the touchscreen eases focus pulls during recording. HDMI output allows direct playback on compatible devices.

• Canon ELPH 135: Limited to 720p at 25fps, using H.264 codec, with only digital stabilization available (less effective), and lacks HDMI output.

No microphone or headphone jacks on either camera means audio remains passable but not professional-level. However, I found the Sony’s video surfaces noticeably more stable and detailed - offering a usable clip quality for family moments and casual vlogging.

Macro & Night Photography: Close Focus & Low Light

Both cameras impress with close-focus capabilities - they can focus almost to 1cm, great for macro flower or small object shots. Sony’s manual focus option assists in precision here, though neither offers focus stacking or bracketing.

For night and astro photography, small sensors and limited ISO range curtail potential. The TX20’s ISO 3200 vs Canon’s 1600 ceiling, plus optical stabilization, lets Sony eke out cleaner, less noisy images under streetlights or dusk settings. But expect both to produce visible grain at extended ISOs.

Build Quality, Battery & Connectivity

Canon’s traditional build feels sturdy but plain plastic. Sony’s splashproof environmental sealing is a plus for casual weather resistance, a feature rarely seen in ultracompacts of this era.

Battery-wise, both use proprietary rechargeable packs; Sony’s NP-BN provides a slight advantage in longevity per charge, equating to longer shoots without spare batteries.

Connectivity is where Sony again shines, offering Eye-Fi wireless card compatibility for simple photo transfers; Canon offers no wireless or Bluetooth features, limiting instant sharing or remote control options.

Lens Ecosystem: Fixed by Design

Neither model supports interchangeable lenses - a restriction intrinsic to ultracompact cameras, prioritizing slenderness and simplicity over adaptability.

Canon’s more extensive zoom range imparts flexibility but narrower apertures limit creative effects. Sony’s more modest zoom struggles for reach but benefits from faster apertures for brightness and depth control.

Price & Value: Budget Choices for Specific Needs

At launch, the Canon ELPH 135 was priced near $120, starkly lower than the Sony TX20’s premium tier around $330. This price gap translates into a tangible difference in features - screen quality, video resolution, autofocus responsiveness - that enthusiasts would notice immediately.

Is the higher Sony price justified? If you prioritize better video, sharper LCD, splash resistance, and faster shooting, yes. For pure budget casual users content with snapshot JPEGs, Canon represents remarkable value.
