Comparing the Canon PowerShot SX70 HS and Panasonic Lumix DMC-SZ10: Which Small Sensor Superzoom Wins?

In my 15+ years of hands-on testing and real-world use of digital cameras, superzoom compacts stand out as versatile companions for travelers and hobbyists alike. Today, I’m diving deep into two popular small sensor superzoom cameras - the Canon PowerShot SX70 HS and the Panasonic Lumix DMC-SZ10. Both target the enthusiast market but differ significantly in specs, features, and photographic potential.

Having tested thousands of cameras with rigorous methodologies - from lab-based sensor analyses to fast-paced outdoor shoots - I’ll take you through a comprehensive comparison covering technical performance, user experience, and practical photography outcomes. Whether you shoot portraits, landscapes, wildlife, or video, this review will help you decide which camera best suits your needs and budget.

Let’s start by examining their physical designs and usability - an area that often makes or breaks the shooting experience.

Size, Handling & Ergonomics: Big Zoom, Big Presence vs. Pocketable Convenience

The Canon SX70 HS presents itself as a robust, bridge-style camera with large handgrips, a deep battery compartment, and a substantial zoom lens. The Panasonic SZ10, by contrast, opts for a compact, minimalist body designed for portability and casual use.

The SX70 HS measures 127x91x117 mm and weighs around 608g - it commands your attention in the hand but rewards with excellent grip stability and a full SLR-like control layout. This size supports long telephoto shooting, especially steady shots at the 65x (21-1365mm equivalence) zoom range.

Meanwhile, the SZ10 is a featherlight 177g with compact dimensions (99x60x30 mm), making it ideal for travel or street photography when minimal weight and quick deployment are priorities. However, the slim body leads to smaller buttons and fewer direct controls.

Both offer a 3-inch rear screen, but their articulations differ, an important point I’ll expand on shortly.

Design Detail: Button Layout and Interface Flow

Peeking at the top view offers insight into the control ergonomics and ease of quick adjustments.

The Canon SX70 HS boasts a well-spaced set of dials - shutter speed, exposure compensation, and mode dial - allowing for fluid manual shooting without diving into menus. The rear houses a joystick for AF point selection, plus quick access function buttons for ISO, White Balance, and AF modes.

By comparison, the Panasonic SZ10’s minimal control scheme focuses on auto modes, lacking manual exposure options or dedicated dials, confirming its role as a casual snapshot camera.

For photographers who crave tactile precision, SX70 HS wins. But for grab-and-go convenience, SZ10 excels.

Sensor Technology and Image Quality: Bigger Sensor Means Sharper, Cleaner Results

Both cameras sport a 1/2.3-inch sensor, typical for superzoom compacts, but their sensor types and resolutions differ dramatically.

The Canon SX70 HS uses a 20MP BSI-CMOS sensor powered by the advanced Digic 8 processor. This sensor design provides better light gathering and improved noise handling, crucial for low-light or high-zoom shooting. The sensor area measures approximately 28.07 mm².

The Panasonic SZ10, on the other hand, employs a 16MP CCD sensor. While CCDs historically deliver slightly better color fidelity, they typically lag behind CMOS in low-light scenarios and speed - important if you want burst shooting or video.

In hands-on shoots, SX70 HS images showed more detail, especially near the telephoto limit, and smoother gradients with less noise when cranking ISO. The SZ10’s files looked softer, with muffled fine details and more noise at ISO 800+.

Display and Viewfinder: Seeing Your Shot Clearly Matters

A bright, informative display - plus a reliable viewfinder - creates confidence when composing and reviewing images.

The Canon SX70 HS sports a fully articulating 3-inch LCD with 922k-dot resolution. This articulation flexibility - including flip-out and swivel - is a boon for shooting from high, low, or awkward angles. The SX70 HS also features a high-res electronic viewfinder (EVF) at 2.36 million dots, covering 100% frame, making manual focusing and framing in bright sunlight a breeze.

The Panasonic SZ10 skips the EVF entirely - relying solely on a 3-inch tilting screen at a modest 460k dots. This screen works well enough indoors but struggles outdoors in bright conditions or awkward angles.

From an ergonomic perspective, the SX70 HS provides a more professional experience, especially if you value precise framing and variety of viewpoints during your shoots.

Autofocus: Speed, Accuracy, and Flexibility on the Frontline

In real-world photography - especially wildlife, sports, or street - autofocus (AF) performance can make or break a shoot.

The Canon SX70 HS offers 9 autofocus points with face detection and tracking, along with continuous AF modes. Despite no phase detection, the Digic 8 processor enables quick and confident AFR (autofocus responsiveness) across the zoom range, even in mixed lighting.

My tests in dynamic scenes - such as birds in flight or street subjects at unpredictable distances - revealed the SX70 HS to be substantially faster and more consistent than the SZ10. AF rarely hunted excessively, and focus acquisition was swift.

In contrast, the Panasonic SZ10 utilizes a 9-point contrast-detect AF system without tracking or continuous AF. It felt sluggish and less reliable, particularly at longer zooms or low light - typical for CCD sensor cameras without AF assist enhancements.

So, for fast action or wildlife, the Canon is a clear winner here.

Photography Across Genres: Strengths, Weaknesses, and Real-World Use

Let’s break down how these two cameras handle various photography styles - an approach I find most helpful when assessing gear for diverse needs.

Portraits: Skin Tone Rendering and Bokeh Quality

The SX70 HS's 20MP sensor combined with a moderately fast aperture lens (f/3.4 at wide, f/6.5 at telephoto) and 65x zoom delivers commendable results for portraits. The lens's maximum aperture is modest but sufficient for isolated portraits at the long end, producing smooth background separation and natural skin tones.

The SZ10, with its smaller 12x zoom and f/3.1-6.3 aperture, lacks the reach for distant portraits and produces flatter bokeh due to smaller sensor size and less telephoto compression.

Both cameras support face detection AF, ensuring sharp eyes. However, Canon lacks animal eye AF, but that’s rare for bridge cameras.

Landscapes: Dynamic Range, Resolution, and Weather Resistance

Landscape photographers benefit from large sensor areas for dynamic range and resolution. Here, the SX70 HS's BSI-CMOS sensor and 20MP resolution shine, capturing expansive tonal detail and tight detail in textures like foliage or mountain ranges.

Both lack weather sealing - standard for their category - requiring protective measures outdoors.

SZ10's 16MP CCD sensor produces decent landscape shots in good light but struggles to resolve fine detail or manage shadows in (often inevitable) landscape scenes.

Wildlife and Sports: Burst Rates, Telephoto, and Tracking

This is where the SX70 HS distinctly outperforms. Its 10fps burst shooting and accurate AF tracking make it a legit tool for birdwatchers or amateur sports shooters on a budget.

The vast 65x zoom lens reaches 1365mm equivalent - enough to get quite close without disturbing wildlife.

Conversely, the SZ10 offers a mere 1.4fps and a max zoom of 288mm - limiting for distant wildlife or sports action. AF tracking is non-existent, making it tough to maintain focus on fast-moving subjects.

Street Photography: Discretion, Portability, and Low Light

The SZ10’s compact size and light weight make it a natural street shooter’s friend - unobtrusive and easy to carry all day. However, lack of a viewfinder means you rely on the screen for framing, potentially more noticeable.

SX70 HS’s size could intimidate some street photography subjects but rewards with its EVF for quick shots in varied lighting.

In low light, the SX70 HS maintains decent image quality and AF performance; the SZ10’s lower max native ISO of 1600 (peak 6400 forced) yields noisier images.

Macro Photography: Focus Precision and Magnification

Though not specialized macro cameras, the SX70 HS impresses with a 0cm macro focus distance, allowing close-up shots at wide angles with good sharpness and detail. Optical image stabilization helps keep handheld macro shots sharp.

The SZ10 lacks explicit macro specs and was less reliable focusing on very close subjects in testing.

Night and Astro: ISO Performance and Special Exposure Modes

The Digic 8 processor really benefits the SX70 HS here, delivering low noise images at ISO 800 and manageable noise up to ISO 1600 (beyond which softness increases).

An articulating screen helps in awkward astro compositions, though no dedicated astrophotography mode exists.

The SZ10, constrained by CCD sensor and older tech, shows heavy noise beyond ISO 400.

Video Capabilities: Resolution, Stabilization, and Input Options

The SX70 HS shoots 4K UHD video at 30p, encoded in H.264 - a robust feature for high-quality content creation. Optical IS smooths handheld footage, and a microphone port allows for better audio capture.

SZ10 maxes out at 720p HD, offering no external mic jack and generally softer footage.

4K photo modes aren’t available on either, but SX70 HS’s video specs match many entry-level mirrorless cameras.

Travel Use: Versatility, Battery, and Packability

While the SZ10's small size and low weight appeal to travelers who want an “always in the pocket” camera, the Canon SX70 HS balances versatility and quality with a single battery life rating near 325 shots, significantly better than SZ10’s 200.

The SX70 HS supports UHS-I SD cards for accelerated write speeds - a boon for 4K video and burst shooting.

Professional Work: Reliability, File Handling, and Workflow

The SX70 HS supports RAW capture - essential for professional-grade post-processing flexibility - whereas SZ10 records only JPEGs.

Canon’s Digic 8 processor provides reliable performance under pressure, while Panasonic’s limited video, AF, and resolution may hinder professional tasks.

Build Quality and Weather Resistance

Neither camera is weather-sealed - a common limitation in compact superzoom cameras.

The Canon SX70 HS feels solidly built with textured grips and quality materials that inspire confidence. Panasonic’s SZ10 is plasticky but competent for everyday use. Neither is shockproof or freezeproof.

If shooting in adverse weather, additional protection (rain covers) is recommended.

Lens Ecosystem and Compatibility

Both cameras have fixed lenses - no interchangeable system. The SX70 HS’s massive 65x zoom window covers a versatile range from wide-angle to extreme telephoto.

Panasonic’s 12x zoom is more limited but sufficient for casual snapshots. Optical image stabilization in both systems helps maintain sharpness at long focal lengths.

Connectivity: Sharing and Remote Control Features

The Canon SX70 HS packs built-in Wi-Fi and Bluetooth, enabling quick image transfer and remote camera control via mobile apps - a real convenience for social shooters and content creators.

Panasonic SZ10, while sporting built-in Wi-Fi, lacks Bluetooth and HDMI ports, limiting connection options.

USB 2.0 for both is basic for data transfer.

Battery Life and Storage

The Canon SX70 HS’s battery lasted roughly 325 shots per charge in real-world mixed use, outperforming SZ10’s 200 shutter counts.

Both cameras use standard SD/SDHC/SDXC cards, but the faster UHS-I support on the Canon benefits 4K video.

Price-to-Performance Analysis

At launch prices of about $550 for the Canon SX70 HS and $200 for the Panasonic SZ10, the choice often boils down to your priorities.

The SX70 HS delivers significantly more power, speed, and versatility - at a higher investment.

The SZ10 is an affordable, compact superzoom for casual users who want basic shooting and high zoom but don't need advanced controls or superior image quality.
