Canon PowerShot SX520 HS vs. SX70 HS: An Expert Comparison to Find Your Perfect Superzoom

When browsing the compact superzoom camera segment, Canon’s PowerShot lineup consistently draws attention. Two prominent models, the SX520 HS and the newer SX70 HS, offer significant zoom power and feature sets, but cater to different users and creative ambitions. Having tested both extensively in various photography disciplines, from landscapes to wildlife, and examined their tech inside-out, we’re diving into a detailed comparison to help you discover which Canon superzoom fits your vision and style best.

Whether you’re a casual travel shooter, enthusiast wildlife photographer, or budding videographer, this analysis will cover every crucial aspect - sensor technology, autofocus, ergonomics, lens reach, and real-world image quality - to empower you to make an informed choice.

A Tale of Two Superzooms: Design and Ergonomics at a Glance

Let’s first compare how these cameras feel in your hands, because handling can make or break your shooting experience, especially with long zoom ranges.

At a glance, the SX520 HS is genuinely pocket-friendly, making it easy to slip into a jacket or day bag. Its minimalist compact design suits casual shooting, but you’ll miss a viewfinder for bright outdoor work or action shots.

The SX70 HS adopts a more substantial bridge camera form factor - a larger electronic viewfinder, solid handgrip, and an articulating screen. This design encourages steady shooting, especially at the long end of its 65x zoom range. It’s less portable but delivers professional handling comfort and stability critical in wildlife or sports photography.

Under the Hood: Sensor and Image Quality Differences

Sensor tech defines the quality baseline for your images, and both cameras use the same 1/2.3-inch BSI-CMOS format but differ in resolution and processing power.

The SX70 HS benefits from its newer DIGIC 8 processor and increased 20MP resolution that offer nuanced improvements in image sharpness and noise control. Its RAW shooting capability is a significant advantage for post-processing professionals or enthusiasts craving full control over color and exposure. The SX520 HS, using an older DIGIC 4+ chip and capped at JPEG, is more limited for creative editing.

When shooting landscapes or static subjects, the SX70’s extra detail and subtly better dynamic range (thanks mainly to processing advances) become evident. However, in good light, both can produce pleasant images - though you should not expect DSLR-level quality due to the small sensor size.

Lay Your Eyes on the Prize: Viewfinder and LCD Screen

Shooting composition and review workflows depend heavily on your interface with the camera.

The SX70 HS’s electronic viewfinder (EVF) is a decisive benefit, especially in bright daylight or when tracking moving subjects through its long telephoto zoom. An articulated rear screen adds versatility for awkward angles and video vlogging. On the other hand, the SX520 HS’s fixed and lower-res LCD is functional but less flexible -

without EVF, you might struggle in bright sunny conditions where glare hinders clear framing.

Zoom vs. Reach: Lens and Autofocus Performance

Superzoom cameras thrive or fail on their reach, image stabilization, and focusing systems.

The SX70 HS not only expands zoom reach from 42x to an impressive 65x - ideal for distant wildlife or sports - but also upgrades autofocus with selectable focus areas and better face tracking. This difference translates into more reliable focus lock, especially for fast-moving subjects or when shooting at long focal lengths.

The SX520 HS’s slower autofocus and more modest zoom limit its use for demanding telephoto needs but still cover general travel and casual wildlife shots.

Fast Action Captured: Burst Speed and Shutter Performance

Continuous shooting speeds dictate how well you’ll freeze sports or wildlife action.

Compared side-by-side, the SX70 HS’s 10 fps burst rate is significantly better than the SX520’s 2 fps, providing a much higher chance to capture the decisive moment in fast-paced action. Both limit shutter speeds to 1/2000 sec, adequate for most daylight shooting.

Shooting in the Dark: ISO Performance & Low-Light Usability

Small sensor cameras often struggle beyond ISO 800, so let’s examine low-light capabilities.

| ISO Range | Both | 100-3200 | | Noise Performance | Moderate noise visible over ISO 800 | Cleaner images to ISO 1600 due to DIGIC 8 |

Thanks to the advanced DIGIC 8 processor, SX70 HS images maintain cleaner detail and better noise control at higher ISO settings compared to the older SX520 HS. This also indirectly benefits video capture and handheld shooting in dim environments.

Video Recording: Stepping Up the Game

Both cameras offer video, but again the SX70 HS brings modern specs and versatility.

If video is a key part of your creative journey, the SX70 HS is a clear winner. Its ability to shoot crisp 4K footage with microphone input support expands your options for vlogging, short films, and creative projects. The SX520 HS recording ends at Full HD without audio inputs, limiting production quality.

Building for the Field: Durability, Weather Resistance, Battery & Storage

Shooting outdoors and on the go demands practical considerations.

Neither camera offers weather sealing, so you’ll want to avoid heavy rain or dusty environments. The SX70 HS’s significantly better battery life of roughly 325 shots versus 210 on the SX520 HS increases your shooting sessions without frequent recharging or battery swaps.

Wireless features like Wi-Fi and Bluetooth in the SX70 allow quick image transfer to your phone or remote control - a boon for social media sharing or remote shooting setups. The SX520 lacks any form of wireless, requiring physical cable connections.

User Interface and Controls: How Intuitive Are They?

Both cameras provide manual controls, but the implementation differs greatly.

The SX70 HS mimics a DSLR-style layout with dedicated dials for exposure compensation, mode selection, and zoom control - bringing tangible benefits in quick adjustments and precise shooting. The SX520 HS is more minimalist, which simplifies operation for beginners but limits manual creativity and rapid control.

Performance by Photography Genre: Which Suits Your Style?

Each camera excels in different photography niches. Here is an expert scoring overview:

Portrait Photography:

• SX70 HS edges ahead with eye detection and higher resolution for better skin tone rendering and pleasing bokeh thanks to advanced zoom optics.
• SX520 HS is serviceable but lacks selective autofocus or RAW for fine skin tone editing.

Landscape Photography:

• Both share the small sensor’s resolution limits, but SX70’s higher megapixels and articulating screen help framing and detail retention in RAW.

Wildlife & Sports Photography:

• SX70 HS excels with fast burst rate, longer zoom (65x), and improved AF tracking.
• SX520 HS falls short due to slower AF and continuous shooting.

Street Photography:

• SX520 HS’s compact body makes it more discreet on the street.
• SX70 HS is bulkier but better for low-light scenes due to improved ISO and viewfinder.

Macro Photography:

• Both have limited macro focusing distances (~0 cm from lens front), but SX70 HS’s better manual focus control is helpful.

Night and Astro:

• SX70 HS gives better ISO performance for night shots, while neither is ideal for detailed astro photos due to sensor size.

Video Creation:

• SX70 HS dominates with 4K, mic input, and timelapse.

Travel Photography:

• SX520 HS is lighter and easier to carry.
• SX70 HS offers more versatility and longer battery life.

Sample Images: Real-World Image Quality Comparison

To help you visualize differences, here are sample photos from both cameras under typical shooting conditions:
