Canon SX150 IS vs Canon SX520 HS

Canon PowerShot SX150 IS vs SX520 HS: A Detailed Comparison for Serious Enthusiasts and Budget-Conscious Photographers

In this comprehensive comparison, we scrutinize two notable compact superzoom cameras from Canon’s PowerShot line: the SX150 IS and the SX520 HS. Both target enthusiasts seeking versatile zoom ranges in a small form factor, yet they diverge significantly in technological generation, sensor design, lens specification, and everyday usability. Drawing from extensive hands-on evaluation and industry-standard testing protocols, we dissect their imaging capabilities, operational ergonomics, autofocus systems, and value proposition. Our aim is to equip serious photography enthusiasts and professionals with practical insights that transcend marketing claims, enabling informed acquisition aligned to specific photographic disciplines and workflow needs.

Physical Dimensions and Handling: Ergonomics in a Compact Body

A critical facet for photographers balancing portability with stable handling is physical size and control layout. The SX150 IS measures a compact 113 x 73 x 46 mm, weighing approximately 306 grams powered by two AA batteries. Conversely, the SX520 HS is notably bulkier at 120 x 82 x 92 mm and about 441 grams, using a proprietary rechargeable battery pack (NB-6LH).

While the SX150’s smaller footprint facilitates pocketability for travel and street photography, its ergonomics reflect a utilitarian design with limited grip contouring and control separation. The reliance on AA batteries, while convenient for quick replacements, results in shorter battery life and increased weight penalty over extended shoots.

The SX520 HS’s larger dimensions afford improved handhold comfort and potentially enhanced operational precision, albeit at the cost of less discreet and more cumbersome carriage. Its integrated battery pack delivers approximately 210 shots per charge, nearly doubling SX150’s 130-shot expectancy with AA cells. This extended endurance addresses the needs of prolonged outdoor sessions, such as wildlife or travel photography.

Control Interface and User Experience: Top Deck and Rear Screen

Operating efficiency hinges on intuitive button layout, display clarity, and feedback responsiveness. Both cameras employ a fixed 3-inch LCD screen; however, the SX150’s display resolution is a basic 230K dots compared to the SX520’s sharper 461K dots panel, improving image review accuracy and menu navigation.

Neither model incorporates a touchscreen nor electronic viewfinder, constraining framing precision under bright ambient conditions and limiting tactile control advantages. The SX520 holds an edge with its processed layout featuring 9 autofocus points versus the SX150’s single AF point, enhancing user control in focusing scenarios.

Sensor Technology and Imaging Performance: CCD versus BSI-CMOS

A pivotal distinction lies in sensor architecture. The SX150 IS relies on a CCD sensor, 1/2.3-inch in size, with a 14-megapixel resolution. This older technology inherently produces higher noise at elevated ISOs and slower readout speeds, negatively impacting low-light and burst shooting. The sensor’s anti-alias filter helps mitigate moiré but also slightly softens fine detail rendering.

The SX520 HS upgrades to a BSI-CMOS sensor of identical size but with 16 megapixels and back-illuminated design, facilitating improved light-gathering efficiency and higher ISO usability, up to 3200 native ISO compared to SX150’s ceiling at ISO 1600. CMOS sensors generally afford faster data throughput, enabling the SX520’s increased continuous shooting rate (2 fps vs. 1 fps) and Live View autofocus performance.

The sensor size commonality sets a baseline for dynamic range and noise floor - both cameras are constrained by the small sensor physical limits, with neither providing RAW capture capability, thus tethering photographers to JPEG output quality and reduced post-processing flexibility.

Lens Range and Aperture Characteristics: Reach Versus Speed

The optical zoom represents a primary purchase driver in the superzoom category. The SX150 offers a 12x zoom spanning 28-336mm equivalent focal length, with a maximum aperture range of f/3.4 to f/5.6. This setup suits general use but somewhat limits telephoto flexibility for distant subjects and restricts bokeh potential due to aperture constraints.

Significantly, the SX520 extends the zoom factor to a staggering 42x, covering 24-1008mm equivalent. The slightly wider wide-angle end (24mm) improves landscape framing, while the telephoto maximum greatly benefits wildlife and sports photographers needing extended reach without lens swaps. Aperture speeds taper to f/3.4-6.0, indicating dimming lens speed at full zoom, which combined with sensor limits, challenges image quality in low light at longer focal lengths.

The optical image stabilization in both units mitigates hand shake, with SX520’s system expected to be more advanced given release year improvements and the long lens extension.

Focus Systems: Contrast Detection and Autofocus Point Coverage

Both cameras utilize contrast-detection autofocus in Live View and optical zoom modes. The SX150 IS is limited to a single AF point with face detection enabled; while adequate for static subjects and casual composition, it restricts flexible focusing in fast-paced scenarios.

By contrast, the SX520 HS expands AF points to nine, allowing finer subject tracking and better framing composition for action and wildlife contexts. Additionally, the SX520 supports continuous autofocus during bursts, boosting hit rates on moving targets, a non-trivial advantage for sports photographers or nature observers.

Neither model supports phase detection or hybrid systems found in more recent mirrorless designs; this results in generally slower subject acquisition and occasional hunting under dim or low-contrast conditions.

Shooting Modes and Exposure Control

Both cameras provide the standard exposure modes of shutter priority, aperture priority, manual exposure, and exposure compensation. Custom white balance controls and face-detection assist with more accurate skin tones during portraits, though limitations exist due to sensor and processing constraints.

The SX520 includes white balance bracketing - a useful feature missing from the SX150 - permitting incremental white balance adjustments in a single capture sequence to optimize color rendition. Exposure bracketing is not supported on either camera, limiting bracketed HDR workflow options.

Continuous shooting maxes out at 1 fps for the SX150 and 2 fps on the SX520, modest by current standards but usable for casual photography.

Video Capture Capabilities

Modern hybrid usage demands good video performance; here, both cameras deliver HD recording but with marked differences.

The SX150 records a maximum of 1280x720p at 30 fps in H.264 format without external mic input or headphone monitoring, limiting professional sound control. Frame rates are strictly locked without higher-speed or 4K options.

More significantly, the SX520 HS elevates maximum video resolution to full HD 1920x1080 at 30 fps, supporting MPEG-4 and H.264 compression. While lacking advanced video-centric features like 4K or external audio jacks, it offers HDMI output for streamlined capture and display on external monitors. Internal image stabilization helps with panning smoothness during hand-held video.

Neither model supports time-lapse or high frame rate slow motion, reflecting their basic compact superzoom lineage.

Battery, Storage, and Connectivity

Battery life considerations directly influence usability during extended sessions. The SX150’s use of standard AA batteries is a double-edged sword: while universally available and easy to replace, the limited 130 shots per set highlights inefficiency and frequent interruptions.

The proprietary NB-6LH battery in the SX520 delivers nearly 60% more captures per charge (210 shots), which, combined with USB 2.0 charging, supports more reliable shooting days. Storage options are identical, supporting SD/SDHC/SDXC cards in a single slot.

Connectivity differs notably: the SX150 features Eye-Fi card compatibility for wireless transfer, an uncommon inclusion for its generation, although actual transfer speeds and reliability depend on card firmware and infrastructure. The SX520 lacks wireless features, requiring USB or HDMI connections for file transfer.

Build Quality and Weather Resistance

Both models lack specialized environmental sealing or ruggedized features, constraining use in adverse weather or extreme environments. Neither is waterproof, dustproof, shockproof, or freezeproof.

The SX520’s heftier build implies more internal volume potentially allowing better heat dissipation during video recording or burst shooting, but the lack of sealing remains a limitation for professional outdoor use.

Image Sample Quality and Practical Results

We tested both cameras under controlled conditions and varied real-world scenarios to assess image sharpness, color accuracy, noise levels, and bokeh rendition particularly in portraiture.

The SX520’s BSI-CMOS sensor demonstrates visibly cleaner high ISO images and greater detail retention in shadows compared to the SX150’s CCD. Its wider zoom and longer reach reveal better subject isolation potential, though maximum aperture narrowing at focal length extremes mandates higher ISO selection disproportionately under low light.

Skin tones render subtly warmer on the SX150, arguably favorable for portraiture, albeit at the cost of increased noise. Both cameras exhibit noticeable chromatic aberrations and distortion towards the telephoto ends, typical for fixed superzoom optics in this class.
