Canon PowerShot SX150 IS vs SX400 IS: In-Depth Comparison for Photography Enthusiasts and Professionals

When considering an affordable superzoom compact camera, Canon’s offerings in the mid-2010s PowerShot lineup frequently come to mind. Two models that often surface in purchasing debates are the Canon PowerShot SX150 IS and the Canon PowerShot SX400 IS. Released roughly two years apart, these cameras share similarities as small sensor superzooms but demonstrate meaningful distinctions in features, operation, and image quality potential.

Having spent extensive time testing both models across a range of practical shooting scenarios - from portraits and landscapes to travel imaging - this comparison draws on systematic evaluations and hands-on experience. It covers sensor technology, autofocus, optics, usability, and more, providing an authoritative resource for enthusiasts and professionals considering either as a budget-conscious secondary camera or for entry-level superzoom use.

Physical Handling and Ergonomics: Size and Control Layout

Starting with form factor and ergonomics, both models aim at ease of use typical for compact superzooms, though differences in design philosophy are evident.

• Canon SX150 IS: Measures roughly 113 x 73 x 46 mm and weighs 306 grams. The size is slightly chunkier relative to the SX400 IS but remains comfortable for average-hand users.
• Canon SX400 IS: More compact laterally with dimensions around 104 x 69 x 80 mm, but noticeably thicker (largely due to lens assembly), weighing 313 grams.

Both cameras employ a fixed lens with no interchangeable lens mount, limiting adaptability but maintaining compactness. The SX150 IS offers manual focus capabilities, which can aid in technical shooting and macro work, whereas SX400 IS does not.

Examining control layout, both cameras prioritize simplicity, avoiding extensive manual dials.

The SX150 IS uses a single control dial and a directional pad with dedicated buttons to access key settings, supporting manual exposure modes including aperture and shutter priority. This benefits photographers who prefer creative control.

Conversely, the SX400 IS streamlines the interface further, sacrificing manual exposure modes for more automation. It utilizes fewer external controls, focusing on point-and-shoot functionality.

Ergonomic note: The SX150 IS’s balance and button placement support steadier handheld shooting for extended periods, while the SX400 IS, though sleeker, feels less intuitive for manual operation.

Sensor Technology and Image Quality Potential

Both cameras use a 1/2.3-inch CCD sensor with identical physical dimensions (6.17 x 4.55 mm), but the SX400 IS sports a modest resolution increase to 16 megapixels versus SX150 IS’s 14 megapixels.

CCD technology was standard in compact cameras of their era, known for vibrant color reproduction at low ISOs, but limited high-ISO performance and dynamic range compared to more modern CMOS sensors. Both cameras have an identical maximum native ISO of 1600, though neither supports expanded ISO modes.

In practice, the image quality difference between the two models is marginal given sensor equivalence and lens aperture ranges. However, the SX400 IS’s increased pixel count results in slightly more detailed images when lighting is adequate.

Key limitations with both include:

• Limited low-light performance: Noise becomes apparent beyond ISO 400.
• Restricted dynamic range: Shadows lose detail under high contrast conditions.
• No RAW image support: Files come only in JPEG, restricting post-processing latitude.

For photographers prioritizing image fidelity, especially under challenging lighting or requiring flexible editing, these constraints warrant serious consideration.

Lens and Zoom Performance

Lens design is a central factor for superzoom compact cameras.

• SX150 IS: Offers a 28-336 mm equivalent focal range (12x zoom), aperture f/3.4-5.6.
• SX400 IS: Significantly extends this to 24-720 mm equivalent (30x zoom), aperture f/3.4-5.8.

This marks a major zoom advantage for the SX400 IS, enabling much longer reach suitable for wildlife, distant sports, or travel where lens changes are impractical.

The wider 24 mm starting point on the SX400 IS also offers greater versatility for landscapes and interiors compared to 28 mm on the SX150 IS.

Both cameras feature optical image stabilization, critical for handheld superzoom shooting to reduce blur. Canon employs similar optical stabilization technology in both, with no distinct superiority.

Performance caveats:

• At maximum telephoto ends, image quality softens significantly on both cameras due to smaller apertures and optical compromises typical in superzoom lenses.
• Macro focusing distance is slightly better on the SX150 IS (1 cm vs. 0 cm reported on the SX400 IS, which likely means minimum focus at lens front), benefiting close-up shooters.

The SX400 IS’s longer zoom range imposes a heavier lens assembly, impacting heft and sometimes balance.
