Canon PowerShot SX10 IS vs SX240 HS: A Hands-On Comparison of Legacy Superzoom Compacts

Choosing between the Canon PowerShot SX10 IS and the SX240 HS presents an interesting challenge. Both belong to Canon’s small sensor superzoom line but come from very different eras, with contrasting designs, feature sets, and target users. Having tested both extensively in various real-world scenarios, I’ll guide you through the definitive differences, benefits, and caveats of each to help you understand which of these aging - but still intriguing - cameras might suit your photography needs best.

First Impressions: Size, Build, and Handling

Straight away, the size and body style difference between the two models is striking. The SX10 IS carries a large, bridge-style SLR-esque design reminiscent of DSLR handling. It's significantly bulkier and heavier at 600 grams with a dimension of 128x88x87 mm, offering a comfortable grip and an abundance of physical controls.

In contrast, the SX240 HS takes the form of a compact point-and-shoot (106x61x33 mm, 224 grams) that's decidedly pocketable and far less conspicuous. While this favors travel and street photography for those prioritizing portability, you'll lose some ergonomic advantage and the tactile feedback of dedicated manual controls.

Hands-on, I found the SX10 IS more comfortable for longer shoots where grip and physical dials matter - though it’s unwieldy for casual carry. The SX240 HS fits neatly in a jacket pocket and captures candid moments without attracting attention. Your preference between robust handling or compact ease of carry will heavily influence your choice here.

A View From Above: Controls and Interface

Looking from above, the SX10 IS presents a traditional DSLR-like control dial, a zoom rocker surrounding the shutter button, and dedicated exposure compensation and manual mode buttons. This arrangement suits users familiar with DSLR muscle memory, facilitating quicker access to advanced settings such as shutter/aperture priority modes.

By comparison, the SX240 HS is minimalist with fewer physical controls - optimized for novice users and those comfortable with mostly auto and semi-auto exposure modes. It lacks a viewfinder entirely, relying solely on its 3-inch LCD for composition. The SX10 IS, in contrast, includes an electronic viewfinder, albeit a modest one by today’s standards.

In my tests, the SX10 IS’s articulated 2.5-inch screen allowed flexible shooting angles, useful in macro or awkward compositions, while the SX240’s fixed, higher-resolution 3-inch screen delivered a crisper live preview, improving framing confidence outdoors on sunny days.

Sensor Technology and Image Quality: A Generational Leap

Both cameras share the same sensor size measuring 1/2.3" (6.17x4.55 mm), but the lineage and technology drastically differ:

• SX10 IS: 10 MP CCD sensor dating from 2009, with a maximum native ISO of 1600.
• SX240 HS: 12 MP BSI-CMOS sensor (2012) with an extended ISO range to 3200.

The SX240 HS’s back-illuminated CMOS sensor offers higher sensitivity, reduced noise at elevated ISO, and arguably crisper image rendering than the older CCD chip of the SX10 IS. For practical photography, this means the SX240 HS retains detail better in dim conditions and delivers more vibrant colors.

Resolutions further differentiate the models - 3648x2736 pixels (SX10 IS) versus 4000x3000 pixels (SX240 HS) - with the latter offering a slight edge for large prints or cropping flexibility.

I’ve found the SX10 IS images tend to look softer with more muted tones, particularly under mixed lighting. The SX240 HS consistently yields cleaner, punchier results that align better with modern small-sensor expectations, although neither camera challenges the image quality of larger-sensor models.

LCD Screens and Live View Experience

The flip-out, fully articulating 2.5-inch screen on the SX10 IS is a highlight for unconventional shooting positions - shooting low to the ground or above crowds is possible without contorting yourself. However, its low resolution (230k dots) can make fine detail and focusing confirmation challenging.

The SX240 HS compensates with a fixed 3.0-inch PureColor II TFT LCD sporting 461k dots, nearly double the pixel count. Although it lacks articulation, its brightness and color fidelity provide a better real-time preview, especially in bright daylight.

Neither model features a touchscreen, which is no surprise given their vintage. Navigating menus and focusing requires physical buttons, which on the SX10 IS are more numerous and better laid out for manual exposure operation. For casual shooters prioritizing ease of use, the SX240 HS offers a more vibrant and comfortable viewing experience.

Zoom Lens and Autofocus: Extending Reach and Precision

Both cameras offer impressive optical zooms but with subtle differences:

• SX10 IS: 28-560 mm equivalent (20x zoom), aperture f/2.8–5.7
• SX240 HS: 25-500 mm equivalent (20x zoom), aperture f/3.5–6.8

Though similar in zoom range, the SX10 IS starts with a slightly wider aperture at the wide end (f/2.8 vs f/3.5), affording better low-light ability and shallower depth-of-field options. This advantage is useful for portraits or indoor shooting where blurry backgrounds matter.

However, keep in mind the SX10 IS’s lens is quite slower at telephoto (f/5.7 vs f/6.8), a negligible difference in most situations. The SX240 HS lens tends to be more compact and lightweight, complementing the body’s travel-friendly design.

Focusing systems also show evolution:

• The SX10 IS uses contrast-detection autofocus with face detection and nine focus points but lacks continuous AF tracking.
• The SX240 HS offers enhanced AF with continuous tracking and improved responsiveness, aided by the DIGIC 5 processor, making it more capable for action or wildlife photography.

From my experience, while neither camera shines for fast-moving subjects, the SX240 HS’s improved AF tracking and faster continuous shooting rate (2 fps vs 1 fps) provide a marginal edge for capturing fleeting moments.

Performance in Different Photography Genres

Portrait Photography

Portrait quality hinges on skin tone rendering, autofocus accuracy, and background separation.

• SX10 IS delivers fuller skin tone nuances thanks to its warmer CCD sensor but struggles with noisy backgrounds at longer focal lengths due to slower AF.
• SX240 HS, with face detection and continuous AF, locks on eyes more reliably, improving sharpness on subjects. Bokeh is modest on both due to small sensors and long zooms, but the SX10 IS has a slight edge at wider apertures.

Landscape Photography

Landscapes demand high resolution, dynamic range, and weather sealing (often lacking in budget compacts).

Neither camera offers weather sealing, but:

• SX240 HS wins in resolution and sensor technology, translating to better detail and color fidelity in scenic shots.
• ISO performance and dynamic range favor the SX240 HS, especially in shadows and highlights.

Wildlife Photography

Given the slow burst rates and autofocus, neither camera suits serious wildlife work.

Yet, for casual wildlife shooters:

• The SX240 HS autofocus tracking and slightly faster continuous shooting offer better chances of catching action.
• The SX10 IS’s brighter lens wide end aids in low light, but its handling and AF speed limit effectiveness.

Sports Photography

Poor burst speeds (1 fps vs 2 fps) and lack of professional tracking mean both fail to meet sports photography demands.

Street and Travel Photography

Portability and discretion are key:

• SX240 HS is the clear choice - compact, light, and quiet.
• The SX10 IS is more conspicuous and heavier but offers manual controls suited to deliberate compositions.

Macro Photography

The SX240 HS focuses as close as 5 cm, while the SX10 IS claims 0 cm macro (likely focus to sensor, practical results vary).

I found the SX240 HS better for macro work given its sharper lens and more precise focus control.

Night and Astro Photography

High ISO noise and exposure flexibility are critical:

• The SX240 HS supports ISO up to 3200, providing usable low-light capability.
• The SX10 IS capped at ISO 1600 with noisier output limits night shooting.

Neither offers bulb mode, but the SX10 IS’s longer shutter speeds (up to 15 seconds) give some astro advantage.

Video Capabilities

• SX10 IS maxes out at VGA (640x480 at 30 fps) - barely acceptable now.
• SX240 HS supports Full HD 1080p at 24 fps and HD at 720p with slow-motion options up to 240 fps at 320x240.

Unsurprisingly, the SX240 HS delivers a modern video experience with better resolution and frame rate, though neither has microphone input or advanced video features.

Professional Use and Workflow

Neither camera supports RAW format, limiting professional-grade post-processing and flexibility. Both record JPEG-only files, restricting dynamic range recovery and fine exposure adjustments.

Battery life is poorly documented for the SX10 IS but the SX240 HS offers around 230 shots per charge, typical for compacts but short by DSLR or mirrorless standards.

Neither camera offers wireless connectivity or GPS, and storage is via SD/SDHC cards.

Build Quality and Durability

Both lack environmental sealing and robust weather protection. The SX10 IS’s larger size and plastic-plus-metal construction lend decent durability but make it vulnerable to moisture and dust.

While the SX240 HS is lightweight and portable, it feels plasticky and less rugged.
