Canon G11 vs Canon SX240 HS: An Expert Hands-On Comparison for Photography Enthusiasts

When stepping up from smartphone snaps or entry-level cameras, Canon’s PowerShot series has long presented compelling compact options blending portability with creative control. Today, I’m diving deep into two classic Canon compacts - the Canon PowerShot G11 from 2009 and the slightly newer Canon PowerShot SX240 HS from 2012. Both cameras cater to the enthusiast crowd but take fundamentally different approaches: the G11 aiming for high image quality and manual control in a semi-pro compact shell, and the SX240 HS targeting the versatile superzoom segment.

After hours of side-by-side testing, scrutinizing specs, handling, and output, I’ll dissect their key differences and similarities across major photography disciplines - from portraits to wildlife, landscapes to video - to help you decide which might best suit your creative goals today. Let’s jump in.

First Impressions: Size, Build, and Handling

Canon designed the G11 as the serious enthusiast’s compact: a chunky, solid-feeling brick with a well-damped D-Pad, an articulating rear screen, and a full suite of exterior dials and buttons. The SX240 HS, by contrast, is noticeably smaller and lighter, having traded bulk for reach - its 20x zoom is impressive in such a slim body.

In practice, the G11’s larger grip and heft provide a reassuring, balanced feel, especially with longer shooting sessions or when mounting on a tripod. Its fully articulated 2.8-inch screen allows flexible framing from creative angles. The SX240 HS sports a fixed 3-inch PureColor II TFT LCD; while the larger screen area is pleasant, the lack of articulation does limit compositional versatility.

Ergonomically, the G11’s manual focus ring and dedicated exposure controls put more power literally at your fingertips - perfect for photographers who prefer tactile feedback - while the SX240 HS relies more on menus and less intuitive button layouts, typical of many superzoom compacts.

For travel photography, the SX240 HS wins on size and weight, easing fatigue and packing ease. But if you want ergonomic refinement and instant access to controls, the G11 demands attention.

Sensor and Image Quality: Chip Fundamentals and Output

At the heart of any camera lies the sensor, and here the Canon G11 and SX240 HS differ significantly in size, type, and resulting image quality.

Canon G11’s 1/1.7-inch CCD Sensor

• Measures approximately 7.44 x 5.58 mm (41.52 mm²)
• 10 MP resolution (3648 x 2736 pixels)
• Equipped with Canon’s Digic 4 image processor
• Supports RAW image capture for maximum post-processing flexibility

Canon SX240 HS’s 1/2.3-inch BSI-CMOS Sensor

• Smaller 6.17 x 4.55 mm (28.07 mm²) sensor area
• Higher 12 MP resolution (4000 x 3000 pixels)
• Powered by Digic 5 processor
• No RAW support; shoots only JPEG

Though the SX240 HS brings a newer back-illuminated CMOS sensor design capable of better sensitivity, the G11’s larger surface area CCD captures more light per pixel. This translates to superior color depth and dynamic range in real-world shooting, as confirmed by DxOMark’s detailed measurements: the G11 shows an impressive 20.4 bits of color depth and dynamic range surpassing 11 stops, compared to the unrealized but expectedly lower in-camera RAW processing of the SX240 HS.

I noticed cleaner shadows, more nuanced skin tones, and stronger highlight retention from the G11’s RAW files. At higher ISOs (1600-3200), the G11 maintains better noise characteristics than the SX240 HS’s JPEG output - a reflection of both sensor and processing differences.

For landscape and portrait work demanding latitude in post, the G11’s RAW capability is a winner; the SX240 HS fits good casual shots but less so for critical processing.

Autofocus and Performance: Speed, Precision, and Tracking

When shooting wildlife, sports, or fast-moving street scenes, autofocus (AF) speed and accuracy become critical.

The G11’s AF system uses 9 contrast-detection points with face detection and multi-area coverage enabled in live view mode. However, continuous AF tracking is basic and slow, as is typical for contrast-based systems of the era. Continuous shooting maxes at a modest 1 fps, limiting burst opportunities.

In contrast, the SX240 HS employs 9-point contrast-detection AF with face detection and added AF tracking capabilities, yielding smoother continuous AF performance. Burst rate is doubled to 2 fps, aiding capture of fleeting moments. AF tracking is more responsive but still far from professional-grade phase-detection systems.

While testing in wildlife scenarios, I found the SX240 HS’s AF quicker to lock on moving subjects but struggled in low light or low contrast - a reflection of its smaller sensor and narrow aperture at long focal lengths. The G11 required more patience but rewarded with precise focus once locked.

Neither camera shines as a sports autofocus powerhouse, but the SX240 HS theoretically offers a slight advantage for casual action with its longer zoom and improved tracking.

Lens and Zoom: Focal Range Flexibility and Optical Quality

Lens design reveals each camera’s target audience and typical use cases.

The G11’s 5x zoom is modest by modern standards but features a bright aperture at the wide end and smooth optical quality. Its lens blur transition to background (bokeh) is pleasing for portraits, with a softly rendered depth that complements its medium sensor perfectly.

The SX240 HS’s 20x superzoom pushes the telephoto limit to an equivalent 500mm, allowing spontaneous wildlife or sports compression that the G11 simply can’t rival. However, the narrow max aperture at the tele end means you’ll be relying on good light or high-ISO settings to maintain shutter speeds, which can impact image quality.

For macro work, the G11’s near-1cm focus distance means serious close-up potential, aided by image stabilization that guards against handshake at those tight magnifications. The SX240 HS allows macro shooting at 5cm - closer than average but nowhere near the G11’s controlled scope.

If zoom flexibility is your top priority - travel wildlife or street captures from afar - the SX240 HS is compelling. But for critical portraits, macro, or landscapes where clarity, bokeh quality, and lens speed matter, the G11 holds commanding ground.

Display and User Interface: Viewing and Control

The rear display and control layout factor heavily into how intuitively a camera operates in the field.

The G11’s 2.8-inch fully articulated screen swivels and tilts with a bright 461k-dot resolution, perfect for shooting from low angles or awkward positions. This articulation encourages creative compositions often neglected in compact cameras. The optical tunnel viewfinder offers an alternative framing option, though it lacks electronics and can feel outdated - yet handy in bright daylight.

In contrast, the SX240 HS features a slightly larger but fixed 3-inch PureColor II TFT LCD of comparable resolution (461k dots) without any viewfinder. It depends entirely on its rear screen, which can hinder stable eye-level shooting in bright environments.

Functionally, the G11 offers dedicated, illuminated buttons (helpful in low light), manual dials for aperture/shutter adjustment, and dual dial control for exposure compensation and ISO - a boon for experienced users needing rapid adjustments.

The SX240 HS adopts a simpler button layout, relying on menus accessed through directional pads. While neat for casual owners, it can frustrate manual shooters looking for efficiency.

On the whole, the G11’s interface suits serious enthusiasts juggling manual modes, while the SX240 HS targets users wanting easy shooting with occasional manual overrides.

Battery and Storage: Power Management and Capacity

Endurance is often overlooked until you’re stranded mid-shoot.

The G11 uses Canon’s NB-7L rechargeable lithium-ion battery pack, bundled with no official CIPA rating published but known to deliver approximately 200-250 shots per charge under typical use. Its power consumption is higher, given the larger sensor and articulated screen.

The SX240 HS utilizes the lighter NB-6L battery rated for around 230 exposures per charge - surprisingly competitive considering its smaller size. The camera offers only one SD/SDHC/SDXC storage slot, similar to the G11’s SD, SDHC, MMC compatibility.

In practical terms, both are average in stamina, requiring spares or charging opportunities during intensive travel or day-long shoots.

Video Capabilities: Moving Beyond Stills

Despite arriving during a shift towards HD video, these cameras occupy different tiers of video functionality.

The G11 records basic VGA resolution (640x480) at 30 fps, capturing H.264-encoded clips with limited manual control. It lacks external microphone input and advanced features like image stabilization in video mode.

The SX240 HS advances solidly into HD territory - offering full 1080p video at 24 fps, 720p at 30 fps, and even higher frame rate 480p slow-motion capture up to 120 fps, and 240 fps at 320x240 resolution for creative effects. Optical stabilization benefits video quality, but microphone input and headphone ports remain absent.

If video matters to you, especially HD capture or slow-motion, the SX240 HS significantly outperforms the G11, making it suitable for casual videography alongside stills.
