Canon PowerShot A1100 IS vs. SX730 HS: An In-Depth Comparison for Enthusiasts and Pros

Choosing the right compact camera often means balancing portability, image quality, and feature set to fit very specific photography ambitions - be it casual snapshots, travel, or certain professional uses. Here, we take a highly detailed, experience-driven look at two Canon small-sensor cameras that, while related by brand and category, come from different eras and target somewhat different users: the Canon PowerShot A1100 IS (released 2009) and the more contemporary Canon PowerShot SX730 HS (launched 2017). Both fall in the compact segment leveraging a 1/2.3” sensor, yet their technologies and capabilities diverge sharply, reflecting eight years of Canon’s evolving compact camera innovations.

Drawing from over 15 years of camera testing across numerous brands, sensor technologies, and shooting styles, this article synthesizes technical comparisons, usability insights, and real-world performance to guide you toward the best fit. We pay close attention to sensor performance, autofocus, ergonomics, and specific photographic pursuits such as portraiture, wildlife, macro, and video - all critical for informed purchasing today.

Shape, Size, and Handling: How Ergonomics Affect Usability in the Field

Before diving into photography-centric specifics, understanding the physical factors can’t be overstated. Cameras that feel comfortable and intuitive to operate often enhance creativity and reduce fatigue over long shoots.

The A1100 IS is markedly more compact and lightweight, measuring 95×62×31 mm and weighing just 150 g powered by AA batteries, a traditional approach allowing replacement convenience but potentially less capacity. Its fixed LCD is a modest 2.5-inch display with 115k dots, and it features an optical tunnel viewfinder - albeit without magnification or coverage data - giving an alternative framing method in bright conditions.

Contrast this with the bulkier SX730 HS, at 110×64×40 mm and 300 g with dedicated rechargeable battery packs, doubling the mass but incorporating a larger and higher resolution 3-inch tilting screen with 922k dots. This articulating display significantly aids shooting from diverse angles, especially in street or travel photography scenarios. The SX730 forgoes any traditional viewfinder, relying solely on the LCD.

In terms of handling and control layout, the SX730 HS benefits from updated top-plate design and button placement, optimally balancing direct manual controls like shutter/aperture priority modes, exposure compensation, and manual focusing abilities, which the A1100 IS completely lacks. These enhancements make the SX730 better suited for photographers looking for creative control rather than just point-and-shoot simplicity.

Summary: For portability and absolute pocketability, the A1100 IS dominates; for ergonomic versatility and expanded control, the SX730 HS is clearly superior.

Sensor and Image Quality: The Heart of Photography

Sensor technology underpins every photographic outcome. Despite both cameras using the 1/2.3” sensor size (measuring 6.17×4.55 mm), their underlying sensor designs and resolutions differ significantly.

The A1100 IS uses a 12MP CCD sensor coupled with Canon’s older DIGIC 4 processor, standard for 2009-era compacts. CCDs are praised for color rendering and smooth tonal gradations but traditionally fall short in low-light sensitivity and noise control relative to modern CMOS sensors.

The SX730 HS advances to a 20.3MP BSI-CMOS sensor, paired with DIGIC 6 processing, a design that improves light-gathering efficiency (thanks to backside illumination), higher pixel density, and faster data handling. This contributes to a broader ISO range (native 80–3200), enhanced dynamic range potential, and quicker autofocus capabilities (contrast detection plus intelligent tracking algorithms).

In practical tests, the SX730 HS yields notably sharper images with greater detail retention, especially evident in landscape and macro photography. Edited sample photos confirm the SX730’s superior resolution and color fidelity, with less noise at higher ISO settings - critical for indoor, night, or sports scenarios where lighting is less predictable.

Furthermore, the SX730 supports multiple image aspect ratios (1:1, 4:3, 3:2, and 16:9) versus the A1100’s limited 4:3 and 16:9, offering compositional flexibility. Unfortunately, neither supports RAW, restricting post-processing latitude compared to more advanced compacts.

The Rear Screen and Interface: Evaluating Live View and Feedback

Both models exclude electronic viewfinders and rely heavily on LCD screens for live framing and review. Here, the SX730 HS again asserts a decisive advantage: a larger, tilting 3” screen with nearly 8x higher resolution (922k vs. 115k dots) and self-timer options tailored for “selfie-friendly” compositions.

The A1100 IS’s fixed screen can feel cramped and low-res - a handicap especially for reviewing sharpness or intricate scenes in the field. Canon's UI on both cameras remains user-friendly but the SX730's sharper display and modern firmware offer smoother menu navigation, faster response times, and clearer exposure readouts.

Overall, the touchscreen absence on both models forces reliance on physical buttons; the SX730 compensates with more tactile manual controls for exposure, ISO, and shooting mode, better suiting the demands of enthusiasts who want to experiment beyond automatic modes.

Autofocus and Burst Shooting: Speed and Accuracy in Dynamic Conditions

Considering autofocus performance - a decisive factor for wildlife, sports, and street photographers - the two cameras are separated by significant generational advances.

• Canon A1100 IS:

  • 9 focus points (center-weighted and contrast-detection AF)
  • Face detection enabled, but no continuous AF or tracking
  • Maximum burst rate: 1 fps

• Canon SX730 HS:

  • More advanced contrast-detection AF with face detection and real-time subject tracking
  • Supports continuous autofocus ideal for moving subjects
  • Burst rates up to 5.9 fps, expediting action capture

While neither employs phase-detection autofocus (common in DSLRs or mirrorless), the SX730’s DIGIC 6 processor and improved AF algorithms yield quicker and more reliable focusing, an important distinction for those shooting sports, wildlife, or kids in motion.

Lens and Zoom Capabilities: Field Versatility Explored

The fixed lens on both cameras defines optical reach and aperture range, profoundly affecting usability.

• A1100 IS lens: 35-140 mm (equivalent), 4x optical zoom, aperture F2.7-5.6
• SX730 HS lens: 24-960 mm equivalent, 40x optical zoom, aperture F3.3-6.9

This disparity is stark. The SX730 HS’s superzoom lens spans wide-angle to extreme telephoto lengths, enabling versatility from landscapes to distant wildlife or sports arenas without changing lenses. However, the narrower maximum aperture at the telephoto end (F6.9) means reduced low-light ability compared to the A1100’s brighter F2.7 wide end.

The A1100’s modest zoom nevertheless offers a brighter lens at the short end, advantageous for portraits or indoor scenes where depth of field control and better bokeh help isolate subjects - a typical challenge in compact cameras.

Photography Genres: Tailored Performance Insights

Having evaluated core specs and features, let’s highlight how each camera performs across diverse photo disciplines.

Portrait Photography

Portraiture demands rendering accurate, natural skin tones, smooth bokeh to isolate subjects, and reliable eye detection AF.

• A1100 IS: The wider aperture at 35mm (F2.7) permits moderately shallow depth of field, helpful for soft backgrounds in close-ups, though limited AF sophistication hampers eye detection precision. The 12MP CCD sensor delivers pleasant colors but less fine detail.
• SX730 HS: Higher resolution sensor records more detail, and face/eye detection AF is faster and more precise, boosting keeper rates in casual portraits. However, narrower max aperture at wide angles (F3.3) can make it harder to achieve creamy bokeh, and longer zooms render even shallower depth of field harder due to miniaturized sensor constraints.

Landscape Photography

Key photo criteria here include resolution, dynamic range, and weather-sealing (to protect outdoors shoots).

• The SX730 HS’s 20MP sensor records more pixel detail, which supports large prints and extensive cropping. Its better high-ISO performance and noise suppression aid dusk or dawn shots. However, note neither camera offers weather sealing, a limitation for harsh conditions.
• The A1100 IS, with older CCD technology, exhibits limited dynamic range and struggles with highlight clipping in challenging contrasts.

Effective macro depends on minimum focusing distance and stabilization.

• Surprisingly, the SX730 HS allows focusing as close as 1 cm, outperforming the A1100’s 3 cm minimum, enabling much stronger macro recording.
• Optical image stabilization on both cameras aids hand-held macro shots, but greater zoom flexibility on the SX730 also supports various framing options.

Night and Astro Photography

Critical metrics here include high ISO noise control, exposure modes, and shutter ranges.

• The SX730 HS extends ISO up to 3200, with moderate noise levels manageable in post, and shutter speeds from 15s to 1/3200s assist astrophotography.
• The A1100 IS max ISO of 1600 combined with older CCD sensor limits low-light usability; longer exposures possible but noise increases quickly.

Video Capabilities

In the era of growing hybrid shooter demands, video specs are paramount.

• A1100 IS: Limited to VGA (640x480) at 30fps, Motion JPEG codec, no microphone/jack inputs, and no image stabilization beyond optical lens correction.
• SX730 HS: Full HD 1080p at 60fps, MPEG-4/H.264 compression, optical image stabilization, and HDMI output exist, affording better-quality, smoothed video ideal for casual vloggers or content creators. However, the absence of mic input lessens pro audio capture options.

Battery Life and Storage: Shooting Duration Matters

The A1100 IS runs on two AA batteries, ensuring field-replaceable power but at some cost to sustained performance - AA alkalines provide limited frame counts, and rechargeables are advisable for extended use.

The SX730 HS uses a proprietary Lithium-ion battery rated for 250 shots per charge, more in line with modern compact standards, but less convenient for travelers without charging access.

Both cameras use single SD card slots, with the SX730 supporting SDXC for greater storage volume, an important consideration for high-resolution images and HD video.

Build Quality and Durability

Neither camera offers any weather sealing, shockproofing, or extreme condition safeguards; both are typical compact designs made of plastic and metal components, intended for casual protected use rather than rugged professional demands.
