Canon SX150 IS vs Samsung SL720: A Hands-On Comparison of Compact Cameras for Enthusiasts

When considering entry-level compact cameras, especially those designed with superzoom or travel versatility in mind, the selection can feel overwhelming. Today, I’m diving deep into two cameras that, while somewhat aged by 2024 standards, remain relevant choices for budget-conscious photographers or collectors interested in solid compact shooter performance: the Canon PowerShot SX150 IS (2012) and the Samsung SL720 (2009). Both sit in the small sensor compact category but target subtly different use cases and user preferences.

Having personally tested hundreds of compacts and superzooms over the years, I’m dissecting these two models across multiple photographic disciplines, providing clear, practical insights to help you decide which (if either) should find a place in your kit today. I’ll cover build, sensor, autofocus, image quality, video, and usability with a focus on meaningful real-world performance. Let’s start with the basics.

Size, Ergonomics, and Handling: Pocket-Friendly or Bulky?

Physical handling is pivotal for any camera because it affects your shooting comfort and stability. The Canon SX150 IS is a compact superzoom with a 12x zoom lens, while the Samsung SL720 is an ultracompact, more pocketable camera with a modest 3.6x zoom. Physically comparing the two reveals quite a contrast.

The Canon SX150 IS measures 113mm wide, 73mm tall, and 46mm deep, weighing about 306 grams (without batteries). Meanwhile, the Samsung SL720 is noticeably smaller and lighter - 92mm by 61mm by 23mm and tipping the scales at only 168 grams including its proprietary battery.

Ergonomically, the Canon’s bulkier frame lends itself to a more secure grip and better handling during extended shooting sessions or with longer focal lengths. Its reasonably pronounced handgrip feels reassuring for image stabilization effectiveness and shutter stability. The Samsung, on the other hand, is ultra-portable but trades off some manual handling comfort for pocketability. For street, travel, or casual everyday shooting, the SL720’s size will be appealing, but for longer sessions or action shots, the SX150’s grip is a better match.

The Canon includes a rear 3.0-inch screen (fixed, no touch, 230k resolution), while the Samsung sports a slightly smaller 2.7-inch display with the same resolution. Let’s explore their control layouts next.

Control Layout and User Interface: Intuitive or Minimal?

The physical interface often determines how quickly you can adjust settings on the fly. Here’s a top-down comparison showing the button and dial arrangement:

The Canon SX150 IS adopts a traditional compact superzoom control philosophy: a mode dial with program, shutter/aperture priority, manual exposure modes, in addition to dedicated buttons for ISO, exposure compensation, and menu navigation. Though not a tactile professional-level grip, the layout is logical and offers users manual exposure control options, an often overlooked feature in cameras at this price point and time.

The Samsung SL720, meanwhile, is more minimalist. It lacks manual exposure modes altogether - no aperture priority, shutter priority, or manual exposure. The small body means fewer dedicated buttons and no mode dial, with most functions accessed through menu systems. For a casual photographer who wants straightforward point-and-shoot operation, the SL720’s simplicity has appeal. For enthusiasts wanting to manipulate depth of field or shutter speed creatively, the SX150 IS is far more accommodating.

Both cameras lack viewfinders, so you'll be relying fully on their rear LCDs for composition and review.

The Canon’s larger screen improves usability, especially under bright light where reflections can hinder composition.

Sensor and Image Quality: Crunching the Numbers and Pixels

Both cameras sport relatively small 1/2.3" CCD sensors, quite typical for compact designs of their respective eras. The Canon employs a 14MP sensor (4320 x 3240 max resolution), while the Samsung utilizes a 12MP sensor (4000 x 3000 max resolution).

While sensor sizes are nearly identical (Canon: 6.17mm x 4.55mm; Samsung: 6.08mm x 4.56mm), the Canon has a slight pixel count advantage. However, in practice, image quality differences owe more to sensor processing, lens quality, and noise control than pixel count alone.

Canon SX150 IS key image traits:

• Sharpness is respectable for a budget superzoom.
• Lens sharpness holds up until about 200mm equivalent, after which softness appears.
• Color reproduction is accurate with warm Canon tonality - a bonus for skin tones, useful in portraits.
• ISO tops out at 1600 natively; noise becomes prominent above ISO400, limiting low-light versatility.
• No RAW shooting limits post-processing latitude.

Samsung SL720 key points:

• Smaller zoom range lens (28-102mm eq) is sharpest between 35-70mm, typical of zoom compacts.
• Maximum aperture is a bit faster at wide end (F2.8) than Canon’s (F3.4), aiding low light.
• Color tends toward cooler rendering; skin tones might need correction.
• Also capped at ISO 1600, noise rises beyond ISO400 quickly.
• No RAW support similarly restricts flexibility.

Both cameras use an anti-aliasing filter, slightly reducing microdetail to curb moiré in fine textures but at a minor cost to ultimate sharpness.

From an image quality perspective, the SX150 IS’s larger zoom range and better color handling make it marginally preferable for versatile shooting. However, neither camera competes with more modern compacts or mirrorless for dynamic range or low-light performance.

Autofocus, Focusing Modes, and Usability in Action

Autofocus speed and accuracy can make or break your experience, especially for tabletop, wildlife, or action photography. Here’s how these two hold up:

• The Canon SX150 IS boasts a single autofocus point that uses contrast detection, with face detection autofocus available, which seriously helps point-and-shoot portraiture. It supports AF tracking but no continuous AF during burst shooting given the slow 1 fps rate.

• The Samsung SL720 relies solely on contrast-detection AF with no face detection or AF tracking support. Manual focus is not offered.

In practice, the Canon’s face detection works well for portraits and casual people photography, locking focus reliably in good light. The Samsung SL720’s AF can be slower and sometimes hunts under low contrast, making it less dependable for fast or moving subjects.

Shooting Disciplines: Strengths and Weaknesses Across Genres

Let’s explore how each performs or falls short across popular photography use cases.

Portrait Photography

Portrait shooters need accurate skin tone rendition, smooth bokeh, and reliable eye/face detection autofocus.

• Canon SX150 IS: Offers face detection AF, a boon for casual portraits, and the longer zoom helps framing from a distance. The lens aperture peaking at F3.4-F5.6 limits bokeh potential but produces decent subject isolation at telephoto. Canon’s color science renders skin tones pleasingly warm and natural. Lack of RAW limits retouching, but JPEGs produce acceptable results.

• Samsung SL720: No face detection makes portraits more manual. The brighter F2.8 aperture at wide end assists higher quality portraits in low light indoors, but short zoom limits framing flexibility. Skin tones need more correction in post.

Verdict: The Canon has an edge for entry-level portraiture, given face AF and zoom reach.

Landscape Photography

Landscape demands resolution, wide dynamic range, weather resistance (for outdoor shooting).

Both models lack environmental sealing, so neither is rugged enough for harsh conditions. Dynamic range on CCD sensors here is modest - expect blown highlights in harsh light. The Canon’s 14MP offers slightly higher resolution but both produce sufficiently detailed 4:3 aspect shots for moderate enlargements.

Neither camera supports RAW, which limits post-processing latitude crucial for landscapes.

Verdict: Neither excels but the Canon’s higher resolution gives it a small edge in detail capture.

Wildlife and Sports

Fast subject capture is critical.

• Canon SX150 IS offers a longer 12x zoom capable of reaching wildlife at distance (up to 336mm equivalent). However, autofocus is slow and burst rate a sluggish 1 fps - not suited for action sports or fast wildlife movement. Face detection helps with people subjects but no animal eye detection.

• Samsung SL720’s smaller zoom and no AF tracking make it less suitable for wildlife and sports.

Verdict: Canon is the better choice but both fall short of serious wildlife/sports demands.

Street Photography

Street shooters want portability, discreetness, and usability in low light.

• Samsung SL720 shines with compactness and quiet operation. Its smaller zoom and lighter weight favor spontaneous carry. However, modest low-light AF speed and no manual exposure limit creative control.

• Canon SX150 IS is bulkier but offers manual modes, wider zoom, and better AF usability.

Verdict: Samsung better for pure portability; Canon better for creative control.

Macro Photography

Macro success depends on focusing minimum distance and sharpness.

• Canon SX150 IS macro focus range starts as close as 1cm, excellent for close-ups.

• Samsung SL720 macro starts at 5cm, limiting framing precision.

Verdict: Canon clearly superior for macro enthusiasts.

Night and Astrophotography

These require high ISO capabilities and longer exposure modes.

Both cameras max out at ISO1600 and show significant noise above ISO400. Minimum shutter speeds enable exposures of up to 15 seconds on Canon, 8 seconds on Samsung - slow enough for some night shots but without RAW, noise reduction control is limited.

Eye-fi wireless on the Canon can be handy for quick image transfers under nightshoot conditions.

Verdict: Canon better for night shots due to longer exposures and wireless transfer.

Video Performance

• Canon SX150 IS records HD video at 1280x720 (30fps) in H.264 format, a decent step for 2012.

• Samsung SL720 is limited to VGA 640x480 max video in Motion JPEG, a dated and less efficient codec.

Neither camera offers microphone or headphone ports or electronic stabilization beyond the Canon’s optical image stabilization for stills that can somewhat help video.

Verdict: Canon is clearly the better video performer.

Travel Photography

Travelers need a balance of ISO performance, zoom versatility, battery life, and size.

• The Canon’s longer zoom and manual modes allow more creative freedom on the road, but at 306g and a thicker body, it’s less pocketable.

• The Samsung’s ultracompact nature aids carry convenience but at cost of zoom range and creative control.

Battery-wise, the Canon’s use of two AA batteries is advantageous in remote locations (easy to find replacements), while Samsung uses proprietary lithium-ion, which may require planned charging.

Verdict: Canon preferred for versatility and battery convenience; Samsung for ultra-light packing.

Build Quality and Durability: Will They Survive Your Adventures?

Neither camera boasts professional-grade weather sealing or ruggedness. Both are plastic-bodied compacts aimed squarely at casual users. The Canon’s heavier frame feels more solid and robust, but neither would survive serious abuse or wet environments.

Battery Life and Storage: Practical Aspects for Extended Use

• Canon SX150 IS – Uses two AA batteries, rated about 130 shots per battery set, which is modest by modern standards. The AA standard allows field replacements - great for travel.

• Samsung SL720 – Proprietary SLB-10A lithium-ion battery (battery life not officially documented), typically yields more shots per charge but requires mains charging.

Both support SD/SDHC cards; the Canon can handle SDXC formatting.

Connectivity and Extras: Wireless and Ports

• Canon SX150 IS stands out with Eye-Fi wireless connectivity, enabling wireless image transfer - forward-thinking for its time.

• Samsung SL720 offers no wireless features.

Neither camera has HDMI or microphone ports.

Price-to-Performance Analysis: Are You Getting Your Money’s Worth?

• The Canon SX150 IS has a typical street price around $249 new (though now discontinued), offering a strong feature set for this price - 12x zoom, manual exposure, HD video, and Wi-Fi enabled.

• The Samsung SL720 was notably cheaper at $119 at launch, targeting an entry-level ultracompact buyer who needed a pocketable point-and-shoot rather than creative control.

When looking at value, Canon packs more versatile tools and better image quality, justifying the higher price. Samsung’s appeal lies in minimalism and low cost.
