Canon SX20 IS vs Samsung SL30: A Hands-On Comparison of Two Small Sensor Digital Cameras

When I first unpacked the Canon PowerShot SX20 IS and the Samsung SL30, I was struck by how differently these two small sensor cameras approach photography - one as a robust bridge superzoom, the other as a compact pocket-friendly shooter. Over my years testing hundreds of cameras, I’ve found comparing such distinct designs offers unique insights into what each can realistically deliver for photographers with varying needs and budgets.

In this review, I draw heavily on extensive field tests, from portrait lighting studios to windy mountain landscapes, from bustling street corners to intimate macro setups. Along with deep technical analysis, I’ll share real-world performance observations that highlight how the Canon SX20 IS and Samsung SL30 behave in daily shooting scenarios.

Let’s dig in.

At a Glance: Size, Ergonomics, and Handling

One of the first things I noticed handling these cameras is the difference in physical presence.

The Canon SX20 IS has a substantial SLR-style bridge body, measuring 128 x 88 x 87 mm and weighing a hefty 600 grams. It feels solid and well-gripped in my hands with ample room for dedicated controls.

In contrast, the Samsung SL30 is clearly designed as a pocket-sized compact, at 94 x 61 x 23 mm and only 140 grams. It slips easily into any jacket pocket but offers a minimalist control set.

My takeaway: If you prioritize comfortable handling, especially for extended shooting sessions in the field, the Canon’s ergonomic bulk is a definite plus. But if absolute portability and simplicity matter more - say, for casual travel or quick snaps - the Samsung wins hands down.

Design and Control Layout: Balancing Access and Complexity

Peeking from above shows key differences in control philosophy.

The Canon SX20 IS puts shutter speed and aperture priority modes within easy reach, along with a traditional mode dial and dedicated zoom rocker. This transparency to manual exposure and zoom is a boon for enthusiasts who want hands-on control over every shot.

The Samsung SL30, meanwhile, lacks manual exposure modes, instead relying on fully automatic settings with limited user override, visible in just an on/off flash switch and mode selection via menu. The tradeoff is simplicity but reduced creative freedom.

In my testing, this translates to the Canon being a more direct, tactile tool - perfect for photographers comfortable setting exposure on the fly. The Samsung requires more patience with menus and compromises needed to coax specific looks under tricky lighting.

Sensor and Image Quality: Beyond Megapixels

Both cameras share the same sensor size - a 1/2.3” CCD - with closely matched physical dimensions (around 28 mm² sensor area). But the Canon boasts 12 megapixels while the Samsung shoots at 10 megapixels.

Though modest by today’s standards, the Canon’s digits offer slightly better resolution, providing more detail especially noticeable in landscape and portrait crops. The CCD sensor technology imparts a pleasing color rendition, albeit with some softness compared to modern CMOS sensors.

In practical shooting, low light is the Achilles heel for both. Their native ISO ceilings of 1600 mean noise becomes evident beyond 400 ISO, especially on the Samsung which lacks image stabilization. The SX20 IS’s optical IS helps maintain sharpness in dim conditions.

A note on color and dynamic range: Neither camera can match the dynamic range or color depth seen in newer, larger-sensor models. Mid-range highlights may clip and shadows can lose detail under high contrast scenes.

Viewing the World: Screens and Viewfinders

Composition and review depend heavily on display quality and options.

The Canon SX20 IS offers a fully articulated 2.5-inch LCD screen. This is a real advantage when shooting video, macro, or tricky angles, providing flexibility to compose in awkward positions. The resolution is modest at 230k dots, sufficient but not spectacular.

Samsung’s SL30 has a fixed 2.5-inch screen with the same resolution. While adequate for simple framing, it lacks the tilting function that can greatly improve usability in creative situations.

Additionally, the Canon’s electronic viewfinder (EVF) - while low resolution and not highly detailed - gives a useful alternative to bright sunlight where LCD glare becomes a problem. The Samsung offers no viewfinder, limiting usability outdoors.

Shooting Experience Across Photography Genres

Portrait Photography

The Canon’s 20x optical zoom, ranging from 28 to 560 mm equivalent, provides excellent framing flexibility for portraits. The lens with a maximum aperture of f/2.8 at the wide end helps create pleasing background separation, although at telephoto focal lengths the f/5.7 aperture limits bokeh quality somewhat.

While Canon lacks advanced face or eye autofocus aids, its 9-point contrast-detection AF system delivers reliable focus in controlled conditions. Skin tones rendered are natural with good color balance from the DIGIC 4 processor.

Samsung’s shorter 3x zoom (38-114 mm) constrains framing options. Its smaller maximum aperture at telephoto equivalent also restricts background blur. However, it impressively offers face-detection AF, a helpful feature for casual portraits.

I found the SX20 IS better for deliberate, controlled portrait sessions, while the SL30 is more a grab-and-go casual candid tool.

Landscape Photography

For landscape shooters, resolution, dynamic range, and focal length matter.

The Canon’s higher resolution sensor provides a bit more detail for large prints or cropping flexibility. Combined with its extensive zoom range, it enables both wide vistas at 28 mm equivalent and closer detail capture at 560 mm.

Weather sealing is absent on both, meaning I was cautious shooting in rainy or dusty environments. Physically robust, the Canon’s bigger body handled outdoor shoots more comfortably.

Samsung’s compact size is great for lightweight travel but its considerably shorter zoom necessitates moving around more to frame scenes. Also, lack of image stabilization was felt when handholding longer exposures.

Wildlife and Sports Photography

These genres demand fast autofocus and quick frame rates.

The Canon SX20 IS features a contrast-based autofocus with 9 selectable points but no continuous autofocus for moving subjects. Its continuous shooting speed is a modest 1 fps, limiting action capture.

The Samsung SL30 lacks continuous shooting specs and autofocus modes specifically for tracking, making it unsuitable for fast-moving subjects.

In practical tests photographing birds and kids at play, I found the Canon’s slow burst rate and single AF mode insufficient for reliable tracking. Sports and wildlife shooters would be advised to look elsewhere.

Street and Travel Photography

Street photography calls for discretion, quick shooting, and portability.

Samsung’s SL30 excels here as a truly pocketable model - light and quiet with fast startup. Its face detection aids quick capturing of people candidly.

Canon’s larger form factor and louder zoom make it more conspicuous. However, in daytime street scenes, its versatile zoom range proved handy for spontaneous composition shifts.

For travel photography, the Canon’s robust feature list, extended zoom, and articulated screen support a broad array of subjects - from cityscapes to wildlife and macros - making it more versatile but less convenient to carry all day.

Macro Photography

The Canon’s lens enables close focusing down to zero centimeters macro (close to the front of the lens), paired with optical image stabilization, making handheld macro shots easier.

Samsung’s fixed lens macro focus limit is around 5 centimeters, decent for casual flower shots but less forgiving.

I recommend the Canon SX20 IS for dedicated macro enthusiasts who want detail and flexibility. Samsung SL30, while capable, is more an afterthought in this area.

Night and Astrophotography

Long exposures require stable support and clean high-ISO performance.

The Canon offers shutter speeds up to 1/3200s and down to 15 seconds, supporting typical night photography needs. Combined with image stabilization, it handled star field shots better, although noise remains visible beyond ISO 400.

Samsung’s maximum shutter speed is limited to 1/1500s and minimum 8 seconds, and lacks stabilization. Noise performance was visibly worse, making it unsuitable for demanding low light work.

Video Capabilities

Video recording on these cameras reflects their era and class.

Canon’s SX20 IS supports HD video at 1280x720 resolution at 30 fps with H.264 compression. The articulating screen is great for video framing. However, there’s no external mic input, limiting audio quality upgrades.

Samsung SL30 records lower resolution VGA video maxing at 640x480, using Motion JPEG format. No optical stabilization or video aids reduce quality.

For casual video, Canon is the clear winner though neither meets modern advanced videography standards.

Technical Deep Dive

Autofocus System

Both rely on contrast-detection autofocus, but Canon offers 9 focus points versus Samsung’s unspecified. Canon’s AF is slower but more versatile; the Samsung’s face detection is notable for its time but lacks fine control.

Build Quality and Durability

Neither camera offers weather sealing. Canon’s bulk affords better durability and heat dissipation. Samsung’s plastic compact chassis feels lightweight but less rugged.
