Samsung SL620 vs Sony Cyber-shot WX9: In-Depth Comparison of Two Ultracompact Cameras

Choosing an ultracompact camera in today’s crowded market is a challenge - especially when two models target similar users but take fundamentally different technical approaches. The Samsung SL620 and Sony Cyber-shot WX9, released about two years apart, represent two snapshots of compact camera evolution, each with unique strengths and compromises. Having spent many hours testing and comparing these cameras side-by-side, I’m ready to share practical, experience-backed insights to help enthusiasts and professionals determine which suits your photography needs.

Let’s dive into their technical foundations, real-world use cases, and performance across diverse photography disciplines to uncover where each model shines - and where you need to adjust your expectations.

First Impressions: Size, Build, and Handling

When I picked up the Samsung SL620 and Sony WX9 back-to-back, the physical differences were instantly noticeable, despite their similar ultracompact intentions.

The SL620 measures 92x61x23 mm and weighs a mere 168 grams, making it exceptionally pocketable and light. The WX9, slightly larger at 95x56x20 mm, feels a bit more substantial but retains excellent portability. The WX9’s slimmer profile compensates somewhat for its slightly larger footprint. Neither camera offers a very deep grip, but the WX9’s rounded edges and slightly contoured back feel more comfortable for extended handheld shooting.

Both lack dedicated viewfinders or advanced controls due to their compactness, but in terms of handling, the WX9 feels more solidly-built despite not featuring any weather sealing - not surprising given their price and target market. The SL620’s plastic chassis feels less refined, which may disappoint shooters expecting a more durable package.

Overall, if ultimate pocketability matters most, the SL620 edges the WX9 by a slim margin. But the WX9’s ergonomic refinements make it more comfortable for sustained shooting sessions.

Design and User Interface: Control Layout and Screen Quality

Delving deeper, the control surfaces and rear displays significantly impact daily usability - especially for fast-moving or creative work. I compared both cameras’ design philosophies by looking at their top plates and back screens.

The WX9 sports a slightly larger 3.0-inch XtraFine LCD with 921k dots, a serious upgrade over the SL620’s smaller 2.7-inch display with just 230k dots. This difference in resolution makes a meaningful impact when reviewing images or navigating menus - the WX9’s screen provides sharper detail and more accurate color rendition.

Neither camera has touchscreens or viewfinders, so the LCD is your only framing and playback option. The WX9 also includes more illuminated button markings, aiding quick identification in dim conditions.

Control-wise, both cameras opt for simple button layouts without dedicated dials for aperture or shutter priority. Sony’s inclusion of continuous shooting mode accessible through a dedicated button allows quicker frame bursts, whereas Samsung’s SL620 does not offer continuous shooting at all. This can be a dealbreaker for users capturing fast action.

In summation: The WX9 leads with a superior rear screen, more responsive controls, and an edge in usability for motion photography.

Sensor Technology and Image Quality: The Heart of the Matter

Let’s get technical and analyze the sensors behind each camera - one of the most crucial factors defining final image quality.

Both cameras employ the standard 1/2.3-inch sensor format common in ultracompacts, but that’s where the similarity ends.

• Samsung SL620: Utilizes a 12-megapixel CCD sensor without RAW support.
• Sony WX9: Features a more modern 16-megapixel BSI CMOS sensor with anti-aliasing filter and no RAW output.

The WX9’s back-illuminated sensor design improves light gathering efficiency and reduces noise, which is visible even at base ISO settings compared to the SL620’s CCD. This translates to cleaner, sharper images, especially in challenging lighting.

Both sensors max out native ISO at 1600 (SL620) and 3200 (WX9), but in practice, Sony’s WX9 produces usable images at ISO 800 and sometimes beyond, whereas the SL620’s images show noticeable noise and softer detail from 400 ISO upwards.

Resolution-wise, the WX9’s 16 MP sensor offers higher pixel counts - 4608x3456 vs 4000x3000 for SL620 - leading to slightly improved print potential and cropping flexibility.

In addition, Sony supports multiple aspect ratios (4:3, 16:9), giving photographers more framing options, while Samsung sticks to 4:3 standard.

Taken together, the WX9’s sensor is considerably more capable and modern, making it better suited for all photography genres that benefit from high image quality.

Handling Different Portrait Photography Challenges

Portrait photographers must pay attention to skin tones, bokeh rendition, and reliable autofocus on faces and eyes. How do these cameras stack up?

The SL620 offers contrast-detection autofocus with face detection capability. It can accurately lock onto faces but lacks any specialized eye autofocus, which wasn’t common in ultracompacts of its era. Its fixed lens offers a 35-175 mm zoom (full-frame equivalent), but aperture ranges from f/2.8-5.7 are only moderately fast - adequate for usual lighting but limiting indoor work.

The WX9’s autofocus system is updated with 9 contrast-detection points (versus unspecified on the SL620). However, it lacks face or eye detection, forcing users to rely on center or multi-area AF modes. Its lens offers a wider zoom range of 25-125 mm at f/2.6-6.3 aperture. The slightly wider wide-angle end is great for environmental portraits.

Regarding bokeh, neither camera has particularly large sensors or bright lenses to produce pronounced background blur. The WX9’s slightly narrower aperture at telephoto (f/6.3 vs SL620’s f/5.7) results in less bokeh potential.

That said, I found the WX9’s higher resolution sensor delivers more natural skin texture reproduction, whereas the CCD sensor of the SL620 leans toward slightly warmer but flatter skin tones under artificial lighting.

Bottom line:

• For casual portraits in good light, either is acceptable.
• The WX9’s better sensor and wider angle are advantageous for environmental portraits.
• SL620 may appeal if warmer tones suit your style but suffers under low light.
• Neither excels at subject tracking or eye autofocus.

Landscape Photography: Dynamic Range, Resolution, and Shooting Conditions

Landscape demands high resolution, expansive dynamic range, and preferably some weather resistance.

Neither camera offers weather sealing or environmental protection - a notable omission for dedicated landscape work in unpredictable conditions.

Resolution-wise, the WX9’s 16 MP sensor grants marginally better detail for landscape prints and cropping. The BSI-CMOS sensor’s improved dynamic range helps preserve highlight and shadow detail, which is crucial for landscape scenes.

The SL620’s CCD sensor delivers acceptable dynamic range but trails the WX9 in recoverability during post-processing. The lack of RAW mode on both cameras requires close work with JPEG output, and Sony’s sensor processing in JPEG mode is cleaner and more faithful.

Macro capabilities are close, both supporting focus down to 5 cm, allowing detailed close-ups of flora and small landscape features.

In my field tests, the WX9 consistently recorded more vibrant, true-to-life colors outdoors, with better shadow detail and less noise in shaded areas compared to the SL620.

If landscape photography is your focus:

• Choose the WX9 for improved dynamic range and resolution.
• Lack of weather sealing means careful handling outdoors.
• Consider external UV filters and tripod use to maximize sharpness and protection.

Capturing Fast Action: Wildlife and Sports

Wildlife and sports photography demand rapid autofocus, high burst frame rates, and effective telephoto zooms.

• The SL620 offers a 5x optical zoom lens (35-175mm full-frame eq.) - not exceptionally long but suitable for casual telephoto needs.
• Sony WX9’s 5x zoom (25-125mm eq.) starts wider but does not reach as far telephoto as the SL620.

Autofocus systems lack sophistication on both; neither supports phase detection or advanced tracking modes. The WX9’s 9 contrast detect points provide some coverage but without continuous AF tracking or eye AF for animals or athletes.

Importantly, the WX9 supports a continuous shooting speed of 10 frames per second, a significant advantage for capturing fast sequences, though buffer depth and autofocus consistency limit practical bursts. The SL620 does not offer continuous shooting, restricting its utility for action.

Built-in optical image stabilization on the WX9 helps reduce motion blur during telephoto handheld shots, making a tangible difference when shooting moving subjects, while the SL620 has no stabilization, increasing the chance of blurry shots in these scenarios.

In my trials photographing birds in motion and casual sports, the WX9 reliably nailed focus faster and allowed better freeze-frame captures, while the SL620 could miss focus and produced more motion blur.

Recommendation:

• For casual wildlife/sports, the WX9’s faster shooting and stabilization are real benefits.
• Serious telephoto needs fall outside of both cameras’ capabilities due to focal length limits.
• SL620 is least suited for dynamic shooting.

Street and Travel Photography: Portability Meets Performance

I’ve always championed ultracompacts as ideal travel companions for their convenience and casual street capture ability.

Between these two, the SL620’s smaller size and lighter weight make it a less intrusive pocket camera; however, the WX9’s sharper LCD and superior low-light performance enhance street shooting versatility.

Low-light capability is particularly pertinent here: The WX9’s sensor handles ISO 800 and 1600 much better, enabling usable night shots without a flash - a priceless asset for street photography after dark. Meanwhile, the SL620’s performance rapidly degrades above ISO 400.

Neither camera offers Wi-Fi or Bluetooth for instant image sharing, though the WX9 is Eye-Fi compatible, allowing wireless transfers with compatible cards - a modest plus for traveling photographers.

Battery life is another practical consideration: While exact numbers vary, the WX9’s NP-BN1 lithium-ion battery (common to Sony compacts) is generally more power-efficient than the unspecified battery in the SL620, meaning longer shooting per charge.

For travelers, camera weight and ease of use matter - the SL620 scores here; for image quality and usability, the WX9 pulls ahead.

Night and Astro Photography Potential

Shooting in extremely low light or night skies is a demanding discipline. Neither camera is designed for astrophotography, but evaluating noise and exposure options offers insights.

The WX9’s BSI CMOS sensor extends native ISO to 3200, and although noise grows at higher ISOs, it still produces reasonable quality JPEGs at ISO 800 and 1600 with noise reduction applied. Its slowest shutter speed is 2 seconds, allowing decent long exposure work for static subjects like landscapes or cityscapes, though 2 seconds is short for deep-sky astrophotography.

The SL620 allows a slower shutter speed down to 8 seconds, which seems promising, but its CCD sensor coupled with absence of image stabilization renders such shots vulnerable to noise and blur unless used on a stable tripod.

Neither camera supports RAW, which is a big limitation for processing night images to recover detail. Without RAW, the WX9’s cleaner JPEG processing offers a real advantage.

For timelapse or star trails, the lack of interval shooting functionality restricts creative astro use, especially on the WX9.

Macro Photography: Detail and Focusing Close-Up

I tested both cameras’ macro performance on flowers and small objects.

Both focus down to around 5 cm minimum, which is respectable for ultracompacts.

The WX9’s higher resolution sensor captures finer detail and the optical stabilization aids sharper handheld close-ups. Its XtraFine LCD helps compose intricate scenes with confidence.

Samsung’s SL620, lacking image stabilization and featuring a lower-res display, makes precise manual framing trickier, but its lens aperture helps maintain decent depth of focus for macro subjects.

Autofocus performance at close range is similar, relying on contrast detection, so focusing times are average.

For amateur macro enthusiasts, the WX9’s image quality and stabilization make it my favorite choice here.

Video Capabilities: Moving Pictures Matter

Video recording specs reveal stark contrasts.

• Samsung SL620: Offers basic video recording only at 640x480 resolution at 30 fps (maximum), with Motion JPEG format. No HD support, no microphone input, and generally poor quality by modern standards.
• Sony WX9: Records Full HD 1920x1080 at 60 fps plus 720p and lower resolutions, encoded in MPEG-4 and AVCHD formats. HDMI output enables viewing on external monitors.

The WX9 also integrates optical image stabilization during video capture, delivering smoother footage - a stark improvement over the SL620, which has no stabilization at all.

Audio is recorded via built-in microphones on both; neither supports external mic or headphone ports, limiting professional video work.

If video is even a modest priority, the WX9’s vastly superior specs, frame rates, and stabilization make it the clear choice.

Professional Considerations: Workflow and Reliability

Both models lack manual exposure control modes (no shutter or aperture priority), RAW image capture, and robust weather sealing. This strongly limits their consideration as professional tools.

Sony’s imaging pipeline and lens quality deliver more consistent outputs, which can integrate fairly well into casual workflows, especially JPEG-based.

Samsung’s model remains designed as a simple point-and-shoot for consumers, lacking key pro workflows such as tethering, bracketing, or fine white balance control.

Connectivity-wise, neither camera nor app ecosystem supports modern wireless features like Bluetooth or Wi-Fi, save for limited Eye-Fi card compatibility with the WX9.

Storage support varies - Samsung uses SD/SDHC/SDMMC, Sony supports SD/SDHC/SDXC plus proprietary Memory Stick Duo formats, providing more flexibility.

Battery and Storage Insights

While battery data for the SL620 is unspecified, the WX9 uses an NP-BN1 lithium-ion pack, a reliable, standard choice with moderate capacity.

In practice, I found Sony’s efficient processor contributes to longer shooting sessions and faster charging.

Storage-wise, the WX9’s broader card compatibility (SDXC and Sony Memory Sticks) offers more options, but there's only a single storage slot on each camera.
