A Thorough Comparison Between the Samsung SL820 and Sony NEX-5T: What Photographers Should Know

When we dive into camera comparisons, especially between models that sit in very different categories, the devil is in the details - and the use case. Today, we’re rolling up our sleeves to unpack and juxtapose two distinct photographic tools: the Samsung SL820, a compact camera from 2009 designed for casual shooting, and the Sony Alpha NEX-5T, a more sophisticated entry-level mirrorless from 2013 that broke new ground in its class. Each camera tells a different story, serving different users, budgets, and photographic ambitions.

Having personally handled thousands of cameras over my 15+ years testing and reviewing, I aim to deliver real-world, hands-on insights that cut through marketing fluff and strictly technical spec sheets. If you’re a photographer evaluating these cameras side-by-side, read on for a detailed, practical, and honest perspective.

Size, Handling, and Design: Portability Versus Control

First impressions matter. The Samsung SL820 is a typical small-sensor compact, while the Sony NEX-5T strides into the mirrorless arena with interchangeable lenses and more physical presence.

The SL820’s dimensions (95 x 59 x 23 mm) and weight (168 g) make it pocketable, ideal for moments when you want a lightweight snappy shooter. It’s closest to a “grab and go” companion for casual photography or travel days when minimalism is key.

By contrast, the Sony NEX-5T is bulkier and heavier at 111 x 59 x 39 mm and 276 g, mainly because of its larger body, dedicated grip, and interchangeable lens mount. Nevertheless, it remains one of the more compact APS-C mirrorless cameras of its time and balances ergonomics with portability quite well.

Looking at the top panel, the SL820 offers minimal physical control options, no dedicated dials for exposure modes, and an integrated flash. The NEX-5T, however, features a hot shoe for external flashes, physical buttons for shooting modes and exposure compensation, and a dedicated shutter speed dial. This makes the Sony a better choice for photographers who crave quick manual control and customization in the field.

Sensor Technology and Image Quality: The Heart of the Matter

This is where these two cameras begin to diverge sharply and why the NEX-5T commands a significantly different user profile.

The Samsung SL820 employs a small 1/2.3” CCD sensor measuring 6.08x4.56 mm with a total area of about 27.7 mm². The 12-megapixel resolution outpaces many compact cameras of its era but is limited by the sensor size’s inherent noise performance and dynamic range challenges. Its CCD construction generally yields good color rendition at base ISO but struggles at higher sensitivities beyond ISO 400–800.

On the other hand, the Sony NEX-5T sports a significantly larger APS-C CMOS sensor of 23.4 x 15.6 mm totaling 365 mm² - nearly 13 times the area of the SL820’s sensor. It’s coupled with Sony’s Bionz image processor to deliver 16-megapixel images with excellent dynamic range and color depth, making it suitable for demanding scenarios like landscape and portrait work.

Sony’s sensor allows for a much broader ISO range (100–25600 native), which tangibly improves low-light performance, an area where the smaller-sensor SL820’s native ISO tops out at 1600 with noticeable noise at anything above ISO 400.

In testing, landscapes and detailed subjects captured on the NEX-5T show clean textures, fine detail retention, and minimal noise, even without heavy noise reduction. The SL820, compared side-by-side, reveals more muted tonality, less sharpness, and blotchy noise patterns once ISO climbs past 400. Portraiture benefits greatly from the larger sensor’s natural ability to deliver better tonal gradation.

Viewing Experience and User Interface: The Photographer’s Window

Handling and framing shots in the field depends heavily on viewfinder and screen quality. Both cameras forego optical viewfinders, but how they approach this differs.

The Samsung has a fixed 3" screen at a comparatively low 230K-dot resolution. It simply displays the scene and menus well enough for casual use but falls short on clarity and brightness, particularly under strong daylight.

The Sony NEX-5T upgrades with a tilting 3" TFT LCD screen featuring 922K-dot resolution and touchscreen capability, a big leap forward for composition versatility and menu navigation. The tilt functionality allows shooting from awkward perspectives - low down, over the head, or even as a handy selfie screen. The touchscreen simplifies autofocus point selection and quick function access.

While the NEX-5T lacks a built-in electronic viewfinder by default, it supports an optional accessory EVF - a noteworthy option for bright outdoor shooting and precise focusing if you can invest further.

Autofocus Systems and Performance: Precision and Speed in Real Conditions

Autofocus can make or break the experience, especially when shooting dynamic subjects such as wildlife or sports.

The SL820 relies solely on contrast-detection autofocus with a center-weighted area and face detection. This, combined with the relatively slow 2009-era processor, results in noticeable lag and hunting, especially in low light. There’s no continuous AF or tracking mode, which restricts the camera to static scenes or posed shots for best results.

Sony’s NEX-5T excels here, packed with 99 autofocus points - 25 cross-type PDAF points embedded on sensor - and leverages hybrid AF (phase + contrast detection) for speed and accuracy. Real-world testing shows the NEX-5T could track moving subjects reliably, with bursts up to 10 frames per second, making it a good entry-level choice for amateur sports and wildlife photographers on a budget.

While neither camera supports animal eye detection (newer AF features coming later in the decade), the NEX-5T’s face detection and tracking AF are effective for portraits and street photography, keeping focus locked on subjects with better consistency.

Lens Ecosystem and Optical Capabilities: Fixed Versus Interchangeable

In the lens department, the Samsung SL820 comes equipped with a fixed 28-140mm equivalent lens (5x zoom), aperture ranging from f/3.4 to f/5.8. This lens covers the most commonly used fields of view but carries inherent compromises - softness toward the edges at longer focal lengths, limited low-light performance, and a lack of depth of field control for strong bokeh effects.

In contrast, the Sony NEX-5T utilizes the Sony E-mount, giving access to an expansive range of lenses, even today. From fast primes like the 50mm f/1.8 for portraits to super-telephoto zooms suited for wildlife, the NEX system benefits from a healthy and varied ecosystem. Even in 2013, users had 121 lenses to choose from, giving creative freedom and precision optics choices.

This flexibility means that with the NEX-5T, you are not locked to a compromising zoom lens but can tailor your optical toolkit to the genre: macro, landscape, sports telephoto, or cinematic primes. This directly impacts image quality potential and user satisfaction.

Battery Life and Storage: Practical Considerations for Extended Use

Neither camera is perfect when it comes to battery endurance, but their designs reflect their eras and intended uses.

The SL820 uses the SLB-10A battery, with no published battery life but generally aligns with the compact camera norm of around 200–300 shots per charge, depending on usage. Its lack of wireless features or live view autofocus tracking mitigates power drain somewhat.

The Sony NEX-5T, meanwhile, benefits from a more efficient battery pack (NP-FW50) rated for about 330 shots per charge. More importantly, the larger body houses space for better battery management, making extended shooting days more feasible. However, using Wi-Fi and touchscreen controls will impact actual longevity.

Storage-wise, the SL820 supports SD/SDHC cards and MMC formats, while the NEX-5T supports SD/SDHC/SDXC cards in addition to Sony’s proprietary Memory Stick Pro cards - useful for backup options and expanding capacity.

Video Capabilities: From Modest to Versatile

Video recording capabilities highlight the technology gap further.

The SL820 offers HD video at a maximum of 1280x720 pixels at 30 fps using Motion JPEG codec - functional for casual video snippets but limited by resolution, codec inefficiency, and no microphone input.

The NEX-5T delivers full 1080p HD video at higher frame rates (60p/60i/24p) encoded in MPEG-4, AVCHD, and H.264 formats. This is a key benefit for enthusiasts interested in video, affording cinematic frame rates and better compression for manageable file sizes without sacrificing quality. The absence of a microphone port limits advanced audio options, but the video quality and manual exposure controls afford much more creative flexibility than the SL820.

Real-World Photography Scenarios: Practical Usability in Different Genres

Now, let’s contextualize these specs and features in the photographic disciplines where they matter most.

Portrait Photography

The SL820’s small sensor limits shallow depth of field effects - portraits won’t have that creamy bokeh separation that larger sensors and fast lenses provide. Face detection is available to help focus, but color profile and noise performance are average.

Contrastingly, the NEX-5T with its APS-C sensor excels here. Shallow depth of field from fast E-mount lenses with wide apertures renders skin tones delicately and punches up subject-background separation beautifully. Its face detection autofocus locks quickly and accurately, ensuring crisp eyes in portraits.

Landscape Photography

Landscape shooters value dynamic range and resolution. The SL820’s sensor puts up a fight but displays compressed tonal variation, especially in highlights.

The NEX-5T provides superior dynamic range (~13 EV on DxO Mark) and higher detail resolution at 16MP, capturing vast scenes with subtle shadows and bright highlights intact. Though neither offers environmental sealing, the NEX-5T can be paired with weather-sealed lenses for better outdoor ruggedness.

Wildlife and Sports Photography

SL820’s slow AF and limited burst shooting don’t meet the demands of fast-paced wildlife or sports.

NEX-5T’s 10 fps continuous shooting and hybrid AF system offer competent performance for beginners venturing into these genres, provided you work with appropriate telephoto glass.

Street Photography

The compact SL820 scores points with discretion and portability - quiet operation with minimal bulk is a street shooter’s friend. Its limits lie in low-light IQ.

The NEX-5T is still small enough for street shooting and offers superior low-light sensitivity and faster responsiveness. The tilting screen helps with candid angles, although it demands carrying lenses.
