Samsung HZ15W vs Sony SLT-A55: In-Depth Comparison for Photography Enthusiasts

Choosing the right camera can transform your photography experience, whether you are starting out or aiming to elevate your craft. Today, we compare two distinctly different cameras: the Samsung HZ15W, a small sensor compact camera launched in early 2009, and the Sony SLT-A55, a pioneering entry-level DSLR introduced in 2010. While both claim to cater to enthusiasts, their design philosophies, sensor technologies, and capabilities span vastly different ends of the photographic spectrum.

As seasoned reviewers with hands-on testing of thousands of cameras, we will dissect these models across features, image quality, ergonomics, and suitability for various types of photography. Our goal is to help you make an informed choice that aligns with your creative goals and shooting style.

Size, Build, and Ergonomics - How They Feel in Your Hands

Before we dive into specs and image quality, let's focus on how these cameras handle in real situations.

Samsung HZ15W vs Sony A55 size comparison

The Samsung HZ15W is a true point-and-shoot compact. Its modest dimensions - 105 x 61 x 37 mm - and light weight at just 249 grams make it pocketable and perfect for casual travel or street photography when discretion and portability are priorities. Its fixed lens with a 10x zoom range (24-240mm equivalent) gives you versatility without lens changes.

In contrast, the Sony A55 is more robust at 124 x 92 x 85 mm and 500 grams - a compact SLR-style body with a solid handgrip. It features a traditional DSLR layout with interchangeable lenses and a sturdier construction, offering more control but at the expense of compactness.

Samsung HZ15W vs Sony A55 top view buttons comparison

Sony's layout includes dedicated exposure dials, customizable buttons, and an electronic viewfinder. Samsung’s minimalist interface leans on simplicity but lacks advanced control dials or a viewfinder.

Ergonomics takeaway:

  • Choose Samsung HZ15W if lightweight, easy handling, and pocketability are critical.
  • Choose Sony A55 if you want manual controls at your fingertips and a comfortable grip for extended shooting sessions.

Sensor Technology and Image Quality - The Heart of Your Photos

The sensor defines the camera’s ability to capture detail, dynamic range, and perform well in low light - all critical for serious photography.

Samsung HZ15W vs Sony A55 sensor size comparison

Feature Samsung HZ15W Sony SLT-A55
Sensor Type CCD CMOS
Sensor Size 1/2.3" (6.08 x 4.56 mm) APS-C (23.5 x 15.6 mm)
Sensor Area 27.72 mm² 366.6 mm²
Resolution 12 MP (4000 x 3000) 16 MP (4912 x 3264)
Max ISO 3200 12800 native, 25600 expanded
Antialias Filter Yes Yes
RAW Support No Yes

The Sony A55’s APS-C sensor is approximately 13x larger in area than Samsung’s 1/2.3" sensor. Sensor size dramatically impacts image quality, noise handling, and depth of field control. The A55’s CMOS sensor delivers sharper, cleaner images with superior dynamic range (DxOmark scores of 73 overall with 12.4 EV dynamic range) compared to Samsung’s compact CCD sensor, which was never tested by DxO but is generally limited in image quality.

CCD sensors like Samsung’s excel in good light but struggle at higher ISOs with noticeable noise and detail loss. The Sony’s higher ISO capability (up to 12800 native) enables low-light shooting with less noise, essential for night, event, or indoor photography.

Image quality and sensor notes:

  • You will get better sharpness, color depth, and noise control from the Sony A55, especially in challenging light.
  • The Samsung HZ15W suffices for casual snapshots with more limited expectations regarding image editing or large prints.

Display and Viewfinder - Composing Shots Your Way

Both cameras have 3" LCDs but differ greatly in resolution and flexibility.

Samsung HZ15W vs Sony A55 Screen and Viewfinder comparison

The Sony A55 boasts a fully articulated screen with 921k-dot resolution, ideal for shooting at odd angles, video framing, or vlogging. It also offers a bright electronic viewfinder with 1150k-dot resolution providing eye-level composition, an advantage in bright sunlight when LCDs are hard to see.

The Samsung HZ15W sports a fixed 460k-dot LCD and lacks any viewfinder. While sufficient for casual use, it limits usability in bright environments or creative shooting angles.

User interface insights:

  • The Sony’s articulated screen and EVF provide versatility for portrait, macro, and video applications.
  • The Samsung works well for daylight casual use but may frustrate in bright light or challenging angles.

Autofocus and Shooting Performance - Capturing the Moment

A critical aspect for fast-paced photography such as wildlife or sports is autofocus speed, accuracy, and continuous shooting.

Feature Samsung HZ15W Sony SLT-A55
Autofocus Type Contrast detection Phase detection + Contrast detection (Hybrid)
AF Points Center & Multi-area (no count specified) 15 (3 cross-type)
Continuous AF No Yes
AF Tracking No No
Max Continuous FPS N/A 10 fps

The Samsung’s autofocus system relies solely on contrast detection, which is slow and often hunt-prone, making it unsuitable for action or moving subjects. The Sony A55’s hybrid autofocus with 15 points, including cross-type sensors, delivers quick, reliable focus lock and smooth adjustments during continuous shooting at 10 fps - impressive for the time.

For wildlife or sports photographers who need to freeze action or track moving subjects, the A55 is clearly superior.

Lens Ecosystem - How Far Can You Expand Your Creativity?

Lens selection dramatically influences what kinds of photography you can explore.

  • Samsung HZ15W: Fixed 24-240mm equivalent lens (F3.3-5.8).
  • Sony SLT-A55: Sony/Minolta Alpha mount offering 143 lenses at launch, covering:
    • Wide-angle primes and zooms
    • Telephoto and super telephoto lenses for wildlife/sports
    • Macro lenses for close-up detail
    • Fast primes for low light and portraits

The Sony A55’s interchangeable lens system unlocks enormous creative potential. From professional-grade glass to budget-friendly options, you can match lenses to your exact needs and style. Samsung’s fixed lens limits you to its zoom range and aperture.

If you anticipate diversifying your photography genres, Sony offers a growth path.

Flash and Lighting - Options When Natural Breathes Out

The built-in flash on both cameras has different capabilities:

Feature Samsung HZ15W Sony SLT-A55
Flash Range 4.7 meters 10.0 meters (@ ISO 100)
Flash Modes Basic modes (Auto, Red-eye reduction, Slow sync, Fill-in) Extensive modes (Auto, High speed sync, Rear curtain, Wireless)
External Flash Support None Yes (hot shoe with TTL metering)

The A55’s flash system offers flexibility including wireless TTL flash control, crucial for professional lighting setups. Samsung’s limited internal flash is good for casual close-range illumination.

Video Capabilities - Moving Pictures Matter

Video versatility is an important consideration today.

Feature Samsung HZ15W Sony SLT-A55
Max Video Resolution 1280 x 720 (HD) @ 30fps (Motion JPEG) 1920 x 1080 (Full HD) @ 60fps (AVCHD, MPEG-4, H.264)
Audio Input None Microphone port supported
Stabilization Sensor-shift Sensor-based
Articulated Screen for Vlog No Yes

Sony’s advanced video with Full HD at 60fps plus support for external microphones makes it a solid hybrid photo/video solution. The HZ15W’s HD video is more basic, suited for casual recording.

Weather Resistance and Durability

Neither camera features environmental sealing, waterproofing, or shockproofing. Both demand careful handling in rugged outdoor conditions.

Battery Life and Storage

Battery Type Proprietary (unspecified) Battery Pack NP-FW50
Battery Life Not specified (approx. 200 shots typical for compacts) Approx. 380 shots (CIPA)
Storage Media SD/SDHC/MMC SD/SDHC/SDXC and Memory Stick Pro Duo
Storage Slots 1 1

Sony’s battery offers longer life suitable for professional sessions; Samsung’s compact likely needs more frequent recharging.
