Sony HX30V vs Sony S2100: A Deep Dive into Two Compact Cameras from a Seasoned Photographer’s Perspective

Over my 15-plus years testing cameras extensively - from professional DSLRs to compact point-and-shoots - I’ve learned that the devil is often in the details. When comparing two cameras debuting in the early 2010s like the Sony Cyber-shot DSC-HX30V and the Cyber-shot DSC-S2100, it’s essential to look beyond specs on a sheet and truly understand how each performs in real-world shooting across a variety of photography disciplines. Today, I’ll walk you through my hands-on experience and detailed analysis of these two Sony compacts, highlighting their strengths, compromises, and ideal use cases.

By the end of this journey, you’ll have a clear sense of which camera will suit your style, budget, and creative ambitions best.

Meet the Contenders: Setting the Stage

Before we unfold the story of image quality, autofocus prowess, handling, and more, it helps to understand the fundamental differences you’re buying into.

The Sony HX30V is a small sensor superzoom introduced in 2012. Its 20x zoom range (25-500mm equivalent) immediately tells you it’s designed to be versatile for everything from wide landscapes to distant wildlife. The HX30V features an 18-megapixel back-illuminated CMOS sensor, optical image stabilization, Full HD video at 60fps, GPS for geotagging, and built-in Wi-Fi connectivity - a clear indication Sony had travel and adventure photography in mind.

In contrast, the Sony S2100, launched two years earlier in 2010, is a small sensor compact camera built for simplicity and general use. Sporting a 3.2x zoom (33-105mm equivalent), a 12-megapixel CCD sensor, and limited HD video capacity (640x480 max), its focus was less on reach and bells and whistles and more on classic point-and-shoot ease.

Visually and physically, the HX30V is the chunkier, more robust model while the S2100 embraces pocket-friendliness.

Here you can see the physical size and ergonomics differences. The HX30V’s larger grip and higher profile give it handling advantages in prolonged shooting sessions, especially with longer focal lengths, whereas the S2100’s slim, lightweight body excels in casual, grab-and-go scenarios.

The Heart of Image Quality: Sensor Technology and Detail

My testing regimen for sensor and image quality involves shooting standardized resolution charts, natural scenes in varying light, and controlled low-light conditions, followed by objective and subjective analyses.

The HX30V’s 18MP back-illuminated CMOS sensor offers improved light-gathering efficiency compared to the S2100’s 12MP CCD sensor of older design. The back-side illumination (BSI) reduces noise at higher ISO settings - a distinct advantage in dim environments.

Both cameras utilize a 1/2.3" sensor size (28.07mm² sensor area), common in compacts of their era. The higher resolution counts of the HX30V render images larger and allow for more cropping flexibility. In my hands-on tests, landscape shots from the HX30V revealed finer texture and better overall clarity while maintaining well-controlled noise up to ISO 3200. The S2100 images tend to show more visible noise and softer detail due to sensor limitations, especially beyond ISO 400.

The HX30V’s color reproduction was also more vibrant and accurate, thanks to the BIONZ processor enhancements.

Practical takeaway: If image quality, especially in low light or when cropping is important, the HX30V has a significant edge. The S2100’s sensor performs decently in bright, outdoor settings but quickly loses dynamic range and sharpening under challenging conditions.

Focusing on Focus: Autofocus Systems in Real-World Use

Autofocus speed and accuracy are vital for all types of photography. I evaluate this by shooting moving subjects, portraits with eye-focus checks, macro compositions, and low-light AF responsiveness.

The HX30V’s 9-point contrast-detection AF with face detection and tracking provides noticeable benefits over the S2100’s simpler 9-point contrast AF without face detection capabilities. While neither model sports phase-detection AF (typical of higher-end cameras), the HX30V’s refined algorithm triggers faster lock-on and better target retention.

This difference becomes apparent in snapshot street scenes or casual wildlife photos where the subject may unpredictably shift. For example, I found that the HX30V successfully maintained focus on loosely framed pedestrians walking past uneven lighting, while the S2100 struggled to regain focus quickly.

However, both cameras lack continuous AF and advanced tracking for high-speed action, limiting their use for sports or fast-moving wildlife photography.

Build Quality and Handling: What You Feel Matters

Ergonomics are often overlooked until disappointment sets in. The hands-on test shows the HX30V’s larger grip, more substantial weight (254g vs. 167g), and waterproof-free but solidly built body provide greater confidence - especially important when using the long zoom.

On the top plate, the HX30V features a dedicated zoom rocker, a mode dial, and exposure compensation controls, giving me quick physical access to shooting parameters. The S2100’s simplified control layout prioritizes minimalism, limiting manual control options.

The HX30V also benefits from optical image stabilization in its lens, alleviating camera shake, especially through telephoto zooms. The S2100 has none, producing more blurred shots handholding at longer focal lengths or slower shutter speeds.

Viewing and Interface: Screen Size and Usability

Both cameras have fixed 3-inch LCDs, but their screen technology differs importantly.

The HX30V’s XtraFine TruBlack TFT LCD sports 922k dots, providing a sharper, richer real-time viewfinder compared to the S2100’s lower resolution 230k-dot screen. The increased screen brightness and contrast make composing and reviewing images easier in sunlight.

Neither camera offers a touch interface or electronic viewfinder, which might matter for certain shooting styles or bright conditions.

Lens Capabilities: Zoom Range and Aperture

With a fixed lens system, focal range and aperture define what shots are achievable without external glass.

The HX30V’s 25-500mm (20x optical zoom) lens is a tour de force of flexibility, covering wide-angle to super-telephoto in one compact body. Its maximum aperture of f/3.2-5.8 is reasonable for the range. In my wildlife hikes, this zoom let me frame distant birds and architectural details without changing gear - a huge convenience.

The S2100’s 33-105mm (3.2x zoom) lens is much more restricted but offers a slightly faster max aperture (f/3.1-5.6) - helpful in low-light portraits or indoor shots.

When shooting macro, the HX30V can focus down to 1cm from the lens, enabling impressive close-ups, whereas the S2100’s macro distance is limited to 5cm, requiring more physical maneuvering for detail shots.

Burst Shooting and Video: Capturing the Moment and Motion

Neither camera targets professional sports videographers, but their continuous shooting and video features matter for memories or casual capture.

The HX30V offers a rapid 10 fps burst mode, excellent for capturing fleeting moments like jump shots or playful kids, whereas the S2100 only shoots 1 fps, limiting options for action.

Videography is more advanced on the HX30V, which records full HD 1080p at 60fps in AVCHD format, delivering smooth, high-resolution videos with decent compression. The S2100 caps out at 640x480 VGA at 30fps in Motion JPEG - a dated and low-quality format.

Neither camera has external microphone inputs, so audio capture remains limited on both.

Portability vs Versatility: Which Travels Better?

The lightweight S2100 (167g) with compact dimensions (98x61x27mm) is undeniably pocket-friendly - ideal for casual walking tours, family trips, or street photography where discretion and minimal bulk matter. It fits easily in a jacket pocket or purse and won’t weigh you down.

The HX30V, while larger (107x62x35mm) and heavier (254g), offers incredible versatility through its zoom reach, GPS geotagging, Wi-Fi for easy sharing, and longer battery life (320 shots vs. unspecified in the S2100). This makes it a robust traveler’s tool ready for diverse conditions - from sprawling vistas to close-up wildlife.

The inclusion of wireless connectivity in the HX30V addresses a huge gap for modern workflows, allowing immediate image transfer to smartphones or laptops in the field.

Battery Life and Storage: Staying Power in the Field

The HX30V utilizes a proprietary NP-BG1 rechargeable Lithium-Ion battery rated at roughly 320 shots per charge - a respectable figure given its advanced features. I found that enabling GPS and Wi-Fi may reduce this, so carrying a spare battery is always advisable for extended trips.

The S2100 relies on two AA batteries, which may be convenient as AAs are widely available, but tend to offer less sustainable power and can increase overall carry weight.

Both cameras feature single card slots supporting SD or Memory Stick Duo formats, though the HX30V supports SDXC for larger storage cards, future-proofing capacity especially useful for HD video recording.

Durability and Weather Sealing: Ready for the Elements?

Neither camera offers environmental seals or ruggedization. Neither is waterproof, dustproof, shockproof, or freezeproof. These are important considerations if you plan to shoot outdoors in challenging conditions without extra protective housing.

Overall Performance Ratings and Genre Suitability

Drawing on my thorough lab and real-world testing of autofocus speed, image quality, burst rates, video capabilities, handling, and more, here’s a summarized performance comparison for each photography genre:

• Portraits: HX30V’s face detection AF, higher resolution, and image stabilization make it better for natural-looking skin tones with good bokeh at moderate zooms. The S2100’s limited zoom and no image stabilization constrain its portrait repertoire.
• Landscapes: HX30V wins with higher resolution, better dynamic range, and more effective sensor technology. The 25mm equivalent start focal length covers wide scenes well.
• Wildlife: 20x zoom plus stabilization make HX30V far superior. S2100’s limited reach is ill-suited for wildlife.
• Sports: Neither excel, but HX30V’s 10fps burst edges out S2100.
• Street: The S2100’s compactness and discretion suit candid street shots; HX30V is bulkier but manageable.

Close-up portraits show HX30V skin tones richer with sharper details; landscapes expose the HX30V’s finer textures and better highlights retention. Wildlife shots at 500mm equivalent from HX30V capture more detail on birds with less blur thanks to stabilization.

The S2100 captures decent images in good light but softness and noise creep in under demanding conditions.

Lens Ecosystem and Compatibility: Limitations of Fixed Lenses

Both cameras use fixed lens mounts with no option for interchangeable glass. While this limits creative lens swapping, it simplifies operation and ensures compactness.

For photographers craving wide aperture primes or specialty lenses (macro, tilt-shift, fisheye), neither will suffice. I recommend these cameras purely for convenience and general-purpose shooting.

Connectivity and Modern Features: Staying Current in a Wired World

The HX30V’s built-in Wi-Fi and GPS are remarkable for early 2010s compacts. In travel or street photography, geotagging helps recall locations and Wi-Fi expedites image offload - two features absent in the S2100, which also lacks any wireless options.

Neither includes Bluetooth or NFC, common in today’s cameras, but for their time, the HX30V is forward-looking.

Price and Value in Today’s Market

At launch, the HX30V listed around $420 and the S2100 was positioned as a budget-friendly option.

Today, both are largely obsolete compared to current smartphone cameras and mid-range mirrorless systems, but for collectors or specific use cases, pricing varies. Used HX30Vs tend to command higher resale values reflecting their broader utility.

Value depends on user priorities:

• Choose HX30V if you need zoom versatility, sharp image quality, and advanced functions.
• Opt for S2100 if size, simplicity, and very casual snapshots are your focus.
