Sony RX100 V vs Sony S2100: A Thorough Comparison from an Expert’s Perspective

Selecting a camera that perfectly fits your needs can feel overwhelming, especially when comparing models from the same brand but vastly different generations and form factors. Today, we pit two Sony compact cameras head-to-head: the advanced Sony Cyber-shot DSC-RX100 V, launched in late 2016, and the entry-level Sony Cyber-shot DSC-S2100 from 2010. Both fall under the “compact” umbrella, but are engineered for very different audiences and use cases. Drawing from years of hands-on testing veteran camera gear, I’ll unpack the critical differences and practical implications for photographers - beginners, enthusiasts, and professionals alike.

Let’s dive in.

Size and Handling: Portability Meets Ergonomics

If you’ve ever had to stuff a camera into your pocket or juggle it all day during a shoot, size and handling quickly become make-or-break factors.

At first glance, the RX100 V is a more substantial pocketable camera, measuring 102x58x41 mm and weighing 299 grams. The S2100 feels smaller and lighter at 98x61x27 mm and just 167 grams. The RX100 V’s larger footprint accommodates a bigger sensor, advanced physical controls, and a tilting screen, while the S2100 sticks to an ultra-compact design with fewer bells and whistles.

Why Size Matters:

• RX100 V: Though larger, the RX100 V feels solid and ergonomic in hand. The grip and thoughtfully placed buttons reduce fatigue during long sessions, making it comfortable for advanced photography and video work.
• S2100: Lighter and slimmer, this camera suits casual snapshots and travelers who prioritize minimal gear weight over advanced features.

Bottom line: If you want a truly pocket-friendly camera for everyday carry, the S2100 checks that box more comfortably. But if you prioritize control and performance, the RX100 V’s size is justified.

Design and Control Layout: Interface and Usability

Experienced photographers know how intuitive controls and layout can accelerate shooting and creative exploration.

The RX100 V comes equipped with multiple dials, customizable buttons, and an electronic viewfinder, giving you quick access to exposure settings and manual controls favored by pros.

By contrast, the S2100 features a very simplified button layout with no manual exposure modes or viewfinder, limiting its appeal for advanced shooting techniques. The absence of aperture or shutter priority means you’re firmly in “point and shoot” territory.

First-hand usage notes:

• The RX100 V’s physical controls offered me fast, tactile adjustments, indispensable on dynamic shoots.
• The S2100’s reliance on menus and auto modes can frustrate those wanting creative input.

Sensor: The Heart of Image Quality

No amount of processing can fully compensate for sensor size and quality. This is where considerable gaps emerge between these two cameras.

• RX100 V boasts a 1-inch BSI-CMOS sensor (13.2x8.8 mm) with 20MP resolution.
• S2100 uses a small 1/2.3" CCD sensor (6.17x4.55 mm) at 12MP.

The RX100 V’s sensor area is more than four times larger, resulting in markedly better image quality, dynamic range, and low-light performance.

Real-world impact:

• The RX100 V produces images with richer colors, tonal gradations, and finer detail, especially noticeable in challenging lighting.
• The S2100 images tend toward softer details, more noise at higher ISO, and limited dynamic range, typical of small-sensor compacts from the era.

The RX100 V also supports RAW capture, enabling nuanced post-processing - the S2100 does not.

Image Quality in Different Photography Genres

Through my testing, I evaluated these cameras across various genres to give you actionable insights.

Portraits: Skin Tones and Eye Detail

The RX100 V’s large sensor and fast f/1.8 lens at 24mm translate into beautifully rendered skin tones and subtle bokeh separation. Its face detection autofocus works reliably, locking onto eyes for sharp portraits even at wide apertures.

The S2100, with slower lenses (f/3.1–5.6) and limited AF technology, struggles to isolate subjects against backgrounds. Skin rendering appears flatter and less nuanced.

Landscape Photography: Resolution and Dynamic Range

Landscape demands resolving fine details and managing shadows/highlights. The RX100 V’s 20MP sensor and 12.4 EV dynamic range excel here. Weather sealing is absent but not unexpected in this compact class.

S2100’s 12MP CCD sensor limits detail, and the narrower dynamic range constrains highlight recovery. For casual snapshots of scenery, it's fine but falls short of enthusiast landscape standards.

Wildlife and Sports: Autofocus and Burst Performance

For action photography, the RX100 V’s 315 AF points, hybrid phase/contrast detection, and 24 fps burst shutter open up exciting possibilities. I tested wildlife sequences - fast-moving birds and runners - with strong tracking accuracy.

The S2100 offers just 9 AF points and single-frame shooting; continuous autofocus and high frame rates are absent. The slow burst speed hampers any serious action photography.

Street Photography: Discretion and Low Light Handling

Here size and silent operation count. While the S2100 is more compact and quieter, the RX100 V’s silent electronic shutter (max 1/32000s) provides stealthy shooting options - ideal for candid moments. The superior ISO performance on the RX100 V allows cleaner images in dim scenes.

Macro Photography: Close-up Precision

Both cameras focus down to 5 cm, but the RX100 V’s sharper lens and optical image stabilization aid in capturing detailed macro shots handheld. The S2100’s fixed lens and no stabilization limit sharpness and composition options.

Night and Astrophotography: High ISO and Exposure Control

The RX100 V shines with native ISO up to 12800, extended to 25600, whereas the S2100 maxes at ISO 3200. The RX100 V’s manual exposure modes and long shutter speeds enable creative night photography, a capability lacking in the S2100.

Video Capabilities: Specifications and Practical Use

Video is a growing criterion for many creatives and hybrid shooters:

• RX100 V records up to 4K UHD (3840x2160) at 30p with 100 Mbps bitrate using the XAVC S codec. Optical stabilization and reliable AF tracking make it a formidable compact video tool. Unfortunately, no mic or headphone jacks limit audio options.

• S2100 records VGA (640x480) at 30 fps in Motion JPEG, offering only casual video capture. No stabilization or advanced features.

In-hand, the RX100 V enables versatile shooting styles - from smooth handheld travel clips to detailed 4K vlog content - whereas the S2100 is simply an afterthought.

Build Quality and Weather Sealing

Both cameras lack environmental sealing, consistent with their compact designs.

However, the RX100 V retains a premium feel with robust metal chassis and better durability, whereas the S2100 feels budget-oriented with plastic construction.

If you’re shooting outdoors in unpredictable conditions regularly, neither offers full protection, so plan accordingly.

Ergonomics and User Interface: Screen and Viewfinder

The RX100 V’s 3-inch 1229k-dot tilting LCD and 2.35 million-dot electronic viewfinder (EVF) provide superb framing flexibility even under bright sunlight.

The S2100 sports a 3-inch fixed LCD but at just 230k resolution and no viewfinder, making it far less versatile when composing in challenging light or tight spaces.

Autofocus System: Technology and Speed

The RX100 V features Sony’s hybrid autofocus, combining 315 phase-detection points with contrast detection. This hybrid system delivers rapid, accurate focusing with reliable subject tracking and face detection.

The S2100 only uses contrast-detection AF with 9 points, offering slower, less precise focusing, particularly struggling in low light or fast action.

Hands-on tests confirmed that RX100 V locks focus swiftly and continuously tracks subjects in demanding scenarios like sports or wildlife, while the S2100 often hunts and lags behind fast-moving targets.

Lens and Zoom Range: Flexibility and Speed

• RX100 V: 24-70mm equivalent with a bright variable aperture (f/1.8-2.8). This fast zoom allows shooting in dim light and artistic shallow depth of field.
• S2100: 33-105mm equivalent at f/3.1-5.6, a noticeably slower lens limiting low-light ability and background blur.

If you value creative control over your depth of field and need a versatile zoom, the RX100 V wins hands down.

Battery Life and Storage

RX100 V uses the proprietary NP-BX1 battery for about 220 shots per charge - on the low side compared to DSLRs but typical for compact high-performance cameras. Recharge is fast and charging through USB is supported.

The S2100 uses standard AA batteries, convenient but less efficient. Official battery life data is sparse, but expect fewer shots per set than lithium-ion cells.

Both use a single card slot compatible with SD cards. The RX100 V additionally supports Sony’s Memory Stick Pro Duo.

Connectivity and Extras

• RX100 V: Built-in Wi-Fi and NFC enable easy image transfer and remote camera control on smartphones - features all enthusiasts and professionals appreciate.

• S2100: No wireless features, limiting integration with mobile workflows.
