Sony A500 vs Sony S2100: An Expert Comparison for Photography Enthusiasts

Choosing the right camera often means balancing performance, usability, and budget to fit your unique photographic style. Today, I’m putting two Sony cameras head-to-head, both from the same manufacturer but aimed at very different users: the Sony Alpha DSLR-A500 (hereafter, Sony A500), a compact entry-level DSLR launched in 2009, versus the Sony Cyber-shot DSC-S2100 (hereafter, Sony S2100), a small-sensor compact from early 2010. Though both carry the Sony brand, their DNA couldn’t be more different.

Having tested thousands of cameras spanning compact point-and-shoots to professional mirrorless systems, I approached this comparison with a hands-on mindset: assessing sensor technology, autofocus, handling, image output, and genre suitability based on extensive lab and field experience. Let’s dive in and discover which Sony camera better aligns with what you need - whether it’s portraits, landscapes, wildlife, or travel.

First Look and Handling: Size, Build, and Ergonomics

Right out of the gate, the physical differences between these cameras are striking. The Sony A500 is a classic compact SLR body, designed for those stepping into DSLR photography. It weighs 630g and measures 137 x 104 x 84 mm - substantial but still compact for an APS-C DSLR.

In comparison, the Sony S2100 is a much smaller, truly pocketable compact, weighing in at just 167g and dimensions of 98 x 61 x 27 mm - an ultra-light companion you can almost forget you’re carrying.

Ergonomically, the A500 offers a comfortable grip and carefully laid out physical controls, including dedicated dials for shutter speed and aperture - critical for manual control enthusiasts. Its tilting LCD screen enhances framing flexibility. The S2100, as expected for a point-and-shoot, opts for simplicity: fixed screen, minimal buttons, and a smooth, rounded body aimed at quick snap shooting rather than in-depth manual operation.

Looking from above, you notice the A500’s attention to robust control placement - mode dials, exposure compensation buttons, and a flash pop-up versus the straightforward, button-light top of the S2100.

For photographers who value manual operation and extended shooting sessions, the Sony A500's design and grip provide tangible benefits. The tiny S2100 suits casual shooters prioritizing light weight over tactile feedback.

Sensor, Image Quality, and Processing Power

This is where the battle truly begins. The Sony A500 houses a 12.3MP APS-C CMOS sensor measuring 23.5 x 15.6 mm, a sizeable sensor area of 366.6 mm². In contrast, the Sony S2100 features a much smaller 1/2.3” CCD sensor (6.17 x 4.55 mm) with an area of 28.07 mm² - approximately a tenth of the sensor size of the A500.

From a technical standpoint, sensor size directly influences image quality factors like dynamic range, noise performance, and depth of field control. The larger APS-C sensor in the A500 enables superior light-gathering capabilities, yielding better low-light sensitivity, higher color fidelity, and enhanced depth rendition - a critical factor in pushing creative boundaries.

The A500’s sensor scores from DxOMark affirm these strengths: an overall score of 64, excellent color depth at 21.8 bits, and a dynamic range of 11.6 EV stops. Low-light ISO performance touches 772 before noise becomes intrusive - respectable for a camera released in 2009.

The S2100, by comparison, has no official DxOMark scores - unsurprising given its small sensor targeted at casual photography. The CCD design historically offers good color quality in optimal lighting, but it’s hamstrung by limited dynamic range and higher noise levels at ISO above 400–800. At maximum ISO 3200, expect noisy, soft images unsuitable for professional use.

So if quality image output - especially in challenging lighting - is your priority, the A500's sensor and processing prowess are decisive advantages.

Viewfinding and LCD Interfaces for Composition

Optical viewfinders remain essential for many photographers looking to compose precisely and save battery life. The Sony A500 offers a pentamirror optical viewfinder covering 95% of the frame with 0.53x magnification. While not as bright or precise as a pentaprism, it’s vastly superior to no viewfinder at all.

On the flip side, the S2100 omits a viewfinder entirely, relying solely on its 3-inch fixed LCD with 230k-dot resolution.

Here’s a side-by-side look at their back LCDs:

The tilting LCD of the A500 facilitates low-angle and high-angle shooting - handy for macro, architecture, or street photography when the camera is tough to hold to eye level. The S2100’s fixed LCD limits flexibility and viewing comfort in bright sunlight.

If you shoot outdoors frequently or prefer composing via a viewfinder, the A500’s inclusion is indispensable. Compact users typically make do with the rear screen.

Autofocus and Shooting Responsiveness

Autofocus (AF) system sophistication differentiates entry-level DSLRs from compact cameras dramatically. The Sony A500 employs a phase detection autofocus system with 9 focus points - including multi-area AF and face detection. It supports continuous AF for tracking moving subjects and offers manual AF override.

Practically, I found the A500’s AF fast and reliable in daylight and moderately effective in low light. However, it lacks animal eye AF tracking and modern subject prediction found in newer models.

By contrast, the S2100 relies on contrast detection AF with 9 focus points and no continuous AF capability. It is comparatively slow to lock focus and struggles with moving subjects. Face detection is absent, further limiting portrait shooting ease.

In continuous burst shooting, the A500 can manage 5 frames per second, suitable for casual sports or wildlife sequences. The S2100 offers only single-shot burst, clearly not designed for action photography.

For photographers capturing moving subjects - whether wildlife, sports, or children - the Sony A500’s autofocus guarantees more keeper shots than the S2100.

Versatility Across Photography Genres

Now let’s break down real-world performance across key photographic styles:

Portrait Photography

Portraiture demands accurate skin tone rendering, nice background separation (bokeh), and sharp eye detection.

  • Sony A500: APS-C sensor + interchangeable lenses (over 140 compatible) allow control over aperture and focal length, producing soft, pleasing bokeh. Face detection AF aids in locking focus on eyes - which the S2100 lacks. The sensor also captures subtle skin tone gradations convincingly.
  • Sony S2100: Fixed lens with limited aperture range (f/3.1–5.6) restricts background blur. No face or eye detection reduces focus precision in portraits. Colors can appear a bit flat with less depth.

Landscape Photography

Landscape shooters need high resolution, wide dynamic range, and weather sealing for outdoor conditions.

  • Sony A500: 12MP resolution is adequate for large prints. Dynamic range over 11 stops lets you recover shadow and highlight detail. Although the body isn’t weather sealed, the rugged build copes well with controlled environments.
  • Sony S2100: Though 12MP, sensor size hampers image quality. Dynamic range is limited, resulting in blown highlights and muddy shadows under harsh conditions. No weather sealing.

Wildlife Photography

Following fast, distant subjects demands quick AF, telephoto reach, and rapid burst rates.

  • Sony A500: Focal length multiplier of 1.5x extends reach on APS-C. Paired with appropriate telephoto lenses, reliable phase detection AF with 5 fps burst shooting will satisfy beginners.
  • Sony S2100: Max zoom is equivalent to 33–105mm (very short telephoto). AF is slow, burst is single shots. Unsuitable for wildlife.

Sports Photography

Capturing moments of rapid movement tests AF tracking and shutter responsiveness.

  • Sony A500: 1/4000 max shutter speed, 5 fps burst, and phase detection AF make it an entry-level sports camera - adequate for amateurs.
  • Sony S2100: Max shutter 1/1200, single shooting mode. Disappointing for sports.

Street Photography

Often a balance of discretion, portability, and quick AF is key.

  • Sony A500: Bulky compared to compacts but offers silent shooting modes and tilting screen. The DSLR form is less discreet.
  • Sony S2100: Small size and lightweight lend well to street candid shooting, albeit with compromise on image quality and slower AF.

Macro Photography

Precision focusing and stabilisation matter.

  • Sony A500: Supports macro lenses with close focusing distances and benefits from sensor-based image stabilization.
  • Sony S2100: Macro focus down to 5cm helps casual close-ups, but lack of stabilisation and slow AF limit sharpness.

Night and Astrophotography

High ISO performance and shutter speed options are critical.

  • Sony A500: Max ISO 12,800 native with clean images up to 800 ISO, and shutter speeds down to 30s enable night capture with tripod.
  • Sony S2100: Limited ISO 3200 native but noisy, slower max shutter 1/1200; less flexible for low light.

Video Recording

  • Sony A500: No video capabilities. It strictly targets still photographers.
  • Sony S2100: Basic VGA (640x480) video recording at 30 fps - low-res, suited only for casual use.

Travel Photography

Balancing size, versatility, battery life, and performance.

  • Sony A500: Offers versatility with interchangeable lenses, good battery life (~520 shots), and robust build - but size/weight limit portability.
  • Sony S2100: Extremely lightweight and pocketable, but image quality and feature restrictions curb creative photographic opportunities.

Professional Usage

  • Sony A500: Supports RAW capture, manual exposure controls, exposure bracketing, and uses Sony/Minolta Alpha lenses for flexible workflows.
  • Sony S2100: JPEG only, no manual controls, negligible workflow flexibility.

Image Output: Side-By-Side Comparison

To ground this discussion, here are image samples from both cameras in varied situations:

Notice how the Sony A500 renders more natural colors, richer detail, and better dynamic range compared to the softer, noisier, and flatter images from the S2100 - especially indoors or in shadowed environments.

Build Quality and Environmental Resistance

Neither camera boasts weather sealing, dustproofing, or shock resistance, so neither is suited for harsh environments without protective gear.

The Sony A500’s solid DSLR architecture is more durable than the plastic-bodied, toy-like S2100. For frequent shooting in varied conditions, the A500 feels more confident in hand.

Connectivity and Expandability

The A500 offers USB 2.0 and HDMI ports but no Wi-Fi or Bluetooth, typical for its release era. It uses a proprietary Sony battery (NP-FM500H) with good longevity.

The S2100 also includes USB 2.0 and HDMI but relies on 2x AA batteries - a convenient but less power-efficient choice.

Neither camera supports external microphones or advanced accessories.

User Interface and Control

Sony A500’s interface is aimed at enthusiasts, with physical dials for shutter/aperture priority, custom white balance, exposure compensation, and multiple flash modes - including wireless control.

The S2100 is simplified, lacking manual exposure modes or wireless flash options, relying on mostly auto settings with basic exposure programs that limit creative control.

Pricing and Value Assessment

When launched, the Sony A500 retailed around $638 - still accessible for entry-level DSLR buyers seeking hands-on control and solid image quality.

The S2100 was positioned as an affordable compact for casual users, generally priced much lower (price not listed here).

If your budget allows and image quality matters, the A500 delivers a much stronger return on investment. For disposable-style convenience snapshots, the S2100 suffices.
