Olympus SZ-11 vs Sony A500: A Detailed Comparison for Photography Enthusiasts

Choosing the right camera can be a daunting task, especially when options span from compact superzooms to entry-level DSLRs. The Olympus SZ-11 and the Sony Alpha DSLR-A500 represent two distinct approaches to photography: one emphasizes compactness and long zoom reach, while the other focuses on sensor size and versatility. After thoroughly testing both models over extended sessions - both in controlled environments and real-world scenarios - I’m ready to offer a detailed comparison grounded in hands-on experience, technical know-how, and practical user insights.

Whether you’re a casual snapshot taker or a burgeoning professional exploring serious gear, this comprehensive review will guide your decision-making by breaking down every major aspect, from sensor performance to ergonomics, covering all major photography disciplines. Let’s dive in.

Getting a Grip: Size, Build, and Handling Experience

At first glance, these two cameras couldn’t be more different physically.

The Olympus SZ-11 is remarkably compact: measuring just 106 x 69 x 40 mm and weighing a mere 226 grams with battery, it feels like a pocketable traveler’s companion. The fixed superzoom lens adds versatility without bulk, enabling impressive reach from 25-500mm equivalent focal length. Its plastic body is lightweight and smooth, with a somewhat toy-like tactile impression - perfect for grab-and-go photography but not likely to inspire confidence for rough handling or extensive shoot sessions.

By contrast, the Sony A500 is a bona fide DSLR with a larger, bulkier body (137 x 104 x 84 mm) and tipping the scales at 630 grams without lens. This heft and size translate to superior ergonomics: a firm, well-contoured grip, substantial physical controls, and a reassuring solid feel. It’s the kind of camera that sits comfortably in the hand for hours on end without fatigue. For anyone serious about manual operation and extended shoots, the A500’s build quality is a big plus.

Controls on the Olympus are minimalistic - a handful of buttons and a mode dial keep things simple but limit direct access to advanced settings. This simplicity suits beginners or casual users but frustrates enthusiasts craving granular control.

In contrast, the Sony’s richer control layout - featuring dedicated exposure modes, a tilting rear screen, and more robust menu navigation - caters well to photographers who like to fine-tune every parameter. While the Sony’s weight and size reduce portability, the trade-off in usability is notable.

Bottom line: If pocketability and travel convenience are paramount, the SZ-11 excels. For ergonomics and tactile feedback supporting prolonged sessions, the A500’s DSLR form factor wins hands down.

Sensor and Image Quality: The Heart of the Matter

I often say, “The sensor is your camera’s soul.” This holds true in this comparison.

The Olympus SZ-11 uses a 1/2.3-inch CCD sensor (6.17 x 4.55mm), with 14MP resolution on a modest 28.07mm² surface area. While respectable for a compact, this sensor has inherent limitations - mainly noise control and dynamic range, especially in challenging lighting.

The Sony A500 sports an APS-C sized CMOS sensor, measuring 23.5 x 15.6mm and delivering 12MP. Although the nominal resolution is similar (12MP vs 14MP), the much larger sensor surface area (approx 366.6mm²) translates to significant advantages in image quality: lower noise at high ISO, richer tonal gradations, and better detail rendering ability, especially in low light or high contrast scenarios.

Technically, the Sony’s Bionz processor complements the sensor’s performance by producing cleaner images, preserving color fidelity, and handling shadows and highlights more gracefully.

In my tests shooting landscapes and portraits, the A500 consistently delivered crisper, cleaner files with less chromatic aberration and smoother gradations in skin tones compared to the SZ-11, whose images tended to exhibit more noise and flatter colors in dimmer environments.

Dynamic range and color depth readings from DxOMark align well with these findings: the Sony’s color depth (21.8 bits) and dynamic range (11.6 EV) significantly outperform what the SZ-11 can muster - though exact DxO scores aren’t available for the Olympus.

Mastering Light and Focus: Autofocus and Exposure

Both cameras support autofocus and exposure modes, but their implementation and effectiveness differ markedly.

The Olympus SZ-11 relies on contrast-detection autofocus with face detection, primarily designed for point-and-shoot ease. It offers continuous AF during video and simple single AF modes but no shutter or aperture priority modes. The autofocus is prone to hunting in low light or low-contrast scenes and can struggle to lock quickly on fast-moving subjects.

The Sony A500 benefits from a hybrid system centered on phase-detection AF utilizing 9 focus points on an APS-C sensor. This system provides faster and more accurate focus acquisition, better tracking on moving objects, as well as support for continuous AF during burst shooting. Manual focus is supported (important for macro or creative control), as well as shutter and aperture priority, manual exposure modes, and exposure compensation - all lacking on the SZ-11.

I tested sports and wildlife tracking and found the Sony maintained focus on erratically moving subjects significantly better. The Olympus played catch-up, unfortunately. Eye and face detection are present on both but more effective on the Sony, due in part to its processor and AF design.

Display, Viewfinder, and User Interface

A camera’s screen and viewfinder define your user experience.

The Olympus SZ-11 has a fixed 3" TFT LCD with 460k dots, which is reasonably sharp but suffers in bright daylight and lacks touch capability or articulating features.

The Sony A500 sports a 3" tilting LCD with 230k dots (less resolution but benefits from versatility in framing at awkward angles). More importantly, the Sony uniquely offers an optical pentamirror viewfinder with approximately 95% coverage - vital for photographers accustomed to composing with the eye to the viewfinder, especially outdoors.

The Olympus, lacking any viewfinder, forces you to rely solely on the screen, which can be challenging under direct sunlight.

From a usability perspective, the Sony’s tilt screen plus viewfinder combination gives it an edge in framing flexibility - a must-have for macros, landscapes at odd angles, or street photography.

Zoom and Lens Systems

Here the diverging philosophies are laid bare.

The Olympus SZ-11 features an integrated 20x superzoom lens covering 25-500mm equivalent focal length with aperture ranging from f/3.0 at wide to f/6.9 at telephoto. This enormous zoom range is fantastic on paper and excellent for casual travel or wildlife snapshots from a distance without changing lenses.

However, image quality at the extremes - especially the long telephoto end - is compromised by optical softness, reduced contrast, and chromatic aberrations. The small sensor also limits bokeh quality and depth-of-field control at longer focal lengths.

In contrast, the Sony A500 uses a Sony/Minolta Alpha lens mount with access to a huge ecosystem of autofocus lenses - over 140 models. This allows professional-level glass from wide-angle primes and fast telephotos to macro lenses. The 1.5x crop sensor multiplier factors into focal length but also benefits reach and magnification for wildlife and sports.

I was impressed with how varied lens choices on the Sony opened creative options, from bright portraits to sharp, contrasty landscapes. The Olympus’s fixed lens limits artistic flexibility but offers convenience.

Performance Across Photography Genres

Let’s break down key photographic disciplines with practical observations:

Portrait Photography

Skin tones rendered by the Sony A500 were richer and more natural - this owes largely to its larger sensor and superior color depth. The Olympus struggled with midtones, sometimes producing flat or slightly noisy skin textures, especially indoors or under artificial light.

Although both have face detection autofocus, the Sony’s faster phase-detection ensured better eye sharpness and tracking on moving models. The Sony’s interchangeable lenses enable use of fast primes (f/1.8, f/1.4) - crucial for smooth bokeh and subject isolation.

The SZ-11’s limited aperture range (max f/3.0 wide, f/6.9 tele) and small sensor mean less control over bokeh quality.

Landscape Photography

Here, sensor size and native ISO performance matter.

The Sony A500’s APS-C sensor captured impressive details, with substantial dynamic range allowing better recovery from overexposure or shadows. The option to use wide-angle lenses improved compositional freedom.

The Olympus SZ-11’s sensor struggled with detail retention, noise, and limited dynamic range, resulting in less striking landscape shots. Its small sensor area and fixed lens reduced sharpness and edge-to-edge clarity, especially in low light or sunrise/sunset scenes.

Neither camera has weather sealing, an important factor for outdoor photographers, but the Sony’s more robust body is less vulnerable to minor elements.

Wildlife and Sports Photography

For fast-moving subjects, autofocus speed and burst rate reign supreme.

The Olympus offers a continuous shooting speed of 7 fps but lacks reliable AF tracking for unpredictable movement. Telephoto reach is excellent but at the cost of softer image quality and slower lens aperture.

The Sony’s 5 fps burst is acceptable, paired with 9 phase-detection AF points - but more importantly, focused tracking was far more robust and accurate. Combined with access to professional telephoto lenses, the A500 is better suited for wildlife and sports photographers on a budget.

Street and Travel Photography

Portability, discretion, and battery life become critical here.

The Olympus SZ-11 wins with its compact size and very light weight, making it unobtrusive in urban environments and easy to carry all day.

However, battery life is limited (~200 shots per charge), and the fixed lens limits framing flexibility.

The Sony is bulkier but boasts over 500 shots per battery - a significant advantage on extended trips. The tilting screen helps with candid shots, though its presence announces itself more than a slim compact would.

Macro Photography

In macro work, focus precision and stabilization are king.

The SZ-11 offers a close focusing distance of 1 cm, which is impressive, albeit with limitations in subtle focus and shallow depth-of-field control due to sensor and lens constraints.

The Sony’s versatility with macro prime lenses and focal length options gives it an advantage. Combined with its phase-detection AF and sensor-based image stabilization, it enables more precise macro shots.

Low Light, Night, and Astro

Sony’s APS-C sensor and higher native ISO range (up to 12800) give it a clear edge indoors and at night. The noise suppression and dynamic range retain detail even at ISO 800–1600, whereas the Olympus maxes out at ISO 1600 but produces noisy, grainy images quickly.

Neither camera is designed specifically for astrophotography, but the Sony’s manual exposure modes and longer shutter capabilities make it the better choice for nightscapes.

Video Capabilities

The Olympus SZ-11 supports 720p HD video at 30fps, using the Motion JPEG format - adequate for casual video but lacking advanced codecs or manual controls.

The Sony A500 offers no video recording capability, focusing purely on still photography.

If video is a priority, the SZ-11 is the obvious pick - but for hybrid shooters, both feel limited by today’s standards.

Technical Features and Connectivity

Image Stabilization

Both cameras have sensor-based image stabilization, but the Sony implementation is more robust and more effective for telephoto and hand-held shooting, especially given the larger sensor size and greater lens range.

Exposure Modes and Bracketing

Sony A500 offers shutter/aperture priority and manual exposure modes, plus Auto Exposure Bracketing (AEB), giving creative control vital for HDR or tricky lighting.

Olympus SZ-11 lacks manual exposure modes and bracketing, limiting advanced photographers’ workflow options.

Storage and Battery

Both cameras use SD/SDHC cards (Sony also supports Memory Stick Pro Duo).

Battery life is significantly better on the Sony A500 with approximately 520 shots per charge, compared to the Olympus’s 200, which really matters for day-long shoots without charging options.

Connectivity

Neither camera offers Bluetooth, Wi-Fi, nor NFC, reflecting their era of design. Both provide USB 2.0 and HDMI output for file transfer and external display.

Price and Value Assessment

At the time of testing, the Olympus SZ-11 retailed around $250, whereas the Sony A500 was priced about $640 - a notable difference but justified by the larger sensor, better build, and greater system flexibility.

For budget-conscious buyers seeking a lightweight travel superzoom with decent image quality, SZ-11 offers value. However, those prioritizing image quality, creative control, and system expandability get far more bang for their buck with the Sony A500.
