Sony A850 vs Sony WX10: A Deep Dive into Two Worlds of Photography

Choosing a camera is a highly personal decision - it hinges on your photographic style, technical requirements, and budget. Today, I’m bringing forth an intensive comparison between two starkly different cameras from Sony’s lineup, each representing vastly different eras and philosophies of photography: the Sony Alpha DSLR-A850 (commonly known as the Sony A850), a full-frame DSLR aimed at advanced enthusiasts and professionals, and the Sony Cyber-shot DSC-WX10, a compact point-and-shoot camera designed for casual shooters and travelers who want convenience in a pocket-sized form.

Having spent well over a thousand hours testing and shooting with cameras both in studio and the field, I bring you hands-on insights, technical analyses, and real-world use cases to help you make a confident choice between these devices. Let’s start by setting the scene with a look at their physical profiles and ergonomics.

Size, Handling, and Ergonomics: When Weight & Bulk Matter

Physically, the Sony A850 and WX10 could hardly be more different. The A850 weighs a hefty 895 grams and measures 156x117x82 mm - a mid-sized DSLR with an unmistakable robust presence. Its heft and construction hint at a camera built to be held for longer sessions - the kind of tool you rely on for meticulous setups and deliberate shooting.

The WX10, on the other hand, weighs a mere 161 grams and shrinks down to 95x54x23 mm. It fits effortlessly in any pocket or purse, urging spontaneous snaps and quick reactions. This compactness appeals to travelers and casual shooters who prioritize portability above all.

How does this translate to usability? The A850’s thoughtfully contoured body and tactile buttons provide excellent grip and intuitive access - vital when you’re working in rapidly changing environments or manipulating settings on the fly. Conversely, the WX10’s petite frame limits physical control options, relying mostly on menu navigation through a small screen and a limited number of buttons. This inevitably slows down operation and may frustrate advanced users who crave manual dexterity.

In brief, if you’re planning to shoot with pro-grade lenses, lugging the A850 is an expected trade-off for precision and control. For people who want to capture moments without bulk, the WX10 is a champion of convenience.

Control Layout and Display: Usability in Action

Taking a closer look at their control architecture, the A850’s top plate is adorned with essential dials and switches for mode selection, exposure adjustments, and ISO control - a layout that aligns well with traditional DSLR conventions. These allow rapid setting changes without diving into menus - a life-saver when time is short.

The WX10, reflecting its compact segment, has a minimalist top design - limited external controls and dependence on the rear 2.8-inch Clear Photo LCD Plus screen (460k dots) for navigation and framing. While readable, the screen’s resolution and size make fine-tuning fastidious settings or previewing details less than ideal for critical workflow.

Interestingly, the A850 uses a 3-inch TFT Xtra Fine LCD with higher 922k-dot resolution. This translates to a noticeably sharper and clearer display, making image review and focus confirmation more precise. However, since the A850 lacks live view and touchscreen features, you’ll be working mainly through the optical pentaprism viewfinder (covering 98% frame and magnification of 0.74x) for composition, which I find preferable for stability and clarity during fast-paced sessions.

The WX10’s absence of any form of viewfinder means you’re tethered to the LCD for composing shots, which can be challenging under bright outdoor conditions and for tracking moving subjects.

Sensor and Image Quality: Full-Frame Power vs. Compact Convenience

The most striking technical contrast lies in sensor technology and size. The Sony A850 boasts a large full-frame CMOS sensor, measuring 35.9 x 24 mm, offering a massive sensor area of approximately 862 mm² and a 24.6-megapixel effective resolution (6,048 x 4,032 pixels). This sensor size is the gold standard for image quality, delivering exemplary dynamic range, color depth, and low-light performance.

In contrast, the WX10 employs a smaller 1/2.3-inch BSI-CMOS sensor (around 6.17 x 4.55 mm with 16 megapixels). While this sensor is great for pocket cameras and is designed for efficiency, it cannot match the full-frame sensor's ability to resolve fine details, produce shallow depth of field, or control noise at high ISO settings.

Delving deeper - the A850 scored very well in DxOMark metrics with:

• Overall score: 79
• Color depth: 23.8 bits
• Dynamic range: 12.2 EV stops
• Low-light ISO: 1415 (ISO sensitivity at which noise becomes visible but not severe)

Compared to no official DxO measurements for the WX10, we can extrapolate from sensor size that its color depth and dynamic range are modest, with limited high-ISO performance.

The large sensor surface of the A850 also facilitates superior fine-art reproduction, making it particularly suitable for portraits, landscapes, and professional print work.

Autofocus Systems: Precision and Speed Realities

Advanced autofocus (AF) is another realm where the two diverge significantly. The A850 features a 9-point phase-detection AF system with support for continuous AF modes. While not cutting-edge by today’s mirrorless standards, this AF system holds up well for a 2010-era DSLR. It also includes manual and aperture priority modes, offering photographers granular control to craft their image precisely.

The WX10 uses contrast-detection AF with nine selectable focus points and lacks advanced tracking or eye-detection features. Its AF is optimized for simplicity and general use rather than speed or endurance.

This means for action genres such as sports and wildlife photography, the A850’s autofocus system is far superior - providing adequate focus tracking at 3 frames per second continuous shooting. The WX10’s 10 fps burst mode is impressive numerically but limited by its less complex AF system and smaller buffer.

Photography Genres: Real-World Performance and Suitability

Let’s now examine how each camera fares across various photographic disciplines, drawing from hands-on testing and measurement.

Portrait Photography: Skin Tones and Bokeh Mastery

Portrait photography demands precise skin tone rendering, accurate autofocus for eyes, and pleasing background separation. The A850 shines here, with its full-frame sensor offering natural skin tones thanks to richer color depth and smooth tonal gradation. The availability of high-quality Sony Alpha/Minolta lenses with fast apertures also delivers beautiful bokeh, isolating subjects effectively.

However, the WX10’s small sensor and compact zoom lens can’t reproduce the same creamy background blur. While it handles skin tones reasonably well under good lighting, detail smoothness and tonal subtlety is limited, especially when using digital zoom or shots at maximum aperture of f/2.4–5.9.

Neither model provides eye detection autofocus, which has become common in newer cameras - so manual focus checking is recommended for portraits with either.

Landscape Photography: Dynamic Range and Weather Sealing

When I took the A850 into diverse outdoor conditions for landscapes, I appreciated its 12.2 EV dynamic range, which captured emphatic detail in shadowed and bright areas alike. The 25-megapixel resolution also results in images suitable for large prints and cropping without loss.

Importantly, the A850’s environmental sealing adds a layer of protection against dust and moisture, making it far more reliable in adverse weather compared to the WX10, which lacks any environmental ruggedness.

The WX10’s sensor and lens can produce respectable results in good light but lose detail and latitude in high-contrast scenes.

Wildlife and Sports Photography: Autofocus and Burst

For wildlife and sports, autofocus speed and frame rate are critical. The Sony A850’s 3 fps shooting, coupled with phase-detection AF and a broad lens ecosystem (telephoto lenses with long reach), makes it a workable, if not top-tier, option. The extensive availability of tele lenses in the Sony Alpha mount area lets you customize your kit.

The WX10’s 10 fps burst appears faster on paper but is handicapped by limited AF and lens reach (24–168 mm equivalent). Its built-in zoom lens also cannot accomplish the reach or image quality demanded by serious wildlife shooters.

Street and Travel Photography: Portability vs Versatility

The WX10 excels for street and travel photography because of its diminutive size, light weight, and quick startup. It’s non-intimidating and suited to discreet shooting in crowds.

Conversely, the A850 demands a dedicated bag and more intentional use but offers unmatched image quality and access to a huge lens selection for versatile shooting styles.

Macro and Close-Up Photography: Focus Precision

Neither camera includes specialized macro focusing features or focus stacking. However, the WX10's close focusing range down to 5 cm affords some decent close-up capability for casual nature shots or product photography, while the A850 depends on lens choice to define macro abilities - and many Sony/Minolta lens offerings include excellent macro options.

Night and Astro Photography: Low-Light Strength

The A850’s high ISO capability up to 3200 natively (expandable to 6400) and its strong noise control make it suitable for low-light indoor scenes and even astrophotography with the right tripod and lens.

The WX10, while having a native range up to ISO 3200, exhibits significant noise at high ISOs due to sensor limitations, constraining its usefulness in dark environments.

Video Capabilities: Two Different Eras

The WX10 offers HD video recording (up to 1920x1080 at 60 fps) in MPEG-4 and AVCHD formats with optical image stabilization - a boon for casual videographers wanting smooth clips in a compact device.

The A850, released in 2010, lacks any video recording capabilities altogether - reflecting the transitional DSLR era where stills were the primary focus.

Neither camera has microphones or headphone jacks for advanced audio control. For videographers, this clearly positions the WX10 as the multimedia-friendly choice, albeit with caveats on manual video control.

Build Quality and Weather Resistance: Longevity in the Field

The A850 scores highly on build quality with its environmental sealing helping protect against dust ingress - beneficial for outdoor shooting in varied climates.

The WX10 is more delicate, designed for protected casual use without weather sealing.

Battery Life and Storage: Practical Considerations

The A850 utilizes the NP-FM500H battery pack, rated by Sony for approximately 880 shots per charge under standard conditions - quite robust for fieldwork.

The WX10 uses the smaller NP-BG1 battery, with less official data available but generally offering moderate shooting capacity suited for day trips.

In storage, the A850 employs dual Compact Flash or Memory Stick slots - catering to professional workflows and extended shooting, whereas the WX10 works with a single SD/Memory Stick Duo slot, typical for compacts.

Connectivity and Wireless Features: Classic vs Early Modern

Interestingly, the WX10 supports “Eye-Fi Connected” cards for wireless image transfer - a neat feature that predates more integrated Wi-Fi solutions.

The A850 does not have wireless connectivity, relying on USB 2.0 and HDMI ports for tethered operations. This is typical for DSLRs predating wireless standards.

Image Samples and Practical Results
