Sony A850 vs Sony WX1

Exploring Two Extremes: Sony A850 DSLR vs. Sony WX1 Compact – A Hands-On Comparison for Photographers

Choosing the right camera often means striking a balance between image quality, usability, and portability - an ongoing challenge I’ve faced countless times during my 15+ years of testing hundreds of camera models. Today, I’m putting head-to-head two Sony models that inhabit totally different worlds yet share the same DNA: the Sony Alpha DSLR-A850, a full-frame advanced DSLR from 2010, and the Sony Cyber-shot DSC-WX1, a pocket-sized ultracompact from 2009. Both targeted photography enthusiasts but addressed completely different use cases and workflows.

In this comprehensive exploration, I’ll draw from my own extensive laboratory testing combined with real-world shooting experiences across every major photography genre. Whether you seek maximum image fidelity for professional projects or a versatile travel companion for casual snaps, understanding the strengths and trade-offs of these two cameras can help you make an informed, lasting choice.

First Impressions: Size, Handling & Build Quality

Right off the bat, the physical disparity between these two cameras is striking. The Sony A850 is a robust mid-size DSLR tipping the scales at about 895 grams and sporting a 156x117x82mm body. The WX1, in contrast, is ultra-slim and pocketable at 149 grams and just 91x52x20mm.

Handling the A850 feels substantial and reassuring, thanks to a deep handgrip, mechanically responsive dials, and a shutter button that’s precise without being overly stiff. This is a camera built for extended shoots; I’ve used it for hours on landscape excursions and portrait sessions without fatigue. The WX1’s compactness is its appeal, sliding easily into a jacket pocket. Its plastic body feels reasonably sturdy but clearly prioritizes portability over durability or advanced weather sealing.

The A850’s well-laid-out top panel includes dedicated dials for exposure compensation, shooting modes, and a top LCD, allowing quick adjustments without diving into menus - a true boon when lighting conditions rapidly change. The WX1 offers a minimal control layout intended for casual users, relying mostly on menus with a small, somewhat dim LCD screen.

Sensor Specifications & Image Quality: The Sensor Size Divide

At the heart of any camera is the sensor. The A850’s full-frame 35.9x24mm CMOS sensor delivers 24.6 megapixels at a native ISO range of 200-3200 (expandable to 6400). By comparison, the WX1’s 1/2.4” (6.1x4.6mm) BSI-CMOS sensor clocks in at a considerably lower 10 megapixels with an ISO range of 160-3200.

The sheer difference in sensor size - roughly 30 times larger in area for the A850 - translates to fundamentally better image quality, especially in detail rendering and low-light performance. I conducted standardized lab tests measuring color depth, dynamic range, and noise performance. The A850 scored a DXOmark overall of 79, delivering stunning 23.8 bits of color depth and a 12.2 EV dynamic range, enabling me to capture nuanced shadow and highlight detail in complex lighting scenarios like sunset landscapes and concert portraits.

The WX1, designed for snapshots and pocket convenience, cannot compete in this realm. Its small sensor struggles with noise at higher ISOs, limiting usable low-light performance. However, its BSI-CMOS design boosts sensitivity over older compact sensors, producing respectable daylight images. I found its color reproduction decent, though less nuanced than the A850’s, and dynamic range notably constrained.

Display and Interface: Viewing Your World

The A850 features a 3-inch TFT Xtra Fine color LCD with 922K dots, fixed in place (no articulating). In practical use, this translates to razor-sharp image review and menu navigation, though situationally awkward angles require peering through the optical pentaprism viewfinder that covers 98% of the frame. If you’re used to DSLR shooting habits, this is entirely comfortable.

The WX1’s smaller 2.7-inch display carries only 230K dots - noticeably less sharp - and it lacks any viewfinder entirely, relying purely on this screen for composition. Outdoors, screen glare and resolution can hamper precise framing, but the camera’s size compensates by being speedy and unobtrusive for street and travel photography.

Given my frequent use under sunny skies and dim interiors, I much prefer the clarity and tactile feedback of the A850’s viewfinder plus screen combo. The WX1 is optimized for convenience over precise control.

Autofocus Systems: Speed and Accuracy

Here, the divide corresponds to their respective intended users. The A850 incorporates Sony’s 9-point phase-detection autofocus system with multi-area and center-weighting options. Though not cutting-edge by today’s fast AF standards, it showed reliable single-shot autofocus precision and decent continuous AF for moderate action.

The WX1 uses a contrast-detection autofocus system with 9 AF points and lacks face or eye detection. During my tests, autofocus speed was adequate indoors but slow and sometimes hunting in low contrast or dim light - a limitation common to compacts of its era.

For demanding wildlife or sports shooting, the A850’s phase-detection system and buffering capabilities gave me more confidence in tracking fast subjects, but its modest 3 fps continuous shooting rate is restrictive. The WX1’s burst mode reached 10 fps but reduced resolution and had more limited AF flexibility.

Lens Ecosystem: Flexibility vs. Fixed Convenience

An undeniable advantage the A850 holds is compatibility with Sony’s extensive Alpha mount lens lineup. With 143 native lenses including world-class primes and professional zooms, you can tailor your setup to any genre - from ultra-wide landscapes and portrait bokeh masters (85mm f/1.4) to super-telephoto wildlife lenses.

In contrast, the WX1 sports a fixed 24-120mm (equiv.) zoom lens with a variable aperture of f/2.4-5.9. It offers usable versatility for casual shooting from wide environmental shots to short telephoto portraits but cannot be upgraded or interchanged - a sacrifice for its pocketability.

Performance Across Photography Genres

Understanding how each camera performs in real photographic settings is critical. I brought both cameras on multiple assignments - portrait sessions, landscapes, wildlife hikes, sports events, street photo walks, macro explorations, night shoots, travel trips, and even some video tests.

Portrait Photography

The A850’s large full-frame sensor truly shines for portraits. Skin tones render with rich tonality and smooth gradations, making post-processing less of a chore. The combination of wide-aperture lenses and the sensor size delivers naturally creamy bokeh, isolating subjects beautifully. Though it lacks modern eye autofocus, the manual-select AF points and center-weighted metering enabled me to nail shots with the eye in sharp focus.

The WX1, constrained by small sensor and fixed lens aperture, struggles to produce shallow depth of field. Portraits come out reasonably sharp but tend to feel flatter and less three-dimensional. Yet for casual users snapping friends or family, it captures acceptable shots when lighting is good.

Landscape Photography

HDR and dynamic range capabilities dominate landscape work. The A850’s 12.2 EV DR lets me retain detail in shadowed trees and bright skies from the same frame, a lifesaver when chasing golden hour or stormy scenes. Its weather resistance adds peace of mind on outdoor shoots with changing conditions.

The WX1’s lesser dynamic range results in blown highlights or blocked shadows, though high-resolution stills offer decent color in bright daylight. The compact size makes it great for hikes, but I found its weather sealing absent and distortion at the wide-end lens more noticeable.

Wildlife Photography

The A850 accommodates fast prime and telephoto lenses essential in wildlife work. Subject tracking is limited by autofocus sophistication and frame rate, but patience and technique can yield sharp shots, especially when paired with prime optics. Its built-in sensor stabilization helps reduce motion blur handheld.

The WX1’s modest zoom range and slower autofocus hinder wildlife capture. It’s better suited for casual observations or less demanding subjects.

Sports Photography

Rapid action demands autofocus tracking and high fps. The A850’s 3 fps burst and 9-point AF system allowed rudimentary action capture in sports like local football games, but it revealed its age compared to modern bodies with expanded AF points and higher frame rates.

The WX1 cannot sustain sports shooting demands but offers a fun toy-like experience for kids’ events.

Street Photography

Raised points for the WX1’s small size, excellent portability, and silent operation. It allows candid, unintrusive shooting in urban settings. The A850’s weight and size make it less discreet but deliver superior image fidelity in available light.

Macro Photography

Neither camera specializes in macro, but the WX1 offers a close focusing distance of 5cm, making spontaneous close-ups easier. For the A850, dedicated macro lenses and focus stacking techniques produce better results but demand more equipment and setup.

Night and Astro Photography

The A850’s larger sensor and higher ISO capability let me push exposures further with less noise, critical for dim environments or star fields. Its long exposure capabilities and sturdy tripod mounting excel here.

The WX1’s high ISO performance is restricted; noise becomes pronounced above ISO 800. Night shots are heavily limited.

Video Capabilities

Neither camera prioritizes video. The WX1 records HD video at 1280x720/30fps without microphone input or stabilization options - adequate for casual clips, but limited.

The A850 lacks video recording entirely, focusing exclusively on stills.

Travel Photography

This is where each camera’s philosophy plays out. The WX1 is the classic grab-and-go camera - ultra-light, pocket-sized, ready at a moment’s notice. Great for travelers seeking convenience over absolute image quality.

The A850 demands more packing space and weight but returns immense flexibility and quality for serious travel photographers who prioritize image fidelity and lens choice over pocketability.

Ergonomics and User Experience

In controlled tests and field use, the A850’s robust buttons, dials, and logical menu hierarchy facilitated quick exposure adjustments and intuitive workflow. The dual memory card slots (CF and Memory Stick) enabled extended shooting sessions without swapping cards frequently.

The WX1’s streamlined interface and touchscreen absence simplify operation but limit customization. Battery life is shorter, and only one storage slot further restricts extended use.

Connectivity, Storage, and Battery

Connectivity options were minimal on both: no Wi-Fi, Bluetooth, or GPS. Both utilize USB 2.0 and HDMI output, facilitating basic transfers and external display capabilities. The A850 accepts CompactFlash and Memory Stick Duo cards with two slots, giving backup storage options, while the WX1 has a single Memory Stick slot and internal memory.

Battery life advantage goes to the A850, rated at about 880 shots per charge, sufficient for long outings. The WX1’s battery life information lacks official rating but is known to be moderately short, requiring spares for day-long travel.

Price-To-Performance and Value Assessment

The Sony A850, although discontinued, remains sought after in the used market for its full-frame sensor and image quality at affordable prices, often under $500. The WX1, a budget ultracompact, is readily available for less than $200, reflecting its entry-level positioning and compromises.

When weighing value, the A850 offers unbeatable image quality and flexibility for its price bracket, with the caveat of larger size and older technology (no live view, basic AF). The WX1 provides unmatched convenience and respectable daylight performance for casual shooters prioritizing pocketability.
