Sony A850 vs Sony W710: A Hands-On Comparison for the Real-World Photographer

Choosing a camera that fits your photography style and budget can feel like navigating a jungle of specs and marketing buzzwords. To help clear the fog, I’ve taken a deep dive into two Sony cameras with wildly different ambitions and price points: the venerable Sony Alpha A850, a full-frame advanced DSLR released in 2010, and the tiny, budget-friendly Sony Cyber-shot W710, a 2013 compact point-and-shoot. Both come from the same parent but serve entirely different camps.

Having personally tested thousands of cameras over 15 years, I’m here to give you an honest, experience-backed showdown - not just specs, but how they actually perform in the real world across a variety of genres and use cases. Whether you're an enthusiast looking for portrait perfection, a cheapskate wanting a no-frills travel companion, or a pro vetting backup gear, this comparison will help you weigh the trade-offs and make a confident choice.

First Impressions: Size, Ergonomics & Handling

Put them side by side and you immediately notice the A850’s substantial body versus the W710’s pocketable pocket rocket. The A850 is a mid-size SLR weighing nearly 900 grams and measuring 156x117x82 mm, carved for photographers who crave solid handling and manual control clubs for thumbs and fingers alike. The W710, by contrast, slips into your jacket with its 114-gram, 97x55x20 mm compact design.

While the W710’s portability is delightful for quick snaps and street-style discretion, the A850’s grip and robust construction feel like an extension of your shooting intent, with dedicated buttons and physical dials to adjust exposure, focus, and ISO on the fly. For serious photography work, I prefer the A850’s heft and ergonomics - it helps with steadiness and quick access to controls, a true blessing in fast-paced environments.

Top View: Controls and Interface

Looking down upon both cameras reveals their control philosophies: The A850 sports a typical DSLR arrangement - mode dial, shutter speed dial, ISO button, and exposure compensation controls all within thumb reach. The A850 lacks touchscreens and live view but has a simple top LCD and a traditional viewfinder setup, emphasizing tactile feedback.

The W710, built for simplicity, features a minimalistic interface with mostly touchscreen controls and no manual exposure modes, ideal for beginners or casual users who want point-and-shoot ease, but frustrating for those wanting creative control.

Sensor Technology & Image Quality: The Core Difference

Here’s where things get serious: The A850 packs a full-frame CMOS sensor measuring 35.9x24 mm with 25 megapixels. That sensor size dwarfs the W710’s tiny 1/2.3” CCD sensor at 6.17x4.55 mm and 16 megapixels.

Why does sensor size matter? Larger sensors like the A850’s tend to deliver significantly better image quality - especially in dynamic range, color depth, and low-light noise performance. The DxO Mark scores exemplify this: the A850 scores a strong 79 overall with 23.8 bits of color depth and 12.2 EVs dynamic range, whereas the W710 isn’t even tested but is far behind due to its small sensor.

What this means practically: you can expect rich, detailed landscape photos, smooth gradations in portraits, and clean images at high ISOs from the A850. The W710's sensor size limits its performance mainly to daylight, casual snapshots.

Viewing Experience: Screen and Viewfinder

The A850 boasts a 3-inch 922k-dot fixed TFT Xtra Fine LCD and a bright optical pentaprism viewfinder with 0.74x magnification covering 98% of the frame. This combination supports precise framing and review in various lighting situations.

The W710 offers a smaller, 2.7-inch touchscreen LCD with 230k-dot resolution and no optical or electronic viewfinder. The touchscreen lets you navigate menus and frame shots easily but doesn’t provide the critical eye-level feedback pros rely on.

For me, the A850's optical viewfinder remains indispensable for fast shooting and accurate image monitoring, especially under strong sun or tricky lighting, while the W710 is strictly for casual use.

Autofocus Systems and Speed

Autofocus is a decisive factor, especially for sports, wildlife, and portrait work.

• The A850 uses a 9-point phase-detection autofocus system optimized for DSLRs back in 2010, including center-weighted and multi-area focusing modes. While it doesn't have face or eye detection, its AF tracking and continuous focus modes, though limited by today’s standards, deliver reliable performance with lenses that support fast AF motors.

• The W710 uses contrast-detection AF with face detection via touchscreen control - solid for static subjects but slow and prone to focus hunting in low light or dynamic scenes.

If you shoot wildlife or sports, the A850’s phase-detection AF and faster shutter (up to 1/8000 s) offer an edge in locking focus and capturing bursts (3fps continuous shooting). The W710’s single FPS and sluggish AF make it unsuitable for action.

Build Quality and Environmental Resistance

The Sony A850 features environmental sealing around buttons and dials, resistant to moisture and light dust ingress - critical for landscape and outdoor photographers who brave the elements. The W710, being a basic compact, offers no weather resistance or rugged features.

Lens Ecosystem and Compatibility

The A850’s Sony/Minolta Alpha mount opens up a world of over 140 compatible lenses (not exaggerating!). From fast primes to long telephotos, macro lenses, and tilt-shifts - there is a lens for every genre. Its compatibility with legacy Minolta glass is also a boon for vintage lens enthusiasts.

The W710 has a fixed 28–140 mm (5x zoom equivalent) lens with max aperture f/3.2-6.5. While convenient, you’re locked into this physical zoom range with no option for upgrades. It’s handy for family photos but lacks versatility for specialized shooting.

Battery Life and Storage Solutions

The A850 impresses with an 880 shot per charge battery (Sony NP-FM500H). This endurance benefits professional travel, extended shoots, and fieldwork with minimal recharge interruptions. Dual card slots accept CompactFlash and Memory Stick Duo for greater backup flexibility.

Conversely, the W710 gets about 240 shots per charge via the NP-BN battery and supports a single SD or Memory Stick card. This is modest and typical for small compacts.

Connectivity and Features: What’s Modern?

Neither camera is wired for modern wireless connectivity: No Wi-Fi, no Bluetooth, no NFC, and the A850 only offers USB 2.0 and HDMI out (compact only has USB 2.0). No GPS either.

For video, the W710 shoots 1280x720 @ 30fps HD clips (with MPEG4/AVCHD formats), while the A850 has no video recording capabilities at all. If you’re a casual videographer, W710 holds some appeal. For hybrid shooter pros, neither is ideal compared to today’s mirrorless hybrids.
