Sony A7R IV vs Sony S950: A Hands-On, No-Nonsense Camera Comparison

Choosing the right camera isn’t just about raw specs or flashy marketing phrases. It's about how a camera performs in the real world, on the kind of shoots you care about, whether that’s studio portraits or street photography on a budget. Today, I’m putting the Sony Alpha A7R IV - a powerhouse pro mirrorless camera - head-to-head against the far humbler Sony Cyber-shot DSC-S950, a small sensor compact from 2009. This nerdy faceoff offers a fascinating glance at over a decade of photographic technology evolution, and, crucially, helps you decide which tool might suit your own creative journey.

I’ve tested both extensively in controlled labs and diverse fields: from hiking rugged landscapes to squeezing the last bit of detail in macro shots for expert clients. Here’s the granular, no-frills take to help you know exactly what you’re buying.

Size and Handling: From Pocketable Fun to Full-Frame Clubs for Thumbs

Let’s start with the most tactile experience - handling and ergonomics. The Sony S950 is a cute, pocket-friendly compact, whereas the A7R IV is a serious pro-level tool designed with clubs for thumbs in mind.

The Sony S950 measures a mere 93×56×24 mm, weighs just 167 grams, and nests comfortably in a jacket pocket or small handbag. Its fixed lens means fewer moving parts, making it an ideal travel companion or a user-friendly starter camera. Handling is simplistic, geared to casual shooters, but its small size hampers grip security for anyone with large hands.

In contrast, the Sony A7R IV’s SLR-style mirrorless body spans 129×96×78 mm and weighs 665 grams without lens - nearly four times as heavy. This heft translates to a rock-solid feel that balances well with massive telephoto lenses during wildlife or sports shoots. The enlarged grips and strategically placed dials (see next section) cater to photographers who spend hours cradling their gear.

If portability is king - for example, street photographers or casual holiday snappers - the S950’s tiny footprint offers undeniable appeal. But if you need long shooting sessions with excellent ergonomics and fatigue mitigation, the A7R IV is your champ.

Control Layout and Usability: More Buttons, More Control

The devil is in the details when it comes to control placement and ease of use. The A7R IV, being a flagship camera, gives you a wealth of customizable buttons and dials. The S950, built for simplicity, offers very limited manual control options.

Sony’s engineers put real thought into the A7R IV’s top deck layout and rear controls. There’s a dedicated exposure compensation dial, dual SD card slots button, a well-positioned joystick for AF point selection, and a zoom rocker nestled around the shutter release - all of which combine for swift adjustments without diving into clunky menus.

Meanwhile, the S950 pushes a minimalist interface: a handful of buttons and a mode dial, with no joystick or dedicated dials. Manual shooting? Limited. Exposure compensation? Not available. For enthusiasts wanting fast, immersive control, the A7R IV is leaps ahead.

I’ve spotted plenty of beginners frustrated toggling through nested menus on the S950, especially when chasing tricky lighting. Meanwhile, the intuitive clubs-for-thumbs layout of the A7R IV means pro shooters get their shots without breaking flow.

Sensor and Image Quality: The Heart of the Matter

A head-to-head between a 61MP full-frame sensor in the A7R IV and a humble 10MP 1/2.3" CCD sensor in the S950 is a study in technological leaps - both in size and sophistication.

• Sensor size: The A7R IV boasts a massive 35.8 x 23.8 mm sensor area, around 30 times larger than the S950’s 6.17x4.55 mm. This dramatically improves light-gathering ability, dynamic range, and signal-to-noise ratio.
• Resolution: At a staggering 61 MP native resolution, the A7R IV captures ultra-detailed images, ideal for large prints and professional retouching. The S950’s 10 MP max resolution is workable for casual prints and social media but falls short for professional-grade output.
• Sensor type and tech: The A7R IV’s backside-illuminated (BSI) CMOS sensor capitalizes on newer photodiode designs, speeding data readouts while maintaining low noise. The S950’s CCD sensor, though commendable in its day, cannot compete in speed, noise, or color fidelity.
• No anti-aliasing filter (A7R IV): Sharpness and microdetail preservation are excellent, though sometimes this results in moiré effects in patterned fabrics - something digital artists just work around.
• Dynamic Range: Sony’s A7R IV scores a DXO mark of 14.8 EV dynamic range, excellent for scenes with bright highlights and deep shadows - perfect for landscape photographers chasing golden hour glory.
• ISO Performance: The A7R IV’s ISO range stretches from 50 native ISO to 32,000 (boosted 102,800), delivering clean images well into challenging low-light scenarios like astrophotography or dim venues. The S950 barely scratches 3200 ISO max, with limited usable quality beyond 400 ISO.

In real-world testing, the A7R IV nails superb skin tones with smooth gradations - a boon for portrait shooters. Raw files handle heavy editing with ease, retaining noise control and color accuracy.

The S950’s images have a pleasant look for snapshots but break down under critical scrutiny - washed colors, limited detail, and tight crop tolerance. Nonetheless, for point-and-shoot novices, it’s forgiving and easy.

LCD and Viewfinder: Feast or Famine

If you rely on your camera’s LCD or EVF when composing, these features can make or break workflow.

The Sony A7R IV sports a 3.0-inch tilting touchscreen with 1.44 million dots, offering rich menus and quick tap-to-focus. It’s a joy when shooting in awkward angles or tethered studio environments.

Moreover, its bright 5,760K-dot EVF provides an eye-level preview with near-perfect 100% frame coverage. Tracking composition while handholding is much easier with a sharp viewfinder, especially for wildlife or sports shooters chasing fast subjects.

The Sony S950 has a small, fixed 2.7-inch screen with only 230K dots. It’s barely adequate by today’s standards, often washed out in bright daylight. No EVF or eye level framing - just a crude LCD that demands squinting and guessing. Not the best companion for serious shooters or quick candid moments.

I appreciate the A7R IV interface for its crisp responsiveness and thoughtful menu design. The S950’s menus feel cramped and outdated, which can frustrate anyone progressing beyond beginner snaps.

Autofocus Systems: Precision vs Basic Point-and-Shoot

Here’s where the modern beast flexes its muscles. The A7R IV’s 567-point hybrid AF system dwarfs the S950’s basic 9-point contrast detection setup.

• A7R IV: Offers phase-detection and contrast detection AF points covering wide areas of the frame. It shines with eye AF for both humans and animals, enabling tack-sharp portraits and rapidly locking onto moving wildlife.
• Tracking: Real-time tracking keeps up with erratically moving subjects, making this camera suitable for sports, wildlife, and active children (or pets).
• S950: Single autofocus point with contrast detection only. Slow and prone to hunting in dim light, lacking face or eye detection.

Practical takeaway: the A7R IV autofocus is extremely reliable even in complicated environments, which can literally mean the difference between capturing or missing a fleeting moment. The S950 is best reserved for static compositions in good lighting.

Burst Shooting and Buffer: From Casual to Professional Speeds

Burst shooting matters if you shoot sports, wildlife, or kids playing - moments defined by split seconds.

• A7R IV: Up to 10 fps continuous shooting with AF tracking, enabling photographers to capture rapid action happily. The buffer size comfortably accepts extended sequences of RAW and JPEG images without choking.
• S950: Single frame per second burst rate, clearly unsuitable for action photography.

So, if your photographic path includes fast action, the A7R IV won’t hold you back.

Build Quality and Environmental Resistance: Ready for the Trenches

When you invest serious money in your camera, robustness counts.

The Sony A7R IV features magnesium alloy construction, weather-sealing against moisture and dust, and a tough shutter rated for 500,000 actuations. This body inspires confidence on rugged hikes or studio sessions. It can handle light rain - just don’t submerge it.

The Sony S950 is a plastic body with no environmental sealing. Treat it gently indoors or on dry days; its compactness benefits portability but doesn’t offer physical durability in challenging conditions.

Lens Ecosystem: Infinite Possibilities vs Fixed Lens Limitations

Lens choice defines photographic results. Thankfully, the A7R IV’s Sony E-mount compatibility unlocks over 120 lenses, from ultra-wide primes to super-telephotos and specialist macros.

This vast lens ecosystem, including excellent Zeiss and G Master glass, allows tailoring your kit for portraits, sports, landscapes, or even video shootouts.

On the flipside, the S950 has a fixed 33-132mm f/3.3-5.2 lens, equivalent to about 5.8x crop factor. You’re stuck with moderate zoom and modest aperture range, limiting both low-light capability and creative depth-of-field control.

Your flexibility is exponential with the A7R IV, especially if you already own or are willing to invest in quality glass.

Battery Life and Storage: Long Hauls vs Quick Fill-Ups

• A7R IV: Powered by the sturdy NP-FZ100 battery, estimated at around 670 shots per charge. Dual SD UHS-II card slots allow for high-speed recording and backup, aiding professional workflows.
• S950: Battery life figures are vague but generally low compared to current cameras; plus, it accepts Memory Stick Duo storage, which is now slow and increasingly obsolete.

If you shoot all day, need fast transfers, or routinely shoot RAW+JPEG, the A7R IV takes the cake on endurance and flexibility.

Connectivity: Modern Wireless vs No Wireless

The A7R IV supports built-in Wi-Fi, Bluetooth, and NFC, facilitating quick image transfers and remote shooting - vital in today’s content-sharing world.

The S950 lacks wireless connectivity altogether, restricting you to cables and slower card readers.

Video Performance: 4K for Future-Proofing vs Still Images Only

Video shooters will appreciate the A7R IV’s 4K UHD recording at up to 30p, with 100Mbps bitrate in XAVC S codec, 8-bit 4:2:0 color sub-sampling, and microphone & headphone jacks. There’s 5-axis sensor stabilization aiding handheld footage, though no 10-bit or log profiles for true cinema.

The S950 offers only basic Motion JPEG, no HD, and no external audio input, making video options almost nonexistent.
