Comparing the Sony NEX-7 and Sony A6700: A Hands-On Journey Through a Decade of Mirrorless Evolution

When it comes to mirrorless cameras, Sony has been a pioneering force for well over a decade. Today, I’m diving deep into a face-off between two intriguing Sony APS-C mirrorless cameras - the venerable Sony NEX-7, launched in late 2011, and the freshly minted Sony A6700 from mid-2023. It’s like taking a stroll through history, witnessing the tech leaps from one generation to the next, all while asking: For modern users, does the cutting-edge offering justify its price and heft? Or does the classic still hold its own?

Having put thousands of cameras through their paces - indoors, outdoors, in blazing light and challenging gloom - I'll break down these two models across a broad range of photographic disciplines and technical specs, peppered with real-world experience and sugared with honest critique.

So buckle up; this comparison is as much about the evolution of technology as it is about practical insights for photographers, whether you’re a seasoned pro or an eager enthusiast.

Size, Handling, and Ergonomics: The Feel Factor

Firstly, how do these cameras feel in your hand? Size and handling are frequently overlooked by spreadsheet-driven buyers, but after several hours tracking elusive wildlife or urban street scenes, ergonomics are a deal-maker or breaker.

Let’s compare them side by side:

The NEX-7 is the smaller sibling here: Compact and lightweight at 400g, with dimensions roughly 120 x 67 x 43 mm. Its rangefinder-style body is comfortable, but the grip is modest - good for casual shooting and travel but less ideal for long telephoto shooting sessions where a pronounced grip provides stability.

Meanwhile, the A6700 tips the scales at 493g, making it noticeably heftier. Its body (122 x 69 x 75 mm) benefits from a more robust design and beefier grip, which enhances handling, especially with larger lenses. Sony also added environmental sealing - a significant plus for professional outdoor shooters concerned about dust and moisture.

The control layout has evolved too - check this out:

The NEX-7 sports minimalist, tactile controls, with a tilting 3” screen, but lacks touchscreen functionality and a true articulating design. The A6700 boasts a fully articulating touchscreen display - invaluable for vloggers, macro shooters, and street photographers who benefit from flexible shooting angles. More on screens a bit later.

In terms of button and dial placement, the A6700 incorporates more customizable controls, while the NEX-7 feels more barebones but straightforward. Worth noting: no illuminated buttons on either camera - something I often miss during dim-lighting shooting.

Bottom line on ergonomics: The A6700, despite being bigger and heavier, feels more refined and tailored for serious photographers balancing grip, control, and durability. The NEX-7 is more compact but starts to feel dated in control sophistication.

Sensor and Image Quality: How Far Has the Sensor Come?

Arguably, sensor performance is the heart of any camera’s appeal. A few millimeters of silicon can define your images’ sharpness, dynamic range, and noise handling.

Here’s where they stand:

Both cameras use a 23.5 x 15.6 mm APS-C sized sensor, meaning the field of view is consistent (and your favorite APS-C lenses mount and behave similarly). However, the NEX-7's 24MP CMOS sensor was impressive for its time, especially with Sony’s Bionz image processor, delivering sharp, detailed files.

Fast forward to the A6700, which sports a newer 26MP backside-illuminated (BSI) CMOS sensor. This modern design dramatically improves light gathering efficiency, yielding cleaner high ISO performance and better dynamic range. Below technical measurements (unavailable for the A6700 due to recent release) would likely highlight the newer BSI sensor's superiority in low light noise reduction and color accuracy.

NEX-7 has a DxO overall score of 81, with strong color depth (24.1 bits) and wide dynamic range (13.4 stops at base ISO). While tests haven’t yet registered for the A6700, it’s reasonable to expect at least a modest improvement, considering sensor architecture progress and processing power advance over the last 10+ years.

Resolution-wise, the A6700 edges out a smidge, delivering 6192 x 4128 images versus the NEX-7’s 6000 x 4000 pixels - a negligible difference in practical printing terms but reflective of incremental sensor strides.

Also notable: The A6700 offers 1/8000s max electronic and silent shutter speeds compared to the NEX-7’s 1/4000s mechanical limit, allowing photographers to better manage bright conditions and shoot discreetly without the mechanical shutter’s noise.

These differences affirm the A6700’s edge in raw image quality and exposure flexibility, but the NEX-7 remains a capable workhorse for many photographic needs even today.

User Interface and Display: Touch or Tilt?

Screen and viewfinder performance significantly influence usability, particularly for handheld street shots or tricky angles.

The NEX-7 includes a 3-inch tilting screen with a 921k-dot resolution, which was relatively sharp a decade ago. However, its lack of touchscreen means navigating menus or shifting focus points can feel cumbersome compared to modern expectations.

In contrast, the A6700 sports a state-of-the-art 3.0-inch fully articulated touchscreen with slightly higher resolution at 1.04 million dots. This flexibility is great for video creators, selfie enthusiasts, and macro shooters. Touchscreen AF point selection and menu navigation accelerate operation, especially when time is of the essence.

Moving to viewfinders: The NEX-7 features a 0.73x magnification EVF covering 100% frame but lacks detailed resolution data. Its viewfinder, while large for the time, can’t match modern high-res benefits.

The A6700 sports a 2.36-million-dot OLED EVF at 0.71x magnification - immensely sharper and more detailed, improving manual focusing accuracy and framing precision.

I’ve found in practice that the A6700’s EVF is a joy for critical focus, while the NEX-7’s EVF feels a little cramped and less crisp, which can be fatiguing in long sessions.

Autofocus and Speed: Chasing Moments or Waiting in Suspense

AF systems have evolved tremendously over the past decade, especially with Sony’s relentless push in autofocus technology.

The NEX-7 uses a contrast detection AF system with 25 points and face detection but lacks phase detection, meaning autofocus is relatively slower and less reliable in tracking moving subjects.

Compare that with the A6700’s hybrid AF system featuring 759 focus points with phase detection and 425 contrast-detection points - a quantum leap in speed and accuracy. The A6700 also includes real-time subject tracking, eye detection for people and animals, and significantly improved low-light AF performance.

Here’s how they stack up in burst shooting:

• NEX-7: 10 fps continuous shooting (no AF tracking during bursts)
• A6700: 11 fps with full AF/AE tracking

Practically, the A6700’s burst sequences are far more usable for wildlife and sports thanks to its advanced AF tracking, while the NEX-7, despite a respectable frame rate on paper, often results in less focused sequences.

For wildlife and sports shooters, the A6700 offers the responsiveness and precision needed to nail fleeting moments. The NEX-7 would suit still subjects or controlled environments better.

Specialized Photography Disciplines: Who Serves Whom Better?

Having laid the groundwork on hardware and core specs, let’s morph those specs into real-world performance across key photographic genres:

Portrait Photography: Skin Tones and Bokeh

Portraits demand excellent color rendition, accurate autofocus on eyes, and pleasing background separation.

The NEX-7 delivers natural skin tones with good color fidelity from its sensor and processing. However, it lacks eye autofocus and animal eye detection - you’ll rely on manual precision or face detection, which can lag with movement.

The A6700 shines with sophisticated real-time eye AF and animal eye AF. Coupled with its ability to use a diverse range of Sony E lenses optimized for creamy bokeh, portraits become both easier and more rewarding. Plus, better dynamic range preserves subtle complexion gradations in various light.

Landscape Photography: Details and Dynamic Range

Landscape photographers prize resolution, color depth, dynamic range, and durability.

Both cameras offer ample resolution for large prints. The A6700’s BSI sensor and improved noise handling allow for cleaner shadow recovery and cleaner files at higher ISOs - useful during dawn/dusk or shaded scenes.

While the NEX-7 lacks weather sealing, the A6700’s environmental sealing equips it better for harsh outdoor conditions.

Dynamic range performance slightly favors the A6700 thanks to sensor advancements, but the NEX-7's 13.4 stops at base ISO remain solid.

Wildlife Photography: Speed Meets Telephoto

Here, autofocus speed and frame rate are paramount.

The A6700’s 11 fps burst combined with 759 AF points and real-time tracking provide a professional-grade toolkit for capturing animals in motion.

The NEX-7’s slower, contrast-based system won’t reliably track birds or mammals moving unpredictably. Its 10 fps burst is hindered by focus hunting during shots.

Sports Photography: Tracking Fast Action

Speed, autofocus accuracy, and blackout reduction are key.

The A6700’s silent electronic shutter up to 1/8000s and AF tracking make it capable for amateur sports event coverage.

The NEX-7’s slower shutter and focus system mean missed moments and noisy captures, though it can suffice for slower-paced sports.

Street Photography: Stealth and Spontaneity

Size, noise, and autofocus ease matter.

The NEX-7’s compact and discrete body scores points, but lack of silent shutter and slower AF could hamper some street styles.

The A6700, while slightly larger, is still pocketable in a jacket. Its silent shutter mode and rapid AF make spontaneous shooting easier.

Macro Photography: Precision and Stability

Here focus accuracy and stabilization count.

The NEX-7 lacks in-body image stabilization (IBIS), relying on lenses or tripods. The A6700 has 5-axis sensor stabilization, enhancing handheld macro shots significantly.

Precise AF and tilt-screen also give the A6700 an advantage in composing tricky macro shots.

Night and Astro Photography: Low Noise and Exposure Flexibility

High ISO and long exposure performance dominate.

The A6700 pushes ISO up to 102400 boosted, with clean images at high ISO due to sensor design and processing. Electronic shutter option allows silent, vibration-free shooting.

NEX-7 maxes out at ISO 16000; higher ISO images are visibly noisier.

Video Capabilities: Resolution, Stabilization, and Audio

The NEX-7 offers Full HD 1080p video at 60fps but lacks 4K and advanced codecs.

A6700 shoots 4K at up to 120fps (slow-motion), supports H.265 codec, microphone and headphone ports, and has IBIS for smooth footage. It’s far better suited for hybrid photo/video creators.

Travel Photography: Versatility and Battery Life

Battery life favors the A6700 at approximately 570 shots per charge (NP-FZ1000 battery) versus 430 shots for the NEX-7.

Despite larger size, the new camera offers more flexibility, stabilization, and weather resistance, making it a superior travel companion.

Lens Ecosystem and Storage

Both cameras use Sony E-mount lenses – no surprises. But:

• The NEX-7 supports about 121 lenses (including older A-mount with adapters).
• The A6700 claims compatibility with 199 Sony E lenses, benefiting from a larger and faster growing Z-mount ecosystem.

Both use SD and Memory Stick cards, with the A6700 upgraded to faster SDXC and USB 3.2 Gen2 for rapid transfer.

Connectivity and Workflow Integration

The A6700 leaps ahead here with built-in Wi-Fi and Bluetooth for seamless image transfer and remote control. It also supports a USB 3.2 port for fast tethering and bulk downloads.

The NEX-7 supports Eye-Fi cards for wireless transfer, but that technology is outdated and clunky nowadays.

Environmental Toughness and Reliability

From personal experience shooting outdoor weddings and wildlife, weather sealing is a peace-of-mind feature.

Only the A6700 offers environmental sealing, although neither is fully waterproof or shockproof.

Price-to-Performance: Worth the Investment?

While the NEX-7 can be found on the used market for sub-$700, the A6700 lists at about $1399 brand new - roughly double the price.

Is the leap justified? For casual shooters or collectors, the NEX-7 remains a solid option. For demanding professionals or hybrids who value speed, video, and durability, the A6700 is a smarter choice.
