Sony A7 vs NEX-5: An Expert’s Take on Two Mirrorless Cameras from Different Eras

When Sony unleashed the Alpha A7 back in 2014, the mirrorless camera landscape got seriously shaken up. It was Sony’s first full-frame mirrorless camera, merging pro-level specs with a surprisingly compact body. Fast-forward a few years earlier, and Sony’s NEX-5 kicked off the brand’s E-mount journey with an entry-level, rangefinder-style mirrorless that catered to enthusiasts dipping toes into mirrorless systems.

If you’re here weighing the Sony A7 vs. NEX-5, you’re likely hunting for nuanced insights - past the spec sheets and marketing fluff. As someone who’s held, tested, and pushed thousands of cameras through their paces, I’m excited to unpack what these two cameras really bring to the table and how they stack up across popular photography disciplines and real-world use.

Let’s dive in.

How They Feel in Your Hands: Size, Ergonomics, and Controls

First impressions matter, and in this department, the Sony A7 and NEX-5 couldn't be more different.

The Sony A7 sports a robust SLR-style mirrorless body measuring roughly 127x94x48mm and tipping the scales at 474 grams. It feels solid - not heavy, but reassuringly substantial. That’s partly down to its all-metal construction and weather-sealed build, which gives the A7 a professional heft and durability you can rely on in suboptimal conditions.

In contrast, the NEX-5 is delightfully compact - 111x59x38mm and a featherlight 287 grams. Its rangefinder style, coupled with a minimalist control scheme, makes it pocketable and discreet. If inconspicuous street shooting or travel is your jam, this smaller footprint earns points.

Ergonomically, the A7 accommodates a deeper grip and a more extensive array of buttons and dials (its top view layout elaborated next) that suit hands-on, fast-paced shooting more comfortably. The NEX-5's smaller form factor means controls are more streamlined but less tactile, potentially less comfortable for prolonged use or with larger lenses.

The Battlefield of Buttons and Dials: Control Layouts Up Close

Looking down on both cameras showcases clear design philosophies.

The A7’s top deck offers dedicated dials for shutter speed and exposure compensation, a mode dial with locking mechanism, and a multifunction wheel - providing quick, intuitive access for manual control, a boon when every fraction of a second counts. On the NEX-5, the controls are pared back. A mode dial exists, but with fewer direct controls; shooting parameters often require menu diving.

This difference underscores the A7’s pro-orientation versus the NEX-5’s beginner-friendly design. If you love twiddling dials while shooting, the A7 feels more satisfying.

The Sensor Showdown: Size Matters

Let’s talk pixels and sensor tech because this is where the A7 asserts a massive lead.

The Sony A7 boasts a 35.8x23.9 mm full-frame CMOS sensor with 24 megapixels. That’s a whopping 855.62 mm² sensor area, dwarfing the NEX-5’s 23.4x15.6 mm APS-C sensor with 14 megapixels - 365.04 mm² area.

In real numbers, the A7 offers:

• Superior image resolution (6000x4000 vs. 4592x3056)
• Higher dynamic range (14.2 EV vs. 12.2 EV by DXOmark)
• Better color depth (24.8 bits vs. 22.2 bits)
• Improved low light sensitivity (ISO 2248 vs. 796 in DXOmark’s low-light ISO test)

This translates to cleaner images with richer tonal gradations and less noise, especially when pushing ISO or shadow recovery in post.

I’ve tested both cameras shooting identical scenes in low light. The A7’s images displayed smoother gradation and less chroma noise, making it a clear winner for demanding environments like dusk portraits or moody landscapes.

Wielding the Display - User Interface and Live View Experience

With all the photography you do now conducted through digital screens, how a camera presents itself visually during shooting matters.

The A7’s 3-inch Xtra Fine LCD tilting screen sports 1230k dots, giving crisp, bright live view and menu navigation. Tilting functionality aids shooting from creative angles - a significant plus.

The NEX-5’s 3-inch tilting display is less sharp at 920k dots and doesn’t quite match the A7’s vibrancy or clarity, but it gets the job done for casual framing.

Crucially, the A7 supplements LCD utility with its electronic viewfinder (EVF), sporting a 2359k-dot resolution with 100% coverage and 0.71x magnification - making compositions in bright sunlight or fast-moving scenarios easier. The NEX-5 lacks any EVF, so you’re reliant on the rear screen, which can struggle outdoors.

Face and Eye Detection Autofocus: How Smart Are These Cameras?

Autofocus (AF) can make or break the shooting experience. Especially with portraiture, having reliable face/eye detection that locks precisely onto your subject can save countless missed shots.

The A7 integrates Hybrid AF combining phase-detection and contrast detection, with a whopping 117 focus points (25 cross-type), and includes face detection. However, it lacks eye-AF for humans or animals - which Sony introduced in later models.

The NEX-5 uses contrast-detection AF only, with just 25 focus points and no face or eye detection support.

In real-world portraits, the A7’s AF locks noticeably faster and more confidently on faces, even in tricky light. The NEX-5’s slower, hunt-and-peck style contrast AF can miss fleeting expressions or lead to fuzzier eyes. For portraits, this is a strong point for the A7.

Capturing Beauty: Portrait Photography Results

Portraiture is often the ultimate test of a camera’s skin tone rendering, bokeh quality, and autofocus precision.

Thanks to its full-frame sensor and superior lens mount compatibility, the A7 excels with richer, more natural skin tones and smoother background separation thanks to shallower depth of field. The built-in 117-point phase-detect AF provides better face detection and holding focus.

The NEX-5, while capable with bright prime lenses, delivers portraits with slightly more pronounced noise and less creamy bokeh due to the smaller sensor and lower resolution output. Also, slower AF tracking can miss subtle expressions or eye movement.

Landscape Photography: Dynamic Range and Ruggedness

For landscapes, resolution and dynamic range top the wishlist, along with weather resistance.

The Sony A7’s 24MP sensor and 14+ stops of dynamic range enable capturing broad tonal gradients from bright skies to shaded foliage with exquisite detail. The camera’s environmental sealing shields it from dust and moisture - critical for outdoor shooting in challenging conditions.

The NEX-5, with its 14MP APS-C sensor and 12+ stops dynamic range, still produces respectable landscapes but falls short on fine detail and highlight retention. The lack of weatherproofing means caution is needed outdoors.

Thus, for serious landscape shooters wanting that “wow” image fidelity and the confidence to shoot in rain or mist, the A7 is better suited.

Wildlife and Sports: Speed, Autofocus, and Burst Performance

If you chase wildlife or cover sports, performance specs like AF speed, burst rate, and tracking accuracy matter immensely.

The A7 shoots at a conservative 5 fps continuous burst, with reliable phase-detection AF tracking on 117 points. However, its AF system - while solid for the era - is no match for modern beasts in subject tracking finesse.

The NEX-5 surprisingly has a faster 7 fps burst rate but relies solely on slower contrast-detection AF and only 25 points, limiting subject tracking in challenging conditions.

Across multiple testing scenarios - bird photography at dawn, soccer matches - the A7’s quicker, precise AF tracking, and full-frame sensor’s better low-light sensitivity won out in producing usable frames.

Street and Travel: Size, Discretion, and Battery Life

Street photography demands portability, unobtrusiveness, and quick responsiveness.

Here, the NEX-5’s slim rangefinder style and light weight score big, allowing you to wander city streets unnoticed. Its lack of an EVF requires adjusting to screen shooting but favors discretion.

The A7’s bigger body and EVF add presence but improve framing accuracy. The tilting screen helps low-angle street shots.

Battery life is comparable - 340 shots per charge for A7 vs. 330 shots for NEX-5 - both decent but requiring spare batteries for day-long use.

Travel photographers balancing image quality and portability might lean toward the A7 for better images or the NEX-5 for lighter, more stealthy shooting.

Macro Photography: Magnification and Focus Precision

Neither camera specializes in macro out of the box, but sensor size influences detail capture.

The A7’s full-frame sensor offers better resolution for cropping close in post. Its 117-point hybrid AF focuses accurately, which helps with fine detail.

The NEX-5’s APS-C sensor yields a 1.5x crop factor, theoretically boosting reach with macro lenses but with a sacrifice in native resolution.

Neither supports focus stacking or bracketing. For precise macro focusing, the A7’s manual focus aids and focus peaking tools give it an edge.

Night and Astrophotography: High ISO and Exposure Control

Low-light and night photography are demanding testbeds for sensor noise, ISO performance, and exposure options.

The A7’s max native ISO of 25,600, coupled with excellent low-light handling (DXO low-light ISO score: 2248), permits cleaner handheld shots in dim scenes. Its 14 stops dynamic range allow recovering shadow detail post-capture.

The NEX-5 maxes at ISO 12,800 and shows visible noise earlier (DXO score: 796), limiting usability at high ISO, especially for astro.

The A7 also supports custom white balance bracketing and has more flexible shutter speed range (up to 1/8000 sec), aiding long exposures necessary for star trails.

Video Capabilities: Resolution, Audio, and Stabilization

Video-wise, both cameras shoot Full HD 1080p, with the A7 offering 60p and even 60i, while the NEX-5 offers 60fps but fewer frame options overall.

The A7 includes microphone and headphone ports - key for serious videographers seeking control over audio monitoring. The NEX-5 lacks them, which is a limiting factor.

Neither offers in-body image stabilization (IBIS), so stabilization depends on lenses or external rigs.

Overall, the A7’s video features provide more flexibility for hybrid shooters doing both stills and video.

Professional Workflow: Reliability, Formats, and Lens Ecosystem

Both cameras shoot RAW, giving post-processing control. However, the A7’s 14-bit RAW files carry more detail and latitude compared to the NEX-5’s 12-bit RAWs, offering pros more editing freedom.

Sony’s E-mount lens ecosystem is vast, and both can mount the same lenses, but full-frame lenses are optimized for the A7’s sensor. Using APS-C lenses on the A7 invokes a cropped sensor mode, losing resolution.

Build quality favors the weather-sealed A7 for professional use outdoors or in demanding jobs. The NEX-5 feels more consumer-grade, suited for casual or enthusiast use.

Connectivity and Battery: Modern Conveniences

The A7 boasts built-in wireless connectivity with NFC, HDMI output, and USB 2.0 ports. It supports Sony’s PlayMemories apps for time-lapse and remote control.

The NEX-5 lacks wireless features and Bluetooth, relying only on HDMI and USB 2.0, which feels dated today.

Battery models are identical (Sony NP-FW50), but the A7 draws more power due to its EVF and processing.

Pricing and Value: What Will It Cost You?

On release, the A7 landed at $798 body-only, whereas the NEX-5 was $599.

Given the major sensor and feature upgrades, the A7’s higher price is justified.

In today’s market, both are available used at lower prices. For photographers prioritizing image quality and durability, investing slightly more in a used A7 pays off.

How Do They Stack Up Overall?

Based on extensive hands-on testing, here’s a broad strokes comparison:

• Image Quality: A7 decisively better
• Autofocus: A7 faster and more accurate
• Build & Weather Sealing: A7 robust; NEX-5 beginner-grade
• Size & Portability: NEX-5 more compact
• Video: A7 more flexible outputs and audio support
• Battery: Comparable
• Price: NEX-5 cheaper but dated
