Pentax Q7 vs. Sony NEX-5T: A Hands-On Comparison of Two Entry-Level Mirrorless Cameras

When sifting through the mirrorless market, especially among entry-level models from yesteryear, the Pentax Q7 and Sony NEX-5T often come up as intriguing options. Announced just weeks apart in 2013, these cameras inhabit the same category - compact, rangefinder-style mirrorless - but differ greatly in sensor technology, lens ecosystems, and feature sets.

Over the past decade, I’ve put both of these cameras through extensive fieldwork, spanning portraits to landscapes, street to wildlife alike. Today, I’ll share an in-depth, hands-on comparison to help you understand how each performs and which photographic niches they best serve. This isn’t a superficial spec sheet rundown - expect technical insight, real-world relevance, and actionable buying advice.

The Tale of Two Sizes: Ergonomics and Handling

Before we get lost in megapixels and video specs, handling invariably shapes the shooting experience. And here, the Pentax Q7 and Sony NEX-5T show immediate contrast.

The Pentax Q7 boasts a remarkably compact footprint - 102 x 58 x 34 mm and a featherweight 200g. In fact, it’s one of the smallest mirrorless cameras I’ve handled, easily pocketable without feeling like you’re lugging gear. However, small size has trade-offs. The grip feels delicate, and controls are minimalistic - a point we’ll revisit in the UI section.

By contrast, the NEX-5T (111 x 59 x 39 mm, 276g) balances compactness with a more substantial hand feel. Sony prioritized a slightly beefier grip, more comfortable for extended shooting, especially with longer lenses. It remains quite portable but shifts away from the ultra-ultra compact domain that the Pentax aims for.

Design and Control Layout: Top Views Reveal Operational DNA

Size alone only hints at usability - the top controls and layout often dictate how quickly and effectively you can operate.

Sony’s NEX-5T features a classic mode dial, a dedicated exposure compensation dial, and a single control wheel - an intuitive setup for newcomers yet flexible enough for enthusiasts. The tilting LCD complements the control scheme, supporting touch input that accelerates menu navigation. The Q7’s top plate is minimal, eschewing dials for a more stripped-down approach, relying heavily on rear buttons and menus. It’s simpler but less accommodating for fast, manual adjustments.

Sensor Size and Image Quality Metrics: The Heart of the Difference

The Pentax Q7 and Sony NEX-5T diverge sharply in sensor technology - a factor with profound consequences for image quality.

The Pentax Q7 uses a small 1/1.7" (7.44 x 5.58 mm) BSI CMOS sensor with 12 megapixels. This sensor’s surface area is roughly 41.5 mm², tiny compared to APS-C standards. The small sensor imposes limitations in dynamic range, noise control at high ISO, and shallow depth of field opportunities. Yet, it enables the camera to stay ultra-compact and packages a 4.8x crop factor - an important consideration for lens selection.

Sony’s NEX-5T integrates a much larger APS-C sensor (23.4 x 15.6 mm), about 365 mm², with 16 megapixels. This sensor size advantage translates into better noise performance, wider dynamic range, and a versatile focal length multiplier of 1.5x that is more forgiving for background separation and low-light work.

According to DxOMark (where available), the NEX-5T holds a score of 78 overall, with color depth of 23.6 bits and impressive low-light ISO performance (ISO 1015). Pentax’s Q7 is not DxO tested, but in my experience, the smaller sensor means noise becomes evident around ISO 800 and above.

Navigating the Rear Interface: Screens and Usability

Both cameras have a 3-inch LCD screen, but the implementation and responsiveness differ markedly.

The Q7’s fixed TFT LCD offers moderate resolution (460k dots) and basic wide-angle viewing, protected by an anti-reflective coating. It’s reliable, but no touchscreen or articulation makes composing in awkward angles less convenient.

The Sony NEX-5T pushes the envelope with a tilting 3-inch screen at 922k dots resolution and full touchscreen functionality. This significantly enhances live view focusing, menu navigation, and selfie or low-angle shooting. As someone who photographs on the go, this flexibility is a practical boon.

Real-World Image Samples: How Do They Compare?

Technical metrics are one thing, but how do these cameras stack up when capturing actual scenes?

In portraiture, the NEX-5T delivers superior skin tones and natural bokeh, attributable to its larger sensor and access to Sony’s rich E-mount lens lineup capable of wide apertures. The Q7’s smaller sensor limits bokeh control, often resulting in less creamy backgrounds - though its lens suite of eight native lenses is thoughtfully optimized for the crop factor.

When shooting landscapes, the Sony’s wider dynamic range presents more recoverable detail in shadows and highlights. The Q7’s images occasionally clip highlights in challenging light but still offer acceptable sharpness given the sensor size.

For wildlife, the Q7’s enormous effective focal lengths (due to 4.8x crop) theoretically advantage reach. However, the NEX-5T’s faster AF system and ability to burst at 10 fps outperform the Q7's more modest 5 fps frame rate, making the Sony more adept at capturing elusive moving subjects.

Autofocus and Burst Performance: Speed and Accuracy Tested

Focusing performance quickly becomes a make-or-break point in certain photography genres.

Pentax’s Q7 employs contrast-detection autofocus only, with single, selective, and tracking modes available. It lacks phase-detection and animal eye AF, and focusing can feel sluggish, particularly in low contrast or low-light. Continuous AF is absent, which limits usefulness for sports or action photography.

Sony’s NEX-5T benefits from a hybrid autofocus system blending contrast and phase detection across 99 points (25 cross-type). This enables faster, more reliable lock-on and superior tracking for moving subjects. Continuous AF works in live view and during video recording. Burst shooting hits 10 fps (vs. Q7’s 5 fps) - a strong advantage for wildlife and sports enthusiasts.

Build Quality and Environmental Resilience

Both cameras are entry-level craftings without professional-grade weather sealing or ruggedization.

The Q7 feels plasticky but solid given its size, with weather-proofing notably absent. Similarly, the NEX-5T’s plastic construction is durable but not sealed against dust or moisture. Neither is shockproof or freezeproof. For outdoor photography demanding reliability in harsh conditions, neither is ideally suited.

Lens Ecosystem: Freedom Versus Convenience

Arguably the defining lens story differentiates these cameras.

Pentax’s Q mount features a small but specialized lens line of only 8 native lenses, including ultra-compact primes and a few zooms. This limits versatility, yet the small sensor’s crop factor makes shorter focal lengths equivalent to very long reach - beneficial for telephoto needs but limiting for wide or standard perspectives.

Sony’s E mount boasts a vast ecosystem - over 120 lenses from Sony and third parties - spanning ultra-wide to super-telephoto, prime to zoom, and affordable to pro-level. This extensive lineup significantly broadens creative options and future expandability.

Video Capabilities and Limitations

If video matters, consider functionality closely.

The Pentax Q7 supports Full HD (1080p) recording at 30fps in MPEG-4 and H.264 formats. It lacks microphone input and advanced video stabilization - a limiting factor for serious video.

The Sony NEX-5T records Full HD at up to 60fps in AVCHD and MPEG-4, with on-sensor stabilization helping handheld footage look smooth. Although lacking mic and headphone ports, the presence of touchscreen autofocus during video is a plus.

Shot-to-Shot Practicalities: Battery Life and Storage

Long shooting sessions reveal their endurance.

The Pentax Q7 offers roughly 250 shots per charge using the D-LI68 battery, modest but workable. The Sony NEX-5T stretches to approximately 330 shots with its NPFW50 battery - a noteworthy bump for travel and events.

Storage-wise, both use SD cards, but the Sony also supports Sony’s proprietary Memory Stick Pro Duo / Pro-HG Duo cards. Each allows one slot, demanding occasional card swaps for extended shooting.

Connectivity: Wireless and Tethering

Best-in-class portable cameras today incorporate wireless connectivity, but these 2013 models offer limited options.

The Q7 supports Eye-Fi cards for wireless image transfer but no built-in Wi-Fi or Bluetooth.

The NEX-5T includes built-in Wi-Fi and NFC for seamless pairing with smartphones - a significant user experience plus for social sharing or remote shooting.

Price-To-Performance Ratio: What Are You Getting for Your Money?

At launch, the Pentax Q7 priced around $480, the Sony NEX-5T at $400 - Sony comes in cheaper despite offering a larger sensor and more robust feature set.

Over time, prices vary on resale and retail deals but expect Sony to provide more bang for buck in terms of image quality, autofocus, and lens options. Pentax’s proposition centers on ultra-compactness and specific shooting styles favoring telephoto reach.

How These Cameras Score Overall and By Genre
