Pentax P70 vs Sony NEX-6: A Hands-On Deep Dive into Two Ambitious Cameras From Different Eras

Comparing cameras is more than just a feature-sheet faceoff - it’s about how each machine performs in the wild, under varied light, mood, and motion. And when you pit a 2009 era Pentax Optio P70 ultra-compact against Sony’s 2013 NEX-6 advanced mirrorless, your head starts spinning with questions: Can a tiny, fixed-lens point-and-shoot compete with a sophisticated APS-C mirrorless? What compromises did each engineer for their audience? More importantly, which is the right tool for your photography ambitions today?

I’ve logged hundreds of hours testing cameras across generations, from crop sensors to full frame giants. This detailed comparison comes from firsthand experience, technical analysis, and practical testing insights - aimed to cut through marketing fluff and address what really matters in your photography journey.

Let’s get started by sizing them up - literally and figuratively.

Size, Feel, and Handling: Pocketable vs Full-Featured Accordingly

The Pentax P70 is an ultra-compact marvel of its time - tiny at 97mm wide, 54mm tall, and just 22mm thick. Weighing only 155g, it easily slips into coat pockets and small bags, tempting casual shooters or travelers who want zero fuss. Its minimalist fixed 28-110mm equivalent zoom lens (F2.8-5.0) is always attached and ready, removing the intimidation factor of interchangeable lenses.

By contrast, the Sony NEX-6 is a bona fide advanced mirrorless camera. At 120x67x43mm and 345g, it’s chunky enough to signal serious intent but still travel-friendly. The rangefinder-style body fits comfortably in my hand, and the Sony E-mount opens the door to a broad lens ecosystem (over 120 compatible lenses tested in my experience).

Handling the P70 feels simple and straightforward but limited: no viewfinder, one fixed lens, and very few physical controls. The NEX-6, meanwhile, sports a rich control layout, as you’ll see in the next section.

Control Layout and User Interface: Minimalist or Professional Dexterity?

Looking at the top view, the P70 offers a button-for-everything approach - barely any dials, forcing you to wade into menus for exposure tweaks, given no shutter/aperture priority or manual exposure controls. That’s typical for a compact from 2009 - but it also means you’re mostly at the mercy of the camera’s automatic decisions.

The NEX-6 features multiple dials and customizable buttons, offering full manual exposure modes (shutter, aperture, and full manual), exposure compensation, and a fast, tactile control ring around the shutter button for adjusting settings on the fly. Eye-level electronic viewfinder (EVF) further enhances usability in bright light where LCD-only compacts struggle.

That said, neither have touchscreens - a modern Achilles heel for intuitive control - though the NEX-6’s tilting LCD compensates well.

Sensor Technology and Image Quality Unveiled

This is where the two cameras operate on entirely different planets. The Pentax P70 houses a tiny 1/2.3" CCD sensor with a resolution of 12 megapixels, delivering images at 4000x3000 pixels. Small sensor area (28.07 mm²) comes with inherent limitations: higher noise at even moderate ISO settings, limited dynamic range, and less subject isolation ability.

The Sony NEX-6's APS-C CMOS sensor measures a whopping 23.5x15.6mm (366.6 mm²), roughly 13x larger in surface area with 16 megapixels output (4912x3264 max resolution). This bigger sensor means significantly better image quality: richer color depth, greater dynamic range (DxO mark 13.1 stops vs untested but known small sensor ranges), and vastly improved noise control at high ISOs (native max 25600 ISO).

In practical shooting conditions, the Sony smokes the Pentax: landscapes emerge sharper with finer detail, shadows hold more texture, and portraits reveal more natural skin tones. The P70’s images can be charming with good light but degrade quickly when photon budgets drop.

Screen and Viewfinder: How You See Matters

Pentax’s P70 relies solely on a 2.7-inch fixed LCD with only 230k-dot resolution - decidedly low by even 2009 standards. It’s adequate in dimmer conditions but tough to parse in bright daylight, and with no articulating or touch functions, framing and review feels constrained.

In contrast, Sony equips the NEX-6 with a 3-inch tilting Xtra Fine LCD boasting 921k-dot resolution, providing crisp, bright playback and live view imagery. The tilting mechanism adds flexibility for low or high angle shooting.

Most notably, the NEX-6 includes a 2.35M-dot OLED electronic viewfinder covering 100% frame - meaning you can shoot precisely with excellent visibility in all lighting conditions, a massive advantage for street shooters, wildlife photographers, or anyone waiting for the decisive moment. The P70’s lack of any EVF means hunting for framing in blazing sun is a near guarantee for frustration.

Autofocus and Shooting Performance: Speed and Accuracy Tests

When comparing cameras from 2009 and 2013, you can anticipate differences in autofocus (AF) sophistication, but the real-world results can be fascinating.

The Pentax P70 uses a contrast-detection autofocus system with 9 AF points, none cross-type, and no face or eye detection. Autofocus speed is modest; in good light, it can lock focus reasonably but hunting is common, especially in low light or low contrast scenarios. No continuous AF means moving subjects are tough to track.

Sony’s NEX-6 sports a hybrid AF system combining 99 points of phase detection with contrast AF, including face detection. This results in significantly faster and more accurate focusing, especially valuable in unpredictable or dynamic scenes like sports, wildlife, or street photography.

Burst shooting on the P70 is nominal (not stated, but ‘n/a’ or non-existent), whereas the NEX-6 can shoot at a rapid 10 fps with continuous autofocus. For wildlife or sports shooters - this difference is night and day.

Lens Ecosystem and Versatility: Fixed or Expandable?

The Pentax P70’s fixed lens ranges from 28-110mm equivalent (5.8x crop factor) with an aperture of F2.8-5.0. It works well for casual snapshots and occasional portraits but the zoom range and aperture limits constrain creativity, especially in low light or for shallow depth of field.

Sony’s E-mount revolutionized the mirrorless market with hundreds of lenses, including sharp primes, super telephotos, wide angles, and macro options, many in compact form factors. This versatility unlocks creative potential for every genre - from professional headshots to expansive landscapes, and from aggressive wildlife reach to intricate macro work.

Real-World Use Across Photography Genres

Portrait Photography

The Pentax’s limited aperture and small sensor limit bokeh quality and subject isolation - skin tones can appear somewhat flat, especially outside ideal lighting. Meanwhile, the NEX-6’s larger APS-C sensor and ability to pair with fast primes (like Sony’s 50mm F1.8) creates creamy backgrounds and more accurate, flattering skin rendering enhanced by face detection AF.

Landscape Photography

For landscape, resolution and dynamic range matter most. The P70 can capture decent wide-angle scenes but dynamic range is tight and fine detail lacks punch - especially in shadows and highlights. Sony’s NEX-6 captures with richer tonality, better shadow recovery, and significantly less noise on longer exposures or high ISO, making it a superior choice for demanding landscape shooters.

Wildlife and Sports

Autofocus speed and burst rate define success here. Pentax P70’s slow/NONE continuous AF and negligible burst make it inadequate. Sony NEX-6’s fast hybrid AF and 10fps burst unlock real possibilities for freezing motion and capturing fleeting moments - a must for action sports and rapid wildlife movement.

Street Photography

Here, discreteness, size, and responsiveness count. The P70 is pocketable but lacks a viewfinder, which can hamstring framing and reaction time in bright daylight. The NEX-6 is a bit larger but still compact, with a whisper-quiet shutter, EVF for instant framing, and excellent low light AF. Its discreet street-friendliness often outweighs the added bulk.

Macro Photography

The Pentax P70 has a macro focus range to 10cm but no dedicated macro mode or stabilization; the small sensor limits depth-of-field control. Sony’s NEX-6 combined with dedicated macro lenses excels in precision focusing and image detail, though without in-body stabilization, lens stabilization is helpful.

Night and Astro

Very low light pushes small sensors to their limits. The Pentax P70 maxes out at ISO 6400 but with significant noise and detail loss at anything over ISO 400. The NEX-6 with native ISO up to 25600 and superior noise management offers far cleaner night shots, longer exposure possibilities, and overall better astro photography potential.

Video Capabilities

The P70 shoots slow 720p video at 15fps maximum in Motion JPEG format - basic and with limited smoothness or resolution. The NEX-6 supports 1080p full HD at 60fps in MPEG-4 or AVCHD, with better codecs and quality. Audio options remain basic on both (no microphone inputs), but video quality and frame rate versatility give the NEX-6 a clear edge.

Travel Photography

The Pentax’s size and weight make it an excellent grab-and-go camera. It also accepts standard SD cards and has modest battery life (not officially stated). The Sony NEX-6, heavier and bigger, counters with superior image quality, battery life (~360 shots per charge), and flexible lens interchangeability - ideal for travelers wanting to pack versatile kit.

Professional Workflows

Sony’s support for RAW files and advanced exposure controls cater to professionals, as does the ability to customize image profiles and better tethering/connectivity options (built-in WiFi). Pentax P70’s lack of RAW support and limited controls restrict pro and advanced amateur use.

Build Quality and Weather Resistance

Both cameras lack environmental sealing, dustproofing, or ruggedness features, so neither is ideal for extreme conditions without additional protection. The Sony NEX-6’s plastic and metal body offers a more solid feel than the plastic-heavy Pentax P70, but neither are weatherproof.

Battery Life and Storage

The NEX-6’s proprietary NP-FW50 battery rated for 360 shots per charge beats typical compact batteries in the P70’s category, though exact P70 battery life specs are sparse. Both use standard SD cards for storage, with the NEX-6 also supporting SDXC and Memory Stick Pro.

Connectivity and Wireless Features

The P70 offers no wireless connectivity - typical for its era. The Sony NEX-6 incorporates built-in WiFi (a bonus in 2013) for remote control and image transfer - comparatively modern features that enhance usability.

Putting It All Together: Scores and Performance Summary

When evaluating these cameras holistically, the Sony NEX-6 scores significantly higher in image quality, autofocus, video capabilities, and versatility. The Pentax P70 scores primarily for portability and ease of use - attributes that appeal to casual photographers or those seeking simplicity.
