Pentax MX-1 vs Sony NEX-5T

Pentax MX-1 vs Sony NEX-5T: A Thorough Hands-On Comparison for the 2013 Compact vs Mirrorless Battle

In the rapidly evolving landscape of 2013, compact cameras faced a dynamic challenge from relatively new mirrorless models that promised DSLR-level image quality packed into smaller bodies. Two iconic representatives of these categories are the Pentax MX-1, a high-end compact with a bright fixed zoom lens, and the Sony Alpha NEX-5T, a mirrorless system camera boasting APS-C sensor benefits and interchangeable lenses.

Having spent countless hours snapping portraits, landscapes, sports, and more through their viewfinders, I want to share my exhaustive side-by-side evaluation of these two cameras. We’ll focus not on press releases but real-world usage - assessing image quality, handling, autofocus, video, and more - so you can see which might be a better fit for your photographic style and demands.

First Impressions and Build Quality: Compact Classic vs Modern Mirrorless

Starting with the form factor, the Pentax MX-1 feels substantial and robust for a compact but understandably chunky given its larger lens assembly and sensor stabilization mechanism. Its all-metal build yields a satisfying heft that conveys durability without awkward bulk. Pentax opted for a “classic” styling that will appeal to enthusiasts fond of retro-inspired ergonomics: prominent rings and knobs give manual control lovers an immediate sense of familiarity.

By contrast, the Sony NEX-5T flaunts a sleeker, more streamlined silhouette characteristic of rangefinder-style mirrorless cameras. It’s significantly lighter at 276 grams and measures noticeably thinner, making it quite pocketable if you don’t mind carrying an extra lens or two in your bag. The NEX is designed as a flexible system: with an E-mount allowing over 120 available lenses, it invites photographers to grow their setup over time.

Ergonomically, the MX-1's physical controls deliver traditional aperture and shutter dials that reward tactile feedback. The NEX-5T, meanwhile, balances physical buttons with a touchscreen interface, which some purists might find less immediate but beginners could welcome for accessibility.

Both cameras lack weather sealing, so neither is built for rugged abuse, though the MX-1’s thicker body and metal chassis feel a bit better protected against incidental knocks.

Sensor and Image Quality: The Heart of the Matter

Let’s get to what truly distinguishes these bodies - their sensors.

The Pentax MX-1 uses a 1/1.7-inch sensor measuring 7.44 x 5.58 mm with an effective resolution of 12 megapixels. Admittedly, this sensor size and pixel count were standard for premium compacts at the time but pale when stacked against the APS-C sensor inside the Sony NEX-5T, which boasts a whopping 23.4 x 15.6 mm imaging area and 16 megapixels.

In practice, the NEX’s larger sensor delivers genuinely superior image quality - higher dynamic range, richer color depth, and cleaner high ISO performance. Lab tests and in-field trials echo this: the Sony clocks a DXO overall score of 78 compared to the Pentax’s modest 49. That gap translates to more detail retention in shadows and highlights, better noise control in dim scenarios, and better general flexibility for challenging lighting.

The MX-1’s lens - a bright 28-112mm equivalent zoom at f/1.8-2.5 - compensates somewhat by allowing more light capture, which can produce punchy images and attractive shallow depth of field in certain focal lengths. Yet shallow DOF is inherently limited by the small sensor’s physics, so true creamy bokeh and subject isolation is a bit tougher to achieve than on the Sony.

For pixel-peepers or those intending to do serious printwork beyond 8x10 inches, the NEX’s higher native resolution and sensor prowess are an edge you’ll appreciate.

Autofocus and Speed: Catching the Moment

While raw image quality is crucial, a photographer’s ability to track and shoot quickly is equally vital.

The Pentax MX-1 employs a contrast-detection autofocus system with 25 focus points but no phase detection, limiting speed and accuracy, particularly in low light or for fast-moving subjects. Continuous shooting rate is painfully slow at 1 fps - the MX-1 is designed more for contemplative shooting than action.

Sony’s NEX-5T, by contrast, uses a hybrid AF system combining both phase and contrast detection, sampling data from 99 focus points (25 cross-type). This system excels in locking focus quickly and tracking moving subjects effectively. Burst shooting at 10 fps is a substantial advantage for wildlife and sports photography - ideal for sequences where timing is critical.

For photographers shooting street, sports, or wildlife, the NEX holds a clear performance edge, while the MX-1’s AF feels more suited to relaxed, deliberate compositions.

Handling and User Interface: Navigating the Controls

Shooting ergonomics are personal but here’s how these two shape up through my testing:

The MX-1's dedicated dials for aperture and shutter speed enable photographers accustomed to manual modes to work with confidence and speed. The tilting 3-inch LCD with 920k dots is bright and clear though non-touch. At 391 grams it’s on the heavier side for a compact, yet feels secure.

Meanwhile, the NEX-5T’s 3-inch tilting touchscreen (922k dots) offers more flexible composition angles and intuitive menu navigation. The touchscreen adds convenience for setting focus points or changing settings quickly but some users may find it less tactile than traditional wheels. The NEX tips the scales lighter at 276 grams, which combined with its sleek body makes it more pocketable and travel-friendly.

Both lack built-in viewfinders, though the NEX offers an optional electronic viewfinder - a nice add-on for bright light shooting or those who prefer eye-level framing.

Lens Ecosystem and Versatility: Fixed vs Future-Proofed

This is where the comparison polarizes most strongly:

The Pentax MX-1 has a fixed zoom lens offering a modest 28-112mm equivalent range with a bright f/1.8 to 2.5 aperture. This is excellent for low light and portraits but limits versatility for other genres like wildlife or extensive landscapes.

Sony’s NEX-5T, with its E-mount system, opens up a world of lens options - from ultra-wide primes to heavy telephotos, macro lenses, and speciality glass. At launch, over 120 lenses were compatible - a staggering range for an “entry-level” mirrorless camera. Need longer reach or faster glass? Just swap lenses.

This inherent flexibility makes the NEX-5T a more future-proof choice. It can start as a fast travel camera then evolve into a serious tool for diverse shooting disciplines simply by changing glass.

Portrait Photography: Skin Tones and Bokeh Showdown

Portraits highlight the strengths and weaknesses of sensor size and lens character:

The MX-1 is capable of pleasing portraits, particularly when pinning focus on eyes using its 25-point AF and face detection. The bright fixed lens helps separate subject from background at shorter zoom settings but the small sensor restricts the creaminess of bokeh. Skin tones render natural but can sometimes lack subtle gradation in highlight and shadow transitions.

The NEX-5T outperforms here with larger sensor physics enabling smoother bokeh and more three-dimensional subject separation. Portraits show greater nuance in skin textures and tonal range. The added control over aperture using interchangeable lenses means you can choose ultra-fast primes with crazy wide apertures (~f/1.8 or wider).

If you shoot portraits semi-professionally or desire that “portrait-prime” look, the Sony is a clear winner.

Landscape Photography: Dynamic Range and Resolution Power

For landscapes, resolution and dynamic range dictate how much detail and tonal subtleties you can capture in skies and foliage.

Again, the bigger APS-C sensor in the NEX coupled with higher DXO dynamic range (13 stops) trumps the MX-1’s smaller sensor (11.3 stops). Landscape shots from the NEX preserve highlight detail in bright skies and recover shadow areas in underbrush with less noise.

The Sony's higher resolution (16MP vs 12MP) means landscapes hold up better for large prints or cropping. Although the MX-1’s zoom covers moderate wide angles, it lacks ultra-wide capabilities without adapters.

Neither camera is weather sealed, so I wouldn’t risk either in harsh conditions, but the NEX’s lens options include rugged weather-resistant primes.

Wildlife and Sports: Autofocus and Burst Shooting in Action

Here the Sony really asserts its supremacy. The NEX-5T’s rapid 10 fps burst rate and sophisticated hybrid AF with 99 focus points allow fast, accurate tracking of erratic subjects.

The MX-1’s 1 fps continuous shooting along with a contrast-only AF system feels sluggish, making it frustrating for action or wildlife where speed is non-negotiable.

In wildlife photos of birds mid-flight or fast-moving mammals, the Sony’s system is able to capture sharp frames more consistently.

Street Photography: Discreteness and Portability

Street photographers often prioritize compact size, quiet operation, and responsiveness.

The MX-1’s larger body means more presence but the fixed lens keeps it simple and walk-around ready. Its sensor-shift stabilization is handy for handheld shooting in dim conditions where a flash would be inappropriate.

The Sony NEX-5T’s compactness and lighter weight make it more discreet, especially paired with primes. Touchscreen AF selection for quick focus shifts adds responsiveness. However, the lack of a built-in viewfinder might be a drawback in bright sunlight. The optional EVF helps but increases bulk.

Ultimately, the Sony feels like the better street shooter if you value size and AF speed, with the MX-1 as a solid secondary camera.

Macro Photography: Focus Close and Personal

The Pentax impresses with a very close macro focus range of just 1cm, allowing for intimate close-ups with its fixed lens. Sensor-shift stabilization further aids in sharpness at close distances.

The Sony NEX-5T does not have a designated macro lens included but can work with dedicated E-mount macro lenses for superior magnification and shallow depth effects.

If macro shooting is a priority on a budget, the MX-1 is an attractive option. For more advanced macro work, the NEX system’s lens choices win out.

Night and Astrophotography: Handling High ISO Performance

Here sensor size and noise handling dominate.

The Sony’s APS-C sensor offers significantly better low-light performance and cleaner ISO up to 25600 native vs the MX-1’s 12800 max ISO and much noise at higher values.

Long exposures are supported well by both, but the Sony’s higher dynamic range and lower noise floors grant cleaner star fields and night scenes. The MX-1’s slower lens on long zoom settings means less light gathering than the wide aperture end.

Video Capabilities: Recording Quality and Usability

Video aficionados will find the NEX-5T more versatile: full HD 1080p at up to 60fps with AVCHD and MPEG4 codecs allow for smooth, high-quality clips. The camera also features touchscreen focus during recording, making it easier to rack focus.

Pentax MX-1 shoots Full HD 1080p at 30fps with MPEG-4/H.264 but lacks higher frame rates, and video controls are more basic without touchscreen support. The MX-1 includes internal stabilization which helps reduce shake in handheld footage - a boon for run-and-gun videos.

Neither model offers microphone or headphone jacks, limiting audio recording control. However, the NEX supports external flashes giving it an edge for hybrid photography and video lighting setups.

Travel Photography: All-Day Carry and Battery Life

Both cameras offer roughly similar battery performance - approximately 290 shots per charge on the MX-1 and slightly better 330 shots on the NEX-5T. Given the NEX’s lighter body and greater flexibility, it’s likely the better travel companion.

The MX-1’s fixed lens and robust controls mean you’ll spend less time switching settings but also less scope resolution-wise. The Sony’s lens ecosystem can outfit you for any shooting scenario on the road from wide vistas to street candids to portraits.

Professional Use and Workflow Integration

Pro users require reliable RAW file support, tethering capabilities, and robust file handling. Both cameras shoot RAW - the Pentax offering 12MP PEF/ DNG files, the Sony 16MP ARW format - integrating well with Lightroom and Capture One.

The Sony’s greater resolution and dynamic range make it preferred for commercial work or editorial output. Its built-in Wi-Fi (along with NFC) aids rapid file transfer, though pros may find the lack of weather sealing limiting.

The Pentax MX-1 is best viewed as a high-quality enthusiast compact offering solid JPEGs and RAWs for casual professional use or as a versatile backup.

Connectivity and Storage Options

The Sony NEX-5T includes built-in Wi-Fi with NFC for smooth wireless sharing and remote control, a feature missing from the MX-1 which only supports Eye-Fi card connectivity - more limited and rare in use today.

Both cameras use SD card slots, but the Sony NEX adds Memory Stick Pro Duo compatibility for greater media options.

Price-to-Performance Breakdown

Both cameras launched retail around $400, a tempting price point for enthusiasts seeking strong value.

Originally, the MX-1 appeared as a premium compact with standout optical design and analog controls, targeting users upgrading from smartphones.

The NEX-5T’s mirrorless approach offered DSLR-like image quality and flexibility in a similar budget frame - making it a more future-safe investment for photographers poised to expand their kit.
