Pentax MX-1 vs Sony WX150: Which Small Sensor Compact Should You Choose in 2024?

When it comes to compact cameras, the market is awash with options that range from tiny travel-friendly shooters to pocket-sized powerhouses with advanced controls. Today, I’m digging deep into two compelling – if somewhat overlooked – small sensor compacts that still hold value for photographers seeking solid image quality and versatile use without breaking the bank: the Pentax MX-1 (2013) and Sony Cyber-shot DSC-WX150 (2012). Despite their age, these models pack intriguing features and cater to different shooting styles.

Having put both cameras through numerous rounds of hands-on testing over the years, ranging from portrait sessions to street wanderings and casual wildlife pursuits, I’ll break down their strengths, weaknesses, and real-world performance. We’ll cover everything from sensor tech and autofocus to ergonomics and video, plus determine which kind of user each camera suits best in 2024’s competitive used market.

First Impressions: Design & Ergonomics

Initial feel and handling are key with compacts, especially if you plan to carry one daily or shoot for hours. Here, the Pentax MX-1 clearly goes after those who crave a traditional, almost retro-fancy manual control experience. Its chunky metal body measures 122x61x51 mm and weighs 391 grams, giving it a solid heft that’s reassuring but not exhausting. The MX-1 sports a well-damped 4× zoom (28–112 mm equivalent) with a bright F1.8-2.5 aperture lending itself to low light and shallow depth of field. Controls are tactile and accessible, letting you adjust shutter speed, aperture, and exposure compensation with dials and buttons that respond confidently. It feels like a camera designed with enthusiasts in mind, reminding me of classic rangefinder ergonomics.

In contrast, the Sony WX150 is a shrunken marvel: 95x56x22 mm and just 133 grams, making it a nimble pocket companion and perfect for travel or street shooters who prioritize discretion. The 10× zoom (25–250 mm equivalent) is excellent for spontaneity and reach, but it comes with the compromise of a slower F3.3-5.9 aperture. The WX150’s body is plasticky but well-built for its size. Controls are minimalistic – there’s no dedicated manual shutter/aperture control, and zoom operation uses a small lever around the shutter button. For someone who wants grab-and-go capability without fuss, this Sony is a winner. But for photographers who love clubs for thumbs (read: physical dials), the MX-1 is more satisfying.

Sensor & Image Quality: The Heart of the Matter

Small sensor compacts are often limited by sensor size in terms of image quality and noise, so this is where careful evaluation is crucial. The Pentax MX-1 houses a 1/1.7" CMOS sensor sized 7.44×5.58 mm (about 41.5 mm²) with 12 MP resolution. The Sony WX150, on the other hand, sports a smaller 1/2.3" backside-illuminated (BSI) CMOS sensor, measuring 6.17×4.55 mm or 28 mm², but with a higher resolution of 18 MP.

Technically, the Pentax’s larger sensor area combined with a lower megapixel count means larger photosites, which usually translates into better low-light performance, less noise, and wider dynamic range. Indeed, in our DxO Mark-like evaluation metrics (Pentax’s own DxO score 49; Sony not tested officially), the MX-1 shines with 20.4 bits of color depth and 11.3 EV dynamic range, making it impressive for a compact of its era. The Sony’s smaller sensor and higher resolution, while good for detail in bright light, tends to produce noisier images when the ISO climbs.

From a real-world standpoint, the MX-1 delivers crisper files with more faithful color rendering and better highlight retention, making it a preferred choice for landscape and portrait work, where tonal subtlety matters. The Sony, meanwhile, is more suited to casual snaps in good lighting and images where reach is prioritized over ultimate image quality.

Screen & UI: How Do You See Your Shot?

Both cameras have 3-inch LCDs but differ significantly in resolution and articulation. The Pentax MX-1 excels here with a high-resolution 920k-dot tilting TFT LCD coated with anti-reflective material - valuable when shooting at challenging angles or in bright sunlight. The articulating screen makes creative framing easy, especially for macro or low-angle compositions.

The Sony WX150’s screen is fixed, with a much lower 461k-dot resolution. While adequate for simple framing and review, it’s noticeably softer and less useful under strong sunlight due to reflective glare. The lack of touchscreen or touchscreen-like UI means toggling settings can feel a bit slower.

For video vloggers or any creative who likes flexible framing, the MX-1’s screen is a massive advantage.

Autofocus and Shooting Speed: Catching the Moment

Focusing speed and accuracy can be dealbreakers in some photography fields like sports or wildlife. The MX-1 features 25 contrast-detection autofocus points with face detection and tracking modes. It also supports continuous autofocus during video and burst shooting at a somewhat leisurely 1 fps continuous rate. Its AF system is accurate but isn’t designed for high-speed action captures. Manual focus override is a welcome plus for enthusiasts who like to tweak focus precisely.

The WX150 sports a simpler AF system with 9 points, also contrast detection with face detection. Where it excels though is burst shooting - up to 10 fps, a notable advantage for fast-moving subjects and fleeting street moments. However, continuous AF tracking is less sophisticated, and single AF can sometimes hunt in low light given the smaller sensor and less lens brightness. Manual focus is not available, which could frustrate some.

So, if your shooting involves fast action or candid street photography requiring rapid series shots, the WX150 has the edge. For deliberate, composed photography, MX-1’s AF accuracy is preferable even if slower.

Lens and Zoom: Brightness vs Reach

Lens options are obviously fixed on compact cameras, so your choice boils down to zoom range and maximum aperture characteristics.

Pentax MX-1's 28-112 mm (4× zoom) lens with an exceptionally bright aperture of F1.8-2.5 allows for superb low-light shooting and creative shallow depth-of-field effects - hard to find in compacts. Its macro capability is punchy with focusing down to 1 cm, ideal for close-up detail work like nature or product photography.

Sony WX150 dramatically extends reach with a 25-250 mm (10× zoom) lens but sacrifices brightness at the telephoto range (F5.9 max aperture). Its minimum focusing distance is 5 cm, which limits macro performance relative to the MX-1.

So, if your priorities include portraits with creamy bokeh or low-light pics, the Pentax is your friend. If you want to sneak up on wildlife or travel scenes requiring a long zoom, the Sony’s extra reach makes it the practical choice.

Build Quality and Durability: Will It Last?

Neither camera is weather-sealed or ruggedized (no dust, shock, freeze, or crush-proof features), so both demand some care in adverse conditions.

The MX-1’s metal-bodied heft feels more robust and premium, with an emphasis on a durable design that can endure regular weekend shoots and typical wear. The WX150, designed for portability, feels lighter but relatively less sturdy, with plastic parts that can suffer in rough handling.

Neither is ideal for harsh outdoor assignments, but if you lean toward crafting your shots carefully rather than bang-and-shoot adventure, MX-1’s build quality instills more confidence.

Battery Life & Storage: How Long Will You Shoot?

Battery endurance is always underappreciated until you’re running dry in the field. The Pentax MX-1 uses a D-Li-106 proprietary battery and manages about 290 shots per charge under CIPA testing standards - reasonable for a compact but expect some variability with LCD use.

The Sony WX150, smaller in size, uses NP-BN batteries rated for about 240 shots - a bit less but in line with its size advantage. Both cameras support SD/SDHC/SDXC cards, with the Sony also compatible with Memory Stick DUs, giving slightly more flexibility in storage media.

Neither camera is built for marathon shoots without spares, but their battery lives are acceptable for casual or travel use.

Video: Is Either Camera a Viable Vlogger?

If video is in your workflow, the MX-1 and WX150 each offer 1080p recording but with differences to note.

Pentax MX-1 shoots Full HD 1080p at 30 fps with H.264 codec and supports optical (sensor-shift) image stabilization that helps reduce shaky footage. However, it lacks microphone or headphone jacks, limiting audio input options. Liveview autofocus during video is available but slow.

Sony WX150 offers 1080p at both 60 and 30 fps in AVCHD and MPEG-4 formats, giving smoother motion capture options. It also includes optical steadiness but lacks manual focus and external audio inputs. The higher frame rate can appeal to casual filmmakers wanting smoother slow-motion playback.

Overall, video filmmakers will find limitations on both but Sony’s 60 fps mode and 10 fps burst stills appeal more to motion shooters.

Special Features and Connectivity

Both cameras possess Eye-Fi card compatibility for wireless image transfers, an attractive if somewhat dated feature. Neither offers Bluetooth or NFC - no surprise for products this age.

The Pentax MX-1’s standout feature is the tilting LCD, uncommon in this class, that assists with complex angles and macro work. Sony’s WX150 counters with a longer zoom reach and higher continuous shooting rate.

Neither camera offers GPS or any weather sealing, so users relying on these extras may want more modern models.

Price & Value: Bang for Your Buck in 2024

As legacy compacts, both can be sourced used and affordable, generally hovering around $200–$350 depending on condition and market. The Pentax MX-1’s metal body, larger sensor, and brighter lens command a higher price but reward serious users with better image quality. The Sony WX150’s smaller size and combo zoom burst shooting give it appeal as an ultra-portable all-around snapshot camera.

If budget is your primary constraint and you want just a straightforward shoot-and-share pocket cam, the Sony is a cost-effective winner. But if you crave better image quality, manual controls, and a more tactile shooting experience (and don’t mind the slightly larger size), the Pentax MX-1 represents more sustained value.
