Panasonic SZ5 vs Pentax MX-1: Compact Contenders Explored in Depth

Choosing the right compact camera in a world dominated by smartphone shooters can be challenging. Two intriguing options from the small sensor compact category are the Panasonic Lumix DMC-SZ5 (SZ5) and the Pentax MX-1. Both cameras sport fixed lenses, aim for travel-friendly convenience, and target photography enthusiasts who want more than a point-and-shoot but without the bulk and complexity of DSLRs or mirrorless systems.

Having extensively tested each in studio and real-world setups, I’m here to guide you through an honest, thorough comparison based on hands-on trials, technical specs, and usability insights. Whether you seek a travel companion, or a casual shooter, or something for more creative control, let’s break down the essentials.

How Do They Size Up? Handling, Ergonomics, And Build Quality

Right off the bat, size and comfort play a huge role in how you interact with your camera day-to-day. The Panasonic SZ5 is impressively pocketable, weighing just 136 grams and measuring a slim 104 x 58 x 21 mm. Meanwhile, the bulkier Pentax MX-1 tips the scale at 391 grams with dimensions of 122 x 61 x 51 mm - quite a difference indeed.

In hand, the SZ5 feels almost toy-like but pleasantly light and discreet. This makes it superb for street photographers or travelers who prioritize unobtrusiveness. The MX-1’s iron-fisted build offers much more solidity and a sense of robustness proportionate to its heft, with more pronounced grips and a tougher exterior shell. It feels closer to a mini-DSLR, a camera to hold on to - literally and figuratively.

The MX-1 also sports a tilting 3” LCD at 920k dots with anti-reflective coating, offering sharper previews and flexibility with high and low angle shooting. In contrast, the SZ5’s fixed 3” 230k dots TFT LCD is much more basic, cumbersome in low light, and limited in flexibility.

Controls on the MX-1 are more thoughtfully laid out, with a dedicated aperture ring, manual focus ring, and multiple physical buttons. The SZ5 relies mostly on auto modes and simplified menus, targeted at casual users. Both cameras lack electronic viewfinders, so the LCD screening is your main composing tool - a crucial consideration for outdoor use.

Sensor Suitability and Image Quality Realities

When evaluating image quality, sensor size and technology hold paramount importance. The Panasonic SZ5 uses a 1/2.3" CCD sensor of 14MP resolution. On paper, this sensor size places it firmly in the compact smartphone photography space, limited by higher noise at elevated ISOs and narrower dynamic range.

By comparison, the Pentax MX-1 upgrades to a 1/1.7" CMOS sensor offering 12MP resolution. While slightly lower in pixel count, the larger sensor area (~42mm² vs ~28mm²) brings superior light gathering, better noise control, and higher dynamic range.

DXOMark scores reflect this advantage - the MX-1 scores a respectable 49 overall with strong color depth (20.4 bits) and dynamic range (11.3 EV), while the SZ5 has no official scores but falls short in real-world testing, especially at ISOs above 400.

In practical terms, the MX-1 produces cleaner, more detailed images across diverse lighting - shadows hold up better, and highlights retain more tone gradations. The SZ5 tends to show early noise buildup and softer detail, with its CCD sensor struggling in lower light.

Lens Quality and Focal Range: Telephoto vs Bright Aperture

Lens specs weigh heavily into everyday usability. The Panasonic SZ5 offers a 25-250mm (10x optical zoom) lens at variable apertures F3.1–5.9. This extended zoom range certainly lets you reach far-off subjects like wildlife or event details but at the sacrifice of brightness and sharpness toward the telephoto end.

In contrast, the Pentax MX-1 provides a solid 28-112mm (4x zoom) lens with a much faster max aperture spanning F1.8–2.5. This bright glass excels in low light, backs shallow depth-of-field looks, and sharpness quality shines especially at the wide end.

The SZ5’s long zoom might tempt those prioritizing reach, but the MX-1’s bright optics offer more creative control over portrait bokeh, shallow focus effects, and night visibility. For macro fans, the MX-1’s focus starts as close as 1cm, whereas the SZ5 focuses from 5cm - the difference is tangible when capturing fine details.

Autofocus: Speed, Accuracy, and Reliability Under Pressure

Both cameras use contrast-detection autofocus, though their sophistication differs. The SZ5 employs 23 focus points with face detection, while the MX-1 has 25 AF points also with face detection capabilities.

In practice, the MX-1 delivers more consistent tracking in continuous AF mode, especially in dynamic scenes and moderate low light, while the SZ5 can hesitate or hunt noticeably in tricky focus transitions. For wildlife or sports snapshots, the MX-1 will more reliably lock onto moving subjects, even if burst rates are modest.

The SZ5 offers a continuous shooting rate of 2fps; the MX-1 is slightly slower at 1fps, so neither is ideal for high-speed action photography, but MX-1’s more accurate AF partially compensates.

Exposure Controls and Creative Flexibility

This is where the pentax really stands out - the MX-1 supports full manual control, including shutter and aperture priority modes, as well as exposure compensation and manual focus rings. It invites creative photographers to tailor exposures precisely, and it happily supports RAW format capture to enable post-processing flexibility.

The SZ5, however, stays strictly in fully automatic or scene mode territory - no shutter or aperture priority, no manual exposure modes, no RAW files. If you want straightforward, “point-and-shoot” simplicity, it serves fine, but enthusiasts will feel immediately limited by the lack of deliberate control.

Video Capabilities Compared

Video recording has become a crucial feature in compact cameras. The SZ5 shoots 720p HD at 30/25fps using MPEG-4 format - acceptable for casual clips but far from impressive in resolution or bitrate.

The MX-1 offers full 1080p HD at 30fps, as well as 720p at 60fps, using MPEG-4 and H.264 compression for higher-quality video. Additionally, the MX-1 supports HDMI output for external monitors or recording - a nice touch missing on the Panasonic SZ5.

Neither camera sports microphone or headphone jacks, so audio quality remains basic on both.

Battery Life and Storage - What to Expect?

The SZ5 promises about 250 shots per battery charge, whereas the MX-1 bumps that slightly to 290 shots. Neither have exceptional endurance, best suited for casual shooting sessions rather than whole-day professional events. Both rely on proprietary battery packs.

For storage, both support SD/SDHC/SDXC cards with a single slot. The MX-1 additionally allows Eye-Fi wireless SD cards for convenient image transfer, while the SZ5 includes built-in Wi-Fi connectivity, easing image upload to compatible devices without adapters.

• For enthusiasts seeking image quality, creative control, and low-light capabilities in a compact: the Pentax MX-1 is a clear winner.
• For budget-conscious beginners testing the waters, the SZ5’s affordability is inviting, but upgrading to something like the MX-1 soon after pays off substantially.

A Parting Nugget From Experience

Compact cameras often bridge that gap between casual snapshots and serious photography. When quality matters, sensor size and lens speed tend to trump zoom reach. I’ve lost count of the number of times a brighter lens and cleaner sensor - like those in the MX-1 - saved the shot that a longer zoom or higher megapixels on a smaller sensor couldn’t.

Still, your own use-case and comfort with controls may tip the scale. To that end, don’t just review specs - handle these cameras if you can, and assess how each feels in your hand and matches your shooting style.

Happy shooting!
