Olympus XZ-1 vs Pentax K-5: A Comprehensive Camera Comparison for Every Photographer

Choosing the right camera can be a daunting process, especially when models come from very different categories but appeal to similar audiences. The Olympus XZ-1 and the Pentax K-5 serve quite distinct photographic needs but share a common focus on offering quality and creative control, making their comparison an interesting study in versatility and specialization. Having tested thousands of cameras over the last 15 years, we’ll walk you through key aspects you need to consider based on real-world experience, technical insight, and user-focused evaluation.

Whether you’re a photo enthusiast looking for a capable compact or a professional eyeing a mid-level DSLR with advanced features, this comparison will help you pick the camera that aligns with your creative objectives, budget, and workflow.

Getting to Know These Contenders: An Overview

Before diving deep, here’s a quick snapshot of what you’re looking at:

Both cameras offer manual controls, raw shooting, and image stabilization, yet their design philosophies and photographic appeal differ significantly.

Size, Ergonomics, and Handling: Comfort Meets Control

Your interaction with a camera heavily depends on its physical design. How it feels in your hands, the intuitiveness of control placement, and ergonomics influence your shooting enjoyment and efficiency.

Body and Grip: Compact vs. DSLR

The Olympus XZ-1 is a compact design engineered for portability without sacrificing too much control. Measuring 111x65x42mm and weighing just 275 grams, it fits comfortably in a jacket pocket or small bag.

In contrast, the Pentax K-5 is a traditional mid-size DSLR, sized at 131x97x73mm with a solid grip and weighing 740 grams. It offers a more substantial, tactile feel, designed for longer shoots and more complex setups.

Button Layout and Top Controls

Looking from above, the two cameras diverge in complexity. The XZ-1 opts for a minimalistic approach with fewer dials, which may appeal to casual shooters or travelers.

The K-5 boasts a heritage design with dedicated dials for shutter speed and ISO, a top LCD panel for quick data visibility, and customizable buttons, catering to photographers seeking rapid adjustments in the field.

Recommendation:

• If you value compactness and discreet shooting, the XZ-1’s handiness is unbeatable.
• For tactile control and more manual adjustment options, the K-5’s layout is ideal.

Sensor and Image Quality: The Core of Photographic Excellence

Image quality hinges primarily on sensor size, technology, and processing. Let’s examine how these cameras stack up.

Sensor Size and Technology

The Olympus XZ-1 features a 1/1.63" CCD sensor measuring 8.07 x 5.56 mm (approximately 44.87 mm²). CCD sensors are known for pleasing color rendition but generally offer lower high-ISO performance than modern CMOS sensors.

The Pentax K-5 houses a much larger APS-C CMOS sensor (23.7 x 15.7 mm) spanning 372.09 mm² – over 8 times the surface area. Larger sensors collect more light, provide improved dynamic range, and produce cleaner images especially in low light.

Resolution and Output Size

• The XZ-1 outputs 10 megapixels (3664 x 2752 pixels), enough for prints up to A3 size and web sharing.
• The K-5 doubles the resolution at 16 megapixels (4928 x 3264 pixels), offering greater cropping flexibility and larger print potential.

Image Quality Metrics (Based on DxOMark Testing)

The clear winner in sensor performance is the Pentax K-5, delivering sharper, cleaner, and more nuanced images especially in challenging light and high dynamic range scenes.

LCD Screen and Viewfinder: Composing with Confidence

Seeing your composition clearly is fundamental. Both cameras feature 3" fixed LCDs, but with critical differences.

• Olympus XZ-1 offers an OLED panel at 614k dots, delivering vivid colors and excellent contrast. However, it lacks touch capabilities and the screen resolution is modest by today’s standards.

• Pentax K-5 uses a brighter TFT LCD at 921k dots, with a reliable display even under direct sunlight. The K-5 also includes a high-quality optical pentaprism viewfinder covering 100% of the frame with 0.61x magnification, enabling precise manual focusing and framing.

The Olympus has no built-in viewfinder, though an optional electronic unit is available externally. If you’re used to composing with an eye to the viewfinder, the K-5’s experience will be notably superior.

Autofocus and Shooting Speed: Catching the Perfect Moment

Focusing speed and accuracy define how smoothly your creative ideas translate into images.

• The XZ-1 has an 11-point contrast-detection AF system with face detection. It supports single-shot autofocus, tracking, and live view focusing, but continuous AF and rapid tracking are limited. The burst rate is a modest 2 frames per second.

• The K-5 features an 11-point autofocus system with 9 cross-type sensors and both phase-detection plus contrast detection. It supports face detection, continuous AF, selective AF point selection, and advanced tracking modes ideal for moving subjects. Burst shooting reaches up to 7 fps, suitable for wildlife and sports.

Real-World Testing Insights:
In controlled shooting tests, the K-5’s AF locks faster in low light and tracks subjects more reliably. The XZ-1, while competent in daylight portraiture and casual scenes, may struggle with fast action or wildlife.

Lens Ecosystem and Flexibility: Exploring Creative Boundaries

The Olympus XZ-1 has a fixed lens with a versatile 28-112mm (equivalent) focal range and a wide maximum aperture of f/1.8-2.5. This fast lens excels in low light and portraiture, providing attractive background blur and handy macro focus as close as 1 cm.

Pentax K-5 opens up an entire expansive lens ecosystem with Pentax KAF2 mount compatibility. You have access to over 150 lenses, from ultra-wide, telephoto zooms, tilt-shift lenses to high-performance primes and macro optics.

Macro and Close-Up:

• Olympus offers a near-microscopic 1 cm focus for detailed macros in a pocketable setup;
• Pentax users can select dedicated macro lenses with higher magnification and exceptional optical quality.

Recommendation:

• Choose Olympus XZ-1 if you want a fast, versatile all-in-one solution with ready-to-go optics.
• Choose Pentax K-5 if you prefer growth potential with lenses tailored to every photographic genre.

Build Quality and Weather Sealing: Shooting Anywhere, Anytime

The Pentax K-5 shines in ruggedness with environmental sealing that protects against dust and moisture, enabling outdoor photographers to shoot in adverse weather. It is built with magnesium alloy, emphasizing durability.

The Olympus XZ-1, by contrast, lacks weather sealing and protective ruggedness. Its compact form factor comes at the price of environmental resilience.

Battery Life and Storage Considerations

Battery endurance can define your capacity to shoot throughout the day.

• The K-5 uses the D-LI90 battery, rated for approximately 980 shots per charge - excellent for day trips and extended photo sessions.

• The XZ-1 uses a smaller Li-50B pack, rated for around 320 shots, which will require bringing spares for longer outings.

Both cameras use single SD/SDHC/SDXC storage slots, simplifying media management but limiting redundancy options.

Video Capability: Bringing Motion to Life

If video is part of your creative mix:

• The Olympus XZ-1 records HD video at 1280x720p at 30fps in Motion JPEG format without external mic input.

• The Pentax K-5 steps it up with full HD 1920x1080p at 25fps, supports 720p at 25 or 30fps, and offers a microphone input for improved sound capture.

While neither camera targets heavy video work, the K-5 is the better pick for those wanting casual videography with more control.

Specialized Photography Genres: Who Shines Where?
