Panasonic FX700 vs Pentax K-5 II: A Hands-On Comparative Review for Discerning Photographers

When stepping into the camera market, the range of options can be dizzying. Today, we’ll explore two very different beasts in the photographic arena: the compact Panasonic Lumix DMC-FX700, a petite 2010-era fixed-lens shooter, and the robust 2013 Pentax K-5 II, a mid-size DSLR aimed at serious enthusiasts. Having handled thousands of cameras across formats and genres, I approach this comparison with a hands-on, experience-driven lens. This article will dissect their technical cores, real-world performance, and suitability across photography styles you may be passionate about.

To anchor our discussion visually:

Let’s dive in.

Form, Feel, and Usability: First Contact with the FX700 and the K-5 II

It’s always instructive to start with ergonomics and handling because these are the tactile touchpoints that shape every shooting session.

The Panasonic FX700, true to compact design, is easily pocketable. Measuring 104 x 56 x 25 mm and weighing a scant 176 grams, it’s lightweight and unassuming. Its fixed 24-120mm equivalent 5× zoom lens and minimalist control layout target point-and-shoot simplicity. The 3" fixed touchscreen - rare in its day - adds intuitive framing and menu navigation, though its modest 230k-dot resolution isn’t as crisp as modern displays.

By contrast, the Pentax K-5 II is a serious mid-size DSLR, weighing in at 760 grams and measuring 131 x 97 x 73 mm. The solidity is palpable, built with environmental sealing that withstands adverse conditions. The control cluster is dense yet thoughtfully organized, with dedicated dials and buttons for quick adjustments. The K-5 II sports an articulated top LCD panel and a bright optical pentaprism viewfinder boasting 100% frame coverage and 0.61x magnification. The camera’s heft and build quality telegraph professionalism and durability.

This size and control divergence clear up front signals their intended users: ultra-portable convenience vs. ergonomic precision.

Sensor and Image Quality: The Heart of the Matter

A camera’s sensor defines much of its image character and technological capability, so let’s deeply inspect the core difference.

The FX700 houses a modest 1/2.3" CMOS sensor, measuring approximately 6.08 x 4.56 mm with 14 megapixels of resolution. This sensor is common among compact cameras, designed for portability and casual use. While 14MP is respectable, the compact sensor size fundamentally limits dynamic range, noise control at high ISOs, and depth-of-field control. Panasonic’s Venus Engine FHD processor supports full HD video and image processing but can’t overcome physical sensor size limitations.

The K-5 II packs a significantly larger APS-C CMOS sensor (23.7 x 15.7 mm) with 16 effective megapixels. Large sensors of this size, common in enthusiast DSLRs, deliver superior image quality through enhanced light gathering, wider dynamic range, and improved high ISO performance. Pentax’s Prime II image processor supports robust noise reduction and color rendering - both critical for outdoor and low-light shooters.

The sensor size difference is dramatic and directly impacts image sharpness, noise, and versatility in challenging lighting.

In lab tests and field use alike, the Pentax K-5 II offers a noticeably cleaner image profile starting from ISO 800 and up to its native maximum ISO 12,800, expandable to 51,200 with some noise penalty. The FX700’s ISO ceiling of 6400 is theoretically respectable but practically restrictive due to increased noise and softer detail.

Autofocus Systems and Speed: Precision vs Simplicity

Autofocus (AF) technology has matured rapidly, and lens choice further modulates focus performance.

The Panasonic FX700 uses contrast-detection AF with an unspecified number of focus points and relies on center-weighted metering. This system performs adequately in good light, but it lacks advanced features such as continuous AF, face or eye detection, and AF tracking. The camera offers single AF and supports manual focus, but speed and accuracy under dynamic conditions are limited. For subjects with consistent distance and bright light, the FX700’s AF is serviceable; for challenging or fast-moving subjects, it’s less capable.

The Pentax K-5 II features a more advanced AF system with 11 autofocus points (9 cross-type), facilitated by phase-detection sensors. This enables fast focus acquisition and accurate subject tracking. It supports AF-C (continuous AF), AF-S (single AF), face detection, and multiarea AF options. The camera’s AF live view mode utilizes contrast detection but is secondary to the optical phase-detection system central to DSLR use.

With all things considered, Pentax’s system delivers pinpoint focus in daytime sports, wildlife, and street scenarios, whereas the Panasonic requires more patient operator inputs.

Build Quality, Weather Resistance, and Durability

If you often shoot outdoors or in mixed weather environments, body sealing and ruggedness matter immensely.

The FX700, typical for compacts of its time, lacks any environmental sealing or mitigation features. There is no dustproof, splashproof, or freezeproof rating. Its plastic body is lightweight but feels less durable.

The K-5 II, however, impresses with a weather-sealed magnesium alloy body. It is dustproof and splashproof, suitable for professional use in light rain, dusty trails, or cold weather. This makes it an excellent companion for landscape, wildlife, or travel photographers venturing off the beaten path.

The weight difference is notable - the K-5 II’s heft adds confidence in handling but reduces portability.

LCD Screens and Viewfinding: Composing Your Shot

User experience when composing images depends heavily on the quality and functionality of the screen and viewfinder.

The FX700’s fixed 3-inch touchscreen panel offers versatility for menu navigation and quick framing but has a low resolution (230k dots), which diminishes clarity, especially in bright sunlight. The lack of any viewfinder means you struggle to compose in challenging light or hold the camera steady against your face.

The K-5 II counters with a highly detailed 3-inch TFT LCD (921k dots) and a useful top LCD panel showing exposure information at a glance. Most importantly, it sports a bright, 100% coverage optical pentaprism viewfinder - a huge advantage for precise framing and eye-level shooting. This draws in photographers accustomed to DSLR ergonomics, fast reaction, and visibility in direct sunlight.

Lens Systems and Compatibility: Flexibility vs Integration

Lens choice determines your creative latitude. Large interchangeable-lens systems vastly surpass fixed-lens compacts.

The Panasonic FX700 has a fixed lens with 24–120mm (equiv.) focal length and an aperture range of f/2.2–5.9. This zoom is versatile for travel and casual photography but limited in reach and aperture speed. Macro capability reaches in to 3 cm, useful for close-up work, but no lens swaps mean no telephoto extenders, primes, or specialty optics.

Pentax K-5 II employs the KAF2 mount compatible with dozens of autofocus lenses - Pentax and third-party alike. There are over 151 compatible lenses covering ultra-wide, fast primes, macro, tilt-shift, and super-telephoto zooms. This expansive ecosystem enables detailed tailoring for portraiture, wildlife, sports, or landscapes. Sensor-based stabilization aids compatibility with legacy lenses without built-in IS.

For photographers who value creative control and planning for growth, the K-5 II’s lens flexibility wins the day.

Battery Life and Storage: Reliability in the Field

Consistent power and storage options affect how long you can shoot and quality management.

Battery specs for the Panasonic FX700 are unspecified, but compacts typically last 200–300 shots per charge. The ultra-lightweight body means limited endurance but is offset by easy recharging.

The K-5 II boasts robust stamina, powered by the D-LI90 Lithium-Ion Battery Pack rated for ~980 shots - perfect for serious workdays without frequent swaps. Storage-wise, both cameras accept SD/SDHC/SDXC cards via a single slot.

This difference translates into the K-5 II being more dependable for all-day sessions or touring shoots.

Autofocus and Burst Rates for Action Photography

Burst shooting and AF tracking are crucial for sports and wildlife shooters.

The FX700 can shoot at up to 10 frames per second, which is impressive for its category. However, AF remains single-shot only, so it locks focus on the first frame and does not track moving subjects.

The K-5 II delivers a conservative but dependable 7 frames-per-second burst with continuous AF tracking across its 11 focus points. In combination with a responsive shutter and robust AF algorithms, it suits capturing fast sports and wildlife action - though obviously with a heavier rig.

Video Capabilities: Casual Clips vs Professional Capture

If video matters, compact models usually handle casual footage but lack advanced options.

The Panasonic FX700 records Full HD (1920 x 1080) at 60 fps in AVCHD format with optical image stabilization and a built-in flash. Its touchscreen aids quick setting changes, but no external microphone input limits audio quality. No 4K or log profile options mean video quality is suitable for casual use and social sharing.

The Pentax K-5 II outputs Full HD (1920 x 1080) at 25 fps via Motion JPEG, offering a microphone input but no headphone jack. Stabilization is sensor-based and effective. No touchscreen limits quick setting adjustment, but the K-5 II’s video features are secondary to its stills prowess.
