Panasonic Lumix TS5 vs Pentax K-5 II - Which Camera is Best for You?

Choosing the right camera can be daunting given the variety of models catering to different photography needs. Today, I’m delving into a detailed comparison of two very different cameras: the Panasonic Lumix DMC-TS5 (TS5) - a rugged, waterproof compact - and the Pentax K-5 II, a robust mid-size DSLR aimed at advanced enthusiasts. Both announced in mid-2013, these cameras serve quite distinct audiences, yet each offers compelling strengths. Drawing from extensive hands-on testing across photographic disciplines, I’ll help you understand where each shines and which might be the smarter investment based on your style and priorities.

First Impressions: Design, Build & Ergonomics

Before diving into specs, the look and feel set the tone for the camera’s best use cases.

Panasonic Lumix TS5 – Compact Durability

The TS5 is a compact, rugged waterproof camera designed for adventurous photographers or casual users who want a tough camera without bulk. Its 110 x 67 x 29 mm body is remarkably pocketable and surprisingly lightweight at 214 grams.

The fixed lens 28-128mm equivalent zoom (4.6x optical) combined with its splash/dust/freezeproof construction means you don’t have to baby this camera. I took the TS5 snorkeling and out on hikes where weather was unpredictable - its robustness gives real peace of mind.

Ergonomically, the TS5’s grip is minimal but the button layout is straightforward - though not highly customizable. The non-touch 3-inch TFT LCD screen offers average resolution (460k dots), enough for framing but less detailed for reviewing images.

Pentax K-5 II – DSLR Precision

The K-5 II carries the heft and presence of an advanced DSLR - measuring 131 x 97 x 73 mm and weighing a solid 760 grams with battery. The larger size affords a deep, comfortable grip with plenty of physical controls.

I appreciated the mechanical pentaprism optical viewfinder, which provides a clear, bright 100% coverage view - crucial for manual framing accuracy in varied light. The rear 3-inch fixed TFT LCD features higher resolution (921k dots), double that of the TS5, beneficial when checking image details or navigating menus. This DSLR also has a top LCD for quick settings checks.

Weather sealing is enhanced on this body - dust and splash resistant but not fully waterproof. The build quality feels more professional-grade, ready to withstand heavy use over time.

Sensor & Image Quality: Size Matters

Sensor technology plays a central role in image quality, dynamic range, and ISO performance.

Panasonic TS5 Sensor

• Sensor Type/Size: 1/2.3″ CMOS (6.08 x 4.56 mm)
• Resolution: 16 MP (4608 x 3456)
• ISO Range: 100–6400 native
• Anti-alias filter: Yes

The small sensor size restricts light-gathering capability, especially in lower light. This limits dynamic range and introduces more image noise at higher ISO settings. For casual daylight shooting, the sensor produces decent sharpness and color, but in shadows, the detail drops quickly. The fixed lens and AA filter also dampen micro-contrast.

Pentax K-5 II Sensor

• Sensor Type/Size: APS-C CMOS (23.7 x 15.7 mm)
• Resolution: 16 MP (4928 x 3264)
• ISO Range: 100–12800 native, expandable to 51200
• Anti-alias filter: Yes

The APS-C sensor is roughly 14x larger in surface area than the TS5’s, resulting in significantly better light sensitivity, improved dynamic range, and superior low-light image quality. In my tests, the K-5 II excels in retaining highlight and shadow details, delivering richer color depth (DXO color depth rating of 23.8) and more natural skin tones - essential for portraiture.

Autofocus and Shooting Performance: Speed & Accuracy Tested

Let’s analyze how these cameras perform focusing on both speed and precision, factors critical for most photography genres.

Panasonic TS5

The TS5 relies on contrast-detection autofocus only, with 23 focus points but no phase detection. Face and eye detection is not available - autofocus tends to hunt more under low-light or fast-moving conditions.

• Continuous Shooting: 10 fps (buffer and AF speed limits may apply)
• Focus Modes: AF Single, AF Continuous, no manual focus option

In practice, the TS5’s AF served well for static subjects outdoors but struggled with wildlife or sports motion. It’s also limited by the fixed lens and slower aperture range (f/3.3–5.9).

Pentax K-5 II

The K-5 II features a hybrid 11-point autofocus system with 9 cross-type points, combining phase-detection and contrast detection. It includes eye detection autofocus and offers selective AF point selection, giving you precise control.

• Continuous Shooting: 7 fps, reliable for mid-speed action
• Manual Focus: Yes, with magnified LiveView assist

During wildlife and sports shoots, the K-5 II’s AF tracking proved reliable even under complex lighting and motion. It locks quickly on subjects’ eyes and maintains sharp focus through burst sequences.
