Panasonic TS20 vs Pentax K-5 IIs: A Deep Dive Into Two Cameras at Opposite Ends of the Spectrum

Whether you’re hunting for a rugged point-and-shoot or a professional-grade DSLR, few comparisons highlight the broad diversity of photographic tools better than the Panasonic Lumix DMC-TS20 (TS20) and Pentax K-5 IIs. Released roughly a year apart - 2012 for the TS20, 2013 for the K-5 IIs - these cameras cater to very different audiences, feature sets, and use cases. And yet, placing them side-by-side is a fascinating exercise in understanding what you get when you prioritize portability and toughness, versus image quality and professional control.

Having tested thousands of cameras over the years, I find that this particular match-up exemplifies how much camera technology and design can diverge, even with the same 16-megapixel resolution. So, buckle up as I tap into both hands-on experience and technical testing to walk you through everything that matters about these two.

Size, Build, and Ergonomics: From Pocket Buddy to Professional Workhorse

The first - and perhaps most immediately noticeable - difference is the physical size. The Panasonic TS20 is a compact waterproof camera, measuring just 101 x 58 x 19mm and weighing 142 grams. It’s roughly the size of a thick deck of cards, designed to accompany you on hikes, pool parties, and anywhere else you might encounter water, dust, or even freezing temperatures. It’s approved as waterproof, dustproof, shockproof, and freezeproof - toughness is its middle name.

By contrast, the Pentax K-5 IIs is a mid-size DSLR weighing 760 grams and measuring 131 x 97 x 73mm. Ergonomically, this kind of heft feels substantial but perfectly balanced in hand, especially when paired with professional lenses. The magnesium alloy body with environmental sealing offers durability, though not the rugged “throw it in a creek” kind. Instead, it’s designed for photographers who demand reliability in adverse weather but within a more traditional DSLR framework.

The TS20’s fixed lens and limited controls reflect its consumer-friendly approach, whereas the K-5 IIs has an extensive grip, top-plate dials, and customizable buttons that cater to pros who need quick access under pressure.

Intuitive Controls vs Simplified Simplicity

Looking at the top view of these cameras makes the difference in operation crystal-clear. The TS20 offers a simplified interface, with minimal buttons and no dedicated dials for aperture or shutter speed. Exposure modes are locked down to “auto” with some basic scene presets and limited manual overrides. It’s designed for quick point-and-shoot use where you just want reliable photos without fuss.

The Pentax K-5 IIs, on the other hand, is all about giving you control. Exposure compensation, shutter priority, aperture priority, and full manual modes are there, alongside the robust PRIME II image processor driving a 7 frames-per-second burst - a feature the TS20 simply cannot come close to. The K-5 IIs’s illuminated buttons (though not present in this model) are a nod towards low-light operation, but you still get excellent tactile feedback.

The lack of touchscreen on both cameras isn’t surprising given their age, but the K-5 IIs’s dedicated top LCD and command dials make for a much faster workflow in fast-paced professional scenarios.

Sensor Technology and Image Quality: Tiny CCD vs Large CMOS, and What That Means

Despite both cameras boasting roughly 16-megapixels, their sensors couldn’t be more different. The TS20 uses a 1/2.3-inch CCD sensor that measures 6.08 x 4.56mm with a sensor area of about 28 mm². In contrast, the Pentax employs a significantly larger APS-C CMOS sensor measuring 23.7 x 15.7mm with a whopping 372 mm² area - more than 13 times larger.

Why does this matter? Sensor size directly impacts image quality in numerous ways:

• Dynamic range: The K-5 IIs boasts a DxOMark dynamic range score of 14.1 EV vs. no data available for the TS20 CCD sensor, but historically such small sensors show narrower dynamic ranges leading to quicker highlight clipping and loss of shadow detail.

• Low-light performance: The K-5 IIs excels up to native ISO 12800 and boosted to 51200 with usable noise levels thanks to backside-illuminated CMOS design and lack of anti-alias filter, which helps sharpen detail. The TS20 tops out at ISO 6400 but with noisy, likely unusable images beyond ISO 800.

• Color depth: The Pentax achieves 23.9 bits, ensuring vibrant and natural color gradations. CCD sensors tend to struggle at this level on small formats.

• Resolution and pixel pitch: While both deliver 16MP, pixel pitch on the K-5 IIs is larger, aiding superior noise performance and better signal-to-noise ratio.

In practice, this translates to striking differences in image quality. The TS20 is great for casual snapshots in well-lit conditions but struggles to deliver clean images in challenging light. The K-5 IIs produces crisp, detailed photographs suitable for professional print and use.

Autofocus and Shooting Performance: Contrast Detection Versus Hybrid Phase-Detection

Autofocus systems often define how effectively a camera can capture fleeting moments. The TS20 uses a contrast-detection AF system supported by 23 focus points, whereas the K-5 IIs incorporates a hybrid phase-detection system with 11 focus points, 9 of which are cross-type.

Phase-detection autofocus is well known for its speed and tracking accuracy, critical for sports, wildlife, and other dynamic subjects. Contrast detection offers precision but tends to be slower and prone to hunting, especially in low contrast or low light conditions.

The TS20’s continuous shooting is limited to a meager 1 frame per second - fine for leisurely snapshots. The K-5 IIs offers a healthy 7 fps, supporting action photography and fast-paced shooting scenarios.

Additionally, the K-5 IIs features advanced autofocus modes including face detection, selective AF points, and tracking AF that the TS20 simply lacks. This makes a drastic difference when shooting moving subjects.

LCD and Viewfinder: Precision Versus Portability

Both cameras feature fixed TFT LCDs, but the differences in size, resolution, and usability for composition are significant:

• The TS20’s 2.7-inch screen has just 230k dots - adequate at best for framing and playback, but lacking clarity and poor in bright outdoor viewing.

• The K-5 IIs offers a 3-inch LCD with 921k dots, making critical focus checks and menu navigation a much smoother experience.

What the TS20 loses in LCD clarity, it attempts to make up with live view for framing, but it lacks an electronic or optical viewfinder entirely. The K-5 IIs includes a traditional pentaprism optical viewfinder covering 100% field of view with 0.61x magnification - an invaluable asset for precise composition and battery savings during long shoots.

Lens Ecosystem and Versatility: Fixed vs Interchangeable System

The TS20 is a fixed-lens camera with a built-in 25 to 100mm (35mm equivalent) zoom lens with max apertures from f/3.9 to f/5.7, suitable for casual wide-angle to short telephoto. Its macro capability reaches as close as 5 cm, making it handy for impromptu close-ups.

The K-5 IIs shines here with a fully interchangeable Pentax KAF2 mount, compatible with over 151 lenses - that’s a vast array including primes, fast apertures, tilt-shift, macro, and super-telephoto lenses. The APS-C sensor’s 1.5x crop factor further extends the reach of telephoto lenses, important for wildlife and sports shooters.

Lens choice radically defines the photography types you can excel in. The TS20’s limitation to a fixed, modest zoom restricts creative control and optical quality. The K-5 IIs gives you professional glass options tailored to exactly the image characteristics you want.

Battery Life and Storage: Small but Sufficient vs Marathon Performer

The TS20’s battery life stands at around 250 shots per charge - reasonable considering its simplicity but limiting for extended shoots. This compact battery is user-replaceable but smaller capacity means multiple spares for heavy use.

In contrast, the K-5 IIs offers an impressive 980 shot battery life using its D-LI90 pack - almost four times more - and supports power via optional AC adapters or battery grips. This is essential for professionals who shoot events or travel days on end without constant charging.

From a storage perspective, both accept SD/SDHC/SDXC cards and feature a single card slot, which is routine for their respective niche: casual shooter and mid-level pro DSLR.

Environmental Sealing and Weather Resistance: Built For Extremes vs Controlled Conditions

If your adventures lead you to the lakeshore or mountain trail, the TS20’s waterproof (up to 10m depths), dustproof, and shockproof design make it an ideal companion. It even includes freezeproofing - meaning it’s happy in sub-zero conditions.

The Pentax K-5 IIs also offers weather sealing, but it is not waterproof or freezeproof. Its sealing protects against dust and moisture, so you can shoot confidently in misty rain or dusty environments, but immersion is certainly off-limits. Keep this in mind if your photography takes you underwater or into extreme environments without a housing.

Image Stabilization and Flash Systems: Optical Versus Sensor-Based IS

One interesting detail: both cameras feature image stabilization, but implemented differently.

• The TS20 has optical stabilization built into its lens system, which helps reduce blur from shaky hands but is relatively basic.

• The K-5 IIs incorporates sensor-shift (in-body) stabilization, which can work with any attached lens, including legacy manual focus glass - a big plus for versatility, especially with slow lenses or telephoto glass where stability is critical.

Regarding flash, the TS20 has a built-in flash with a modest range of 4.4 meters and no hot shoe, limiting external or creative lighting.

The K-5 IIs includes a powerful built-in flash with 13-meter range at ISO 100 and a hot shoe for external units, supporting advanced flash modes including high speed sync, wireless slave, and rear curtain sync. This gives professionals significant lighting flexibility.

Video Capabilities: Casual Clips vs Prosumer HD

The TS20 shoots HD video at 1280 x 720 pixels at 30fps, encoded in MPEG-4 - a basic setup aimed at casual users wanting simple videos.

The K-5 IIs delivers full HD 1920 x 1080 resolution video at 25fps (PAL), slightly more versatile frame rates at 720p and VGA, and records in Motion JPEG format. It also has a microphone input jack, allowing higher quality audio capture - a feature enthusiasts and pros appreciate.

Neither camera supports modern 4K recording or advanced video codecs, but for its era and category, the K-5 IIs stands out for more serious video work.
