Panasonic Lumix S5 vs Pentax K100D Super: A Thorough Camera Comparison for Every Photographer’s Journey

Choosing your next camera is a significant step, and with options spanning generations and technologies, it can feel overwhelming. Today, we dive deep into two very different cameras: the Panasonic Lumix S5, a modern full-frame mirrorless powerhouse, and the Pentax K100D Super, a classic APS-C DSLR from 2007. While these cameras target very different users and eras, examining them side by side offers unique insight into how camera technology has evolved and how each machine continues to serve distinctive photography needs.

Whether you’re a professional stepping up to mirrorless, a beginner curious about entry-level DSLRs, or a seasoned enthusiast aiming to understand practical differences, we’ll guide you through sensor tech, ergonomics, autofocus, lenses, and shooting performance across genres. Our hands-on experience testing thousands of cameras shapes this authoritative comparison - let’s get started.

Holding Your Camera: Sizes, Designs, and Handling

First impressions matter, especially once you start shooting seriously. The ergonomic design, weight, and control layout influence comfort and usability throughout a session.

The S5’s body is modestly larger and heavier than the Pentax but designed thoughtfully for prolonged handheld use. The Magnesium alloy construction with environmental sealing translates to durability and reliability under varied weather conditions - key for landscape and travel photographers. Meanwhile, the K100D Super is lighter and more compact, making it a low-fatigue companion for beginners or casual shooters but without the benefits of weather resistance.

While both offer manual focus compatibility and robust control sets, Panasonic’s incorporation of a fully articulated touchscreen enhances creative framing flexibility - a feature missing from the fixed, non-touchscreen on the Pentax. These physical and interface differences set the stage for how each camera adapts to your shooting style.

Viewing and Framing Your Shot: Viewfinders and LCD Screens

The quality and responsiveness of the viewfinder and LCD screen are vital, especially when composing under different lighting or shooting scenarios.

The Panasonic S5’s electronic viewfinder offers a bright, detailed preview with live exposure, focus peaking, and histogram overlays that can speed up your workflow and reduce guesswork - especially helpful in challenging light or video mode. This advantage over the K100D’s optical pentamirror finder means you get a more accurate representation of exposure and framing before pressing the shutter.

Moreover, the S5’s large articulated touchscreen invites creativity - perfect for shooting at high or low angles, video vlogging, or quick camera setting adjustments without wrestling with buttons.

The K100D’s fixed 2.5” screen is functional but basic, reflecting its age and intended market. Its optical viewfinder, while bright and lag-free, provides partial frame coverage (96%) and limited exposure info. This sets a boundary on precision composition, though some photographers appreciate the direct optical experience.

Sensor and Image Quality: The Heart of the Camera

A critical aspect is sensor technology - it dictates how much detail, dynamic range, and low-light capability your photos can have.

The S5’s full-frame CMOS sensor represents a significant leap in image quality, offering finer resolution (24MP vs 6MP) that translates to larger print sizes and cropping flexibility. Without an anti-aliasing filter, it also produces sharper images with more fine detail, though with slight care needed for moiré patterns in some situations.

In contrast, the Pentax K100D Super’s CCD sensor, while praised at its release for color richness, now shows its limits with lower resolution and noisier images at higher ISOs. The camera’s max native ISO tops at 3200 without expansion, which constrains low-light shooting.

Dynamic range on the S5 also far surpasses the ‘old school’ CCD sensor, providing richer tonal gradations in highlights and shadows. For landscape and portrait photographers requiring subtle color rendition and post-processing flexibility, the S5 is a clear winner.

Autofocus Systems: Precision, Speed, and Tracking in Action

How your camera locks focus affects nearly every photographic genre - from fast-paced sports to delicate macro work.

Panasonic’s advanced depth-from-defocus (DFD) technology in the Lumix S5 delivers fast and accurate autofocus with 225 points spread across the frame. This system excels at detecting faces and eyes, crucial for portrait and wildlife photographers who want sharp focus locked on fast or unpredictable subjects. The S5’s AF tracking works robustly in continuous shooting, giving dependable results when capturing movement.

The K100D Super uses an older phase-detection AF system with 11 points that’s competent but limited. It lacks face or eye detection, and its tracking capabilities are basic at best. While sufficient for general photography and static subjects, the Pentax won’t keep pace in sports, wildlife, or video autofocus demands.

If autofocus performance is a priority, especially for action or fast-moving subjects, the Panasonic S5 stands far ahead through modern algorithms and focus assist technologies.

Burst Shooting and Shutter Speed: Capturing the Decisive Moment

Fast frame rates and shutter timing precision matter in sports, wildlife, and candid photography.

The Lumix S5’s 7 fps burst is over double the 3 fps on the K100D, enabling you to catch quick action sequences more reliably. The electronic shutter option also allows silent shooting, an asset in discreet environments like weddings or wildlife hides.

Its maximum shutter speed of 1/8000s permits shooting wide open at bright midday sun without ND filters, giving better control over depth of field. The Pentax’s 1/4000s top shutter speed is slower and without silent options, which restricts creative and low-noise scenarios.

For sports and wildlife shooters, the Panasonic’s faster burst and higher shutter speeds are significant upgrades.

Lens Ecosystem and Compatibility: Your Creative Toolkit

Lens choice defines the creative possibilities with your camera.

Pentax boasts a vast legacy lens collection with over 150 native and vintage K-mount lenses, making it attractive if you want affordable glass that can cover everything from macro to telephoto. Its APS-C crop means lenses designed for this format work optimally without waste.

The Panasonic Lumix S5 uses the Leica L-mount, a newer but rapidly expanding ecosystem supported by Panasonic, Sigma, and Leica itself. Although fewer lens options exist relative to legacy mounts, the quality of available lenses and full-frame coverage enables professional-grade looks.

For those emphasizing future-proofing and professional-quality glass, investing in Panasonic’s system is wise. However, Pentax’s lens library remains appealing for budget-conscious beginners or collectors of classic optics.

Video Capabilities: Shooting Beyond Stills

In today’s content world, video performance can be as crucial as still photography.

The Panasonic S5 is built to handle impressive 4K video at 60p, with professional controls and dual headphone/microphone ports for monitoring and sound capture. It also incorporates 5-axis sensor stabilization, which smooths handheld video footage and supports slower shutter speeds in stills.

In contrast, the Pentax K100D Super has no video capabilities, reflecting technological limits of its time. If hybrid shooting or video content creation matters to you, the S5 opens doors that the Pentax simply cannot.

Battery Life, Storage, and Connectivity

Long shooting sessions benefit from strong battery performance and storage options, alongside wireless connectivity for image transfer.

The Lumix S5 offers solid battery life for mirrorless standards along with the convenience of USB charging - a feature you’ll appreciate when traveling or during extended shoots. Dual card slots provide worry-free redundant storage or backup, critical for professional use.

The Pentax’s reliance on ubiquitous AA batteries may appeal in remote locations with no power access, but its single SD card slot and lack of wireless features mark it as less flexible in today’s connectivity-driven landscape.
