Panasonic FZ35 vs Pentax K100D Super: A Thorough Comparative Analysis for Photography Enthusiasts

Choosing the right camera involves balancing technical specifications, operational practicalities, and suitability to your photography genre or workflow. This detailed comparison between the Panasonic Lumix DMC-FZ35 (hereafter the Panasonic FZ35) and the Pentax K100D Super (Pentax K100D S) draws from extensive hands-on experience testing both cameras over varying conditions and photographic disciplines. While the FZ35 occupies the bridge camera superzoom segment, the K100D S is a classic entry-level DSLR. This article offers an exhaustive evaluation across sensor technology, autofocus, ergonomics, lens system, and more, layering real-world usability with objective testing metrics.

Overview and Design Philosophy: Bridge Superzoom vs DSLR Fundamentals

The Panasonic FZ35, released in 2010, is engineered around a fixed superzoom lens with an 18x optical zoom ranging from 27mm to 486mm equivalent focal length. Its fixed-lens design offers versatility and convenience, aiming at users who want an all-in-one solution without dealing with interchangeable lenses or complex systems.

Conversely, the Pentax K100D Super, launched in 2007, features a traditional DSLR body with an APS-C sized sensor and compatibility with Pentax K-mount interchangeable lenses. This inherently modular design caters to enthusiasts wanting incremental system expansion and optical quality via diverse lens options.

Comparing physical footprints and build reveals the FZ35’s smaller, lighter profile - moderate for a bridge camera at 397g - versus the bulkier K100D S tipping the scales at 646g. The FZ35’s compactness makes it more travel-friendly, whereas the Pentax offers a more solid DSLR feel, albeit with added heft from lens weight during use.

Sensor Technology and Image Quality

At the heart of photographic output lies the sensor and its associated image pipeline. The Panasonic FZ35's 1/2.3" CCD sensor measures just 6.08x4.56mm, significantly smaller than the Pentax’s 23.5x15.7mm APS-C sensor size, creating intrinsic differences in image quality potential.

The FZ35’s 12MP resolution on a compact sensor results in smaller pixel pitches that inherently limit dynamic range and noise performance, especially at higher ISO sensitivities. Because the sensor is CCD rather than CMOS, it offers modest noise characteristics but less flexibility in read-out speed for continuous shooting and video.

In contrast, the K100D Super’s 6MP APS-C CCD sensor, while lower in megapixels, benefits from larger pixel areas that yield superior signal-to-noise ratio, improved low-light ISO performance (native ISO 200–3200), and notably better dynamic range. This translates directly into cleaner images in shadows and highlights - crucial for demanding portrait, landscape, and event photography.

The K100D S’s sensor also enables longer shutter speeds down to 30s for night and astro photography, whereas the FZ35’s shutter caps at 1/60s on the low end, restricting long-exposure capability.

Lens Optics and Focal Range: Built-In Versus Interchangeable

The Panasonic FZ35 features a non-removable Leica-branded lens with an 18x zoom from ultra-wide 27mm to super-telephoto 486mm in 35mm equivalent terms. The lens’s maximum aperture varies from bright f/2.8 at the wide end to f/4.4 at full zoom, granting reasonable low-light and subject isolation capabilities in wide-angle shots.

Notably, the FZ35 offers macro focusing down to 1 cm, ideal for close-up nature or product photography without additional accessories. Optical image stabilization further helps freeze telephoto and macro shots, an advantage in a compact system.

The Pentax K100D S relies on the diverse Pentax KAF2 mount lenses - over 150 to choose from, spanning primes, zooms, macros, and specialty optics developed over decades. This flexibility allows precise optical tailoring but requires willingness to invest and carry multiple lenses.

Since lens quality varies by glass used, a good Pentax zoom lens can outperform the FZ35’s fixed optic in sharpness, contrast, and chromatic aberration control. The K100D does not include built-in lens stabilization but rather sensor-shift stabilization, which functions with any mounted lens.

Autofocus Systems and Operational Responsiveness

The FZ35 employs a contrast-detection autofocus system with face-detection included, but it lacks continuous AF and complex tracking. Single-point AF is the limit, and focus speed suffers in low contrast or telephoto modes.

The K100D Super benefits from an 11-point phase-detection autofocus system, an industry staple in DSLRs enabling faster, more reliable focus acquisition and continuous autofocus suitable for moving subjects. The phase-detect AF covers a wider area and allows selective point choosing or multi-area mode - offering significantly greater creative control.

In practical field testing, the K100D outperforms the FZ35 in sports, wildlife, and street photography environments that demand fast and accurate autofocus. The FZ35’s AF latency and lack of tracking make it less suitable for action photography despite its long zoom.

Continuous Shooting and Buffer Performance

Regarding burst shooting, both cameras fall short of modern high-speed standards but reflect their respective class limitations. The FZ35 offers a 2 fps continuous shooting speed - modest, rendering it ineffective for fast action but adequate for casual shooting.

The K100D S can manage 3 fps, slightly faster but limited by the 6MP output and buffer capacity. Neither supports advanced electronic shutter modes or silent shooting, and both have modest buffer depth restricting extended bursts.

Viewfinder and LCD Interface: Optical Versus Electronic

The Pentax K100D S offers a traditional pentamirror optical viewfinder with 96% coverage and 0.57x magnification, delivering bright, real-time viewing without lag or electronic noise. While not the brightest or largest viewfinder due to the pentamirror design, it provides critical framing accuracy and stable eye relief for long shoots.

The Panasonic FZ35 incorporates a small electronic viewfinder (EVF), which, although providing 100% coverage and useful overlays, suffers from lower resolution and slight lag, especially in low light or rapid panning.

LCD screens on both are fixed and non-touch, with 2.7 inches/230k dots on the FZ35 being slightly larger and higher resolution than the K100D’s 2.5 inches/210k dots. Both provide live view functionality, but only the FZ35 supports it natively, easing manual focusing.

Build Quality, Ergonomics, and Handling

Physically, the K100D Super’s more substantial size and weight contribute to its durability and balance with larger lenses. Its compact SLR shape and deeply textured grip afford comfortable extended use. The camera also includes a top LCD panel showing exposure parameters - a feature absent on the FZ35.

Ergonomically, the Panasonic FZ35 offers a bridge camera’s simplified controls, leaning toward casual shooters and point-and-shoot converts. However, the smaller size compromises grip comfort during long telephoto shooting, and the fewer physical dials limit quick manual adjustments. Its reliance on an electronic viewfinder may irritate users accustomed to optical clarity.

The control layout on the Pentax prioritizes direct dial and button access, benefiting manual exposure mode users and those who change settings frequently on the fly.

Battery Life, Storage, and Connectivity

The Panasonic FZ35 employs a proprietary rechargeable lithium-ion battery (model and exact capacity not specified) providing decent longevity for the sensor size and EVF use. It stores images on a single SD/SDHC card slot with support for internal memory.

The K100D Super operates on four widely available AA batteries, allowing field users to substitute recharged units or alkalines, a practical advantage in remote locations. Its storage is similarly on SD/SDHC cards.

Neither camera offers wireless connectivity, Bluetooth, or GPS features, limiting remote control and geotagging options. The FZ35 includes HDMI output for image playback on external displays, while the K100D lacks this functionality.
