Panasonic FS25 vs Panasonic ZS35: A Hands-On Comparison Across the Photography Spectrum

When evaluating compact cameras in the small sensor category, things can get deceptively complex. Panasonic’s Lumix lineup boasts a variety of such models, targeted for differing uses and skill levels. Today, I'm zeroing in on two “small sensor” compacts from Panasonic’s past decade: the Panasonic Lumix DMC-FS25 (“FS25”) introduced in 2009, and the Lumix DMC-ZS35 (aka Lumix DMC-TZ55) from 2014. Both wield 1/2.3” sensors but cater to somewhat different needs, price points, and feature sets.

Having extensively tested both cameras in the field and lab, I’ll walk you through how these two compacts compare - from their physical handling and core imaging tech to their performance in various photography disciplines. Whether you hunt for an affordable travel companion or a versatile everyday snapshot tool, this comparison will give you practical real-world insight.

Size and Ergonomics: Portability and Handling Matter

At first touch, these cameras shout different intentions. The FS25 is a slim, ultra-compact pocket camera, while the ZS35 is visibly chunkier with a pronounced zoom grip.

The FS25’s compactness (97 x 58 x 22 mm) and featherlight weight (148 grams) make it easy to slip in a jacket pocket or purse without bulk. However, its slender body limits physical controls - it has a rather minimalistic layout which can feel clumsy for any manual tweaks or quick adjustments. The lack of a viewfinder also nudges you to rely on composing via the LCD in bright daylight, which can be challenging.

By comparison, the ZS35 (107 x 62 x 32 mm, 305 grams) doubles down on heft to deliver a more ergonomic grip and button layout. Its larger dimensions accommodate more versatile control, including dedicated shutter speed and aperture priority modes, as well as an exposure compensation dial. It lacks a viewfinder as well, but the similarly sized but tilting LCD panel enhances framing flexibility outdoors and for tricky angles.

I found the ZS35 noticeably steadier to hold during long telephoto shooting, especially with heavier lenses. Its buttons have better spacing and tactile feedback, helpful when shooting fast action or in cooler weather while wearing gloves. The FS25 is ideal when size and convenience dominate your priorities; the ZS35 suits those who demand more control and comfort for extended shooting sessions.

Design and Controls: Intuitive or Limited?

Getting into the nitty-gritty of surface controls, the cameras differ significantly. Here is a top-down look:

The FS25 keeps things basic: mode dial, shutter release, zoom lever, and power button dominate the top surface. There’s no manual exposure mode or dedicated dials - only an automatic and scene shooting mode mix. This simplicity is a double-edged sword: it’s approachable for complete beginners but frustrating if you want creative control.

The ZS35 includes more traditional and photographer-friendly features: a mode dial with full Manual (M), Aperture Priority (A), and Shutter Priority (S) modes along with Auto and Scene options. It also sports an exposure compensation dial and a custom menu button. The layout supports speedy changes on the fly without diving into menus, a boon for enthusiasts.

Both share a 3-inch LCD screen, but the ZS35’s display is higher resolution and tiltable - ideal for composing high or low shots - while the FS25’s screen is fixed and notably lower-res, impacting clarity especially outdoors. I’ll discuss the screens in detail below.

Sensor and Image Quality: Same Size, Different Generation

Both cameras employ a 1/2.3" sensor sized at 6.08 x 4.56 mm, with an active sensor area of roughly 27.72 mm². However, the FS25 uses an older CCD sensor with 12 megapixels, while the ZS35 sports a newer CMOS sensor with 16 MP. The technical jump in sensor technology and image processing here is significant.

The CCD sensor in the FS25 renders decent daylight images, especially for casual snapshots, but struggles noticeably with noise at higher ISOs above 400 and has limited dynamic range. This is typical of early compact CCD sensors.

The ZS35’s more recent CMOS sensor yields crisper images with better color fidelity, thanks to improved microlens design and a more sophisticated image processor. I found it better at managing noise up to ISO 800 and retains more highlight and shadow details in challenging lighting. The 16MP count adds some cropping flexibility without obvious softness - a boon for wildlife or sports where tight framing is common.

Both cameras have an anti-aliasing filter to combat moiré, but the ZS35’s modern sensor architecture and enhanced processing deliver overall superior image quality. The FS25 feels decidedly “dated” here and leaned more heavily on post-processing noise reduction which softened fine detail.

User Interface and Display: The Window to Your Image

Building on the earlier mention of screens, let's explore how their LCDs support your shooting experience.

The FS25 has a 3” LCD with only 230k dots resolution, fixed in place. In sunlight, it’s markedly dim and grainy, diminishing framing confidence and preview sharpness. The UI is basic with limited exposure feedback or histogram assistance. Combining that with no touchscreen or live histogram makes it hard to achieve precise exposure or focus confirmation.

The ZS35’s 3” LCD boasts 460k dots resolution and tilts up to 180 degrees, a practical feature when shooting low angles or selfies (though no touchscreen capability). It’s brighter, clearer, and the interface is enhanced with live exposure indicators, focus peaking aids, and more granular menu settings, which I appreciated when quickly changing ISO or shutter speeds.

Neither camera offers an electronic viewfinder, a notable omission especially for outdoor shooting in bright conditions. If you often shoot under harsh sunlight, pairing these cameras with an external shade is advisable.

Autofocus and Shooting Speed: Capturing the Moment

Autofocus performance is a key differentiator, especially for action, wildlife, and street photography. Here’s my experience:

The FS25 relies on contrast-detection AF with 11 focus points and offers only single autofocus mode. It lacks continuous AF or tracking capabilities, making it best suited for still subjects. In low light or complex scenes, hunting to lock focus was common and moderately frustrating.

The ZS35 features a more capable contrast-detection system with 21 AF points, including single, continuous, and tracking AF modes. It incorporates face detection and performs noticeably better at locking onto moving subjects. In my tests, it could track a walking dog fairly reliably without focus hunting, and burst shooting at 10fps allowed capturing brief sequences of action.

Continuous AF practically never worked on the FS25, limiting its usefulness for sports or wildlife. Whereas the ZS35’s burst and AF tracking combination proved adequate for casual sports or street photography.

Lens and Zoom Capabilities: Versatility in Framing

Both cameras come with fixed zoom lenses but with quite different ranges and optical designs.

• FS25 sports a 5x zoom lens at 29–145 mm equivalent, aperture range f/3.3-5.9.
• ZS35 moves into superzoom territory with a 20x zoom spanning 24-480 mm at f/3.3-6.4.

This difference is huge. The FS25’s wide-end starts modestly telephoto, not exactly wide-angle, limiting room for sweeping landscapes or interiors. Its telephoto end stops at 145mm, useful for portraits and casual snaps but falls short of serious wildlife reach.

The ZS35’s wide 24mm start expands creative horizons dramatically – perfect for landscapes, architecture, and cramped spaces. On the telephoto side, 480mm equivalency enables shooting distant subjects, wildlife, or tight headshots without cropping. Image sharpness at telephoto is respectable given the focal length and compact size, though softness and chromatic aberrations creep in at full zoom.

For macro capabilities, the ZS35 focuses as close as 3cm, better than the FS25’s 5cm minimum, allowing finer detail capture in small subjects or flowers. Both cameras have optical image stabilization (OIS), which is more critical on the ZS35 to offset camera shake at long zooms - in my use, OIS effectiveness was similar and effective.

Burst Shooting and Shutter Speeds: Responsiveness

The FS25 offers a maximum burst rate of about 2 frames per second, which quickly bogs down buffer capacity. Shutter speed tops out at 1/2000 sec, insufficient for freezing extremely fast action like sports or bird flight.

On the other hand, the ZS35 can shoot at up to 10 fps, a major boon for capturing split-second expressions or action bursts. It also offers shutter speeds from 4 sec up to 1/2000 sec, covering a broader range of creative exposures.

For sports or wildlife shooters, the ZS35’s faster frame rates and AF tracking modes provide significantly improved capabilities.

Video Shooting: Compromises and Capabilities

Video is a secondary consideration for many compact camera buyers but can add to versatility.

The FS25 records video at a max resolution of 848×480 pixels at 30 fps, encoded in Motion JPEG format, which is very basic by 2024 standards. Video quality is low, with visible compression, limited detail, and little dynamic range. No image stabilization benefits video.

The ZS35 upgrades video capture to Full HD 1920×1080 at 30p framed in MPEG-4 format, delivering smooth footage with distinguishable detail and color accuracy. Optical stabilization also works during video recording, a plus. However, neither camera offers microphone or headphone ports, and manual audio controls are absent.

For casual family clips or travel videos where convenience outweighs pro features, the ZS35 is the more capable option. The FS25 is adequate only for quick, low-res home movies.
