Panasonic Lumix DMC-FX90 vs Samsung ST150F: A Deep Dive into Small Sensor Compact Cameras

The realm of small sensor compacts often invites a blend of portability, casual usability, and decent imaging performance. Today, I’m unpacking two handheld contenders - the Panasonic Lumix DMC-FX90 and the Samsung ST150F. Both launched in the early 2010s, these cameras cater to enthusiasts and casual shooters who want a pocketable solution without emptying their wallets.

I’ve spent ample time putting these two through their paces - measuring not only technical specs but how those translate into everyday photography scenarios. In this detailed comparison, I aim to equip you with clear, experience-based insights to choose the right camera, whether you’re focused on portraits, landscapes, video, or travel snapshots.

Let’s begin with how these cameras look and feel in the hand.

Handling and Ergonomics: Small Packages, Different Designs

At first glance, both the FX90 and the ST150F embrace compactness, but their physical dimensions and grip comfort reveal subtle design philosophies:

The Panasonic FX90 measures 102 x 56 x 22 mm and weighs around 149 grams, while the Samsung ST150F is slightly smaller and lighter at 94 x 58 x 18 mm and 114 grams. The FX90's larger footprint affords a slightly more substantial grip surface, which I found beneficial in reducing hand fatigue during longer shoots. The Samsung’s slender form, on the other hand, slips more easily into tighter pockets - making it an attractive option for travelers prioritizing discreteness and ultra-portability.

The Panasonic’s body incorporates a touchscreen - a feature absent on the Samsung - which adds an intuitive element to focusing and menu navigation despite its relatively low 460k-dot resolution. The Samsung’s 230k-dot screen, while adequately sized at 3 inches, falls short in sharpness and responsiveness.

Let’s visually inspect their top decks and controls for further insight:

The FX90 boasts well laid-out buttons with tactile feedback, making it straightforward to toggle flash modes, zoom, and access playback. The inclusion of an optical image stabilization toggle (enabled by default) and a dedicated video record button adds to user friendliness. Samsung’s minimalist button array keeps complexity low, but the absence of quick-access physical controls for ISO or exposure compensation limits creative control.

Neither camera sports an electronic viewfinder, a common omission in this category to keep sizes manageable. Instead, both rely heavily on their LCDs for composition.

Sensor and Image Quality: Two CCDs, Different Resolutions

This is where things begin to diverge technically. Both cameras feature a 1/2.3” CCD sensor, but differ in resolution and subtle sensor design:

The FX90’s sensor offers 12 megapixels with maximum native ISO 6400, while the ST150F ups the count to 16 megapixels but limits ISO max to 3200. The slightly higher resolution on the Samsung theoretically allows more cropping flexibility and larger print sizes, but CCD sensors of this vintage inherently struggle with noise and dynamic range compared to modern CMOS variants.

From rigorous lab tests and on-the-road shooting in varying light, the Panasonic’s 12MP sensor produces cleaner images at higher ISOs, a reflection of its better noise handling despite lower resolution. The FX90’s effective optical image stabilization also helps maintain sharpness during longer exposures - a clear advantage for landscapes and indoor shots.

Samsung’s sensor packs in more pixels which can yield detailed daylight captures, but noise becomes a limitation quickly past ISO 400, making it less viable in dim conditions.

Looking at both cameras' raw white balances and color reproduction, Panasonic’s color depth feels more natural, especially in skin tones and rich foliage.

Rear Screen and Interface Usability: LCD as Your Eye

A camera’s rear screen is the lifeline for framing shots and navigating menus. Here’s a side-by-side to better appreciate each model’s offering:

The FX90’s 3-inch 460k-dot touchscreen is notably sharper and more responsive. It supports touch-to-focus, an appealing convenience for fast-paced street or travel photography. The Samsung’s 3-inch 230k-dot QVGA LCD is serviceable but doesn't inspire confidence in bright outdoor conditions.

Menus across the Panasonic feel better organized with faster response times, while Samsung’s simpler interface can feel sluggish, especially when scrolling through settings. Panasonic is also unique here for providing several aspect ratio options (1:1, 4:3, 3:2, 16:9), versus Samsung’s limited choices, helping photographers experiment with composition styles.

Autofocus Systems: Responsiveness and Accuracy

Moving onto focus precision and speed - two critical metrics for wildlife, sports, and street photography.

The FX90 employs a contrast-detection AF system with 23 focus points, including multi-area and center AF modes, plus basic continuous autofocus and tracking. It lacks face or eye detection but compensates with a live view plus touch-based AF.

Samsung’s ST150F also uses contrast-detection but offers selective, center-weighted, and multi-area AF modes with face detection - a notable advantage for shooting portraits where nail-biting accuracy on faces is paramount.

In practical shooting tests of fast-moving subjects and challenging light, Panasonic's autofocus is appreciably faster to lock on static and slow-moving targets, aided by its dedicated AF tracking. Samsung occasionally hunts in lower light and doesn’t support continuous AF, somewhat holding it back for dynamic scenes or wildlife.

Both cameras do not support manual focus, limiting control in macro or artistic portraits.

Optics and Zoom Range: Versatile but Unremarkable

Both cameras feature fixed zoom lenses with nearly identical ranges:

• Panasonic FX90: 24-120 mm equiv., f/2.5–5.9
• Samsung ST150F: 25-125 mm equiv., f/2.5–6.3

The difference here is negligible and typical for compact zooms of this category. Panasonic’s slightly faster maximum aperture at the telephoto end offers modest edge in low-light portraits or isolated subjects.

Lens quality on the Panasonic yields marginally sharper images toward the wide and mid focal lengths, with less noticeable distortion. Samsung’s optics are quite serviceable but edges soften slightly at extremes of the zoom, contributing to slightly less resolving power.

Neither camera supports external lenses or adapters.

Burst Rate and Continuous Shooting: Catching the Action

Action photographers will want to know if these cameras can keep pace with fleeting moments.

Panasonic FX90 offers 4 frames per second (fps) in continuous mode - admirable for a compact of this era. Samsung doesn’t officially specify burst rates and lacks continuous autofocus, so it’s less suited for high-speed shooting. This difference sets Panasonic ahead for casual sports or wildlife shooters who want to capture sequences.

Video Capabilities: Full HD vs HD

Video quality is often the Achilles’ heel of compact cameras, but these models surprise us now and then.

Panasonic FX90 records up to Full HD 1080p at 60fps, using MPEG-4 and AVCHD formats - offering smoother motion and better compression. Samsung’s ST150F maxes out at 720p HD at 30fps, with MPEG-4 H.264 encoding.

Neither camera has a microphone or headphone port, limiting audio control. Panasonic’s optical image stabilization and faster frame rate combination delivers better handheld video footage with fewer jitters.

Despite no 4K or advanced video features, the Panasonic FX90 is preferable for casual videographers seeking lightweight options.

Battery Life and Storage: Practical Considerations

Battery longevity and storage flexibility often make or break the shooting experience, especially out in the wild or on travel.

Panasonic’s FX90 uses a dedicated battery pack, rated approximately at 200 shots per charge (under CIPA standards). It supports SD/SDHC/SDXC cards for expandable storage.

Samsung ST150F uses a less-documented battery type, but real-world testing suggests shorter endurance, especially given the lack of power-saving optical stabilization. It relies on microSD/microSDHC/microSDXC cards, which are smaller and usually cost less but sometimes slower for writing large files.

Users venturing on long photographic tours will need spare batteries or external chargers for both, but Panasonic's battery holds slightly better under moderate use.

Connectivity and Extras: Wireless and Ports

Both cameras come with built-in wireless connectivity, but the implementation is rudimentary. Neither supports Bluetooth or NFC, so transferring images via Wi-Fi requires the dedicated app or cumbersome methods.

Panasonic includes a mini HDMI port facilitating playback on TVs - a boon for reviewing images on larger screens. Samsung lacks this feature.

USB 2.0 supports tethered file transfers on both but don’t expect lightning-fast speeds.

Both cameras omit GPS tagging and don’t provide ruggedized weather sealing, logical omissions considering their compact class but worth noting for travelers needing durability.

Real-World Performance Across Photography Genres

With the technical groundwork laid, let’s explore how these cameras actually perform when used for different photography types.

Portrait Photography

Panasonic’s FX90 excels with pleasing skin tones, thanks to its balanced color rendering and lens speed advantage at the wide end. Its touch-enabled AF lets you lock onto faces quickly, though lack of eye detection is a drawback compared to modern compacts.

Samsung offers face detection but tends to capture cooler, less flattering portraits. Its f/2.5 aperture at wide angle helps in low light, but image noise and lens softness limit portrait sharpness at 125mm equivalent.

Landscape Photography

The Panasonic’s better dynamic range and noise control allow for richer, more detailed landscapes, especially under mixed lighting. Optical stabilization supports handheld landscape shots without tripod fuss.

Samsung’s higher megapixel count seems tempting but is offset by lower ISO tolerance and a wider aperture drop off, limiting usage in dawn/dusk scenarios. Lack of weather sealing affects prolonged outdoor use for rugged landscapes.

Wildlife and Sports Photography

Neither camera is a powerhouse for wildlife or sports, but Panasonic’s 4fps burst and swift contrast detection autofocus keep it in the race for casual action. Samsung’s slower focusing and no continuous AF leave it behind this category.

Street Photography

Both shine in their discreetness, but Panasonic’s touchscreen and exposure control edge it ahead for spontaneous shooting. The Samsung’s smaller size favors stealth but less responsive controls slow reaction times.

Macro Photography

Panasonic supports macro focusing down to 3cm, enabling fairly close close-ups with decent detail - backed by stable image stabilization. Samsung’s lack of macro specs and less precise AF systems reduces reliability for true macro work.

Night and Astro Photography

Sony CCD-based compacts like these are generally limited in high ISO and long exposure. Panasonic’s higher ISO ceiling (6400 vs 3200) and optical stabilization provide a marginal boost, but noise and dynamic range constrain performance. Neither supports bulb mode or specialized astro settings.

Video

Again, Panasonic comes out ahead with 1080p 60fps video and stabilization, making it suitable for casual video storytelling. Samsung's 720p at 30fps is functional but lacks polish.

Travel Photography

The Samsung’s lighter, thinner design wins points for minimalism, but longer battery life and better overall image quality on Panasonic justify its slightly larger size for serious travel users.

Professional Workflows

Neither camera supports RAW capture or advanced file formats, limiting their use in professional post-processing workflows. They are best viewed as secondary or backup cameras, or for on-the-go casual work.
