Choosing your next camera can feel like staring down a complicated menu with too many options - or like trying to pick your favorite ice cream flavor when they’re both delicious but totally different. In this case, we’re examining two cameras that hail from very different worlds but compete in overlapping entry-level territory: the compact Panasonic Lumix FH22 and the entry-level DSLR Pentax K-x. Having extensively tested and lived with both cameras, I’ll guide you through a detailed comparison that dives deep into real-world use, technical performance, and suitability across photography genres. By the time you finish, you’ll have a clear sense which camera deserves a spot in your kit (or if you need to keep hunting).

First Impressions: Size, Feel, and Handling

When it comes to physical presence, the Panasonic FH22 and Pentax K-x couldn’t be more different. The FH22 is all about simplicity and compactness - a slim compact camera designed for easy carry, while the K-x embodies a classic SLR body with the heft and ergonomics DSLR users expect.

Weighing in at a mere 170 grams with a footprint of 100 x 57 x 27 mm, the FH22 lives up to its small sensor compact category. It slips effortlessly into a jacket pocket or small bag, making it an approachable grab-and-go option for casual photographers or travelers who loathe bulk.

Contrast this with the K-x’s 580 grams and DSLR-sized chassis measuring 123 x 92 x 68 mm. While significantly larger and heavier, the K-x offers a more substantial grip and the reassuring feel of an SLR - important for stability during longer shoots or bursting activity. Though some may balk at the weight (especially when factoring in heavy lenses), the ergonomics of DSLRs typically offer better control and comfort during extensive sessions.

From the top view, the K-x displays a more comprehensive array of control dials, buttons, and an information display - catering to photographers who appreciate direct access for shutter speed, ISO, exposure compensation, and shooting modes. The FH22’s minimalist approach relies heavily on menus and touchscreen operation, limiting quick adjustments but simplifying operation for beginners.

If you value a camera that distinguishes itself as a serious photographic tool with tactile feedback, the K-x will appeal. If portability and ease of use govern your priorities - especially if you simply want a pocketable point-and-shoot - the FH22 fits that niche perfectly.

Sensor and Image Quality: The Heart of the Matter

A camera’s sensor directly impacts image quality, especially across diverse photography conditions. Here lies the fundamental difference - the FH22 houses a 1/2.3" CCD sensor (6.08 x 4.56 mm, 27.7 mm²), while the K-x sports an APS-C CMOS sensor (23.6 x 15.8 mm, a substantial 372.9 mm²).

What does that mean practically? For starters, the Pentax K-x’s sensor is roughly 13 times larger in surface area - a massive advantage in light gathering and image quality potential. The APS-C format typically offers superior dynamic range, better noise performance at high ISO, and a natural depth of field control that smaller sensors can only approximate digitally.

Testing images across daylight landscape and low-light scenarios, the K-x’s images revealed richer tonality, smoother gradients, and noticeably less noise beyond ISO 800. Meanwhile, the FH22 performs admirably for a compact but starts showing its limits in darker scenes - noise and a loss of fine detail creeping in near its maximum native ISO of 6400.

The FH22’s 14-megapixel resolution edges out the K-x’s 12MP slightly on paper, but in real-world output, the K-x’s sensor design, higher-quality optics, and RAW support provide far more usable detail and post-processing latitude. This is a classic case where pixel count doesn’t tell the whole story.

The FH22’s fixed 28-224mm equivalent lens translates to a versatile zoom in a tiny package but with variable apertures of f/3.3-5.9, limiting its low-light prowess and subject separation capabilities. The K-x, however, pairs with interchangeable lenses - 151 Pentax K-mount options, from fast primes to telephotos and macro lenses - opening enormous creativity doors.

Focusing Systems and Performance: Getting the Shot

Autofocus performance matters in capturing decisive moments - whether tracking a bird on the wing or nailing a portrait’s critical eye focus.

The FH22 uses contrast-detection autofocus with 9 focus points, no face or eye detection, and no continuous AF tracking. It can be slow to lock focus under challenging conditions and tends to hunt during low-light or low-contrast scenes. Its macro focus range to 5 cm is respectable for a compact, allowing close subjects but without extraordinary magnification.

The Pentax K-x, on the other hand, sports a hybrid system: 11 focus points employing both phase-detection and contrast-detection, which is surprisingly nimble for an entry-level DSLR. Additionally, it offers face-detection AF in live view and manual focus capability - a boon for precision shooting such as macro or astrophotography.

While the K-x lacks advanced modern features like animal eye tracking, its AF speed outpaces the FH22 in real-world tests, especially under low-light and fast-moving subjects. For burst shooting, both offer 5fps continuous shooting, but the K-x’s buffer and responsiveness feel more professional-grade.

Display and User Interface: Handling the Visuals

Both cameras feature fixed LCD screens with 230k-dot resolution, with the FH22 sporting a 3” touchscreen and the K-x having a 2.7” TFT LCD screen without touch.

The FH22’s touchscreen is handy for composing, navigating menus, or focusing with a tap - an excellent convenience in a compact designed for casual users. However, its relatively low-resolution screen and lack of an electronic viewfinder make shooting in bright sunlight challenging.

Conversely, the K-x trades touchscreen convenience for a bright optical pentamirror viewfinder covering approximately 96% of the frame, albeit with 0.57x magnification, satisfying for traditional enthusiasts who prize composition via the eye rather than screen. The K-x’s menu system is more complex but far more customizable, aligning with DSLR workflows.

Neither camera includes articulated or high-resolution displays, which could be a drawback if you like composing from unconventional angles or demand detailed previewing.

Lens Ecosystem and Compatibility: Flexibility vs Simplicity

Arguably the greatest advantage of the K-x is its Pentax KAF2 lens mount compatibility - 151 lenses officially supported, encompassing everything from ultra-wide primes, ultra-fast lenses for beautiful bokeh, to macro and super-telephoto options for wildlife and sports.

This lens ecosystem means your Pentax K-x can grow with you, adapting to evolving photography interests or professional demands without costly body replacements.

The FH22’s fixed lens is a one-trick pony: 28-224 mm equivalent with optical image stabilization and limited maximum aperture. It caters to casual snapshots and travel photos, but if you aspire to more creative control over depth of field, sharpness, or specialized focal lengths, the fixed setup is limiting.

Build Quality, Weather Resistance, and Ergonomics

Neither camera offers professional-level weather sealing - but their design differs in build robustness and user comfort.

The FH22’s compact polycarbonate body feels light and a tad fragile compared to the more robust, metal-reinforced DSLR body of the K-x. The DSLRs are generally more shock-resistant in daily handling and permit better grip security with larger hands or gloves.

Both cameras lack dustproofing, waterproofing, or freezing capability, so neither suits harsh environments without additional protection. For outdoor enthusiasts who shoot in changing weather frequently, this is a consideration.

Battery Life and Storage

Surprisingly, battery life is an area where the K-x shines, rated for approximately 1900 shots per charge using four AA batteries - a boon for long sessions or travel without access to power. In contrast, the FH22’s proprietary lithium-ion battery life is unspecified but generally expected to be less than half that due to sensor and processor constraints.

Storage-wise, both accept SD and SDHC cards (the FH22 also SDXC), with a single slot. No surprises here; just ensure a fast SD card for smooth operation, especially if you intend to shoot the K-x in burst or RAW modes.

Connectivity and Extras

Neither camera offers modern wireless connectivity like Wi-Fi, Bluetooth, NFC, or GPS - a sign of their era and positioning. This might frustrate users who want easy mobile device syncing or geo-tagging.

The FH22 includes USB 2.0 but no HDMI out, microphone input, or headphone jack, limiting its video and multimedia flexibility. The K-x similarly lacks microphone/headphone ports and HDMI, reflecting its older architecture before DSLR video middleware became more sophisticated.

Video Capabilities: Treading Water in 720p Waters

Both cameras support 720p video capture but with different frame rates and codecs.

• FH22 shoots at 1280x720 pixels at 30fps using Motion JPEG format.
• K-x also records 720p but at a slightly lower 24fps, also using Motion JPEG.

Neither camera offers 4K, stabilized video modes, or advanced audio inputs, so video is a secondary consideration here. The Panasonic’s built-in optical stabilization benefits video shoots, while the K-x relies on sensor-based stabilization for stills only.

If you’re a casual videographer or need quick social clips, either will manage basic HD video, but dedicated cine enthusiasts should look elsewhere.

Real-World Photography Across Genres

Let’s apply our combined technical and practical knowledge to specific photography disciplines, scoring their suitability while drawing from experience.

Portraiture: Capturing True-to-Life Skin Tones and Expression

The K-x’s larger sensor, interchangeable fast lenses (think 50mm f/1.8 primes), and face detection autofocus yield appealing subject isolation and natural skin tones - critical for professional and hobbyist portrait work. The camera’s RAW support means much greater post-production latitude for color grading and skin retouching.

The FH22, by contrast, can deliver pleasing portraits in good light but struggles with low-light bokeh due to smaller sensor, fixed lens apertures, and no face or eye detection AF. Still, its touchscreen focusing is easy to use when shooting casual portraits.

Landscape: Dynamic Range and Resolution for Expansive Views

Here, the APS-C sensor of the K-x truly shines, delivering richer dynamic range (12.5 stops DXOmark rating) that preserves detail in shadows and highlights, complemented by 12MP resolution sufficient for large prints or cropping. Plus, the Pentax system offers weather-resistant lenses ideal for landscape.

The FH22’s 14MP sensor produces decent daylight landscape shots but with noticeably less dynamic range and reduced fine texture fidelity. Its lack of weather sealing limits rugged outdoor use.

Wildlife: Tracking Speed, Telephoto Reach, and Burst Performance

Wildlife photography demands fast autofocus, telephoto lenses, and rapid continuous shooting.

While the FH22’s fixed 28-224mm (equiv) lens gives modest zoom reach, it lacks AF tracking and bursts beyond 5fps. The K-x’s 11-point hybrid AF and burst mode are on par, but the game changer is Pentax’s lens ecosystem, enabling pairing with telephoto primes and zooms up to 300mm and beyond for meaningful reach.

No surprise here: the K-x is the more capable wildlife choice.

Sports: Keeping Up with Action and Low Light Challenges

Sports shooting similarly benefits from fast continuous focus, high shutter speeds, and high ISO performance.

The K-x offers shutter speeds up to 1/6000s, faster than the FH22’s 1/1600s max, enabling better freezing of action. It also supports exposure compensation, aperture/shutter priority, and manual modes for nuanced exposure control. The FH22 is limited to fully automatic shooting with no manual aperture or shutter speed control.

The K-x’s better high ISO handling and larger buffer also give it the edge for indoor or dimly lit sports arenas.

Street Photography: Discretion, Agility, and Spontaneity

Street shooters generally prefer small, light, and discreet cameras.

The FH22’s compact size and silent shutter technology (though limited here) make it an unobtrusive partner for candid shooting. However, its slower AF and screen reliance for composition can be drawbacks.

The K-x, while bulkier and louder due to mirror slap, provides faster AF and more control but demands more commitment in setup and presence. Your choice here may hinge on personal shooting style.

Macro Photography: Magnification and Close-Focus Precision

The FH22 offers a minimum 5cm focusing distance, sufficient for casual macro snapshots but no specialized control.

Pentax lenses dedicated to macro work, combined with the K-x’s manual focus fine tuning, deliver far greater precision and image detail for serious close-up work.

Night and Astrophotography: Testing Noise and Exposure Control

The K-x supports ISO up to 12800 (boosted) and offers manual exposure modes - key for night or astro enthusiasts needing long exposures and high sensitivity without crippling noise.

The FH22 maxes at ISO 6400 native with modest noise control and no manual exposure or RAW support. Long shutter speeds are limited.

If you’re venturing seriously into nightscape or astrophotography, the K-x is clearly better poised.

Travel Photography: Versatility and Battery Endurance

Travelers often want a versatile all-rounder with good battery life.

The FH22 scores for size and weight, but at 170 shots battery life and modest low-light versatility, it can become a liability on extended trips.

The K-x balances versatility with hearty battery life (1900 shots), robust lens mount options, and better image quality, but at the cost of bulk.

Professional Workflows and File Formats

A significant professional advantage of the K-x is RAW file support - allowing non-destructive editing and precise control over every raw image parameter.

The FH22 offers only JPEG output, limiting flexibility. Additionally, the K-x supports exposure bracketing, custom white balance, and comprehensive exposure modes professional workflows demand.

Putting It All Together: Scores and Standouts

Looking beyond specs, here’s a visual summary of their strengths across key categories:
