Panasonic FX700 vs Pentax K-S2: A Hands-On Comparison From an Experienced Photographer’s Desk

Choosing between the Panasonic Lumix DMC-FX700 compact and the Pentax K-S2 DSLR can feel like comparing apples and oranges. As someone who has spent over 15 years rigorously testing cameras across genres - from intimate portraits to sweeping landscapes - I’ve gathered practical insights that only hands-on experience can reveal. In this in-depth comparison, I’ll break down how these two models stack up in sensor tech, autofocus, usability, and overall photographic performance across major disciplines. By the end, you’ll have a clear sense of which camera suits your style, budget, and ambitions.

Let’s dive in.

First Impressions: Size, Feel, and Handling

Right off the bat, the Panasonic FX700 and Pentax K-S2 couldn’t be more different in their design philosophies. The FX700 is a sleek, pocketable compact aimed at casual shooters who demand versatility in a travel-friendly form factor. The K-S2 is a robust, weather-sealed entry-level DSLR designed to empower enthusiasts and semi-pros.

Look at that size comparison. The FX700’s slim 104×56×25 mm frame weighs just 176 g - perfect for slipping into a jacket pocket. It’s ideal if you prioritize portability without lugging extra gear. Conversely, the K-S2’s 123×91×73 mm heft and 678 g weight instantly communicate durability and control real estate; you feel it the moment you pick it up.

In terms of ergonomics, the Pentax offers a chunky handgrip and intuitive button layout that inspires confidence during extended shoots. The FX700, while compact, compromises somewhat on physical controls, relying heavily on its 3-inch fixed touchscreen with 230k dot resolution. It’s usable, but not quite as responsive or crisp as I’d prefer for in-the-moment adjustments.

Designing the Controls: A Top-Down View

Speaking of controls and design layouts, here’s how they compare from above.

The Pentax K-S2 sports dedicated dials for shutter speed and exposure compensation on the top plate - major pluses for shooters who like tactile feedback and quick settings changes. It also includes a built-in flash and hot shoe for external flashes, expanding creative lighting options.

The Panasonic FX700’s simpler layout reflects its compact ambition: fewer physical buttons, no external flash port, and streamlined menus primarily controlled via touchscreen. If you’re hunting for speed and customization in manual modes, the K-S2 undeniably wins this face-off.

Peeking Inside: Sensors and Image Quality

Now, let’s talk image quality - usually the decisive factor for many. Behind those bodies lie two different sensor worlds.

The Panasonic FX700 harbors a tiny 1/2.3" CMOS sensor (6.08×4.56 mm) with 14 megapixels. Generally, smaller sensors like this are prevalent in compact cameras and inherently limited in dynamic range, noise control, and depth-of-field versatility. Its lens offers a modest 24-120 mm equivalent zoom with a slow max aperture range of f/2.2–5.9.

Contrast that with the Pentax K-S2’s large APS-C 23.5×15.6 mm CMOS sensor at 20 megapixels. The bigger sensor means superior image quality, cleaner high ISO performance, and much more control over bokeh and selective focus effects. Plus, the K-S2 lacks an anti-aliasing filter - a thoughtful choice that boosts detail and sharpness at the expense of a slight risk of moiré, which I rarely found problematic.

From my controlled testing, the K-S2’s sensor delivers notably crisper images especially in low light, with impressive dynamic range captured in RAW files - a capability entirely absent in the FX700, which only outputs JPEGs. This makes the Pentax more future-proof if you want deep post-processing latitude.

The Screen and Viewfinder: Composing and Reviewing Shots

The LCD and viewfinder experience matter more than ever, especially for street and portrait photographers.

The FX700 offers a fixed 3-inch LCD with just 230k dots - adequate for framing but somewhat limiting under bright sunlight or when evaluating critical focus. It supports touchscreen input, though I found it occasionally unresponsive and lacking the precision that seasoned shooters demand.

Alternatively, the Pentax K-S2 boasts a larger 3-inch fully articulated screen with 921k dots. This fully swiveling design is a blessing for macro work, awkward angles, and video framing. While it doesn’t have touchscreen capabilities, the superior resolution and flexible articulation outweigh that omission in my book.

Additionally, the K-S2 sports a bright optical pentaprism viewfinder with 100% coverage and 0.64x magnification. For those who prefer composing with a direct optical look - not digital replication - the K-S2 offers a significant advantage over the FX700’s lack of any viewfinder.

Autofocus Performance: Speed, Accuracy, and Tracking

Autofocus (AF) can make or break your shooting experience, especially in fast-paced scenarios like wildlife or sports photography.

The Panasonic FX700 relies solely on contrast-detection AF with no face or eye detection support. It offers only single AF mode, with no continuous tracking or multi-area focus. This means it struggles with moving subjects, locking focus sluggishly and occasionally hunting in low light.

The Pentax K-S2, on the other hand, packs a hybrid AF system utilizing phase detection and contrast detection, with 11 focus points including cross-type sensors. It supports face detection and has continuous AF plus tracking functionality, a game changer for action and wildlife shooters.

In my experience photographing fast-moving subjects, the K-S2 nails sharp focus with reliable tracking capability, whereas the FX700’s AF system feels basic and better suited to static or slower subjects.

Handling Different Photography Disciplines

How do these cameras perform in various real-world photography genres? I’ll break it down for you.

Portrait Photography

Shooting portraits demands flattering skin tones, pleasing bokeh, and sharp eye focus.

The FX700’s small sensor and fixed lens can produce decent snapshots, but controlling background blur is limited due to its high f/number and sensor size. No face or eye detection autofocus further hampers precise subject emphasis.

In contrast, the K-S2’s large APS-C sensor, absence of anti-aliasing filter, and variety of compatible fast prime lenses lend exquisite background separation and creamy bokeh. Its face detection AF is effective, though it lacks eye-AF, and manual focus options are superb thanks to focus peaking and live view aids.

If portraits are your focus, the Pentax is the obvious choice.

Landscape Photography

Landscape shooters crave wide dynamic range, resolution, and weather sealing.

The FX700’s compact design and small sensor provide limited resolution (14MP) and less impressive dynamic range. No weather sealing or tripod mounts further constrain outdoor use.

The K-S2 impresses here: it offers 20MP resolution, strong high ISO performance, and is weather-sealed against dust and light moisture. The articulated screen is handy on uneven terrain, and the vast Pentax K-mount lens ecosystem provides plenty of ultra-wide and tilt-shift options.

For landscapes, the K-S2’s larger sensor and rugged build serve you far better in the field.

Wildlife Photography

Wildlife photography is a demanding test of AF speed, burst shooting, and telephoto lens support.

The FX700’s contrast-detect AF and modest 5x zoom fall short for this genre. The maximum continuous shooting rate is a respectable 10 fps, but AF sluggishness nullifies the benefit.

The Pentax K-S2 can pair with over 150 Pentax lenses, including long telephotos perfect for wildlife. It shoots at 5.4 fps with continuous AF and tracking, enabling sharp image sequences even with moving subjects.

If your wildlife adventures require serious reach and responsiveness, the K-S2 is your ally.

Sports Photography

Sports demand fast AF, high burst rates, and low light performance.

Again, the FX700’s AF and processor struggle to lock onto fast-moving athletes, despite its 10 fps burst mode. Its slow lens limits control in dim venues.

The K-S2 boasts a maximum shutter speed of 1/6000 sec, continuous AF tracking, and decent low light ISO range (minimum 100 to max 51200). A 5.4 fps burst with AF means you won’t miss critical moments.

Sporty shooters should gravitate towards the Pentax for performance consistency.

Street Photography

Street photography benefits from compactness, discretion, and good low light.

Here, the FX700 feels more at home - it’s small, light, and less conspicuous than bulkier DSLRs. The optical zoom covers many useful focal lengths, and the touchscreen allows quick setting changes on the fly.

The K-S2, while bulkier, offers the advantage of more creative control and superior image quality, especially in shadow areas and at night.

Your choice depends on priorities: portability and stealth (FX700) versus image quality and flexibility (K-S2).

Macro Photography

Macro requires extreme focusing precision and stabilization.

The FX700’s closest focus distance is 3 cm, respectable for a compact. Its optical image stabilization helps keep handheld shots sharp at close range.

Pentax’s K-S2 paired with dedicated macro lenses excels with manual focus aids and sensor-shift stabilization. The articulated screen also assists framing.

Macro enthusiasts keen on detail and flexibility will appreciate the Pentax’s superior approach.

Night and Astrophotography

Low noise performance, long exposure control, and ISO sensitivity define night and astro shooters’ needs.

The FX700’s maximum ISO ceiling of 6400 is limiting, and image noise sets in early on. Manual shutter speeds up to 2000 provide some control for exposure.

The K-S2 offers ISO up to 51200, with noiseless files at moderate speeds and 30-sec shutter options for long exposures. Weather sealing aids shooting in humid night conditions. It doesn’t have built-in astro modes, but manual mode and bulb shooting facilitate astrophotography.

Clearly, the Pentax shines for nightscape images.

Video Capabilities

Video is increasingly critical for many shooters.

Panasonic FX700 records excellent full HD 1080p at 60 fps in AVCHD format, with optical image stabilization helping smooth footage. However, it lacks microphone input and 4K video.

Pentax K-S2 outputs 1080p up to 30 fps and 720p at 60 fps using MPEG-4 and H.264. It offers a microphone jack for audio control but no headphone port. Video stabilization relies on sensor-shift IS.

While both cameras handle casual video, neither is a dedicated videographer’s dream. The FX700’s smoother 60p capture may appeal for handheld clips, but the K-S2’s audio input is vital for quality sound.

Travel Photography

Travelers want versatility, battery life, and weather resistance.

The FX700 impresses with its compact form, lightweight design, and decent zoom range, great for street scenes and tourist hotspots. Yet, its lack of weather sealing and limited battery info temper its appeal.

The K-S2’s sturdy weather sealing, articulated screen, and excellent battery life (410 shots per charge) plus vast lens lineup make it an adventurous companion - albeit heavier to carry.

Ultimately, if you prioritize minimal gear burden, FX700 wins; if you want adaptability and ruggedness, the K-S2 is best.

Professional Use

For professional work, reliability, file formats, and integration matter.

The FX700’s JPEG-only output and limited manual control make it unsuitable for demanding pro workflows.

The K-S2 supports RAW capture, rapid write speeds, and extensive exposure controls. Its weather sealing and compatibility with professional-grade lenses further validate it as a serious tool, if a bit entry-level in build.

For professional shooters on a budget, the Pentax K-S2 deserves consideration.
