Panasonic FX90 vs Pentax ist DL2: A Deep Dive into Two Cameras from Different Worlds

In the ever-evolving universe of photography gear, it’s fascinating to pit two cameras against each other that come from vastly different philosophies, eras, and user priorities. Enter the Panasonic Lumix DMC-FX90 - a compact camera born in the era of the smartphone encroachment (2011), versus the Pentax ist DL2, an early digital single-lens reflex (DSLR) from 2006, representing the more traditionalist approach to photography: manual controls, interchangeable lenses, and APS-C sensors.

At first glance, this comparison almost feels like comparing apples to tractors - small sensor point-and-shoot versus mid-size DSLR. But for enthusiasts and pros curious about what these cameras delivered in their prime (and what lessons remain relevant today), this detailed, hands-on comparison aims to illuminate both their strengths and shortcomings across all key photographic disciplines.

Getting Hands On: Size and Ergonomics Matter - Especially in Real Use

First impressions count. And one of the easiest ways to grasp that? Simply holding the cameras.

The Panasonic FX90 weighs a featherlight 149 grams and fits snugly in the hand and pockets alike (102x56x22mm). It screams travel-friendly and street-ready - no fuss, no heavy gear bag, just slide it in and shoot. The grip is minimal but sufficient, given the reduced bulk. The fixed lens means you’re never needing to fiddle with changing glass, which translates to speed and simplicity in the moment.

Contrast that with the Pentax ist DL2’s hefty 565 grams and substantial dimensions (125x93x66mm). This SLR heft means serious handling, and honest to me, it feels like a camera you mean business with - subtle desk companion or bulky travel suitcase filler it is not. The deeper grip, large physical controls, and solid build all add to that professional presence.

Ergonomically, the DSLR’s size means greater comfort during long shoots, and a strong sense of camera balance once you get your preferred lens mounted. The FX90, while pocketable, compromises on manual control placement and feels fragile by comparison.

Still, for walkaround portability and stealthy street photography, the Panasonic shines.

Cockpit Views: Control Layouts and Handling Nuances

Taking a peek at their top decks reveals much about who Panasonic and Pentax thought would hold these cameras.

The FX90’s control suite is minimalist - an approachable interface aimed at quick point-and-shoot use. There’s a mode dial, but no dedicated buttons for shutter speed or aperture priority because, well, they don’t exist. Instead, you get a touchscreen that handles menus and autofocus spot selection. For rapid casual shooting, this simplifies operations - but it restricts creative input.

The Pentax ist DL2, meanwhile, keeps true to DSLR traditions. Physical buttons and dials give immediate access to shutter speed, aperture, exposure compensation, and shooting mode. As a long-time DSLR user myself, I appreciate how quickly I can dial in specific settings without diving into menus - this tactile control breeds confidence especially under fast-paced demands like sports or wildlife photography.

The DSLR’s optical viewfinder (OVF) offers a critical advantage in bright light - an advantage the FX90’s lack of any viewfinder cannot match; composing on an LCD screen in daylight can be challenging.

So, if you prize direct access and physical dials, the Pentax is your camera. If fingers-up simplicity and lightweight design are your jam, Panasonic delivers.

The Heart of the Matter: Sensor Size, Resolution, and Image Quality

Here’s where the two diverge dramatically - sensor technology and performance.

The FX90 uses a 1/2.3” CCD sensor measuring just 6.08x4.56mm, with 12 megapixels delivering a maximum image size of 4000x3000 pixels. The Pentax ist DL2 features a much larger APS-C sized CCD sensor at 23.5x15.7mm (approximately 369 mm²), but with a much lower resolution of 6 megapixels (3008x2008 pixels).

I should note from long, careful testing across hundreds of CCDs and CMOS sensors that larger sensors inherently gather more light and produce less noise, resulting in better dynamic range and low-light performance. Smaller compact sensors, like in the FX90, tend to struggle in dim conditions and offer less tonal gradation.

In practice, the Pentax delivers significantly better color depth - confirmed by DxOMark’s color depth score of 22.9 bits versus Panasonic’s no published data for the FX90, but generally lower on such small sensors. The Pentax’s dynamic range of 11.1 stops holds more detail in shadows and highlights compared with what we’d expect from small-sensor compacts. Meanwhile, the Panasonic’s maximum ISO 6400 boosts are often too noisy for clean usable shots.

The Pentax’s support for RAW files is a huge bonus for post-processing flexibility - the FX90 does not offer RAW, restricting edits to JPEGs and limiting the ability to recover highlights or shadows.

In landscape and portraiture - where image quality reigns supreme - the ist DL2 wins outright for richer details and superior tonal range.

Looking Back: Screens and User Interface in Practice

When shooting handheld, the rear LCD is your window to composition and review.

The FX90’s 3” touchscreen LCD with 460k dots offers good resolution and intuitive control - pinch to zoom, tap to focus - all very modern for 2011 standards. It’s fixed type, meaning no tilting, but still bright enough for street or indoor shooting.

The ist DL2’s slightly smaller 2.5" screen with 210k pixels feels dated and coarse, especially when reviewing fine details, but it’s typical for cameras of its release period. More importantly, the lack of live view or touchscreen means composing on-screen is less flexible and user-friendly.

Hence, for casual shooting, the FX90’s interface is clearly friendlier. For critical compositions and manual adjustments though, the Pentax’s physical controls and OVF outweigh screen sharpness.

Autofocus and Shooting Speed: Tracking Your Subject in Real Time

Let me dig into autofocus performance, which hugely impacts usability across portrait, wildlife, and sports photography.

The FX90 offers contrastedetection AF with 23 focus points, plus some face detection capabilities (though no eye or animal eye detection). Contrast AF systems, especially in older compacts, tend to be slower and prone to focus hunting, especially in low light or low contrast scenes. Panasonic's inclusion of continuous autofocus and tracking is nice, but in my tests, the FX90’s AF occasionally struggled with moving subjects, leading to missed shots.

The Pentax ist DL2 uses a phase detection AF system with 5 focus points, including selective and multi-area autofocus options. Phase detection AF, while limited to fewer points, delivers much faster focus lock and superior tracking of moving subjects - invaluable for wildlife and sports applications. While 5 points on the Pentax feel restrictive by modern standards, for 2006 tech this was respectable; that said, the Pentax has no face or eye detection, so portrait shooting requires a bit more skill and patience to nail focus.

Burst shooting rates are roughly similar: Panasonic FX90 at 4 fps and Pentax ist DL2 at 3 fps - decent but far from sports action cameras. Also, the DSLR’s traditional shutter mechanism offers more creative shutter speeds and priority modes (shutter, aperture), whereas the FX90 limits you to automated exposure.

Zoom Lenses vs Interchangeables: What Does Your Lens Playground Look Like?

One of the fundamental divides here is the lens system.

The Panasonic FX90 sports a fixed 24-120mm equivalent zoom lens with a max aperture of f/2.5-5.9. This range covers wide to medium telephoto useful for almost everything casual - landscapes, portraits, street. The fast wide aperture (f/2.5) at 24mm allows for some decent low-light shooting and bokeh, but the narrower maximum aperture at telephoto end (f/5.9) limits background blur and autofocus speed in dimmer conditions.

The Pentax ist DL2 accepts Pentax K-mount lenses, with over 150 compatible options - everything from ultra-wides to specialty macros and fast primes. This system flexibility means you can pick the ideal lens for each discipline - a monster telephoto for wildlife, a 50mm f/1.4 for portraits, or a macro lens for close-ups. The ist DL2's APS-C sensor also benefits from the superior optics of prime lenses, giving sharper results and more creative depth of field control.

In my experience, this freedom to adapt optics ensures the Pentax outperforms the FX90 in nearly every photographic niche bar strict portability.

Diving Into Photography Genres: Who Excels Where?

Let’s tune into key photography styles, assessing which camera you might want tagging along.

Portrait Photography

Skin tone rendition crucially relies on sensor color depth and lens characteristics. The Pentax’s APS-C sensor and lens mount ease allow you to craft creamy bokeh and natural skin tones, especially with prime lenses. Eye detection isn’t available on either - you’ll rely on manual focus precision or face detection on the FX90, which is basic at best.

The FX90’s limited aperture zoom and JPEG-only workflow limit creative expression but suffice for casual portraiture.

Landscape Photography

Dynamic range and resolution matter most here.

The Pentax ist DL2’s APS-C sensor offers more dynamic range (~11 stops), allowing for fine detail retrieval in shadows and highlights. The 6MP resolution suits web use or 8x12 prints well; not ultra-high-res but respectable for the era’s DSLRs.

The FX90’s 12MP sensor supplies higher resolution, but the small sensor’s limited dynamic range and noise at higher ISOs reduce final image quality. Also, the lack of weather sealing in both cameras advises caution in harsh conditions.

Wildlife and Sports Photography

Fast autofocus, quick burst shooting, and long focal lengths are paramount.

While the Pentax’s lens system lets you equip telephoto superzooms or prime lenses to reach distant subjects, the FX90 maxes out at 120mm equivalent - modest telephoto at best.

Autofocus tracking on the Pentax, despite just 5 points, works better on moving subjects due to phase detection tech.

Street Photography

Here, discretion and portability rule.

The FX90’s tiny size, quick startup, and silent operation are huge pluses for candid shots. The Pentax is louder, bigger, and more conspicuous.

Macro Photography

The FX90 offers a 3cm macro focusing distance, respectable for a compact. The Pentax, when fitted with dedicated macro lenses, can lean heavily into precision and magnification.

Night and Astro Photography

High ISO noise performance hurts the FX90 with its tiny sensor at above ISO 800 - grain often dominates. The Pentax, with lower max ISO (3200) and less aggressive noise handling, delivers cleaner results due to larger pixels and better sensor quality.

Neither support long exposure modes built-in, but the Pentax’s manual settings give more control for astro shots.

Video Capabilities

The FX90 supports 1080p HD video at 60fps, a notable feature back in 2011. MPEG-4 and AVCHD codecs are inclusionary but without microphone input or 4K. The Pentax ist DL2 doesn’t offer video recording at all.

Travel Photography

The FX90’s size, light weight, and 5x zoom make it a gentle companion. Battery life is limited (~200 shots), though. The Pentax’s bulk and the need to carry lenses weigh travel down but reward with image quality and versatility.

Professional Workflows

Pentax wins with RAW output, manual exposure modes, and lens options. Both cameras lack environmental sealing common in professional bodies today.

Build Quality, Weatherproofing, and Longevity

Neither model sports environmental sealing, nor ruggedized builds. The Pentax ist DL2’s robust DSLR chassis offers more physical protection than the plastic-bodied FX90.

Battery types differ greatly: FX90 uses proprietary packs, Pentax accepts easily sourced AA batteries - which can be an advantage in travel emergencies.

Connectivity and Features: Staying Connected in 2024?

The Panasonic FX90 includes built-in wireless connectivity (Wi-Fi), USB 2.0, and HDMI out - quite forward-thinking for 2011. No Bluetooth or NFC.

Pentax ist DL2 has basic USB 1.0 port, no wireless features, and no video output.

Value and Price: What You Get for Your Money

The FX90’s street price hovers around $227 - cheap for a stylish, pocketable compact. The ist DL2 is now a discontinued vintage DSLR with no standard pricing on the market, but when new was a mid-tier entry-level DSLR.

Used Pentax models can be found affordably, but to fully benefit, your budget should include lenses.

The Final Tally: Ratings and Recommendations Based on Genre

After rigorous tests - from focusing on color accuracy, shooting speed, to handling ease - here’s an overview that sums up their genre-specific prowess.

The Pentax ist DL2 excels primarily in portrait, landscape, and professional workflows, aided by superior sensor size, RAW shooting, and lens ecosystem. The Panasonic FX90, with its portability and video capabilities, makes a solid choice for street, travel, and casual video shooters.

Seeing Is Believing: Sample Images from Both Cameras

Let’s look at real-world shots illustrating these points.

Notice the Pentax’s smoother tonal transitions and better shadow retention, while the Panasonic images tend to be punchier but harsher in contrast and noise.

Wrapping It Up: Which Camera Should You Choose?

If you crave simplicity, superb portability, and decent HD video in one slim package, the Panasonic FX90 is a capable mini-workhorse - especially for casual and travel use.

If image quality, manual control, and system expandability matter more - particularly for portrait, landscape, or anything professional - the Pentax ist DL2, despite its age, still holds ground as a photographer’s companion, provided you supplement it with lenses.

Either way, you’re looking at cameras that teach fundamental lessons about sensor size trade-offs, control ergonomics, and the evolution of autofocus and video features in digital camera history.

For today’s buyers, I’d suggest considering these as archival or entry points into particular shooting styles, and using their strengths to appreciate how far camera tech has come.

Happy shooting - whatever gear you trust to capture your vision!
