Panasonic Lumix GM5 vs Pentax ist DL2: A Deep-Dive into Two Distinct Cameras from Different Eras

When you place the Panasonic Lumix GM5 and the Pentax ist DL2 side by side, at first glance, it might feel like comparing apples and oranges - or better yet, a sleek spaceship and a trusty vintage sedan. These two cameras hail from wildly different times, technologies, and philosophies. Yet, for the discerning photographer, each offers lessons in design trade-offs, imaging strengths, and user experience.

Over my fifteen-plus years immersed in testing cameras across the spectrum - mountains and city streets, wildlife hideouts to portrait studios - I’ve developed a keen sense for what works and what doesn’t in real-world conditions. I’ve handled both these cameras hands-on and pitted them through rigorous evaluation protocols, from technical sensor charts to field shooting in diverse environments.

This comparison unpacks every facet - from sensor tech to ergonomics, autofocus to video, and beyond - to distill what you gain and give up by choosing one over the other.

Body Design and Ergonomics: Compact Chic vs Classic Bulk

Physically, these cameras couldn’t be more different. The Panasonic GM5, launched in 2014, epitomizes the minimalist, rangefinder-style mirrorless trend - small, sleek, and undeniably stylish. At just 99x60x36mm and a featherlight 211 grams, it fits like a glove in your palm or a deep pocket.

In contrast, the Pentax ist DL2, released back in 2006, is a traditional mid-sized DSLR with a solid, heftier body at 125x93x66mm and 565 grams. It has that prized DSLR heft that to some photographers screams durability and to others feels like lugging a brick.

Handling each side-by-side, the GM5’s compactness is a joy for street and travel photographers craving stealth and lightness. However, the limited grip area may challenge those with larger hands or heavy lenses. The ist DL2 offers a definite handhold advantage with its bulkier build and rubberized grips - ideal for longer sessions or rugged terrains - though at the cost of portability.

Neither camera boasts environmental sealing, so a rainstorm demands an umbrella or weather cover regardless of choice.

Control layouts reflect their eras and designs. The GM5 impresses with its top plate minimalist approach but doesn’t skimp on essentials - dedicated dials for shutter speed and exposure compensation, plus customizable function buttons. The touch-enabled 3-inch fixed LCD and electronic 1166-dot viewfinder (more on that shortly) evoke mirrorless modernity.

Pentax’s ist DL2 sticks to DSLR traditions - mode dial, a dedicated top LCD screen (albeit more modest), and a straightforward button system. No touch here; it’s all tactile, mechanical reassurance. The optical viewfinder with 95% coverage and 0.57x magnification has the clarity and immediacy fans of SLRs cherish.

Which camera is more comfortable? It depends on shooting style: the GM5’s rangefinder form excels when nimbleness and discretion matter, while the ist DL2 provides confidence and solidity when heft helps steady the hand.

Sensor Specs and Image Quality: Micro Four Thirds Precision vs APS-C Nostalgia

Now to the heart of the matter - image quality, and the sensor characteristics that define it. The Panasonic GM5 wields a 16MP Four Thirds CMOS sensor (17.3x13 mm) with a native ISO range of 200 to 25600, paired to Panasonic’s Venus engine processing. In contrast, the Pentax ist DL2 carries a 6MP APS-C CCD sensor (23.5x15.7 mm) with a native ISO range peaking at 3200.

At first glance, the Pentax’ larger sensor area (roughly 369mm² versus 225mm² for Panasonic) would seem a big advantage. Larger sensors typically mean better noise performance and dynamic range; however, evolving tech tells a deeper story. Here, the newer CMOS sensor in the GM5 benefits from better noise control, faster readout, and more sensitive circuitry despite the smaller physical size.

DxOMark scores make this clearer: Panasonic GM5 rates a combined overall score of 66, slightly edging the ist DL2’s 65. Digging into specifics reveals the Panasonic sensor boasts greater color depth (22.1 vs 22.9 bits close, so a slight edge to Pentax there) and a significantly better dynamic range (11.7 stops vs 11.1 stops), and most notably far superior low-light ISO performance (score of 721 vs 639).

In practical terms, the GM5 yields cleaner images under dim lighting conditions and pulls more nuance from highlights and shadows - key for landscapes and indoor portraiture where subtle tonality matters.

Pentax’s 6MP resolution feels limited today but maintains an analog charm with a CCD’s signature organic color response and smooth tonal gradations. Still, its narrow resolution caps crops or large prints.

The Fujifilm or Olympus sensors that followed redefined Micro Four Thirds, but the GM5 sensor is no slouch for its vintage and segment.

Lens Ecosystem

The Panasonic’s Micro Four Thirds mount opens access to an extensive lineup of over 100 MFT lenses, from ultra-sharp primes to versatile zooms, including many compact options ideal for travel and street shooters.

Pentax’s KAF mount offers a venerable range of 151 lenses, including legacy glass - valuable if you already own Pentax lenses or appreciate manual optics. However, many of these are bulkier and designed for APS-C DSLRs, meaning less portability.

Thus, Panasonic’s system feels better suited to the compact ethos of the GM5; Pentax plays to the DSLR user’s strengths with solid, heavier lenses.

Autofocus Performance: Speed vs Simplicity

The GM5's autofocus system is a hybrid contrast-detection type with 23 focus points, including face detection and touch AF capabilities. Unfortunately, it lacks phase detection pixels on sensor common in mirrorless rivals, but compensates with a refined algorithm for still subjects and moderately quick adjustments.

The Pentax ist DL2 sports a more archaic phase-detection autofocus system with only 5 points - no face or eye detection, no continuous tracking. This is reflective of its 2006 launch date when AF tech was still evolving.

In real shooting, I found the GM5 noticeably quicker and more reliable focusing on moving subjects, aided by face detection in portraits, especially in good light. The ist DL2 required more manual tweaking, focusing patience, and lacked the responsiveness sports or wildlife demands.

Neither camera matches modern beasts with eye-AF and sophisticated AF tracking, but Panasonic’s mirrorless tech is a clear step ahead - especially for travel, street, and portraits.

Handling Live View, Screens and Viewfinders: Electronic Evolution vs Optical Classic

The GM5 features a 3-inch, 921k-dot fixed touchscreen LCD and an electronic viewfinder (EVF) with 1166-dot resolution and 100% coverage. This EVF gives preview of exposure, white balance, and focus peaking - indispensable in today’s mirrorless workflow.

The Pentax ist DL2 sports a smaller 2.5-inch, 210k-dot fixed LCD without touchscreen (no live view, either) and a traditional optical pentaprism viewfinder. It provides a natural, lag-free view but with approx. 95% frame coverage and lower magnification, meaning you can’t see quite the whole scene in the frame.

The GM5’s EVF also allows viewing in bright sunlight when the LCD might wash out, an advantage for open-air shoots.

I personally love the tactile reassurance of a pentaprism OVF, but for critical framing, immediate exposure feedback, and manual focusing aids, the GM5 holds sway. Newbies especially find an EVF helpful for the constant feedback loop.

Burst Speed and Buffer: Who Can Keep Up?

If fast action thrills you, these numbers matter. The GM5 offers up to 5.8 frames per second (fps) continuous shooting, respectable for its segment and generation. In contrast, the older Pentax ist DL2 manages a more pedestrian 3.0 fps.

While neither camera is a sports-photography powerhouse, Panasonic’s faster rate eases capturing fleeting expressions and moments in wildlife or sports settings.

Moreover, buffer depth favors the GM5, handling longer bursts before slowing. The Pentax’s buffer can fill quickly especially when shooting RAW, pausing action sequences.

Video Capabilities: Panasonic Steals the Show

The Pentax ist DL2, being a pre-video DSLR, has no video recording at all.

The GM5 supports Full HD 1080p video recording at 60p, 60i, 50p, 50i, 25p, and 24p frame rates, encoded in AVCHD or MPEG-4. No 4K or high-speed modes here, but solid for casual videography. It lacks external microphone and headphone jacks, which limit advanced audio control.

Additionally, the GM5 includes time lapse recording, a nice creative tool missing on many entry-level rivals.

For filmmakers seeking HD footage with decent visual quality in a compact package, the GM5 holds an accessible edge.

Battery Life and Storage: Limited but Functional

The GM5’s official battery rating is about 220 shots per charge, which is on the low side but typical for mirrorless cameras with electronic viewfinders. Given its micro four-thirds format and small battery, expect to carry spares if shooting extended sessions - something former Olympus and Panasonic users know well.

The Pentax ist DL2’s battery life isn’t officially rated, but it uses standard 4x AA batteries, a boon for travel or fieldwork when recharge options are limited. AA batteries mean accessibility but also bulk and weight - trade-offs to consider.

Both cameras have a single SD card slot; the Pentax also supports MMC cards - a legacy medium at this stage.

Connectivity and Extras: What’s Under the Hood?

The GM5 surprises with built-in wireless connectivity and NFC, handy for quick image transfer and remote control from smartphones. It sports a full-size HDMI port and USB 2.0 - slow by today’s standards but functional.

The Pentax ist DL2 offers none of these modern feats - no wireless, no HDMI, and an outdated USB 1.0 interface. Reflective of its DSLR lineage and release date, it suits users who prioritize physical media and manual control over connectivity.

Both cameras lack weather sealing, image stabilization (sensor-shift or lens-based), and advanced exposure bracketing modes beyond the basics.

Image Samples Speak Louder Than Specs

Technicalities can only get us so far - how do these two cameras perform in the field visually?

Shooting portraits with the GM5 shows beautiful skin tone rendering, aided by a more neutral color profile and subtle noise handling. The shallow depth of field inherent to its Micro Four Thirds sensor and fast Panasonic lenses provides lovely bokeh - soft but not mushy, with smooth transitions.

The ist DL2’s colors have a warmer, vintage character, thanks to its CCD sensor and older image processing. Portraits feel reminiscent of film-era aesthetics but with more visible noise and lower resolution impacting detail sharpness.

For landscapes, GM5’s higher resolution and dynamic range come alive, capturing detail in shadows and highlights superbly. The Pentax holds up well in good light but struggles to hold highlight detail or recover shadows without noise creeping in, common to early CCD sensors.

In wildlife or sports sequences, the Panasonic’s faster AF and burst wins hands down for keeper rate and focus accuracy.

Night or astro photography? The GM5’s higher ISO tolerance and lower noise enable more usable shots without resorting to heavy noise reduction that blurs stars or details. The Pentax is more limiting here.
