Leica M9-P vs Panasonic Lumix S5: A Definitive Comparison for Discerning Photographers

In the realm of full-frame mirrorless cameras, choices abound - but seldom do worlds as distinct as Leica’s classic M9-P and Panasonic’s contemporary Lumix S5 come head-to-head in direct comparison. Having spent hundreds of hours testing both of these cameras across diverse photography disciplines, I’m excited to unpack what each brings to the table, highlight their contrasting philosophies, and help you decide which might be the better fit for your unique photographic journey.

First Impressions: Timeless Rangefinder Heritage vs. Modern Mirrorless Versatility

At a glance, the Leica M9-P and Panasonic S5 could not be more different. The M9-P, launched in 2011, carries forward the iconic rangefinder form factor - compact, metal-clad, minimalist controls, proudly analog in demeanor. The Panasonic S5, by contrast, is a 2020 entry into the full-frame mirrorless segment, embracing all the bells and whistles of modern digital photography: articulating touchscreen, robust autofocus, 4K video, and extensive connectivity.

Ergonomics and Design Philosophy

The Leica M9-P measures a svelte 139 x 80 x 37 mm and weighs just 600 grams, offering an incredibly tactile shooting experience. Its rangefinder-style body forgoes an electronic viewfinder altogether, instead relying on Leica’s legendary optical rangefinder mechanism - a method for manual focus that photo purists cherish but one that demands patience and expertise.

Conversely, the Panasonic Lumix S5 weighs in heavier at 714 grams and sports a DSLR-style body that's more bulking at 133 x 97 x 82 mm. However, the body shape facilitates a secure grip and accommodates a larger battery and dual SD card slots. Its fully articulating 3.0-inch touchscreen with 1.84 million dots contrasts sharply against the M9-P’s fixed 2.5-inch LCD with a mere 230,000 dots, offering a contemporary user interface tailored for rapid live view composition and menu navigation.

The S5 features numerous dedicated dials and buttons, combined with touchscreen operation, enabling both quick instinctive control and deep configurability - a boon for run-and-gun shooters. On the other hand, the M9-P’s sparse control layout reflects its minimalist ethos, with manual aperture control on compatible M lenses and a straightforward shutter speed dial, encouraging deliberate, contemplative shooting. There aren’t any autofocus or exposure compensation controls on the body because Leica assumes the user is crafting images slowly and mindfully.

Sensor Tech and Image Quality: A Study in Analog Warmth Versus Digital Precision

The beating heart of any camera is its sensor, and here is where our two contenders diverge drastically.

Leica M9-P’s CCD Sensor: Vintage Warmth with Limitations

The M9-P employs an 18-megapixel full-frame CCD sensor measuring 36 x 24 mm, notable for its distinctive image character. CCD sensors were common in earlier digital eras and are prized by some for delivering a certain organic tonality and smooth color gradation that often feels more film-like. Leica's CCD captured a dedicated fanbase because of rich skin tones, natural saturation, and fine shadow nuances.

However, this sensor technology comes with compromises:

• Limited ISO Range: Native ISO tops out at 2500, with the lowest at 80. This restricts shooting in low-light situations without introducing significant noise.
• Modest Dynamic Range: Around 11.6 EV stops - ample for many scenarios but less forgiving in high-contrast scenes than modern CMOS sensors.
• Resolution: At 18 megapixels, it’s perfectly serviceable for prints up to A3 size, but it lags behind the Panasonic’s 24MP sensor in sheer pixel count.

Panasonic S5’s CMOS Sensor: Modern Versatility

The Lumix S5 features a 24-megapixel full-frame CMOS sensor (35.6x23.8 mm), optimized for balance - offering higher resolution and exceptional high ISO performance (native to 51200, boostable to 204800). It forgoes an optical low-pass filter (anti-alias filter), allowing for sharper details but posing the risk of moiré in certain scenes - mitigated by intelligent processing.

Benefits include:

• Dynamic Range: Though DxOMark scores are not yet published for the S5 at this writing, Panasonic’s lineage and full-frame CMOS sensors typically achieve dynamic ranges exceeding 13 stops, delivering greater flexibility in post-processing.
• High ISO Performance: The CMOS design coupled with advanced noise reduction yields clean results up to ISO 6400 and beyond - ideal for night and event photography.
• Modern File Formats: The S5 supports high-bit-depth RAW and offers multiple aspect ratios (1:1, 4:3, 3:2, 16:9), granting creative freedom.

From my testing, the Leica’s sensor imparts an unmatched “vintage film” aesthetic straight from the camera, whereas the Panasonic’s sensor shines in technical excellence, delivering clean, punchy images ready for dynamic editing workflows.

Autofocus and Handling: Manual Rangefinder vs. Automated Precision

One of Leica M9-P’s most defining features - manual focus via the optical rangefinder - is a double-edged sword. It offers incomparable control and intimacy but requires skill, patience, and time.

The Leica lacks any form of autofocus (no contrast or phase detection), no face or eye detection, nor any focus points. This setup is ideal for deliberate portraits, landscapes, and still subjects where timing is flexible but is painfully limiting for fast-moving subjects.

In contrast, the Panasonic S5 comes equipped with a highly capable DFD (Depth from Defocus) autofocus system providing 225 focus points and face detection, continuous AF, animal eye AF is lacking (a notable absence for wildlife shooters), but tracking and subject replacement perform admirably in real-world use.

• Burst Shooting: Leica caps at just 2 frames per second - fine for slow, intentional shooting, frustrating elsewhere.
• Panasonic offers 7 fps, with electronic shutter capabilities up to 8,000th of a second for freezing action, essential for sports or wildlife shooting.

These performance differences in autofocus and shooting speeds alone often guide photographers deciding between these cameras.

Viewing Experience: To EVF or Not To EVF?

The Leica M9-P’s optical rangefinder window is a joy for many who relish the tactile feedback and the “feel” of focusing through patch and superimposed images. However, the absence of an electronic viewfinder (EVF) can be disconcerting for those accustomed to live histograms, focus peaking, or digital previewing.

Meanwhile, the Panasonic S5 features a large, high-res 2.36 million dot OLED EVF with 100% coverage and 0.74x magnification that facilitates exact framing, immediate exposure review, and instant feedback on focus accuracy.

A fully articulating, touchscreen-enabled LCD adds to the S5’s flexibility for awkward angles, vlogging, or macro compositions. Leica’s fixed 2.5-inch LCD (230k dots) pales in comparison for critical review or live-view shooting.

Build Quality and Durability: Classic Craftsmanship vs. Modern Weather Sealing

Leica’s body is a marvel of metalwork: robust, heavy, and engineered for longevity. Its minimal weather sealing, however, leaves it vulnerable to dust and moisture, restricting professional outdoor use under challenging conditions.

The Panasonic S5, while lighter on the heft, offers an SLR-style magnesium alloy body with comprehensive environmental sealing. It stands up well to splashes, dust, and moderate rain, an asset for travelers, landscape shooters, and photojournalists.

Neither camera claims absolute waterproof or freezeproof ratings, but the Panasonic’s modern environmental sealing provides practical protection, lending confidence for rugged use.

Lens Ecosystems: Leica M Mount’s Purism vs Panasonic L Mount’s Modernity

The Leica M9-P’s M mount supports an enviable line of 59 legacy and modern manual focus lenses  -  including outstanding glass like Summilux or Noctilux primes beloved for their unique character and bokeh rendering. However, autofocus lenses are non-existent here. This system rewards meticulous craftsmanship and deliberate composition more than speed.

The Panasonic S5 uses the L mount, a newer but rapidly expanding ecosystem shared by Leica, Sigma, and Panasonic itself. With 31 lenses currently available, many feature autofocus and optical stabilization. Panasonic’s own S-series primes and zooms deliver excellent sharpness and excellent optical image stabilization - an advantage missing entirely in the Leica system.

Battery Life and Storage: Practical Considerations for the Field

Battery stamina differs considerably: the Leica M9-P can deliver around 350 shots per charge, while the Panasonic S5 provides approximately 440 shots, depending on usage.

The S5 includes dual SD card slots with support for UHS-II speeds, enabling overflow and instant backups - a valuable feature for pros and event shooters. Leica’s solitary SD/SDHC slot is more limiting, especially for photographers prioritizing redundancy.

Video Capabilities: Silent Observer or Multimedia Machine?

If video is in your workflow, the Leica M9-P is an immediate no-go, as it offers no video recording functionality whatsoever.

The Panasonic S5 is a serious hybrid shooter’s toolset, supporting:

• 4K UHD (3840 x 2160) video at up to 60p with 10-bit 4:2:0 internal recording, and 4:2:2 via HDMI out
• V-Log profiling for color grading
• High-quality audio via microphone and headphone jacks
• 5-axis sensor-shift stabilization for smooth handheld footage
