Leica M Typ 240 vs Panasonic Lumix GX7: A Hands-on Camera Comparison for Today's Discerning Photographer

Choosing between two very different mirrorless cameras can feel like navigating two worlds at once. On one hand, the Leica M Typ 240 represents a legacy of rangefinder craftsmanship paired with modern full-frame imaging. On the other, the Panasonic Lumix GX7 embraces Micro Four Thirds versatility with advanced electronic features and compact portability. Both launched within a year of each other - 2012 and 2013 respectively - they still attract photographers seeking a distinctive shooting experience. Over my 15+ years of camera testing, I’ve put these two through extensive real-world and technical trials to share an authoritative, practical comparison you won’t find elsewhere.

In this deep dive, we’ll explore how these cameras perform across a range of photographic genres - from landscapes to wildlife, portraits to videos - while dissecting sensor tech, ergonomics, autofocus intricacies, and more. No marketing fluff, just honest, evidence-based insights based on hands-on testing with both bodies and dozens of lenses. I’ll also highlight which user types stand to gain the most from each system, considering price-to-performance ratios and the broader ecosystem.

Let’s start by putting the cameras in perspective with a look at their size and ergonomics.

Physical Feel and Handling: The First Impression Counts

The Leica M Typ 240 commands attention with its substantial, minimalist construction made of solid brass and magnesium alloy, weighing in at 680 grams with dimensions of 139 x 80 x 42 mm. It firmly embraces the classic rangefinder aesthetic - simple top plate dials, a manual focus lens mount, and no auto-focus components. Handling the M Typ 240 feels like holding history in your hands. Its heft and build quality scream luxury and purpose but lack some modern ergonomic conveniences, like a tilting or touch screen.

Contrast that with the Panasonic GX7, which weighs a nimble 402 grams and measures 123 x 71 x 55 mm. The GX7’s body is more diminutive, yet pleasantly solid with textured grip accents and a modern design language. It features a tilting 3-inch touchscreen with higher resolution and a pop-up electronic viewfinder (EVF) with a crisp 2.7M-dot OLED panel. This makes it more adaptable to various shooting angles, especially street or macro photography.

From lived experience, if you prioritize classical handling and tactile manual control - turning the aperture ring directly on the lens, setting ISO via physical dials - the M Typ 240 impresses. Meanwhile, the GX7’s ergonomics position it as a handy, everyday carry camera more suited for hands-on digital operation and quick settings changes.

The control layout further illustrates their design philosophies. The Leica eschews illuminated buttons and status screens on top, whereas the GX7 includes a top crystal display for shooting info and ergonomic dials for shutter speed, exposure compensation, and ISO - all programmable and backlit. For photographers shooting under challenging lighting or fast-moving conditions, the GX7’s interface is the more practical choice.

Sensor and Image Quality - The Heart of the Camera

At the core, the Leica M Typ 240 houses a 24MP full-frame CMOS sensor (36x24 mm) with an anti-aliasing filter, yielding large pixel pitches conducive to exquisite image quality and dynamic range. This sensor achieved an 84 DxO Mark overall score, with excellent 24-bit color depth and a wide 13.3-stop dynamic range that aids in recovering shadow and highlight detail.

The Panasonic GX7, in contrast, sports a 16MP Micro Four Thirds sensor (17.3x13 mm), roughly 1/4 the surface area of Leica’s full-frame. It scored a respectable 70 DxO Mark overall, including decent 22.6-bit color depth and a good - but more limited - 12.2-stop dynamic range. Its native ISO ranges from 125 to 25600, offering flexibility albeit with expected elevated high-ISO noise compared to full-frame sensors.

Let’s look closer:

• Color Depth: Leica’s sensor delivers richer gradations, essential for portrait skin tones and landscapes demanding nuanced color transitions.
• Dynamic Range: The M Typ 240’s 13.3 stops allow retaining details in bright skies and deep shadows, which is crucial for landscape and high-contrast environments.
• Low-Light Performance: Leica’s sensor holds up impressively to ISO 6400, with usable images and less aggressive noise reduction. The GX7 performs well up to ISO 1600–3200 but struggles beyond that, showing visible grain and detail loss.

In practical side-by-side testing, portraits from the Leica exhibit creamy, natural skin tones with smooth bokeh due to the use of Leica M-mount prime lenses with wide apertures. Meanwhile, the GX7’s smaller sensor and Four Thirds lens system produce shallower depth of field but with less pronounced subject separation.

Autofocus Systems: Precision vs Speed

One of the most stark differences is autofocus capability. Leica’s M Typ 240 is a purely manual focus camera relying on a traditional optical rangefinder mechanism. There is no autofocus built into the body or lenses. This requires deliberate focusing techniques such as zone focusing or focusing with manual lenses, making it a favorite among fine art photographers or those valuing precision over speed.

The GX7, however, features a hybrid autofocus system with contrast-detection AF (no phase detection) across 23 focus points and face detection built-in. It supports continuous AF (AF-C), single AF (AF-S), tracking, center, and multi-area modes, and a responsive touchscreen AF managment.

In wildlife or sports photography, the Leica is impractical unless you deploy skilled zone focusing or pre-focus, which limits burst performance. The GX7 shines here with 5 fps continuous shooting and reliable AF tracking of steady subjects in good light. The autofocus is snappy in daylight but not exceptional in dimmer environments, as expected for an older Micro Four Thirds contrast-only system.

Build Quality and Weatherproofing - Taking the Cameras Outdoors

Leica equips the M Typ 240 with partial environmental sealing, designed to withstand some moisture and dust - though not fully waterproof or freezeproof. Its all-metal body exudes durability for professional use, yet the absence of in-body image stabilization or weather-buffering touches may demand extra caution in harsh shoot conditions.

In comparison, the Panasonic GX7 lacks official weather sealing, with a plastic-magnesium composite body designed more for urban and travel photographers seeking lightweight versatility rather than rugged terrain resilience.

Displays and Viewfinders - Modern Versus Classic Compositions

The Leica M Typ 240 forgoes an LCD touchscreen in favor of a fixed 3-inch 920K-dot TFT LCD and an optical rangefinder viewfinder (0.68x magnification, 100% coverage). This demands a manual focusing workflow and composition intuition. Some photographers find shooting with the rangefinder's framelines and parallax error charming; others crave the digital convenience lacking here.

The GX7’s tilting 3-inch 1.04M-dot LCD with touch control complements its 100% coverage electronic viewfinder offering 2.76 million dots at 0.7x magnification. This EVF provides live exposure preview, focus peaking, and other digital aids invaluable for quick framing, especially in street and video work.

Lens Ecosystem: Investment in Glass

A big part of the Leica M system’s allure is the availability of over 50 native Leica M lenses, renowned for their optical quality and character, many dating back decades. These lenses are manual focus, mechanical wonders prized in portrait, street, and documentary photography. Leica lenses come with premium price tags and are generally prime optics without zooms.

The Panasonic GX7 uses the Micro Four Thirds mount, supported by more than 100 lenses from Panasonic, Olympus, and third parties. This ecosystem includes affordable and fast primes, versatile zooms, and specialized macro or telephoto lenses. Autofocus is handled electronically and smoothly, expanding creative flexibility.

The significantly smaller sensor size also impacts lens selection: a 25mm prime on Leica is effectively 25mm, while on Panasonic Micro Four Thirds, the 12.5mm lens approximates that field of view due to the 2.1x crop factor.

Battery Life and Storage Convenience

Leica’s M Typ 240 boasts about 500 shots per charge, slightly better than average for mirrorless cameras of its era, reflecting efficient processing and lack of power-hungry AF or EVF systems.

The GX7 offers approximately 350 shots per charge, which is reasonable considering electronic viewfinder usage and sensor stabilization.

Both use single SD card slots compatible with SDHC and SDXC formats.

Connectivity and Miscellaneous Features

Leica sticks to USB 2.0 and omits Wi-Fi, Bluetooth, or HDMI ports out of the box - streamlining the experience but limiting image transfer versatility.

Panasonic adds built-in wireless connectivity with NFC but lacks Bluetooth. It offers full HDMI output for external monitoring and integrates timelapse recording and a built-in flash, features absent on the Leica.
