Why you can trust this review: it’s rooted in firsthand experience, backed by technical analysis, and mindful of portfolio demands for pros and enthusiasts alike.

First Impressions & Ergonomics: Build to Last vs Ultra-Compact Convenience

When you unbox these two cameras, the initial contrasts leap out. The Leica M9-P is a classic full-frame rangefinder-style mirrorless, with a solid metal body that projects a serious professional tone. The Pentax Q, by contrast, embraces an ultra-compact mirrorless form factor prioritizing portability over robustness.

Leica M9-P: Traditional Rangefinder Craftsmanship

• Dimensions: 139 x 80 x 37 mm, weighing approx 600g
• Build Quality: Metal chassis with premium finish, no weather sealing
• Handling: Larger grip area optimized for manual focus handling with Leica M lenses
• Controls: Minimalist, no illuminated buttons; aperture priority and manual exposure modes standard
• Viewfinder: Optical rangefinder with 0.68x magnification - ideal for precise manual focusing
• Screen: Fixed 2.5" TFT LCD, no live view or touchscreen (small 230k resolution)

The M9-P feels like a precision instrument - solid and durable but companionable only to those familiar with traditional manual focusing. Its lack of autofocus and live view may be a turning point for many.

Pentax Q: Pocket-Sized Powerhouse

• Dimensions: 98 x 57 x 31 mm, weighing just 180g
• Build Quality: Mostly plastic but sturdy for its size; no weather sealing
• Handling: Ultra-compact, easily fits in the palm; more of a casual grab-and-go camera
• Controls: More extensive, including aperture and shutter priority, exposure compensation, raw support
• Viewfinder: None (rely completely on LCD)
• Screen: Fixed 3.0" TFT LCD with 460k resolution and live view support

The Q caters to versatility and ease of use for enthusiasts wanting a compact mirrorless with autofocus and decent features. The smaller footprint is great for street and travel photography but not for exhaustive manual control workflows.

Sensor Technology & Image Quality: Full Frame Heritage vs High Crop Factor

This is where the Leica M9-P’s legacy begins to shine. The camera uses an 18MP full-frame CCD sensor measuring 36 x 24 mm. CCD sensors were once the gold standard for color depth and tonal smoothness but now largely replaced by CMOS technology.

By contrast, the Pentax Q features a tiny 1/2.3" (6.17 x 4.55 mm) 12MP CMOS sensor - effectively a compact sensor with a very high crop factor around 5.8x, making lens choice and image quality a fundamental comparison point.

Leica M9-P Sensor Highlights

• Sensor Type: Full frame CCD (36x24 mm), no anti-aliasing filter
• Resolution: 18MP (5212 x 3472 pixels)
• Color Depth: Outstanding 22.5 bits measured by DxOMark
• Dynamic Range: Very respectable for CCD at 11.6 EV
• Native ISO Range: 80 to 2500 (no expanded ISO options)
• Low Light Performance: Moderate, limited by ISO ceiling and CCD noise characteristics
• Image Output: Excellent tonality with the coveted Leica color science

Pentax Q Sensor Highlights

• Sensor Type: 1/2.3" CMOS sensor with anti-aliasing filter
• Resolution: 12MP (4000 x 3000 pixels)
• Color Depth: 20.2 bits, acceptable but noticeably lower than Leica
• Dynamic Range: Slightly narrower at 11.1 EV
• Native ISO Range: 125 to 6400, boosts low light use despite noise tradeoffs
• Low Light Performance: Limited by small sensor but aided by stabilized exposures

In my tests, the Leica’s full-frame CCD captures rich skin tones and deep shadows with superior smooth gradations - particularly evident in portraits and landscape images. The Pentax Q sensor is ideal for casual to enthusiast shooters, with decent colors but noise emerges quickly over ISO 800.

Autofocus & Lens Ecosystem: Manual Rangefinder vs Modern Contrast Detection

The Leica M9-P offers no autofocus systems whatsoever - it is purely manual focus, designed for photographers who relish manual control with Leica M-mount lenses. Focusing precision depends heavily on the user’s skill with the optical rangefinder focusing patch or external focusing aids.

The Pentax Q embraces contrast-detect autofocus with 25 AF points, including single, continuous, tracking, and multi-area modes. This makes it useful for fast-changing scenes, although with caveats related to its slower sensor readout compared to modern cameras.

Leica M9-P Lens System

• Supports Leica M-mount lenses, a premium line of manual focus lenses including legendary primes renowned for bokeh and sharpness. Over 59 lenses available.
• Likely the limiting factor is autofocus absence, but for those mastering manual focus, the control over bokeh and skin rendering is exceptional.

Pentax Q Lens System

• Native Pentax Q-mount lenses (8 lenses officially) with extensive zoom, wide, pancake, and macro options.
• 5.8x crop factor means a 50mm lens behaves like ~300mm equivalent, great for telephoto; wide-angle is a challenge given sensor size.
• Sensor-based image stabilization available, compensating for handshake during telephoto or macro shots.

Autofocus Performance in Practice

• Leica: Depends on user skill; perfectly suited for deliberate compositions such as portraits and street shots where focusing is performed slowly and carefully.
• Pentax Q: Autofocus is functional and reasonably quick, though hunter-hunter behavior appears in dim light or on low-contrast subjects; subject tracking is basic but usable.

For wildlife and sports requiring fast, accurate AF, neither scores particularly well by today’s standards, but the Pentax Q offers more flexibility over Leica’s manual-only approach.

Display & User Interface: Simplicity Meets Modern Usability

The Leica’s fixed 2.5" screen may feel archaic with just 230k resolution and no live view. This demands reliance on the optical viewfinder and histogram for exposure checking, with no real-time digital preview for focusing.

The Pentax Q’s 3" LCD gives a much better interface, offering live view to compose shots, zoom to assist focusing, and playback with decent resolution.

Both cameras lack touchscreens or articulating displays, which is understandable given their launch dates and audiences.

The user interface on the Leica remains simple but limited, emphasizing direct analog control over digital menus. Pentax offers more advanced menus but still uncomplicated enough for beginners.
