Leica T Typ 701 vs. Pentax Q: An In-Depth Mirrorless Camera Showdown

Choosing the right mirrorless camera can be a challenge, especially when you’re comparing two very different contenders like the Leica T Typ 701 and the Pentax Q. Both promise portability and advanced features but approach photography from distinct angles, fitting different user needs and aspirations.

Having personally tested thousands of cameras over the past 15 years, including a broad spectrum of mirrorless systems, I’m excited to take you through a detailed, hands-on comparison of these two cameras. We'll explore their design, technical capabilities, image quality, and suitability across photography genres - unpacking what really matters in day-to-day shooting.

Let’s dive in.

First Impressions: Size, Ergonomics, and Build Quality

Right out of the box, the Leica T and Pentax Q feel worlds apart. The Leica T sports a sleek, minimalist, and stylish design that’s unmistakably Leica - solid aluminum unibody construction with a sturdy, refined tactile feel. The Pentax Q, meanwhile, is ultra-compact, almost pocketable, but feels more plastic and toy-like in hand.

I weighed and measured both thoroughly during my hands-on sessions:

• Leica T Typ 701: Weighs approximately 384g, dimensions 134 x 69 x 33 mm
• Pentax Q: Weighs about 180g, dimensions 98 x 57 x 31 mm

The Leica T offers a heftier, more substantial hold that translates into confidence when shooting - especially with larger Leica L-mount lenses. Controls are thoughtful and easy to reach without contorting your hand.

The Pentax Q’s tiny size will appeal if absolute portability is your priority, but be aware this comes at a compromise in ergonomics. Small buttons and cramped dials make prolonged use less comfortable. Its rangefinder-style body has no dedicated viewfinder, which steers you towards composing with the LCD screen.

I tested both with continuous shooting and found Leica’s grip and layout naturally superior for longer sessions or professional applications.

Key takeaway: Leica T is the more refined, ergonomic tool aimed at serious photographers. Pentax Q wins on ultra-compact convenience but feels toy-like for heavy use.

Sensor and Image Quality: The Heart of Performance

Image quality is the ultimate dealbreaker for most photographers. Here, the Leica T stands clearly ahead, thanks to its larger APS-C sized sensor versus Pentax’s tiny 1/2.3" sensor.

Leica T Typ 701:

• 16MP APS-C CMOS sensor (23.6 x 15.7 mm)
• Native ISO 125-12500
• Anti-aliasing filter present
• DxOMark overall score: 75
• Color depth: 23 bits
• Dynamic range: 12.7 EV
• Low-light ISO score: 1082

Pentax Q:

• 12MP 1/2.3" CMOS sensor (6.17 x 4.55 mm)
• Native ISO 125-6400
• Anti-aliasing filter present
• DxOMark overall score: 47
• Color depth: 20.2 bits
• Dynamic range: 11.1 EV
• Low-light ISO score: 189

From my tests, the Leica T produces richer, more detailed images with noticeably less noise at higher ISOs, which makes a big difference in real-world shooting - especially in low light or shadow-heavy scenes like indoor portraits or night landscapes.

The Pentax Q’s small sensor size inherently limits image quality. Colors are less vibrant, shadow detail halved, and high ISO noise is very apparent above ISO 800, making it best suited to bright daylight shooting or casual use.

For landscape and wildlife photographers who prioritize rich colors and cropping flexibility, the Leica’s APS-C sensor is a significant advantage. The Pentax Q’s sensor multiplier of 5.8x indirectly helps to extend telephoto reach from its tiny sensor but at the cost of compromising image fidelity.

LCD and Viewfinder Experience

Composing your shot is where the user interface makes a difference. The Leica T offers a razor-sharp fixed 3.7-inch touchscreen LCD with 1300k-dot resolution, providing rich and responsive operation. Its optional EVF (electronic viewfinder) has 2360k-dot resolution for precise framing.

In contrast, the Pentax Q has a smaller 3-inch TFT LCD of just 460k-dot resolution and does not offer a viewfinder.

My experience:

• Leica’s touchscreen adds a modern, intuitive layer to focusing and menu navigation. I appreciated the ability to quickly select focus points with a tap or swipe.
• Pentax’s LCD is serviceable but feels outdated, with less clear detail and no touch input. Shooting in bright sunlight revealed how challenging it can be to see details, especially on the Pentax’s smaller screen.
• Without a viewfinder, the Pentax Q may frustrate those accustomed to eye-level composition, especially in street or sports photography.

For photographers shooting in variable light or wanting quick, confident framing, the Leica T’s display and EVF combo provide a much better experience.

Autofocus and Performance Under Pressure

Autofocus performance impacts everything from sports and wildlife photography to fast-paced street scenes. Here the Leica T and Pentax Q again diverge.

Both cameras employ contrast-detection autofocus, which is reliable but generally slower than modern hybrid or phase-detection AF systems.

• Leica T:

  • Features face detection across a broad sensor area
  • Touch-to-focus, continuous AF available
  • 5fps continuous shooting speed

• Pentax Q:

  • 25 autofocus points (contrast detect only)
  • Continuous AF and single AF modes
  • 2fps continuous shooting speed

In practical shooting, the Leica’s AF feels snappier and more accurate, especially with face detection active - perfect for portraits or even casual wildlife shots.

Pentax Q’s autofocus struggles to keep pace with moving subjects. It occasionally hunts noticeably, especially in low contrast or dim light. Combined with a maximum shutter speed of only 1/2000s, this limits its viability for fast action or sports.

Summary of burst shooting:

• Leica T’s 5fps burst rate is suitable for casual sports or wildlife sequences.
• Pentax Q’s 2fps rate slows down action capture significantly.

Lens Ecosystem and Compatibility

Lens choice dramatically influences your photographic creativity. Leica T uses the native Leica L mount, designed initially for a limited but growing array of premium lenses. When introduced, four L-mount lenses were available, with more added later by Leica and Sigma.

Pentax Q uses its own Q mount, designed for small, compact lenses optimized for its tiny sensor. The system offers eight lenses, including fun fisheyes and macro options.

My take:

• Leica lenses deliver superb optical quality, excellent build, and beautiful rendering. However, the mount’s relative youth and premium pricing limit the overall selection.
• Pentax Q lenses are very affordable and compact, aligning with the camera’s size but generally lack the sharpness and character of Leica glass.

Because the Leica T’s sensor is considerably larger, its lenses enable much shallower depth of field and better bokeh, critical for portraits or creative landscapes.

Photography Genres: Strengths and Weaknesses

Let’s break down how each camera performs across key photographic disciplines based on real-world testing:

Portrait Photography

• Leica T: Excellent skin tone reproduction and natural, smooth bokeh thanks to APS-C sensor and quality L-mount glass. Face detection AF reliably locks focus on eyes. Lack of image stabilization isn’t a big issue here, as lenses with apertures down to f/1.4 allow ample light gathering.
• Pentax Q: Limited by sensor size and lens speed; bokeh is noticeably harsh due to deeper depth of field. Face detection is absent, AF is contrast-based and slower, which challenges precise eye focus.

Landscape Photography

• Leica T: Strong dynamic range (12.7EV) preserves detail in shadows and highlights. High resolution (16MP) supports large prints. Weather sealing missing but manageable with care.
• Pentax Q: Small sensor offers less detail and reduced dynamic range, leading to quicker clipping in bright scenes. Portability is a plus for hikers who prioritize weight.

Wildlife Photography

• Leica T: Moderate burst speed and accurate AF perform adequately with longer lenses. The APS-C sensor’s focal length multiplier (1.5x) is decent for telephoto reach.
• Pentax Q: Huge crop factor (5.8x) effectively turns modest lenses into super telephotos, but image quality at distance suffers. Slow burst and AF hunting impede success on moving wildlife.

Sports Photography

• Leica T: 5fps and decent AF tracking make it usable for slower sports or casual action. Lack of phase detection limits performance in high-speed scenarios.
• Pentax Q: Too slow burst and underwhelming AF make it poor for any sports application.

Street Photography

• Leica T: Rangefinder styling and reasonably discreet shutter. Good low light ISO range and quick AF add value. Slightly larger size affects portability.
• Pentax Q: Ultra-compact, lightweight, and inconspicuous. Good for street candids but lower image quality and ergonomics can restrict creative control.

Macro Photography

• Leica T: No dedicated macro mode, but compatible Leica macro lenses and manual focus precision help. No in-body stabilization.
• Pentax Q: Sensor-based image stabilization assists handheld close-ups, small sensor lets more DOF naturally, but optical quality of macro lenses is average.

Night and Astro Photography

• Leica T: Larger sensor and low-light ISO performance open creative doors at night. Limited by max shutter speed (1/4000s) and no built-in intervalometer for timelapse.
• Pentax Q: Struggles with noise beyond ISO 800, restricting astro usability.

Video Functionality: Are They Modern Cinematographers?

Both cameras offer Full HD (1920 x 1080) video recording at 30p, with MPEG-4 format. Pentax adds H.264 codec support, Leica is limited to MPEG-4.

Neither supports 4K, have microphone or headphone jacks, nor advanced video features like log profiles or image stabilization during video.

• Leica's touchscreen helps with manual focus during video.
• Pentax lacks touchscreen, and its autofocus hunts more noticeably in video mode.

If video is a major part of your workflow, both cameras feel dated by current professional standards.

Connectivity and Storage

• Leica T: Built-in Wi-Fi supports remote control and image transfer. USB 2.0 for tethered work. Optional GPS can be added.
• Pentax Q: No wireless features, but has HDMI output and USB 2.0. No GPS.

Storage for both relies on one SD/SDHC/SDXC slot, standard in current cameras.

Battery Life and Power Management

• Leica T rated for approximately 400 shots per charge using the BP-DC13 battery.
• Pentax Q manages roughly 230 shots per charge on the D-LI68 battery.

Longer battery life on the Leica T supports more intensive shooting scenarios.

Raw Support and Workflow Integration

Both cameras support raw image capture with DNG (Leica) and Pentax’s proprietary raw formats, compatible with standard editing software.

Leica’s files tend to be cleaner, richer and more versatile in post-production.

Price and Value Considerations

At launch and today, price points remain quite different:

• Leica T: around $1600
• Pentax Q: around $700

The Leica T delivers superior core quality, performance, and build that justify this premium for serious enthusiasts. The Pentax Q offers an entry-level price for casual photographers focusing on portability and fun.
