Panasonic GX7 vs Pentax MX-1: An In-Depth Hands-On Comparison for Photography Enthusiasts

Choosing between two well-regarded but distinctly different cameras often boils down to understanding your personal photography style, budget, and use-case priorities. Today, I’m putting the Panasonic Lumix DMC-GX7 and the Pentax MX-1 head-to-head - two models announced in 2013 but catering to divergent creative tastes and technical needs.

Having personally tested and scrutinized thousands of cameras over 15 years, my approach here is to dive deep into real-world performance, technical specifics, and practical value for photographers at different stages. Buckle up for a detailed, candid breakdown across multiple photographic disciplines, technical specs, and usability factors.

First Impressions: Size, Build, & Ergonomics

Starting with the physical experience, the Panasonic GX7 sits in the category of Advanced Mirrorless Cameras, sporting a rangefinder-style design, while the Pentax MX-1 is a Small Sensor Compact with a fixed zoom lens. Size and handling differ significantly here:

The GX7 is a bit chunkier (123x71x55mm and 402g) but still compact for a Micro Four Thirds (MFT) mirrorless. It boasts a robust grip that fits well with larger hands - excellent for thumb and finger clubs during extended shoots. The GX7’s build leans towards a premium feel with metal construction, though it lacks weather sealing.

On the flip side, the MX-1’s dimensions (122x61x51mm, 391g) make it a pocket-friendly powerhouse. Its all-metal body with retro styling squeezes in a fast f/1.8-2.5 zoom (28-112mm equivalent), which is a unique feature in compacts of its class.

Ergonomics wise: The GX7’s larger control layout and tilting touchscreen provide more flexibility and quick access to settings. The MX-1 has a more minimalist control scheme. Neither has illuminated buttons, so nighttime operation can be fiddly, but GX7’s touch interface helps compensate.

All told, if you prioritize handling and manual control – the GX7 is a clear winner. For pure grab-and-go convenience in a metal-bodied compact, MX-1 holds its ground.

Sensor and Image Quality: The Heart of the Matter

Here’s where things get fascinating. Sensor technology is fundamental to image quality, and the differences here are stark:

• Panasonic GX7 houses a 16MP Four Thirds CMOS sensor (17.3x13.0mm), giving an effective sensor area of 224.9 mm².
• Pentax MX-1 features a much smaller 1/1.7" CMOS sensor (7.44x5.58mm) with only 12MP resolution and an area of 41.52 mm².

From my experience, sensor size impacts noise performance, dynamic range, and overall image fidelity.

Technical Deep Dive

• The GX7 scores 70 overall on DxOmark (color depth 22.6 bits, dynamic range 12.2 stops, low-light ISO 718).
• The MX-1 scores 49 overall (color depth 20.4 bits, dynamic range 11.3 stops, low-light ISO 208).

The GX7 obviously delivers cleaner images at high ISO, better dynamic range for landscapes, and richer color depth essential for portraiture. The MX-1 sensor is more constrained; expect noticeable noise above ISO 400 and limited highlight/single detail retention.

Real World Impact

• Portrait Photography: GX7’s sensor produces smoother skin tones and enables a shallower depth of field, accentuating gorgeous bokeh. MX-1, with smaller sensor and fixed lens, renders less subject isolation.
• Landscape: The expanded dynamic range and resolution of the GX7 allow for capturing intricate detail and recovering shadow/highlight detail with decent latitude.
• Low Light & Night: GX7’s noise control lets you push ISO farther, creating usable astro shots or indoor scenes that the MX-1 struggles with.

For image quality alone, the GX7 is the natural choice - especially if you want versatility and print-worthy results. The MX-1 is more a casual shooter’s tool with good daylight output.

Autofocus & Shooting Speed: Speed vs. Simplicity

Neither are beasts of speed in today’s terms, but their autofocus (AF) systems have unique strengths.

• GX7:

  • 23 Contrast-Detection focus points with face detection and live view AF.
  • AF modes include single, continuous, and tracking.
  • Max burst rate 5 fps.

• MX-1:

  • 25 contrast-detection points but no face detection or tracking.
  • Continuous AF supported but no real-time tracking.
  • Slowest continuous shooting at 1 fps.

From my hands-on testing, the GX7’s AF is more accurate and responsive, especially in well-lit conditions and when tracking moving subjects like kids or pets. The MX-1’s simpler AF system is reliable for still subjects but struggles with focus hunting in low light or rapid motion.

If you do wildlife or sports, the GX7’s 5 fps with continuous AF tracking gives you a fighting chance (albeit not pro-level). The MX-1 is better suited to landscapes, portraits, and street photography where fast focus is less critical.

Viewfinder and Rear Screen Experience

Many serious photographers need a quality viewfinder and LCD screen to compose, focus, and review shots comfortably.

• GX7 offers a bright electronic viewfinder (EVF) with 2,765k dots resolution, 100% coverage, and 0.7x magnification. Very generous compared to many MFT competitors back in 2013.
• MX-1 has no viewfinder at all. You’re shooting entirely via the LCD screen.

Both have a 3” tilting LCD - the GX7’s has 1,040k dots and touchscreen input, while the MX-1’s TFT LCD is slightly lower resolution (920k dots) and non-touch.

In daylight, the EVF on the GX7 is a real boon, offering steady framing and less glare. The MX-1’s lack of EVF means you’ll struggle in bright light relying solely on the LCD.

For photographers who rely on an adaptable shooting stance - think street or event shooters - the GX7’s EVF and touch display trump the MX-1 hands down.

Lens Ecosystem and Focal Length Flexibility

Lens selection can make or break a system, especially over the long haul.

GX7’s Micro Four Thirds Mount

This is a major advantage. Panasonic’s MFT mount boasts over 100 lenses, from Panasonic, Olympus, and third-party makers like Sigma and Voigtländer.

• Wide variety: primes, zooms, fast lenses, macro, fisheye.
• The 2.1x crop factor means a 25mm lens behaves like a 50mm full-frame equivalent - solid versatility.
• Ability to swap lenses means you can tailor your kit to sports, macro, travel, or astrophotography.

MX-1’s Fixed Zoom Lens

The MX-1 has a fixed 28-112mm equivalent f/1.8-2.5 lens. While fast and sharp, the lack of interchangeability limits scope.

• Great for walk-around shots, street photography, and modest telephoto needs.
• The f/1.8 wide aperture allows better low-light shooting than many compacts.
• Macro focus range down to 1cm is a handy bonus.

Bottom line: The MX-1’s lens is high-quality and practical for many, but the GX7’s MFT mount opens doors to creativity and shooting flexibility most compacts can’t touch.

Stability, Shutter, and Burst Mode

Both cameras offer built-in sensor-shift image stabilization - useful for handheld shooting in low light or at longer focal lengths.

• GX7 supports sensor-based stabilization with various modes, which I found effective for handheld shooting down to 1/15s shutter speeds.
• MX-1 also uses sensor-shift stabilization, though less sophisticated.

Shutter-wise both max out around 1/8000s mechanical, with GX7 adding a 1/16000s electronic shutter for silent shooting - a useful feature if you shoot concerts or weddings.

Burst shooting favors the GX7 (5fps vs 1 fps), making it somewhat more adept for action sequences, though neither matches modern flagship specs.

Video Capabilities

Today’s content creators expect decent video specs:

• GX7 shoots Full HD 1080p up to 60fps with AVCHD and MPEG-4. It includes slow-motion modes and a tilting LCD for vlog-style angles.
• MX-1 records 1080p but only up to 30fps, lacking advanced codecs.

Neither camera offers 4K or professional audio ports, and the lack of mic/headphone jacks means dedicated videographers might want to look elsewhere.

Yet for casual to moderate video use, the GX7 remains the better all-rounder - its slower compression and higher frame rates make footage more flexible in post.

Battery Life and Connectivity

• GX7 battery life: Rated around 350 shots per charge, which is average for MFT mirrorless but may require a spare battery for day trips.
• MX-1 offers ~290 shots, which is acceptable given its compact form factor.

Connectivity:

• GX7 includes built-in Wi-Fi and NFC for quick transfers and remote control.
• MX-1 relies on Eye-Fi card support, which feels more archaic and less seamless.

USB 2.0 and HDMI output are standard on both but no Bluetooth or GPS modules onboard.
