Panasonic Lumix G1 vs Sony NEX-F3: A Hands-On Comparison of Two Entry-Level Mirrorless Cameras

In the rapidly evolving world of mirrorless cameras, standing apart demands a complex balancing act - image quality, user experience, versatility, and value. Today we dissect two pioneering entry-level models from the Micro Four Thirds and APS-C camps: the Panasonic Lumix DMC-G1 (hereafter the G1) and the Sony Alpha NEX-F3. Released three years apart, each brought fresh ideas to mirrorless design, catering to enthusiasts stepping up from compact cameras or DSLRs seeking a smaller form factor. Having tested both extensively under diverse shooting conditions, I’ll share a comprehensive head-to-head analysis rooted in practical use and technical evaluation.

First Impressions: Size, Build, and Handling Differences

The Panasonic G1 debuted in early 2009 as one of the first consumer mirrorless cameras that truly embraced SLR-style ergonomics. By contrast, the Sony NEX-F3, launched in 2012, adopts a more compact, rangefinder-inspired profile aimed at casual yet serious photographers.

Physically, the G1 measures 124x84x45 mm and weighs 360 grams, sporting a chunkier grip and straightforward control layout designed for stability during longer shoots. The NEX-F3, at 117x67x42 mm and 314 grams, feels lighter and sleeker in hand but sacrifices some tactile control robustness. While I appreciated the G1’s deliberate heft for balanced telephoto use, the NEX-F3 wins on portability and pocketability, especially for street and travel photographers.

Both are constructed from polycarbonate with no environmental sealing, so neither inspires confidence in extreme weather. However, their solid build quality exceeds typical entry-level plastics, feeling resilient to daily wear.

Controls reflect their design ethos: the Panasonic’s top dials are prominent and easy to operate, giving quick access to shutter speed and exposure modes. The Sony’s layout is cleaner but requires more menu navigation, which might slow seasoned users during fast-paced scenarios. Neither camera features illuminated buttons nor touchscreen input - common limitations of their era but still relevant in today’s touchscreen-saturated market.

Sensor Technology and Image Quality: Four Thirds vs APS-C

At the heart of any camera comparison lies sensor performance. The G1 sports a 12-megapixel Four Thirds CMOS sensor measuring 17.3x13 mm (approximately 225 mm² area), while the NEX-F3 employs a larger 16-megapixel APS-C CMOS sensor sized 23.4x15.6 mm (around 365 mm²). This difference significantly impacts image quality dynamics.

In hands-on testing, the NEX-F3 delivers noticeably cleaner files with more finely rendered detail, thanks to its higher native resolution and sensor scale advantage. Color depth measured by DxOMark records a superior 22.7 bits on the Sony compared to 21.1 on Panasonic, translating to richer color gradations - critical for portrait and landscape photographers requiring smooth skin tones and subtle hues.

Highlight retention and dynamic range also favor the NEX-F3, with a 12.3 EV dynamic range compared to 10.3 EV on the G1. This difference proves especially tangible in high-contrast scenes like backlit portraits or landscapes with bright skies and shadows. While the G1 still produces respectable images, shadows clip earlier and highlight recovery is more limited.

Low-light performance furthers this divide. The G1 caps native ISO at 1600 (3200 boosted), suitable for moderate indoor or twilight shooting but noisy beyond ISO 800 in my tests. Conversely, the NEX-F3’s max native ISO reaches an impressive 16,000, offering usable images at ISO 3200 and acceptable noise levels up to 6400 under careful processing. This opens options for event or night photographers on a budget.

Both sensors feature anti-aliasing filters, slightly softening pixel-level sharpness but helping to avoid moiré in complex patterns. Raw support is standard on both, affording maximum creative latitude.

Display and Viewfinder: Live Preview with a Twist

Having a high-quality LCD and viewfinder system is crucial for composing and reviewing shots accurately - especially in bright or dynamic environments.

The Panasonic G1 boasts a fully articulating 3-inch, 460K-dot screen ideal for low-angle or overhead shooting, popular with macro and creative portrait perspectives. Its articulating design predates many competitors and remains a standout feature for flexible framing. However, the screen’s resolution is modest by today’s standards, leading to somewhat grainy playback images.

Sony’s NEX-F3 features a tilting 3-inch screen with nearly double the resolution - 920K dots - rendering preview images with noticeably greater crispness and vibrancy. The screen isn’t fully articulating but offers sufficient tilt angles for common shooting inclinations.

Neither camera includes a built-in electronic viewfinder (EVF); notably, the NEX-F3 accepts an optional add-on EVF, whereas the G1 integrates a modest but serviceable electronic viewfinder with 100% coverage. While I found the G1’s EVF workable in bright sunlight, it feels outdated and cramped compared to modern standards.

For photographers who prioritize live view performance, the Sony’s sharper screen and optional EVF flexibility advantage the NEX-F3 by a clear margin.

Autofocus Performance: Contrast Detection and User Realities

Both cameras employ contrast-detection autofocus systems exclusively, lacking the hybrid or phase-detection hybrids that would become popular later.

Panasonic’s G1 autofocus is competent for its generation, but relatively slow - particularly in continuous mode, where focusing hunts near busy backgrounds or in low light. It offers single, continuous, and multi-area AF modes but lacks face or eye detection - a notable omission for portraits.

Sony’s NEX-F3 demonstrates a marked improvement: faster focus acquisition, supported by 25 focus points providing broader coverage and better subject tracking. While advanced face detection is absent, its speed and accuracy lend confidence in dynamic shooting environments like street photography or casual sports.

Neither camera supports animal eye detection or focus bracketing/stacking, limiting macro and wildlife photography potentials. But for general-purpose work, the NEX-F3’s autofocus system feels more responsive and reliable, reducing missed shots - a key advantage for fast-moving subjects.

Burst Shooting and Buffer Depth: Capturing Action

Sports and wildlife photographers demand cameras that can sustain high frame rates with deep buffers for capturing sequences of decisive moments.

The Panasonic G1 manages a modest 3 fps burst rate, sufficient for still life or slow action but frustratingly slow for anything faster. Buffer clearing times are average given its internal processor limitations.

Sony’s NEX-F3 doubles that speed to 6 fps, halving shutter lag and improving capture chances for fleeting expressions or movements. While still not blazing fast by today’s standards, this increase benefits enthusiast sports shooters or street photographers seeking to freeze motion.

Neither camera features electronic shutters or silent shooting modes, restricting stealth capabilities in quiet environments.

Lens Ecosystem and Mount Compatibility

An often overlooked but critical factor for long-term system investment is the available lens ecosystem.

The G1 mounts the Micro Four Thirds system with around 107 native lenses at launch and a steadily growing catalog, including wakeup primes and versatile zooms geared toward all genres. The 2.1x crop factor implies a significant focal length multiplication - making 25mm effectively 50mm, a classic 1:1 DSLR “normal” field of view.

The NEX-F3 uses Sony’s E-mount APS-C system, which initially featured close to 120 lenses covering wide angles to super-telephoto primes and zooms. The 1.5x crop factor reduces the telephoto requirement for wildlife shooters compared to the G1 but with a slightly shallower depth of field due to sensor size. Sony’s ecosystem has since expanded enormously, especially with third-party support.

Both mounts allow adaptation of legacy lenses, but Sony’s E-mount is more flexible for longer-term use given its lens variety and futureproofing.

Video Capabilities: A Clear Win for the Sony NEX-F3

Videographers or hybrid shooters will find a waking giant in the NEX-F3.

The Panasonic G1 lacks any video recording capability - purely designed for stills photography, a significant limitation by modern standards. This reflects its 2009 release date before mirrorless cameras commonly merged still and motion functions.

Sony’s NEX-F3 shoots 1080p Full HD video at 60 and 24 fps, as well as lower resolutions, in both AVCHD and MPEG-4 formats. Video autofocus is contrast-based but reasonably smooth. Internal stabilization is not present, requiring stabilized lenses or gimbal support.

The NEX-F3 forgoes microphone and headphone jacks, limiting professional audio options, yet nonetheless represents a compelling entry-level video tool, especially combined with its superior sensor.

Battery Life, Storage, and Connectivity: Endurance Matters

In fieldwork, battery stamina and storage flexibility are essential for uninterrupted sessions.

The Panasonic G1’s CIPA-rated battery life stands at 330 shots per charge, which I found realistic during long daylight shoots but necessitates spares for extended travel.

Sony’s NEX-F3 impresses with 470 shots per charge, delivering longer usage between changes - the difference may be partly attributed to efficient processor design.

Both rely on a single removable SD card slot, with Panasonic supporting SD, MMC, and SDHC, while Sony adds SDXC and Memory Stick Pro compatibility, offering more futureproof storage options.

In connectivity, neither camera features wireless integration such as Wi-Fi or Bluetooth. Sony does support Eye-Fi card connectivity, enabling limited wireless transfer, but it’s an indirect solution compared to modern cameras’ inbuilt connectivity.
