Panasonic S5 vs. Panasonic GF2: A Deep Dive into Two Generations of Mirrorless Cameras

In the ever-evolving world of mirrorless cameras, Panasonic has crafted a distinct story spanning over a decade - from the compact, approachable GF2 to the robust, full-frame powerhouse that is the Lumix S5. I’ve spent many hours with both models, putting them through rigorous tests tailored to multiple photographic disciplines and workflows. Today, we’ll unpack how these two cameras stack up across the board: image quality, autofocus, ergonomics, video features, and more. Whether you’re a beginner seeking an affordable first step or a professional hunting for a versatile hybrid workhorse, this detailed comparison will shed light on the practical real-world differences and help you find your perfect match.

First Impressions: Size, Handling, and Design Philosophy

At first glance, the Panasonic Lumix S5 and the GF2 couldn’t be more different. The GF2, launched in 2011 as an entry-level mirrorless, is petite and lightweight - with dimensions of 113x68x33 mm and weighing just 310 g. It features a rangefinder-style, minimalist design emphasizing portability and casual shooting.

In contrast, the Lumix S5, introduced in 2020, is a pro-level mirrorless camera sporting an SLR-style body at 133x97x82 mm and 714 g. This considerable jump in size and build reflects a more robust construction, extensive controls, and weather sealing - an essential feature for professional outdoor use.

One aspect I particularly appreciate about the S5 is how Panasonic has thoughtfully equipped the top plate with dedicated dials for shutter speed, exposure compensation, and ISO - something sorely lacking on the GF2. The GF2’s controls are minimal and geared toward touchscreen-centric operation, which makes the S5 vastly more ergonomic and quicker to adjust in fast-paced scenarios. The articulated 3-inch touchscreen on the S5 that flips out fully is also a stark upgrade over the GF2’s fixed, non-articulating 3-inch panel.

For photographers who prioritize portability - say, street and travel shooters - the GF2’s compact size is compelling. But if you want a camera that feels reassuringly solid in hand, with tactile, well-placed controls for serious shooting, the S5’s design philosophy wins hands down.

Sensor Technology and Image Quality: Medium Format Evolution

The heart of any camera is the sensor, and here we see one of the most profound divides. The GF2 sports a Four Thirds 17.3x13 mm sensor with 12 megapixels, buffer-limited to a max ISO of 6400. It’s an older-generation CMOS sensor paired with Panasonic’s Venus Engine FHD processor, designed for modest resolutions and daylight shooting. By comparison, the S5 boasts a full-frame 35.6x23.8 mm sensor with 24 megapixels - a doubling of resolution, and significantly larger photosites that result in better dynamic range, low-light sensitivity, and overall image quality.

In my lab and field tests, the S5’s sensor consistently outperformed the GF2 in dynamic range by a substantial margin, capturing highlights and shadows with far better tonality and less noise. This advantage makes a tangible difference in landscape and portrait photography where detail gradation is critical.

The S5’s native ISO ranges from 100 to 51200, expandable to 204800 - offering clean, usable images at high ISOs. The GF2, with a max native ISO of 6400 and significantly poorer high-ISO performance, is less suited for low-light or night photography.

This gap in sensor performance arguably positions the GF2 as a casual daylight shooter’s tool, whereas the Lumix S5 is capable of professional-grade output, adaptable to challenging lighting conditions.

Autofocus Systems: Precision and Speed Across Eras

When I compared autofocus performance, I found the Lumix S5’s 225-point contrast-detection AF system to be a marked improvement - not just in sheer coverage, but also in tracking accuracy and responsiveness under varied lighting.

The GF2’s 23 AF points are far more basic, employing contrast detection only without any phase-detection support (the S5 lacks phase detection as well but benefits from more advanced algorithms). As a result, autofocus on the GF2 felt sluggish and prone to hunting, particularly with moving subjects.

For wildlife and sports photographers, where fast and reliable AF can make or break the shot, the S5 is clearly superior. Continuous autofocus and eye detection on the S5 are surprisingly robust, locking onto eyes quickly and maintaining focus on faces–something the GF2 struggles with.

While neither has Panasonic’s proprietary animal eye AF, the S5’s general AF responsiveness still makes it quite capable for portraits, general tracking, and even some wildlife work in daylight.

Build Quality and Environmental Resilience

One of the standout advantages for professionals shooting in adverse conditions is the Lumix S5’s weather sealing, enabling dust and splash resistance. The GF2, by contrast, offers no dust, moisture, or freeze protection, necessitating much more cautious handling during travel or outdoor use.

This sealing, combined with the S5’s magnesium alloy body and robust shutter tested to 400,000 cycles, ensures durability over years of demanding photo assignments. The GF2’s plastic construction feels delicate, confirming its entry-level, casual nature.

Ergonomics, Interface, and User Experience

The Lumix S5’s 3-inch fully articulated touchscreen LCD with 1,840k-dot resolution is a delight to use. It offers bright, clear framing from all angles and responsive touchscreen controls. The electronic viewfinder (EVF) provides 2,360k-dot resolution with 100% coverage and 0.74x magnification - crucial for careful composition and shooting in bright light.

The GF2, while sporting a similar screen size, has a fixed screen with a lower 460-dot resolution and no viewfinder at all, meaning you are forced to shoot from the LCD. This compromises compositional flexibility, especially under harsh lighting or during fast movement.

From hands-on experience, I find that having both a high-res EVF and articulated touchscreen profoundly improves shooting efficiency and compositional accuracy in the field - something only the S5 affords.

Versatility through Lens Ecosystem and Compatibility

The GF2 uses a Micro Four Thirds mount with over 100 native lenses available. This ecosystem is mature, versatile, and affordable - optimized for compact bodies and smaller sensors, making it appealing for casual and travel photographers.

The S5 deploys the Leica L mount, which supports a smaller but rapidly growing selection of high-quality full-frame lenses from Panasonic, Leica, and Sigma. These lenses are generally larger and pricier, but deliver superior optical performance, bokeh quality, and low-light capability.

Interestingly, the S5’s full-frame sensor effectively doubles the pixel pitch compared to the GF2, enhancing shallow depth-of-field control - a crucial aspect for portraits and creative photography that delivers beautiful subject isolation.

For macro work, I found the S5’s sensor stabilization and focus bracketing features a boon, while the GF2 lacks such advanced controls.

Burst Speed, Buffer, and Continuous Shooting for Action Photography

For professionals shooting fast action - sports or wildlife - continuous shooting speeds can be make-or-break. The S5 manages a respectable 7 fps continuous shooting speed with electronic shutter up to 1/8000s maximum shutter speed, while the GF2 offers only 3 fps and max shutter speed of 1/4000s.

Though 7 fps is not blisteringly fast compared to flagship sports cameras, it is more than adequate for moderate sports and wildlife sequences, especially given the S5’s superior autofocus tracking.

Video Capabilities: A Tale of Two Eras

Video specifications highlight the technological chasm between these cameras.

The S5 supports 4K UHD video at 60p with 10-bit internal recording and high bitrates (up to 200 Mbps), using modern codecs such as H.264 and H.265. It has both microphone and headphone jacks for professional audio setups and sensor-based 5-axis stabilization, which dramatically reduces handheld shake. Additionally, features like 4K and 6K photo modes and timelapse recording cater to hybrid shooters blending stills and video.

Conversely, the GF2 tops out at 1080p 60fps video in AVCHD and Motion JPEG formats, with no external audio ports or in-body stabilization, limiting its video utility for serious content creators.

For videographers, the S5 represents a professional-level all-in-one solution, while the GF2 is stuck in the early days of mirrorless video, suitable only for casual use.

Battery Life, Storage, and Connectivity

The Lumix S5 comes equipped with a 440-shot battery life rating and dual SD card slots supporting SD, SDHC, and SDXC formats - features essential for extended shoots and data redundancy.

The GF2, however, offers 300 shots per charge and a single SD card slot. It’s also lacking built-in wireless connectivity and Bluetooth, whereas the S5 includes Wi-Fi and Bluetooth for seamless image transfer and remote control.

For photographers on-the-go, these technical differences translate into less downtime and more flexibility with the S5.

Price-to-Performance: Value Refined by Expectations

At its launch, the Lumix S5’s $1999 price tag positions it firmly as a hybrid professional tool intended to satisfy a broad range of demanding photographers and videographers. The GF2, launched a decade earlier at around $329, was aimed at budget-conscious entry-level consumers wanting a simple, stylish first mirrorless camera.

Our overall assessment scores reflect this gap clearly:

With the S5 outscoring the GF2 on nearly all axes, it’s vital to address value in the context of intended use. The GF2 still offers tremendous value for walkers, casual travelers, and those getting started in photography on a shoestring budget. Meanwhile, the S5’s price aligns well with the solid performance and professional tools it delivers.
