Panasonic FS7 vs Panasonic GM1: A Deep Dive into Two Generations of Compact Imaging

When it comes to compact cameras, the Panasonic Lumix line has long offered intriguing options targeting both casual shooters and enthusiasts seeking portability without compromising too much on capability. Today, I’m putting two very different beasts side by side: the Panasonic FS7, an ultracompact point-and-shoot from 2009, and the 2013 vintage Panasonic GM1, an entry-level Micro Four Thirds mirrorless camera that raised the bar for small, capable interchangeable lens cameras at its launch.

At first glance, these cameras live in different worlds - one fixed lens and relatively simple, the other mirrorless with a sizable lens ecosystem. But both represent Panasonic’s approach to portable photography in their respective eras. After extensive hands-on testing, I’m sharing my practical insights on image quality, handling, performance, and versatility to help you pick the right tool for your photography ambitions.

Compactness and Ergonomics: Holding the Cameras in Your Hand

The Panasonic FS7 is true pocketable gear from a decade ago: tiny, lightweight, and designed for effortless snapshots. Its dimensions of 97x54x22 mm and featherlight 139 grams make it a no-brainer to carry everywhere - perfect for those spontaneous photo opportunities where size or weight could deter you.

Compare that to the GM1’s 99x55x30 mm body weighing 204 grams - visibly bulkier and thicker, but still remarkably svelte for a mirrorless camera with interchangeable lenses. It fits comfortably in one hand and even some larger pockets if needed, but it’s clear Panasonic pushed technical boundaries with the GM1’s size, packing a large sensor into a distinctly small frame.

Ergonomically, the FS7 opts for minimalism with a straightforward button layout and no built-in viewfinder, operating largely as a point-and-shoot without advanced controls. The GM1 compensates for its compact silhouette with more intuitive button placement, a more tactile grip, plus a capacitive touchscreen that facilitates focus and menu navigation.

For users who prioritize immediate access to settings or the tactile joy of dial and button control, the GM1 wins hands down. On the other hand, if you prefer grabbing a camera that feels almost invisible in your pocket and just snapping without fuss - FS7’s simplicity has its charm.

Sensor Technology and Image Quality: The Heart of the Camera

This is where the chasm widens substantially.

The FS7’s 1/2.5-inch CCD sensor measures just 5.744 x 4.308 mm (24.74 mm² area) and tops out at 10 megapixels. That sensor size and pixel count were typical back in 2009’s ultracompacts but pale against modern standards. Sensitively capped at ISO 1600 with boost up to 6400, image quality is usable in bright daylight but lacks punch, especially in low light or challenging contrast.

By contrast, the GM1 sports a much larger Four Thirds CMOS sensor measuring 17.3 x 13 mm (224.9 mm² area) - nearly 9 times the surface area - with a 16MP resolution. This sensor size advantage yields significantly better image quality: richer colors, greater dynamic range, and lower noise at higher ISO sensitivities up to 25600 native (a theoretical max, but still impressive for low-light).

From my controlled studio tests and real-world shooting, the GM1’s dynamic range (~11.7 EV measured via DxOmark metrics) far exceeds what the FS7 can muster, allowing you to recover details in shadows and highlights better. The GM1’s files contain more color depth and fidelity, thanks to improved sensor tech, processing pipelines, and shooting flexibility via raw support - which the FS7 completely lacks.

If you need sharp, clean images suitable for prints, cropping, or professional use, the GM1’s image quality will serve you far better. For casual snapshots destined primarily for web or social media, the FS7 still surprises for its vintage class.

Autofocus and Focusing Flexibility: Getting the Shot in Focus

The FS7 relies on contrast-detection autofocus with 9 fixed focus points, offering single-area AF only - simple but slow and prone to hunting, especially in low contrast or moving subjects. Face detection and eye autofocus don’t exist here, so you have to keep your subject centered as best possible, or use manual focus override zones (if available).

The GM1, however, impressed me with a more sophisticated contrast-detection AF system featuring 23 focus points and the ability to use face detection and tracking AF, which are invaluable for portraits or moving subjects. The touch-enabled screen facilitates precise AF point selection, and continuous autofocus can track subjects effectively in many scenarios, including some modest action.

For wildlife, sports, or street photography where speed and tracking matter, the GM1 is unquestionably better suited. The FS7’s AF remains serviceable for stationary subjects in decent light but can frustrate when quick reaction times or precision are critical.

Build Quality and Weather Resistance: How Tough Can They Go?

Neither the FS7 nor the GM1 incorporates weather sealing or rugged body features such as dustproofing, waterproofing, or freezeproofing. Both are primarily designed for fair-weather shooting and gentle handling.

The FS7’s primarily plastic body feels lightweight but less robust, while the GM1 sports a sturdier build with metal elements that better withstand occasional knocks and wear. However, neither is a rugged camera - so outdoor photographers in harsh environments should look elsewhere or be prepared to shield these cameras carefully.

Screen and Viewfinder: Composing Your Shots in Comfort

The FS7 opts for a fixed 2.7-inch LCD with just 230k-dot resolution and no touchscreen - basic but functional for framing in bright conditions. Without an EVF, you’re reliant entirely on this somewhat dim and low-res screen, which can struggle under sunlight.

By contrast, the GM1 includes a sharper 3-inch LCD at 1.04 million dots, touchscreen-enabled with wide viewing angles. Though it doesn’t have a built-in viewfinder, the superior screen visibility and touch-focus convenience significantly enhance usability. This is a big bonus in bright outdoor scenarios and when shooting video.

If you are content composing through a screen alone, the GM1 provides a far more pleasurable experience, reducing eyestrain and mistakes.

Lens Systems and Versatility: Fixing Your Focus on Options

Lens is the canvas for creativity, and here the differences become stark.

The FS7 sports a fixed 33–132 mm equivalent zoom lens (4x optical zoom), with a moderate max aperture of f/2.8-5.9 - decent for an ultracompact from its era but limiting for shallow depth of field or low light.

The GM1’s claim to fame is the Micro Four Thirds lens mount - with access to Panasonic’s own lenses and a vast third-party ecosystem totaling over 100 lenses, ranging from super-wide primes to telephotos and specialist optics like macros and fast portraits. Whether you want a creamy bokeh for portraits, long reach for wildlife, or macro precision, the GM1 can deliver - provided you’re willing to carry and invest in glass.

This flexibility has profound implications: The FS7 is a convenience camera. The GM1 is an expandable creative tool capable of adapting to nearly every photography style.

Continuous Shooting and Speed: Capturing the Moment

If fast action is your jam, here’s the scoop:

The FS7 offers 3 fps continuous shooting - fine for casual bursts but insufficient for serious sports, wildlife, or fast street photography. Autofocus is single-shot only, so focus won’t change during capture.

The GM1 boasts a 5 fps burst rate with autofocus tracking - not blazing compared to flagship sports cameras, but enough to capture moderate action scenes. The electronic shutter with speeds up to 1/16000s allows freezing very fast action or shooting wide apertures in bright light.

Action shooters needing precise focus and decent frame rates will favor the GM1.

Video Capabilities: Moving Images with Modern Features

Both cameras can shoot video, but the GM1 markedly advances the experience.

The FS7 records only low-resolution footage at 848x480 pixels max in Motion JPEG format - frankly very limited by today’s standards.

The GM1 steps up with Full HD 1080p recording at interlaced 60i, progressive 24p, and 720p options, using MPEG-4 and AVCHD codecs. No 4K, but respectable for an entry-level mirrorless of its time. Optical image stabilization resides in the lens rather than the body, so video smoothness depends on glass choice.

Neither has microphone or headphone ports, limiting audio prowess, but the GM1’s video modes offer greater versatility for casual filming or travel video.

Battery Life and Storage: Staying Powered and Saving Shots

The FS7’s battery life isn’t explicitly stated but expect modest endurance typical of compact cameras, likely under 200 shots per charge.

The GM1 officially offers around 230 shots per battery charge - again modest, but enough for a day’s casual shooting with strategic power management. Both cameras use standard SD card formats, but the GM1 supports SDXC for large capacity cards.

While neither excels in long shooting sessions, careful usage and spare batteries will get you through standard outings.

Connectivity and Wireless Features: Sharing and Control

Connectivity was minimal on the FS7 - no wireless options at all, only USB 2.0 and HDMI outputs.

The GM1 integrates built-in wireless - an important feature for 2013 - enabling image transfer, remote control, and tethering via Panasonic’s smartphone apps. This connectivity leap vastly improves workflow for social shooters and travelers.

Bluetooth, NFC, or GPS are absent on both.

Practical Performance Scores and Use-Case Suitability

Looking at objective performance scores (where available) and practical experience, the GM1 leads in image quality, versatility, autofocus, and video - consistent with its newer generation and more advanced design.

The FS7 holds up only as a very compact budget option geared for casual snapshots and travel where simplicity and pocketability matter most.

Breaking down by photography type:

• Portraits: The GM1’s larger sensor, interchangeable fast lenses, face detection autofocus, and raw support produce superior skin tones, creamy bokeh, and accurate eye tracking. The FS7 struggles with flat tonality and lack of selective focus.

• Landscape: GM1 offers wider aspect ratios, higher resolution, and better dynamic range for imaginative landscape work. FS7’s limited sensor and lens power restrict scope.

• Wildlife: GM1 with fast AF and adaptable telephotos has clear advantage; FS7’s slow AF and fixed moderate zoom limit action captures.

• Sports: Only GM1’s higher burst rate and AF tracking are viable.

• Street: FS7 scores with absolute compactness, but GM1’s discretion and touch AF compensate for size.

• Macro: GM1 supports dedicated macro lenses with fine focus controls; FS7 macro limited to fixed lens focus at 5cm.

• Night/Astro: GM1’s greater ISO range and raw files enable night shots that FS7 can’t approach.

• Video: GM1’s Full HD crushes FS7’s standard definition.

• Travel: FS7 lightweight and pocket ready, but GM1’s versatility and quality better for serious travel photography.

• Professional Work: GM1 raw support and output quality make it the only candidate here.

Final Thoughts: Which Camera Fits Your Needs?

The Panasonic FS7 and GM1 illustrate significant evolution in compact camera technology within a few years. They cater to fundamentally different users.

• If you want a supremely portable, idiot-proof point-and-shoot with simple automatic modes, a lightweight body, and a tight budget (~$160), the FS7 will deliver snapshots without fuss. It’s best seen as a throwback portable - nostalgia meets minimalism.

• If you’re serious about image quality, flexibility, and creative control - or are stepping into mirrorless photography - the GM1 is a more future-proof investment. At around $750 (refurbished or used prices vary), you’re paying for substantially better sensor tech, autofocus, lens choices, and video.
