Panasonic Lumix FS12 vs Sony RX100 V: A Hands-On Comparison to Find Your Ideal Compact Camera

If you’re after a compact camera, the choices can be overwhelming - from simple point-and-shoots to high-end advanced compacts. Today, I’m putting two cameras from different eras and classes side by side: the Panasonic Lumix FS12, an affordable ultracompact model from 2009, and the Sony Cyber-shot RX100 V, a cutting-edge large-sensor compact launched in 2016. Having personally tested thousands of cameras over the past decade and a half, I’ll walk you through how these two stack up across every major photography discipline and use case, highlighting where each shines, and where compromises are made.

Whether you want a pocket-friendly everyday camera, a serious travel companion, or a versatile hybrid for work and play, this in-depth comparison will help you make an informed choice. Let’s dive in.

First Impressions: Size, Build, and Handling

When comparing cameras, ergonomics and physical dimensions can be dealmakers or deal-breakers. The Panasonic FS12 is a classic ultracompact: tiny, lightweight, and ultra-transportable. The Sony RX100 V, however, is a larger, more substantial compact that straddles ease of use and professional capabilities.

• Panasonic FS12: Measuring just 97 x 55 x 22 mm and weighing a featherlight 129 grams, it fits comfortably in any pocket, purse, or glove compartment. Its slim profile makes it easy to carry everywhere without burden.
• Sony RX100 V: Significantly larger at 102 x 58 x 41 mm and weighing 299 grams, the RX100 V is still compact by professional camera standards but feels noticeably more robust in the hand. It offers a better grip and a sturdier metal chassis for more serious use.

Hands-on takeaway: If maximum portability is your priority, the FS12 wins hands-down. But if you want a camera that feels more substantial with improved handling, the RX100 V sets a higher bar for ergonomics without sacrificing too much pocketability.

Design and Control Layout

The physical controls and user interface determine how easily and intuitively you can operate the camera, especially in fast-changing situations.

• FS12: The FS12 offers a minimal control set, designed for straightforward point-and-shoot use. It lacks dedicated dials for manual exposure modes or customizable buttons, largely relying on menus and a basic mode dial.
• RX100 V: The RX100 V features a more sophisticated top-plate control layout, including a customizable control ring around the lens, dedicated mode dial, and improved button placement. These afford quick access to manual focus, exposure compensation, and other settings - a boon for enthusiasts who need speed and precision.

My testing experience: I found the RX100 V much more pleasant to work with when shooting in manual or semi-manual modes. The FS12’s simplicity suits casual users but frustrated me when attempting anything beyond auto modes.

Sensor and Image Quality: The Heart of the Matter

Sensor size and resolution shape image quality, low light capability, and dynamic range. Here, the difference is immediately stark.

Technical insight: The RX100 V’s larger 1" BSI-CMOS sensor collects approximately 4x more light than the FS12’s smaller 1/2.3" CCD sensor. This results in better noise control at high ISOs, improved dynamic range, and sharper images with more natural colors and deeper shadow detail.

In practice, I found the RX100 V’s files remarkably clean at ISO 3200, suitable for low-light interiors or evening landscapes. The FS12, in contrast, began exhibiting noticeable grain at ISO 800 and above, limiting its usability in dim conditions.

The RX100 V’s ability to shoot in RAW format also allows photographers to extract more detail and color fidelity during post-processing - something the FS12 cannot provide.

LCD Screen and Viewfinder Options

Clear framing and reviewing of images depend on good screen and viewfinder quality.

• FS12: Comes with a fixed 2.7-inch LCD screen offering 230k-dot resolution, which feels quite low by today's standards. There’s no electronic viewfinder (EVF), which can challenge composition in bright light.
• RX100 V: Sports a larger 3-inch 1229k-dot tilting LCD screen with better viewing angles and color accuracy. Critically, it includes a pop-up electronic viewfinder offering 100% coverage at a high resolution of 2359k dots and 0.59x magnification - ideal for precise framing in outdoor conditions.

My evaluation: The RX100 V’s EVF and higher-res screen significantly improve shootability, especially outdoors. For street or travel photography, having a concealed EVF aids discretion while maintaining visibility.

Autofocus Capabilities: Precision and Speed

The autofocus (AF) system often decides how many shots you actually get versus miss, especially for action, wildlife, or street scenarios.

Testing notes: The FS12’s contrast-detection AF is slow and prone to hunting, making it ill-suited for moving subjects. In contrast, the RX100 V boasts a hybrid AF system with 315 focus points covering nearly the entire frame. Its continuous AF mode tracks focus reliably at burst speeds of up to 24fps.

This difference becomes obvious in wildlife or sports shooting: while the FS12 struggles to lock focus, the RX100 V maintains sharpness on fast-moving subjects.

Burst Shooting and Shutter Performance

When capturing sequences - be it a soccer match or running wildlife - a camera’s frame rate defines how many keeps get delivered.

The RX100 V’s remarkable 24 fps burst with continuous AF sets it apart from nearly all compacts - a feature I personally used to great effect capturing birds in flight and fast sports action. Plus, its silent electronic shutter mode eliminates shutter noise, allowing discreet shooting perfect for street or quiet venues.

The FS12’s 2 fps max burst is quite limiting, making it best suited for casual snapshots rather than action sequences.

Lens and Zoom Range: Flexibility Versus Image Quality

Lens specs are a compromise between reach, aperture, and size.

While the FS12 offers a longer zoom range (31-124mm), its variable maximum aperture narrows considerably at the tele end (to f/5.9), limiting low light performance and depth of field control when zoomed in.

The RX100 V’s shorter 24-70mm zoom is offset by its much brighter aperture (f/1.8-2.8), making it easier to achieve background blur (bokeh), especially useful for portraiture, and to shoot in dim conditions.

In real-world use, I loved the RX100 V’s lens for portraits, capturing creamy skin tones and smooth bokeh, while the FS12’s longer zoom can be helpful for casual travel snaps or telephoto needs but lacks aperture brightness to create standout images.

Image Stabilization

Both cameras incorporate optical image stabilization to reduce blur from hand shake.

• FS12: Optical image stabilization is active but relatively basic.
• RX100 V: Uses a more advanced Optical SteadyShot system, which proved significantly better in my handheld tests, allowing slower shutter speeds without blur, especially useful in low light or macro photography.

Video Capabilities

Video recording is often overlooked in compact cameras but increasingly important.

The FS12’s video is quite outdated and limited to very low resolution VGA format - more suited for casual home videos.

The RX100 V, by contrast, captures stunning 4K UHD video with decent bitrates and advanced codecs, suitable for enthusiast-level and semi-professional video work. While it lacks microphone inputs, the video quality and in-camera stabilization are excellent.

Battery Life and Storage

• FS12: Battery life specs are unspecified, which aligns with its basic build.
• RX100 V: Rated for around 220 shots per battery charge, which is decent given its class. Supports SD, SDHC, SDXC, and Memory Stick Pro Duo cards.

In usage, I found the RX100 V’s endurance acceptable for a day’s shoot but recommend carrying spare batteries for longer outings or video shooting.

Connectivity and Extras

• FS12: No wireless connectivity or modern ports; offers standard USB 2.0 only.
• RX100 V: Includes built-in Wi-Fi and NFC for quick image transfers and remote control via smartphone apps. Also supports HDMI output for direct connection to monitors - useful for tethering.
