Panasonic FS15 vs Sony RX100 VII

Head to Head: Panasonic Lumix FS15 vs Sony RX100 VII - A Tale of Two Compacts

If you had asked me to compare the Panasonic Lumix DMC-FS15 and the Sony Cyber-shot DSC-RX100 VII a decade ago, I’d have raised an eyebrow - and probably said it was like comparing a tricycle to a Ferrari. Yet here we are, with the retro-2009 Panasonic ultracompact still hanging on in the conversation alongside Sony’s 2019 powerhouse. It’s an interesting matchup because these two cameras come from radically different eras and philosophies about what a compact camera should be.

In this deep dive, I’ll walk you through everything from sensor magic to street photography suitability, weaving in my hands-on experience testing thousands of cameras over the years. By the end, you’ll know which model deserves a spot in your bag - or if the FS15 is best left as vintage curiosity.

Let’s jump in.

Size Does Matter: Ergonomics and Portability Face-Off

First impressions count - and in the ultra-competitive compact camera world, every millimeter and gram matters. The Panasonic FS15 is a classically tiny camera: ultracompact body measuring 97 x 54 x 22 mm and tipping the scales at a featherlight 136 grams. It slips easily in a pocket and begs for casual snapshots without attracting attention.

In contrast, the Sony RX100 VII is decidedly chunkier at 102 x 58 x 43 mm and 302 grams – more than double the FS15’s weight. That heft comes with a tradeoff: beefier grip, more substantial build, and a lens extending much further to deliver a broader zoom range. This isn’t your grab-and-go candy bar camera but a serious compact intended for photographers demanding versatility.

From experience, I find the FS15 perfect for unobtrusive street shooting or quick family snaps, but the RX100 VII’s larger body allows for better handling during longer sessions. The RX100 VII’s lens deployment and controls feel more reassuring when shooting fast-moving subjects, despite the added bulk.

Unless pocketability is your #1 priority, the RX100 VII’s ergonomics and physicality are superior for serious use.

Under the Hood: Sensor Size and Image Quality Insights

No comparison is complete without dissecting image quality, and that leads us straight to sensors - the heart of any camera. The FS15 sports a modest 1/2.3" CCD sensor, measuring 6.08 x 4.56 mm with a tiny surface area of just 27.72 mm². It captures 12 megapixels, which sounds respectable until you realize its age and technological limits.

The Sony RX100 VII, on the other hand, wields a much larger 1" BSI-CMOS sensor (13.2 x 8.8 mm/116.16 mm²) at 20 megapixels. This significant sensor area difference generally translates into better low light performance, dynamic range, and finer detail capture - especially relevant when pixel-peeping or printing large.

In side-by-side testing under identical conditions, the RX100 VII produces noticeably cleaner images at higher ISOs, with richer colors and better highlight retention. The FS15’s CCD sensor - while reliable for daylight shooting - struggles with noise creeping in as you push beyond ISO 160. Even the max 1600 ISO native limit of the FS15 is somewhat optimistic for usable quality.

I’ve relied on Sony’s 1" sensors for years in various RX100 generations, and their BSI-CMOS rollout is a key reason they deliver excellent tonal gradations and low-light chops. The FS15’s sensor is more of a point-and-shoot relic, best at ISO 80-200 range.

Control Freaks, Rejoice: Design and User Interface

The FS15 keeps things simple with its fixed, non-touch screen and no electronic viewfinder - just a 2.7” LCD with 230k dots. It lacks manual exposure modes, no shutter or aperture priority, and only offers aperture range F3.3-5.9 over its 29-145 mm (5x optical zoom) lens. Autofocus is limited to single point, contrast-detection only, and there’s no face or eye detection.

The RX100 VII upgrades the game with a 3” tilting touchscreen boasting 921k dots, full manual controls including aperture and shutter priority, and a maximum aperture that opens wider at F2.8 at the wide end - great for shallow depth-of-field effects. Plus, the RX100 VII includes a high-res 2.36M dot electronic viewfinder with 100% coverage and 0.59x magnification, markedly superior for composing in bright conditions.

I’ve spent hours shooting with both, and the RX100 VII’s interface feels like a professional tool - quick access dials, customizable buttons, and reliable touch AF - and the presence of a pop-up flash that integrates well with the camera’s exposure matrix is a plus. The FS15’s fixed buttons and menus feel sluggish, and the lack of manual exposure modes makes it unsuitable for creative control - a non-starter for enthusiasts.

Autofocus and Burst: Speed, Accuracy, and Tracking

The FS15’s autofocus system is a humble affair: contrast-detection only with 11 focus points and no face or eye detection. Continuous autofocus and tracking are absent, limiting usability for anything other than static or slow-moving subjects. Its continuous shooting speed clocks at a modest 2 frames per second.

The RX100 VII boasts hybrid autofocus with both phase and contrast-detection, boasting real-time tracking, eye AF for humans and animals, and up to 20 fps continuous shooting - effortlessly capturing fast action.

Having thoroughly tested the RX100 VII in wildlife and sports contexts, I can vouch for its AF performance. The camera locks onto moving subjects quickly, tracks complex motion with minimal focus hunting, and eye detection means portraits and street shots come out sharply focused on the eyes - crucial for professional quality.

Order of magnitude difference here. The FS15 is best suited for landscapes and casual snapshots, while the RX100 VII excels in high-demand autofocus scenarios.

Lens and Zoom Versatility: Reach and Clarity

The FS15’s built-in 29-145 mm equivalent zoom is a 5x optical range with aperture from F3.3 to F5.9. The lens is fine for snapshots but limited in low light and does not deliver notable sharpness by today’s standards.

The RX100 VII pushes 24-200 mm (8.3x zoom) with a faster F2.8-4.5 aperture range, providing greater flexibility for wide-angle landscapes through medium telephoto portraits and wildlife reach. Sony’s high-quality lens optics exhibit crispness and contrast practically edge-to-edge, with minimal distortion and excellent flare control.

From my extensive shooting experience, the RX100 VII’s lens versatility gives it a massive leg up for travel and wildlife photography, while the FS15’s optical compromises make it primarily a casual camera.

Battery Life and Storage: How Long Can You Keep Shooting?

Battery life is often a sticking point on compacts. The FS15’s specs don’t list official battery life, but user reports suggest moderate endurance - typical for earlier ultracompacts. The RX100 VII comes with an NP-BX1 battery rated for about 260 shots per charge, a figure in line with its peers, and more than adequate with spare batteries for day-long shoots.

Both cameras accept SD cards, but the RX100 VII’s support for SDXC and Memory Stick Pro Duo options means better compatibility and higher capacity choices.

Multimedia Capabilities: Video and Connectivity

The FS15 records video maxing out at 848 x 480 (WVGA) at 30 fps in Motion JPEG format - a far cry from modern standards. There is no microphone input or ability to tweak exposure during filming. No wireless connectivity exists; image transfer requires USB 2.0 connection.

Meanwhile, the RX100 VII shoots true 4K UHD (3840 x 2160) at 30fps with superb quality, using efficient professional codecs like XAVC S. It features clean HDMI output, a microphone input for audio quality control, and full HD slow-motion recording. It also offers built-in Wi-Fi, Bluetooth, and NFC - for wireless image transfer and remote control via smartphone apps.

For vloggers, event videographers, and hybrid shooters, the RX100 VII’s video arsenal is a game-changer compared to the FS15’s basic clip capture.
