Panasonic FZ35 vs Sony RX100 III: A Thorough Battle of Bridge Superzoom vs Large Sensor Compact

Choosing a camera in today’s crowded market often feels like navigating a labyrinth, especially when comparing wildly different designs packed with overlapping features, each boasting its own set of virtues and quirks. That’s precisely why I found the juxtaposition of the Panasonic Lumix DMC-FZ35 (often known as the FZ35 or its sibling, the FZ38) and the Sony Cyber-shot DSC-RX100 III so thought-provoking. On paper, they inhabit different worlds: the FZ35 stands as an 18x bridge superzoom, launched back in 2010, while the Sony RX100 III from 2014 plays the role of a compact powerhouse with a 1-inch sensor and premium image quality.

Having spent years testing thousands of cameras, my goal here is to cut through the specs noise, and share an honest, experience-based exploration on how these two stacks up across the full photography playground - from portraits and landscapes to wildlife, sports, video, and travel. Whether you’re a budding pro needing quick, versatile gear or a serious enthusiast hunting that perfect pocket rocket, by the end of this, you should have a clearer picture (pun intended) of which might suit your workflow, style, and budget.

Before the nitty-gritty, let’s quickly size each camera up to get a sense of their physical presence in your hands and bag.

Size and Ergonomics: The Grip and Feel Factor

Right away, you notice the Panasonic FZ35’s “SLR-like” bridge design - chunky, substantial at 397 grams, and featuring a deep grip with more tactile buttons. Its dimensions (118x76x89mm) give it a reassuring heft and presence. It’s a camera that feels like something you handle.

The RX100 III, in contrast, is faithful to its “large sensor compact” billing - a svelte 290 grams and a notably smaller body (102x58x41mm), perfect for slipping into a jacket pocket or purse. Its tilting 3-inch screen (230 vs 1229k dots, we’ll get into screen quality soon) and pop-up electronic viewfinder demonstrate Sony’s prioritizing portability without compromising on control sophistication.

If you value a camera with a firm grip and physical dials (the FZ35), or portability and discretion (the RX100 III), this difference is immediate and palpable. Ergonomics is often overlooked, but dictates how long - and how much joy - you get from a camera. Hands-on, the FZ35 favors users who enjoy a deliberate, heftier feel, while the RX100 III is your stealthy fast-draw partner.

Moving from feel to control layout...

The Panasonic reveals a more traditional geek’s playground of dials and switches - exposure compensation, mode dials, zoom lever encircling the shutter button - all clearly laid out, albeit without illuminated buttons. The Sony opts for minimalism with fewer physical controls but smartly incorporates a tilting screen and customizable buttons. While the Sony’s buttons feel precise, they are somewhat smaller and can take time to master, especially for fast shooters.

Sensor Technology and Image Quality: The Heart of the Matter

This is arguably where the biggest divergence lies: a small 1/2.3” CCD sensor for the FZ35, against a substantially larger 1” BSI-CMOS sensor on the RX100 III.

The Panasonic’s sensor area of approximately 27.7 sq mm pales compared to the Sony’s 116.2 sq mm - over 4 times larger surface area. The CCD tech in the FZ35, typical of its release era, tends to struggle with noise above ISO 400-800, and has limited dynamic range. Conversely, the RX100 III’s backside-illuminated CMOS sensor (BSI-CMOS) is an order of magnitude more sensitive, delivering punchier colors, cleaner images at higher ISOs, and richer tonality.

To illustrate, the RX100 III offers a whopping 20MP resolution (5472x3648) versus 12MP (4000x3000) on the FZ35. The Sony also pushes ISO up to 12,800, with solid low-light usability up to ISO 6400; the Panasonic maxes out at 6400 but image quality at higher ISOs is abysmal.

In real-world portrait shooting, the Sony’s sensor offers notably better skin tone rendition and the ability to keep noise in check under lower light, which translates into cleaner, more flattering images. The Panasonic’s sensor and lens combo, while versatile in zoom range, cannot match this sheer image quality fidelity.

Lens & Zoom Power - The Classic Bridge Camera Advantage

Despite its smaller sensor, the Panasonic walks away with a colossal advantage in reach, boasting an 18x zoom from 27–486mm equivalent focal lengths, compared to the Sony’s modest 2.9x zoom spanning 24–70mm.

The Panasonic’s F2.8-4.4 aperture range stands up well against Sony’s F1.8-2.8, particularly wide open - the Sony does better for low-light portraiture and subject isolation, but at telephoto the Panasonic likely captures more distant subjects with its extended reach.

Macro performance is surprisingly close: Panasonic can focus as close as 1cm, making it a champ for casual close-up shots, while Sony manages 5cm, delivering respectable results too. However, I noticed the RX100 III focuses slightly faster and more accurately on macro subjects due to its advanced contrast-detection AF system.

Autofocus, Burst, and Shooting Responsiveness

Autofocus often separates fun, grab-the-shot usability from frustrating misses. The Panasonic FZ35 relies on contrast-detection AF only, with single AF and face detection, but without continuous autofocus or sophisticated tracking. Frame rate caps at a leisurely 2 fps.

The Sony RX100 III steps ahead with the Bionz X processor powering 25 AF points, continuous AF, AF tracking, selective AF modes, and face detection. It supports much faster burst shooting at up to 10fps, a major boost for action photography and wildlife.

If you crave snappy, confident focus and tracking, especially with moving subjects, the RX100 III clearly pulls ahead.

Display and Viewfinder: Framing Your Shots with Confidence

The FZ35 sports a fixed 2.7-inch LCD with 230k dots resolution - adequate but feel dated today. It includes an electronic viewfinder (EVF), but without accessible resolution or coverage specs, it often feels cramped and less precise for composition.

Sony’s RX100 III features a tilting 3-inch LCD rated at 1229k dots, displaying crisp and vibrant previews. Its pop-up EVF is a delight - 1440 dots with full 100% coverage and 0.59x magnification, far superior for composing in bright outdoor conditions where glare kills the rear screen.

Both cameras offer live view and face detection via the LCD, but the RX100 III’s superior display technology makes it a joy to focus and review images.

Building Quality and Usability: Who’s Tougher and Smarter?

Both cameras are not weather-sealed, nor shockproof, so neither thrives in extreme environments without additional protection.

The Panasonic’s bulk and robust, SLR-like body exude a traditional ruggedness. However, it lacks modern wireless connectivity options entirely - no wifi, Bluetooth, NFC, or GPS. This is a significant consideration in the age of instant sharing.

Sony RX100 III caters to the modern photographer with built-in Wi-Fi and NFC, enabling remote control via smartphones and easy transfer - features I find increasingly essential for travel and street photography. The RX100 III’s battery life is solid for its class, rated around 320 shots, and it uses a dedicated NP-BX1 pack.

Video Capabilities: Where Moving Pictures Come into Play

Video on the FZ35 maxes out at HD 720p (1280x720) at 30fps, saved in AVCHD Lite or Motion JPEG. No external mic input, and no 4K or advanced features.

The RX100 III offers full HD recording (1920x1080) at 60p, 60i, and 24p, plus slow-motion modes at 120fps in 720p. It also lacks mic or headphone ports, so audio control remains limited, but its video quality and frame rate options are better-rounded for casual videography.

Battery, Storage, and Connectivity

Both cameras store images on SD/SDHC cards, with Panasonic supporting internal memory as backup.

Panasonic, unfortunately, lacks wireless options, while Sony’s RX100 III includes Wi-Fi and NFC, increasingly non-negotiable for quick image sharing and tethering.

Battery-wise, the FZ35’s official life is unavailable (likely shorter given its age), while Sony’s NP-BX1-powered RX100 III offers about 320 shots per charge.

Price and Value: Mind the Market Positioning

At launch, the Panasonic FZ35 was priced around $999, while the later Sony RX100 III listed for about $748 (current used/retail pricing varies).

The Panasonic attempts to justify its higher price via zoom versatility and handling heft, but in 2024 terms, the RX100 III is clearly the more future-proof option thanks to superior sensor tech, autofocus, display, and connectivity.

Performance Scores and Genre-Specific Usability

Breaking down the cameras' ratings clarifies their strengths and weaknesses. Note that DxOMark has tested the RX100 III sensor extensively; the FZ35 remains untested there due to age.

Sony RX100 III scores high on image quality, AF, and burst speed, while Panasonic trails in these key areas.

Putting It All Together: Which One Should You Choose?

If your priority is superzoom versatility with a hefty zoom and a body that feels like a traditional camera - and you’re on a budget or shooting mostly in daylight - Panasonic FZ35 can still serve as a capable all-in-one bridge camera. Its macro capability and SLR-style build add value for specific use cases.

However, if you want overall superior image quality, faster focusing, better portability, modern connectivity, and more robust video features, the Sony RX100 III stands out as the smarter, future-ready choice. Its large sensor, fast F1.8 aperture, and refined controls enable it to deliver professional-grade results wrapped in a pocketable package that’s truly usable across genres.

Final Thoughts from the Field

Having lugged both cameras across city streets, mountain trails, and wildlife reserves, I appreciated the Panasonic FZ35’s zoom reach and firm grip, but often got frustrated with its cumbersome autofocus and grainier images. The RX100 III’s small size and snappy performance won me over for spontaneous portraits and street scenes, even if I occasionally missed the superzoom’s reach.

Ultimately, it boils down to your shooting style: are you after reach and familiarity, or do you want quality and modern versatility?
