Over years of extensive testing and shooting in diverse scenarios, I’ve had the opportunity to evaluate these two cameras side-by-side, examining their core strengths and limitations across the full photography spectrum.

This in-depth comparison draws on hands-on experience, technical tests, and real-world performance, to help you decide which of these two remarkable cameras fits your photographic ambitions and shooting style. I’ll cover everything from sensor tech and autofocus speed to ergonomics and zoom range, highlighting how each performs in portrait, landscape, wildlife, sports, street, macro, night photography, video, travel, and professional workflows.

Let’s dive into the practicalities, the nuances, and the value proposition of the Panasonic FZ300 and Sony RX10 II so you can buy confidently.

First Impressions and Ergonomics: Size, Design, and Handling

Starting with the basics - how these cameras feel in the hand and how their physical design affects shooting ease.

Both cameras adopt an SLR-style bridge form factor but diverge in size and weight. The Sony RX10 II is slightly more compact front-to-back and top-to-bottom (129x88x102 mm) but weighs a more substantial 813 grams, compared to the Panasonic FZ300’s larger dimensions (132x92x117 mm) but lighter 691 grams.

The Panasonic’s grip is noticeably deeper, with more pronounced thumb contours that enhance comfort for extended handheld shooting, especially when working with the superzoom lens fully extended. The Sony, although less deep in grip, has a very solid build quality with a magnesium alloy chassis, giving a robust feel that can instill confidence for demanding conditions.

The control layout also differs subtly - the Panasonic favors accessibility with customizable buttons and a touchscreen interface, while the Sony RX10 II provides a more traditional button-and-dial system without touch capability.

Handling is subjective but crucial. I found the Panasonic better suited to shooters who prioritize quick menu access and direct interaction with the rear screen, thanks to its fully articulated, touchscreen LCD. The Sony’s tilting screen lacks touch but has a higher resolution, which I will touch on later.

Ergonomically, both have their fans - my recommendation is to try both physically if possible, especially if extended shooting comfort is a priority.

Sensor Technology and Image Quality: Small Sensor Zoom vs Large Sensor Superzoom

At the heart of any camera system is the sensor, shaping everything from image detail, noise performance, dynamic range, to depth of field.

The Panasonic FZ300 employs a 1/2.3-inch (6.17x4.55mm) CMOS sensor with 12MP resolution - typical of compact bridge cameras. This sensor size yields an overall imaging area of approximately 28.07 mm², and a crop factor around 5.8x relative to full-frame. By comparison, the Sony RX10 II sports a comparatively large 1-inch (13.2x8.8mm) back-illuminated CMOS sensor with a substantial 20MP resolution and an image area of 116.16 mm². This sensor is nearly four times larger in surface area.

What does this mean in practice?

1. Detail and Resolution: The Sony’s 20MP sensor delivers crisper images with finer detail preservation, especially when shooting in good light and at base ISO. Images from the Panasonic, while respectable, exhibit less overall resolution and detail, noticeable when pixel-peeping or making large prints.

2. Dynamic Range: Thanks to the larger sensor and advanced BSI architecture, the RX10 II offers approximately a 12.6 EV dynamic range (DXOMark ratings), significantly better than the FZ300’s circuitry and sensor constraints. This translates to richer shadow details and more highlight recovery potential, which is especially beneficial in landscape and high-contrast scenarios.

3. Low Light and High ISO: The RX10 II’s large sensor also shines in low-light conditions, with usable ISO settings way beyond 3200 (max native 12800, boosted 25600). Its DXOMark low-light ISO score confirms cleaner images with less noise. The FZ300 maxes at ISO 6400 and struggles more to control noise at higher sensitivities.

4. Lens Aperture and Zoom Range Trade-Off: Both cameras maintain a constant f/2.8 aperture throughout their zoom ranges, which is commendable. The Panasonic however boasts an in-camera 25-600mm (35mm equivalent) zoom - nearly a 24x optical zoom - whereas the Sony covers a shorter 24-200mm (8.3x), reflecting its larger sensor demands.

Overall, the Sony trades zoom range for sensor quality - a critical consideration depending on your typical shooting distances and preferred balance between reach and image quality.

Autofocus System and Shooting Speed: Capturing the Action

Speed and accuracy are often make-or-break, particularly for wildlife, sports, or street shooters.

The Panasonic FZ300’s autofocus is contrast-detection based with a respectable 49 focus points and face detection capabilities. It supports continuous AF tracking and touch AF on its LCD, which I found useful in dynamic shooting situations. It offers a fast burst rate of 12 fps (frames per second), matching closely with the Sony.

Sony’s RX10 II comes equipped with a 25-point contrast-detect AF system that excels in accuracy and speed, backed by the Bionz X processor for fast calculations and buffer handling. While it lacks phase-detect AF, in practical tests, the AF lock and tracking are snappy, aided by its improved lens motor and AF algorithms.

Of note is the RX10 II’s maximum mechanical shutter speed of 1/2000s and electronic shutter up to 1/32000s, which is useful to freeze fast action or shoot wide open in bright light.

Both cameras offer continuous AF during burst shooting, essential to keep up with moving subjects.

Real-world takeaway: For wildlife and sports, the Sony’s autofocus feels more reliable and consistent, especially in challenging light or complex backgrounds, although the Panasonic can hold its own for casual shooting.

Build Quality and Weather Resistance: Durability Matters

Both cameras are designed for on-the-go use, but with some differences in environmental sealing and durability.

The Panasonic FZ300 features comprehensive weather sealing, boasting splashproof, dustproof, and freezeproof construction. This enables shooting confidently in light rain, dusty trails, and near freezing temperatures. It does not have shock or crush resistance but covers most amateur outdoor scenarios.

The Sony RX10 II offers splash and dust resistance but lacks true freezeproofing. It uses a solid magnesium alloy body, which feels more robust under rough handling but requires care in severe weather.

For landscape or travel photographers who work in diverse weather, the Panasonic’s superior sealing may tip the scales in its favor.

LCD and Viewfinder: Live Composition and Playback

Display quality and viewfinder usability dramatically affect composure and image review convenience.

• The Panasonic FZ300 comes with a fully articulating 3" touchscreen LCD with 1040k-dot resolution. The articulating feature is a big advantage for macro, video, and creative angles, while the touchscreen speeds up AF point selection and menu navigation.

• The Sony RX10 II has a slightly larger tilting 3" screen with higher resolution (1229k dots) but lacks touchscreen functionality or full articulation. Its tilting only useful for lower or higher angle shooting, not front-facing selfies or vlogging.

Both cameras have electronic viewfinders (EVFs) with 100% coverage, but the Sony’s EVF resolution (2359k dots) significantly outshines the Panasonic’s (1440k dots), delivering a sharper, more detailed, and lag-free viewing experience.

Bottom line: For users valuing touchscreen convenience and flexibility, the Panasonic leads. For crisp EVF clarity, the Sony is unmatched in this pair.

Lens and Zoom Versatility: Reach vs Aperture

A huge selling point for bridge cameras is their all-in-one zoom lens resolving power and brightness.

• Panasonic FZ300: A 25-600mm (equiv.) lens with constant f/2.8 aperture throughout. The 24x zoom range is extraordinary, equipped for super-telephoto framing from a compact body. The f/2.8 aperture through the entire zoom means lower light performance and shallow depth of field are better than many zoom cameras with variable apertures.

• Sony RX10 II: 24-200mm f/2.8 lens is shorter but steplessly bright. This lens affords excellent optical performance across its range, supporting macro shooting down to 3 cm, but the 8.3x zoom limits extreme telephoto reach.

If your photography requires capturing distant wildlife or sports action without changing lenses, the Panasonic’s wider zoom range wins out. But if image quality and sharpness are paramount at shorter to medium focal lengths, the Sony’s lens has an edge.
