As a photography equipment reviewer with over 15 years of extensive hands-on testing - covering everything from sensor performance metrics to field reliability - I provide a meticulous, in-depth comparative analysis of these two models that can empower you to make an informed choice according to your photographic priorities.

A Close Look at Build and Ergonomics: Which Feels More At Home in Your Hands?

Both the Panasonic FZ300 and Sony HX300 adopt a bulky, SLR-style bridge camera form factor aimed at maximizing grip comfort and control access given their long-zoom lens assemblies. The Panasonic measures roughly 132 x 92 x 117 mm and weighs 691 grams, whereas the Sony is a touch more compact in width and depth (130 x 103 x 93 mm) and lighter at 623 grams. The Panasonic’s slightly larger depth is primarily due to its weather-sealed construction and optical design, instilling a sense of robustness absent in the unsealed Sony.

In terms of ergonomics, the FZ300’s heavily textured grip and well-spaced, tactile buttons - with added rear joystick for AF point selection - offer a more refined user experience for extended shooting sessions, especially in demanding weather conditions. The Sony HX300’s controls are intuitive but less sophisticated, featuring fewer dedicated controls and a more modest button layout.

Therefore, photographers planning rugged outdoor shooting or long expeditions will appreciate the Panasonic’s build and handling advantages, while casual users may find the Sony’s marginally lighter footprint easier for carry-around types.

Sensor Specifications & Image Quality: The Heart of the Matter

The Panasonic FZ300 and Sony HX300 both rely on small 1/2.3" CMOS sensors with comparable physical dimensions (Panasonic: 6.17 x 4.55 mm; Sony: 6.16 x 4.62 mm), but their sensor resolutions diverge considerably. The FZ300 has a 12MP resolution optimized for cleaner low-light performance and larger pixel pitch, whereas the HX300 boasts a higher 20MP resolution targeting finer detail capture at the expense of potentially increased noise, especially in dim conditions.

While the inherent limitations of small-sensor superzoom cameras mean that neither will rival APS-C or full-frame cameras in dynamic range or noise control, the Panasonic’s lower megapixel count generally results in better noise handling and superior high-ISO usability up to ISO 6400 native. Sony extends native sensitivity up to ISO 12800 but with trade-offs in noise and detail loss.

Additionally, Panasonic’s sensor incorporates a traditional anti-aliasing filter for reduced moiré artifacts, whereas both models use similar Bayer filters without any phase-detection autofocus pixels (AF relies on contrast detection).

In practical terms, testing confirms the Panasonic FZ300 produces cleaner images in low light, with more faithful color reproduction and less aggressive noise reduction, a boon particularly for landscape and indoor event photography. The Sony HX300, despite its higher resolution, struggles with noise at ISO 800 and above, hampering usability in shadow-heavy or night scenes.

Lens Systems and Zoom Capabilities: Depth and Reach Differ Substantially

Bridge cameras live or die by their zoom lenses. The Sony HX300 offers a remarkable 24-1200 mm (50x) zoom range at a variable aperture of f/2.8-6.3, catering to users prioritizing extreme telephoto reach for wildlife or distant sports action. Conversely, the Panasonic FZ300’s zoom is more conservative, 25-600 mm (24x) at a constant, bright f/2.8 aperture - a rarity in this class that vastly improves low-light performance and background separation throughout the zoom range.

The constant aperture of the Panasonic lens means exposure settings remain stable when zooming, enhancing both still and video shooting consistency. Moreover, the wider aperture is advantageous for subject isolation (think portraits with smooth bokeh) and enables faster shutter speeds in dim environments, limiting motion blur.

Sony’s lens excels at maximum telephoto reach, but the narrower aperture at longer focal lengths (f/6.3) requires higher ISO settings or slower shutter speeds, increasing the risk of noise and blur. Optically, Panasonic’s lens also features macro focusing down to 1 cm, enabling impressive close-up flexibility; Sony does not specify macro performance, limiting versatility for macro enthusiasts.

This emphasis on optical speed and versatility in the FZ300 greatly benefits portrait, low-light indoor, and macro shooters, whereas the HX300 is geared more to distant wildlife, sports, and surveillance scenarios.

Autofocus Performance and Focusing Technologies Compared

Autofocus (AF) systems in bridge cameras often remain a compromise given the lack of hybrid phase detection. The Panasonic Lumix FZ300 incorporates a 49-point contrast-detection AF system with face detection and touch focus, capable of continuous AF in video and stills. It offers impressive AF tracking performance and responsiveness for a camera of its category, supporting AF with touch to select focus points on its touch screen.

The Sony HX300 operates a much simpler AF system with only 9 AF points, also contrast detection but no face or touch AF. Consequently, autofocus speeds and tracking capabilities are noticeably slower and less reliable, especially with moving subjects.

During burst shooting, the Panasonic’s 12 fps continuous shooting combined with AF tracking outperforms the Sony’s 10 fps fixed-focus burst, making the FZ300 a better tool for wildlife and sports photographers needing to freeze action.

LCD Screens and Electronic Viewfinders: Crucial for Composition and Review

A camera’s interface directly impacts intuitive use. Panasonic’s FZ300 boasts a 3-inch fully articulated touchscreen with a sharp 1040k dot resolution, facilitating over-the-shoulder and low-angle shooting. The touchscreen also simplifies focusing adjustments and menu navigation - something advanced users appreciate for speed and convenience.

Sony’s HX300 sports a 3-inch tilting LCD with a slightly lower 921k dot resolution, no touchscreen, and a more ordinary tilting mechanism that limits angles for creative compositions.

Both cameras use electronic viewfinders (EVF); Panasonic’s EVF delivers a crisp 1440k dot resolution with 100% coverage, providing excellent eye-level framing and manual focusing aid through peaking. Sony’s EVF details are unspecified but generally less detailed based on precedent models.

For precise framing and shooting in bright conditions, the Panasonic’s superior LCD flexibility and higher-resolution EVF are distinct advantages, especially for video creators and adventurous still photographers.

Image Stabilization Systems: Keeping Shots Sharp on the Go

Both cameras include optical image stabilization (OIS) systems within their lens assemblies, essential for countering handshake - particularly crucial given their extensive zoom ranges.

The Panasonic FZ300 features an OIS system optimized for steady handheld shooting at longer focal lengths and supports in-body stabilization synergy with post-focus capabilities for sharper close-ups. The Sony HX300’s optical stabilization is effective but slightly less refined; subjective testing reveals a tad more sensitivity to vibration at the extreme end of the zoom range.

For video, Panasonic’s OIS performs notably better, providing smoother footage and minimizing jitter without external stabilization rigs. This makes the FZ300 more suitable for handheld 4K video capture.

Video Capabilities: A Clear Winner Emerges

A decisive differentiator is video functionality. The Panasonic FZ300 supports 4K UHD video recording at 30p and 24p, with MPEG-4 and AVCHD codecs, microphone input for external audio, and advanced framing features like 4K Photo mode (extracting 8MP stills from 4K footage). Additionally, it offers timelapse recording and post-focus technology - showcasing Panasonic’s forward-thinking video/hybrid design.

The Sony HX300, meanwhile, records only Full HD 1080p video at 60 and 50 fps with unspecified but proprietary video formats and no microphone input. It lacks 4K capture and video-centric features like focus peaking or advanced exposure controls.

For multimedia creators, vloggers, or hybrid shooters requiring high-quality 4K capturing and creative control, the Panasonic FZ300 is an unequivocal choice. The Sony HX300 caters to more casual videographers satisfied with HD video and straightforward operation.

Battery Life and Portability: Who Keeps Shooting Longer?

The Panasonic FZ300 comes with a rechargeable battery pack rated for approximately 380 shots per charge, consistent with typical bridge models featuring electronic viewfinding and large zoom lenses. The Sony HX300 lacks published official battery life data but generally offers similar or slightly shorter endurance due to its older design and smaller battery capacity.

Neither camera is particularly pocketable due to their extensive zoom lenses and SLR-style dimensions; however, the Panasonic’s weather sealing and robust construction justify the bulk for travel and outdoor use, while the Sony’s lightweight build benefits discreet carry.
