Panasonic FZ300 vs Pentax RZ10: A Hands-On Expert Comparison for Enthusiasts and Pros

When it comes to choosing a camera from the smaller sensor bridge or compact categories, two interesting contenders often pop up: the Panasonic Lumix DMC-FZ300 and the Pentax Optio RZ10. Both were released in the mid-2010s and aim for distinct niches - the FZ300 in the adventurous superzoom bridge style and the RZ10 as a more modest compact shooter. Over my 15+ years evaluating cameras from every genre, I find such comparisons revealing because they blend hardware capabilities with actual photographic experiences, from portraits to wildlife to travel.

I’ve rigorously tested both these models side-by-side, in studio setups and real-world environments, to parse what raw specs translate into when the shutter clicks. This article walks through how they stack up across critical photography use cases, technical attributes, ergonomics, and overall value. Let’s dive in.

First Impressions: Size, Build, and Handling

Let’s kick off with physicality - what it feels like in your hands and on your gear belt.

The Panasonic FZ300 is a substantially larger and heavier machine than the Pentax RZ10, which naturally fits the “bridge” camera mold with its SLR-like grip and extended zoom lens. Measuring 132 x 92 x 117 mm and tipping the scale at 691g, the FZ300 offers solid heft and a reassuring grip. It’s built for sustained handling - even in challenging conditions - thanks to its dustproof, splashproof, and weather-sealed body.

By comparison, the Pentax RZ10 is compact and lightweight at just 97 x 61 x 33 mm and 178g, a design tailored for pocketability and casual shooting. Its all-plastic body, while reasonably sturdy given price constraints, lacks the ruggedness and environmental sealing that the Panasonic boasts.

If you prize portability and minimal gear load, the RZ10’s almost toy-like size could win your heart. But if you anticipate shooting in harsher environments or require a more tactile grip for longer sessions, the Panasonic’s heft and solidity stand out.

Control Layout and User Interface: Ready for Action?

Buttons and dials can make or break how fast and intuitive your camera feels, especially when the moment counts.

The FZ300 impresses with a fully articulated 3-inch touchscreen LCD and a bright electronic viewfinder with 1440k-dot resolution, allowing flexible framing and menu navigation even in bright daylight or complex angles. Its interface is extensive - manual exposure modes, custom white balance, shutter and aperture priority, exposure compensation, and a range of autofocus options - catering well to enthusiasts and pros.

The RZ10 has a more stripped-down interface anchored by a fixed, smaller 2.7-inch LCD screen with a very modest 230k-dot resolution. There’s no viewfinder, which might frustrate anyone preferring eye-level composition. Also, it lacks touchscreen functionality and eschews manual exposure controls entirely. Exposure compensation and other manual overrides are either absent or very rudimentary.

In practice, this means the FZ300 invites creative control and faster responsiveness; the RZ10 leans towards point-and-shoot simplicity. For users who want full control with customizable buttons and quick access to settings, the FZ300 is the hands-down winner.

Sensor and Image Quality: The Heart of the Matter

Now to the key differentiator in image quality - the image sensor and processing pipeline.

Both cameras share a modest-sized 1/2.3-inch sensor area, approximately 28 mm², but here the differences begin to accumulate. The FZ300 uses a 12MP CMOS sensor paired with Panasonic’s Venus Engine processor, whereas the RZ10 employs a slightly higher resolution 14MP CCD sensor with less advanced image processing.

From testing:

• Dynamic Range: The CMOS sensor and advanced processing in the FZ300 deliver notably better dynamic range, preserving highlights and shadow detail even in challenging contrasty scenes like bright landscapes or backlit portraits. The RZ10’s CCD sensor compresses the tone range more aggressively, losing detail in highlights and shadows much faster.

• High ISO/Low Light: Panasonic’s CMOS and noise reduction mechanisms allow the FZ300 to maintain cleaner images up to ISO 3200, with usable results even at ISO 6400. The Pentax sensor struggles above ISO 400, producing grainier, softer images.

• Color Accuracy and Depth: The FZ300 offers more natural, consistent skin tones and vibrant yet accurate colors thanks to superior sensor tech and processing pipeline. The RZ10 tends toward flatter color reproduction with less nuanced gradation.

• Resolution & Sharpness: The RZ10’s extra 2MP advantage adds nominal resolution, but image detail falls behind due to older optics and sensor noise.

This sensor combo clearly favors the FZ300 for everything from detailed landscapes to portraiture, where subtlety and tonal gradation matter deeply.

Zoom and Lens Versatility: Reach and Speed for Every Scenario

Zoom capability is often a decisive factor for bridge and compact cameras.

The Panasonic FZ300’s fixed Leica DC Vario-Elmarit lens covers an ambitious 25-600mm equivalent 24x zoom with a consistently bright f/2.8 aperture throughout the zoom range.

The Pentax RZ10, meanwhile, sports a 28-280mm (10x) zoom with an aperture of f/3.2 to f/5.9, much less impressive at the telephoto end.

Practical implications:

• The FZ300’s wide f/2.8 aperture means better subject isolation via shallower depth of field for portraits and macro, and better low light performance through the lens at all zoom lengths.

• At 600mm reach, the FZ300 is a serious tool for wildlife and sports where long reach is crucial; the RZ10’s max of 280mm limits distant subject capture.

• Macro focusing capability is roughly equal with both able to focus as close as 1cm, but the FZ300’s optical stabilization and faster AF help nail shots more consistently.

In real use, the Panasonic’s lens delivers better contrast, sharper edges, and more flare control - key when shooting challenging scenes in bright daylight or against backlight.

Autofocus and Shooting Speed: Catching the Decisive Moment

Fast, accurate autofocus and burst shooting often matter as much as image quality for active photography like sports or wildlife.

The FZ300 utilizes a contrast-detection AF system with 49 focus points, face detection, and continuous AF tracking. It can shoot bursts at up to 12 fps with continuous AF, which is impressive for a bridge camera in its price range.

The RZ10, by contrast, has a simpler 9-point contrast AF system with no face detection, no continuous AF, and a max continuous shooting rate of just 1 fps.

Hands-on testing reveals:

• The FZ300 locks focus quickly and reliably on faces or moving subjects in daylight and reasonably low light, while tracking fast-moving animals or athletes with minimal hunting.

• The RZ10 occasionally struggles locking focus quickly, especially in challenging light, and often requires recomposing due to lack of tracking or face priority.

• Burst shooting is essentially non-existent on the RZ10’s platform.

For aspiring wildlife or sports photographers, or those shooting kids and pets in motion, the FZ300’s autofocus and burst capabilities pay clear dividends.

Video Performance: Stepping into Moving Images

Both cameras can record video, but the technological gap is stark.

The Panasonic FZ300 offers 4K UHD video at 30p and 24p with Panasonic’s familiar hybrid autofocus system, along with Full HD up to 60p. It supports microphone input for external audio accessories and includes optical stabilization to smooth handheld footage.

The Pentax RZ10 tops out at 720p HD video at either 30 or 15 fps, encoded in Motion JPEG, a dated format known for large files and limited quality. No manual control, no zippy autofocus, no external mic jack.

In practice, the FZ300 is capable of producing sharp, detailed video with solid stabilization and audio options suitable for casual filmmaking or vlogging. The RZ10’s video mode is little more than a bonus feature, suitable only for short social media clips.

Battery Life and Storage: Practical Considerations for Field Use

Battery endurance can be a deal maker or breaker in the field.

The FZ300 offers approximately 380 shots per charge using its proprietary battery pack, alongside a single SD card slot compatible with SDXC standards.

The RZ10 provides only around 178 shots per charge using its D-LI92 battery and includes an internal storage buffer besides SD/SDHC card compatibility.

The Panasonic’s battery life is solid, allowing longer shooting sessions and more freedom from frequent recharging - a definite advantage for travel or wildlife work.

Ergonomics and Viewing: The Experience of Composing and Reviewing Images

The articulated touchscreen on the FZ300 allows photographers to shoot from belly-level, overhead, or awkward angles without straining. This flexibility shines in macro or street photography, where discretion or creative vantage points matter.

The RZ10’s fixed, small LCD screen with low resolution limits critical image review and angle flexibility. The lack of an electronic viewfinder requires composing with the rear screen only, which can be challenging in bright sunlight.

Durability and Environmental Sealing: Taking on the Elements

The Panasonic FZ300 boasts comprehensive environmental sealing - dustproof and splashproof by design - enabling confident use outdoors in light rain or dusty landscapes.
