Panasonic FZ300 vs Pentax Q-S1: A Detailed Hands-On Comparison for the Discerning Photographer

Choosing between cameras from Panasonic’s superzoom bridge lineup and Pentax’s quirky, compact mirrorless series is no straightforward task - especially when these two models, the Panasonic FZ300 and Pentax Q-S1, serve very different market niches yet share some overlapping capabilities. Over hundreds of hours of rigorous real-world and technical testing, I’ve pitted these two cameras head-to-head across diverse photographic disciplines to present you with a thorough, trustworthy appraisal based on firsthand experience.

Whether you are a hobbyist craving versatility on a limited budget, or a pro seeking a nimble backup, this comparison aims to clarify which camera suits your needs best - cutting through the jargon with practical advice, nuanced insights, and carefully balanced critique.

First Impressions: Handling, Size, and Ergonomics

Even before you lift either camera, their form factors say a lot about their intended user.

The Panasonic FZ300 presents itself as a robust bridge camera with an SLR-like design - measuring 132×92×117 mm and weighing a reassuring 691g including battery. The grip is deep and textured, ideal for extended handheld shooting, especially given the heavy zoom lens. The full physical control suite, including a robust mode dial and dedicated dials for aperture and shutter speed, signals serious photographic intent.

In stark contrast, the Pentax Q-S1 shrinks to a trim 105×58×34 mm and featherweight 203g, adopting a rangefinder-style mirrorless silhouette rather than an SLR form. It’s easy to slip in a coat or jacket pocket. However, the Q-S1’s minimalist approach - particularly the lack of an electronic viewfinder - and smaller control buttons can feel limiting in demanding shooting scenarios.

The FZ300’s size translates to a more confident hold and better balance, especially when using telephoto reach, while the Q-S1’s portability makes it a discreet companion for casual outings and street photography.

Control Layout & User Interface: Precision vs Simplicity

The FZ300 boasts a traditional DSLR-style top panel with well-placed dials for aperture, shutter speed, and exposure compensation, along with a joystick for autofocus point selection. This hardware richness fosters quick adjustments, essential in fast-changing environments.

The Q-S1’s top layout is minimalist - fewer external controls, no dedicated exposure dials. Exposure compensation and modes are accessible primarily through menus. While this design suits casual shooters less inclined to fiddle with settings on the fly, it slows down experienced photographers expecting tactile feedback and fast setting changes.

I appreciate Panasonic’s illuminated buttons (the Q-S1 has none), helping in low-light work. The FZ300’s rear screen is fully articulated and touchscreen-enabled - a boon for video shooters and awkward angle compositions; the Q-S1 sports a standard fixed screen with no touch support, which feels dated.

Speaking of screens…

Displays and Viewfinding: Articulation and Resolution Matter

The FZ300’s 3.0-inch, 1040k-dot fully articulated touchscreen is a standout. This flexibility and clarity not only facilitate creative framing - like vlogging or macro shots - but also enhance usability through touch AF and menu navigation.

Conversely, the Q-S1’s 3.0-inch, 460k-dot fixed screen lacks touch capability and limited resolution restricts clarity, making critical focus evaluation and image review trickier under bright light.

The FZ300 also includes a high-resolution (1440k-dot), 100% coverage electronic viewfinder, giving excellent compositional accuracy and visibility under challenging lighting - something the Q-S1 lacks entirely. Instead, you rely solely on its LCD, which may pose problems in direct sunlight or for photographers accustomed to eye-level composition.

For photography that demands eye-level precision, the FZ300 clearly leads here.

Sensor Technology and Image Quality: Small Sensor vs Larger Sensor

At the heart of any camera is its sensor, and here, the fundamental differences become clear:

• Panasonic FZ300 uses a 1/2.3” CMOS sensor (6.17 x 4.55 mm; 28.07 mm²) - typical for bridge superzooms, prioritizing zoom range and price.
• Pentax Q-S1 sports a larger 1/1.7” BSI-CMOS sensor (7.44 x 5.58 mm; 41.52 mm²) designed for better light gathering and noise performance.

Both cameras offer a 12 MP resolution ceiling (4000×3000 pixels), but sensor size differences profoundly impact dynamic range, noise, and low-light performance.

Testing across ISO sensitivities revealed that the Q-S1 produces cleaner images up to ISO 1600, with more usable detail retention at ISO 3200 and above. The FZ300’s noise becomes apparent at ISO 800, though image stabilization helps mitigate shutter speed challenges.

Pentax’s BSI (back-illuminated) sensor design and lack of an optical low-pass filter give the Q-S1 a slight edge in color depth and sharpness in well-lit scenarios, especially when paired with its sharper prime lenses. However, the FZ300 compensates with a faster fixed lens aperture (constant f/2.8) through its zoom range, an unusual and impressive feature in superzooms.

In practical terms, if your priority is image fidelity and noise control (e.g., portraits or low-light scenes), the Q-S1’s sensor is technically more capable. But if you prize zoom flexibility with reasonable quality, the FZ300 strikes a good balance.

Autofocus System: Speed, Accuracy, and Tracking under Pressure

Both cameras rely on contrast-detection autofocus systems without phase-detection pixels.

• The FZ300 features a 49-point (though exact cross-points unknown) AF system, augmented by touch AF, face detection, continuous AF with tracking, and a speedy AF lock.
• The Q-S1's number of AF points is unspecified but supports face detection, center-weighted AF area, and standard contrast detection AF as well.

In real-world testing - especially with moving subjects - the FZ300’s AF is faster and more consistent, aided by its advanced autofocus algorithms and touch screen point selection. Its continuous AF and tracking keep pace well with wildlife and sports subjects up to moderate speed, supported by a 12 fps burst rate that is quite impressive in this class.

The Q-S1 lags behind in autofocus speed and tracking refinement, with occasional hunting in low light and slower continuous shooting (5 fps). Without an EVF to aid precise focus through the eye, it’s harder to capture fast action or fleeting moments confidently.

Portrait photography benefits from the FZ300’s face detection and eye detection features, which, while basic compared to modern flagships, are reliable and practical for casual and enthusiast-level use.

Lens and Zoom: Fixed Superzoom vs Interchangeable Lens Compact

The most fundamental distinction lies in the lens systems:

• Panasonic FZ300 employs a bright 24x optical zoom fixed lens covering 25–600mm (35mm equivalent) at a constant f/2.8 aperture throughout the zoom range. This is a rare and highly coveted specification in bridge cameras, enabling creative reach without compromising aperture speed for low light and subject isolation.

• Pentax Q-S1 uses the Pentax Q mount with availability of eight native lenses ranging from fisheye to telephoto primes, plus macro options. The sensor crop factor (4.8x) means a 50mm lens behaves like ~240mm equivalent.

For versatility and convenience, the FZ300’s integrated zoom lens is unmatched - ideal for travel, wildlife, and event shooters who dislike swapping lenses but demand reach.

However, the Q-S1’s lens lineup offers flexibility to suit a variety of shooting styles, including dedicated macro and wider aperture primes, albeit at limited telephoto reach and slower apertures on many lenses.

For macro photography, the FZ300’s ability to focus as close as 1cm with its integrated lens is impressive. The Q-S1 depends on specialized macro lenses to achieve comparable results.

Shooting Disciplines: How Do They Perform Across Genres?

I tested both cameras across major photography styles to uncover strengths and weaknesses:

Portraits: Skin Tones and Bokeh

• The Q-S1, with larger sensor and prime lenses, creates subtly more natural skin tones and superior subject-background separation, though limited by generally slower lenses and lack of eye AF.
• The FZ300’s f/2.8 constant aperture at long focal lengths delivers respectable background blur and smooth bokeh with easier framing through zoom flexibility.

In indoor portrait sessions, the Q-S1’s noise control and color rendering edged results slightly, but for casual portraits and outdoors, the FZ300 shows excellent versatility.
