Canon PowerShot SX420 IS vs Panasonic Lumix DMC-FZ300: An Expert’s In-Depth Superzoom Showdown
When you’re hunting for a small-sensor superzoom camera, the choice often boils down to balancing reach, image quality, features, and price. Canon’s PowerShot SX420 IS and Panasonic’s Lumix FZ300, both announced in mid-2010s, emerge as compelling contenders in this popular bridge camera segment. However, to simply skim specs tables is to miss the meaningful differences – nuances that make one camera excel in portraiture or another shine in wildlife.
Having logged many hours with both, in varied shooting conditions and photographic genres, I’ll walk you through their true capabilities, strengths, and compromises. This head-to-head comparison cuts through marketing buzz and pixel peeping. By the end, you’ll understand which might suit your photographic style and expectations, whether you’re an enthusiast on a budget or a pro needing a reliable “do-it-all” zoom.
First Impressions: Size, Ergonomics, and Handling
Let’s start with the tactile experience that directly affects your shooting comfort and operational fluency. Both cameras sport an SLR-like bridge camera body, but there are significant differences in size and weight that influence handheld shooting, especially on extended outings.
The Canon SX420 IS is notably compact and lightweight at 325 grams with dimensions of roughly 104x69x85 mm. Its pocket-friendly footprint makes it an easy grab-and-go option for casual travel or street photography when discretion is key. The plastic body feels modest but not flimsy enough to interfere with confidence during casual use.
In contrast, the Panasonic FZ300 tips the scales at 691 grams and measures 132x92x117 mm – substantially larger and heavier. This heft isn’t a burden; it’s a sign of Panasonic’s commitment to ruggedness and handling. The FZ300’s weather-sealed chassis, with true dust and splash resistance, is built for demanding environments, extending shooting possibilities into rain, light snow, or dusty trails. Ergonomically, the FZ300’s grip is firm and curvaceous, offering a more secure hold that pays dividends during telephoto bursts or macro work.
If you prioritize pocketability and light packing, the Canon’s size is a clear advantage. But if you crave a camera that feels substantial, stable, and ready for rougher conditions, Panasonic’s physical stature embodies that professional ruggedness.
Control Layout and Interface: Immediate Usability
Because speed and intuitiveness can make or break the shooting experience, I spent time evaluating how logically each camera’s buttons, dials, and menus are arranged.
The FZ300’s thoughtfully designed top plate and rear interface put most vital controls within thumb reach. It has a traditional mode dial supporting full manual, aperture, and shutter priority modes – an absolute must for photographers who want creative exposure control, quick ISO adjustments, or bracketing options. Touchscreen functionality combined with a fully articulating LCD offers flexibility in composition angles and swipe navigation, which is impressively responsive and smooth.
On the other hand, the Canon SX420 IS is intentionally simplified, offering no aperture or shutter priority mode, and essentially an “auto-everything” experience with minimal manual override. Its fixed screen lacks touch capabilities and articulation, and lacks an electronic viewfinder altogether, demanding more reliance on the LCD - which, as we’ll see shortly, is also a few steps behind in quality. The control layout can feel basic and somewhat cramped in the absence of dedicated dials or external buttons.
For photographers who relish manual control, quick adjustments, and tactile feedback, Panasonic is clearly superior. Canon might appeal more to beginners or those who prefer point-and-shoot simplicity.
Sensor and Image Quality: The Heart of the Matter
Both cameras employ the same sensor size: a 1/2.3” type measuring approximately 6.17 x 4.55 mm, with a sensor area of 28.07 mm², placing them firmly in the small sensor superzoom category.
Canon’s SX420 IS packs a 20-megapixel CCD sensor, the higher resolution seemingly promising fine detail. However, CCD sensors in small-sensor compacts tend to have more noise at higher ISO and limited dynamic range compared to CMOS alternatives. In practical use, image files from the SX420 are reasonably sharp in strong daylight but struggle in low-light scenarios beyond ISO 400. Colors are vibrant but sometimes oversaturated, particularly reds and blues, which might not satisfy critical portrait shooters seeking natural skin tones.
Panasonic’s FZ300 features a 12-megapixel CMOS sensor paired with the powerful Venus Engine processor. This CMOS sensor excels in better noise control, wider dynamic range, and improved color accuracy, particularly at elevated ISO. While the megapixel count is lower, pixel-level sharpness remains excellent thanks to larger effective pixel size, reducing noise and retaining details. The maximum native ISO extends up to 6400, enabling workable images under dim conditions without excessive grain.
In side-by-side comparisons, I appreciated Panasonic’s superior handling of shadows and highlights, critical when shooting landscapes or events with challenging lighting. Meanwhile, the Canon sometimes produced harsher noise and banding relatively early, limiting its usability in detail-critical workflows.
Overall, if image quality - particularly in mixed lighting - is paramount, the Panasonic FZ300’s CMOS sensor and processing pipeline lead the way.
Display and Viewfinder: Composition and Usability
Shooting without a reliable display or viewfinder is a non-starter for serious photographic work, especially outdoors where bright light complicates LCD use.
Here, our two cameras diverge dramatically.
The Canon SX420 IS employs a fixed 3-inch LCD with just 230k dots, which is quite low resolution even by mid-2010s standards. Without touchscreen, changing settings involves clumsy button presses navigating small menus, and the non-articulated screen hampers creative shooting angles. Outdoors, visibility is mediocre, and the lack of any form of viewfinder forces you to wrestle with glare.
By contrast, the Panasonic FZ300’s 3-inch, 1040k-dot fully articulated touchscreen delivers sharp, vibrant views and immense flexibility - ideal for macro low angles or vlogging. The touchscreen interface is fast, intuitive, and supports tap-to-focus and menu navigation, speeding up shooting workflow significantly.
Adding to this, the FZ300 incorporates a high-resolution electronic viewfinder (EVF) with 1440k-dot resolution, 100% coverage, and good refresh rates. This EVF is invaluable when shooting in bright sunlight or for steady handheld framing at long telephoto ranges. The Canon offers no EVF, making the FZ300 far more versatile for composition-intensive work.
For anyone prioritizing framing accuracy, especially in bright conditions or moving subjects, the Panasonic optics here are game-changing.
Lens Performance and Aperture Range: Zoom Versatility and Image Control
The defining feature of these two superzooms is their lens specs – specifically how zoom range, aperture, and optical performance interplay.
Canon SX420 IS:
- Zoom range: 24-1008 mm equivalent (42x optical zoom)
- Maximum aperture: f/3.5–6.6
Panasonic FZ300:
- Zoom range: 25-600 mm equivalent (24x optical zoom)
- Maximum aperture: constant f/2.8
The Canon SX420 IS boasts an impressively long 1008 mm telephoto reach, unmatched in this comparison for wildlife or distant subjects. However, that advantage comes with optical compromises. Its smaller maximum aperture slows to f/6.6 at the long end, limiting light intake and affecting autofocus performance and low-light usability. Image quality at full zoom, while surprisingly decent for a compact sensor camera, exhibits the expected softness and chromatic aberration issues typical for extreme zoom glass.
Conversely, the Panasonic FZ300’s lens sacrifices some telephoto reach for a constant, bright f/2.8 aperture across the entire zoom range. This is a significant advantage for low-light shooting - street, indoor sports, or astro shots - as well as for producing smoother bokeh and better subject isolation at wider angles. Panasonic’s optics deliver sharpness edge-to-edge with minimal distortion or flare, as tested in real scenes.
Meanwhile, the FZ300 lens supports macro focusing down to 1cm, far superior to the Canon’s "0cm" macro spec (which logically means no close focus function). This broadens creative possibilities without attachments.
While the Canon is the “longest reach” champion, the Panasonic’s brighter and steadier lens makes it a more accommodating “all-round” zoom capable of performing better under diverse conditions.
Autofocus Systems: Speed, Accuracy, and Tracking
Extensive autofocus testing reveals the vast gulf between these cameras’ focusing technologies and thus their practical usability across genres.
Canon SX420 IS has a contrast-detection AF system with face detection but without AF tracking or phase detection, and no dedicated focus points count is provided. Its autofocus performance, while adequate for static scenes, is sluggish with a half-frame per second continuous shooting speed, hampering sports or wildlife capture.
The Panasonic FZ300’s autofocus boasts 49 contrast-detection AF points complemented by face detection and tracking features. This system offers fast, snappy focus acquisition - especially impressive given the small sensor design - and reliable continuous AF during bursts running at 12 fps. When tracking moving subjects in wildlife or sports, the FZ300 maintains lock impressively well.
In practical field tests, the FZ300’s autofocus-derived advantages meant more keeper shots in chasing fast-moving subjects. The Canon’s autofocus lag coupled with lower burst rates made action capture frustrating.
So autofocus performance clearly favors the Panasonic - notably important for handheld action or wildlife photography.
Burst Shooting and Shutter: Catch The Moment
It’s no surprise the FZ300 shoots up to 12 frames per second continuously, a spec more common to enthusiast and prosumer cameras, capped by a shutter speed ranging up to 1/16,000 sec (though the max lowest shutter is 60 sec). This accommodates action sequences and high-ISO speed, including freezing fast motion in bright light.
The Canon lags at 0.5 fps with a max shutter speed of 1/4000 sec, quite similar to entry-level point-and-shoots. This limitation severely hinders spontaneous photography requiring rapid frame grabs or exposure control in bright settings.
Hence, sports photographers and wildlife shooters will find the FZ300 far more capable for tracking and capturing dynamic sequences.
Build Quality and Environmental Resistance: Ready for the Field?
The FZ300’s magnesium alloy body features dustproof, splashproof (weather sealed) construction, a feature rare in this class and price range. It stands up to unpredictable weather and rougher outdoor conditions, making it trustworthy as a travel or adventure camera. A solid warranty and Panasonic’s premium assembly underpin this reliability.
Canon’s SX420 IS lacks any environmental sealing - no dust, water, or shockproofing - significantly limiting its use outdoors in adverse condition scenarios.
If you shoot landscapes, wildlife, or travel where conditions are variable, the Panasonic’s durability tips the scales substantially.
Specialized Use Cases: How Do They Stack Up?
