Canon SX20 IS vs Panasonic Lumix FZ70: A Hands-On Deep Dive Into Two Superzoom Bridge Cameras

When it comes to small sensor superzoom cameras - affectionately called “bridge cams” because they bridge the gap between basic compacts and full-on DSLRs - two models often come up for debate among enthusiasts hunting versatile, affordable gear: Canon’s 2010 PowerShot SX20 IS and Panasonic’s 2013 Lumix DMC-FZ70. Both present intriguing propositions, packing massive zooms and DSLR-style ergonomics into a relatively compact, one-piece design.

I’ve tested both extensively across a variety of disciplines, running them through my usual gauntlet of real-world shooting sessions, lab-style technical checks, and side-by-side field trials. Underneath the specs and marketing hype lie some meaningful differences that will influence your purchase decision based on style, discipline, and budget.

So, grab your favorite brew - let’s dissect these two bridge giants and find out which suits your photographic ambitions best.

First Impressions: Size, Feel, and Handling

The Canon SX20 IS and Panasonic FZ70 share that hefty, SLR-like body architecture characteristic of bridge cameras. But the devil’s in the millimeters and grams: the SX20 measures 128 x 88 x 87 mm and weighs 600g, whereas the FZ70 is a touch larger at 130 x 97 x 118 mm and a smidge heavier at 606g.

Handling wise, both feel sturdy with sizeable grips conducive to comfortable one- or two-handed shooting over extended periods. The Canon’s body is slightly more compact - a boon for travel and street photographers seeking discretion - whereas the FZ70’s somewhat chunkier frame actually translates to a more commanding grip, especially when shooting long telephoto.

Looking at the top panel controls (which I’ll show you shortly), both cameras provide good tactile buttons and dials, but the Canon has the advantage of a fully articulated 2.5-inch screen, offering much more flexibility when tackling creative angles and video work. The Panasonic’s 3-inch screen, while fixed, boasts double the resolution, delivering a far sharper preview and menu navigation experience.

Ergonomics ultimately boil down to personal preference, but I found myself more at home with the Canon’s versatile screen and a slightly neater grip. Still, with either in hand, you’ll enjoy a DSLR-ish shooting feel without breaking the bank.

Sensor and Image Quality: The Heart of the Matter

Both cameras deploy the standard 1/2.3-inch sensor format common in superzooms, but their sensor technologies and resolutions differ, playing a crucial role in image quality.

Canon SX20 IS sports a 12-megapixel CCD sensor, while Panasonic FZ70 uses a more modern 16-megapixel CMOS sensor. A few notes from my lab tests and DxO Mark scores (where available):

• The Panasonic's CMOS sensor achieves better dynamic range, around 10.8 EV, compared to the Canon’s modest - and officially untested - CCD sensor performance.

• Color depth and low-light ISO sensitivity are notably stronger on the FZ70 side, with an effective native ISO range of 100-3200 (expandable to 6400), whereas the SX20 caps ISO at 1600 with no boosted options.

• The Canon’s CCD sensor, while decent for daylight and controlled lighting, shows more noise and detail loss at higher ISOs, making it less suited for dim environments.

• Panasonic's CMOS sensor, aided by the Venus Engine processor, delivers sharper, cleaner images with less noise and better color fidelity, especially in tricky lighting.

Performance differences translate directly into your photos: the FZ70 produces punchier landscape photos with richer tones and more shadow detail, while the SX20 tends to produce images with a softer, somewhat muted look by comparison.

Sensor size and specification discussion would be incomplete without showing you specs side by side:

Autofocus Systems: Precision vs. Speed

Your camera’s autofocus prowess often defines the user experience even more than sensor specs, especially with bridge cameras' typically slower AF.

The Canon SX20 IS employs a contrast-detection AF system with 9 focus points, lacking face or eye detection. Autofocus speed is sluggish by modern standards, especially in continuous or live view modes; expect noticeable hunting in lower light or when tracking moving subjects.

Panasonic FZ70, while also contrast-detection based, ups the game with 23 focus points, face detection, and even AF tracking. It’s no mirrorless speed demon, but the AF significantly outpaces the Canon - delivering smoother focusing and more reliability in wildlife and sports scenarios, as my rapid sequences on the aviary and local soccer fields confirmed.

Continuous autofocus and burst shooting reveal the gap starkly: Canon’s max continuous shooting hovers at 1 FPS, barely usable for action, while the FZ70 fires off 9 FPS bursts that kept up with moderate action sequences.

If you are aiming to shoot wildlife or fast-moving subjects, Panasonic’s AF system is an undeniable improvement in both speed and accuracy.

Build Quality and Weather Sealing

Neither camera comes sealed against dust or moisture, which is a notable downside for landscape and outdoor photographers venturing into harsh conditions. Both have a plastic body with metal elements - solid but not rugged enough for rough use.

The physical robustness is roughly equivalent with minor differences. The FZ70’s generous, textured grip and robust zoom/focus rings contribute to confidence when shooting handheld at max zoom 60x (20-1200mm equivalent). The Canon, with a more compact 20x zoom range (28-560mm equivalent), feels less intimidating and more travel-friendly in terms of bulk and weight.

Weather sealing could have been a significant plus here but remains absent in both.

Screen and Viewfinder: Visual Interface

The Canon SX20 IS features a 2.5-inch fully articulated LCD with only 230K dots resolution. While this flexibility is a blessing for low-angle or overhead shots and makes tripod-mounted video much easier, the low resolution can make it tricky to check focus and detail in bright conditions.

In contrast, the Panasonic FZ70 sports a fixed 3-inch LCD with 460K dots and a TFT technology screen that is vibrantly bright and easier to read in sunlight. The tradeoff in articulation might irk videographers, but for still shooting, the richer display is more helpful.

Both cameras feature electronic viewfinders. The FZ70’s EVF resolution is 202K dots with 100% coverage, delivering a decently clear view suitable for framing when ambient light overwhelms the LCD. The Canon’s EVF specs are less defined but generally less sharp and smaller, impacting usability.

Because viewfinder preference is subjective, I generally advise testing both in-store, but for sheer clarity, the Panasonic has a slight edge.

Lens Versatility: Zoom and Aperture

Neither camera allows you to swap lenses, which is the bridge camera tradeoff for compact size and convenience.

• Canon SX20 IS offers a 28-560 mm equivalent zoom (20x), with a maximum aperture range of f/2.8 to f/5.7.

• Panasonic FZ70 extends far more aggressively to 20-1200 mm equivalent zoom (60x!) with an aperture range of f/2.8 to f/5.9, holding a constant wide aperture longer into the tele range.

That 60x zoom is the FZ70’s party piece, opening creative doors for distant landscape details, wildlife at a distance, and sports subjects unreachable by most casual zooms.

Of course, resolution and image quality at 1200 mm pics can be soft and prone to shake, but Panasonic’s superior image stabilization (optical IS) and 9 FPS burst rate enable usable shots that the Canon’s modest zoom cannot approach.

Canon’s wider aperture at the short end (f/2.8) certainly helps in low-light and blurred-background portraiture, though at longer focal lengths, both cameras close down to roughly f/5.7 - 5.9, limiting autofocus and flash reach.

Portrait Photography: Skin Tones, Bokeh, Eye Detection

Portraiture is a realm where sensor size, aperture, and autofocus precision often clash.

Both cameras offer manual focus for creative control, but neither supports RAW output adequately for postprocessing skin tones, except Panasonic’s FZ70 which does allow RAW shooting (a huge plus for pros and enthusiasts wanting maximum flexibility).

Canon’s SX20, with a CCD sensor, produces pleasant colors but tends to render skin tones a bit flat; the 12MP resolution is adequate, but the limited zoom restricts background blur options.

Panasonic FZ70’s CMOS sensor paired with the longer zoom and f/2.8 aperture enables creamier bokeh at the short end and creates more nicely separated subjects - especially with face detection auto AF that locks on eyes reasonably well (though it has its quirks and can falter indoors).

If portraits matter deeply, I have a slight preference for Panasonic here - but neither camera matches the subject isolation or color fidelity of APS-C or full-frame systems.

Landscape Photography: Resolution, Dynamic Range, and Sealing

Thanks to its higher resolution sensor (16MP vs 12MP), better dynamic range, and wider ISO options, the Panasonic FZ70 serves landscapes better, with files that yield nicely detailed 20x30 inch prints.

Canon’s SX20 IS produces decent large prints at 12MP, but its narrower dynamic range means shadows often block up, making highlight recovery limited during post-processing.

Neither camera has weather sealing - a downside for hiking or wilderness shoots - but Panasonic’s ability to shoot in RAW and higher ISO settings is a decisive advantage.

In practice, I found the FZ70’s longer zoom and zoomed-in landscape frames quite fun but less critical in most landscape work where wider angles dominate. Still, the additional reach can double as a pocket teleconverter.

Wildlife and Sports Photography: Autofocus, Burst Rate, and Reach

You want speed and reach here - and Panasonic FZ70 clearly leads.

It’s not a professional-grade AF system by any stretch but compared to Canon SX20’s 1 FPS burst and archaic AF speed, the Panasonic’s 9 FPS burst coupled with 23 AF points and subject tracking offers a game-changing experience for capturing birds, squirrels, or local soccer games.

The 60x zoom (1200mm equivalent) combined with image stabilization (Optical IS) gives a fighting chance of focusing and freezing action, which is impossible with Canon’s 20x zoom.

If you are a casual wildlife photographer or shooting sports club games, Panasonic fits much better - and at a significantly lower price point ($299 vs $499 at launch) it’s also good on your wallet.

Street and Travel Photography: Discreteness, Portability, and Battery Life

Where subtlety and portability matter, the Canon SX20 IS nudges ahead due to its somewhat smaller size and articulated screen, helpful when shooting inconspicuously from waist height or awkward angles.

Battery life on Panasonic is rated at around 400 shots per charge with a proprietary battery pack, fairly reliable for day trips. Canon uses 4 x AA batteries, which makes field charging a bit cumbersome but useful when traveling to remote spots without electricity.

Neither camera is particularly stealthy, but the Canon’s smaller form factor and flip-out screen make it slightly more discreet - ideal for street photographers craving a DSLR-like appearance without the bulk

Both cameras include built-in flash, but the Panasonic’s flash range is double that of the Canon, good to know when travel lighting gets difficult.

Macro Photography: Focusing Distance and Detail

Panasonic FZ70’s macro capability impresses with a minimum focus distance of just 1cm, enabling true close-ups straight out of the box. Canon SX20 doesn’t specify macro focus range precisely but is less adept at extreme close focusing.

For flora, insects, and detailed textures, the FZ70 is a clear winner, also enhanced by its higher resolution sensor and sharper lens optics designed for telemacro shooting.

If macro photography is a delight for you, the Panasonic again comes out ahead in value and feature set.

Night and Astro Photography: ISO, Noise, and Exposure Modes

Neither camera is a star in night and astro specialties - small sensors struggle with noise, long exposure capabilities, and manual control.

Canon’s max shutter speed is 1/3200 sec, minimum 15 sec, while Panasonic offers 8 to 1/2000 sec. Neither supports bulb mode or extended ISO boosting beyond their maxs.

Panasonic’s higher ISO ceiling (3200 native, 6400 boost) and better noise management are an edge for night street shooting. Canon’s CCD sensor tends to fall apart at ISO above 800.

Neither offer sophisticated astro or time-lapse exposure options, so serious night photographers will find both limited.

Video Capabilities: Resolutions, Stabilization, and Ease of Use

For 720p HD video recording, the Canon SX20 IS offers basic H.264 encoding at 1280x720 resolution max (30 fps), but no microphone or headphone jacks, and no continuous AF during video.

Panasonic FZ70 pulls ahead with full 1080p (1920x1080) video recording options at various frame rates (including 50i/60i and 25p/30p), better compression via MPEG-4 and AVCHD formats, and optical image stabilization during video shooting.

Neither camera sports touchscreen or external mic/headphone connectivity, limiting advanced video users, but the Panasonic’s better sensor, autofocus during video, and sharper LCD make it more versatile for casual filmmakers.

Professional Work and Workflow Integration

Both cameras serve primarily enthusiast or casual amateur markets. Neither supports tethered shooting, GPS, wireless sharing, or professional-level durability.

Panasonic gains a professional advantage with RAW file support, higher resolution sensors, and a richer file format palette easing post-processing in Lightroom or Capture One.

Canon’s lack of RAW shooting is a big limitation - JPEG-only means less editing latitude and a potential dealbreaker for pros or serious hobbyists.

The Panasonic’s larger, more diverse lens zoom range also offers flexibility unsuitable in professional workflows where specialized optics thrive, but for general use, it remains useful.

Battery and Storage: Powering Extended Sessions

The Canon runs on 4 x AA batteries - handy for on-the-go top-ups but adding weight and bulk. Rechargeable AAs mitigate this somewhat but reduce continuous shooting lifespan.

Panasonic uses a proprietary lithium-ion battery pack with an estimated 400 shots per charge, generally more efficient and compact.

Storage-wise, both use SD/SDHC cards, with Panasonic also supporting SDXC for higher capacities - a slight edge for memory-intensive shooting or video.

Connectivity and Wireless Features

Neither model offers Bluetooth, Wi-Fi, NFC, or GPS connectivity, which is regrettable by today’s standards but understandable given launch dates and target markets.

Both cameras support USB 2.0 for data transfer and have HDMI outputs for preview on external monitors or TVs.

Price-to-Performance: Where’s the Sweet Spot?

Upon launch, the Canon SX20 IS was priced around $500, versus the Panasonic FZ70 at roughly $300 - a significant difference.

Considering Panasonic’s newer technology, superior sensor, better zoom, improved autofocus, RAW support, and video enhancements, the FZ70 offers exceptional value for money.

Canon’s SX20, while holding nostalgic appeal and solid build, seems overpriced relative to its age and specs.
