Wet vs. Wide: A Hands-On Comparison of the Canon PowerShot D30 and Panasonic Lumix DMC-SZ3

When narrowing down a compact camera purchase, two fascinating options from the mid-2010s come into focus: the rugged Canon PowerShot D30 and the sleek zoom-centric Panasonic Lumix DMC-SZ3. Though both emerged around the same era and inhabit the compact camera niche, they cater to very different needs. Having spent weeks extensively testing each in various environments, from a windswept beach to urban streets, I’m here to walk through how their differing design philosophies and feature sets translate to real-world photography - across portraits, landscapes, wildlife, and more. Let’s dive in.

Size, Build, and Handling - Where Durability Meets Portability

At first blush, size and ergonomics are where these two diverge most notably. The D30 is a chunkier, ruggedized beast designed to brave dust, water, minor shocks, and freezes. The SZ3, by contrast, leans into minimalism and portability.

The Canon D30 (109 x 68 x 28mm, 218g) trades compactness for durability, whereas the Panasonic SZ3 (95 x 56 x 22mm, 126g) goes light and slim.

The Canon D30's body is sealed to IPX8 standards, so it’s waterproof down to 25 meters - a feature that’s a photographer’s dream if you plan to shoot in harsh conditions or underwater. The SZ3 lacks any environmental sealing; it’s your typical pocket-friendly compact.

Ergonomically, the D30’s textured, rubberized grip means you won’t lose hold when your hands are wet or gloved. The Panasonic, thankfully, has a modest contour but can feel a bit slippery after prolonged use. Button layout is straightforward on both, but the D30 has buttons that are slightly larger and better spaced - ideal glove-wearers, take note.

Control-wise, the Canon’s top plate is simplified, focusing on ruggedness; the Panasonic’s design prioritizes compactness with fewer physical toggles.

In short, if you need absolute peace of mind taking your camera diving, snorkeling, or hiking in the rain, the D30 wins hands down. The SZ3 suits those who prefer a pocket camera for urban exploration or casual travel photography.

Sensor and Image Quality - BSI CMOS Meets CCD in the Small Sensor Arena

Both cameras use the ubiquitous 1/2.3" sensor size, but their sensor technologies differ significantly.

Despite identical sensor size, Canon’s D30 employs a 12MP BSI CMOS sensor, whereas Panasonic’s SZ3 uses a 16MP CCD sensor.

The Canon D30’s back-illuminated CMOS sensor is an evolutionary advantage, designed to capture more light and reduce noise, particularly beneficial for low-light and underwater shooting. The Panasonic SZ3’s CCD sensor, while higher in resolution at 16MP, is a classic design often associated with slightly less dynamic range and higher noise at elevated ISOs.

Testing in daylight, the SZ3 produces pleasantly sharp images with vibrant colors, attributable in part to its 10x zoom lens’s versatility and the CCD’s natural color rendition. However, zooming beyond 200mm equivalent reveals noticeable softness and chromatic aberration.

By contrast, the Canon’s BSI CMOS sensor retains better detail and cleaner shadows, especially in the tricky lighting conditions one might encounter outdoors or underwater. While the D30 maxes out at 12MP, this trade-off yields images that hold up better under moderate cropping and post-processing.

Dynamic range is a crucial factor for landscapes, and here the D30’s sensor again edges the SZ3. Shadows and highlights hold more detail, allowing more creative flexibility. The SZ3 tends towards slightly clipped highlights with its more limited dynamic range.

Screens and User Interface - Digesting Your Shots in the Field

Both models feature non-touch LCDs, a norm for their time and segment. Their screen characteristics influence usability in bright sun or rapid shooting scenarios.

The D30’s 3” PureColor II LCD with 461K dots feels brighter and more contrast-rich than the SZ3’s 2.7” TFT LCD at 230K dots.

The D30’s larger, higher resolution screen helps liven up image review and menu navigation. The Panasonic’s screen, while adequate, struggles a bit under direct sunlight, which could frustrate users trying to compose outdoors.

On the interface front, neither camera offers touchscreen input or advanced customization. Both rely on traditional button-driven menus and control dials, making quick adjustments possible but limited in scope. The D30's buttons, slightly larger and tactile, enhance confidence in wet or cold conditions.

Autofocus and Shooting Performance - Precision and Speed Tell Two Tales

Autofocus systems on these compacts share contrast-detection rather than phase-detection, which is expected given their class and vintage. Yet performance nuances do emerge with practice.

The D30 offers 9 focus points including face detection and center-weighted metering. It supports continuous autofocus and tracking, which proved useful in dynamic shooting, such as underwater swimming subjects or active children.

Panasonic’s SZ3 ups the number of AF points to 23, but lacks face detection. Interestingly, despite more AF points, I found its AF speed is marginally slower than the D30’s. This could be a consequence of the CCD sensor’s processing characteristics.

Continuous shooting speeds hover at 2fps for the D30 and 1fps for the SZ3. Not blazing fast, but competent enough for casual burst shooting - wildlife photographers aiming for fast action shots should look elsewhere.

Both cameras struggled in dim conditions, but the D30’s sensor and optical stabilization offered steadier focus acquisition and less blur. The SZ3 occasionally hunted noticeably under low light, partly due to slower lens aperture and sensor limitations.

Lens Reach and Versatility - Wide to Telephoto with Practical Limits

Here we see one of the most defining contrasts:

• Canon D30: 28-140mm equivalent (5x zoom), F3.9-4.8
• Panasonic SZ3: 25-250mm equivalent (10x zoom), F3.1-5.9

For outdoor enthusiasts needing solid zoom reach, the Panasonic’s 10x zoom is appealing: a 25mm ultra-wide to 250mm telephoto covers street to wildlife-ish distances. However, lens speed tapers off beyond 100mm, which can challenge image quality, especially in low light.

The Canon’s shorter, faster lens is balanced for general-purpose photography, and its macro focus range to 1cm beats the SZ3’s 5cm minimum. This makes the D30 surprisingly competent for casual macro shooting - think close-ups of wet pebbles, aquarium life, or raindrops on leaves.

Neither camera supports lens interchangeability, a reminder that these are point-and-shoots aimed at convenience.

Environmental Resistance and Durability - A Photographer’s Trust Factor

The Canon D30’s rugged design includes waterproof (up to 25m), dustproof, shockproof, and limited freezeproof claims. If you’re a diver, snorkeler, hiker, or prone to clumsy accidents, this ruggedness is a genuine lifesaver.

The Panasonic SZ3 offers no weather sealing. Its lightweight but delicate construction means you’ll want to baby it indoors or under mild weather at best.

Battery Life and Storage - Getting Shots Without the Pit Stops

Battery life is respectable on both, with the D30 rated for approximately 300 shots per charge - enough for a half-day adventure. The SZ3 clocks around 250 shots, slightly less, but still sufficient for casual outings.

Storage options are standard SD/SDHC/SDXC cards, with SZ3 adding internal memory, a minor plus for emergency file saving. The D30's battery model NB-6LH is easy to source, and overall I appreciated its reliable power delivery in colder conditions where battery efficiency can falter.

Video Capabilities - From Casual Vlogs to Travel Memories

Video remains firmly in amateur territory for both.

The Canon D30 shoots 1080p at 24fps using H.264 compression, a solid offering for its class, though with no microphone or headphone ports to tweak audio.

The Panasonic SZ3 maxes out at 720p 30fps in Motion JPEG format - less efficient and with larger file sizes. Video quality, unsurprisingly, is not a selling point here, but sufficient for casual captures.

Neither offers 4K or advanced stabilization beyond optical image stabilization for stills.

Photography Genre Performance - Park Walks to Portraits Under Pressure

Let’s break down where each camera excels (and where it falls short) across popular photographic styles.

Canon D30 generally edges out in action, landscape, and weather-resistant scenarios; Panasonic SZ3 shines with longer zoom reach.

Portraits

The D30’s face detection, coupled with a slightly wider aperture at the short end, supports decent skin tone rendering and bokeh smoothness. The SZ3 has no face detection but, with its longer zoom, can isolate subjects more easily from a distance, albeit with harsher background blur due to lens diffraction.

Landscapes

Dynamic range advantage and better weather sealing give the D30 the nod here. Its sensor handles the subtle gradients in sky and foliage better. The SZ3’s longer focal range can capture architectural details, but you’ll want a tripod due to image softness beyond 100mm equivalent.

Wildlife

The SZ3’s 10x zoom is tailor-made for casual wildlife hikes. But autofocus lag and slower continuous shooting slow action capture. The D30 has faster AF but limited zoom, restricting reach.

Sports

Neither camera is designed for sports. The D30’s faster AF and burst rate of 2fps are just passable but insufficient for fast action. The SZ3’s 1fps and slower AF limit its usability here.

Street

SZ3’s smaller size and weight aid concealment and ease of carrying. The D30 is bulkier and more conspicuous. However, the D30’s ruggedness makes it comfortable for unpredictable urban weather.

Macro

The holy surprise is the Canon D30’s 1cm macro focus range - uncommon among compacts, perfect for flora and objects. The SZ3’s 5cm minimum is less flexible.

Night and Astro

Bone noise reduction and dynamic range of the Canon’s CMOS sensor slightly help for night shots. Both cameras have long exposure options (up to 15 seconds D30, 60 seconds SZ3), but neither supports RAW files limiting post-processing rescue.

Video

D30’s full HD at 24fps is preferable for quality, though neither excels in video-centric features.

Travel

While the SZ3 is lightweight for travel, the D30’s waterproof and robust construction make it a trusty companion for adventurous trips.

Professional Use

Neither camera targets professional work. Both lack RAW support and advanced exposure modes.

Image Samples and Final Image Quality Verdict

In side-by-side shooting, I noticed the Canon D30 images presented less noise, marginally better color fidelity, and handled tough lighting with grace - reflections on water, underwater coral shots. The Panasonic SZ3’s higher resolution delivered more visible pixels but at the cost of noise and contrast. Images at full telephoto often blurred slightly under handholding.

Final Scores and Price-to-Performance Perspective

Both priced under $350 at launch (D30 about $329, SZ3 around $150), value depends on your priorities.

• The Canon D30 scores higher on durability, low light, and image quality.
• The Panasonic SZ3 scores on zoom range and everyday portability.
• Neither offers RAW files - a compromise for both advanced shooters and those wanting post-processing flexibility.
