Olympus SZ-15 vs Panasonic ZS3: A Hands-On Comparison of Two Compact Superzooms

As someone who has rigorously tested hundreds of cameras, the choice between compact superzoom models is a familiar crossroad for enthusiastic photographers seeking versatility and portability in a small package. The Olympus SZ-15 and Panasonic Lumix DMC-ZS3 (also known as the Lumix TZ7) represent two generational approaches to this category. Both offer notable zoom ranges and convenience, yet differ markedly in autofocus sophistication, exposure controls, and real-world usability.

I’ve spent considerable time with each, examining their features and performance across varied shooting scenarios to bring you an authoritative, experience-driven comparison. Whether you’re into portraits, landscapes, wild adventures, or casual snapshots, this review will clarify which points matter most and help you decide which camera better fits your style and needs.

First Impressions: Size, Handling, and Build

When picking up these two compacts side-by-side, the size and grip noticeably influence handling, especially for enthusiasts who enjoy shooting handheld for longer stretches.

Olympus SZ-15 vs Panasonic ZS3 size comparison

The Olympus SZ-15 measures 108 x 70 x 40 mm and weighs 250 g, while the Panasonic ZS3 is marginally smaller and lighter at 103 x 60 x 33 mm and 229 g. These subtle differences make the ZS3 feel slightly more pocketable and discreet, but the SZ-15 boasts a more substantial grip. This added heft contributes to stability, a boon when shooting at extended telephoto focal lengths or in low-light situations without a tripod.

Both cameras are plastic-bodied with a modest build quality typical for their price range but neither offers weather sealing or robust environmental resistance. So, for anyone shooting outdoors frequently or in challenging conditions, external protection would be necessary.

Ergonomics-wise, neither camera surprises. The SZ-15 leans on a traditional button-and-dial layout, making access to common controls more straightforward - a feature made clearer when comparing the top plates:

The ZS3’s more minimalist control scheme means you often rely on menus, which slows operation down, especially in fast-paced situations such as wildlife or sports photography.

Sensor and Image Quality: The Heart of the Matter

Both cameras utilize 1/2.3" CCD sensors, a common choice in this category that balances cost and compactness. That said, the Olympus SZ-15 uses a 16-megapixel sensor, whereas the Panasonic ZS3 offers 10 megapixels. Their sensor areas are similar (around 28 mm²), so the numerical resolution difference directly impacts image detail and cropping flexibility.

In practice, the SZ-15’s higher resolution sensor produces crisper images with better fine detail rendition, especially noticeable when printing or cropping. That said, the higher pixel count comes with a minor trade-off: elevated noise levels beyond ISO 800, which is expected for small CCD sensors.

The ZS3 handles high ISO noise more conservatively, thanks partially to its lower resolution sensor and a maximum native ISO of 6400, compared to the SZ-15’s top native ISO 3200. However, the increased sensitivity comes at the cost of more aggressive noise reduction and less detail retention, visible in my side-by-side image gallery:

In daylight, both excel at typical superzoom output, producing vibrant, well-exposed photos with pleasing color rendition. The SZ-15 tends to pull slightly ahead with better contrast and dynamic range handling, especially in landscape shots where shadow and highlight preservation matter. Panasonic’s ZS3, on the other hand, benefits from less aggressive JPEG processing that keeps images looking natural but may feel slightly flatter.

Autofocus Performance: Speed, Accuracy, and Tracking

Autofocus is a critical factor when shooting fast-moving subjects or low-light conditions. Here, the cameras reveal contrasting designs rooted in their respective eras.

The Olympus SZ-15 employs contrast detection AF with face detection and continuous tracking, but no phase detection elements. Importantly, it allows manual focus - a feature I found invaluable for macro and precise portrait work. Its autofocus performance is reasonably quick in good light but slows markedly in dim conditions, a drawback I noticed during my indoor event testing.

The Panasonic ZS3 uses contrast detection AF with 11 focus points but lacks face or tracking detection capabilities and no manual focus option. I experienced more hunting under low light and struggled to obtain focus lock on off-center subjects. Its burst shooting rate of only about 2 frames per second limits its usability for action photography compared to the SZ-15’s 10 fps capability, which, while modest relative to DSLRs, is impressive for a compact.

For wildlife or sports enthusiasts, the SZ-15 offers a more reliable system to capture fleeting moments despite its limitations.

Exposure Controls and User Interface

The Olympus SZ-15 wins hands down when it comes to exposure flexibility. Full manual modes, aperture and shutter priority, exposure compensation, and custom white balance put significant creative power in your hands.

In contrast, the Panasonic ZS3 is geared more towards the casual shooter, lacking shutter or aperture priority and manual modes. Exposure compensation is nonexistent, and while it offers custom white balance, the absence of bracketing or advanced metering modes limits its usefulness in tricky lighting.

Both cameras feature a 3-inch fixed LCD display with comparable 460k-dot resolution:

Although neither has a touchscreen or articulating design, the screens provide decent brightness and color rendition. The lack of viewfinders on both models disrupts framing precision, especially in bright sunlight - a downside for outdoor photographers.

The SZ-15’s menu system is intuitive, with dedicated physical controls speeding adjustments, especially beneficial in rapidly changing scenarios. The ZS3’s more menu-reliant interface feels slower and less intuitive during on-the-go shooting.

Zoom Range and Lens Characteristics

Superzoom cameras live and die by their lens versatility. The Olympus SZ-15 impresses with a massive 21x zoom spanning from 23 to 483 mm equivalent, whereas the Panasonic ZS3 covers a more restrained 12x zoom from 25 to 300 mm.

This extended reach means serious telephoto potential with the SZ-15, ideal for capturing distant wildlife or sports. However, the SZ-15’s maximum aperture narrows from f/2.8 at wide angle to f/5.9 at telephoto, slightly dimmer than Panasonic's f/3.3-4.9 lens, which performs marginally better in low-light wide-angle scenes.

For macro lovers, the Panasonic ZS3’s closer focusing distance of 3 cm outperforms the SZ-15’s 5 cm, delivering greater magnification and detail, particularly useful for botanical or insect subjects.

Both have optical image stabilization - vital given their modest apertures and long zoom ranges - and perform admirably to reduce handshake, especially on telephoto shots handheld.

Video Features and Capabilities

If your creative pursuits include videos, the cameras differ significantly in recording specs.

The Olympus SZ-15 shoots full HD video at 1080p and 30 fps, using AVI MPEG4 or Motion JPEG formats. While video quality is satisfactory for casual use, it lacks microphone input or headphone output, restricting sound control. The camera does offer slow-motion capture modes at very low resolutions, though these are mostly gimmicks.

The Panasonic ZS3 records HD video at 720p and 30 fps in AVCHD Lite format. This codec optimizes storage without sacrificing too much quality, making the ZS3 preferable for longer video clips on memory cards. However, it does not offer 1080p recording, and audio control options are also limited.

Neither model supports advanced video features like 4K or in-body stabilization systems that would appeal to serious videographers.

Connectivity, Storage, and Power

Connectivity is basic but functional on both cameras. The Olympus SZ-15 provides built-in Wi-Fi and GPS - features surprisingly useful for travel photographers who want to geo-tag images and quickly share shots without a PC.

The Panasonic ZS3 lacks any wireless functionality, an understandable omission for a 2009 camera but a meaningful downside by 2013 standards.

Both share USB 2.0 ports and HDMI outputs for viewing on TVs. Storage-wise, the SZ-15 supports SD/SDHC/SDXC cards, while the ZS3 works with SD/SDHC and MMC cards plus has limited internal memory.

Battery life specs are not prominently advertised for either, but in my testing, the SZ-15’s SLB-10A lithium-ion battery comfortably lasted a day of mixed use. The ZS3’s battery performance is comparable, though slightly less impressive under continuous video recording.

Real-World Use Across Photography Disciplines

With specs and ergonomics clarified, how do these cameras perform in context? Let’s dig into the major photography genres.

Portrait Photography

The SZ-15’s face detection autofocus and manual focus options facilitate sharp portraits with pleasing skin tones and decent bokeh given the sensor and lens constraints. Its 16MP resolution enables cropping for framing refinement without glaring quality loss.

The ZS3’s lack of face detection and slower AF makes portrait shooting less precise and more labor-intensive. Lower resolution also sacrifices some detail that discerning portraitists might appreciate.

Landscape Photography

Both cameras struggle with dynamic range compared to modern sensors but the SZ-15 shows a marginal advantage due to better image processing, which helps retain details in shadows and highlights. The broader aspect ratio options (including 1:1) enable creative framing. Absence of weather sealing limits harsh outdoor use.

Wildlife and Sports

The SZ-15’s longer zoom, faster continuous shooting (10 fps), and tracking autofocus secure it as a better choice for wildlife and sports photography. The ZS3’s slower AF and 2 fps burst hinder capturing fast motion.

Street Photography

ZS3’s smaller size and weight lend it to street photography where portability and discretion matter. However, slow focusing and zoom can slow reaction time.

SZ-15’s bulkier feel may deter candid shooting out of hand, but superior AF speed makes it ultimately more reliable for decisive moments.

Macro Photography

Panasonic wins here with a closer focal minimum and less noise at higher ISO. The SZ-15’s manual focus can help but its minimum macro distance limits tight close-ups.

Night/Astro Photography

Both cameras’ CCD sensors produce significant noise at ISO above 800. Neither supports RAW or long exposures needed for astrophotography. The SZ-15’s ISO ceiling at 3200 and manual exposure modes offer marginally better control than Panasonic’s.

Video Use

SZ-15’s Full HD mode and better codec support suit handheld casual videography; ZS3’s AVCHD Lite codec is efficient but capped at 720p.

Neither is recommended for professional video work.

Travel Photography

Here, the Olympus SZ-15 nails versatility with Wi-Fi, GPS, longer zoom, and exposure flexibility – a reliable companion for comprehensive travel shooting albeit at some size cost.

The Panasonic ZS3’s lighter, smaller form and easy operation suit travel for casual snapshots with low maintenance.

Professional Workflow

Neither camera supports RAW capture, limiting professional post-processing control. File management and workflow integration are basic - expect straightforward JPEGs only.

Image Stabilization and Shutter Performance

Both cameras include optical image stabilization, crucial when shooting at long zooms or slower shutter speeds handheld. The SZ-15’s stabilization appears slightly more effective in my tests, particularly in telephoto range.

Shutter speed ranges are similar (SZ-15: 8 to 1/2000 sec; ZS3: 60 to 1/2000 sec), but only the SZ-15 offers true shutter priority and manual exposure modes - indispensable tools for creative shooting.

Price and Value Assessment

With both cameras priced around $200 in their markets (used or discount new), they target budget-conscious buyers seeking all-in-one convenience.

The Olympus SZ-15 edges ahead due to more modern features, better image quality, versatile exposure tools, and extended zoom range. The Panasonic ZS3, while somewhat dated, still delivers ease of use and compactness valuable for casual shooters.
