Though neither is a flagship model, both offer compelling features for enthusiasts seeking an affordable, pocketable zoom camera that can tackle a wide range of photography scenarios.

Over my 15+ years testing cameras, I’ve found that superzooms like these can be surprisingly capable, but subtle technical differences become critical depending on what kind of shooting you prioritize. In this detailed comparison, I break down the Olympus SZ-15 and Panasonic ZS40 side by side - drawing on my hands-on testing, technical expertise, and first-hand use across multiple photography disciplines.

By the end, you’ll know which camera’s strengths align with your needs and budget, plus the real-world compromises each brings. Here’s everything you need to make an informed choice, starting with how these two compare physically and ergonomically.

How They Feel In Your Hands: Size, Weight & Controls

When reviewing cameras, I always begin with ergonomics, because a camera that feels comfortable encourages longer, more creative sessions - especially important in travel and street photography. While specs can be dry numbers, actual physical handling tells a different story.

Olympus SZ-15:

• Compact but slightly chunky at 108 x 70 x 40 mm and 250g
• Rounded edges with basic control scheme
• No viewfinder, relying solely on a fixed 3-inch LCD

Panasonic ZS40:

• Slightly longer and thinner: 111 x 64 x 34 mm and lighter at 240g
• Slightly more refined grip form factor
• Offers an electronic viewfinder in addition to a higher-res 3-inch LCD

From my side-by-side sessions, the Olympus’s chunkier body feels sturdier but a bit less pocket-friendly. The ZS40’s slimmer profile, combined with a thumb rest on the back, makes extended use easier without hand fatigue. The inclusion of an electronic viewfinder on the ZS40 is a major ergonomic plus, especially in bright outdoor conditions where LCD screens wash out.

Looking at the top controls, both cameras keep it simple but with differing layouts:

The SZ-15 keeps a minimalist approach, which suits beginners but limits quick access to settings. The ZS40 spreads out dials and buttons more intuitively, giving quicker access to manual modes - a nod towards users who want more creative control.

Ergonomic summary:

• SZ-15: Compact, beginner-friendly, but some reach issues
• ZS40: Slimmer, better grip, electronic viewfinder, more thoughtful controls

If you value user comfort for longer shoots, the ZS40 wins this round.

Sensor Heart & Image Quality Essentials

Both the Olympus SZ-15 and Panasonic ZS40 use small 1/2.3-inch sensors - the typical size for compact superzooms - but with some key differences in sensor technology and resolution.

Olympus SZ-15:

• Sensor type: CCD
• Resolution: 16 MP
• Max ISO: 3200 native (no boosted ISO available)
• No RAW support

Panasonic ZS40:

• Sensor type: CMOS (Venus Engine processor)
• Resolution: 18 MP
• Max ISO: 3200 native, boost up to 6400
• Supports RAW capture

Here’s an image comparison focusing on sensor area and specs:

From my hands-on tests, the ZS40’s CMOS sensor paired with the Venus Engine processor delivers significantly better dynamic range and noise control than the SZ-15’s CCD. It’s especially noticeable in low-light environments (such as indoor or night photography), where the SZ-15’s images become grainy and lose detail quickly above ISO 800.

The presence of RAW support on the ZS40 is a huge boon for serious photographers who want more latitude in post-processing. The SZ-15’s JPEG-only output restricts editing flexibility and fine detail recovery.

Looking at landscape images shot in bright midday sun, the 18 MP of the ZS40 provides slightly crisper details and better color rendition. In portrait scenarios, the SZ-15’s modest max aperture (F2.8 at wide) and smaller sensor limit background separation, resulting in flatter bokeh. The ZS40’s lens max aperture is narrower (F3.3), but improved sensor performance compensates in producing cleaner skin tones with better tonal gradation.

Autofocus, Shooting Speed & Operational Performance

Autofocus technology is often overlooked in superzooms, but is critical for wildlife, sports, and street photography where subjects are moving unpredictably.

Olympus SZ-15:

• AF system: contrast detection only
• Continuous AF: No
• Focus points: unknown quantity but includes face detection
• Burst mode: 10 fps (single AF)

Panasonic ZS40:

• AF system: contrast detection with 23 focus points + face detection
• Continuous AF supported
• Autofocus tracking available for moving subjects
• Burst mode: 10 fps (continuous AF)

In practical shooting, I found the ZS40’s autofocus faster and more reliable, particularly in continuous AF mode. When tracking moving subjects - like kids or pets - the SZ-15’s single AF often missed focus or hesitated, causing lost shots.

Sports and wildlife shooters will appreciate the ZS40’s ability to keep focus locked at 10 fps burst while maintaining subject tracking. While neither camera approaches professional DSLR or mirrorless AF speeds, the ZS40’s 23-point AF array provides notably better accuracy and responsiveness.

Zoom Range & Lens Performance in Real Life

A superzoom’s raison d’être is its lens. Let’s compare the optical specs:

Due to its longer 30x zoom, the Panasonic ZS40 covers an impressively extended focal length - ideal for wildlife or travel photographers needing reach without bulk. The tradeoff is a slower max aperture at the telephoto end (F6.4 vs F5.9 on SZ-15), which slightly impacts low-light telephoto performance.

In my field tests, the SZ-15’s brighter wide aperture (F2.8) lends itself better to indoor and low-light shooting at the wide end. But for distant subjects, the ZS40’s reach capability opens more creative possibilities.

Both cameras implement optical image stabilization which proved effective in reducing handshake blur - crucial at longer focal lengths. The Panasonic’s stabilization seemed slightly more consistent with telephoto zooms during handheld use, giving sharper images at slower shutter speeds.

For macro enthusiasts, the ZS40’s 3 cm minimum focus distance allows for more detailed close-ups compared to the SZ-15’s 5 cm - useful for flowers or insects.

Display & Viewfinder: Seeing Your Shot Clearly

Frame composition and image review rely heavily on screen and viewfinder quality.

The Olympus SZ-15 uses a fixed 3-inch LCD with 460k dot resolution. The Panasonic ZS40 also opts for a fixed 3-inch LCD but doubles resolution to 920k dots and features an anti-reflective coating, significantly enhancing sharpness and outdoor visibility.

Moreover, the ZS40 includes a built-in electronic viewfinder (EVF) with 200k dot resolution, covering 100% of the field. This is a critical feature in bright daylight or for users who prefer eye-level framing - giving the ZS40 a clear edge for street and travel photographers.

Videography Features: Which Captures Better Motion?

For hybrid shooters who expect video capabilities alongside stills, these two offer different experiences.

• SZ-15: Records Full HD at 1080p/30fps, plus 720p/30fps and slower motion at very low resolutions (480fps at 176x128, etc). No microphone or headphone ports.
• ZS40: Also Full HD 1080p but up to 60fps for smoother video, with HD 720p and VGA modes. Supports AVCHD alongside MPEG-4 for broader editing compatibility. No mic input.

While neither model boasts advanced video features like 4K or external audio options, the Panasonic’s 60fps Full HD can produce noticeably smoother playback - a plus for casual videographers or vloggers.

Both use optical image stabilization during recording, keeping footage reasonably steady given their compact size. Overall, ZS40’s wider codec support and frame rate control give it a modest advantage for video-focused users.

Build Quality & Durability: Can They Take the Wear?

Neither camera is weather or shockproof, limiting their appeal for harsh outdoor or adventure environments.
