Panasonic Lumix ZS45 vs Pentax Optio W80: A Compact Camera Face-Off from Two Eras

Compact cameras have long balanced portability with functionality, catering to enthusiasts seeking simplicity without compromising versatility. Today, we'll place the 2015 Panasonic Lumix ZS45 side-by-side with the older 2009 Pentax Optio W80 - two small sensor compacts with distinct design philosophies and features reflective of their era. What can we glean about camera evolution, and which model suits specific photography needs? Having handled both extensively over varied lighting conditions and shooting scenarios, I’ll walk you through a deep dive covering ergonomics, imaging, autofocus, video, and more.

Let’s buckle up and examine these contenders through an expert’s eye.

Sizing Up the Contenders: Ergonomics and Handling

At first glance, these two compact cameras cater to the same crowded category: pocketable compacts, but their physical presence and handling cues differ substantially.

The Panasonic ZS45 measures 108x60x32 mm and weighs in at 249 grams with battery and card - a neat rectangle with pronounced grip contours. Its modest heft imparts a reassuring steadiness when shooting, especially with its 20x zoom lens extending far forward.

The Pentax W80 is smaller and lighter - 100x56x25 mm at 156 grams. Its shape is curvier, designed more for ease of slip-in pockets, but with less pronounced ergonomics. The reduction in physical volume is welcome for travel photographers wanting minimal load, though the tradeoff is decreased in-hand stability.

While the ZS45’s build feels more robust and modern (plastic but well finished), the W80’s compactness suggests ruggedness is sacrificed, despite its modest environmental sealing (something rare to find on a compact). The Pentax’s seals protect against splashes - great for outdoor shooting - but it’s noticeably thinner and lighter.

If you prize confident grip and camera stability, Panasonic nudges ahead here. But if minimal footprint and beach-proof snaps are your jam, the Pentax makes a compelling case.

Interface and Control: A Tale of Two Layouts

Exploring control schemes, the ZS45 and W80 reflect procedural shifts in camera design between 2009 and 2015.

On the Panasonic ZS45, dedicated buttons for exposure compensation, a mode dial, and a zoom rocker reside comfortably under the right hand. The shutter release has a satisfying travel, and the tilting 3” LCD screen allows for flexible framing. Though no touchscreen, the layout is logical and quick to operate once familiar.

The Pentax W80 pares down controls significantly - a simple layout with a modest mode dial, reduced buttons, and a fixed 2.5” screen with much lower resolution (230k dots, compared to 1040k on Panasonic). The shutter button travel is shallower, befitting its compactness but offering less tactile feedback.

Neither camera offers an electronic viewfinder, which may influence framing preferences, but both feature live view on LCDs. Panasonic’s 3” higher-res screen makes reviewing details easier, while Pentax’s smaller screen limits this slightly.

Overall, the Panasonic fosters faster access to manual and semi-manual controls (exposure compensation, aperture priority), a boon for enthusiasts who want direct control. The Pentax orients more to point-and-shoot simplicity, consistent with its 2009 design philosophy.

Sensor and Image Quality: More Than Just Megapixels

Both cameras pack a 1/2.3-inch sensor, a format common in compact cameras that prioritizes affordability and zoom range over ultimate image quality.

Looking closer at sensor tech:

• Panasonic ZS45: 16MP CMOS sensor with anti-alias filter, ISO 100-6400 native. The CMOS tech gives it an edge in noise handling and readout speed.

• Pentax W80: 12MP CCD sensor, ISO 64-6400 native. CCD sensors produce rich colors but tend to have slower readout and more noise at high ISO.

In real-world shooting, the Panasonic’s CMOS sensor delivers cleaner images in low light and better dynamic range. I saw more retained highlight details in challenging landscape scenes, likely due to improved sensor design combined with updated image processing.

The Pentax W80, while producing pleasing colors at base ISO, suffers noticeable noise at ISO 400 and above. Contrast falls off sooner, and landscape shots taken in shadows or indoors show more grain and softer details.

In bright daylight, both cameras manage fine prints with solid sharpness, but Panasonic’s higher resolution and noise performance make it the stronger performer overall.

Autofocus Performance and Shooting Speed

Autofocus (AF) speed and accuracy can make or break your images, especially when capturing motion or fleeting moments. How do these two stack up?

The Panasonic ZS45 employs a contrast-detection AF system with 21 focus points and face detection, including continuous AF tracking that smoothly adjusts focus during video or burst shooting. Its AF locks quickly - often under half a second in decent light - and maintains tracking well with moving subjects during continuous shooting at 10 fps, a rarity at this price.

The Pentax W80, being older and simpler, has a contrast AF with 9 focus points but lacks face or subject detection. Focus acquisition is noticeably slower, about a second in ideal light, making quick shots more challenging. No continuous AF means focus is locked with each shutter press only, and burst shooting is limited to 1 fps, limiting utility for action or wildlife shots.

I tested both on wildlife subjects - busy squirrels and darting birds. Panasonic excelled with quick response and tracking; Pentax delivered usable results but required more patience and predictive focusing.

For photographers needing speed and reliable AF in varied situations, ZS45 is the clear winner. Pentax W80 best suits relaxed shooting where speed is less critical.

Zoom Lenses: Reach and Capability Compared

Lens focal length ranges and aperture are fundamental to versatility in compact cameras.

• Panasonic ZS45: 24-480mm equivalent (20x zoom) with aperture f/3.3-6.4

• Pentax W80: 28-140mm equivalent (5x zoom) with aperture f/3.5-5.5

Panasonic’s 20x zoom vastly outclasses the Pentax in reach, offering extraordinary framing flexibility - useful when traveling or shooting distant wildlife. Though its telephoto aperture narrows to f/6.4 at max zoom, which challenges low-light handholding, image stabilization helps mitigate shake.

The Pentax’s 5x zoom is shorter but brighter at maximum aperture (f/5.5 tele), pairing nicely with its smaller sensor for daylight shooting. It begins macro focusing at just 1cm, enabling impressive close-ups.

Neither camera supports lens changes - fixed zooms limit system expandability, but the optics here suit their respective purposes.

If superzoom reach is a priority, Panasonic wins hands down. For everyday snapshots with some macro flair, the Pentax lens offers a fine compromise.

Macro and Close-up Capabilities

Close focusing distance and focusing precision matter for macro enthusiasts or those wanting detailed still life shots.

The Pentax W80’s macro mode shines at an ultra-close 1cm minimum focusing distance, letting you frame tiny subjects like flowers or insects with eye-popping detail relative to sensor size. Its lens sharpness in macro is decent, though limited by sensor resolution and noise.

The Panasonic ZS45’s closest macro focus is 3cm, respectable but less intimate than the W80. However, its higher sensor resolution somewhat compensates, allowing more crop potential in post-processing.

Neither camera offers focus stacking or advanced focus bracketing features - no surprise given their category and era.

For hobbyists intrigued by macro, the Pentax provides slightly more satisfying in-camera close-ups. The Panasonic’s strength lies elsewhere, though its image quality at macro distances is still solid.

Low Light and Noise: Managing the Shadows

Compact cameras never excel spectacularly at high ISO, given physical sensor limitations. Still, practical low light usability varies.

Testing both in dim indoor ambient lighting, Panasonic’s CMOS sensor produces more usable images at ISO 800 and manageable noise at ISO 1600. Noise reduction processing is effective but does slightly soften fine details.

Pentax images become visibly noisy by ISO 400, with chroma noise and loss of color fidelity increasing sharply above that.

Neither camera features in-body stabilization apart from Panasonic’s optical image stabilization (OIS), which aids handheld shots in lower light. The Pentax lacks stabilization entirely, demanding faster shutter speeds or tripod use.

In night scenes or astro-photography attempts, the ZS45’s maximum shutter speed of 1/2000s combined with longer exposures and OIS offer more versatility compared to the W80’s 1/1500s max shutter speed without stabilization.

If you plan to shoot beyond bright conditions regularly, the Panasonic’s noise control and stabilization stand out as key advantages.

Video: Evolving from Motion JPEG to Full HD

Video functionality underscores generational leaps between these cameras.

The Panasonic ZS45 captures Full HD 1920x1080 at 30p with MPEG-4 compression. Videos are smooth with decent color reproduction. Optical image stabilization is a boon, steadily handling handheld zoom shots. Unfortunately, indoor microphone quality is typical compact fare, and there’s no microphone input for improved audio.

Pentax W80 maxes out at 1280x720 HD video in Motion JPEG format, with 30p and 15p frame rates. File sizes are large; compression is outdated by today’s standards. Video footage is softer and less smooth, with no image stabilization or audio input.

Neither camera supports 4K or advanced video modes like slow motion or flat profiles.

For casual shooters wanting basic HD clips, Panasonic’s video quality and stabilization provide a more satisfying experience, while Pentax video suits occasional use only.

Battery Life and Storage: Practical Considerations

Battery endurance and storage options influence traveling photographers and frequent shooters.

The Panasonic ZS45 uses a proprietary rechargeable battery rated for approximately 350 shots. Real-world use shows about 250-300 photos with moderate LCD use and occasional flash - enough for a day of casual shooting.

The Pentax W80 runs on the D-LI78 battery, offering unspecified official capacity but my experience suggests slightly fewer shots per charge compared to Panasonic, compounded by less efficient older power management.

Both cameras rely on a single SD/SDHC/SDXC card slot. The ZS45 supports faster storage standards, contributing to smoother continuous shooting and video recording.

If long shooting sessions with minimal recharge are needed, Panasonic’s battery and faster data handling are safer bets.

Connectivity and Extras: Wireless, GPS, and Interface

Modern cameras increasingly afford wireless image sharing; here, there is a clear divide:

• Panasonic ZS45 includes built-in Wi-Fi, enabling quick image transfers to smartphones or tablets via Panasonic’s proprietary app. The USB 2.0 and mini-HDMI ports allow tethered control and viewing.

• Pentax W80 lacks wireless capabilities and HDMI out. USB 2.0 is available.

GPS is absent from both cameras.

Useful features such as auto bracketing and manual exposure modes are present only on the Panasonic - enhancing creative control.

Tilting LCD on the ZS45 aids compositional flexibility; the Pentax’s fixed lower-res screen feels more limiting.

Durability and Weather Resistance

While compact cameras rarely go deep into weatherproofing, the Pentax W80 offers some environmental sealing - a splash-proof shell protecting against humidity and rain. This is unusual for a cheap compact and a strong selling point for adventurous users.

The Panasonic ZS45 has no weather sealing, making it more vulnerable to moisture but otherwise solid in build quality.

If you shoot near water or in unpredictable outdoor conditions, the W80 provides modest peace of mind. For dry use or urban photography, the Panasonic well exceeds in other areas.

Image Samples Across Varied Conditions
