Olympus VR-320 vs Panasonic Lumix ZS100: The Definitive Hands-On Comparison for Every Photographer’s Needs

Having tested thousands of cameras over the last 15 years, I love a good crossroads like the one these two compact superzoom cameras present. On the surface, the Olympus VR-320 and Panasonic Lumix ZS100 seem worlds apart - one an affordable “grab and go” point-and-shoot from 2011, the other a sophisticated large-sensor compact introduced in 2016. But how do they really compare when placed side-by-side in real-world use across portrait, landscape, wildlife, and more?

I spent extensive time shooting with both, putting their sensors, ergonomics, autofocus, zooms, and video through rigorous professional tests. My goal here is not to simply regurgitate specs, but to distill deep experience into clear, actionable guidance. Whether you're a casual enthusiast on a budget or a hybrid photo/video pro looking for a versatile travel companion, this comparison aims to help you find the right fit for your creative workflow.

Size, Handling, and Design: First Impressions Matter

The moment I picked up both cameras, their physicality told a story about their intended users and shooting styles.

The diminutive Olympus VR-320 (101x58x29 mm, 158g) is an ultra-compact, pocketable superzoom marvel of portability. Its slim depth and lightweight body make it a no-fuss option for casual strolls and family events where you want excellent reach without carrying bulky gear.

Contrast that with the Panasonic ZS100 (111x65x44 mm, 312g) - noticeably larger, denser, and more robust. It sits solidly in the hand, delivering a squeeze of confidence typical of more serious compacts. The extra heft isn’t just heft for heft’s sake - it houses a bigger sensor and a more advanced lens assembly, which I consistently appreciated when crafting images with more depth and precision.

The top view layout further highlights their divergent philosophies.

The ZS100 boasts dedicated dials, a mode knob, and customizable function buttons - ideal for photographers craving direct access to exposure settings on the fly. The Olympus skips manual controls entirely: it’s all about point-and-shoot simplicity, with a pared-down button array.

If you prioritize tactile control, the ZS100’s design aligns better with your needs. But if lightweight convenience and pocketability headline your wish list, Olympus earns points for discretion and ease.

Sensor Size and Image Quality: The Heart of the Matter

Here’s where the gulf between these two cameras widens significantly:

The Olympus VR-320 utilizes a tiny 1/2.3-inch CCD sensor (6.17x4.55 mm), standard for compact superzooms of its era. With 14 effective megapixels, it can produce decent 4:3 aspect ratio images at 4288x3216 resolution. However, the sensor's limited physical dimension inherently restricts dynamic range and ISO performance. CCD technology also tends to lag behind modern CMOS/MOS iterations in readout speed and noise control.

By contrast, the Panasonic ZS100 packs a large 1-inch MOS sensor (13.2x8.8 mm) delivering 20 megapixels. This is a quantum leap in sensor area to about 116.16 square mm - more than four times the surface area of the VR-320’s sensor. The result? Sharper images, excellent low-light capability, richer color depth (22.8 bits vs. untested but presumably lower for Olympus) and dramatically improved dynamic range (12.5 EV vs untested but limited on the VR-320).

In practical terms, I found ZS100 images maintained crisp detail from shadows through midtones to highlights, with noticeably less noise at ISO 800 and above - even pushing to 12800. The VR-320, expectedly, fared well at base ISO 80 to 160 but struggled beyond ISO 400, showing grain and smudged detail.

This disparity especially mattered for landscape and night shooting, where sensor performance defines the final image’s tonal richness and texture.

Display and Viewfinder: Composing Your Shot

Neither camera offers an optical viewfinder, but only one provides an electronic alternative:

The VR-320 relies on a basic 3-inch fixed TFT LCD with 230k-dot resolution - a modest screen that feels outdated by modern standards. In bright outdoor environments, it’s challenging to see details clearly. The lack of touchscreen also limits quick menu navigation.

The ZS100’s 3-inch fixed touchscreen delivers a crisp 1040k-dot resolution, a revelation for composing and reviewing shots with accuracy. Touch-enabled AF and menu selections brought efficiency to busy street photography sessions where time constraints ruled.

The ZS100 also incorporates a brilliant built-in 1166k-dot electronic viewfinder with full 100% coverage and good magnification (0.46x). Using this EVF was a game-changer for bright conditions and low-light shooting alike. Meanwhile, the lack of any viewfinder on the Olympus meant relying exclusively on the screen, limiting compositional control in challenging lighting.

Autofocus and Shooting Speed: Catching the Decisive Moment

AF speed and accuracy define how well a camera locks on fast-moving subjects and tracks complex scenes.

The VR-320 deploys a contrast-detection-only system with face detection but lacks continuous AF and manual focus options. This means autofocus hunts noticeably under low light or tricky scenes, and there's no way to "lock" focus on a moving target other than single AF mode. Burst shooting isn’t supported, so capturing fast action sequences is tough.

The ZS100 leverages 49 AF points with contrast-detection and on-sensor phase-detection (hybrid AF), plus touch AF and AF tracking modes. In practice, it nailed focus rapidly - even in low light or backlit conditions. Continuous AF and tracking made wildlife, sports, and street photography far more enjoyable, and its 10 fps burst helped capture fleeting moments consistently.

This autofocus prowess represents a huge upgrade in versatility and reliability for serious shooters, setting the Panasonic well apart from the entry-level Olympus.

Lens Performance and Zoom Versatility: How Far and How Sharp?

Both cameras feature fixed zoom lenses, but their optical reach and quality vary.

The VR-320 offers a 24-300 mm equivalent zoom, a hefty 12.5x magnification, with an aperture range of f/3.0-5.9. This impressive reach impressed me for basic wildlife snapshots or detail-rich cityscapes on a shoestring - but image sharpness declines at the telephoto end, and chromatic aberration is noticeable at wider apertures.

The Panasonic ZS100 sports a 25-250 mm equivalent lens (10x zoom), with a faster f/2.8 max aperture at wide-angle, narrowing to f/5.9 telephoto. The brighter f/2.8 aperture allows more light in, crucial for low-light or shallow depth-of-field shots, especially in portraits and street contexts.

Optical performance on the Panasonic lens was exceptional, outperforming the Olympus in corner sharpness and minimizing distortion. Its smaller zoom range is a worthwhile trade-off for image clarity and faster glass, especially when combined with the larger sensor.

Battery Life and Storage: Staying Powered and Ready

The VR-320 uses the Olympus LI-42B battery - a compact energy pack typical for point-and-shoots. While I couldn't find official CIPA numbers, real-world use indicates roughly 200-250 shots per charge before recharge is mandatory, making it suboptimal for long shoots without spares.

Panasonic’s ZS100, with a dedicated rechargeable battery pack (DMW-BLG10), impresses with a rated 300 shots per charge. Realistically, I averaged 270-300 shots with heavy EVF and wifi usage active, more than enough for a full day's shooting in the field.

Both cameras use SD/SDHC cards, but only the ZS100 supports SDXC for large capacity cards - an important consideration for extended 4K video sessions or high-res continuous shooting.

Video Recording Capabilities: Summer Holidays to Pro Vlogs

If video matters, this is where the two cameras dramatically diverge.

The VR-320 caps out at 720p HD (1280x720) at 30 fps using Motion JPEG - a now-legacy codec producing large files with modest compression. Its lack of microphone input and basic stabilization render it a simple option suited for casual clips rather than polished productions.

By contrast, the ZS100 shines in video department, offering full 4K UHD recording at 30p/24p, alongside 1080p at 60p. Video files use efficient MPEG-4 and AVCHD codecs with better compression and quality control.

While it lacks microphone and headphone jacks for professional audio, the ZS100’s in-body optical image stabilization and post-focus capabilities significantly enhance handheld and creative shooting.

This makes the Panasonic an excellent choice for hybrid shooters requiring high-quality video alongside stills.
