Panasonic Lumix DMC-SZ3 vs Sony Cyber-shot DSC-HX350: A Hands-On Comparison for the Everyday Shooter

Selecting a compact camera today can feel a bit like wandering down a gadget aisle with a magnifying glass - how do you separate the genuinely useful from the merely pretty? Especially when models vary so widely in capability, size, and price. Today, I’m diving deep into two distinct entrants from Panasonic and Sony - the Panasonic Lumix DMC-SZ3 and the Sony Cyber-shot DSC-HX350 - both compact cameras but worlds apart when you peel back the specs.

Having personally handled thousands of cameras over 15 years, from full-frame beasts to wallet-friendly compacts, I’m here to give you a grounded, detailed rundown on what these cameras can deliver in your real-world photography adventures - and perhaps more importantly, where they might leave you wanting.

Let’s kick off with a good old look at their physical presence.

Size and Ergonomics: Pocketable or Prodigious?

Right off the bat, the Panasonic SZ3 leans heavily into lightweight portability. At just 126 grams and approximately palm-sized (95x56x22mm), it slips effortlessly into a coat pocket or small purse. It feels almost toy-like next to the robust Sony HX350, which tips the scales at 652 grams and dimensions closer to a small bridge camera (130x93x103mm). If minimalism and weight are decisive factors - especially for travel or everyday carry - the SZ3’s svelte build wins hands down.

Yet, size brings trade-offs. The SZ3’s compact design means a smaller grip and limited tactile controls - perfect for quick point-and-shoot snaps but not for those who savor manual tweaking or longer shoots where hand comfort matters. On the other hand, the HX350 offers a bulkier, SLR-like body with more pronounced grips and a substantial feel, lending confidence for longer sessions or outdoor shooting where stability counts.

Both cameras sport fixed zoom lenses, but their physical size differences also hint at their intended audiences: the SZ3 as an ultra-simple travel companion vs. the HX350 as a more ambitious superzoom tool.

For a clearer sense of their control layouts, the top view comparison can shine some light.

Control Layout and Top Design: Simple vs. Serious

Panasonic’s SZ3 sticks to the basics: few buttons, no dedicated dials, and a tiny shutter release. This camera is designed to be as fuss-free as possible, targeting users who want to compose and shoot with little else on their minds. There's no touchscreen, no electronic viewfinder, and adjusting settings means navigating menus through a 2.7-inch fixed TFT LCD with a modest 230k-dot resolution.

In contrast, Sony’s HX350 offers a more nuanced experience: a larger 3-inch tilting LCD (922k dots), an electronic viewfinder with 202k-dot resolution covering 100% frame coverage, and comprehensive manual controls including shutter and aperture priority modes. The HX350’s physical dials and buttons give photographers greater speed and precision in changing exposure settings - a welcome feature when you want to go beyond point-and-shoot.

Given my long-held belief that controls can make or break the shooting experience, I appreciate Sony’s approach here for more ambitious shooters, while Panasonic’s simplicity will please beginners not keen on fiddling.

Speaking of image quality, sensor specs are often the heartbeat of a camera’s potential.

Sensor Technology and Image Quality: CCD vs BSI-CMOS – Does Size Matter?

Both cameras sport a 1/2.3" sensor size - that’s small compared to APS-C or full-frame sensors - about 28mm² of light-collecting area, give or take, but the Sony HX350 edges slightly larger (6.17x4.55mm sensor dimensions) vs the Panasonic’s 6.08x4.56mm.

Where it really counts is technology inside: Panasonic uses an older CCD sensor, while Sony packs a more modern, backside-illuminated BSI-CMOS sensor. That difference matters because BSI-CMOS sensors typically deliver better noise performance in low light and higher dynamic range - both crucial for image quality.

In terms of resolution, Panasonic’s 16-megapixel sensor produces images at 4608x3456 pixels; Sony ups the ante with 20 megapixels (5184x3456). Yes, more pixels can mean finer detail, but in such small sensors, more pixels sometimes translate to more noise, especially at high ISO.

On ISO sensitivity, Panasonic’s native max ISO is 6400 (no expanded ISO), whereas Sony caps at 3200 natively but offers expanded ISO up to 12800 - a welcome feature for night and indoor shooting. That said, small sensors struggle beyond ISO 800–1600 generally, so manage your expectations.

In my hands-on tests outdoors and indoors, Sony’s images showed noticeably cleaner shadows and more retained highlight details, especially in challenging lighting. Panasonic’s CCD sensor produces a slightly warmer tone but shows increased graininess when ISO creeps higher.

Overall, the HX350 offers more versatility and image quality headroom, but neither camera competes with larger sensor alternatives in dynamic range or noise.

Screen and Viewfinder Usability: Composing Your Shot

The Panasonic SZ3’s fixed, small 2.7-inch TFT screen can feel cramped and dim, especially in bright sunlight. Coupled with the absence of any viewfinder, you’re reliant on framing via this basic LCD, which may frustrate precise composition or noisy crowds.

Conversely, the Sony HX350’s tilting 3-inch screen (you can angle it for high or low shots) with a crisp 922k-dot resolution brightens up composing. Added to that, Sony thoughtfully includes a built-in electronic viewfinder with 100% coverage. This finder is a game-changer when shooting bright landscapes or fast-moving subjects - you can frame with confidence and stability, reducing blur from shaky hands.

Furthermore, touch input is absent on both, so navigating menus requires physical buttons - nothing fancy, but Sony’s carefully laid out buttons fare better in responsiveness and accessibility.

Zoom and Lens Versatility: 10x vs 50x Reach – How Much is Too Much?

A standout difference here is zoom range. Panasonic’s SZ3 features a rather modest 25-250mm equivalent (10x) zoom with an aperture range of F3.1-5.9. This offers decent reach for everyday snapshots, portraits at the longer end, and some casual wildlife or telephoto needs, but lacks the punch for distant subjects.

Sony’s HX350 flexes its muscles with a jaw-dropping 24-1200mm equivalent (50x) superzoom lens, starting wide at F2.8 and narrowing to F6.3 at full zoom. This zoom range is astonishing for a compact and grants you the ability to capture sweeping landscapes, distant wildlife, and everything in between.

Having tested the HX350’s long reach up close, one must confess: yes, it does invite camera shake and dependency on a steady hand or monopod to keep shots sharp at full zoom, but the built-in optical image stabilization helps immensely. The Panasonic’s own optical stabilization assists with general blur reduction but can’t compensate for the loss of reach.

For macro enthusiasts, the Sony’s 1cm minimum focus distance outperforms the Panasonic’s 5cm, enabling more detailed close-ups of flowers and insects.

Autofocus and Shooting Speed: Capturing the Decisive Moment

Autofocus matters hugely if you’re photographing fast-moving action or candid street scenes. The SZ3 relies on contrast-detection autofocus with 23 focus points but lacks face or eye detection. It can focus slowly, especially in dimmer conditions, and only offers a sluggish continuous shooting rate of 1 fps. That means if you miss the moment, well… you mostly just miss it.

The HX350 improves with both contrast-detection autofocus and Sony’s typically reliable face detection. However, it notably lacks eye-tracking autofocus. Despite this, the HX350 shoots up to 10 fps in continuous mode - quite respectable for its class - making it better suited for wildlife or sports snapshots where burst shooting can catch that winning frame.

I found Sony’s AF noticeably quicker and more reliable in varying light, while Panasonic often hunts for focus in shadowy or low-contrast scenes.

Video Capabilities: From Casual Clips to Storytelling

If video is on your radar, here’s the lowdown. Panasonic SZ3 records HD video at 1280x720p at 30 fps using the dated Motion JPEG format - files that can be large and lacking in compression sophistication. No microphone input or advanced video options exist, and the image stabilization helps a bit but cannot replace a gimbal.

Sony’s HX350 steps up with full HD 1080p video at 60i or 60p depending on format (MPEG-4 and AVCHD). It supports HDMI output for external monitors and delivers steadier videos thanks to optical stabilization. While there’s no microphone jack, the overall video quality feels more professional and flexible.

Neither camera supports 4K video or modern codecs, so pro videographers might want to look elsewhere, but for casual to intermediate video use, Sony holds the advantage.

Battery Life and Storage: Shooting for Your Next Adventure

Battery capacity is a subtle yet vital aspect for travel and event photographers. Panasonic claims around 250 shots per battery charge, standard for entry-level compacts but restrictive for day-long outings. Sony edges slightly ahead with about 300 shots, alongside the benefit of a larger body that houses bigger batteries absorbing heavy usage better.

Both cameras accept SDXC cards, but the HX350 also supports Memory Stick Pro Duo - a nod to Sony’s proprietary ecosystem. For typical users, SD cards suffice, but it’s worth noting for cross-device compatibility.

Build Quality and Durability: Can They Take the Heat?

Neither model boasts environmental sealing, waterproofing, nor shockproof certifications. The Panasonic SZ3’s lightweight plastic body feels modest but decent for its price bracket, while the Sony HX350’s build quality earns higher marks with robust plastic and a grip that suggests it can tolerate a bit more wear and tear.

If you’re a professional photographer or travel enthusiast demanding rugged reliability, neither really holds up compared to weather-sealed DSLRs or mirrorless bodies, but for casual users, they’ll survive normal handling.

Real-World Photography Performance: Genre Breakdown

How do these cameras handle across common genres? Here’s my breakdown:

Portrait Photography

Panasonic’s limited aperture range (F3.1-5.9) and lack of face or eye detection make nailing skin tones and sharp eyes tricky, especially indoors. Bokeh is modest due to small sensor and lens limits.

Sony’s wider aperture at the wide end and face-detection autofocus assist portrait shots, though shallow depth of field remains elusive with small sensors.

Landscape Photography

Dynamic range on both is limited by sensor size, but Sony’s BSI-CMOS sensor and higher resolution offer better detail retention in highlights and shadows. The HX350’s vast zoom lets you capture expansive vistas or distant peaks with clarity, while Panasonic’s shorter zoom clips some compositional possibilities.

Wildlife Photography

Sony’s 50x zoom, faster continuous shooting, and quicker autofocus shine here. Panasonic struggles to focus quickly or track subjects, with only a 1 fps burst.

Sports Photography

Again, Sony’s 10 fps burst rate and solid AF make it a better candid sports shooter, although neither is truly optimized for professional fast-action shooting, where an APS-C or full-frame mirrorless would excel.

Street Photography

Panasonic’s small size beats Sony’s bulk for stealth and mobility, but lens reach and low-light capabilities falter. Sony’s face detection helps lock onto subjects, but the camera’s weight might deter discrete shooting.

Macro Photography

Sony’s 1cm minimum focus beats Panasonic’s 5cm, letting you get closer to tiny subjects with more detail.

Night / Astro Photography

Small sensors on both limit their usefulness for astrophotography. Sony’s higher ISO range offers some advantage, but long exposures and noise management are constrained.

Video

Sony’s Full HD video with better stabilization and format support is a clear winner.

Travel Photography

If ultra-light travel is key, Panasonic fits the bill. If versatility and range matter more, Sony wins despite size and weight penalties.

Professional Work

Neither camera serves well as a professional primary body - no RAW support on either, limited manual controls on Panasonic, and modest connectivity.
