Panasonic GX850 vs Sony A350: A Detailed Comparison for Today’s Photographer

Choosing between the Panasonic Lumix DMC-GX850 mirrorless camera and the Sony Alpha DSLR-A350 might seem unusual at first glance. Released nearly a decade apart and reflecting two distinct camera system philosophies, these entry-level models target different types of users - yet each holds enduring appeal for photographers mindful of budget, size, or vintage value. Having put both cameras through extensive hands-on testing - covering everything from sensor performance to autofocus behavior - I’m here to offer you an authoritative guide that goes beyond mere specs.

Let’s embark on a journey that explores how these two cameras stand up in real-world photography across genres, technical performance, and usability. By the end, you’ll understand which is best suited for your style, workflow, and creative ambitions.

A Tale of Two Systems: Size, Handling & Design

Before diving into pixels and processor power, the physicality of a camera often sets the emotional tone for how it feels to shoot with.

Panasonic GX850 is a compact, rangefinder-style mirrorless body designed for discretion and portability. Weighing just 269 grams with dimensions of 107 x 65 x 33 mm, it slips comfortably into a jacket pocket - essentially a camera for travelers or street shooters who prize low profile. Its minimalist style can mislead you into thinking it’s a simple point-and-shoot, but it houses versatile controls and a tilting touchscreen that modern users appreciate.

Conversely, the Sony A350 is a mid-size DSLR weighing 674 grams and measuring 131 x 99 x 75 mm. It reflects the classic, more substantial grip associated with DSLRs, designed to feel balanced especially when paired with heavier lenses. The larger form factor supports traditional optical pentamirror viewfinder usage that some photographers prefer for its direct optical feedback, especially outdoors. That bulk also implies less stealth but greater physical reassurance when in hand.

Looking at the top control layouts, Panasonic opts for streamlined dials with touchscreen overlays, leaning on simplicity and touchscreen convenience but sacrificing numerous external buttons. Sony’s A350, on the other hand, boasts dedicated dials for shutter speed and ISO, an external exposure compensation dial, and a more conventional shutter release feel. This analog approach suits those who prefer physical feedback and instant manual access without menus.

Assessment: If you seek a lightweight, pocketable system with a modern interface, Panasonic GX850 excels. For photographers who require a firm grip, tactile controls, and the optical viewfinder experience, Sony A350 remains a solid choice.

Under the Hood: Sensor Size, Resolution and Image Quality

Sensor technology fundamentally shapes image quality - dynamic range, noise control, and color fidelity chief among them.

The Panasonic GX850 employs a 16-megapixel Four Thirds CMOS sensor sized 17.3 x 13.0 mm, notable for its lack of anti-aliasing filter (AA filter), which means crisper detail at the expense of some moiré risk. Panasonic’s Venus Engine processor enhances noise reduction and color reproduction, delivering a DxOMark overall score of 73, with impressive color depth (23.2 bits) and a wide dynamic range of 13.3 EV. Its native ISO range runs from 200 to 25600, and though it starts at a moderate base ISO, its high ISO capabilities - particularly in JPEG output - remain decent for a sensor this size.

The Sony A350 features a 14.2-megapixel APS-C CCD sensor measuring 23.6 x 15.8 mm, considerably larger in surface area than the GX850’s sensor, which typically translates to superior signal-to-noise ratio and greater light-gathering potential. However, CCD sensors are generally more power-hungry and lagged behind CMOS counterparts of its era in dynamic range and video capability. The A350’s DxOMark rating is lower overall, at 65, with color depth at 22.6 bits and dynamic range at 11.5 EV. ISO tops out at 3200 natively, meaning it’s less useful in very low-light scenarios.

Our extensive shootouts in landscape and portrait conditions reveal the GX850 producing slightly cleaner high ISO images with better detail preservation, while the Sony’s APS-C sensor shines in mid- to low-ISO ranges with a more three-dimensional color rendering - particularly noticeable with Sony’s older CCD color science.

In practice: Landscape and portrait photographers demanding richer tonal gradations and vibrant, nuanced colors might favor Sony’s sensor up to ISO 800. Meanwhile, those needing more ISO headroom and edge-to-edge sharpness opt for Panasonic’s modern CMOS.

Viewing, Composing and Interface Experience

For composition and review, the GX850’s reliance on an LCD is critical, while Sony’s DSLR feels traditional with its optical viewfinder.

Panasonic integrates a bright 3.0-inch tilting touchscreen with a 1040k-dot resolution - one of the finest for the price point when released. This screen offers excellent daylight visibility and the convenience of touch-to-focus, touch-shutter, and intuitive menu navigation - all advantages for quick, on-the-go shooting. The absence of an electronic viewfinder can be a downside for some, especially when shooting under bright sun or requiring precise manual focusing.

Conversely, Sony’s A350 includes a modest 2.7-inch tilting LCD with only 230k-dot resolution, lacking touchscreen functionality. Instead, it sports an optical pentamirror viewfinder with approximately 95% coverage and 0.49x magnification. This optical viewfinder helps in tracking moving subjects and composing in bright conditions without strain but offers no exposure simulation or live digital data overlays.

My take: The GX850’s touchscreen makes it more accessible for beginners and mirrorless fans, boosting creativity with intuitive controls. The A350’s classic DSLR interface will appeal to users rooted in traditional SLR habits who rely on an optical finder and dedicated buttons.

Autofocus Systems: Speed, Accuracy and Tracking Performance

Autofocus is one area where mirrorless cameras have made leaps forward since DSLRs of Sony’s era.

The Panasonic GX850 features a 49-point contrast-detection autofocus system with advanced face detection and continuous AF tracking. It supports focus bracketing, focus stacking, and even post-focus shooting modes that aid macro and precision-focused photographers - a boon for creative experimentation.

Sony’s A350 sports a 9-point phase-detection AF system and offers continuous AF for stills, but notably lacks contrast-detection or live autofocus in live view mode. It does not provide face detection or animal eye autofocus, features fundamental to modern cameras.

In real-world testing, the GX850’s autofocus felt quicker, more accurate in continuous tracking, and more effective in low light. Face detection was reliable for portraits and casual photography, while the Sony needed more manual focus intervention and struggled with moving subjects.

Burst rates further illustrate performance disparity: Panasonic shoots up to 10 fps in continuous mode, compared to Sony’s slower 3 fps.

Summing up: Sports, wildlife, and event photographers will find the GX850’s autofocus significantly more effective and versatile. The Sony A350 is adequate for static subjects and deliberate shooting styles but falls behind in speed-critical scenarios.

Lens Selection and System Ecosystem

Lens availability and adaptability are paramount for growing a camera’s usability across genres.

The Panasonic GX850 uses the Micro Four Thirds (MFT) mount, supported by two industry giants - Panasonic and Olympus - and a broad selection of third-party lenses. With over 100 native MFT lenses ranging from ultra-wide to telephoto primes and zooms, plus versatile macro options, the system is both mature and accessible. The 2.0x crop factor makes telephoto reach more affordable and compact.

Sony’s A350 uses the Sony/Minolta Alpha mount, offering access to the long-standing Alpha lens lineup and many legacy Minolta lenses. However, the availability of lenses is less extensive compared to MFT, and with Sony’s shift towards the newer E-mount mirrorless system, A-mount lenses are becoming increasingly niche. Still, for an APS-C DSLR, the 1.5x crop factor balances field of view and lens size well.

Both systems support manual focus extensively, but Panasonic’s focus bracketing and post-focus features present a modern edge.

My recommendation: As a user who values lens flexibility and future system growth, I advise leaning toward the Panasonic MFT ecosystem unless you already own Sony A-mount lenses or prefer larger APS-C glass.

Build, Weather Sealing, and Durability

Neither camera touts weather sealing, moisture resistance, or rugged protection, reflecting their entry-level status.

The Panasonic GX850’s plastic and metal construction feels solid though light, and while it lacks environmental sealing, it’s fit for casual travel and street use. The compactness reduces the potential to snag or hit hard surfaces.

Sony’s A350, designed more robustly, weighs significantly more, with a sturdier DSLR shell and deeper grip. Despite this, no formal weather sealing is provided either.

For photographers working in challenging environments - dusty hikes or unpredictable weather - the best practice remains protective cases and rain covers for both models.

Battery Life and Storage Flexibility

Battery endurance reflects different sensor and system efficiencies.

The Panasonic GX850 achieves approximately 210 shots per charge according to CIPA standards - a modest figure for mirrorless cameras, impacted by its power-hungry screen usage and in-body electronics. It uses Micro SD/SDHC/SDXC cards for storage, which are readily available and cost-effective.

Sony A350’s official battery life isn’t explicitly documented but is widely known to be strong for a DSLR with its optical viewfinder and CCD sensor. Estimated capacity lies around 500 shots per charge, making it friendlier for extended sessions. Storage uses compact flash memory and Memory Stick Duo formats - somewhat dated and costlier, but with respectable capacity.

Practical insight: If battery longevity is a priority (e.g., travel or fieldwork), Sony supports longer unplugged shooting. Meanwhile, Panasonic’s recharging capabilities and USB powering options offer their own convenience.

Video Capabilities: Mirrorless Advantage

Here is a clear domain where the Panasonic GX850 leads distinctly.

It offers 4K UHD video recording at 30p and 24p, with 4K photo modes, slow-motion Full HD recording, and modern H.264 compression in MP4 container. Features like electronic stabilization, timelapse recording, and accurate autofocus tracking during video unlock creative versatility.

Sony A350 offers no video recording at all, making it unsuitable for multimedia creators or vloggers who want integrated capture.

For still photographers planning occasional video and hybrid content, the GX850 provides an excellent introduction to 4K video and modern codecs, all within an unassuming package.
