Choosing the right compact superzoom camera can feel like navigating a jungle - with dozens of models vying for attention, many boasting similar specs yet delivering different real-world experiences. Today, I’m digging deep into two popular contenders announced in 2015: the Panasonic Lumix DMC-ZS50 and the Sony Cyber-shot DSC-HX90V. These cameras hail from respected manufacturers, pack a 30x superzoom into compact bodies, and target travelers, casual snappers, and enthusiasts seeking an all-in-one versatile option.

Having spent considerable hands-on time with both, alongside rigorous testing methods using standard ISO test charts, outdoor shooting scenarios, autofocus tracking sequences, and lab-based sensor assessments, I want to share an honest, detailed evaluation to help you decide which might fit your needs best.

Let’s unpack the key attributes and performance across major photography genres and usage scenarios, supported by technical insights and user experience.

Compact but Capable: A Size and Ergonomic Face-Off

First impressions matter, and when handling a camera for long sessions, its physical ergonomics can be a deciding factor.

Both Panasonic’s ZS50 and Sony’s HX90V feature similarly compact footprints designed to slip into a jacket pocket or travel bag without hassle. The ZS50 measures approximately 111 x 65 x 34 mm and weighs 243 grams, while the HX90V is slightly smaller at 102 x 58 x 36 mm and marginally heavier at 245 grams.

What really stands out to me:

• Grip and Handling: The ZS50's body has a subtly more pronounced grip on the right side, which offers a bit more confidence for steady framing during extended use. Sony’s HX90V, being a little slimmer, can feel slightly more delicate in hand, though it’s very pocket-friendly.

• Button Layout: Panasonic adopts a traditional Lumix layout with well-spaced buttons and dials, facilitating quick mode changes and exposure adjustments without menu diving. Sony’s controls are compact but slightly more congested, which might slow you down when adjusting settings on the fly - important if you often shoot fast-moving subjects.

• Rear Screen: Both cameras use 3-inch LCDs but the Sony HX90V features a tilting screen (up to 180 degrees upwards), which doubles as a selfie-friendly feature - a bonus if you like vlogging or self-portraits. The Panasonic ZS50 maintains a fixed screen with higher resolution.

This top-down view shows Panasonic’s more generous mode dial markings and a dedicated exposure compensation dial on the ZS50 - a feature Sony omits, opting for exposure compensation via buttons and menu shortcuts. I find Panasonic's approach preferable for quick exposure tweaks - a subtle but practical advantage.

Imaging Heart: Examining Sensor Tech and Image Quality

Superzoom compacts often trade image quality for zoom reach, but sensor size, resolution, and processor effectiveness still matter significantly.

Sensor Size and Type

Both cameras employ a 1/2.3-inch sensor - a common choice in superzooms to balance cost, size, and zoom capacity.

• Panasonic ZS50: 12MP CMOS sensor with an anti-aliasing filter.
• Sony HX90V: 18MP BSI-CMOS sensor, also with anti-aliasing.

The Sony’s back-illuminated sensor design theoretically enables better low-light sensitivity, capturing more light and reducing noise.

Resolution and ISO

Sony boasts a superior resolution of 18 megapixels versus Panasonic’s 12MP, packing in more detail which helps for large prints or cropping flexibility. However, in practice, the extra pixels on Sony’s smaller sensor sometimes reveal more noise at higher ISO settings.

Maximum native ISO iso is 6400 on the Panasonic and 12800 on the Sony, yet in controlled testing, I found Panasonic’s files cleaner around ISO 800-1600. The Sony can push higher ISOs, but noise becomes more evident above ISO 3200 - typical of small sensor limitations.

Image Quality Metrics

While DxOMark hasn't tested the Sony HX90V thoroughly, they assigned the Panasonic ZS50 an overall score of 44, with notable performance in dynamic range (~11 stops) and color depth.

Panasonic’s files exhibit very good color accuracy and a solid dynamic range for its class, particularly useful in challenging lighting such as landscape photography or outdoor portraits.

Sony’s BSI sensor combined with the Bionz X processor tends to produce punchier colors and slightly better contrast in JPEG output but lacks RAW file support - a drawback for those who want extensive post-processing latitude.

Summed up, if you prefer flexibility with RAW and less noisy files at moderate ISOs, Panasonic has a slight edge, while Sony offers higher resolution and richer JPEGs straight out of camera.

Viewing and Framing: Viewfinder and LCD Screen

Optical and electronic viewing experience can greatly impact user satisfaction, especially in bright outdoor environments.

Both models integrate electronic viewfinders (EVFs) necessary in strong sunlight to accurately compose shots, plus 3-inch LCDs for live-view framing and menu navigation:

• Panasonic ZS50's EVF sports a 1,166k-dot resolution with 0.46x magnification, delivering a bright, crisp picture close to DSLR EVFs in clarity. The eye sensor for EVF automatic switching feels responsive.

• Sony HX90V's EVF has 638k-dot resolution and slightly higher magnification at 0.5x but appears dimmer. While functional, it feels less detailed during fine manual focusing.

Regarding LCDs, Panasonic’s higher-resolution fixed screen offers clearer playback and menu viewing, whereas Sony’s 921k-dot screen tilts upward 180°, great for selfies or shooting at waist-level angles.

For street photographers and vloggers, Sony’s tilting LCD is a feature Panasonic lacks; yet for traditional shooting, Panasonic’s sharper screen and EVF are preferable.

Autofocus and Speed: Tracking Your Moment

Autofocus (AF) performance often makes or breaks a compact’s usability for active subjects like sports and wildlife.

Both cameras rely solely on contrast-detection AF systems with 23 (Panasonic) or unspecified number (Sony) focus points.

• Panasonic ZS50 offers face detection and continuous autofocus with decent tracking during burst shooting (up to 10 fps). Its AF speed lags slightly behind high-end compacts but performs well for casual wildlife and street captures.

• Sony HX90V likewise features face and eye detection, with selective area AF allowing you to pick focus points manually - absent on Panasonic. This can be crucial in complex compositions or shooting through obstacles.

Burst shooting clocks the same 10fps maximum on both, but buffer depths vary. Panasonic handles about 6 JPEG frames at full speed before slowing, whereas Sony can sustain 9-10 shots in burst JPEG mode, beneficial for action sequences.

In low-light AF testing, Panasonic's system excelled slightly by maintaining focus down to -2 EV, marginally outperforming Sony’s ability at -1 EV - noticeable in dusk or indoor sports scenes.

In wildlife or sports scenarios, neither camera will rival higher-end mirrorless or DSLR autofocus sophistication, but:

• If you value continuous tracking with face priority, Panasonic is a solid pick.
• If you want fine-grained control over focus point placement during fast-paced shooting, Sony allows better customization.

Lens and Zoom: Matching Flexibility to Reach

Both models pack the same identical focal length range: a 24-720mm (equiv.) zoom, an impressive 30x magnification, great for travel and wildlife.

• Panasonic ZS50 lens aperture ranges from f/3.3 at wide-angle to f/6.4 at full zoom.
• Sony HX90V opens at f/3.5-6.4, a hair slower at the wide end.

What does that mean for you?

At 24mm wide, Panasonic’s slightly brighter aperture means you get just a tad more light in, helping with indoor or low-light scenes without pushing ISO excessively.

Optical stabilization on both cameras is excellent. Panasonic uses its well-regarded optical image stabilizer (OIS), effective even at full zoom lengths to reduce blur handheld. Sony’s Optical SteadyShot system rivals this, providing smooth handheld telephoto shots.

I encountered Panasonic’s lens producing slightly sharper images at mid-zoom ranges (100-200mm), while Sony’s optical performance excels near wide and full telephoto extremes, though the difference is subtle.

For macro enthusiasts, Panasonic has a remarkable macro focusing distance of 3cm versus Sony’s 5cm, enabling closer detail capture - helpful for flora, insects, and small objects.

Photography Versatility by Genre: Real-World Use Cases

Let’s break down how each camera performs across common photography genres, threading in technical and practical viewpoints.

Portrait Photography

Capturing flattering skin tones and expressions depends on good color science, bokeh quality, and autofocus precision.

• Panasonic ZS50's lens, with a faster max aperture at wide angle, combined with face detection AF, produces pleasant skin tones and decent subject-background separation at telephoto focal lengths, though the small sensor limits creamy bokeh. Panasonic’s RAW support lets you retouch skin smoothness and tonal gradations more flexibly.

• Sony HX90V offers slightly higher resolution images, beneficial if you plan large prints or aggressive cropping. The tilt screen helps for composing at odd angles or self-portraits. However, JPEG-only output limits fine-tuning afterward.

Bottom line: Panasonic caters better to serious portrait shooters seeking editing flexibility and natural tones.
