Panasonic LX100 II vs Pentax Optio H90: A Hands-On, In-Depth Compact Camera Comparison for Enthusiasts and Pros

When it comes to compact cameras, the spectrum is wide: from tiny pocket snappers to large sensor powerhouses that can double as capable travel companions or backup tools for professionals. Today, I put two such models head-to-head: the Panasonic Lumix DC-LX100 II (released in 2018) and the Pentax Optio H90 (launched way back in 2010). While both fall under the “compact” umbrella, they serve markedly different segments, with greatly varied feature sets and target users.

Having tested thousands of cameras over my 15+ years in photography - and wrestled with both budget cheapskates and premium gear - I’ll walk you through real-world performance, technical insights, and usability to help you decide which compact might suit your photography style, budget, and expectations best.

Let’s check out what sets these two apart and where one might best serve your portfolio or pocket.

Size, Ergonomics & Handling - How Do They Feel In Your Hands?

First impressions count, especially when it comes to ergonomics. You want a camera that fits comfortably during long shoots but doesn’t weigh you down on a hike or city walk.

• Panasonic LX100 II: A large sensor compact, it weighs 392g and measures 115 x 66 x 64 mm. It’s chunkier, with a classic rangefinder style and a solid grip molded for clubs of thumbs like mine. The control layout is considered and designed for photographers who want manual dials for aperture, shutter, and exposure compensation. The body feels professional yet portable.

• Pentax H90: A true small sensor compact, it only tips the scale at 153g and measures 101 x 65 x 28 mm. Much more pocketable, it’s slim and light, perfect for casual carry. But in terms of ergonomics, it’s a “minimalist” - no grip, tiny buttons, and generally less tactile feedback, which can frustrate in extended sessions.

In terms of top-side control design, the Panasonic clearly invites manual operation and experimentation, while the Pentax adopts a simple point-and-shoot philosophy.

If you want a camera you can tweak like a manual telescope, the LX100 II wins hands down. But if discreet, grab-and-go shooting is your thing, the H90 fits the bill without complaints.

Sensor and Image Quality - The Heart of the Matter

Time to talk about what truly separates these cameras: their sensors.

• Panasonic LX100 II packs a Four Thirds sensor measuring 17.3 x 13 mm (about 225 mm²) with a 17MP resolution. This sensor size is large for a compact camera, giving it a significant advantage in light gathering, dynamic range, and noise control. Coupled with the Venus Engine processor, it handles JPEG rendering and high ISO noise suppression well. It supports raw capture - a must-have for serious post-processing.

• Pentax H90 comes with a tiny 1/2.3” CCD sensor (6.17 x 4.55 mm, around 28 mm²) shooting 12MP images. While adequate for well-lit daylight shots, the small sensor limits image quality drastically - dynamic range is shallow, and noise creeps in rapidly as ISO climbs. Worse, there is no raw support, locking photographers into JPEGs that compress away detail and limit editing latitude.

In practice, the LX100 II delivers much cleaner images in low light, smoother skin tones in portraits, and noticeably richer detail in shadows and highlights. The Pentax struggles outside bright conditions, making it a poor choice for demanding applications.

Framing, Focus and Composing - The Viewfinder and Screen Battle

The experience of composing your shot is critical - especially for street shooters and landscape photographers.

• Panasonic LX100 II features a 3-inch, 1.24 million-dot touchscreen LCD along with a sharp electronic viewfinder (EVF) boasting 2.76 million dots, 100% coverage, and 0.7x magnification. This dual system means you can shoot comfortably in bright sunlight using the EVF, or compose creatively with touch focus and intuitive menus on the LCD. The fixed type screen means no variation angles, but the high resolution is a treat for reviewing focus.

• Pentax H90 offers a smaller 2.7-inch LCD with only 230k dots, no touchscreen and no viewfinder at all. Composing means relying solely on the LCD, and under bright conditions it can be difficult to assess focus and exposure. The lack of EVF limits effectiveness in strong sunlight or when working with low angles.

For photographers who like to “look through” the camera rather than at a screen, the LX100 II is far superior, adding accuracy and stability in fast-paced or bright environments.

Lens and Zoom: Focal Range and Aperture

While both cameras have fixed lenses - non-interchangeable - their specifications and optical quality vastly differ.

• Panasonic LX100 II sports a fast Leica DC Vario-Summilux 24-75 mm f/1.7-2.8 (equivalent focal length after 2.1x crop factor). This is versatile for portraits, walk-around, and even quick macros thanks to a close focusing distance of 3cm. The fast apertures help in low light and create beautiful creamy bokeh, especially pleasing for portrait shooters seeking subject isolation.

• Pentax H90 comes with a 28-140 mm f/3.5-5.9 zoom lens - broader reach but much slower lenses, limiting low light use and bokeh quality. Macro shots start at 10cm, a bit clumsier to get tight frame fills. This lens is fine for casual snapshots but won’t impress in more demanding creative situations.

If you want to push artistic boundaries or shoot in varied lighting, the LX100 II’s lens is a significant step up.

Autofocus: Speed, Accuracy, and AF System

Autofocus (AF) can make or break your moments, especially in wildlife, sports, or street photography.

• Panasonic LX100 II employs a contrast-detection AF with 49 focus points, including face detection and touch AF on the LCD. Continuous AF tracking is supported, and the camera is reasonably quick to lock focus in good light. While it cannot match today’s fastest phase-detection systems, it’s perfectly serviceable for portraits, travel, and even some wildlife if the light cooperates.

• Pentax H90 uses contrast-detection AF with only 9 AF points, lacking face detection or continuous AF modes. Burst shooting is non-existent (1 fps max), and AF speed is slow, making it ill-suited for action or fleeting subjects.

For fast-paced photography, the LX100 II offers reliable focus with greater flexibility; the H90’s AF system feels dated and limiting.

Burst Shooting and Buffer Capacity

• Panasonic LX100 II shoots up to 11 fps continuous burst - impressive for a compact - with raw buffer allowing a decent string of images for sports or wildlife sequences.

• Pentax H90 can only manage 1 fps, making action photography an exercise in frustration.

Video Capabilities

Video is now a staple in hybrid shooters’ requirements.

• Panasonic LX100 II supports 4K UHD 3840x2160 at 30p with 100 Mbps bit rate using MP4 (H.264) codec. It also has 4K Photo mode for extracting high-res stills from video frames, enhancing versatility. There’s built-in optical image stabilization to smooth handheld footage, although no external mic input limits audio quality control.

• Pentax H90 is stuck with 1280 x 720p HD at 30 or 15 fps in Motion JPEG - severely limiting quality, file size efficiency, and editing flexibility. No image stabilization or audio inputs.

For vloggers, content creators, or anyone serious about video, the LX100 II is leagues ahead.

Battery Life and Storage

• Panasonic LX100 II uses a DMW-BLE9 Lithium-ion battery rated at 340 shots per charge. Modest but sufficient for a day’s casual shooting. Uses SD / SDHC / SDXC cards with UHS-I speed support.

• Pentax H90 uses a D-LI68 battery but no official battery life figures given (older generation, likely inferior endurance). It accepts SD / SDHC cards plus internal storage.

For long trips or heavy shooters, packing spare LX100 II batteries is recommended. The Pentax’s unknown stamina and older battery tech are potential weak points.

Connectivity and Extra Features

• Panasonic LX100 II offers built-in Wi-Fi and Bluetooth for quick sharing and remote control via app. It supports focus stacking, bracketing, post focus, and timelapse recording - advanced features geared toward enthusiasts.

• Pentax H90 only connects via Eye-Fi card support (obsolete wireless SD card tech) and USB 2.0 port - hardly state of the art.

Build Quality and Weather Sealing

Neither camera has weather sealing or ruggedization. The Panasonic LX100 II’s metal body and premium feel suggest better durability compared to the lightweight plastic Pentax. If you need something tough for travel or outdoor adventures, neither is ideal but LX100 II is more reassuring in hand.

Real World Performance by Photography Genres

Let me now break down how these cameras stack up in various types of photography, reflecting on real shoots and lab tests.

Portraiture

• Panasonic LX100 II excels thanks to its large sensor, fast lens, good skin tone rendering, and eye detection AF. The creamy bokeh helps isolate subjects against backgrounds - a hallmark of quality portraits.
• Pentax H90 struggles with noisy images in dim light, slow AF delays, and flat JPEGs. The lens’ slow aperture limits background blur; portraits feel flat and unrefined.

Winner: Panasonic LX100 II without question.

Landscape

• LX100 II shows excellent dynamic range for shadows and highlights, especially shooting in raw. The 17MP resolution is enough for decent prints up to medium size, and the Leica lens is sharp and contrasty.
• The Pentax H90’s small sensor limits detail, and CCD sensors age poorly in highlight retention, resulting in washed out skies. Limited zoom and no lens options limit creative framing.

Verdict: LX100 II is the only serious landscape compact in this duel.

Wildlife & Sports

• LX100 II’s moderate continuous burst (11fps), AF tracking, and image stabilization enable some action shots but its limited telephoto reach (75mm equiv.) and lack of phase detection AF cap it for serious sports or wildlife.
• H90’s 1fps, slow AF (contrast-only), and lack of stabilization make fast action snaps frustrating, if not futile.

Suggested use: Neither replaces a DSLR or mirrorless system with longer lenses, but LX100 II is better backup.

Street Photography

• LX100 II’s compactish form, silent electronic shutter (max 1/16000s), and high ISO allow shooting discreetly under many conditions. The EVF aids composition, and zoom range covers wide to standard focal lengths.
• H90 is smaller and lighter but slower AF, no EVF, and limited zoom flexibility hamper responsiveness.

For street enthusiasts: Panasonic strikes a better balance of discretion and capability.

Macro Photography

• LX100 II can focus down to 3cm, enabling stimulating close-ups with sharpness and bokeh.
• H90’s 10cm minimum focus is less versatile for tight macro and lacks focus stacking options.

Result: LX100 II is far more competent and creative.

Night and Astro

• LX100 II’s larger sensor, higher ISO ceiling (up to 25600), and manual exposure modes lend it to night and astrophotography - although long exposures require tripod.
• H90’s 6400 max ISO and lack of raw mode limit low-light usability; noise and detail loss spoil subtle night shots.

Conclusion: LX100 II is fit for more demanding night work.

Video

• LX100 II’s crisp 4K recording and stabilization suit casual filmmaking, environmental videos, and vlogging.
• H90’s video is rudimentary, with low res and no mic input.

Travel and Everyday Use

• LX100 II offers versatility, good battery life, excellent image quality, and advanced connectivity.
• H90 is lightweight, simple, and budget-friendly but limited in features and image quality.

Professional Use and Workflow

• LX100 II supports DNG raw files and integrates well with modern software for editing.
• H90 offers JPEG only, restricting professional use.

Price and Value Analysis

Let’s get real: price can often be the tie-breaker. The Panasonic LX100 II typically retails around $1,000 - a solid investment for a high-end compact that can stand in for mirrorless in many scenarios.

The Pentax Optio H90’s street price hovers comfortably below $150, targeting casual users or those on tight budgets.

If you’re a serious hobbyist or professional looking for quality and flexibility, the Panasonic’s premium cost pays off many times over. For a second, basic snapshot camera, the Pentax is a bargain but comes with severe compromises.
