Panasonic GF5 vs Pentax H90: A Hands-On Comparison for Enthusiasts and Professionals

In forty years of shooting nearly every type of camera, I’ve come to appreciate how diverse photographic tools can powerfully influence the creative process. Today, I’m diving deep into two very different pieces of kit that nonetheless target casual to entry-level users: the Panasonic Lumix DMC-GF5 mirrorless camera and the Pentax Optio H90 compact. While they seem worlds apart, both camera systems offer distinct advantages and trade-offs worth dissecting for anyone seeking a capable everyday shooter.

I’ve spent considerable time in the field with each, putting their specs, builds, and imaging capabilities through my stringent tests - from portraits to landscapes, sports to macro, and beyond. Let me share my hands-on findings, technical insights, and practical recommendations drawn from thousands of frames and hours of experience.

First Impressions: Size, Weight, and Handling

One of the first things I notice when evaluating cameras is their physical presence and ergonomics. Compactness and comfort are paramount for travel, street, and event shooters who carry their gear all day. Here, the Panasonic GF5 adopts a classic rangefinder-style mirrorless form, whereas the Pentax H90 is an ultra-portable fixed-lens compact.

The GF5, measuring 108x67x37 mm and weighing roughly 267 grams, feels solid and well-balanced in hand, especially with Micro Four Thirds lenses attached. Its thoughtfully designed grip and textured surfaces encourage confident one-handed shooting even in brisk weather or dynamic situations.

In contrast, the Pentax H90 is smaller (101x65x28 mm) and lighter at 153 grams. It’s extremely pocket-friendly and unobtrusive. I found it ideal for casual shooting or as a backup camera when discretion and speed are priorities. However, its slim profile means fewer physical controls and less heft for stable framing - factors beginners often overlook.

The GF5's more substantial build and dedicated grip zone edge it as the better ergonomic choice for longer sessions or when precision is critical.

Control Layout and User Interface: How Intuitive Are They?

Anyone who’s spent hours fumbling dials knows that intuitive control placement is key to seizing fleeting moments. I conducted side-by-side usability tests under various lighting conditions.

The GF5 boasts a clean, tactile control scheme with dedicated mode dials, exposure compensation buttons, and a touch-enabled rear 3-inch LCD with 920k-dot resolution - all designed to put essential functions at your fingertips. The touchscreen interface adds a fluid layer of quick AF point selection and menu navigation, which I deeply appreciated when shooting on the move.

By contrast, the H90’s control scheme is decidedly minimalist, fitting for its compact class but limiting for those seeking granular exposure adjustments or creative modes. The 2.7-inch screen has a lower 230k-dot resolution - adequate for framing but less helpful for critical focus confirmation or image review.

In practice, the GF5’s better control ergonomics and responsive touchscreen make it easier to dial in settings quickly and confidently, especially under pressure.

Sensor Size Matters: Image Quality and Dynamic Range Explored

Nothing impacts image quality more than the sensor hardware. I ran comprehensive standardized ISO tests, dynamic range measurements, and color depth analysis to benchmark the two cameras.

The GF5 features a Four Thirds sized CMOS sensor (17.3x13 mm, approx. 225mm²) sporting 12 megapixels. This sizable sensor area offers a substantial advantage over the Pentax H90’s 1/2.3-inch CCD sensor - a tiny 6.17x4.55 mm chip about 28 mm² in sensor area.

In practical terms, the Panasonic captures cleaner images with greater detail retention, especially in challenging lighting or high-contrast scenes. Its DXO Mark scores of 50 overall, 20.5 color depth, and 10 stops of dynamic range translate into richer tonal gradations and superior shadow recovery.

The Pentax H90’s smaller sensor results in more noise at elevated ISOs and limited dynamic latitude. Its maximum ISO 6400, while useful on paper, introduces visible degradation after ISO 800-1600.

If image quality and flexibility post-capture are priorities - especially for landscapes or portraits requiring nuanced skin tone rendition - the GF5’s sensor technology decisively outperforms the H90.

Visual Experience: Exploring Displays and Interface Feedback

An excellent viewing experience builds confidence and reduces missed shots. I examined both cameras’ rear screen performance for visibility under diverse conditions.

The GF5’s 3-inch TFT touchscreen with wide viewing angle and 920k-dot resolution allows sharp, bright image composition and intuitive touch AF. Outdoors, its display remains readable under direct sunlight with minor adjustments.

The H90’s fixed 2.7-inch screen with only 230k dots falls short for detailed focusing or menu navigation. Its visibility under bright sunlight is compromised, making outdoor composition less precise.

In my workflow, the superior display of the GF5 provides critical confidence for manual focusing, precise exposure checks, and immediate composition adjustments on the fly.

Real-World Sample Images: Who Shines in Various Lighting?

The true test of any camera lies in output quality across a range of scenarios. I conducted extensive shooting sessions in natural and artificial lighting, capturing portraits, landscapes, and street scenes.

• Portraits: The GF5 renders skin tones with pleasing softness and accurate colors, aided by its 12MP sensor and advanced Venus Engine processor. Its 23-point contrast-detection AF, including face detection, helps nail sharp focus and beautiful background separation, despite not having in-body stabilization or an electronic viewfinder. The H90, while usable for casual portraits, suffers from noisier images and muted colors, with slower AF performance limiting efficacy on moving subjects.

• Landscapes: The GF5’s wider dynamic range and higher resolution afford more detailed landscapes with preserved highlight and shadow detail. The H90’s abbreviated dynamic range and modest pixel count translate to flatter, less vibrant results.

• Street Photography: The H90’s diminutive size makes it superb for candid shoots where discretion is valued. However, its slower startup time and locked aperture across zoom ranges can hamper image quality in variable lighting.

Ranking Camera Performance Across Photography Genres

To better picture relative strengths, I synthesized performance data across key photographic disciplines based on my practical testing.

The Panasonic GF5 unsurprisingly ranks higher overall, excelling in image quality, autofocus, and versatility. The Pentax H90 performs respectably in compact-friendly categories but trails in technical prowess and professional features.

Here’s how they stack up in detail:

• Portraits: GF5 wins confidently due to better AF eye/face detection and image quality.
• Landscape: GF5’s superior sensor and dynamic range are clear advantages.
• Wildlife: The GF5’s higher burst speed (4 fps) and faster AF outperform H90’s single fps.
• Sports: GF5 is marginally better for low-light and tracking.
• Street: H90’s small footprint aids discretion but lags in responsiveness.
• Macro: GF5’s interchangeable lenses edge out fixed lens macro capability.
• Night/Astro: GF5’s high ISO performance and exposure controls dominate.

Autofocus Systems: Speed, Accuracy, and Versatility

Both cameras adopt contrast-detection AF but differ markedly in implementation.

The Panasonic GF5 provides 23 AF points with face detection and continuous AF tracking, complemented by touch-to-focus capabilities. While lacking phase detection, its AF speed and reliability are solid for entry-level mirrorless.

The Pentax H90 uses a basic 9-point system without face detection or continuous AF, resulting in sluggish acquisition and occasional focus hunting in low contrast.

Hands-on, I found the GF5’s autofocus noticeably faster and more dependable, especially in dynamic environments like events or wildlife.

Lens Ecosystem and Image Stabilization: What’s Your Lens Journey?

An advantage of the GF5’s Micro Four Thirds mount is access to a wide lens ecosystem - over 100 lenses spanning fast primes, zooms, macros, and specialty optics. This flexibility makes it adaptable to many photographic fields.

The H90’s fixed 28-140mm equivalent lens with moderate aperture (f/3.5-5.9) limits creative choices. It does boast sensor-shift image stabilization, moderately effective at mitigating camera shake at longer focal lengths.

In contrast, the GF5 lacks in-body stabilization but benefits from optically stabilized lenses broadly available. For instance, Panasonic’s optical stabilizers paired with its contrast-detection AF allow sharper handheld shots than the H90 in many cases.

Battery Life and Storage: Staying Power on the Road

The GF5 offers approximately 360 shots per battery charge with a proprietary battery pack, which is reasonable for mirrorless but may require spares for extended outings.

The H90’s battery model (D-LI68) is compact, but official life expectancy data is minimal. It does support SD/SDHC media plus internal storage.

I noted the GF5’s USB 2.0 and HDMI ports enable tethered shooting and external monitor use, whereas the H90 lacks HDMI, limiting professional workflow integration.

Connectivity and Extra Features: Wireless, Video, and More

Connectivity is essential in the modern photographic workflow. The GF5 surprisingly lacks wireless options such as Wi-Fi or Bluetooth, relying on USB and HDMI connections only.

Conversely, the H90 includes an Eye-Fi card compatibility for wireless image transfer - unique among its class - but this is outdated by current standards.

For video, the GF5 records Full HD 1080p at 60 fps, supporting AVCHD and MPEG-4, offering flexibility and quality for casual videographers. The H90 maxes out at 720p 30fps with Motion JPEG format - better suited for basic home videos.

Durability: Can These Cameras Brave the Elements?

Neither camera offers environmental sealing, waterproofing, or shock resistance. Both are strictly indoor/dry weather companions unless you invest in additional protective gear.

The GF5’s rangefinder-style design and build quality inspire more confidence in daily use, but neither is built for harsh conditions.

My Testing Methodology: How I Arrived at These Conclusions

I’m committed to thorough testing protocols emphasizing controlled settings and real-world shooting. For this comparison:
