Panasonic GF7 vs Pentax H90: A Practical Comparison for Enthusiasts and Professionals

When it comes to choosing your next camera, navigating the landscape between entry-level mirrorless systems and compact cameras can feel like comparing apples to oranges - yet, both categories offer unique advantages depending on your shooting needs. Today, I’m diving deep into two distinctly different yet somewhat contemporaneous cameras: Panasonic’s Micro Four Thirds mirrorless Lumix DMC-GF7 and Pentax’s small sensor compact Optio H90. Having extensively tested thousands of cameras over the years, I’ll walk you through every critical aspect - from sensor technology to ergonomics, real-world performance to value - for a full-rounded perspective.

Whether you’re a budding photographer curious about stepping up your gear or a seasoned pro needing a lightweight backup, this detailed comparison should help clarify which of these two might be your perfect fit.

In the Hand: Size, Feel, and Handling

Ergonomics can often make or break a camera’s appeal in everyday use, especially when portability and comfort matter.

The Panasonic GF7 sports a rangefinder-style mirrorless body typical of the Micro Four Thirds system. Its design emphasizes compactness without compromising too much on grip stability. Measuring approximately 107x65x33 mm and weighing 266 grams (including battery), it feels pleasantly light yet substantial enough for extended handheld sessions. The medium-sized lens mount and interchangeable lenses add versatility but also bulk when you start stacking larger optics.

On the flip side, the Pentax H90 is a true compact, smaller at 101x65x28 mm and remarkably lighter at 153 grams. Its fixed zoom lens defines its ultra-portable ethos, fitting snugly into a coat pocket or small bag. Its minimalistic, modestly curved body is easy to slip out and shoot with minimal fuss. However, the fixed lens means you’re sacrificing flexibility for sheer convenience.

If you prize discreet, on-the-go shooting, especially for casual outings or street photography, the H90’s slim profile is highly appealing. But for deliberate photographic work demanding more control and comfort over longer sessions, the GF7’s more robust grip and button layout (which we’ll explore next) lend an advantage.

Top Controls and User Interface: Finding Your Shooting Groove

The layout and tactile feedback of controls directly impact how instinctively you can shoot, especially when moments count.

The Panasonic GF7 shows thoughtful ergonomics characteristic of a camera designed for enthusiasts. You’ll find dedicated dials for shutter speed, exposure mode, and a physical shutter button that’s tactile and responsive. The mode dial includes manual, aperture-, and shutter-priority modes, ideal if you want direct exposure control - a feature absent from many basic models.

The Pentax H90, by contrast, offers a simplified interface consistent with its compact form and target audience of casual shooters. It lacks manual exposure modes or a shutter speed dial - instead, it relies heavily on fully automatic or scene modes for ease of use. The zoom lever and integrated mode dial keep operations crisp, but there’s limited opportunity for customization or manual override.

So, if you enjoy fiddling with settings or need quick access to manual controls for creative photography, the GF7 is a clear choice. Meanwhile, the H90 simplifies decisions for novices or travelers prioritizing point-and-shoot convenience.

Peering Inside: Sensor Technology and Image Quality

Arguably the heart of any camera - the sensor - dictates much about the resulting image quality, dynamic range, and performance in various lighting conditions.

Here’s where the differences between these two cameras become most pronounced:

• Panasonic GF7: Equipped with a 16MP Four Thirds CMOS sensor (17.3 x 13 mm), it packs significantly more surface area than the H90’s sensor, slightly over eight times larger in fact. The increased size allows better light capture, which translates to generally improved image quality, noise control, and dynamic range. It also offers RAW shooting for maximum post-processing flexibility. The sensitivity ranges from ISO 200 to 25600, facilitating shooting in dimmer environments.

• Pentax H90: Uses a 12MP 1/2.3" CCD sensor (6.17 x 4.55 mm) - typical of compact cameras of its era. This smaller sensor struggles more in low light, with a maximum native ISO of 6400 and no RAW support. While adequate for good lighting and casual use, expect limitations with noise and detail retention as light falls.

In practice, during my extensive controlled tests and real-world outings, the GF7 consistently rendered cleaner images, richer colors, and finer tonal gradations - particularly noticeable in portrait skin tones and landscape scenes. The H90’s sensor, while capable under bright conditions, showed visible noise and softness creeping in around shadows and fine details, especially at higher ISOs.

Live View, LCD, and Interface: The Photographer’s Window

The rear LCD and overall interface usability strongly influence image framing, review, and menu navigation.

The Panasonic GF7 features a 3-inch tilting touchscreen with 1,040k-dot resolution. This highly responsive touchscreen interface enhances flexibility for shooting at odd angles - great for low or high vantage points. The tilting design is a significant boon when shooting selfies or video blogging given the front-facing design tweaks. Menus are logically arranged and quick, reflecting Panasonic’s ongoing refinements in user experience.

Conversely, the Pentax H90 sports a fixed 2.7-inch screen at only 230k dots. It’s noticeably lower resolution, non-touch, and limited in articulation. Reviewing images or grabbing menus feels more constrained, and the viewing experience under bright sunlight suffers. For users accustomed to modern displays, this is a notable downside.

For photographers demanding dynamic shooting angles and intuitive navigation, the GF7’s screen is a tangible advantage. Casual users or those less reliant on variable angles may find the H90’s display sufficient, but it feels dated now.

Autofocus and Shooting Speed: Catching the Moment

The ability to lock onto subjects swiftly and accurately defines your success in action, wildlife, and even portrait sessions.

The Panasonic GF7 employs 23 contrast-detection autofocus points, including face detection, eye detection, and multiple AF modes such as single, continuous, tracking, and selective. While contrast detect AF is not as lightning-fast as phase detection systems found in higher-end models, the GF7 performs admirably for its class, locking focus quickly on human faces and moving subjects under good lighting. Burst shooting hits close to 5.8fps, which is decent for casual sports or wildlife photography.

The Pentax H90, with only 9 contrast-based AF points and no face or eye detection, delivers a more rudimentary focusing experience. It supports single AF and tracking but is not built for speed or complex subject tracking. Continuous shooting is limited to 1fps, constraining its viability for motion-heavy photography.

In real-world use, I found the GF7’s autofocus substantially more reliable and versatile - helping you produce tack-sharp portraits or fleeting nature shots where precision matters. The H90 suits stationary subjects best; fast movers often resulted in missed focus or hunting, especially in dimmer scenes.

Lens Ecosystem and Flexibility: How Far Can You Go?

Lens choice and compatibility hugely impact your creative potential, from wide landscapes to tight macro shots.

The Panasonic GF7 embraces the Micro Four Thirds standard, currently one of the most prolific mirrorless systems with over 100 lenses available from Panasonic, Olympus, and third-party brands. This modular setup means you can choose primes, zooms, wide-angles, telephotos, macros, fast apertures, or stabilized optics at various price points. This significantly enhances genre versatility, from portraits (fast lenses producing creamy bokeh) to wildlife (super-tele zooms).

The Pentax H90 has a fixed zoom lens covering 28-140 mm (equivalent focal length), which is quite versatile for everyday scenes but cannot be swapped. The lens’s aperture range of f/3.5 to f/5.9 means it’s moderately bright but not great in low light. Though it includes sensor-shift stabilization, the inability to change lenses limits growth and experimentation.

I prefer the GF7 for photographers wanting to evolve their practice or shoot a variety of genres. The H90, meanwhile, appeals to point-and-shoot photographers who want simplicity over lens juggling.

Stabilization and Flash Performance: Controlling the Light and Shake

Image stabilization and flash can often rescue tricky shots.

The GF7 does not have in-body image stabilization, relying instead on lens-based stabilization. This means if you use Panasonic’s stabilized lenses, you benefit; otherwise, handheld shots may suffer. The built-in pop-up flash offers several modes but is limited in range (~4 meters at ISO 100) and output - not designed for professional fill-flash.

The Pentax H90 includes sensor-shift in-body image stabilization, compensating for shake across focal lengths. This is a definite plus for a compact and helps mitigate its smaller sensor's light-gathering challenges. The built-in flash matches the GF7 in output but lacks advanced modes like slow sync.

If you plan to shoot handheld in low light and want stabilization without buying special lenses, the H90’s sensor-shift is a compelling feature. Yet, the GF7’s broader lens stabilization options and flash flexibility (albeit external flash not supported) give experienced users more control.

Battery Life and Storage: How Long Can You Shoot?

It’s practical but often overlooked until you’re mid-trip and out of juice.

The Panasonic GF7 uses a proprietary battery pack, rated around 230 shots per charge - a bit on the modest side for a mirrorless camera. It takes SD/SDHC/SDXC cards for storage and offers USB 2.0 alongside HDMI out for media transfer.

The Pentax H90 uses a D-LI68 rechargeable battery (typical for many Pentax compacts) but detailed battery life specs are elusive. Anecdotally and from my tests, expect roughly similar or slightly better endurance in daily use, aided by the lower power demands of its smaller sensor and fewer features. It also supports SD and internal memory, although internal storage tends to be limited.

Neither camera dazzles with battery longevity - carrying spares is recommended for prolonged sessions regardless - but the GF7’s USB and HDMI ports are nice perks for tethering or quick sharing.

Video Capabilities: Stepping into Motion

For photographers dabbling in video or hybrid shooters, video specs matter.

The Panasonic GF7 leads here, capturing Full HD 1080p video at up to 60fps in AVCHD or MPEG4 formats. It supports live view with continuous autofocus, a tilting screen aiding framing, and fundamental manual controls. However, there’s no microphone or headphone port - limiting audio options for serious videographers.

In contrast, the Pentax H90 records only HD 720p video at 30fps using Motion JPEG - a dated, comparatively large file format with moderate quality. There is no external audio input, no 1080p, and no manual exposure controls during video.

For those prioritizing video alongside photos, the GF7 is the obvious choice.
