Panasonic FX90 vs Pentax Optio P70: An Expert Comparison for Compact Camera Buyers

Choosing the right compact camera can be challenging, especially when models share similar specs but diverge in features and real-world capabilities. Today, we’re diving deep into two small sensor compacts: the Panasonic Lumix DMC-FX90 (henceforth FX90) and the Pentax Optio P70 (P70). Both are fixed-lens cameras announced a couple of years apart: the FX90 in 2011 and the P70 in 2009. Though they target casual photographers and enthusiasts seeking easy portability, there are subtle but important differences impacting performance and usability that can steer your decision.

Having extensively tested thousands of cameras, including many compacts with small sensors, I’ll provide a hands-on, technical, and candid review of both models. Whether you want a pocket-friendly travel shooter, a beginner-friendly every-day camera, or a secondary backup, this comparison will help clarify which suits your needs best.

How Big and Comfortable Are They? Examining Physical Profiles and Handling

Pocketability is critical with compacts. Cameras that are too bulky or awkward discourage daily carrying. Ergonomics also matter if you want to shoot extended sessions comfortably.

The FX90 measures 102 x 56 x 22 mm and weighs 149 g, while the P70’s dimensions are 97 x 54 x 22 mm with a 155 g weight.

Both cameras share a similar slim profile, but the Panasonic FX90 is just slightly larger in length and width. This inch gives the FX90 a somewhat more secure grip, and Panasonic’s design includes a gentle grip contour on the front which aids one-handed stability. Meanwhile, the Pentax P70's more boxy shape means a less ergonomic grip, but it compensates with a compactness that fits very neatly into smaller pockets.

The controls on the FX90 are more spaced out with dedicated zoom and shutter buttons, while the P70 keeps it minimalist with fewer physical controls. If you prefer tactile feedback and manually assisted zooming, the Panasonic’s superior button layout may feel more comfortable under longer use.

At a Glance: Design and Control Layout Differences

Let’s check the control surfaces to understand how straightforward or fiddly the operation feels. This influences usability especially when shooting quickly or changing settings on the fly.

The FX90’s control deck features an on/off switch, zoom toggle, shutter release, and a shutter priority button – even though it lacks full manual exposure modes. The P70 keeps it simpler, with a few more compact buttons but no dedicated zoom lever, relying mostly on the zoom rocker around the shutter button.

Neither camera offers an electronic viewfinder, relying solely on their rear LCD screens, but Panasonic’s touchscreen on the FX90 adds a modern convenience for autofocus point selection and menu navigation, which the P70 does not provide.

Sensor Specs and Image Quality: The Heart of Any Camera

Both the FX90 and the P70 employ a 1/2.3-inch CCD sensor, measuring almost identically at around 6 x 4.5 mm, and each resolves a maximum of 12 megapixels. This sensor size and resolution are pretty standard for compact cameras in their generation.

Key Sensor Insights:

• Both sensors are CCD type, which traditionally excel in color rendition but lag behind CMOS in higher ISO noise performance.
• They both apply an anti-aliasing filter, slightly softening images but reducing moiré artifacts.
• Native ISO maxes at 6400 for both but realistically, usable ISO tops out much lower due to noise.
• Raw shooting isn’t supported on either, limiting post-processing flexibility.

After running side-by-side testing indoors and outdoors, the FX90 generally produces slightly cleaner images at ISO 400 and below. Its newer processing engine helps with minor noise suppression and color accuracy. The P70 tends to exhibit more chroma noise in dimmer scenes, especially above ISO 200.

For landscape, portraits, or daylight street photography, expect similar results at base ISO with sharpness primarily determined by lens quality and shooting technique.

Rear Screen and User Interface: Your Window Into the World

A camera’s LCD screen is your primary interface for composition and settings. Let’s compare both models’ displays:

• Panasonic FX90: 3.0-inch Fixed TFT LCD with 460k-dot resolution, touchscreen enabled.
• Pentax P70: 2.7-inch Fixed LCD with 230k-dot resolution, no touchscreen.

The FX90 offers a significantly clearer, higher resolution touchscreen that responds well for AF point selection and menus. For novices and casual shooters, this is a major usability boost - it can speed up workflows and improve framing accuracy.

The P70’s lower-res screen sometimes appears grainy and struggles under bright sunlight, plus the absence of touch control means using physical buttons for menu navigation, which slows operation.

Lens Capabilities: Zoom, Aperture, and Macro Performance

Both cameras feature integrated zoom lenses ideal for travel and casual shooting:

The FX90’s wider zoom range (24mm ultra-wide to 120mm telephoto) provides greater compositional flexibility. The lens also opens slightly wider at the wide end (f/2.5 vs f/2.8), enabling better low-light capture and a bit more background separation in portraits.

The P70 is at a disadvantage with a narrower zoom range and a longer minimum macro focusing distance (10 cm compared to 3 cm on the FX90). This means if you enjoy close-up flower or insect shots, the FX90 is more capable.

Autofocus and Shooting Performance

Both cameras rely on contrast-detection autofocus - common in compacts at this price point. However, the FX90 has an edge with:

• 23 AF points compared to 9 in the P70
• Touch autofocus on the FX90’s screen
• Continuous autofocus and tracking capabilities on the FX90; limited single AF point on P70

Real-world testing highlights the FX90 as faster and more confident in acquiring focus, especially in moderately low light. The P70 occasionally hunts when detail is low or in filmy lighting, leading to missed shots.

In continuous shooting, the FX90 can capture 4 fps, beneficial for casual action or candid bursts. The P70 does not specify continuous speed, and in practice its buffer and frame rate are limited, making it less suitable for capturing movement.

Build Quality and Durability

Neither camera offers weather sealing or rugged protection. Both lack dustproofing or freezeproofing, so operation in harsh conditions requires caution.

The FX90’s body shows a more robust build with a slight rubberized grip aiding comfort and grip reliability over extended sessions. The P70 is more basic, focusing on minimalism and ultra-compact size. Neither camera has environmental sealing, so they’re best kept dry and clean.

Video Capabilities: Who Wins in Moving Image Capture?

Both cameras offer HD video, but specs and quality differ:

The FX90 clearly outperforms the P70 in video. Its Full HD at 60 frames per second delivers smoother, higher-quality footage, suitable for casual videography or vlogging. Optical stabilization helps keep footage steady.

The P70 maxes out at 720p with just 15 fps, resulting in choppier and softer video. No stabilization further handicaps handheld shooting.

If video recording is part of your creative workflow, the Panasonic FX90 is the superior choice.

Battery Life and Storage

Battery life is essential when traveling or shooting outdoors without immediate access to charging.

• FX90 rated for ~200 shots per battery charge using the proprietary battery pack.
• P70 battery life is unspecified, but similar ultracompacts typically hover between 150-200 shots per charge.
• Both models use SD/SDHC cards with single storage slots.
• FX90 includes USB 2.0 and HDMI connections, as does the P70.
• FX90 supports wireless connectivity (Wi-Fi) for image transfer; P70 has no wireless features.

Wireless connectivity on the FX90 adds convenience for quick sharing. If connectivity is a priority, the P70 falls short.
