Panasonic Lumix DMC-FP1 vs. Pentax Optio E85: A Hands-On Ultracompact Camera Comparison for Enthusiasts

When choosing a compact camera that balances portability and everyday performance, enthusiasts often wrestle with models that promise convenience without compromising image quality too much. Today, I take a close, forensic look at two such contenders from the late 2000s / early 2010s era - the Panasonic Lumix DMC-FP1 and the Pentax Optio E85. Both offer fixed-lens companionship with modest zoom ranges, aimed at casual to enthusiast users seeking compactness.

Having personally tested thousands of cameras, including these, I’ll guide you through a thorough comparison based on real-world usage, technical testing, and practical photography needs. We'll cover everything from sensor technology to ergonomics, and assess their strengths and limitations across various photography genres.

Here you can see the physical differences between the compact Panasonic FP1 and Pentax E85 - notice their similar footprint but distinct body thickness profiles.

Starting with Build and Handling: How Comfortable Are They in Your Hands?

Both cameras are very compact, designed primarily for casual carry, which is evident in their small physical sizes.

• Panasonic FP1: Measures 99x59x19 mm, weighing about 151g. Its slim profile is friendly for pockets and purses.
• Pentax E85: Slightly smaller footprint at 93x58 mm but thicker at 24 mm, weighing 145g.

The Panasonic, thanks to the thinner body, feels sleek but less substantial in the hand, whereas the Pentax, though chunkier, offers a somewhat better grip surface. Both cameras lack any rubberized or heavily contoured grips, so prolonged shooting can feel a bit precarious, especially for users with larger hands.

Neither camera includes a viewfinder or touchscreen, which is common for this category but somewhat limits framing flexibility in bright conditions. Instead, both rely solely on a 2.7-inch fixed LCD for composing shots.

Here’s a look from above showing the button and dial placement - note the minimalist control scheme on both models.

Controls and usability:

• Both models use a simplistic control layout with basic mode dials and buttons.
• Neither supports manual exposure modes or aperture/shutter priority - meaning all exposure adjustments are automatic. This simplicity suits beginners but may frustrate enthusiasts craving creative control.

Summary: Ergonomically, both are pocket-friendly but lack advanced handling features. The Pentax’s thicker body slightly improves grip, while Panasonic’s slender design edges out on portability.

Sensor and Image Quality Deep Dive: What’s Under the Hood?

Both cameras sport a 1/2.3-inch CCD sensor at 12MP resolution - a typical specification for compacts of this generation. Pixel counts are identical at 4000x3000 pixels, offering standard detail levels suitable for prints up to 8x10 inches.

Comparing sensor sizes and key specifications shows near parity, though the Pentax sensor has a marginally larger active area.

Panasonic FP1 Sensor Notes:

• 27.72 mm² sensor area.
• Max ISO 6400 (native start at 80).
• Uses Panasonic’s Venus Engine IV processor for image rendering and noise reduction.
• Optical image stabilization assists in reducing blur during handheld shots.

Pentax E85 Sensor Notes:

• Slightly larger sensor area at 28.07 mm².
• Max native ISO of 3200, lower ceiling than Panasonic.
• No built-in image stabilization.
• Color depth and dynamic range are broadly comparable given similar sensor tech, but image noise is slightly better handled on the Pentax at lower ISO levels.

Resolution and Detail:
Both cameras deliver sharp detail at base ISO, although the Panasonic’s stabilizer helps reduce motion blur in slower shutter speed situations. In practice, the Pentax can sometimes edge out slightly crisper images due to a less aggressive noise reduction pipeline, but both struggle with noise beyond ISO 400.

Color Rendering and Bit Depth:
Neither camera offers RAW file support, limiting post-processing flexibility. JPEGs rely on in-camera processing - Panasonic’s Venus engine tends toward punchier colors but sometimes over-processing, while Pentax’s results look more natural albeit a bit flat.

Summary: For casual shooting, both cameras offer decent image quality; Panasonic is better for handheld low-light usability, while Pentax has better base ISO noise performance. Neither matches modern sensor capabilities but hold their own for snapshot quality.

Autofocus Systems: Speed, Accuracy & Usability in Various Conditions

Both cameras rely on contrast-detection autofocus, standard for compacts of the era, but do not offer phase detection or hybrid AF systems seen on more advanced models.

• Panasonic FP1: 9 autofocus points. No face or eye detection. Offers 'multi-area' AF, which attempts to pick the subject in the frame.
• Pentax E85: AF points not specified, generally employs a center-weighted approach with spot AF available. No face tracking.

Focus speed is modest on both but noticeably slower in dim light or low-contrast scenes. Neither camera supports continuous AF tracking for moving subjects, impairing performance for action or wildlife shooting. Single-shot focus is accurate for stationary subjects with sufficient lighting.

My testing confirms:

• The Panasonic autofocus is somewhat quicker on daylight scenes, but hunting in low light remains a problem with visible delay.
• Pentax’s AF felt slightly more deliberate but consistent under good lighting.

Neither camera supports manual focus or focus bracketing, which limits control for macro or selective focus techniques.

Screen and User Interface Experience: Framing and Preview Capabilities

Both cameras share a 2.7-inch fixed LCD with 230k pixel resolution, enough for basic framing and image review, but lacking crispness and dynamic brightness range compared to contemporary standards.

The screens provide similar viewing experiences, with limited viewing angles and no touch support.

• No articulation means less flexibility for low or high-angle shooting.
• No electronic viewfinder means relying solely on the screen outdoors - which can be challenging in bright sunlight.
• Interfaces are straightforward but bare-bones, offering limited exposure adjustment options (e.g., no manual mode or advanced bracketing).

Summary: If you rely heavily on screen sharpness and flexible viewing, neither camera excels, but they get the job done for casual snapshot needs.

Lens and Zoom: Focal Ranges and Aperture Flexibility in Everyday Use

Both cameras come with fixed zoom lenses, limiting versatility but simplifying usage.

• Panasonic FP1: 35-140mm equivalent zoom (4x zoom), aperture F3.5-5.9.
• Pentax E85: 32-96mm equivalent (3x zoom), aperture F2.9-5.2.

The Pentax lens is brighter at wide-angle (F2.9 vs. F3.5), which can improve low-light and depth-of-field control. The Panasonic offers a greater telephoto reach, better for portraits or distant subjects, but at a slower aperture.

Notably, neither camera offers manual aperture control, so the lens choice mainly affects inherent depth of field and light gathering rather than creative control.

Macro Focus: Both cameras focus down to approximately 10 cm, allowing close-up shots, but neither provides focus stacking or specialized macro modes.

Image Stabilization and Shutter Speed Range: Controlling Movement and Exposure

• Panasonic FP1 includes optical image stabilization, a crucial advantage for handheld shooting at slower shutter speeds or longer focal lengths. This helps combat blur significantly.
• Pentax E85 does not have stabilization, increasing the chance of image blur at low light, especially beyond 1/30 second shutter speeds.

Shutter Speed:

• Panasonic FP1: 1/60 to 1/1600 sec. Minimum shutter speed is relatively fast, which may limit long exposures.
• Pentax E85: 2 to 1/2000 sec shutter speed range offers greater flexibility for longer exposures but lacks stabilization for handheld use.

Video Capabilities: How Do They Stack Up for Casual Videography?

Neither camera focuses on video functionality but supports some basic modes.

• Panasonic FP1 records HD video (1280x720 at 30 fps) - quite forward-thinking for its time.
• Pentax E85 limits video resolution to 640x480 pixels at 30 fps, quite basic by modern and even contemporaneous standards.

Both utilize Motion JPEG compression, limiting file efficiency and editing flexibility. Neither supports external microphones, headphones, 4K, or advanced stabilization features in video.

Summary: Panasonic offers a clear advantage for casual HD video shooters.

Battery Life, Storage, and Connectivity: Practical Day-to-Day Considerations

Battery life is not officially specified for Panasonic FP1; Pentax E85 uses the D-LI95 rechargeable lithium-ion battery.

• Both cameras accept SD/SDHC cards and have a single memory card slot.
• No wireless or Bluetooth connectivity on either model, so image sharing relies on USB transfers.
• USB 2.0 ports enable reasonably fast downloads but no direct camera control from computers.

The Pentax’s dedicated battery facilitates easy replacement or spares, while the Panasonic’s battery type is unspecified in specs, potentially limiting convenience.
