Panasonic Lumix FP5 vs. Pentax ist DL2: A Practical Comparison to Guide Your Next Camera Purchase

Choosing the right camera, especially when balancing diverse photographic needs and budgets, can be challenging. Today, I’m putting two very different but interesting cameras head-to-head: the Panasonic Lumix FP5 ultracompact versus the Pentax ist DL2 advanced DSLR. Through extensive hands-on testing and industry-standard evaluation criteria, I’ll break down every relevant aspect you should consider - from image quality and autofocus, to ergonomics and specialized photography use cases.

Whether you’re a casual enthusiast or a pro exploring an affordable backup, this article will help you understand how these two cameras differ in real-world performance and where each shines. Let’s dive in.

Understanding the Form Factor: Compact Convenience vs. DSLR Control

At first glance, the Panasonic FP5 and Pentax ist DL2 could hardly be more different in size and handling philosophy.

• The FP5 is a tiny ultracompact, designed for ultimate portability with a fixed lens and simple controls.
• The ist DL2 is a mid-sized DSLR, with full manual controls, interchangeable lenses, and robust handling meant for more serious photographic work.

From my experience testing hundreds of models, I can confirm that the FP5’s pocketable dimensions (101x59x18 mm) and weight (141 g) make it ideal for travel, street photography, and situations where you want minimal gear. The flip side is it lacks physical controls and advanced handling features.

Meanwhile, although heavier at 565 g and notably thicker (125x93x66 mm), the Ist DL2’s DSLR ergonomics provide a secure grip and tactile control - perfect for those who prioritize manual settings and lens versatility. This size difference also impacts your shooting style: the FP5 encourages fast snapshots whereas the ist DL2 facilitates deliberate, composed shooting.

Top-Down Controls: Intuitive or Minimalist?

How a camera feels in the hand and what controls are immediately accessible impacts your ability to work efficiently.

The Pentax ist DL2 benefits from a traditional DSLR top plate featuring dedicated dials for shutter speed, exposure compensation, and various shooting modes like shutter priority (S), aperture priority (A), and manual (M). In my time using Pentax DSLRs, such controls empower quick changes without diving into menus - a key factor for dynamic shooting.

Conversely, the FP5 adopts minimal physical buttons with a touchscreen TFT LCD as the primary interface. While innovative in 2011 for an ultracompact, this touchscreen’s small size and 230k resolution limit responsiveness and outdoor usability. The lack of aperture or shutter priority modes further restricts advanced exposure control.

For users accustomed to DSLR-style control, the ist DL2 offers much more ergonomic finesse.

Sensor and Image Quality: Compact Sensor vs. APS-C DSLR

A camera’s sensor lies at the heart of its imaging capabilities. Let’s look at the technical specs and real-world outcomes.

• Panasonic FP5: 1/2.3" CCD sensor, 14 megapixels, max ISO 6400
• Pentax ist DL2: APS-C CCD sensor (23.5x15.7mm), 6 megapixels, max ISO 3200

While the FP5 boasts higher resolution on a very small sensor, real-world image quality is governed not just by megapixels but sensor size, pixel pitch, and signal-to-noise ratio.

From my testing, the Pentax APS-C sensor delivers superior dynamic range (DxO mark score 11.1 vs. untested for FP5), color depth (22.9 bits), and low-light performance (ISO 639 score). The large sensor area captures more light, rendering smoother gradients, cleaner shadows, and less noise at higher ISOs.

The FP5’s smaller sensor results in limited dynamic range and noticeable noise beyond ISO 400–800, making it less suitable for demanding conditions.

Display and Viewfinder Experience

User interface clarity is essential for composing and reviewing images.

The FP5 uses a 3" fixed TFT touchscreen LCD with 230k resolution. It’s easy to navigate basic menus and focus with touch, but the screen’s low resolution shows visible pixelation and struggles outdoors in bright sunlight.

The ist DL2 offers a smaller 2.5" non-touch LCD at 210k resolution, but compensates with an optical pentaprism viewfinder covering 95% of the frame at 0.57x magnification - an essential advantage for precise framing and tracking in various lighting.

For critical framing and action photography, I consistently find optical viewfinders more reliable and immersive, making the ist DL2 preferable here.

Autofocus and Shooting Speed: Precision Matters

The speed and accuracy of autofocus (AF) systems dramatically affect success in moving subjects or low light.

• FP5 autofocus: Contrast-detection with 11 points, face detection, but no manual focus, no continuous AF, and limited tracking.
• Pentax ist DL2 autofocus: Phase-detection with 5 points, manual focus enabled, continuous AF present, but no face detection.

From field tests:

• The Pentax ist DL2’s phase-detection AF is notably faster and more accurate for sports, wildlife, and action photography, particularly in decent light.
• The FP5’s contrast-detection AF can hunt, especially in low light or low contrast situations.
• Lack of manual focus on the FP5 is limiting if you want creative control or macro precision.

Continuous shooting also favors the DSLR: up to 3 fps versus 6 fps for FP5, but DSOs have a smaller buffer and slower write speeds; the FP5’s 6 fps are with limited shot capacity.

Build, Weather Sealing, and Durability

Neither camera offers environmental sealing or rugged protection, reflecting their respective class and release dates.

The Pentax ist DL2, while not weather-sealed, has a robust metal chassis typical of DSLRs, giving it higher durability in normal use and rough handling I encountered during fieldwork.

The FP5’s plastic ultracompact body prioritizes lightweight convenience over ruggedness, so be cautious in extreme weather or impact-prone scenarios.

Lens Ecosystem and Compatibility

Lens options expand creative possibilities tremendously.

• The Pentax ist DL2 uses the Pentax KAF mount, compatible with a large lineup of 151 lenses - including affordable primes, macro, telephoto, and specialty glass.
• The FP5 features a fixed 35-140mm equivalent zoom with modest aperture F3.5-5.9 and no lens interchangeability.

If you’re aiming for specific genres like portraiture with creamy bokeh, macro, or wildlife telephoto reach, the Pentax DSLR offers undeniable versatility.

Battery Life and Storage

Battery endurance and storage media impact extended shoots.

• FP5 uses a lithium battery pack with an official rating of 260 shots per charge - typical for compact cameras with power-hungry LCDs.
• The Pentax ist DL2 runs on 4 x AA batteries, which offer flexibility in field replacement but generally have shorter life and more weight. Exact shot count data is sparse but expect around 300-400 shots depending on battery type and usage.

Both cameras use standard SD cards, though the Pentax supports SD/MMC and the FP5 supports SD/SDHC/SDXC, handy for larger storage.

Connectivity and Extras

Neither camera offers modern wireless features like Wi-Fi or Bluetooth. The FP5’s USB 2.0 port is faster than the ist DL2’s USB 1.0 for image transfer, but both will be relatively slow by today’s standards.

Neither has GPS, HDMI, or external microphone inputs, and video capability is limited:

• FP5 records HD video at 1280x720p @ 30fps in Motion JPEG format - suitable for casual video.
• The ist DL2 has no video recording.
