In today’s ultra-portable camera market, the Pentax P70 and Samsung ST700 represent two interesting ultracompact options. Both target casual shooters who want convenient pocket-sized gear without sacrificing basic capabilities. But which one stands out in terms of real-world performance, image quality, and versatility? As someone who has extensively tested hundreds of compact cameras, I’ll walk you through an in-depth, hands-on comparison across various photography disciplines, technical features, ergonomics, and value.

By the end, you’ll not only understand how these models stack up against each other - you’ll also know which one aligns best with your photographic goals and style.

First Impressions: Design, Handling, and Build

When evaluating ultracompact cameras, size and ergonomics directly affect usage comfort and portability. The Pentax P70 and Samsung ST700 are similar in footprint but have subtle distinctions worth noting.

• Pentax P70: Measuring 97x54x22 mm and weighing 155 g, the P70 offers a comfortable grip for an ultracompact. The slightly thicker body provides better handhold security, especially for users with larger hands.
• Samsung ST700: Slightly wider but slimmer at 99x55x20 mm, the ST700 is a bit more pocket-friendly but can feel a bit less hand-assuring. Its weight wasn’t specified, but from handling, I found it marginally lighter.

In terms of control layout, neither camera offers dedicated dials for aperture or shutter speed - unsurprising for this class - but the P70 has manual focus capability, a rarity among basic ultracompacts. It also features a handy 3.9x zoom lens with aperture range F2.8-5.0, while the Samsung’s lens details are less explicit but offer a focal length multiplier of 5.8x similar to Pentax.

The Samsung wins a slight edge with its 3.0-inch touchscreen LCD, a boon for novices used to smartphone-style interfaces, whereas the P70 relies on a smaller, non-touch 2.7-inch screen.

User interface is vital for quick adjustments and checking shots on the go. The Samsung’s higher resolution and touchscreen offer faster, more intuitive operation during live view and review. The Pentax’s screen, while fixed and lower resolution (230k dots), remains adequate though less responsive.

Sensor Technology: The Heart of Image Quality

Your photos’ final quality hinges primarily on sensor technology, size, and resolution. Both cameras employ 1/2.3-inch CCD sensors - standard in ultracompacts - but differ in resolution and sensor area slightly.

The Samsung ST700’s 16MP sensor offers a higher pixel count on a similarly sized sensor area, pushing pixel density beyond the Pentax’s 12MP. In theory, this means sharper images but also potentially more noise at high ISO settings due to smaller pixel wells.

From hands-on testing, I found both cameras suffer from noise creeping in above ISO 800, which is typical for CCD sensors of this era and size. The Pentax P70’s max ISO rating of 6400 is more of a marketing figure; usable image quality declines sharply past ISO 800. Samsung doesn't specify max ISO, but noise performance was comparable.

Neither camera processes RAW files, limiting post-processing flexibility - a significant drawback for advanced photographers wanting maximum image control.

Autofocus and Focusing Capabilities

Fast and accurate autofocus (AF) is essential, even more so in point-and-shoot cameras where spontaneous moments demand instant capture.

The Pentax P70 offers contrast-detection autofocus with 9 points and manual focus capability. This manual focus option is a rare but welcome feature in ultracompacts, allowing careful focus zones for macro or creative shots.

Conversely, the Samsung ST700’s AF specifics are less comprehensive, but reports and sample tests indicate simpler AF without manual overrides.

In real-world street and wildlife shooting tests, neither camera excels due to lacking continuous AF and face detection. The autofocus is slower and less reliable under low light or fast-moving conditions, as expected for entry-level ultracompacts.

Image Stabilization and Exposure Features

Both cameras lack built-in image stabilization (IBIS), which can impact sharpness in low light or telephoto shots.

• Pentax P70: No optical or sensor stabilization is present, so using a tripod or high shutter speeds is advisable.
• Samsung ST700: Similarly no stabilization features.

Exposure controls are also basic:

• No shutter or aperture priority modes; no manual exposure controls.
• Pentax offers custom white balance; Samsung does not.
• Flash ranges vary, but both have built-in flashes adequate for indoor fills within short distances.

These limitations confirm that neither camera targets enthusiasts who prefer creative exposure control - but rather casual photographers focused on convenience.

Video Recording Capabilities

Video features in compact cameras can be a deciding factor for many users.

• Pentax P70: Maximum video resolution is 1280×720 pixels at only 15 frames per second, using Motion JPEG format. This low frame rate results in choppier playback and less smooth motion rendering.
• Samsung ST700: Also maxes out at 1280×720 resolution but frame rate specifics are unclear.

Neither camera supports external microphones or headphone jacks, limiting audio quality and monitoring options for serious videographers.

Overall, video capabilities are basic, primarily suited for casual clips rather than high-quality productions.
