Nikon Coolpix P300 vs. Pentax Optio I-10: A Hands-On Comparison of Two Small Sensor Compacts

Choosing a compact camera in the small sensor category can be a balancing act, especially when faced with models like the Nikon Coolpix P300 and the Pentax Optio I-10. Both cameras target enthusiasts craving more control than smartphone shooters but within a pocketable, straightforward form factor. I’ve logged dozens of hours testing each through diverse photographic lenses - from tripod-mounted landscapes to handheld low-light street shots - and in this detailed comparison, I'll share which camera genuinely excels, in what areas, and why.

Let’s deep-dive beyond spec sheets and marketing blurbs, revealing the practical realities that shape your shooting experience.

First Impressions: Size, Ergonomics, and Build Quality

At a glance, both cameras look the part of premium compacts with sleek finishes designed to slip comfortably into a jacket pocket or travel bag. However, there are clear differences once you hold them side-by-side.

The Nikon P300 is slightly thicker than the Pentax I-10 (32mm vs. 28mm) and heavier at 189 grams against 153 grams. This added heft isn't just dead weight; it contributes to a reassuringly solid feel in-hand and a firm grip, despite its diminutive footprint (103x58mm). The P300’s textured front fascia and strategically sculpted grip area allow for more secure one-handed operation, which I appreciated during longer shooting sessions, especially with heavier zoom pulls.

In contrast, the Pentax I-10 offers a flatter, smoother body, closer to a traditional point-and-shoot, measuring 101x65mm. This makes it slightly wider but easier to slip into tight spaces. Its smaller 2.7-inch screen and lighter weight are bonuses for ultra-portability, but the trade-off is a bit less ergonomic comfort during extended handheld use, particularly if you're shooting with intent and precision.

Control-wise, Nikon’s P300 presents a more sophisticated top-plate layout with a dedicated exposure compensation dial and a mode dial supporting manual as well as aperture and shutter priority modes. This immediately signals its inclination toward creative control. The Pentax I-10 dispenses with such dials, resorting to a more menu-driven approach with fewer manual exposure options, reflecting its “point-and-shoot with a twist” ethos.

Bottom line: If you prize thoughtful ergonomics and direct control, the P300 slightly edges ahead in physical design. For grab-and-go simplicity, the I-10 offers a neat, compact package that won’t overwhelm beginners.

Sensor and Image Quality: Two 12MP 1/2.3” Sensors, Worlds Apart

Both cameras pack a 12-megapixel 1/2.3-inch sensor measuring roughly 6.17 by 4.55mm (28.07 mm² sensor area). But here the similarities largely end.

The Nikon P300 sports a backside-illuminated CMOS sensor paired with the Expeed C2 processor, an architecture designed to optimize light gathering and reduce noise. The Pentax I-10 uses an older CCD sensor with the Prime processor. From experience, CCDs tend to offer pleasant color rendition and slightly better dynamic range at low ISOs but falter in high ISO noise control and frame rate capabilities.

• Dynamic Range & Color Depth: The P300’s BSI-CMOS sensor delivers richer color depth and better shadow detail retention. In landscape shooting, I observed deeper, more nuanced greens and subtle tonal gradients in skies when shooting RAW or fine JPEGs, an important deciding factor for nature photographers.

• ISO Handling: The Pentax I-10 claims sensitivity up to ISO 6400 vs. P300’s maximum ISO 3200. However, beyond ISO 800, image noise on the I-10 becomes rather intrusive, characterized by blotchy chroma noise and loss of detail. The Nikon’s sensor handles high ISOs more gracefully, producing cleaner images at ISO 1600 and usable results even up to ISO 3200 - a boon for low light and indoor shooting.

• Resolution & Sharpness: Although both offer 12MP output at 4000 x 3000 pixels, the Nikon’s combination of a sharper lens and anti-aliasing filter results in crisper, more detailed images straight from the camera. The Pentax tends toward softer images with less micro-contrast, which may require additional sharpening in post.

Expert tip: Given their sensor size, neither camera can rival APS-C or full-frame DSLRs in image quality, but for compact sensor compacts, Nikon’s BSI-CMOS sensor yields a noticeable edge in both low light and dynamic range performance.

Autofocus and Exposure Control: Creative Freedom vs. Simplicity

Autofocus systems in compact cameras often determine everyday usability and creative potential.

• Nikon P300 AF System: A 9-point contrast detection system with face detection and AF tracking leads to fairly reliable focusing in a variety of settings. While it lacks phase detection AF (impossible on a fixed lens compact), I observed quick locking in good lighting and minimal focus hunting. Eye detection also helps portrait shooting, ensuring the subject is sharp.

• Pentax I-10 AF System: Also uses 9 contrast detection points, but lacks face and eye detection. Focus speed is slower, and continuous AF doesn’t exist, which made tracking moving subjects challenging in my tests.

Where the Nikon P300 really wins is through manual control - its dedicated exposure modes (P, A, S, M), plus exposure compensation dial, allow photographers to dial in creative settings. This is critical for landscape photographers and anyone who likes shooting in aperture priority or manual mode.

Pentax opts for more limited exposure control - no shutter or aperture priority and no manual exposure modes. It’s very much a point-and-shoot experience with an emphasis on simplicity. The Pentax does, however, feature sensor-shift image stabilization, which sometimes proved helpful for handheld shots.

Lens and Optical Performance: Reach and Brightness

Both models use fixed lenses with optical zoom:

The P300’s fast f/1.8 aperture at wide-angle is impressive for a compact and greatly advantageous in low light and shallow depth of field applications like portraits. Its 24mm ultra-wide focal length also supports expansive landscape compositions.

The I-10’s longer 28-140mm range provides extra telephoto reach, potentially tempting for casual wildlife or distant street shooting. However, the slower aperture, maxing out at f/3.5 wide open, means poorer low-light capability and less control over depth of field. Its macro capability is limited to 10cm, making the P300 better suited to close-up work with a 3cm focus floor.

Optically, Nikon’s construction with an anti-reflective coating reduces flare and ghosting better than Pentax’s design. The image stabilization system differs as well: Nikon uses optical stabilization which directly compensates lens movement, whereas Pentax employs sensor-shift, which moves the sensor itself. Both prove helpful to reduce blur, but the Nikon’s optical IS is usually more effective during zoomed-in shots.

Shooting Modes and Video Performance

Video capabilities in small compacts often take a backseat, but there are meaningful differences.

• Nikon P300 Video: Offers Full HD (1920×1080) recording at 15fps and 30fps frame rates, with H.264 and Motion JPEG compression. It also supports 1280×720 HD at 15, 30, and 60fps and even a 120fps 640×480 slow-motion mode.

• Pentax I-10 Video: Limited to 1280×720 HD at 15 and 30fps and lower resolutions with only Motion JPEG format.

The P300’s higher resolution and multiple frame rates provide greater video versatility. The smooth 30fps 1080p mode is a highlight, though audio quality suffers without a microphone input on either. Neither model supports 4K or advanced stabilization for video, so neither is ideal for professional video workflows.

Battery Life, Storage, and Connectivity

Battery technology can make or break trips and all-day shoots.

• The Nikon P300 relies on an EN-EL12 battery rated for approximately 240 shots per charge - modest but typical for compacts of its time. Its USB 2.0 and HDMI outputs allow tethering and playback.

• The Pentax I-10 uses a D-LI92 battery with no official CIPA rating, but real-world usage suggests slightly shorter endurance. It supports standard USB 2.0. Notably, the Pentax features Eye-Fi wireless card support, which was an innovative niche feature enabling wireless image transfer via special SD cards - a feature the Nikon lacks.

Neither camera has Bluetooth, NFC, or GPS functionality.

Specialized Genres: How These Cameras Perform Across the Board

Understanding how the P300 and I-10 perform in key photography disciplines clarifies their best use cases.

User Interface and Screen

With no built-in viewfinder on either, the rear LCD screen is your primary visual tool. Nikon’s 3-inch, 922k-dot TFT LCD is noticeably brighter and more detailed than Pentax’s smaller, dimmer 2.7-inch 230k-dot screen. This makes framing and reviewing shots easier, especially in bright conditions.

The Nikon’s menu and button layout feel more intuitive and robust, featuring a more granular exposure and drive mode access. Pentax’s interface is pared down, aligning with its simpler feature set but limiting quick adjustments.

Price to Performance: What Are You Really Paying For?

At the time of their release and available street prices - approximately $499 for the Nikon P300 vs. $310 for the Pentax I-10 - one must weigh cost against features.

The P300 steps into a more premium compact territory with enhanced manual controls, better sensor technology, and superior video capabilities. It’s more suited for enthusiasts seeking creative flexibility and higher image quality.

The Pentax I-10 caters to budget-conscious users who desire a capable, lightweight travel camera with solid optics and basic controls, tolerating slower processing and simpler feature sets.
