Choosing the right camera is rarely straightforward, especially when options span from compact point-and-shoots to entry-level mirrorless systems. The Olympus PEN E-PL6 and the Pentax Optio RS1500 exemplify these two distinct categories, each tailored for specific user needs and photographic ambitions. I’ve personally tested both extensively across various scenarios, and this comparison aims to give you an honest, thorough, and practical guide to decide which camera fits your photography style, skill level, and budget.

Let’s dive deep into how these cameras stack up in body design, image quality, autofocus, shooting performance, and genre-specific applications so you can buy with confidence.

First Impressions: Size, Handling, and Controls

Understanding a camera’s ergonomics is more than just “how it feels in the hand.” It often dictates your shooting comfort and quick access to essential controls - factors crucial in fast-paced or creative environments.

Size and Ergonomics

The Olympus E-PL6 is a compact entry-level mirrorless with a classic rangefinder-style body measuring 111x64x38 mm and weighing approximately 325g. Its lightweight design coupled with a tilting 3-inch touchscreen makes it surprisingly pocketable while offering better grip and control than most compact cameras.

In contrast, the Pentax RS1500 is an ultra-slim 114x58x28 mm, 157g compact, more akin to a high-end point-and-shoot. Its size enables ultimate portability and discretion but at a cost - smaller controls and fewer physical buttons.

Control Layout and User Interface

The Olympus’s control layout reflects its “mirrorless” pedigree with dedicated dials for shutter speed, exposure compensation, and mode selection – a boon for photographers who want quicker manual adjustments. The touchscreen interface complements these with swift menu navigation, focusing, and aperture control.

The Pentax opts for a more pared-down design lacking manual exposure modes, focusing mainly on simplicity. Buttons are tiny and can be fiddly for users with larger hands or those wearing gloves.

Summary: If you’re prioritizing tactile controls and a flexible interface for varied shooting styles, the E-PL6’s handling will suit you far better. Pentax RS1500 excels in ultra-compact portability and ease of use, ideal for casual snapshots or travel when size is paramount.

Sensor and Image Quality: The Heart of the Matter

The sensor defines what you can achieve creatively. Sensor size, resolution, and processing all influence sharpness, dynamic range, noise handling, and color reproduction.

Sensor Technology and Resolution

• Olympus E-PL6: 16 MP Four Thirds CMOS sensor (17.3 x 13 mm, sensor area ~224.9 mm²)
• Pentax RS1500: 14 MP 1/2.3” CCD sensor (6.17 x 4.55 mm, sensor area ~28.1 mm²)

The Olympus’s significantly larger Four Thirds sensor provides a real advantage in image quality metrics. Larger sensors typically deliver improved dynamic range, finer detail, and better high ISO performance due to physically larger photodiodes.

Pentax's sensor is roughly eight times smaller in area, which inherently limits noise performance and low-light capability but allows greater compactness of the camera.

Image Processing and ISO Range

Olympus incorporates the TruePic VI image processor, handling JPEG processing and noise reduction intelligently, enabling a native ISO range from 100 up to 25600. This makes it versatile for daylight and dim environments.

Pentax RS1500 offers ISO 80 to 6400 with a classic CCD sensor but lacks advanced noise reduction or RAW support, limiting post-processing flexibility.

Real-World Image Samples

In daylight, both cameras produce acceptable images with accurate colors. However, Olympus’s images reveal better clarity on fine details (like foliage and textures) due to the larger sensor and superior glass available via Micro Four Thirds lenses.

Pentax images tend to be softer with more noticeable noise creeping in at ISO 400 and above. Look carefully at shadow areas; the E-PL6 delivers deeper dynamic range retaining highlight details better.

Summary: For photographers seeking superior image quality and post-processing options, the Olympus E-PL6’s sensor technology is the clear winner. The RS1500 is serviceable for casual photographers who want convenience over image excellence.

Autofocus Systems: Hunting Speed and Accuracy

Autofocus (AF) prowess can make or break your shooting experience, especially in fast or unpredictable scenes like wildlife, sports, or street photography.

Focus Modes and Points

• Olympus E-PL6: Contrast-detection AF with 35 focus points, face detection, AF tracking, and continuous autofocus during video.
• Pentax RS1500: Contrast-detection AF with 9 points, no face/eye tracking, and basic single AF.

Given these specs, the E-PL6’s autofocus system is naturally better suited for dynamic compositions. Face detection and continuous tracking enhanced my ability to lock focus on human subjects or moving animals during hands-on testing.

AF Speed and Reliability

The E-PL6 focuses reliably in good light, locking focus swiftly even in moderately low-light indoor settings - albeit not as fast as hybrid phase-detection systems in higher-end cameras. The Pentax, limited by fewer AF points and older tech, hunts noticeably more, slowing your shooting rhythm.

Summary: The Olympus E-PL6’s autofocus flexibility outperforms the RS1500’s basic system in speed and reliability, making it the pragmatic choice for portraits, wildlife, and action shots.

Build Quality and Weather Resistance

Durability is essential if you shoot outdoors extensively or in challenging environments.

• Olympus E-PL6: Plastic body without weather sealing.
• Pentax RS1500: Compact plastic body with environmental sealing (though not waterproof).

Pentax’s sealed construction is rare among compacts and means it can better resist dust or moisture - a plus for travelers hiking or urban explorers shooting in inclement weather. However, neither is rugged or freezeproof for serious adventure photography.

Summary: For rough weather conditions, Pentax RS1500 has a slight edge in protection despite its age. Olympus E-PL6 is designed more for controlled environments or casual outdoor use.

Shooting Performance: Burst Rates, Video, and Other Features

Continuous Shooting

• Olympus E-PL6 offers up to 8 frames per second in burst mode.
• Pentax RS1500 caps at 1 frame per second, severely limiting action photography.

In practice, the E-PL6’s higher burst rate means better chances to capture fleeting moments in sports or wildlife.

Video Capabilities

• Olympus shoots Full HD 1080p video at 30fps with MPEG-4 or Motion JPEG.
• Pentax maxes out at 720p HD, also in Motion JPEG.

While not professional video tools, the Olympus provides higher resolution footage and a built-in image stabilizer that makes handheld shooting smoother.

Stabilization

The Olympus offers sensor-based image stabilization, which I found useful when shooting handheld in low light or telephoto focal lengths. Pentax lacks any form of stabilization.

Connectivity and Storage

• Olympus includes Eye-Fi wireless card compatibility and HDMI output.
• Pentax lacks wireless features but also has an HDMI port.

Both use SD/SDHC/SDXC cards, but Olympus stores RAW files, expanding post-processing capabilities. Pentax only shoots JPEG.

Battery Life

• Olympus claims about 360 shots per charge
• Pentax around 260 shots

Neither is stellar but sufficient for casual or semi-serious use. Olympus’s mirrorless design generally requires more power, yet offers a slight edge here.
