Nikon 1 J1 vs Olympus PEN E-PM1: A Thorough Comparison of Two Entry-Level Mirrorless Cameras

Choosing the right camera can be a complex journey, especially when it comes to entry-level mirrorless models that promise ease of use, portability, and creative freedom. Today, I’m diving deep into a side-by-side comparison of two popular early 2010s mirrorless contenders - the Nikon 1 J1 and the Olympus PEN E-PM1. Both aimed at users stepping up from point-and-shoot cameras or smartphones, these models bring their own unique strengths and weaknesses to the table.

I’ve personally tested thousands of cameras over the years, so I’ll be bringing a blend of hands-on experience, technical understanding, and real-world storytelling to help you decide which camera might suit your photography style, needs, and budget best.

Size Matters: Ergonomics and Handling in Everyday Use

Both the Nikon 1 J1 and Olympus PEN E-PM1 sport a compact, rangefinder-style mirrorless design geared for portability - a big plus for street, travel, and casual photography. Handling comfort, however, often comes down to nuanced factors like grip sizing, weight distribution, and control layout.

Nikon 1 J1:
At just 106 x 61 x 30 mm and weighing a mere 234 grams (without lens), the 1 J1 is exceptionally small and light. Its smooth, rounded edges and minimal grip, however, can feel a bit slippery in hand, especially for extended shooting sessions or users with larger hands. The lack of physical depth means you’ll rely heavily on touchscreen controls or menu navigation, which can slow you down.

Olympus PEN E-PM1:
A slightly larger body (110 x 64 x 34 mm) and heftier frame at 265 grams give the PEN E-PM1 a more substantial feel without tipping the scales excessively. The slightly more pronounced grip area adds confidence when holding the camera, helping with stability during handheld shots and flick-quick framing in street photography. Controls tend to be a bit more tactile, aiding those who prefer physical buttons over touchscreen interfaces.

For travel and street shooters prioritizing ultra-compactness, the Nikon 1 J1’s form factor is appealing, but if you value a better handhold and longer comfort, the Olympus PEN E-PM1 is the more ergonomic choice.

Topside Controls: What’s at Your Fingertips

Once you pick up the camera, how the buttons and dials are arranged can drastically influence your shooting flow - especially during fast-paced or dynamic shoots.

I appreciated Nikon’s simplistic top design, keeping the learning curve gentle for beginners. The J1 offers essential controls like a well-placed shutter button and a mode dial for exposure modes - including aperture priority, shutter priority, and full manual. That said, the absence of more physical buttons means some settings require deeper menu dives.

Olympus counters this with a few more external controls, including intuitive exposure compensation and access buttons. Its TruePic VI processor powers a responsive interface, facilitating quicker menu navigation and control adjustments. While neither camera features touchscreens, the PEN E-PM1’s layout felt more inviting to photographers who like to tweak settings on the fly rather than plunging into menus.

For serious shooters or evolving enthusiasts who want faster access to key settings, Olympus has the edge here - but novices might still find Nikon’s simplicity a relief.

Sensor and Image Quality: The Heart of the Camera

A camera’s sensor size, resolution, and processing capability are pivotal for final image quality, dynamic range, noise performance, and versatility across genres like portraits, landscapes, and wildlife.

Nikon 1 J1:
The J1 halved the traditional APS-C or Four Thirds sensor size conversation by featuring a 1-inch CMOS sensor measuring 13.2 x 8.8 mm, delivering about 10 megapixels. While this small sensor contributed to the J1’s diminutive body design, it also constrained low-light performance and depth-of-field control.

Image quality here is decent in bright conditions but begins to degrade noticeably beyond ISO 800, with considerable noise intrusion by ISO 1600 and above. The sensor’s dynamic range and color depth are modest (DXOmark scores: color depth 21.5 bits, dynamic range 11 stops), limiting its prowess in challenging lighting.

Olympus PEN E-PM1:
Olympus’s Micro Four Thirds sensor (17.3 x 13 mm) is roughly double the sensor area of Nikon’s 1-inch chip, with a slightly higher 12 MP resolution. This sensor offers better control over noise, especially in shadows and midtones, and improved dynamic range (DXOmark scores: color depth 21 bits, dynamic range 10.3 stops).

TruePic VI processor optimizes color rendering, offering pleasing skin tones and enhanced detail retention in landscapes and portraits. The PEN’s sensor size - while smaller than APS-C - delivers a satisfying balance between quality and compactness, especially for enthusiasts seeking an upgrade from smartphones or entry compact cameras.

Real-World Insight:
In daylight, both cameras produce clean, vibrant JPGs with good sharpness. That said, the Olympus E-PM1 maintains cleaner shadows and richer tonal gradations in complex lighting - a boon for landscape and portrait shooters chasing subtle details.

Viewing Experience: Screens Over Viewfinders

Both cameras lack built-in electronic viewfinders, relying solely on rear LCD screens for composition, which is standard for their class.

The 3-inch displays on both cameras share similar 460k-dot resolutions, but Olympus’s HyperCrystal LCD features an anti-reflective coating that improves visibility under sunlight. This difference matters when shooting outdoors, particularly during landscapes or street photography where glare can hamper framing speed and accuracy.

Nikon’s fixed TFT LCD, while bright, suffers a bit in harsh light. Neither camera offers a touchscreen interface, which means focus point selection and menu navigation rely on buttons and dials, favoring Olympus’s more intuitive menu system.

If you plan to shoot primarily outdoors or want maximum visibility for quick refocusing, Olympus’s screen is a definite plus.

Autofocus Systems: Speed and Accuracy on Demand

Autofocus is often the unsung hero of camera usability, affecting everything from capturing decisive moments to macro precision and wildlife tracking.

• Nikon 1 J1 boasts a hybrid AF system blending phase-detection and contrast-detection with 135 total focus points, yielding rapid acquisition speeds. However, it lacks continuous autofocus tracking during burst shooting and eye/face detection is not supported.

• Olympus PEN E-PM1 employs contrast-detection only with 35 focus points but benefits from face detection and continuous autofocus during burst capture. However, its single AF sensor type leads to slower focus acquisition in lower light or moving subjects.

From my experience, Nikon's hybrid system works well for static and moderately dynamic subjects, such as portrait sitting or gentle street photography. For fast-moving action like wildlife and sports, the lack of continuous AF during bursts reduces Nikon’s effectiveness.

Olympus's face detection and continuous AF give it an edge in portrait and casual event photography scenarios, especially for quick snapshots where accuracy on faces is crucial. However, its slower AF speed frustrates wildlife and fast-sports shooters more accustomed to snappy focus acquisition.

Burst Shooting and Performance – Catching the Action

Burst rates often determine a camera's suitability for wildlife and sports photography.

• Nikon 1 J1 impresses in this regard with a 10 fps continuous shooting speed, albeit with locked focus after the first frame in continuous mode. Its electronic shutter can go as fast as 1/16000s, great for shooting in bright light or freezing fast action.

• Olympus PEN E-PM1 offers 6 fps burst with continuous AF, providing better tracking during rapid sequences, but the slower speed may limit usability for high-speed subjects.

It’s worth noting neither camera features buffer sizes or rapid write speeds competitive with modern systems, so long burst sessions are limited.

For timed bursts to capture split-second moments, Nikon’s faster frame rate has value, though Olympus’s focus tracking helps ensure more frames are sharp.

Built Quality and Weather Resistance

Neither camera offers weather sealing or ruggedized features, typical within this entry-level bracket. Both bodies are primarily composed of plastics with metal mounts.

If you’re often outdoors shooting landscapes, wildlife, or travel photography in harsh or inclement conditions, be prepared to handle these cameras delicately or invest in protective housing.

Lens Ecosystem and Versatility

Lens availability significantly influences what photography types a camera system can excel at.

• Nikon 1 Series lenses: 13 native lenses are available, covering basics from wide-angle to telephoto zooms and primes. That said, the 2.7x crop factor leads to very tight field-of-view on wide lenses, limiting ultra-wide landscape framing and macro versatility.

• Olympus Micro Four Thirds lens mount boasts a massive ecosystem with over 100 lenses from Olympus, Panasonic, and third-party makers. With a more modest 2.1x crop factor, the FOV matches better with standard lenses, giving better coverage of wide-angle and medium telephoto ranges.

I’ve found that the Olympus MFT system provides greater creative freedom, whether you shoot portraits (fast primes like the 45mm f/1.8), landscapes (wide zooms), or macro (dedicated close-up lenses).

The Nikon 1 system’s smaller sensor and crop factor restrict reach but sacrifice field-of-view, which can frustrate landscape photographers and those hunting shallow depth of field.

Battery Life and Storage

Battery endurance is another practical concern, especially for travel and extended shoots.

• Nikon 1 J1 rated around 230 shots per charge. It uses the proprietary EN-EL20 battery, compact but limited in runtime. For a daylong excursion, carrying spare batteries is essential.

• Olympus PEN E-PM1 offers roughly 330 shots per battery (BLS-5), competitive in its class, giving a longer handheld shooting span. The rechargeable pack is also compact but more accommodating.

Both accept SD/SDHC/SDXC cards in single slots with standard USB 2.0 and HDMI connections.

Video Capabilities: Hybrid Use Considerations

Entry-level mirrorless cameras often appeal to hybrid shooters who want stills and video.

• Nikon 1 J1 records up to 1080p at 60fps using MPEG-4/H.264 compression, delivering relatively smooth footage for its era. However, it lacks microphone input, limiting audio upgrade potential.

• Olympus PEN E-PM1 also records 1080p video, capped at 60fps in AVCHD and Motion JPEG formats. It similarly doesn’t provide external mic or headphone jacks, restricting advanced audio control.

Neither model incorporates in-body stabilization for video, but Olympus’s sensor-based image stabilization can assist with handheld shooting in stills - a valuable aid in low-light situations.

How They Perform Across Photography Genres

Let’s break down their relative merits and limitations across typical usage scenarios, leveraging my personal field tests and objective industry benchmarks.
