The PEN-F offers a traditional Micro Four Thirds mirrorless experience with a stylish, rangefinder-inspired design, targeting photographers who prize image quality and creative control. In contrast, the Stylus 1s aims at versatility and convenience, encapsulated in a bridge camera body featuring a fixed superzoom lens. Both have loyal followings, yet a thorough, technically grounded comparison is essential for any serious buyer evaluating their utility across diverse photographic disciplines.

This comprehensive analysis examines the PEN-F and Stylus 1s from multiple angles, drawing on extensive hands-on testing methodologies used over the past 15 years with digital mirrorless and bridge cameras. The goal is to equip photography enthusiasts and professionals with the nuanced understanding needed to confidently select the model that aligns with their shooting style, budget, and workflow requirements.

Form Factor and Ergonomics: Rangefinder Charm Meets Superzoom Practicality

The Olympus PEN-F embodies classic rangefinder visual cues with a contemporary twist. Its compact, slim body measuring 125x72x37mm and weighing 427g strikes a balance between portability and control. The body includes a fully articulated 3.0-inch touchscreen LCD with 1,037k dots resolution, facilitating versatile shooting angles and touch-based focusing or menu navigation. The layout favors tactile dials and buttons over menus, appealing to photographers who prefer mechanical, direct control during shoots.

Conversely, the Olympus Stylus 1s adopts a bridge camera silhouette reminiscent of an SLR but with a fixed, extensive zoom lens (28-300mm equivalent, f/2.8 constant aperture). It measures 116x87x57mm and weighs slightly less at 402g. Its ergonomics emphasize an integrated superzoom at the cost of bulkier depth and grip size, with a tilting 3.0-inch touchscreen LCD closely matching the PEN-F's resolution at 1,040k dots. The Stylus 1s incorporates a built-in flash, unlike the PEN-F, which requires an external flash for additional lighting.

The PEN-F's approach prioritizes refined manual handling and interchangeable lenses, whereas the Stylus 1s bets on all-in-one convenience and reach. Users valuing discrete carry and fine operational feel will lean towards the PEN-F, while those seeking a versatile zoom range without lens swapping will appreciate the Stylus 1s form factor.

Sensor Technology and Image Quality: Micro Four Thirds vs 1/1.7-inch BSI-CMOS

A pivotal decision point lies in the fundamentally different sensor architectures powering these cameras. The Olympus PEN-F is equipped with a 20-megapixel Four Thirds sized CMOS sensor measuring 17.3 x 13 mm, with an anti-aliasing filter in place. This larger sensor area of approximately 224.9 mm² substantially outperforms the Stylus 1s's 12-megapixel 1/1.7-inch BSI-CMOS sensor sized 7.44 x 5.58 mm (ca. 41.5 mm²), a difference of over fivefold in sensor area.

This sensor disparity translates into key image quality differentiators. The PEN-F's sensor delivers increased dynamic range (12.4 EV measured by DxO Mark) and superior color depth (23.1 bits), allowing for richer gradations in shadow and highlight details, finer color rendition, and more latitude for post-processing. High ISO performance is similarly advantaged, with the PEN-F's native ISO range extending from 200 to 25,600 and a DxO low-light ISO rating of 894, compared to the Stylus 1s's ISO 100 to 12,800 native range and untested DxO score.

Resolution-wise, the PEN-F’s maximum output of 5184 x 3888 pixels at a 4:3 aspect ratio allows for cropping flexibility and large print production. The Stylus 1s offers a maximum of 3968 x 2976 pixels, sufficient for general use but less accommodating for heavy enlargement or professional-level cropping.

Notably, the PEN-F sensor includes an anti-aliasing filter that slightly softens fine detail for moiré suppression but maintains excellent sharpness suitable for most photography needs. The Stylus 1s’s smaller sensor, while benefiting from backside illumination (BSI) to boost sensitivity, inherently sacrifices image quality in terms of noise and dynamic range, especially visible in demanding lighting scenarios.

Autofocus Systems: Precision vs Coverage

The PEN-F employs Olympus’s 81-point contrast-detection autofocus system with comprehensive face detection, continuous AF, tracking, and selective AF modes. Its AF system benefits from on-sensor phase autofocus pixel arrays absent here but still achieves reliable focusing accuracy and speed in various lighting. Autofocus during live view and video recording retains strong responsiveness, though in very low light some hunting can occur.

The Stylus 1s implements a 35-point contrast-detection AF configuration with face detection active and multi-area focusing modes. While its contrast-detection AF system performs well within its category, it lacks the greater number of focus points seen on the PEN-F and does not include advanced animal eye AF features.

In practical terms, the PEN-F shines in applications demanding precise focus control, such as portraiture with eye detection and macro photography. The Stylus 1s autofocus is optimized for rapid acquisition over a wide zoom range rather than pinpoint precision.

Continuous Shooting and Shutter Performance

Burst shooting capability is a significant consideration for dynamic subjects. The PEN-F offers up to 10 frames per second with the mechanical shutter and 1/8000s maximum speed, extendable to a silent electronic shutter mode with speeds up to 1/16,000s for discrete shooting in bright conditions. These options provide flexibility in sports, wildlife, and street photography.

By contrast, the Stylus 1s maxes out at 7 frames per second, with a slower maximum shutter speed of 1/2000s. The lack of an electronic shutter mode limits utility in ultra-bright or silent shooting scenarios.

Practitioners requiring high-speed capture and shutter versatility gain pronounced benefits from the PEN-F platform.

Build Quality and Environmental Resistance

Neither camera offers weather sealing or robust environmental protections. Both lack dustproofing, waterproofing, shockproofing, and freezeproofing features, limiting their use in harsh outdoor conditions without protective housing. The PEN-F, with its rangefinder-style body, employs a magnesium alloy chassis lending a premium feel and durability, while the Stylus 1s uses predominantly polycarbonate construction to maintain affordability and weight control.

For professional or rigorous outdoor usage, these factors may necessitate protective accessories or influence decisions toward other bodies in the Olympus lineup.

Lens Ecosystem and Versatility

Arguably the PEN-F’s most significant advantage is its Micro Four Thirds lens mount compatibility. With over 107 native lenses available covering every photographic niche - from ultra-wide to super-telephoto, primes to zooms - it supports long-term system expansion.

The Stylus 1s’s lens is fixed: a versatile 28-300mm equivalent zoom with a generous constant f/2.8 aperture. While this superzoom offers convenience, it constrains users to its focal range and image quality parameters set by the integrated optics.

Photographers invested in optical customization, lens accessories, or particular portrait and landscape optics will find the PEN-F’s interchangeability indispensable. In contrast, the Stylus 1s suits users prioritizing portability and all-in-one operation.

Viewfinder and Rear LCD Interface

The Olympus PEN-F incorporates a high-resolution electronic viewfinder (EVF) with 2,360k dots, 100% coverage, and 0.62x magnification, delivering a crisp, detailed framing experience, essential for bright environments where LCD visibility can be challenging.

The Stylus 1s houses a smaller EVF with a lower resolution of 1,440k dots, offering similar coverage but less detail and magnification, which can impact manual focusing precision and exposure assessment.

Both have 3-inch rear LCDs with touch capability; the PEN-F features a fully articulated screen, enhancing ease in low-angle or overhead shooting, whereas the Stylus 1s’s screen tilts but lacks full articulation, slightly limiting shooting flexibility.

Image Stabilization and Low-Light Performance

The Olympus PEN-F includes sensor-shift five-axis image stabilization effective across all Micro Four Thirds lenses, delivering sharper handheld shots in low-light, macro, and telephoto conditions. This IBIS (In-Body Image Stabilization) system is a highly regarded feature in professional and enthusiast circles.

The Stylus 1s employs optical image stabilization integrated within its lens system, which is well tuned for the superzoom range but cannot match the broad applicability or micro-movement compensation of IBIS.

Low-light ISO performance follows sensor size trends: the PEN-F sustains cleaner images up to ISO 3200 and useable up to higher ISOs, while the Stylus 1s detects more noise and reduced dynamic range under similar lighting.

Video Capabilities: Full HD Then and Now

Video resolutions on both cameras are limited to Full HD 1080p with the PEN-F able to record at up to 60p and the Stylus 1s capped at 30p. Neither support 4K video or advanced video autofocus technologies, signaling their origins pre-4K era.

Both cameras lack microphone and headphone jacks, restricting audio recording control. Video codecs include MPEG-4 and H.264, adequate but uninspiring.

The PEN-F’s stronger AF system and sensor size provide cleaner video imagery with finer detail, making it preferable for hybrid shooters prioritizing still and video quality balance.

Battery Life and Data Storage

The Stylus 1s offers an advantage in energy efficiency with a rated 450 shots per charge using the BLS-50 battery, compared to the PEN-F’s more moderate 330 shot rating on the BLN-1 battery.

Both utilize a single SD/SDHC/SDXC card slot without dual-slot redundancy - typical for their classes - and connect via USB 2.0 and HDMI for data transfer and external outputs. Wireless connectivity is built-in but constrained to Wi-Fi only; neither camera supports Bluetooth or NFC.
