Launch and Positioning
On September 9, 2026 OM System announced the new OM System PEN, the first camera to carry the historic PEN name under the OM System banner. Priced at $999 (?£850/CA$1,399) for the body only, it uses the same unstacked 20.4 MP Micro Four Thirds sensor and TruPic IX processor found in the OM-5 Mark II. It adds an IPX1 splash-proof rating and a 5.5-stop in-body image stabilization (IBIS) system—features rarely seen together in the sub-$1,000 mirrorless segment.
Background & Context
The PEN series began with a 1959 film camera and later gained a cult following with digital models such as the 2016 PEN-F. After OM System split from the Olympus/JIP holding group, the brand blended the series’ retro styling with modern durability and computational tools, positioning the new PEN as an everyday-carry option for street photographers.
Key Features & Specifications
- 20.4-MP Micro Four Thirds sensor, 2.36-million-dot EVF
- 1-million-dot fully articulating LCD
- 5.5-stop IBIS; IPX1 splash-proof rating (rain-resistant)
- 121-point AF with pet and human eye detection (still-only)
- 8-bit 4K video, 30 fps electronic shutter, 6 fps mechanical burst
- Customizable color and monochrome recipes via dedicated dial
- Live ND mode (four-stop), high-res and focus-stacking modes
- BLS-7 battery (~410 shots)
- Weight: 393 g (including battery) per Digital Camera World; 500 g reported by PetaPixel for the body alone
- Dimensions: 43.4 mm depth; available in black or silver
Official Statements & Responses
Digital Camera World notes the rarity of combining IBIS and weather-sealing at this price, calling the PEN the first in the series with an official weather-sealing rating.
On-the-Ground Reports
A PetaPixel reviewer field-tested the PEN across Japan, citing its ease of carry, stylish appearance, and reliable performance in humid summer conditions. The reviewer praised the quiet shutter, flexible color-mode dial, and long battery life, while noting a shallow grip and a lower-than-ideal AF/ON button placement.
Comparison with Sibling and Competitors
Compared with the OM-5 Mark II, the PEN shares the same sensor and processor but has a smaller grip, lower IP rating (IPX1 vs. IP53), and 5.5-stop IBIS versus the OM-5’s 7.5-stop system. The OM-5 offers faster mechanical burst speeds (10 fps vs. 6 fps). Among similarly priced rivals, the Nikon Z50 II provides weather-sealing but lacks IBIS; Canon’s EOS R7 and Sony’s A6600 include both features but start at $1,499 and $1,399 respectively. Panasonic’s Lumix G97 offers comparable stabilization and splash protection at about $850 when bundled with a lens.
Why It Matters
By delivering weather-sealing and IBIS at a sub-$1,000 price, OM System expands the appeal of Micro Four Thirds to users who value durability and portability without sacrificing image quality.
Conflicting Reports & Gaps
PetaPixel lists the body weight at 500 g, while Digital Camera World reports 393 g including the battery. No source provides a dust-resistance rating beyond the IPX1 splash-proof claim, leaving particulate protection unclear.
What’s Next
Shipping is expected in late October for the United States and in late September to early October for Europe. OM System also announced a kit lens, the M.Zuiko Digital 14-42mm f/3.5-5.6 III, to accompany the new PEN body.
