OM System PEN Review: A $1,000 Camera That's Easier to Love Than to Justify
PhotographyThe OM System PEN is a camera that looks like it should be expensive, handles like it’s thoughtfully designed, and under the hood runs the same technology you could have bought in a previous PEN model. Petapixel calls it “too familiar but oh-so-pretty” — which is either a reason to buy or a reason not to, depending on why you’re looking.
What It Is
The PEN sits at the compact end of OM System’s mirrorless lineup. At 500g and $1,000, it occupies the space between a capable travel camera and a stylish everyday carry — smaller and lighter than the OM-5 II, with a weather-sealed body that’s usable in rain.
Core specs:
- 20MP Micro Four Thirds sensor
- 2.36-million-dot EVF
- 5.5 stops in-body image stabilization
- 8 fps burst rate
- New BLS-7 battery format with notably better life than BLS-50
- Weather sealing, ~500g body
What Works
IBIS is genuinely useful. 5.5 stops of stabilization on a compact body makes the PEN competitive in low-light handheld situations that would challenge a camera without IBIS. This is the feature that sets MFT apart from APS-C and full-frame compacts in the same price range.
Battery life. The new BLS-7 battery format delivers a meaningful improvement over its predecessor. For a travel camera, this matters more than it might appear on a spec sheet — one fewer battery to pack, fewer midday recharges.
Computational features. Live ND, High-Resolution mode, and quiet shutter operation are all present. For a street photographer, the silent electronic shutter alone is worth something. Live ND is a genuinely useful tool that remains uncommon outside OM System’s lineup.
Autofocus. Human and pet subject detection works well, though the number of detectable subject categories is more limited than competitors at this price point.
What Doesn’t
The sensor is not new. The review is direct: “essentially the same technology we have seen many times before.” At $1,000, a 20MP MFT sensor with 8fps burst is not a specification that commands attention in 2026. The imaging performance is competent but not a reason to choose the PEN over alternatives.
Video is 8-bit. The PEN shoots video, but at 8-bit quality that Petapixel describes as “a little soft.” For photographers who expect the hybrid capability that most MFT cameras have delivered for years, the video output is a limitation.
Grip and ergonomics. The shallow grip requires a pinching hold for security, which is a usability compromise that the styling necessitates. The AF/ON button placement is awkward in practice.
Telephoto options are limited. The OM-5 II is the better choice if telephoto reach matters — the PEN’s small body and balanced MFT glass selection make it more suitable for wide and normal focal lengths.

The So What
The OM System PEN earns its 7.5/10 for doing what it promises: a compact, stylish, weather-sealed MFT body with good IBIS, good battery, and useful computational features, for $1,000. What it doesn’t offer is a reason to upgrade if you already own a recent PEN or OM-1 series camera. The audience that benefits most is a photographer buying their first serious compact mirrorless — someone who wants a real EVF, real weather sealing, and real stabilization in a body that doesn’t look like photo gear. For that buyer, the PEN is a reasonable starting point. For anyone expecting meaningful technical advancement from the PEN generation to this one, the review’s conclusion stands: too familiar.
