Best Microphone for OM SYSTEM PEN
The OM SYSTEM PEN has a 3.5 mm TRS microphone jack and no headphone jack. The body is 393 g. A full-size video mic turns that rangefinder into a short boom pole. The on-camera mic that stays on that scale is the RØDE VideoMicro II.

How We Picked
Three official facts. This is a 393 g PEN with a 3.5 mm jack, not an A7S III XLR cage and not a Sony Multi Interface shoe.
- Weigh the jack, then the body. B&H PEN specs: one 3.5 mm TRS stereo microphone input; Other I/O: No — no headphone jack. USB-C, Micro-HDMI, hot shoe, 393 g with battery, 125.8 × 74.5 × 43.3 mm. Movie rows: UHD 4K 102–105 Mbps, C4K 237–240 Mbps, OM-Log400 8-bit, 16-bit 48 kHz or 24-bit 96 kHz PCM. OM calls out 4K, vertical video, and the 3.5 mm connector on the same feature list.
- Keep the mic inside the camera’s mass budget. RØDE VideoMicro II: 80 mm long, 39 g, supercardioid, annular line tube, HELIX isolation mount, no battery, 3.5 mm TRS-to-TRS and TRS-to-TRRS in the box. That is a shoe mic a 393 g rangefinder can forget. A long NTG on the same shoe is an A7S.
- Wireless is for voices, not for monitoring. DJI Mic Mini specs: transmitter about 10 g (26.55 × 26.06 × 15.96 mm); receiver about 17.8 g; official runtime measured with the receiver on a camera via the 3.5 mm TRS camera cable. Monitor interface output power is a dash — and the PEN has no headphone jack to fill that gap. Sony MI camera adapters stay on Sony bodies.
Detailed Reviews
RØDE VideoMicro II View on Amazon View on B&H
| SKU | VideoMicro II — RØDE |
|---|---|
| Size / weight | 80 mm long · 39 g |
| Pattern | Supercardioid · annular line tube |
| Mount | HELIX isolation mount · cable slots · shoe + boom thread |
| Power / cable | No battery · 3.5 mm TRS–TRS (camera) and TRS–TRRS (phone) |
| In the box | Foam + furry windshields, both cables |
Why it fits the PEN. Plug-in power from the 3.5 mm jack is the whole interface. 39 g on a 393 g body is a 10 percent add, not a new kit bag. HELIX is the isolation mount RØDE built for this capsule. The PEN still cannot monitor in a headphone — set level in the camera menu and treat the first clip as a meter. Pair it with a V30 card from Best Memory Card for OM SYSTEM PEN.

DJI Mic Mini View on Amazon View on B&H
| SKU | DJI Mic Mini (1 TX + 1 RX) — DJI specs |
|---|---|
| Transmitter | DMMT01 · 26.55 × 26.06 × 15.96 mm · ~10 g · ~11.5 h |
| Receiver | DMMR01 · 46.50 × 29.61 × 19.32 mm · ~17.8 g · ~10.5 h |
| Radio | 2.400–2.4835 GHz · Bluetooth 5.3 |
| Camera cable | Official runtime is measured on a 3.5 mm TRS camera cable |
| Monitor | DJI lists monitor output as “—”. PEN has no headphone jack. |
Why it is Value. A 10 g transmitter on a collar beats a long shotgun when the subject talks. The receiver stays on the PEN shoe and dumps analog into the same 3.5 mm jack. Skip the Sony MI camera adapter — that is a Sony. Skip expecting a headphone check. Set gain in the camera, then listen on a computer.

| SKU | VideoMicro — RØDE |
|---|---|

| Pattern | Cardioid condenser |
| Mount | Integrated Rycote Lyre |
| Power | No battery · camera plug-in power |
Why it is Budget. Same idea as VideoMicro II: short, plug-powered, PEN-scale. 42 g versus 39 g is not the story. The II adds HELIX, a supercardioid capsule, and both cables in the box. Take the original when it is the price on the table and the day is still a shoe mic, not a wireless kit.

If You Need Something Else
A long NTG, an XLR handle, or a Sony Multi Interface adapter is an A7S. The PEN is 3.5 mm TRS and 393 g.

| This jack | B&H: one 3.5 mm TRS mic input. Other I/O: none. |
|---|---|
| This body | 393 g · 43.3 mm deep · hot shoe, not an MI digital shoe |
| PEN job | Works only if you add a cage the camera was not designed around. |
Keep the long shotgun on Best Shotgun Microphone for Sony a7S III. On this PEN, VideoMicro II or Mic Mini is the scale match. A spare BLS-7 still matters more than a heavier mic — 4K and an EVF share one 410-shot cell.

Frequently Asked Questions
Why VideoMicro II is Overall instead of a full-size NTG
The PEN is 393 g with a 3.5 mm jack and no headphone. RØDE lists VideoMicro II at 80 mm and 39 g, plug-powered, with a TRS–TRS cable in the box. A long NTG is an a7S on a body that was designed to disappear in a jacket.
Whether the PEN can monitor headphones while recording
B&H lists one 3.5 mm TRS microphone input and no other I/O. There is no headphone jack. DJI’s Mic Mini spec also leaves monitor output blank. Set level in the camera and check the file later.
Why Mic Mini is Value instead of Overall
Mic Mini is the talking-head kit: 10 g on a collar, 17.8 g on the shoe, official 3.5 mm TRS camera cable. Overall is the always-on shoe mic that needs no pairing and no extra batteries. Different job.
Whether a Sony MI adapter helps
DJI’s own FAQ for the Mic Series camera adapter is a Sony Multi Interface shoe path. The PEN is a standard hot shoe plus analog 3.5 mm. Use the TRS camera cable.
What the PEN records once the mic is plugged in
B&H: 16-bit 48 kHz or 24-bit 96 kHz PCM in the MOV file, next to UHD 4K at 102–105 Mbps or C4K at 237–240 Mbps. A V30 UHS-I card covers that movie table. The mic does not change the card class.
Final Verdict
For the OM SYSTEM PEN, buy the RØDE VideoMicro II. Take DJI Mic Mini when the voice is off-camera. Take the original VideoMicro when II is the wrong price. Leave XLR and Sony MI adapters on full-frame video bodies. This jack is 3.5 mm TRS, and this body is 393 g.
