Best Flash for Ricoh GR III: Detailed Reviews
Godox iT20 R (for Ricoh) View on Amazon
The recently announced Godox iT20 R for Ricoh is poised to be an absolute game-changer for GR III users. At a mere 45g, it promises to be ultra-light and pocket-sized, maintaining the GR III’s core strength of portability. What truly excites me, and should excite you, is its full TTL (Through-The-Lens) compatibility, meaning the camera handles flash exposure automatically β a luxury often missing in super-compact options. It’s designed specifically for Ricoh GR cameras and boasts over 700 full-power flashes on a single charge, which is impressive for such a small unit. While it’s very new on the market (announced December 2025), its magnetic accessories also hint at greater versatility. The only minor drawback is its newness, which means extensive user reviews are still emerging, but the specifications are incredibly promising for any GR III shooter seeking convenience and power.

Godox iM30 Mini Flash View on Amazon
For those prioritizing value without sacrificing too much control, the Godox iM30 Mini Flash is a fantastic choice. It’s lauded for its retro design and pocketable form factor, making it a natural fit for the discreet Ricoh GR III. While it operates in manual mode, which requires a bit more thought, its top-mounted power dial offers quick and intuitive adjustments across several power levels (up to 7 levels, typically). This means you can fine-tune your light output on the fly, a feature I truly appreciate for dynamic street shooting. It weighs just 78g, comparable to a lipstick, enhancing the GR III’s portability. It runs on two easily replaceable AAA batteries, which is a common and convenient power source. With a recent firmware update for the GR III, this flash can even work in the camera’s GF-2 flash mode for automatic metering on its lowest setting, adding a layer of convenience despite being manual.

REFLX Lab Mini Flash View on Amazon
If your primary goal is to add a tiny, almost imperceptible kiss of light without adding any bulk, the REFLX Lab Mini Flash is your ultimate budget pick. It’s quite literally about the size of an SD card, making it arguably the smallest flash available for the Ricoh GR III. This flash is pure minimalism; it has zero settings, offering a fixed, low output. This means you’ll rely entirely on your GR III’s manual exposure settings to achieve the desired effect, but with the GR III’s excellent manual controls, it’s a fun challenge. It features a built-in battery that charges via USB-C and offers around 200 flashes per charge with a quick 1.5-second recycle time. It’s perfect for intimate indoor shots or adding a subtle pop in dim street scenes. Its honest limitation is that its fixed output can be overblown if not carefully managed, and its tiny size means it can be easily knocked off the hot shoe. But for sheer discreetness and affordability, itβs hard to beat.

Pentax AF201FG Auto Flash View on Amazon
For those who prioritize automatic, reliable flash exposure and don’t mind a slightly larger footprint, the Pentax AF201FG is my premium recommendation. It’s one of the “official” Ricoh-recommended flashes, offering full P-TTL (Pentax Through-The-Lens) functionality with the GR III. This means the camera intelligently controls the flash output, making it incredibly easy to achieve well-exposed images, especially in dynamic lighting situations. With a guide number of 20 (at ISO 100m), it provides ample power for most scenarios, and critically, it features a vertical bounce head. This allows you to soften and diffuse the light by bouncing it off ceilings, creating much more flattering and natural-looking illumination than direct flash. While it’s certainly larger than the tiny manual flashes, it’s still relatively compact for a P-TTL unit, weighing about 141g without batteries, and runs on two AAA batteries. For events, portraits, or any situation where consistent and automatic flash is paramount, this is a fantastic, dependable choice.

LightPix Labs FlashQ Q20 II View on Amazon
The LightPix Labs FlashQ Q20 II is an “Also Great” pick because it offers something unique for the GR III user: wireless capabilities in a relatively compact package. This system includes a flash unit with a built-in receiver and a small transmitter that mounts on your GR III’s hot shoe. This allows for incredibly creative off-camera flash setups, enabling you to sculpt light in ways an on-camera flash simply can’t. The flash head itself can tilt, and it comes with color gels to further expand your creative options. It’s a manual-only flash, so you’ll be setting power levels directly on the unit or via the transmitter. While some users find it a bit bulkier than other mini flashes when mounted directly on the camera, its ability to detach and fire remotely truly unlocks new photographic possibilities. It’s powered by a rechargeable lithium-ion battery via USB, offering convenience for on-the-go charging. For those ready to experiment with more advanced lighting, the FlashQ Q20 II is an excellent, versatile tool.

Frequently Asked Questions
Does the Ricoh GR III have a built-in flash?
Unlike some earlier GR models, the Ricoh GR III does not feature a built-in flash. This design choice contributes to its incredibly compact size and minimalist aesthetic, but it necessitates an external flash for situations requiring additional light. This is why selecting the right external unit is so important to complement its capabilities.
What does P-TTL mean for the GR III?
P-TTL stands for Pentax Through-The-Lens. It’s an automatic flash exposure system that the Ricoh GR III is compatible with, thanks to Ricoh also owning Pentax. When using a P-TTL compatible flash, the camera’s metering system communicates with the flash to automatically determine the correct flash output for a well-exposed image, taking the guesswork out of flash photography.
Can I use any flash with the Ricoh GR III?
You can physically mount almost any flash with a standard single-contact hot shoe onto the Ricoh GR III, and it will typically fire. However, only flashes compatible with the Pentax P-TTL system (like Pentax-branded flashes or specific Godox/Metz models designed for Pentax) will offer automatic TTL exposure. Other flashes will operate in manual mode, requiring you to set the power output yourself.
How do I use manual flashes with the GR III?
To use a manual flash with your GR III, you’ll generally set your camera to manual exposure mode. You’ll then adjust the flash’s power output (e.g., 1/1, 1/4, 1/16 power) directly on the flash unit until you achieve the desired exposure. Some newer manual flashes, like the Godox iM20/iM30, can interact with the GR III’s GF-2 flash mode after a firmware update, allowing the camera to meter for the flash, though usually only on the lowest flash setting.
Why choose a small flash for the GR III?
The Ricoh GR III is renowned for its discreet, go-anywhere nature. A small flash maintains this core appeal, keeping your setup lightweight and inconspicuous. Large flashes can make the camera feel unbalanced and less portable, defeating one of the main reasons to choose the GR III. Tiny flashes are ideal for subtle fill light in bright conditions or adding a discreet pop in low light without drawing attention.
Final Verdict
For Ricoh GR III owners, the choice of flash profoundly impacts the camera’s portability and ease of use. If you crave the ultimate convenience of automatic exposure in a truly pocketable form, the newly released **Godox iT20 R (for Ricoh)** is a standout, promising seamless TTL integration without compromising the GR III’s size. For those who prefer hands-on control and excellent value, the **Godox iM30 Mini Flash** offers adjustable manual power and fantastic portability.
