Ricoh Compact Flash GF-2 – USB-C charged flash unit for Ricoh GR IV

The essentials

The Ricoh Compact Flash GF-2 is a dedicated compact flash designed to work with the Ricoh GR IV. In plain terms, it’s there for one job: helping you add light when the scene is too dim, without turning your setup into a big camera-and-tripod production.

It’s not a “grab-and-go” flash in every sense—because it relies on the battery being rechargeable and not user-replaceable—but for everyday shooting it can be a handy way to extend what your GR IV can do. If you regularly shoot indoors, evenings, or in backlit situations, having a dedicated flash unit can make a noticeable difference compared with relying purely on ambient light.

What to expect in real use

On paper, the GF-2 is built around a built-in rechargeable lithium-ion battery. That means there’s no swapping batteries in the field. Instead, you charge it, and then use it until it needs power again.

Ricoh also quotes an approximate charge cycle: around 270 flashes when fully charged. That’s a useful planning number when you’re thinking about trips, events, or a busy day of photos. For example, if you’re photographing people at a café and taking frequent quick shots, you’ll get multiple bursts from a single charge, but it won’t last for endless firing.

The charging method is USB Type-C, and the charging time is quoted at approximately 2 hours. That’s convenient if you already use USB-C accessories in your kit (power bank, laptop charger, or similar). It’s also one of those details that can quietly decide whether you like a flash or hate living with it.

Key features that matter (not just the spec sheet)

The GF-2 is compact in physical terms, which is the point of a “compact flash” style accessory. Its stated dimensions are 51 x 31.4 x 17mm and weight is 19g—so it’s the sort of extra that doesn’t feel like a heavy appendage.

Another practical factor is the guide number figure provided: 3 (ISO100m). That’s quite modest, so it reads as a flash designed for close-to-mid range situations rather than overpowering bright daylight. If you’re aiming to freeze fast action far away, it may feel limiting. But if your goal is to add fill light for nearby subjects—portraits, street scenes, or small indoor moments—it’s the kind of output you can realistically build into your everyday shooting.

Also, keep in mind that the battery is not replaceable. For some buyers, that’s fine. For others, it’s a deal-breaker because it changes how the flash ages over years of use.

Where it shines, and where it may not

If you want a light, compact way to improve results with low light on the Ricoh GR IV, the GF-2 makes sense. It suits photographers who want to stay close to the small-camera philosophy: fewer accessories, simpler carry, and a flash that’s there when you need a bit more brightness.

It’s also a good match if your shooting involves short bursts—think quick portraits, street scenes at night, or general indoor moments where you’re not trying to light a whole room from across it.

However, it may not suit you if you need long endurance between charges or if you strongly prefer replaceable batteries for travel-heavy shooting. And with a guide number of 3, it’s unlikely to be the choice if you expect it to overpower daylight or reach far subjects.

Care and buying check list

Before buying, it’s worth sanity-checking a few things based on the information available here:

• Compatibility: the GF-2 is listed for use with Ricoh GR IV—if you don’t have that camera, you’ll want to double-check fit before ordering.
• Charging habits: USB-C charging and around 2 hours recharge time are convenient, but you should be comfortable charging it rather than swapping batteries.
• Expected firing volume: the quoted “approx. 270 flashes” is a guide for planning, not a promise that every shooting pattern will match.

Included in the pack

Not specified in the details provided. If you care about what’s in the box (cable, documentation, mount details), it’s best to check the listing contents before you commit.

Is it worth it?

Worth considering if you own the Ricoh GR IV and want a compact flash add-on for close or near-subject low-light shots, with USB-C charging and a quoted recharge window of about 2 hours. It’s a sensible purchase for everyday shooting where extra light helps, without adding much bulk.

You may want to skip it if you’re expecting high-power flash performance (the guide number is 3 at ISO100m, so range is limited) or if you dislike the idea of a built-in, non-replaceable battery—because that changes how the flash will be maintained over time.

Quick FAQ

Can you replace the battery?

No—the rechargeable lithium-ion battery is built in and not replaceable.

About how many flashes can you expect?

Ricoh quotes around 270 flashes when fully charged, which is best treated as a planning estimate.

What size and weight is it?

It’s listed at 51 x 31.4 x 17mm and 19g, so it’s designed to stay lightweight in your kit.
