Ricoh GR III Accessories

The Ricoh GR III is a pretty self-contained little camera. Except for a memory card, there’s really not much else that you actually need to get before you head out shooting.¹

There are some accessories that are a higher priority than others. A spare battery, for example, comes in very handy.

Whether you’re looking to kit out your GR III or replace a part, here are the model numbers of some of the core accessories and replacement parts that are compatible with the Ricoh GR III.

I’ve been shooting with the Ricoh GR III since it was released in 2018. You can see some of the photos I’ve taken with it in these posts:

– Ricoh GR III Sample Images (a general collection of photos taken under various conditions)
– Ricoh GR III High ISO Sample Images (focusing on photos taken at high ISOs in low lighting)
– Ricoh GR III ISO Range Sample Images (sequence of images taken throughout the ISO range for comparing image quality at different ISOs)

SD card for the Ricoh GR III

The GR III doesn’t come with a memory card as standard, so you’ll most likely have to pick one up separately. Ricoh doesn’t make their own memory cards, and there’s no specific officially recommended SD card, but I’ve put together a detailed post on SD card recommendations for the GR III separately.

The short version is that the GR III takes SDXC and SDHC cards and has a UHS-I interface. And it doesn’t need the latest and greatest super-fast SD card.

You can find my GR III SD card recommendations here.

Here are the model numbers of some of the core accessories and replacement parts for the Ricoh GR III.

Lens ring cap for the Ricoh GR III

• Ring Cap: GN-1

The lens ring cap is the small plastic ring that attaches around the lens port. To the extent it’s a functional part of the camera, it’s mostly there to protect against grit getting into the attachment thread around the lens port. But it’s also largely decorative. Chances are, it’s fallen off. While you do have to remove it to attach the lens adapter for using filters or the wide-angle conversion lens, it’s a poor design that tends to fall off and get lost far too often. I’ve lost a couple of them now.

The camera will work just fine without it. But that will leave some contacts exposed around the lens barrel, which isn’t ideal.

The official replacement part is overpriced, but if you want to get the genuine replacement part, it’s model GN-1. But you can also pick up much less expensive aftermarket versions. They’re also available in different colors, so you can bling up your camera with a personal touch — or make it look like the Street Edition.

USB cable

The GR III has a USB Type-C connector port. When you get a cable, you can get them with another USB Type-C connector on the other end or a more traditional USB Type-A connector. Which you choose depends entirely on what you’re plugging into. For example, some newer laptops only have USB-C, while most other computers have USB-A.

Not all USB-C cables support data transfer, though. That’s often something you’ll run into with USB-C cables designed for fast charging. So it’s worth checking the product description and specs first. 

Ricoh GR III battery & charger

• Battery: DB-110

The Ricoh GR III takes battery model DB-110. It’s a rechargeable lithium-ion battery rated at 3.6V 1350mAh 4.9Wh.

There are some other cameras that also use the same battery — notably, some Olympus cameras (the Olympus model number for the same battery is LI-90B). So they’re quite widely available. You can get the official Ricoh version. There are also aftermarket versions that can be much better value but work just as well.

• Charger: BJ-11

You can charge the battery in the camera (using a USB-C cable). There are also external battery chargers available. They’re especially useful if you’re using spare batteries, so you can charge and shoot simultaneously.

• AC Adapter: K-AC166

This is used to power the camera for longer shoots, such as time-lapse, or if you happen to be using the camera for live streaming as a webcam. It connects via the camera’s USB-C port.

Ricoh GR III wide-angle conversion lens

• Wide-Angle Lens: GW-4
• Lens Adapter: GA-1

Ricoh has produced a wide-angle conversion lens that takes the standard 28mm view down to a 21mm (in 35mm equivalent). While it does add some extra bulk to an otherwise small camera, it works well and adds a more dramatic, wider view. I have an in-depth review of it separately.

Something to be aware of, though, is that you will also need to pick up the GA-1 lens adapter separately. For reasons I really don’t understand, the wide-angle conversion lens doesn’t come with the adapter, and both are required to make it work. So make sure you pick up one of those at the same time.

Remote shutter releases

• Wired Shutter Release: CA-3

This is the official Ricoh remote shutter. It connects to the camera via a USB cable, and it’s a simple shutter release (i.e., there’s no timer or intervalometer).

You can also find aftermarket shutter releases for the GR III.

External viewfinders

• Standard External Viewfinder: GV-1
• Mini External Viewfinder: GB-2

The Ricoh GR III doesn’t have a built-in viewfinder. But they make two versions of an external viewfinder that slides into the camera’s hot shoe. It covers both the standard 28mm view as well as the 21mm view if you’re using the wide-angle conversion lens. There’s also a mini viewfinder; that model seems to be hard to find.

Screen protector

The back screen of the GR III is quite exposed, and if you lie the camera on its back, the screen comes in contact with the surface. Even if you’re putting the camera in your pocket, there’s a risk of keys or coins scratching the screen.

There’s no official screen protector, but there are good aftermarket versions. The one I use is this one. It’s essentially a consumable that protects the screen. If you scratch the protector, you can quickly and easily replace it with another from the pack.

Ricoh GR III case

• Soft Case: GC-11 (replaces the GC-9)

You can, of course, use the GR III with just about any camera case or bag. But Ricoh does make a dedicated soft case that fits snugly around the camera and offers some protection even if you’re toting the camera around in your pocket. I’ve been using one for a couple of years, and it’s held up very well, and it keeps my camera safer from bumps and scratches.

(I’ve been using the older version, the GC-9. It has since been replaced with the GC-11, which looks to be basically identical but might have some minor alterations for the newer GR IIIx.)

• Neck Strap: GS-3

Again, there’s no particular reason you have to use the official GR neck strap, but there is one. The main part is leather, and it even has a discreet, embossed “GR”.

If you do use a different strap, be aware that the strap loops on the camera are very small and won’t take thicker (i.e., stronger) attachment loops. So you might need to use some D-rings as well.

• Hand Strap: GS-2

There’s even an official “GR” leather hand strap! But, again, aside from the branding, there’s no special reason to use the official strap. If you do use a different one, you might need D-rings if the thread doesn’t go through the camera’s small attachment loops.

External flash

Unlike some of its predecessors, the GR III doesn’t have a built-in flash. It supports the Pentax P-TTL flash protocol.

Pentax External Flashes:

• AF540GZ II
• AF360FGZ II
• AF201FG

Ricoh GR III manual

You can find it here. 

Something to be aware of is that if you do a web search for the manual, you’ll often end up at the manual for the Ricoh Digital III manual, which is a different, and older, camera. 

Notes & References:

1. The GR III does have a small internal memory, so as a technical matter, you can shoot without a memory card. But the memory storage is not very large and won’t get you far. It’s more of a safety net than a viable alternative to using an SD card. [↩︎]
