Best Settings for Ricoh GR IIIx: Autofocus, Snap, Video

Our pick: if you change only one line, raise the Minimum Shutter Speed to 1/125 sec. The 1/40 sec default is a stabilization number: the 3-axis Shake Reduction keeps your hands steady, but it does nothing for the person walking through the frame.

Face/Eye Detection is set to work only in Auto-area AF on purpose. The manual says it runs in Auto-area, Select and Pinpoint AF when set to On, which means it can pull focus to a face at the edge of the frame when you chose a zone for a reason.

GR IIIx autofocus settings: which AF mode to use

The GR IIIx uses hybrid AF, combining phase-detection on the sensor with contrast detection, according to Ricoh's spec sheet. The manual lists nine focus options. Here is how we would use them:

Focus mode	What it does	Use it for
Auto-area AF	Camera picks the point	Casual snaps, group shots
Zone Select AF	You place a 3x3 zone, camera picks inside it	Street, travel, most days
Select AF	One point you move	Portraits, deliberate framing
Pinpoint AF	Smaller area than Select AF	Details, focusing through gaps
Tracking AF	Follows the subject under a half-press	Kids, cyclists
Continuous AF	Refocuses while you half-press	Walking toward you
MF	Manual, with peaking	Macro, tripod work
Snap	Fixed distance	Fast street work, low light
∞	Fixed at infinity	Skylines, landscapes

Zone Select AF is our default. Ricoh added it in firmware 1.41, describing a freely movable 3x3 focus area with automatic positioning inside it. It fixes the weakness of Auto-area AF, which tends to pick the nearest object, without forcing you to place a single point precisely. If your menu does not show it, update the firmware; the current version is 1.60, released October 23, 2025.

Three more settings matter. AF.C Setting offers Focus-priority or FPS-priority for Continuous AF; keep Focus-priority unless you shoot bursts. Focus Peaking (Highlight Edge or Extract Edge) makes MF and macro usable on the rear screen. And for back-button focus, set Shutter Button Setting to AE Lock in the D2 menu, which the manual says stops autofocus on a half-press, then give AF to a Fn button.

Our GR III autofocus settings guide goes deeper into each mode. The menus are the same on both cameras, so it applies here too.

Snap focus at 40mm: distances and apertures

Snap mode fixes focus at a preset distance so the shutter fires instantly. The manual lists 1m, 1.5m, 2m, 2.5m, 5m and infinity, and Ricoh's firmware notes add 3.5m (version 1.10) and 0.3m with the aperture fixed at F16 (version 1.31).

Full Press Snap is the GR feature that matters most. With it on, a half-press runs your normal AF mode, while a fast full press shoots at the snap distance. The manual lists where it does not work: movie mode, macro mode, self-timer, and when Focus is already set to MF, Snap or infinity.

The catch at 40mm is depth of field. We calculated the sharp zone for the GR IIIx's 26.1mm lens using a standard 0.02mm circle of confusion for APS-C:

Snap distance	Aperture	Sharp from	Sharp to	Use it for
2m	f/5.6	about 1.5m	about 3m	Close street, markets, dusk
2m	f/8	about 1.4m	about 3.7m	Close street in daylight
2.5m	f/8	about 1.6m	about 6m	General street (our pick)
3.5m	f/8	about 1.9m	about 19m	Plazas, wide scenes
5m	f/8	about 2.3m	infinity	Architecture, city views

Our pick: 2.5m at f/8, which happens to be the camera's default distance. Keep f/8 in daylight; at f/5.6 the same distance only holds about 1.8m to 4.2m. GR III shooters used to "2m at f/5.6 covers everything" will find that is not true at 40mm. Our snap focus and zone focusing guide explains the technique; just use the distances in this table.

Put Snap Focus Distance on the ADJ lever (it is one of the options in ADJ Mode Setting) so you can change it without opening the menu.

Exposure and ISO

Ricoh lists ISO 100 to 102400, with Auto ISO lower limit, upper limit and minimum shutter speed all adjustable. The manual's defaults are a 100 floor, a 6400 ceiling and a 1/40 sec minimum. We keep the ceiling and change the speed:

Situation	Mode	ISO Auto Upper	Min. shutter
Daylight street	Av, f/8	6400	1/250 sec
Overcast, indoors	Av, f/5.6	6400	1/125 sec
Night streets	Av, f/2.8 to f/4	12800	1/60 sec
Still scenes at night	Av, f/2.8	6400	1/15 sec

Metering: Multi-segment by default, and Highlight-weighted when bright signs or windows are in the frame. Imaging Resource lists exposure compensation of ±5 EV in 1/3 EV steps. Use it at night: dial in -0.7 EV or so to keep dark streets dark, the way they looked.

If you shoot in P, the A2 menu has a Program Line setting (Normal, Max Aperture Priority, DOF Priority (Deep)). DOF Priority keeps apertures small, which suits snap shooting at 40mm.

Crop modes and custom buttons

The GR IIIx crops to 50mm or 71mm. The manual notes the cost: at 50mm, Large JPEGs are recorded at Medium size, and at 71mm, Large and Medium JPEGs become Small. Treat 50mm as a real second lens and 71mm as an occasional reach tool. Our crop mode guide covers when to crop in camera and when to crop later.

The Fn Button Setting list is long. These are the assignments we would make:

Control	Function
Fn button	Crop (Off / 50mm)
ADJ lever	Snap Focus Distance, ISO, Image Control, AE Metering
Movie/Wireless button (hold)	ND Filter, if your model has one
Touch AF (D2 menu)	Full Press Snap, so a tap shoots at the snap distance

Then save three complete setups to USER1, USER2 and USER3 on the mode dial: U1 for daylight color (the first table), U2 for night (f/2.8, Auto ISO to 12800, 1/60 sec, snap at 2m) and U3 for black and white. Our U1, U2, U3 guide walks through saving and renaming them.

GR IIIx video settings

Video is the GR IIIx's weakest area, but it is usable once set up correctly. Ricoh's spec sheet lists Full HD 1920x1080 at 60p, 30p or 24p in H.264 MOV, up to 25 minutes or 4GB per clip, with a built-in stereo microphone. There is no 4K.

Setting	Our value	Why
Framerate	24p (60p for slow motion)	24p gives the film cadence
Focus	AF, half-press before recording	Locks focus on your subject
Touch AF	On	Lets you refocus by tapping while recording
Movie SR	On	Steadies handheld clips
Sound Recording	Off, or On for ambient sound	Operation sounds are recorded too
Image Control	Same recipe as your stills	Matching look across stills and clips
White Balance	Fixed, not Auto	Stops color shifting mid-clip

Two details from the manual change how you shoot. Movies are always recorded in Program mode, whatever the mode dial says, so brightness is controlled only with exposure compensation. And the camera may stop recording if it gets too hot, so keep clips short in summer sun. For walking shots, set Focus to Snap at 2.5m and let the depth of field do the work. Our cinematic settings guide has looks that suit 24p.

Mistakes we see all the time

• Copying 28mm snap advice. 2m at f/5.6 is a narrow band at 40mm. Use 2.5m at f/8.
• Leaving the minimum shutter speed at 1/40 sec. Stabilization fixes your hands, not moving people.
• Running Face/Eye Detection in Zone Select AF. It overrides the zone you chose. Limit it to Auto-area AF.
• Expecting Full Press Snap in macro or self-timer. It switches off there, by design.
• Setting shutter speed for video. Movies run in Program mode. Use exposure compensation instead.
• Skipping firmware updates. Zone Select AF, Negative Film and the 3.5m snap distance all came in updates.

In short

The best Ricoh GR IIIx settings are Av at f/8, Zone Select AF with Full Press Snap at 2.5m, and Auto ISO capped at 6400 with a 1/125 sec minimum, saved to U1 with your favorite recipe. The 40mm lens is what changes things: use smaller apertures and longer snap distances than you would on a GR III. For the camera itself, read our Ricoh GR IIIx guide.

Every Ricoh Presets recipe runs unchanged on the GR IIIx. For an everyday look that suits 40mm people pictures, get the Natural Analog recipe ($3.99), or the Street Essentials bundle ($8.99) for three street looks, including Classic Chrome.
