Dust on Sensor
Dust particles enter the camera, deposit along the image path and become visible as black points / smudges on the photograph. With higher f-stops they stand out more clearly.
Who is reporting this problem?
The search for “Dust” on DPreview.com Ricoh Talk Forum brings up 102 threads.
And yes, the GR III is affected too.

Howto check for dust spots
To see the dust spots clearly we need to make a photograph of an evenly lit, uniform surface.
- Focus on a white surface or manual at the blue sky @infinity.
- Set the camera to Av-mode and increase the f-stop to f/11 or f/16. The higher the f-stop number the clearer dust particles become visible on the photo.
- To minimize high image noise interferance try shooting with low ISO 100-400. Less is better.
- If shooting handheld try to capture a sharp shot with a shutter time of at least 1/125th or faster. Use a tripod or put the camera on a flat surface.
- Make the photo, review the image on a bigger screen and note the location(s), lenght(s) and definitions of the dust spot(s).
Why does it happen?
There are two possible ways for dust to enter and deposit along the image path.
1 – Trough gaps in between the lens housing
The retractable GR & GR II Lens Unit consists of the housing barrels and the lens module. The unit is screwed onto a rectangle plastic plate with a blue glass in the middle, called “Hot Mirror“. It reflects the infrared light and also acts as physical barrier against particles depositing on the sensor behind it. With the lens breathing air while extracting and retracting, dust particles can enter the housing trough the front and side gaps in between the rotating barrels. Ricoh engineers tried to seal both pathways using a stripes of thin foam like material. The material thicknes and sealing quality degrades with usage. It is suspectible to tear apart and flake into smaller pieces which can enter the lens too. Particles traveling trough the lens will most likely deposit on the Hot Mirror and not on the sensor.
2 – Trough gaps in between the camera controlls and inside the body
The magnesium and plastic parts of the GR camera body include three openings for particels to enter the body. The first around the ADJ. Lever/Button. The second around the Front Wheel. The third inside the Battery Compartment. Dust and particulary the photographers own dead finger skin can enter on each side of the controls. When inserting the battery dust particles can be pushed trough the cutout holes in the battery compartement into the body.
To protect the Ricoh GR and GR II sensor the engineers decided to place a rectangular shaped Rubber Seal on top of the sensor plate. Once the sensor module is screwed together with the beforementioned lens module, the rubber seal squeezes together, ideally forming a protective dust barrier. However the rubber does not necessarily compress in a uniform way (lower left photo below). This is potentially the achilles heel for particles to slip under.
The GR III lens module is different
The description about rubber seal does not apply to the GR III model in the same way. As showed in the the YT-video Meeting Ricoh Imaging Japan! (GRIII & Showroom) @15:15min. the hot mirror seems to be screwed directly on top of the sensor, making a possible seal more tight or even unnecessary. However the question remains if there is a physical barrierer in between the hot mirror and the lens module?
Howto prevent dust from entering
- Seal the lens against particles that might enter the body trough the gap in between the moving lens barrel.
- For the GR & GR II mount the GH-3 Lens Adapter (affiliate Link) + a 49mm clear filter.
- For the GR III mount the GA-1 Lens Adapter (affiliate Link)+ a 49mm clear filter .
- Turn the camera off in between shots (startup, lens extrusion time is only 0,8-0,6 seconds)
- Store the camera in a lint free (neopren) camera bag. Not your jeans pocket!
Howto remove dust spots
- Software removal
- Eliminate visible particles on the image by using the clone tool in Photoshop or Lightroom
- Shaking the Sensor/Camera:
- Activate the built in shake / dust removal feature (GR III only)
- Use an ultrasonic toothbrush to vibrate the body and the particles off the sensor (see video below)

Closed Shutter after Power On
The Ricoh GR & GR II shutter remains closed after Power On and the display remains black.
Who is reporting this problem?
- Ricoh GR Closed Shutter Problem
- Lens/shutter Closed on Start-up
- My GR died after 11k shots. Is this the average lifespan of a GR?
- GR/GR II life expectancy …?
- Ricoh GR aperture blades won’t open at start up
- GR closed lens on startup – dust?
- GR – shutter remains closed on start-up
Why does it happen?
Possible reasons
- The “Shutter Flex Cable” connecting the camera controlls and the lens module starts to break. We collected comments about others reporting the problem.
- Moisture got inside and caused the delicate Leaf Shutter Blades to become sticky.
In the Ricoh GR (II) disassembly video below I discuss the possible “Shutter Flex Cable” issue.
Howto avoid it
- <irony> shoot less </irony>
- Do not expose the camera, especially the lens barrel to wet conditions.
Howto fix it
Temporarily
The closed shutter will open after making one “dark frame” exposure.
- Shoot in TAv or manual mode using a fast shutter speed and open aperture. (In any other shooting mode the camera will need longer time to open because it will expose for the black shutter.)
Long term
- Replace the “Shutter Flex Cable“
- Contact and send the camera to an authorized Ricoh camera repair service in your region.
Stuck Out & Locked Lens
After power off the lens will not retract into the body and remains in the the extended power on position. Pushing and forcing the lens back inside the body is not possible.

Why does it happen?
Possible reasons
- The camera was dropped and the lens barrels are missaligned.
- The camera encountered and internal error. It is programmed to extended the lens to a fail safe point.
Howto avoid it
- Do not drop your GR on the ground ^_^

Skipping ISO Values when turning Circle Dial (GR III)
Ricoh GR III users report that turning the rear circle dial (adjusting ISO) leads to unexpected outcomes. ISO values randomly jump up or down. For example, instead of going down from ISO 800 to 400 the ISO changes to 1000.
Who is reporting this problem?
“ISO dial on my GRiii is on the fritz!”
Why does it happen?
Most likely grease, dead skin or other small particles have accumulated under the round function dial. The continouus electronic contact is disturbed, leading to nonlinear value changes.
Howto avoid it
Wash your hand and clean wipe the camera back once in a while (:
How to fix it
- Some people report that quickly spinning the circle dial resolves the problem temporarily.
- A longer lasting solution would be to remove any accumulated particles underneath the circle dial by using compressed air (rocket blower)
- DYI disassembly and replacement of the dial https://www.dpreview.com/forums/thread/4600195
Sticky Shutter Button
One side of the rectangular shutter button gets stuck in the button corner.
Who is reporting this problem?
A discussion about this topic is available on the dpreview.com forum
Why does it happen?
Fingertip grease and dust tend to accumulate under the button, making it less responsive. The shape invites a rocker-like motion and allows possible stickiness.
Howto avoid it
Use gloves 🙂
How to fix it
Pressing the button in its center helps to release it from the blocked position. A possible cleaning method would be to use a syringe and inject small amounts of electrical contact cleaner under the button, while the camera is upside down.
Grip Rubber Stretching
The Problem
The front and back rubber grip starts to stretch, moves and finally peel off.
Why does it happen?
Touching and pressing against the rubber heats up the glue below. Over time the glue becomes less sticky and allows the rubber to stretch outside the rims.
How does it affect the photographic process?
Touching the grip does not feel stiff and secure anymore.
Howto avoid it
I think the problem can only be avoided by not holding and using the camera for extended periods of time, especially in a warm and humid environment.
Howto fix it
- Cut away the overstretched and excessive rubber parts.
- The remaining rubber should fit nicely inside the body rim again.
- Remove the old, yellow looking glue.
- Use superglue to attach to remaining rubber the body.
- Be very careful not to spill the glue over the body or controls. It is very reactive and fast drying!
Where is more information about the issue?
- User reporting same issues with the older Ricoh GR IV model on Dpreview Forums
- Longtime Ricoh GR Review report on compactshooter.com
I read in several fora that The griii has a Huge heat problem. Is it Common to this model or is it just happensonly in some faulty batches?
Hi Mauro, from what I read on several forums, (I read Dpreview most frequently) the heat issue affect every GR III until now. It appears to be more noticeable after longer power-on times. If you turn the camera off and on the heat will not built up as fast. Check this infrared heat camera comparison (including GR III) for example https://www.dpreview.com/forums/post/62558531
Well, seems that now I reached 3 of 4 issues you listed above. I really love the camera (maybe because was my first) now thinking about what could be the next and of course, one more durable. Thanks for putting together all this known issues
Sorry to hear Daniel. At least you maxed it out! Whats the next camera? This seems to be always a good discussion starter 🙂 How about a camera with a non-retractable lens design? You can check out https://streetphototip.com/library/52-pancake-lens-comparison-list-street-travel-photography/ to get a small pancake lens to go with it. Good luck and let us know what you got instead!
Thank you for this post – very helpful!
I have the stuck lens problem. I‘m curious if there’s a way to fix theses plastic gears that move the lens mechanism? For example to clean it from dirt and to put a little oil to it?
Have you tried this?
I‘m asking before dismantling the camera in vain..
thanks in advance for your opinion!
Best,
Artem
Hallo Artem
In order to get to the white motor gears you will have to unscrew pretty much all parts inside the body. I did this procedure one a one way trip and did not plan to put it back together. I am not sure if anything can get in between the white gears since they are normally covered by a black plastic plate. In the video I removed the plate to show the moving gears. Also putting oil on them would not be recommendable, it could easily spill around.
Best of luck fixing your gear!
Michael
Thanks for the insights. I love the images these cameras can produce, but I may now skip the grIII to replace my prehistoric Fuji s5..Fuji I wish I knew how to quit you.
Sincerely,
Don Pancake
Hello Michael, and thanks very much for the clear and well-organized post.
FWIW, on the DPReview site I posted about an examination of the GR lens unit I did, with respect to the stuck lens/dust-sealing problem. I have since bought a GR II, plus the adapter and clear filter, in light of what I found in this examination of my GR. What looks like a flimsy lens casing gasket, plus poor sealing against dust, seem to add up to a poor design with respect to durability in less than optimal conditions. The adapter and filter are a must if you live or take photos in dusty surroundings.
https://www.dpreview.com/forums/thread/4482509
I concur and do the same. Protecting the lens using the lens adapter+filter has priority over size and portability. I noticed and commented on your post on dp too! My broken GR (stuck lens) waits to be inspected it in more detail. I will record and discuss my findings in a video.
How repair Closed Shutter after Power On and Stuck Out & Locked Lens. The cause of the malfunction is a break in the Lens Shutter Flex Cable at the bend (half-width crack). I installed a Lens Shutter Flex Cable For RICOH GR GR2 with Aliexpress and now mine RICOH GR2 works.
Thanks Vadim for follwing up and pointing out a possible cable failure. In fact I broke mine while dissassembling my Gr. This would be a good time to order a new one and install it. The needed soldering tip seems to be a precise one. I will be happy to learn if this 2,99 $ spare part is able to fix the shutter closed issue.
Hello Michael,
The other day my GR II took an unfortunate tumble. Thankfully the unit is still functioning however, the cover that closes over the lens, refuses to fully close on power off. This means that when the unit is off, the lens is vulnerable to dust particles. I have already ordered a cap on Amazon for the time being. Is there any way to fix this issue?
Hello Andrew
From my experience with the lens unit dissasembly it is possible to make it work again. However I only managed to trigger the full closure after removing and reinserting the lens unit out its surrounding barrel enclosure. To get there is a long way with many unscrewing parts! I published a GR dissasembly video to show the way. Good choice to order a cap. As far as I know there exists a auto-open and close cap too!
Hello Andrew, I had the same problem after dropping mine…check the ring with the writing on it is not raised slightly – if it is press it back down. I know of two other cases where this had happened after dropping and that was a solution!
Hi Michael, thank you in advance for the help.
My problem is that the flash on my Ricoh GRII has just stopped working. I am making sure that auto bracket, continuous shooting etc is turned off. I tried all modes but it wont come on. What could be the problem?
Rick
Hallo Rick
if not related to settings (tried factory resetting the camera?) it could be a hardware problem. A loose solder cable contact from a drop, a defect photoflash capacitor (the build in flash-battery) or even defect flash bulb.
As you show it very clearly, the Ricoh GR (both analogue and digital) is very prone to many problems. I know what I am talking about. I have had several GR’s and encountered all those issues. This is very sad for such a fine, but rather expensive camera. It simply should be built more solidly.
