Camera remote release pinout list


Most DSLR and SLR cameras can be triggered remotely using a release cable. Unfortunately the connectors used for the external release have rather exotic shapes. Below you will find the pinouts for the common camera types. The standard solution consists of three wires: ground, focus and shutter. To focus the camera the focus wire has to be connected to ground. To release the camera both wires have to be connected to ground.


All Canon EOS cameras are equipped with a remote release connector. There are two types of plugs. Refer to this article for more details on the electrical data of the external trigger ports. Most types can be released by pulling down just the shutter wire.

2.5mm Jack Connector

Pinout wired remote control

This connector is used with:
EOS 350D, 400D, 450D, 500D, 550D, 600D, 650D, 700D, 750D, 760D,
EOS 60D, 70D, 80D,
EOS 1000D, 1100D, 1200D, 1300D.
The 60D is the first two digit camera using a jack plug. It's is a DIY friendly stereo (3 pole) 2.5 mm jack plug. It is not the standard plug used in mp3-players etc. which has a diameter of 3.5 mm! But don't worry, you can buy this smaller plug in a bigger electronics store. The 'official' remote controller with this plug sold by Canon is called RS-60 E3.

N3 Connector

Pinout Canon N3 connector

This connector is used with the EOS 10D, 20D, 30D, 40D, 50D, 5D, 5Dmk2, 5Dmk3, 5Dmk4, 5DS, 6D, 7D, 7Dmk2 and all types of the 1D. The only way to get the connector is canibalising a cheap remote control. The 'official' remote controller with this plug sold by Canon is called RS-60 N3.

Fuji (Fujifilm)

Fuji has currently three types of wired shutter release connectors.

2.5mm Jack Plug

Some of the Fujis have the standard 2.5mm jack socket to connect the microphone. This socket also serves as a shutter release socket. The wiring is compatible with Canon and Pentax (see above) and cheap remotes designed for these brands can be used. This DIY friendly connection exists in the models:
X-T1, X-T10, X-T20, X-E1, X-E2.

Fujifilm RR-80

Cameras specified to work with the Fuijfilm RR-80 remote control can be controlled using a miniUSB plug and some additional circuitry. The male miniUSB plug is offered by bigger electronic component vendors.
The images below show the wiring of an adapter cable to the standard jack plug as needed by the SmaTrig for example. the cable.

fuji rr-80 diy remote pinout
fuji rr-80 diy cable

This cable works with the models:
S205EXR, S200EXR, S100FS.

Fujifilm RR-80A

The RR-80A has a proprietary plug that will be hard to find. The only advantage compared to the RR-80 is the additional compatibility to the HS50EXR. Adapters from the RR-80 to the RR-80A plug exist and are probably the only way for DIYers to control for the HS50EXR. Compatible types:
S205EXR, S200EXR, S100FS.

Fujifilm RR-90

This is the successor of the RR-80 with the smaller microUSB plug. This plug is commonly used for charging smartphones. You can use a miniUSB-female to microUSB-male adapter to connect the older RR-80. Most probably the circuitry shown above will also work with a microUSB plug instead of the miniUSB. Compatible types:
FUJIFILM X-T1, X-T10, X-T20, X-E2, X-M1, X-A2, X-A1, X100T, X30, XQ2, XQ1, FinePix S1


Hasselblad uses the same 2.5mm stereo jack connector as Pentax and the smaller Canons. It fits the H, H1 H1D, H2, H2D, H3D.


With three different types, Nikon is the unbeaten leader in inventing remote release connectors.


nikon remote release connector pinout, d70, d80, mc-dc1

This type fits the D70s (not D70!) and D80.


nikon remote release connector pinout mc-dc2

This type fits the D90, D3100, D3200, D3300, D5000, D5100, D5200, D5300, D5500, D7000, D7100, D7200, D600, D610, D750 and DF. It was introduced to connect the GPS-receiver. The D90 was the first cam to appear with this new connector.

10-pin connector (MC-20, MC-22, MC-30, MC-36)

nikon 10 pin remote release connector pinout

This is the connector found in the bigger Nikon cameras like D200, D300, D500, D700, D800, D800E, D810, D850, D3, D3x, D4, D5, etc. Several analog cameras like the F100 use this connector too. It is also used by the Fuij S3 and S5 Pro. Nikon offers a cable called MC-22. It's an adapter cable for the round 10 pin plug ending with three banana connectors for own circuitry.

No connection...

Unfortunately the models D40 (2006), D50 (2005), D60 (2008), D70 (without s) and D3000 don't have a cable release connector. IR or USB-tethering are the only control options here.

Olympus E-system

RM-UC1 connector

olympus remote release connector pinout

This is the plug found on the Olympus RM-UC1 remote release. According to the Olympus web site it fits the models:
E-P1, E-P2, E-P3, E-P5, E-PM1, E-PL2, E-PL3,
E-30, the E-400 series, E-510, E-520, E620,
OM-D E-M1, E-M5, EM10, etc.

It's also compatible with the compact cameras:
XZ-1, SZ-20, SZ-30 MR, SP-565, SP-570 and SP-590.

RM-CB2 2.5mm jack connector

Pinout wired remote control

With the OM-D E-M1 Mark 2 Olympus is switching to the simple 2.5 mm jack connector also used by Canon or Pentax (Thanks for the info Eric!). The corresponding remote control is called RM-CB2.

RM-CB1 connector

olympus remote release connector pinout

The plug shown above can be found on the older Olympus RM-CB1 remote release. Compatible camera models are E-1, E-3, E-300 (via battery holder), E-10 and E-20.


lumix remote release connector pinout

Panasonic/Lumix goes an unusual way and uses just one wire to control the focus and the shutter. As shown in the picture above, only the shaft and the first ring are used. Resistors are used to choose the function.
This connector can be found in the DMW-RS1 and DMW-RSL1 remote control from Panasonic and is compatible with the following camera models:
G1, G2, G3, G5, G6, G7, G10,
GH1, GH2, GH3, GH4,
GX1, GX7, GX8,
FZ25, FZ30, FZ50, FZ100, FZ150, FZ200, FZ1000, etc.

My experiments showed that the more common resistor values of 33k, 3k3 and 2k2 also work. A possible wiring of the cable is shown here. Note that the grounds of the plugs are not directly connected.
If you are building the cable yourself, I recommend to recycle the 2.5mm side from a ready made cable to avoid buying and soldering the 2.5mm 4 pole plug.
Some of the Lumix cameras (e.g. G3, G6, FZ1000) have the remote plug on the right side. This is not typical and a longer cable will be needed.


Pentax are the good guys and use the common 2.5-mm stereo jack plug. The pinout is the same as for Canon cameras (see above). These models can be connected using the jack plug: 645Z, 645D, K-1, K-3, K-5, K-5II, K-5IIs, K-7, K-50, K-500, K-30, K20D, K-m, K10D, K100D and K110D. Unfortunately the K-r and the K-x have no remote control socket. These models can be released per IR only. Pentax standard wired remote shutter release is called CS-205.

Sigma (SD-14, SD-15)

The plug is the same like Canon, but the shutter and focus pinout is swapped. Thanks to sigma_fan for providing the info!


Sony has currently two types of connectors.

Old Minolta Connector

In the bigger models Sony uses the old Minolta connector shown below. The A77ii proved also to work with this cable.

sony remote release connector pinout

Multi Terminal

The newer and more compact camera models use a connector similar to a micro-USB port but equipped with an additional row of contacts for extended functionality. In the image below you can see the front row and the standard USB contacts with a larger pitch in the background. The plug is about 3 mm longer than the standard micro-USB. Sony uses the same trick for their Multi interface shoe to make their own equipment and older flashes compatible.
This plug can be found in the Sony RM-VPR1 remote. It fits the models:
RX10, RX100ii, RX100iii, RX100iv,
ILCE 3000,
A7, A7ii,
A5000, A6000,
SLT-A65, SLT58, etc
In the plug I analysed the ground was on the metal housing. Other sources specify the second pin as ground. The other pins have other functions like zooming, but need a special protocol.

No Connection

Several Sony models do not have a remote connector and can be controlled only with a wireless remote.


No guarantee for nothing. Please be careful when experimenting with your camera.

Pinouts of Kodak dcs pro plus and Hasselblad H digital backs?
Hello everyone,

I would like to use a KODAK DCS PRO BACK PLUS on a Hasselblad 500el / m. Does anyone know the wiring diagram of the Kapture group Pro Shot release cable for mechanical cameras or the pinout of the 7-pin Lemo socket?

In another project I converted an H3D-39 Digiback to the v-System. The power supply is currently only over the Firewire800 port. Does anyone know the pinout of the databus connector on the mounting plate of the back?

Thank you very much and greetings from Berlin.

Sigma CR-41: not really needed
Sigma CR-41: not really needed.
I don't have the Sigma CR-41 actually, but rather bought a 10' release for $10 marketed as Canon/Sigma compatible. The one I got has a sliding 'hold' function and a button to just shoot (you'll find the model resold by everyone). Been working flawlessly for almost a decade on two different model Sigma bodies (but none are FP series). I also bought a $1 housing, some thin gauge wire and a 2-stage DPDT switch for a couple bucks, and it also works well (you can't go wrong with the Sigma/Canon switching: it's foolproof.

Olympus E-M1X shutter
Great info, thanks.
One possible clarification with the Olympus E-M1X:
It appears that the 2.5mm jack connection needs the 'Focus' connection to be closed when the 'Shutter' is triggered. Otherwise the camera doesn't respond to some camera functions after the photo is taken.
After taking a photo without the 'Focus' contact being triggered, unplugging the cable restores correct operation of the camera.

Sony RX10 iii Solution
I figured it out. I don't know exactly what wires correspond to which Port on the slim USB, but I actually got myself a button and disassembled it. One can still short the focus and the shutter.
Here is a post that helped me where you can also find a picture of the disassembled Sony remote: a-external-trigger-what-is-the-shutter-signal?noredirect=1#c omment1483634_567279

Sony RX10 iii
I tried to do the "connect shutter to ground" protocol, focus first then shutter or both at once, but the only thing that works is focus green cable).
I modified a RM-SPR1 Remote that I wanted to be controlled externally by a microcontroller with an optocoupler.
I have seen that maybe resistors are needed?
Does somebody know how I can release the shutter?

#61 - Richard - 05/25/2021 - 11:03
Did you get a chance to dig into Sigma CR-41 Cable Release Switch for Sigma fp Digital Camera yet? I have a DIY project that will fire the Sigma fp through CR-41 cable and it's stereo jack.

Sony Multiport to Micro Usb
Hi all,
I would like to build a Sony multiport to micro usb cable to be able to control my Sony a6500 with a Zhiyun crane. I already have the original cable but it does not allow me to use an external monitor, because the angle of the connector is downwards.
Do you think I can use the pinouts of the remote shutter?


#59 - Name - 04/09/2021 - 09:15
Thanks to your excellent research, I was able to confirm that the new Fujifilm X-S10 also uses the same "Canon protocol" as most of their older X series cameras, although with a 3.5mm plug.

Sony RM-VPR1 mulyi-terminal cable
Hello, I hope someone here can offer me advice. I have lost the multi-terminal cable that came with my Sony RM-VPR1 and enabled me to control power on, focus, and shutter release on my Sony RX10 M3. Sony cannot supply a replacement cable and don't seem able to respond to questions about wiring. Can anyone tell me where I could get a replacement cable or, alternatively, advise me how to make one.
Thanks in anticipation.

Panasonic S1 Shutter Issues
Thanks for the info. I’ve tried to do something similar for the Panasonic S1 but have had no luck. This camera seems to prioritise firing the video record function. The video record fires at no resistance up to around 22k. Further resistance stops the video firing but nothing else happens. I just cannot seem to get the shutter to fire for stills.

Panasonic Purpose to 36K Resistor?
Great page, thanks for putting all this together!

I'm working on an IR shutter release for a G5, and wondering what the 36K resistor is for. The 2.9K is fine, combined with the 2.2K it's pre-focus; the 2.2K alone works the shutter; but the three resistors together - 41.1K - doesn't seem to serve a purpose. Does it just tell the camera that there's something connected? Any other ideas?

the RR-80 usb tweak works also on Fuji XT-2
I had an issue with amechanical defect in my Fuji XT-2 2.5 mm socket. I have tried to use the RR-80 txeak with the bmicro usb connector and it does work. I was looking for release only (no focus issue) and in that case a simple short without resistor between pin 4 and 5 works perfectly.

Sony A series
You will probably know: I tried to short the jack to multiport adapter to trigger the camera, but it does not work. It does work though when the jack is inserted in the specific button command. I wanted to adapt a pedal trigger for duplication work. Does the circuitry need some type of resistor to be recognised by the camera? Many thanks!

Sony Alpha multiport 15 pinout question
Thank you for response and Hello again:
My problem is this: I need shoot sony alpha cameras joining only 2 contacts.
1: If in my system I want use the camera only en Manual Focus. what contacts should I use for shoot the photo? Only the 2 and 4?

2: What contacts should I use if want use automatic focus too if I only having only posibility of join 2 contacts in the external trigger?

3: ground is number 2 or should I use metal housing of conector too?
In that case; Should keep joined number 2 with metal housing?
I have made some triggers with 4 and 5 joined and shoot when conect to ground, but in some alpha cameras seems not work this.

Cameras that I'm having problems are; Alpha 6000, 6300, 6500 Nex3N and similars.

I wait your answer. Thank you very much.
Greetings for you

Sony triggering
Hi Mario,

I don't know if you need to pull down both shutter+focus or if the shutter is enough. It's safer to pull down both. Please don't connect the shutter and the focus wire permanentely. If you do this, pressing t
he release button on the camera half-way to get the focus will release the camera because of the externa
l connection of focus and shutter.
You can use a diode between the focus and shutter line if you want to avoid a second transistor. Here is an example how to do it:

Regards, Luk

Sony USB-C connector
Hi Martin,

that's interesting. I don't have the information yet. The Multiport was a mix of Micro-USB and Sony's own plug. The USB-C seems to be too packed for such kind of tricks. Maybe you can compare the RC plug to a regular USB-C plug visually. I guess the plug is standard, but some resistors are used to code the functions, like with Lumix. Any feedback is of course welcome. I would like to try out the Smatrig with the very new Sonys.

#44 - Luk - 12/15/2018 - 09:54
List of supported compact cameras
The website is great! congratulations for your inspiring work.

I wonder if there is any detailed list of compact cameras that support external shutter control. I am thinking about Sony, Lumix and Canon below 400 Euro.

Remote relase pin connections
First I want to say thank you for posting this great document. I have read all of it and I like to know that using the different Cabled for different cameras do I need to connect the Shutter wire with the focus wire and then when it is shorted it will focus and then release the shutter and take the picture.
I understand that some may need battery or resistor so I am not talking about those cameras.
I am new with cameras so please forgive me if I ask some questions that might be simple to you or others.
My purpose of doing this is to make a automated picture taking wireless but I need to make the cables first, yes I understand there are many wireless in the market but I am using Arduino which will send signal at certain time and events for the camera to take the picture and I need the make the cables for my receiver to connect to the camera. I tried to just have the shutter cable connected to ground but nothing happens however when I connected the shutter and the focus wires together and then grounded them the picture was taken so my question is DO I HAVE TO CONNECT THE FOCUS AND SHUTTER TOGETHER OR NO NEED. IF NO NEED, THEN IS THERE A SPECIAL SETTING THAT I HAVE TO DO IN THE CAMERA SO BY JUST SHORTING THE SHUTTER WIRE TO GROUND WILL TAKE THE PICTURE.

I do want to thank you ahead of time for taking the time to read my email.

I look forward to your reply.

Thank you,

Hello John,

with 6k resintance, the opto-coupler is not triggered strong enough and the camera is not responding. Adjust the resistor btw the uC and the opto-coupler for a current of about 20-50 mA. This is the current the IR-LED needs to trigger the output properly. Post a link to the schematic for easier debugging.

[1] Many thanks [2] Panasonic Lumix FZ1000 has 3.5mm 4 conductor receptacle - not 2.5mm
The Panasonic DMW-RS1 shutter release uses a 2.5mm 4 conductor plug that works on most Panasonic dslr cameras. However the Lumix FZ1000 camera has a 3.5mm receptacle for the shutter release. I have just now ordered an adapter plug with a 3.5mm 4 conductor male and 2.5mm 4 conductor female hoping this will work.

Sony Multiport cable providing both USB and shutter remote
I've never seen such a dual purpose cable for Sony, but I like the idea. If you have the USB->Sony cable, you can try to measure which pins are used for USB. Getting the Sony plug with both options wired might be a problem.
