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 the EOS 350D, 400D, 450D, 500D, 550D, 60D and the 70D. 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, 6D, 7D 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.


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

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


nikon remote release connector pinout mc-dc2

This type fits the D90, D3100, D3200, D5000, D5100, D5200, D7000, D7100, D600 and D610. It was probably 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, D700, D800, D800E, D3, D3x, D4, 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.


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). Unfortunately the K-r and the K-x have no remote control socket. These models can be released per IR only.

Olympus E-system

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
It's also compatible with the compact cameras
XZ-1, SZ-20, SZ-30 MR, SP-565, SP-570 and SP-590
One user reported that plugging in the remote cable into his E-520 blocks all controls on the camera body. The settings have to be done before attaching the cable.

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


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

The newer, more compact camera models use a connector similar to a micro-USB port but equipped with more contacts, see below. This plug can be found in the Sony RM-VPR1 remote. It fits for example the A7, A6000 or SLT58 camera. 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.

sony rm-vpr1 remote release connector pinout

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


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 to the cameras:
G1, G2, G3, G5, G6, G10,
GH1, GH2, GH3, GH4,
GX1, GX7,
FZ25, FZ30, FZ50, FZ100, FZ150, FZ200, FZ1000,
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 might be needed.

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!


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


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


Sony RX100 m2
I would like to trip the shutter remotely while flying FPV. Thought it would work with my iPad app but that is only good for about 20-30ft. I'm not that bright about electronics and was hoping someone has a fix. Earlier I had purchased a sony RM-VPR1 remote but found out it needs to be tethered,
that idea is out.

remote triggering - #2
My apologies - since the last post I've done a bit of research and answered my own question - USB triggering is obviously a completely different process involving an exchange of data, rather than the simple circuit closure performed by remote cables and intervalometers. I've solved my problem by using a Raspberry Pi to communicate with the camera via USB. A bit more expensive than an MC-36, but cheaper than buying a new camera!
#41 - mike_m - 01/04/2015 - 13:54
remote triggering
I'm using an old Nikon D40 to do timelapse. I can trigger it remotely from my PC using the Mini-B USB socket on the camera; however, I would prefer to use a dedicated intervalometer if I can. So my question is, what is my PC doing when it triggers a shot on the D40 via USB - does it simply close a circuit, or is it supplying a more complex signal? If I knew, I could perhaps modify an MC-36 to do the same job.
#40 - mike_m - 01/02/2015 - 11:24
thanks for confirming the D7100 pinout. I do not provide the color codes since I usually reverse-engineer no-name remotes. Here the colors differ from manufaturer to manufacturer.
#39 - Luk - 12/21/2014 - 21:46
The pinout guide you have for the Nikon D90, D3100, D3200, D3300, D5000, D7000, focus/shutter MC-DC2 connector ALSO applies to the Nikon D7100 - I know because I've got one and I have made up remote leads for it.

Also, the older MC-DC1 uses a different colour code to the MC-DC2. On the MC-DC1 Nikon uses Black for ground, green for focus [red on MC-DC2] and white for shutter release. Just to confuse matters, the same FOUR core cable is used in BOTH, [red or green cut off as appropriate].

Hope this helps - Mike

re: panasonic zoom : use WIFI
see how you can control power zoom on GH4 via wifi

Another handy feature built into the camera is WiFi. Download the free Panasonic Image App and you have the ability to control many features remotely including start/stop video, change color profiles, set white balance, ISO, framerates, and resolution.

Panasonic GH4 Zoom Control ober 2,5mm Jack
Does anyone have an idea how the protocol or the connection diagram works for Panasonic 2,5mm Jack to control the zoom??
It is possible, as proved here:

I want to control this features over an RC Remote, i can release the shutter with this cable:

But there is no possibility to control the zoom. I am really freakting out because i cannot find any solutions or diagrams.

Maybe somebody has an idea???
Thanks very much

Alternative for Brinno?
Does anyone know if there are alternative remote control cables for a Brinno TLC? Picture here:
Looks like a Panasonic or iPhone jack plug, but I'm not sure. The Brinno cable is extremely expensive...
#34 - Jos - 05/11/2014 - 12:55
First of all, thanks for the great article!
It turns out, that at least on the Sony A57,that it is only needed to connect shutter to ground, without the need of connecting focus, just as long the lens is set to MF.
#33 - Nicklas B - 02/13/2014 - 14:13
Of course, the correct name of the adapter cable to be \"hacked\" (see other post) is Sony VMC-AVM1, not Sony VCM-AVM1.

Remote Control for Sony cameras with \\\\\\\"Multi Terminal\\\\\\\" (since 2012)
Sony abandoned the classical 3-pin remote release port (which was found on almost all Minolta, Konica Minolta and Sony Alpha cameras since 1985 so far) in 2012. The cameras can still be released per IR remote release and be controlled via USB (tethered shooting).

Since 2012 all new Sony cameras feature a USB 2.0 HighSpeed micro B connector rather than a USB mini B or a proprietary USB connector.

On most of these new cameras, however, the USB micro B connector is not labelled \\\\\\\"USB\\\\\\\" but \\\\\\\"Multi\\\\\\\" in order to indicate that it is a special Multi Terminal connector.

This Multi Terminal connector is compatible with a standard USB micro B connector but features 10 hidden contacts carrying additional signals for:

- power
- composite video out
- stereo audio out
- remote release

Fortunately, the old 3-pin remote release interface is available here as well. While the proprietary Multi Terminal connector is not readily available, it is possible to \\\\\\\"hack\\\\\\\" a passive remote release adapter cable utilizing a (relatively cheap: 20-25 EUR) Sony VCM-AVM1 adapter cable.

Old 3-pin remote release:

R1 (\\\\\\\"C\\\\\\\") = ground / shield -> outer ring
R2 (\\\\\\\"F\\\\\\\") = activate camera / focussing -> middle ring
R3 (\\\\\\\"S\\\\\\\") = release shutter -> center pin

New Sony Multi Terminal:

M1 VBUS (+5V in, max. 2A)
M6 +3.1V (for LANC_DC etc.)
M7 reserved
M9 reserved
M10 SELECT (resistor against M6 or M14)
M11 Audio R out / activate camera / focussing
M12 Audio L out / release shutter
M13 Composite video out
M15 reserved

Not all functions may be provided by all camera models.

3-pin to Multi Terminal adapter cable based on a hacked VCM-AVM1:

M11 -- middle ring (\\\\\\\"F\\\\\\\") -- R2
M12 -- center pin (\\\\\\\"S\\\\\\\") -- R3
M14 -- outer ring (\\\\\\\"GND\\\\\\\") -- R1

More details can be found in this forum thread at Minolta-Forum:

Hope it helps,

HI, i have a SONY NEX VG900 it has a D shape(10 point) type AV connector for a remote. The problem is i can not find a intervalometer with this type of connector, to trigger the shutter. does any one know how this connector work and what the ten pins do ???. Cheers peter

Hello dear friends! I have done a macro rail for focus stacking. I used a 16f877 TQFP or a 16f877a TQFP, an step by step motor, etc... and a optocoupler. In my Canon Kiss X50 or 1100D is works great but in a Nikon d7000 not. Could it be a problem in voltage? The optocoupler is a PC817.

Time laps trick with motion
HI. I'm thinking if this is just a switch or connection of tow wires (ground+shutter) = bulb ... then...
The timers /auto shutter remotes those are easily available in markets are only connecting these (ground+shutter) wires after a set of intervals.
My Question is...
..i have a DC motor, that is attached with some mechanism (i made) with RAIL + MY DSLR CAMERA.. if i power that motor, this camera drags on the RAIL... is it possible if i connect the same timer as parallel connection to the camera for timelaps and the motor to drag a bit after every interval... will it be safe for camera.. because.. to switch on the motor i use power and in camera only two connector is being connected..

I hope you understand my question.
Thank you

D90 vs, D300/3100/3200/5000/5100/7000
Its worth pointing out that the orientation of the socket changed from D90 compared to all the others (D300/3100/3200/5000/5100/7000). This is only an issue if you boought a device (say, a GPS) for the D90 which has a right-angled connectore. If yu change to one of the other cameras your plug still fits but now the cable points the other way.

If you don't mind cutting the cable and re-attaching the wires the opposite way around, this can be fixed however.
#20 - Chris Lilley - 10/18/2012 - 05:41

2.5mm shutter release cables
The Pixel and Cactus V5 flash triggers also support a shutter release function, and use a 2.5mm 3 connection phono jack to plug into the flash trigger, and a camera specific cable to plug into the camera. sells these cables:

The ebay sellers foto4easy and also sell these cables.

Note, the phottix cables seem to be wired differently than the Pixel/Cactus cables. I think the Pixel/Cactus cables have the ground wire at the tip, the focus in the middle, and the fire closest to the cable, and the Phottix has it the other way around. However, be sure to test it manually yourself, no matter what cable you get.
#16 - Michael Meissner - 03/15/2012 - 17:33
I think it might have been these guys

But I seem to remember someone who sold cables with a 2.5mm stereo connector on the end opposite the camera connector. Phototix cables have a 3.5mm stereo connector. I would like to find those with the 2.5mm connectors.
#15 - Don - 02/28/2012 - 22:58
Sorry that I asked the same question twice but the first time it told me that I got the captcha wrong so I tried again. And that time it told me that there was already a post with the same information but I thought that the first post never went through so I modified the title and the phrasing of the post and tried again. Now I see that both went through and there is no apparent way to delete one of them. Oh well.

Thanks for doing this! I am now looking for a site that I visited once and can no longer find. It sells cables for a universal wired remote that they also sell.
