Camera remote release pinout list
CanonNikon
Pentax
Olympus
Sony
Panasonic/Lumix
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.
Canon
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
This connector is used with the EOS 350D, 400D, 450D, 500D, 550D and the 60D. The last type is the only 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 any bigger electronics store. The 'official' remote controller with this plug sold by Canon is called RS-60 E3.
N3 Connector
This connector is used with the EOS 10D, 20D, 30D, 40D, 50D, 5D, 5Dmk2, 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.
Nikon
With three different types, Nikon is the unbeaten leader in inventing remote release connectors.
MC-DC1
This type fits the D70, D70s and D80.
MC-DC2
This type fits the D90, D3100, D5000 and D7000. Probably it was introduced because of 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)
This is the connector found in the bigger Nikon cameras like D200, D300, D700, D3, D3x etc. 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...
Unfortuntely the modells D40, D60 and D3000 don't have a cable release connector.
Pentax
Pentax are the good guys. All Pentax cameras can be triggered remotely via a simple 2.5-mm jack plug. The pinout is the same as for Canon cameras (see above).
Olympus E-system
This is the plug found on the Olympus RM-UC1 remote release. According to the Olympus web site it fits the modells E-PL2, E-P2, E-P1, E-620, E-30, the E-400 series, E-510 and E-520. 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.
Sony
Sony has a rather exotic connector fitting all types. Many modells do not have a remote control connector. Both focus and shutter must be connected to ground to release the camera. Shutter only doesn't work. The connector was invented by Minolta before Sony bought them.
Panasonic/Lumix
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 is used by the Panasonic GF1 etc.
Experiments showed that the more common resistor values of 33k, 3k3 and 2k2 also work.
Disclaimer
No guarantee for nothing. Please be careful when experimenting with your camera.





Is there any adapter or cables+adapters combination to convert mc-dc1 shutter cable to mc-dc2 shutter cable type. I got a 5 meter shutter cable for d80 that I want to fit to d90 camera.
Many thanks !
