newshooter12 0 #1 June 4, 2006 Yes... i've looked and searched. Here's what I need. The info that Conceptus says they send with each stereo switch. Why: I'm planning to wire a MC-DC1 knock off plug to a female stereo 3/32" plug so that i can use the normal MC-DC1 end, a conceptus switch, blow switch or some other switch in the future without having to solder each time i switch it. I know the wiring colors from Conceptus that they put on their website, but they don't tell you which wire goes to Ground, R2 or L1 on the stereo plug. Can anyone help me with it. Jimmy if you're reading this... it's what i want you to do so you don't have to cut and hard wire a new swith each time your tongue switch breaks. So you'll be able to just plug in a factory fresh/backup tongue switch. matt Quote Share this post Link to post Share on other sites
jmidgley 0 #2 June 5, 2006 Hi Just to be clear, you want to cut the Nikon-proprietary plug off a Nikon remote, and solder a 2.5mm socket onto the end? This would allow to have that as a standard connection for different kinds of releases, including, as a bonus, the Conceptus. First, the Conceptus releases seem to be designed with Canons in mind, specifically the ones that take the E3-type release. If you look at this website, you can see how they work on a Canon. A 'full function' remote trigger allows you to separate the autofocus (that you get from a half shutter-press) from the actual shutter release. The conceptus switches are obviously just a single pole normally-open switch, so they have a couple of different strategies for what to do about autofocus. The stereo version allows you to permanently short (switch) the autofocus. If the camera is in some sort of continuous autofocus mode, it will continuously autofocus while the remote release is plugged in and the camera switched on. This obviously takes a fair bit of power. The second strategy is to short the autofocus and shutter release wires together permanently. Conceptus do this by using a mono plug, but I'd rather it was done by using a stereo plug and soldering the correct wires (ie, the two that aren't 'ground') together. When these two are connected to ground (ie, you bite the switch), the camera will seek autofocus and only then take the shot. Less power used, potentially long (certainly arbitrary) delay. The solution, recommended by Conceptus, is to use manual focus. See the thread about hyperfocal distance! Back to your problem (and apologies for all the background, which you probably knew already). If you know you never want to be able to separate the autofocus from the shutter release, you can simplify the job. Always buy the *mono* Conceptus, and get a mono socket to plug it into. That part of the system is just operating as an ordinary switch. Cut the Nikon remote wire and use a multimeter to find which wire is ground, which is autofocus and which is shutter. Typically ground is carried as a sheath of bare copper wires. Solder the autofocus and shutter wires together on the 'tip' terminal of the socket. Solder the ground wire to the 'ring' terminal. If you want the option to keep autofocus and shutter separate, you'll have to use a stereo socket (and get stereo Conceptus switches). Find the ground, autofocus and shutter wires from the Nikon plug/release and solder to the socket terminals as shown on the website above. Of course I might have completely misunderstood the question... John Quote Share this post Link to post Share on other sites
PhreeZone 20 #3 June 5, 2006 Thats not completely correct, Canon cameras with Conceptus switches have a 2 stage buttons where half in activates autofocus and all the way in triggers the shutter. I use Autofocus on my Canon with a Canceptus switch with good results.Yesterday is history And tomorrow is a mystery Parachutemanuals.com Quote Share this post Link to post Share on other sites
jmidgley 0 #4 June 5, 2006 Hi No, I don't think so. I got my info off Conceptus' website which states for both tongue and bite switches: 'Type - Single-pole, single-stage, normally open switch, sealed in flexible waterproof plastic' (here) Also: 'When used with Canon cameras in autofocus mode, the two standard plug types will yield different autofocus and metering characteristics. The mono plug will cause the camera to autofocus and meter constantly while the camera is on and the switch plugged in. This results in very rapid shutter reaction time at the expense of increased battery drain. This configuration works best when photographing freeflyers, freestylists, skysurfers, and other moving subjects. The stereo plug will cause the camera to autofocus and meter with each individual exposure. This increases battery life, but slows down the shutter reaction time. This configuration works best will large, relatively stationary formations.' (here) But re-reading this shows I have the mono and stereo characteristics the wrong way round. The *mono* plug shorts the autofocus permanently, causing the camera to continuously autofocus. while the switch is plugged in. John Quote Share this post Link to post Share on other sites

My Conceptus came with a stereo plug but it is definitely single stage... Hmmmm....interesting. My old stereo plugged switch was definitely a single stage. I just had it replaced with a new one (the dreaded pin-hole defect) and haven't tested it yet. It -seems- like a single stage upon playing with it but haven't plugged it into the camera yet. Let me know what you find out (still -way- too tired from the VERY HOT weekend to want to play right now).
