christian_kloumann Posted February 6, 2015 Share Posted February 6, 2015 <p>Hi from Norway :-)<br> I have just bought a mint condition Nikon MD-4 motor for my F3 camera.<br> I just had to get one again, because it brings back a lot of good memories from the 80´s.</p> <p>To someone of there, which still has a MD-4, could you be so kind and check one little detail for me ?<br> With batteries:<br> 1) Just take the MD-4, without the camera attached, and turn the mode selector to S or C.<br> 2) Then put the MD-4 motor close to your ear.<br> 3) When you push the trigger button half way down there is no sound.<br> 4) But when you then take your finger away from the trigger button, comes there now a tiny little electric/magnetic "click-sound"? <br> 5) The same tiny little click-sound also comes when I take my finger away, after pushing the battery-check button. Is it so at yours also?<br> With the battery-chamber removed, there are no sound when 4) and 5)</p> <p>This is just a detail, of course, but it would give a good feeling knowing if this is how it should be.<br> Thank you :-)<br> Christian</p> <p> </p> Link to comment Share on other sites More sharing options...
michael_bradtke Posted February 6, 2015 Share Posted February 6, 2015 <p>Hi Christian</p> <p>My MD-4 makes the same noise you are describing. I think it is just the switches clicking that we are hearing.</p> <p>Have fun with your MD-4</p> Link to comment Share on other sites More sharing options...
jose_angel Posted February 6, 2015 Share Posted February 6, 2015 <p>On mine (a moderately used unit), with half charged batteries (only one test light), there is no other sound than the springs in both buttons, or the clear switch "click" on the shutter release button when fully pressed. <br /> If I half-press the shuter button, and then take my finger away, there is no sound other than the mentioned springs inside. As far as can hear it, no electric or magnetic click. Same in the batt check button. There is no difference if I test it with or without the battery tray attached.</p> Link to comment Share on other sites More sharing options...
christian_kloumann Posted February 6, 2015 Author Share Posted February 6, 2015 <p>Michael and Jose: Thank you for answering me.<br /> Hmm..So one with electric/magnetic (tiny) "click" and one without...<br /> Jose: I can also hear (very tiny) the spring itself, but the electric/magnetic sound here is a little bit/sightly "louder"..<br /> Mine (absolute mint) has the serial number 227939</p> Link to comment Share on other sites More sharing options...
jose_angel Posted February 7, 2015 Share Posted February 7, 2015 <p>Out of curiosity, I have tested it again with full charged batteries; same results.</p> Link to comment Share on other sites More sharing options...
User_5050610 Posted February 7, 2015 Share Posted February 7, 2015 <p>Christian--my MD4 makes the same noise. Would not worry about it. They are incredibly rugged little machines. Made for the photojournalism/other professional groups. I have one on which the the metal grip in front is extremely worn--it's a little noisy (gears) and it still works fine. This particular one must have seen thousands of rolls of film go through an F3--the stories it could tell! I'd just use the one you have. The ONLY disadvantage of an MD4--IMHO--is the weight it adds. Good luck!<br> Paul</p> Link to comment Share on other sites More sharing options...
lex_jenkins Posted February 7, 2015 Share Posted February 7, 2015 I didn't notice any particular or unusual clicking on my MD-4 yesterday. A halfway press of the motor drive shutter release button engages a physical detent which produces a barely audible click when the batteries are removed. It's inaudible over the noise of the motor drive. The main problem with my battered old MD-4 is intermittent battery contact. Occasionally I need to remove and replace the battery pack to restore the connection. I mostly use it from a tripod. The motor drive helps minimize shifting between frames because I don't crank the advance lever. Link to comment Share on other sites More sharing options...
donbright Posted February 8, 2015 Share Posted February 8, 2015 <p>Lex, I had the same intermittent battery contact issue. I solved it my going with Duracells, verses energizers. Energizers have a small dimple on the negative side of the battery. When installed inline, the result is a shorter length to the contact points in the clip. Duracel negative sides are flat, therefore increasing its total length when stacked adding more pressure to the contacts.</p> Link to comment Share on other sites More sharing options...
