paul hart Posted March 4, 2009 Share Posted March 4, 2009 <p>Had my D700 for some months now so fairly well used to it. However, unless I'm missing something I think it has developed a problem.<br> In aperture priority mode, the sub-command dial is intermittently refusing to alter the aperture. As I write, it has the new 50/1.4G fitted and it won't budge from f2.5; I turn it off, switch to my 35/2.0D and it sits at f32, refusing to move.<br> I switched it to M mode, and the dial is still out on strike.<br> Am I missing something somewhere, or is it a trip back to Nikon?<br> Thanks.</p> Link to comment Share on other sites More sharing options...
mike grossman Posted March 4, 2009 Share Posted March 4, 2009 <p>I don't think you're missing anything. I think, unfortunately, it should be returned or serviced.</p> Link to comment Share on other sites More sharing options...
rick_donnelly Posted March 4, 2009 Share Posted March 4, 2009 <p>I've experienced a similar failure on a nikon and a contax. The rotary switch was not working properly and had to be replaced.</p> Link to comment Share on other sites More sharing options...
ShunCheung Posted March 4, 2009 Share Posted March 4, 2009 <p>Just in case: the command dials on the D700 can be locked, individually. Check the appropriate custom settings. I doubt that this is your problem, but you might as well double check.</p> Link to comment Share on other sites More sharing options...
david-m Posted March 4, 2009 Share Posted March 4, 2009 <p>Maybe there is one thing that you missed - I think that when you have reviewed a shot on the screen, then you have to activate the dials by half pressing shutter-release again. <br> It's worth a try.<br> David</p> Link to comment Share on other sites More sharing options...
paul hart Posted March 4, 2009 Author Share Posted March 4, 2009 <p>Many thanks for these helpful answers. Looks as if it's going back. Now where's my Leica M3...</p> Link to comment Share on other sites More sharing options...
paul_b.1 Posted March 4, 2009 Share Posted March 4, 2009 <p>The main command dial controls the sutter speed as default, and the sub CD control the apperture. However, you can change the main/sub functions between the two. In this way it become clear that you have (or not) a mechanical malfunction of the subdial wheel .</p> Link to comment Share on other sites More sharing options...
galileo42 Posted March 4, 2009 Share Posted March 4, 2009 <p>I would first check what Paul B. suggests: main dial for speed, sub-dial for aperture. Reversed with CS f9, «Change main/sub». Worth trying.</p> Link to comment Share on other sites More sharing options...
paul hart Posted March 4, 2009 Author Share Posted March 4, 2009 <p>Thanks for the suggestions. I tried that, and it made no difference.</p> <p>The odd thing is that if I leave the camera switched on, the fault seems to rectify itself after an indeterminate time and all works well.</p> Link to comment Share on other sites More sharing options...
ShunCheung Posted March 4, 2009 Share Posted March 4, 2009 <p>The connections/contacts inside the dial are probably loose. Sounds like it is time to send it back to Nikon for repair.</p> Link to comment Share on other sites More sharing options...
