cdzombak Posted July 31, 2008 Share Posted July 31, 2008 I recently bought a used N90s, in excellent condition, from KEH. Generally, it seems to work wonderfully and Ireally like it. However, I think there is a problem with the mechanical aperture coupling on the camera. The camera usually cannot use the lowest aperture on a lens I put on it. Let me provide some examples:1) With my Nikon 24mm f/2.8 AF-D or Nikon 35-70mm f/2.8 AF-D, the widest aperture the camera can read is f/4.2) With the Nikon 50mm f/1.8 AF-D, the camera sometimes reads f/1.8, but usually f/2. All of these lenses work perfectly on my D70s. I haven't tried yet with any other lenses, and I haven't run anyfilm through the camera yet. I don't know whether the camera stops down to the selected aperture or not when youactually take a photo. I'm pretty sure it would, but still, an incorrect aperture reading will mess up the metering. Is there a simple adjustment that can be made to fix this?Should I take it to my (semi-)local camera store (Huron Camera, Dexter MI for the record) and see if they can fixit? Send it to Nikon? Should I just try to get a replacement from KEH? Link to comment Share on other sites More sharing options...
cdzombak Posted July 31, 2008 Author Share Posted July 31, 2008 Well, please disregard this post I guess. After many (>15) lens changes in testing, and switching to program mode and back, the camera seems to be functioning well again. I should've done more tests before posting (although I also did a ton of tests before posting). Oh well. I'll also clean the contacts on the lenses and body for good measure. Oh, and one more observation: AF on that thing is noisy! I'm used to the D70s, and the N90s is even worse. Another observation: I *love* this viewfinder. I wonder how the D300 viewfinder compares? I might get one... next year-ish :( Link to comment Share on other sites More sharing options...
User_276104 Posted August 1, 2008 Share Posted August 1, 2008 Regarding the viewfinder, yes - the viewfinder on an N90s is a huge improvement over a DX DSLR. It blows away even a D2x. After shooting my D2x exclusively for a few months, I went back to a N90s and couldn't believe how bright and clear it was. I haven't handled a D300 myself, but it's still a DX camera so the viewfinder most likely is still a far cry from FX or film bodies. Even though you say the camera is working OK now, I'm still a bit curious as to the problem you encountered. You didn't mention much about what modes you tried, except for one mention of P mode. A camera like the N90s relies on mechanical coupling for aperture information in A and M modes, with that little tab at the 1 o'clock position as you face the lens mount. Maybe you know that already; I don't know. It's possible that the camera hasn't been used in a long time and needed a little "waking up". Link to comment Share on other sites More sharing options...
cdzombak Posted August 1, 2008 Author Share Posted August 1, 2008 Maybe I just need a D700, then :) I should've mentioned that I was using it in A mode. It does seem like the camera did just need some "waking up;" I hope to put one or two rolls of film through it this weekend. Link to comment Share on other sites More sharing options...
joemoree Posted August 1, 2008 Share Posted August 1, 2008 I learned and still use with a N90s, on A mode it should allow you to choose your aperture. I would call KEH if the problem persists. I love that camera! Link to comment Share on other sites More sharing options...
glockman99 Posted August 1, 2008 Share Posted August 1, 2008 ...Glad to read that your N90s is working as it should. Now, if you really want a treat, screw on a MB-10 Power Verticle Grip to the bottom of your N90s, and enjoy the excellent ergonomics that this combo provides.

cdzombak Posted August 3, 2008 Author Share Posted August 3, 2008 I'm planning to pick up an MB-10 pretty soon here... I'm really looking forward to it! Link to comment Share on other sites More sharing options...
