Preview and taking stop-down: problem?
The lovely F4 I have been posting about may have a serious problem.
I don't know why I was even fiddling with it, but I noticed the aperture (several lens, inc. AF 50/1.4D and AF 24-50/3.3-4.5) Dont seem to stop down farther than F8 when I operate the preview lever. As I move the aperture ring, it closes to F8, then doesn't seem to move. Off the camera, or on my D7K digital, the lens does as I expect. Also, looking into the mirror box with no lens mounted, the stop-down lever only travels slightly more than half its length (I know that will vary according the smallest aperture of the lens mounted, but my D7K lever moves to the bottom of its range). No evidence of over-exposure on the photographs (if anything, slightly under exposed). When I received the F4 the preview lever was sticky, wouldn't always return when released, but applied a little alcohol and it returns as normal now. So I am wondering if I even have a problem (maybe I am mistaken about how the lever on the F4 is suppose to operate, and if so, what to do. Any tests to recommend? Alcohol on the stop-down lever, other simple home fixes, or to the camera doctor? Thanks.
EDIT: I should have mentioned that I set the shutter to 2 sec and F8, then F16, and it also appeared not to stop down fully at the smaller aperture. Tried this twice, and again with a second lens, same thing.

Might be a good idea to take it to Camera Clinic on Tuesday (or one of the days through Saturday)... See what Doug has to say about it... Something's not right. If it needs major work, consider looking at the boxed F4s that he has. Everything works on it, and, if you want, I'm sure he'd be willing to move all the cosmetic pieces from yours over to it, so it'd be like using your camera, just with everything working properly.
Just checked mine, and it works normally.

Thanks, John. Doug is working on it. Not cheap, but if you ever have the chance to see the condition of mine (and not just cosmetic), and the fact I paid $200 for it (and with the MF-23 back and an OK wide-normal AF zoom included), it made sense to fix it. I did almost buy your former F4S, which is good looking and an ace-shooter (if anyone is looking for one, it is still there as of this post, 100% working, warranteed, and at a good price), but now I'll have a perfect shooter, as well as a camera that looks new. Next best thing to having bought one "back in the day," for a fifth the original price. Not cheap, but in the long run, not really expensive either, considering what I get.
And so far, Doug and Camera Clinic have lived up to their excellent reputation. How many businesses have not only very high ratings, but in a thorough internet search, not even one niggling complaint I could find, ever? Track the other locals, and just about anywhere, and not many have such a stellar record.
Oh, and in playing with the F4S, with its 6 lithiums, I can attest that they are fine, regardless of Nikon's hemming & hawing, and certainly do speed things up noticeably.

Follow-up a bit later: all fixed. And I do mean all. The aperture-couple problem repaired, and full CLA/pro inspection, and I have never examined a camera so thoroughly subsequently (not that I didn't accept Doug's assertion of a clean bill of health, but it was a bit of a heartache to have my beautiful baby, purchased on the cheap, fail so basically earlier (not to stop down smaller than F8!), I got a bit obsessive, which I know is SO unusual among us, trying every permutation of everything I could possibly think of, and again, verifying all on film. I would have been content NOT to shell out another chunk, but now I KNOW to about 20 decimal-places that I have one very fine F4, without even minor defect and ready for a thousand or more rolls of film, even suitable for a serious collector's main example (though none of my working cameras are shelf-sitters, nor will ever be)
And FYI if you are within 50 miles of Shoreline WA/Seattle: Camera Clinic is just a terrific place and does truly great work (meaning they make things work, they don't just R&R parts and shrug when something else goes wrong). Turns out Doug has all sorts of Nikon stuff for sale as well, a lot of lenses at prices right at the middle of the market, and some bodies, and a lot of remarkable things, just ask him., all copies you can examine and rely on like few you'd ever find online, which actually makes the "average" prices cheap. I am kind of glad Doug doesn't have a website, with all the stuff he has there listed & priced. Or I'd be up there every week spending money!
