"sporadic D90 shutter hesitation"


Wayland, US
          

Over the past few weeks I have started to notice that the D90 will sometimes hesitate about a half second before the shutter trips. Even though this has happened relatively few times, this is simply not normal and is thus noticeable (and jarring) for just that fact alone. First, my normal settings:

M- manual
AF-C
AE-L/AF-L button set to AF-ON

I've been through the menus several time now and as far as I can ascertain the camera is not being asked to evaluate anything before actuating the shutter train. The shutter should click immediately even with the lens cap on at midnight in a light-proof bag. My finger habits are well set and I am not experiencing crosstalk from autofocus. This is sporadic. As I said this has just started happening and I think I have noticed that it happens most (perhaps only) when the camera is waking up after a period of disuse (on the order of hours - the camera is shot almost daily). However, if this is true, the hesitation will have to be taking place after the camera has been turned on for a while and 1., the shutter button has been half-pressed to wake it up (if necessary) and 2., the thumb button has been depressed and focus acquired (judged visually - there is no beep in AF-C). In other words, the camera has no excuse for acting sleepy. If the hesitation takes place, it seems not to repeat itself for as long as the camera stays active over the next few hours. Does the camera ever refuse to take a photo? No, it's just slow off the mark by about a half second when it happens.

Is it the lens? Good question. I have been using two lenses in the time this problem has become apparent and I simply cannot say either that the behavior is confined to one lens or the other or has or has not occurred with both. But, neither of these screw-drive lenses (Tamron 17-50, Micro Nikkor 105 2.8D) has reported an FEE error, ever, on any body I own. There may be other less drastic faults that don't report out but I would have assumed they would be nulled out by using AF-C.

So my question is, before I go haring off to Nikon, has anyone else experienced or diagnosed this sporadic hesitation. If it's too sporadic, a trip to Melville is not likely to do much good and may only serve to irritate me. If it's a poor contact in the shutter button or its cabling (my fondest hope) then I guess I can cope - but I don't have to like it . This problem doesn't seem easy to find either here on Nikonians or on Google. However, at the very least, it would be interesting to know if there are some other secret sufferers. I suspect there are a couple of weeks of data collection ahead of me before it will make sense to contact Nikon.

Best,

Hendrik

I then bought the 17-50 with stabilization and it did the same thing so I retuned it ,no problem with my Seven other lenses.

Thanks, Mike. I suspect we're seeing different things but I'll certainly keep this in mind. For instance, I absolutely know that the last time it happened the Micro Nikkor was mounted.

Best,

Hendrik

You didn't have the shutter delay activated by accident did you? I sometimes forget that I have that turned on.

Sadly, no - but thanks. Since the problem clears without my doing anything, usually on the next shot, if it is a setting, the fault is somewhere in the circuitry and not my oversight. Also, the D90 is seldom on a tripod and I must admit I have never had the ambition to locate the shutter delay. Thanks for the tip. Yep, there it is, d10. Cool.

Anyway, my working hypothesis is a corroded contact in the shutter button or in one of the associated solder joints that connect it to a board. If a lot of folk experienced this problem then I might have a prayer of having Nikon do something about it. I don't mind the camera having a quirk, so long as it doesn't really get in my way.

For instance, the D70 has lost a few segments of the shutter count numbers on the top LCD but I've learned to translate. Same with its sporadic CHA errors. Quirky, minorly annoying but nowhere near fatal. No camera is forever, but then, neither am I.

Best,

Hendrik

That's too bad, it's never as easy as that

I did a little reading up and to me it seems like it could be an issue of contact between the lens and camera. Is everything clean looking on the camera and lens contact points?

The contacts on the camera body and lens are spring loaded to allow for lens attachment and removal. It is possible that one or more of the contacts is depressed or is not making contact to the opposite contact. It is also possible that the lens in not fully and correctly seated and contact is intermittent.

The voltages use for IC circuits is very low and invisible dirt or oxide may prevent proper contact. A visual inspection might not see the dirty contact. Many use a liquid contact cleaner and oxide inhibitor.

It could also be a difficult focus target to detect. Not enough contrast or there could be an object infront of the subject that makes focusing dificult, like bars, branch, or glass.

>It is also possible that . . . lens . . . contact is intermittent.

Ah, yes. This is also a strong candidate, thank you. As you say, the low voltage may be impeded by mind-bendingly small amounts of corrosion or dirt but, once re-established, the path will tend to remain open. This nearly fits the situation, but fails to explain the successful acquisition of focus by auto-focus prior to the shutter hesitation. (In this instance, AF-C removes all consideration of focus achieved or not.) Presumably such a fault would interfere with the actuation of the focusing motor and make itself known by that association. (BTW, I misspoke, the Tamron has an internal motor but resists hand turning - unlike AF-S lenses - with much the same gusto as a camera drive AF lens.) But, short of setting the camera to MF, I suspect an intermittent bad connection with the lens could indeed make itself known in this manner if it is torn between acting as a valid circuit or an open switch.

I need hardly mention that whatever the problem may be, it is currently in hiding. No doubt the camera heard us talking about it. It doesn't seem to be in the act of changing lenses since the camera has had several different lenses on it in the past few days with no complaint.

Best,

Hendrik
