d70 repair $380!!

[jobo]

NSC is so darn expensive leh. Even parking there is expensive, unlike the free parking previously. What's the point of having a spanking new office right inside the CBD.

However, there is a way out - remember this joint called TCW, cheap and good. :thumbsup:

TCW? where is it...appreciate the info...thanks

Try cleaning the lens mount contacts with some isopropyl alcohol or philips contact cleaner. The problem may just be dirty contacts on either the D70s or kit lens.

If it was working when you put it away, I don't see how it could have become spoilt just sitting unused.

the problem was, when i shot landscape..it focused just fine...indoors became a problem. furthermore when i brought it to NSC they tried it on the spot and it just didnt even run, meaning couldnt even hear the autofocus sound...later they told me it was the body..:think:

FYI, SWM or ultrasonic motors work by sending waves of ultrasonic 'pulses' to move. There is no contact between the 2 moving surfaces. If it squeals, it suggests that there is contact between moving parts.

can go after CBD operation hours. They just extended their opening timings on certain day right?

nope.tat is incorrect.
it is AutoFocus SILENT-Wave. it is meant to be silent, quiet.

my new SWM motor does not produce the squealing, squeaking sounds anymore.

... and your point is:

• a CLA will get the job done OR
• completely change the SWM before it breaks down during shooting?

There is contact.. SWMs are piezo-mechanical in nature and can be likened to how a snake moves by slithering. OTOH, brushless induction motors do not contact but rely on Faraday forces due to magnetic induction.

Anyway, I think my 18-200 VR squeaks less now that the humidity of the dry cabi is set to around 47%. I will monitor the situation. I think those with AFS lenses should have the humidity set between 45% and 50%.

so long as it works soundlessly... :bsmilie:

it will break down.
it will fail to focus.
but when?

i had the same thinking as u before, as long as it is still kicking and working, who cares?
dun fix it if it ain't broke. right?:bsmilie:

and best of it all, this is really wat happened to me at a shoot. u might want to avoid the same silly mistake that i made.
and i manual focus throughout the whole event. how exciting.:bsmilie:

Hmmmm.....

Did NSC indicate in anyway that this was due to an older SWM design and that the replacement SWM module is redesigned not to squeal and failure after some time? Reason why I'm asking this is that I don't want to fall into a trap of taking the SWM thingy as a consumable, i.e. there is a useful life to the SWM, after that point pay the price to continue enjoy autofocus :dunno:

nope. i wasn't told of anything that explicit, u knw?
all i was told, 'hey, ur SWM is down. it ain't supposed to make noises like that and the AF can't lock on'... u know the works.

so a complete overhaul of the SWM is needed, (of cos i know this)but i ain't prepared for the huge fee! :bsmilie: S$300 for workmanship is a bit steep if u ask me.

as i've said before, there are some others with the same problem as us, with the same lens. i think that it is due to old age and hence the break-down of the SWM.

and i forked out the excesses and now i'm rewarded with a spanking new SWM and my AFS17-35 f2.8D roxxxxxxxx once again. :thumbsup:

i dun trust 3rd party to do the repair work, u see?

TCW? :bsmilie:

Sorry, a few more questions: How old is your lens? How heavy is your use? Do you keep it in a dry cabinet when storing, if yes what is your humidity setting?

I stand corrected. you're right, lenses use contact USMs. However, I feel squealing is still abnormal. I would think that there is foreign particles between the stator and rotor.

i keep my lens at my box around 45-55.

heavy only in event coverage and in portraits.
landscape always in manual focus.

my lens is an oldie. more than 2yrs old. for ur info, all is not smooth when i got back my lens after the SWM is changed. it failed to focus with my D200 at a distance of over 10meters and i failed to notice this till around 1month later after repair(becos i jus got my D200 not long ago)! so back again to NSC to get the dunno-wat changed and now it is back to its best again.

anything u wanna know? jus ask. its good for everyone here in the forum.

do not accept squeaky AFS lenses!

paiseh, failed to catch ur underlying intention and meaning.

 

[vince123123]

There is a serious quality control concern on the SWM - there are MANY cases of squeals in the SWM after some time - or maybe this is planned obsolecense - these things break down after a while and force someone to replace/repair.

The funny thing is that these are supposed to be the flagship top of the line lenses - Nikon needs to get its act together if they want to sell top of hte line stuffs that don't break down so easily. Lenses are supposed to last a long time.

By the way, this is a very common problem in AFS lenses. THe total cost to fix is around $7-800 if I remember correctly (That was some time ago when quoted so correct me if you have firmer figures).

 

[ipin]

I reckon that regular maintainence and servicing would minimise the problems.

Any example to back up this claim?
So far i have not heard much about this problem.
