Nikon D5100 Live View mode 'killed' 2 lenses...

I had a Nikon D70s and a AF-S 18-70 for long time and now upgraded to D5100, body only. I was shooting very low angle so used Live View when all of sudden, between 2 shots the lens started to make noises and started to focus-hunt between close focus and infinity, back and forth a couple times before it gave up. Since then the lens can't AF. With or without live view, it doesn't matter. It just go focus creep between the two ends and makes strange noise.

So I needed a new AF lens and I was lucky to find a 18-200 in CEX on a reasonably good price. As I was trying it at home it worked perfectly and silently, as it should. Up to the point I was trying how it works with Live View. Worked fine until all of sudden it started to focus-hunt and making some noise. Since then I didn't turned on the Live View switch as the 18-200 makes the noise all the time.

So probably my D5100 has a problem with live view and it's killing the AF-S lenses...

Obviously I have warranty on the camera, I might have warranty on the 18-200 but absolutely no warranty on the 18-70.

Anyone has any experience with such a situation when a faulty camera with warranty is destroying a lens without warranty. As the damage was caused by the camera's fault, will I get repaired the lenses and the camera as well under warranty? All of them are Nikon products... I feel lucky for not buying the Tamron one...
 
have you tried any of the other lenses on other cameras???
 
They both worked on this camera, but I tried them on the D70s. The 18-70's AF is dead, it hunts non-stop and has a strong noise. The 18-200 works perfectly on both cameras but makes some noise. Both doing it since I used it on the D5100 with live view CAF.

The sound is like a cog is not connecting properly (can't describe it any better... sorry).
 
Call Nikon and please let us know what they say.

That's what you get for using Live View. I never use it and maybe this is a good reason for me to use other than "I just don't need it".
 
Wow. The funny part is that the motor in the 5100 lenses is inside the lenses, not the 5100. The 5100 is just providing electricity.

I hope you are not seriously suggesting this.

Maybe this feature is not very useful to you.

However, it is a widely advertised feature of this particular camera, and for whatever reason it could be very useful to others.

Surely what the OP has described here is abnormal behaviour of at least one component of the system (lens, camera, user), and it should not discourage anyone from using this feature who would find it otherwise beneficial.

On the odd occasion I also find myself using live view, and would be very much interested to find out what actually went wrong with the OP's system.

I don't see how this could be caused by the camera. There is no mechanical connection between the camera and lens motor.

I think you first have to determine that it is indeed the camera fault and that the lenses are indeed broken. And it can also still be a weird coincidence. Have you tried the lenses you mention on another camera to determine if they do or do not function on another body? Maybe your lenses are still okay, but that your D5100 body has a problem.. From your explanation neither option can be excluded.

You say your 18-200 "might" still have warranty, so I presume you got a used sample? Do you know for sure that this lens was flawless when you got it from the first owner?

But I have not heard this kind of story yet. I think you'd better contact a Nikon Service Point for information.
 
Live View is a good thing especially with vari-angle LCD if you shoot very low angles. The problem is not because the Live View mode, it's because a possible fault with the camera.

While the body has no motor and the motor is inside the lens, it's still the body who says the lens what to do. It might be a problem with the CAF or something else in my camera (and not a 'system fault' with the D5100).

I tried the lenses on other bodies (D70s, D300 and a D40x), yet none of them had live view mode. Before the problem started the lenses worked fine, after the problem first occured it happened on all other cameras as well, so it seems a permanent damage in the lenses. But even on my D5100 it worked fine for a while (bit longer with the 18-70) with or without live view.

I've contacted Nikon UK, waiting for their reply.
 
I don't see how this could be caused by the camera. There is no mechanical connection between the camera and lens motor.
Many electronic items are very intolerant of voltage or amperages outside of the expected range. It's entirely conceivable that there's a flaw in the OP's camera that's exacerbated or revealed when using the contrast detection AF system.
 
Have you never heard of a device damaging another, electrically? Signals received by a device, outside it's normal operating parameters could damage said device. There doesn't have to be a "mechanical connection" in order for one component to damage another.
