My lens makes electrical short circuit like noise when it tries to auto focus. It is not too loud. But is it normal or did I receive a bad copy?

It's most likely the VR you're hearing. It sounds like an electrical circuit.

I've never heard anything beyond the usual focus motor sounds coming out of mine, so it sounds like somethings amiss.

I have the same lens and it's my favorite lens. Mine does not make any noise like you've described.

I don't know what a short circuit sounds like... but the lens is very quiet and not much different from another lens that I have... 70-200mm f2.8 and 35mm prime.

mine does too- it's a very noisy lens from what I can find out on the internet- not sure howl oud yours is, but mine was kinda loud- thought it was defective too- but the lens works fine, focuses fine- etc- the noise mien makes is like a cross between a motor noise and a grinding noise=-

My lens has a Focus motor but I have a Canon version. So I don't know about Nikon's errors.

Auto focus is used when the distance of a device changes, with that said this camera has a fixed distance And a fixed electronic focus. Unless your electronics have failed that is probably not your problem. A more likely problem is that your lens has moisture on it from the inside. This camera is known to allow it inside.Look at the lens if it is foggy take a hair dryer and blow on it until the moisture is gone then seal the unit well with a clear caulk. Hope this helps!

I haven't notice any loud motor noise when my lens focuses, just a little click noise when the motor starts or stops when focusing. It's about the same as my 24-120 mm or my 70-300 mm lenses.....not much Hope this helps.

I second guessed myself as well in the beginning. The lens has a pretty long manual throw. i.e. it takes some big turns to get things into focus manually. Keep trying and it should eventually get things into focus.

Yes, I have not had any issues with this lens, in fact, I love it. I use the auto setting on the camera and all pics have been great!

No its not defective,no auto feature on it.Its all manual and to focus you must get move in and out to the subject your shooting.Its hard to do with this set there are others that let you use the cameras settings that are better.

Mine does the same thing. Lens seems to work just fine. Probably has a friction clutch which permits the focus ring to turn past the stops

Hi Chris,Is this lens new or used? Because as of today it's malfunctioning while zooming in-out

My Sigma 1.4 lens isn't focusing properly. Purchased it Oct.9th. Won't focus past 6 feet. I have to send it to Markam Ontario for repairs. And it will cost me for repairs. No warranty?????

Bad one. Should just work smoothly. You should not notice it - except having to focus manually. ;)

The clicking is normal. It stops when you attach the lens to your camera and power it on.

No thats not normal. But make sure the focus ring is in the right position. Push it forward for autofocus, pull it back (toward the camera) for manual focus.

Jenna, I do not have this issue. There is a slight noise while focusing but not a loud noise. Possibly take to a local camera store to checkout? Good luck. Rich.

For mine, it does make a noisy sound but it is not too loud while it does the auto focus. I really like this lens though. very sharp!

If you are using the reverse mount, you are mounting the lens backwards. This means there will be no electric connections to the camera. You must set your lens to manual and adjust the focus and exposure manually, otherwise it will not work. Which lens are you using? Did you attach the ring to the front of the lens glass or the cameras lens mount?
