Take the lens off and rotate the focus ring, it should turn very easily with little gear noise.Try a different AF Pentax lens that you know is good.
I'm sure the lens is binding, take the lens to a camera repair shop for an estimate cost to repair.

Sony a350. Camera motor makes grinding noise when turning on and off. Noise lasts 1-2 seconds. Was not dropped or bumped. Local camera shop said lens not camera.


A few years ago that noise was extremely common on almost all body motor driven AF lenses, and it's not exactly uncommon these days.

Your kit lens is not bad, but it is built down to a price as a get-you-started measure. It's not built as well as the upgrade alternatives and is certainly not built to last nor with repairs in mind.

Your fix is to eventually replace your lens, preferably with one which has a built in motor which will be near silent and far faster to focus. Note that if your lens has become harder work for your camera body focus motor to operate then it will put an extra strain on the motor and can shorten it's lifespan.

Dust or dirt on the zoom track or damaged motor use in manual focus and get it fixed asap,you may damage your body if you AF motor has to strain to focus so maual focus it untill its fixed .

IN AUTO FOCUS FOCUS RING STICKS MAKES NOISE LIKE


How new is the lens? In or out of warranty? If out or warranty most likely solution is to find a Sigma authorized repair shop because your description sounds like the auto-focus motor gear has failed. If in warranty, check out Sigmaphoto.com for repair sites and also download the SIGMA_SERVICE_REQUEST.PDF. I've only had to deal with Sigma once on warranty matter and they were very helpful, provided UPS authorization for shipping on their nickel.

Nikon 50mm 1.4d does not focus. I can hear the motor make a noise and if I Help it, it will turn. Also it seems stiff when off the camera and you rotate the focus ring.


Sorry to hear about your nifty 50 lens problems. The auto focus motor might have given out and needs repair. You should be able to focus manually with the lens.

Weird noises when it's on and zoom button noise picked up on vid


change auto focus to single focus mode,
since it is on continuous auto focus on default, it would focus all the time so you don't need to click half way before taking a picture

Will not focus right, making loud noises.


Your motor may have gone bad. If it makes a loud squeaking noise, it is definitely the motor. Try sending it to PhotoTech Repair Service in NYC. They are Nikon authorized, and can do the repair under warranty if you still have it. Also if you join they're facebook page, they will give you a 10% discount.
Here is the facebook page link, it has everything you need to send it in.

Will not auto focus with a smaller lens.


I had the same issue with my Nikon d60...my 18-55mm did auto focus but my 55-200mm only manual focused, i thought it might have been my camera as i heard that not all lenses are compatible with my d60 but it turned out to be the focussing motor or something that was damaged, it was making a very funny noise when it tried to auto focus with it,like a screeching sound..if this is the case you should get it repaired and looked at, also check on the lens if it says it is a AF lens,if so make sure th switch on the side of the lens is switched on AF not MF. hope it helps

cheers

Auto focus not working


Your Sigma 28-300mm doesn't have a HSM-motor as far as i know. When you switch it from MF to AF, you also have to disengage the manual focusing ring by pulling it towards the camera, or pushing it away from the camera. Using the AF without unlocking the manual focusing ring may damage the AF motor. 
I hope this helps, 
/Chris

55-200mm VR focus noise


The lenses have a focus motor built into them.when the camera is set to auto focus, once you press the shutter button, the motor activates to set the correct focus. VR is for motion stabilization. Turn off AF on lenses and camera and see if noise stops.

Video noise


When in video camera mode, press menu, and change auto focus mode from c (continuous) to s (single). The noise you hear is the auto focus motor going back and forth, trying to find the object focus constantly.
You can use this only if the object is not changing the distance to the camera while recording.
