I have just bought seconhand a Canon 28-105 Ultrasonic EF lens. The seller admitted the lens had not been used for a while. After about a week of use the zoom ring began to stick at around the 50mm point.
My solution has been to remove the lens and gently "exersize" it by twisting the zoom through its full range about thirty or more times. It now appears to be working ok.

Re: Zoom ring on 18-55 mm lens is locked/stuck
Are you sure it's the zoom ring that's stuck, and not the focus ring? The focus ring doesn't move when the camera is in autofocus.
If it's indeed the zoom ring that's stuck, you can spend more money than the lens is worth in repairs, or buy a replacement (circa 35 dollars on ebay) for dreadfully cheap. Good luck.
a 6ya Expert can help you resolve that issue over the phone in a minute or two.

there must be a problem with the lens ring which are fitted inside, occasionally it gets worn out because of improper handling . alignments may have caused you the problem. but once again you need a professional help because you wont get any elements or parts easily except from the company.this lens could also may have jammed due to any reasons, may be a foreign body or so and because the af is OK you are still getting a sharp image up to actual 45 mm which you think to be 55mm. If i were you then I would have inverted the lens and tapped gently and then check it once again or best goto Nikon service centers .
Sorry, but salt water immersion is effectively just as destructive to your camera and lens as if they had been crushed or burnt. If the body and lens were immersed in seawater then they are complete write-offs as they will be completely beyond economic repair.
Hi Rachael_amor, If the lens will not zoom on the camera will it off the camera? If not then it has some grit, dirt, and the like in the lens. You could attempt to vacuum around the zoom however, I suspect it will need to go in to Nikon. That lens is not well weather sealed, it is a inexpensive consumer lens.
2) I do not understand your assertion that it automatically zoomed in. Zooming is a manual function. The automatic functions of your lens pertain only to focusing on of the subject so that your picture is sharp and ensuring that the correct amount of light is admitted so that you have a correct exposure.
3) Are you sure you were turning the zoom ring and not the f-stop ring? The zoom ring is labeled 200 on one end of the scale and 55 on the other. It is also the widest ring on the lens barrel. When you rotate it, the physical length of the lens will lengthen as you rotate it clockwise (viewed from behind the camera) and shorten as you rotate it counter-clockwise.
4) For reference, at 200mm the angle of view on your lens should be 10 degrees and at 55mm about 40 degrees.
I fix it!
This problem is due to bad design (I think)
The problem is cause of the guards/holder/stand bends a little the you turn the zoom.
I bend the guards just a little to the left.
This get the guards to stand straight then you "zooming".
Perhaps a little grease can help too, but what kind do you use inside a kamera?
My lens started catching as I zoomed in and out and would not go wider than
~24mm. The problem is one or more of the screws holding the zoom
mechanism comes loose and jams. Follow this link for the fix; took me
~20 min to repair (I went very slowly)! Much easier than taking it apart from the rear.
