Camera dropped an the lens broke off the camera

It seems like you've got a broken lens mount on the 18-105mm. Take a look at the backs of the two lenses. You should see the bayonet mount with three flanges. If one or more of the flanges on the 18-105mm are broken then the lens won't stay on.

If you feel up to doing the replacement yourself, you can order the part from

As to whether you can replace it yourself, can you use a screwdriver and a soldering iron?

Unfortunately, Nikon does not incorporate better built into the kit lens. If the break is merely cosmetics, my advice is to try to repair it or live with it. Most times, the repair cost may exceed the $100-$125 [used price] of the 55-200mm lens.

which rim are you talking about, the bayonet mount?

Only try this if your camera is out of warranty. Turn camera on, and extend lens fully, now grab outer most element and pull out. Sometimes you can reseat the lens in the track at the correct point. I used to do this all the time to my older digital cameras.

I'm another very unhappy victim of the defective manufacturing and/or materials in this lens. My 18-105 DX VR lens lived in a padded camera bag when it wasn't on the camera. It's never been dropped, banged, dinged, or put under any stress. 10 months into ownership, with 50 months to go on the 5 year extended warranty, it simply came off in my hand one day while zooming. I was horrified to see a thin black plastic sliver inside the camera body -- the mount just broke off. Thankfully did not get behind the mirror or on the sensor. Greatest insult came from Nikon repair, who refused to honor the warranty because "the lens had been dropped" and asked me to pay nearly 1/3 the original cost of the lens for repairs. When I challenged this and pointed out the as-new condition of the lens, not even a scratch, they simply stopped responding to my emails and phone calls.

I feel for you. exactly the same happened to me but i was looking to upgrade lens so i used it as an excuse.the piece is called a bayonet. what lens is it, is it the kit lens. my lens was unfixable so  am afraid as the mount is plastic the whole lens is a right off, if it was a metal mount it would be worth fixing. sorry
