af-s nikkor 18-55mm lens makes buggy noise
My 18-55mm nikkor lens makes a buggy noise, quite loud, like insects communicating, while it auto focuses which is practically constant and even while video recording it records this noise during the video!! Is it normal on this lens and is there a way to mute it? Or is my lens defective? Thanks.

Again, Welcome to Nikonians!
The 18-55mm has a micro-motor and gears that focus the lens.
They do make noise and since the lens is close to the built-in microphone the video will record it. This is true with All DSLR's regardless of brand. The higher end lenses have true Ring motors and are very quiet compared to the entry level lenses that use micro motors. For example my 18-55mm is significantly louder than my 17-55mm.
When shooting video, some focus manually to prevent the noise of the AF motor from being recorded. Others use remote microphones, or both.
Unfortunately since volume is subjective it is impossible to give you a definitive answer without hearing the camera and lens first hand to determine if there is a problem or not.

Thank you for that answer. I believe now it is normal, like you said. It's not abnormally loud I don't think but sure is overwhelming with play back on videos. I'm going to have to mute my films for now. All I make now are short 5-minutes or less films with music over much of the film so this will work out fine. If I need the volume of people talking or something I will probably just manually focus like you said. Thanks for the response.

As you learn more about shooting videos you'll find an external Mic delivers far better sound. Even an inexpensive shot gun shoe mount mic would be a large improvement.
Manual focus is pretty standard even on pro cameras. Since you can't change aperture when shooting using a Variable ND filter on the front of the lens can act like a manual light control and you keep the depth of field as the light changes in a shot. You can manually fade in or out the filter to adjust the light. This is something usually built right into a pro camera. If you want shallow depth of field in bright light it's the only way!
Shooting video manually is really how it's done even with pro cameras too. The auto modes don't really work that well. You can learn to shoot better and get really good results with a D5200 and some practice. Have fun with it and you'll also shoot better stills too. It's a lot less weight to haul around.
