Re: Front focus problem
Hey hubro, This switch is used to set a focus point to so you can quickly focus to the preset distance. What you have to do is set the switch to the on or on with sound setting then focus to the distance you want to preset and then press the set button. While this switch is set to the on or on with sound setting you just turn the focus preset ring which should be in front of the focusing ring and the camera should focus to the preset distance. I hope this helps! Sincerely, Allan Go Ahead. Use Us.

The sound may be the result of the auto focus motor operating to keep the subject in focus. You may be able to shut off the auto focus by switch on the lens (if provided) or camera body menu and focus manually instead.
For Nikon AF and manual focus SLRs. The compatible T Mount System makes it possible to use most any single lens reflex camera in combination with various front camera attachments such as telescopes, mirror lenses and slide duplicators. The T Mount is a metal connector that screws onto the compatible front attachment and allows this combination to be coupled to the SLR camera lens mount.
In "full" mode, the auto focus will use the whole range of the lens.
In "half" mode, only half the range will be used.
Limiting the range to half, makes it auto focus faster. The half mode should be used when you are taking close ups. This will keep the lens from focusing on objects far away by accident.
Hope that helps!
AF=Auto Focus. With an autofusu capable body, the camera will automatically focus for you using preset focusing zone. Move the Switch to:
MF and it becomes a manual focus lens, where the photographer has to manually focus on his subject.
Set either the camera or lens (or both) to manual focus. Most Nikon cameras have the focus selector switch on the front, under the lens release button.
Look through the viewfinder and turn the focus ring until the image (or at least the subject) appears sharp. A green light will light up when the camera thinks the subject under the currently selected focus sensor is sharp.
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.
I recommend that you print this test chart: http://www.photo.net/learn/focustest/scale45.jpg
Just print it on an ordinary paper, then put it on a table, and take a picture at it from a 45 degree angle, using the center focusing point only, aimed at the thicker line in the middle. The numers are centimeters. Take the test picture at f/1.4. Make sure you have good light so you get a fast shutter time. If you have a tripod, mount the camera on the tripod prior to taking the test picture.
Then examine the picture in your computer, zoomed to 100%. Now it should be clear wheter you got back- or front focus, and how large the problem is.
Unfortunately, there is no way for you to adjust the camera and lens combination yourself, you will have to send/bring the camera to an autorized camera workshop. This is covered by the warranty.
Hope this helps!
Your camera is only compatable with AFS-type lenses because it has no screw-drive motor. You can only use AFS Nikkors and Sigma HSM lenses (the lens actually has a motor inside). You were misinformed. Bring the lens back and ask for a refund. Take that money and purchase a compatable lens somewhere else.
