Question about Nikon Cameras

Open Question

My nikon 16 to 85 mm vr lens won't auto focus below about 20 mm. it won't allow the shutter to release(nikon d300) in auto mode. it seems to focus manually but the ofcus appears to be "soft" in either mode through out the entire zoom range. my nikon 70 to 300 mm vr and tamron 11 to 18 mm work fine leading me to suspect the lens and not the camera. this problem first occured about a week ago. the lens is less than 2 years old so it should be under warranty.

Try re-setting the camera? On the D40 it is 'Menu' scroll down one to Custom Setting Menu (a pencil) and click reset 'ok' yes 'ok' this worked for me.

SOURCE: Nikon D40X stopped auto-focusing yesterday

I had the same problem. My issue was with all my lenses. I solved it by going to the menu and selecting the custom setting menu (pencil icon). Then from the right menu select the AE-L/AF-L and press OK. Then make sure it is set on AE/AF Lock. Presto...all my lenses worked on auto-focus.

Make sure the lens is set for the largest f number on the aperture ring. there may be a lock to prevent the ring from turning in the future. Locking the lens of the largest f number allow the camera to set the lens through the camera. This is normal on most of the newer cameras.

If the lens does not have a move-able aperture ring, then dismount and remount the lens, making sure the lens is completely mounted and locks into place, completely lining up the contacts inside. If this does not work The camera or lens may need servicing.

Make sure your AF-switch on your camera and your lens are both turned on.

My Nikon Nikkor 18-135mm f/3.5-5.6G ED-IF AF-S for Digital SLR lens does not seem to auto focus well. Sometimes the lens will focus and unfocus and refocus constinely. Is this normal??


You did not say which camera body you are using, but you probably have three different auto-focus modes on you camera. You might be using the wrong one.

The modes are as follows:
AF-A Mode: Camera automatically selects single-servo autofocus when AF-A subject is stationary, continuous-servo autofocus when subject is moving. Shutter can only be released if camera is able to focus. AF-S Mode: For stationary subjects. Focus locks when shutter-release button AF-S is pressed halfway. Shutter can only be released when in-focus indicator is displayed.
AF-C Mode: For moving subjects. Camera focuses continuously while AF-C shutter-release button is pressed halfway. Photographs can be taken even when in-focus indicator is not displayed.

It won't take pictures sometimes. push the shutter button and nothing happens.


The Nikon D40 in Auto Focus mode will only allow the shutter to operate when the image is in focus. When looking through the viewfinder, the bottom edge provides information relative to what you are looking at. See the image below:

Item 2 is the focus indicator. It must be illuminated to allow the shutter to release. If it is not illuminated, the lens has not been able to determine the correct focus. This can happen when attempting to take a picture in low light conditions. Make sure that the front facing "focus assist lamp" on the camera (between the shutter release and lens) has not been blocked or disabled (Settings Menu # 09) and try again. Many times, you will see and or hear the lens "hunt" for proper focus - the lens will travel from one end of its focus range to the other trying to find focus. When it can't, it stops and prevents the shutter from releasing. You can get around this "unable to focus" issue by changing the position of the switch on the lens to "Manual Focus" mode, detailed below:

If a lens has an "A - M" switch, move it to "M" to manually focus. If the switch says "M/A - M " then leave on M/A (unless you're going to be taking several or more in manual mode), as these lenses may be focused manually at any time in either position. As soon as you tap the shutter button in M/A you return to autofocus.



More advanced lenses, like the 18-200mm, 70-300mm VR and 18-135mm, and any lens with an M/A position, may be focused manually at any time without moving any switches. Leave them in their A or A/M positions.

I hope this helps and good luck!

Nikon d3000 autofocus issue

Nikon D300 When I depress the shutter half way or fully on my D300 the frame counter reads r27 and the lens (any previously compatible Nikkor lens) will not auto focus. The camera is not set in burst mode...


Only reason the lens will not auto focus when you depress the shutter half way is due to either lens AF switch is set to Manual OR camera body's focus system is on M. There is 3 way toggle switch below the synch port around the lens mount. It should be set to C or S in order for auto focus to work. If all the settings are correct and even "AF-ON", next to rear dial doesn't activate auto focus then the issue maybe in the setting or the body itself. As for the buffer reading r27, I think mine displays r## regardless of burst/continuous mode.

Will Nikon D300 focus with the 11 point AF11 setting?


You may want to consider fine tuning the lenses. I understand that you want the shallow depth of field, but the lens is sharpest at the middle f stops. What is the comparison between a stationary object like an apple or grape (something with a circular shape). I understand you have a higher shutter speed, but the small movements of a person could cause variances in a single focus mode. Are you using the half-shutter press for focus or the AF-E button? Tripod? Remote shutter release?

I asked about the distance relative to the lens length because the DOF can really change based on this. I have found this recently with my macro work so I wanted to find out if you have experimented with this or fired a bunch of shots at a single setup.
