Question about Nikon D50 Digital Camera with 18-55mm Lens

1 Answer

I own a Nikon D50 and the 55-200 lens will not autofocus (lens continually extends then retracts but never locks into focus). Ive read that depressing the lens release button whilst holding the lens in place and swivelling the lens a couple of times sometimes works (cleans muck off the sensors). I tried this but to no avail. Any halp would be much appreciated. Many thanks.

Why don't you just clean the sensors properly? Remove the lens and clean the contacts on both the camera body and the lens with a cotton swab lightly dampened with rubbing alcohol. There's a 50-50 chance something else is causing your problem but try the cleaning anyway.

Nikon D50 will not autofocus, the menue item 02 Autofocus is no highlighed and I can not set it


You should check two switches.

First, on your lens, be sure it's set to M/MA not M. That puts the lens in auto focus mode.

On the camera there should be a switch that shows C/S/M. If switched to M, it's on manual focus. Change this to S for single auto focus or C for continuous auto focus.

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.

I have a weird problem. When i put the 50mm 1.8 on my D90 it continues to autofocus even when I switch the camera body to M mode instead of AF with the switch. I would like to be able to manually focus...


You probably have a problem with the A/M switch on the body-- flipping that switch should extend or contract the autofocus pin that drives the lens. This particular lens doesn't have its own focus motor, so there's no way that it could be focusing on its own without the pin from the body driving it.

Try taking the lens off of the camera and looking at the autofocus pin as you flip the switch from auto to manual focus.

Will the Quanta 28-200 for the Nikon n75 work on the Nikon D5000?


Yes and no. I assume the lens is of more or less the same vintage as the N75? If so, the lens will fit onto the D5000. All of the camera's exposure and metering modes will work properly. However the lens lacks an interal focus motor and thus will not autofocus on the D5000. You can focus manually, and the green focus indicator in the viewfinder will continue to work.

My Nikon D200 just started locking when I depressed the shutter. It gave me the R25 reading in the view finder. If I depress the ae focus lock it fires. What is going on? Cmaclennan@verizon.net


Check your Custom Setting Menu, a1-a10:AUTOFOCUS.

Press Menu, select the Custom Menu Setting (looks like a pencil).
Select "AUTOFOCUS" and move to right.

a1 AF-C Mode Priority. Set to "Focus"

a2 AF-S Mode Priority. Default is "Focus", change this to "Release". This will enable the camera to fire anytime you press the shutter, regardless of if it's in focus or not. Use this setting if your having problems locking up, especially using some different lenses.

Try these settings. They may work for you.

Trouble with auto focus nikon auto nikkor 60 mm f2.8D


Lock it at f/32. Autofocus lenses have a lock for smallest aperture (highest number) because that is wht the camera body expects. The lock won't engage at any other position.

No autofocus


We tried the same lens on another Nikon (D90) and auto focus did not work.
We mounted a new set of lens on the original D40x, and it worked.
Turns out the 2 year Nikon lens (18mm-135mm) was bad. Nikon lens have a 5 year warrantee. The lens will be sent back to Nikon with no service or shipping charge.

Thanks,
K

Will not auto focus


"... Autofocus Lock ("AF-L"). Pressing the AF-L (Autofocus Lock) button enables the Nikon F4 to lock the focus. Simultaneous lock of AF-L and AE-L is possible. "'FREEZE FOCUS" - is another great function in the F4. It allows automatic shutter release when subject enters a pre focused distance - available with Nikon MF-23 and/or the 250 exp. MF-24 Multi-Control Back. i.e. with the shutter button fully depressed, the shutter is automatically fired when a subject comes into a preset manually focused position. This function is recommended for sports races because the racing course is usually known beforehand. It also works well in wildlife remote control photography, scientific, forensic and other technical photography. ..."
