someone help me :)

[siddant]

I have a Nikon D90 with a 18-105 F1.5-6 kit lens.
When I try to take a picture in A,M,S,P or even in Auto mode sometimes, the F keeps flashing and wont let me take a pic.

If I turn it off and retake the same snap sometimes it works.

I am extremely agitated that it does it.

Can someone please help me with what am doing wrong.

It probably is someting very silly but yea I cant get it

Thanks again

umm, usually this happens when the lens is not properly locked into the "auto" apperture, usually it's smallest apperture, with that little switch thingy on the apperture ring of the lens.

What a shocking explanation, hope you follow that !!

Not sure; what does the manual say the flashing F means?

Thanks Darren,

I did try that and doesnt fix the problem. I set the mode to manual , then turned off the autofocus on the lens and also turned off AF on the camera body as well .

All of that to no avail.

oh well. I am reading the manul again to figure out whats wrong.

Thanks for the quick reply .

Cheers

What Darren means is. On your lens there will be an aperture 'dial' where you can dial the lens to f3.5 / f8 / f22 etc. In film days we used to dial up the aperture we wanted to use, by turning that dial.

Digital cameras control the aperture from the camera, so for it to work, you have to have the aperture dial on the lens 'locked' as far as it will go at the f22 end of the dial, otherwise your camera will give you the F message (cause the camera cannot control the aperture, unless the lens dial is in the locked position). Some lenses also have a little slider next to the aperture dial that you slide one way or the other to ensure the aperture lock is engaged.

When you took your lens off and on you probably and inadvertantly, adjusted that dial, which then made your lens work.
