Having problems with your Nikon D90 Digital Camera with 18-105mm lens ?

The autofocus on my D-90 blinks showing F-- and I cannot take a picture with the camera. I have had the camera for about 6 months, but have not used it for about 4 months, Now I can't use it on autofocus at all.


Answers :

I had similar problem and I only had camera for couple weeks. I took 1800 photos in total, and all the sudden, I get this F-- problem. Everything locks up, you can't take photos in any mode. But eventually it will again, and I don't know how, it just does. It doesn' t matter if I switch off or on, it won't make difference. Usually I find if you zoom your lens in and out again few time, it will find focus, and able to shot again. But it is very funny when it locks itself up, it is almost close out the lens. So you only can shot in manual mode, but it's all black. This is more than just a clean job, right?
Try cleaning the contacts on the lens and camera body where they meet with a cotton swab lightly dampened with rubbing alcohol.

My Canon digital rebel will not autofocus correctly. My camera has 7 points autofocus, but it will only autofocus on the far right point. All other points are not used. I have had the camera for 14 months and the problem just began. If I want to focus on anything in the left to center of the field of vision, I cannot do it. However, the lens focuses manually very well. Why won't my camera focus on other points than the far right one?


I had this problem awhile ago - you must have accidently adjusted the focal area - it is sooooo easy to do without realising it. Here is what I was told:**************************Most likely, you have changed the AF point, which onl ... Canon Rebel XT / EOS 350D Digital Camera

My friend left her nearly new Samsung s1070 camera at my house in working condition. Now she has asked for it back and for some reason it just wont turn on.

I have recharged the batteries, changed the batteries, removed and re-inserted the memory card. None of these things have worked it just WONT turn on. I don't have a manual nor am I aware of an

Grainy Pictures I have had my olympus stylus 710 for about 6 months and have been noticing more and more grainy pictures once developed. They are usually when taken indoors. It doesn't look grainy on the LCD screen but when they are developed it is very grainy. This even happens when the flash is used. Any suggestions? Is there a setting I can change for higher quality pictures? I have a gig memory so I don't care if I am going to be using a lot of space. Got 7.1 megapixels and want to use

Battery drainage I have had my olympus sp-550 uz for approx 18 months, and was getting around 175 shots even when using zoom a lot.
