The auto focus on my D 300 still works but I have noticed it does not focus very quick especially if it is not bright. I do a lot of portraits indoor and sometimes it is embarrassing how long it takes before it fires. I also have a D70s and it does not do this. Any ideas. Also the assist light is turned on. Thanks, John
Not sure what the cross sensor is but yes I am using central AF. Thanks Anthony. I did some tests with my D 300 and d70 yesterday in my living room taking identical shots with both cameras with the same 50mm lens and it maybe is not as bad as I thought but the D70 will still focus a little quicker than the 300.

Hi Marty, Just to let you know, I tried both your suggestions without success. Seem the problem is the body, as no other lenses will focus. Must be electrical issue I suppose. Cheers. Hugh

I've had my D300 for 3 years now and nver knew about the resetting option. A million thanks, ArthurNikonF - it worked! Problem solved! And, like a computer, resetting the unit can get it back on track. Then again, the D300 is much like a a wonderful PC.
