Autofocus Problems

Help!

I've had some problems lately with my Nikon D40's autofocus. When I shoot in manual, shutter priority, or aperature priority, I often have trouble getting my camera to focus correctly. I have the lens set to A or M/A. Sometimes, even when on autofocus, the camera will take the picture and the subject area is not focused correctly. It's happened in varying situations, so I don't think low contrast is the issue.

I use manual focus sometimes when shooting with my macro, but I'm too old and too slow to capture my three-year-old without autofocus! Smile

Any ideas????? Thanks!

I'm a Canon girl, so hopefully a Nikon person will jump in.

What lens are you using?

I've experienced the problem with a couple of different lenses, including my 60mm macro and my 18-55mm zoom.

i have a D80, so the autofocus motor is different. Are you noticing the problem with the center focus spot, on one or more of the outside focus spots, or across the board?

I ask b/c I know that some have reported problems w/ the outer focus spots, but not the center. And the short workaround for that is to use the center focus spot, half-press your shutter, and recompose.

I've noticed when it's focusing on the center spot, but I'll check the other modes, too.

Are you new to shooting manual?

When was the last time you had your sensor cleaned?

I'm pretty new to manual (and to the DSLR). My camera is new, so I've never had anything cleaned. I'm going to try to get some shots in this weekend and test it out again.

I hope you can get it figured out without too much trouble. I've been wanting to say that I love your new siggy pic of the horse and your son, what a huge beautiful horse! Smile

Thanks! One of the ladies on the debate board said the horse was Belgian. There were two, and they were huge but very, very sweet. I was having focus problems at the farm that day but got a few decent shots. I hope to get back there with my camera soon.

That's what I figured he/she was. Just beautiful. A friend of mine just got some really lovely shots of a horse that was cream and chocolate color, with sky-blue eyes. So amazingly pretty!!

I wish Tyler would have hugged him from the other side, so I could have gotten the sun behind me. Unfortunately, as we all know too well, kids have their own priorities! In any case, I love that we have so many farms and parks in the metro D.C. area.
