Originally posted by Another dyemention So I've got two separate autofocus problems and am looking for some help finding a solution.
First, In Low light, the af hunts and hunts and never focuses. Im aware it's because of the lack of light but what can I do to fix it? Manual focusing is not a viable solution since the focus confirmation light doesn't come on. I'm assuming it uses the same sensor as the af. Even when my subject is backlit, like a person in a crowd at a concert, it still has trouble locking on. When it does, it's not the point I wanted to focus on.
Which leads me to my next problem.
Probably about 30-40% of the time, my pictures are not focused on what I was intending to focus on. Even in daylight. When I look at my pictures on the computer, something completely different is in focus. For example I took pictures of my wife on a bench, had the center point on her eye, everything seemed like it focused fine but when I got home, her pants were in focus and not her face. I have the af set to center point and not auto. I have a k50 btw.
Thanks for any input.
On your first question, what is the lens you are using and what are your settings; ISO, aperture, shutter speed? and Are you shooting in A, M, Tv, TAv? Do you have the AF Assist light activated (in the REC Mode menu)? Are you using AF.S or AF.C? The K-50 has very good AF but they all have to have some light and contrast. If you are using a tripod it's a simple solution, go to manual focus and live view. Focus peaking is exceptional in low light shooting, but you need to be on a tripod.
On you second question, first make sure you aren't using AF.C, the slightest movement can change the focus. If in AF.S make sure you aren't in release priority, it's made for continuous hi speed shooting and can fire before focus is achieved. Get your settings and technique down before you get into lens adjustments. I think it would be a real stretch for your lens to be that far out of focus, that would be a serious defect.
