Default Some E-520 AF Questions

I have some E-520 A/F questions when it comes to close ups on Dark colored objects.Out door pictures dark Brown and Black using my 14-54 MK1
Most of my close up brown and black objects turn out blurry in " Not the best light " Very Cloudy . It apperasd more as the object is close . Under 10 '.
But objects over 15 feet away they are better.
I am using SAF usually f 4 shutter 150 or over.
Is it a setting I can check, or is it the Nut behind the camera loose ??

Thanks for any help

Olympus cameras need for AF high contrast subjects, this is not an issue only of your E-520 I have the same problem (less magnitude) with my E3 or E5.

In low light conditions or if you are focusing flat dark objects the camera/lens will hunt trying to find a spot with contrast.

Just my 2 cents.

Unfortunately there is no exif data on those pictures... the first one looks ok but the second the AF is off, what shutter speed did you use? It was the owl balancing? maybe the AF is off because motion blur?

The PSE 8 I use to downsize blows away the EXIF
The OWL was very still

Shutter 125 f 4.0 Focal length = 54mm ISO 200 Owl

Shutter 200 f 4.0 Focal length = 54mm ISO 200 Tree

Black car with good light, a BIG difference approx 10 ' away

Shutter 400 f 4.0 Focal length = 54mm ISO 200 Car

I think the picture of the owl is blur not for AF issues, I think the problem is motion blur what creates the problem. The shutter speed was to slow (1/125)... if the owl was balancing because the wind you need at least 1/600 or 1/1000 to freeze the action and you have to take in consideration also the movement of your body while shooting the picture.

If you noticed your camera have problems focusing on dark subjects this is a common issue with Oly cameras, with the E5 and the SWD lens sometimes I have the same problem.

The picture of the car is sharp and I think your camera locked focus because all those reflections on the black paint.

Have a great day.
