Yep, the f1.8 made the face of big bear not as sharp as the small one. Btw how do you know the aperture is f1.8, I cant find any exif of the uploaded photo here , Im a rookie to this forum, thanks!Cute. You should close down the shutter a few stops to get the big bear in the last shot completely in focus. f1.8 is just too shallow of a DOF for that shot.
