Creative Mode now employs a simpler focusing method, putting the optimum focus precisely where you tap.
Previously (firmware 1.1.1 build 150 and earlier), tapping the screen while in Creative Mode set the middle of the refocusable range. What this meant in practice was that to achieve best results, you then needed to move the camera forwards or backwards to adjust for objects in the scene, and finally take the picture.
In contrast, the improvements in firmware 1.1.2 will now make the camera more intuitive about focus and relative distances while shooting in Creative Mode. You'll simply tap the object in your composition that's most important, and that's what will be in focus. The current zoom position, focus position, and relative distances are all taken into account under this new approach.
The overarching goal is to simplify capturing great Creative Mode shots. Give it a go and let us know what you think of the change in comments below, we'd love to hear your feedback.
