To check new ability of six magnification zooming on Fine Camera V1.40, I’ve been to Nogeyama Zoo in Yokohama.
If you want to reset the zooming magnification, double tap on orange circle.
If you want to on-off the semicircular slider for zooming, tap magnifying glass icon on the extreme right.

This version conformed to iOS8.3, iPhone 6 and iPhone 6 Plus.
And, several minor faults were fixed.
Here are examples of iPhone5, iPhone6 and iPhone6 Plus.
Because display width becomes larger like 5s -> 6 -> 6 Plus, selectable effects in a display increase accordingly.
