Chapter One: Comments from the lens design team. 1The dual
challenge of achieving high performance within a compact body.
The solution: Fixed-type lens. - The X100 was originally
conceived as a slim and compact camera for users to take with
them wherever they go. When we first began considering the lens
design, we examined the many possibilities from a variety of
